     DESCRIPTION OF EMBODIMENTS 
     Knowledge Underlying the Present Disclosure 
     When a lifetime of a vehicle is shorter than a lifetime of a secondary battery mounted on the vehicle, there is a likelihood that the secondary battery is disposed of together with the vehicle even though the secondary battery is still sufficiently usable. In view thereof, the wasteful disposal of a secondary battery can be prevented by controlling the vehicle such that the remaining lifetime of the secondary battery approaches the remaining lifetime of the vehicle. 
     However, the conventional technology aims at estimating when, what quantity, and what quality of reusable secondary batteries will be supplied. Therefore, the conventional technology fails to take into account controlling the vehicle such that the remaining lifetime of the secondary battery approaches the remaining lifetime of vehicle when the remaining lifetime of the vehicle is estimated to be shorter than the remaining lifetime of the secondary battery. 
     In order to solve the problem described above, an information processing method according to an aspect of the present disclosure, which is executed by a computer, includes acquiring first data concerning a load applied to a body of an electric mobile apparatus, acquiring second data concerning the performance of a battery mounted on the mobile apparatus, calculating a remaining lifetime of the body on the basis of the first data, calculating a remaining lifetime of the battery on the basis of the second data, comparing the remaining lifetime of the body with the remaining lifetime of the battery, and instructing at least one of an activation of an unused function and an enhancement of a used function among a plurality of functions consuming the electric power of the mobile apparatus when the remaining lifetime of the body is shorter than the remaining lifetime of the battery. 
     In this configuration, when the remaining lifetime of the body is shorter than the remaining lifetime of the battery, at least one of an activation of an unused function and an enhancement of a used function among a plurality of functions consuming the electric power of the mobile apparatus is instructed. Therefore, the remaining lifetime of the battery of the mobile apparatus can be made to approach the remaining lifetime of the body of the mobile apparatus. This can consequently prevent a disposal of the battery still having a lifetime together with the body having no lifetime. Further, the activation of an unused function or the enhancement of a used function can increase the convenience for a driver. In other words, the remaining lifetime of the battery of the mobile apparatus can be made to approach the remaining lifetime of the body of the mobile apparatus by efficiently consuming the lifetime of the battery of the mobile apparatus. 
     Further, it may be appreciated in the information processing method that, in the instruction, at least one of the activation of an unused function and the enhancement of a used function is presented on a presentation device, at least one of the function to be activated and the function to be enhanced is determined on the basis of a response to the presentation, and the determined at least one of the activation of the function and the enhancement of the function is instructed.

     In this configuration, at least one candidate of a function to be activated and a function to be enhanced can be determined in such a manner that at least one of a reduction of the remaining battery lifetime due to the activation of an unused function and a reduction of the remaining battery lifetime due to the enhancement of a used function is kept from exceeding a difference between the remaining battery lifetime and the remaining body lifetime. In other words, an excessive enhancement of the consumption of the battery lifetime can be prevented. 
     It may be also appreciated in the information processing method that, in the presentation, at least one of a type of the mobile apparatus, a use mode of the mobile apparatus, and a use record of the mobile apparatus is acquired, a priority degree of the presentation of at least one of a function to be activated and a function to be enhanced is determined in accordance with the acquired at least one of the type, use mode, and use record of the mobile apparatus, and at least one of the activation of an unused function and the enhancement of a used function is presented on the presentation device according to the determined priority degree. 
     In this configuration, a priority degree of the presentation of at least one of a function to be activated and a function to be enhanced is determined in accordance with at least one of the type, use mode, and use record of the mobile apparatus. Therefore, for example, the presentation of at least one of a function to be activated and a function to be enhanced in a descending order of priority degree enables the manager to easily select at least one of a function to be activated and a function to be enhanced. 
     It may be also appreciated in the information processing method that, in the instruction, a difference between the remaining lifetime of the battery and the remaining lifetime of the body is calculated, at least one of a function to be activated and a function to be enhanced is determined in accordance with the difference, and the determined at least one of the activation of the function and the enhancement of the function is instructed.

     When the remaining lifetime of the body calculated on the basis of the body load data (first data) is shorter than the remaining lifetime of the storage battery (battery)  14  calculated on the basis of the battery load data (second data), the communication part  19  receives a notification instructing at least one of an activation of an unused function and an enhancement of a used function among a plurality of functions consuming the electric power of the mobile apparatus  1 . 
     The drive control section  151  executes at least one of the activation of an unused function and the enhancement of a used function in accordance with the notification received by the communication part  19 . 
     Here, the functions consuming the electric power of the mobile apparatus  1  will be described. 
     The functions include functions of controlling the travel in the mobile apparatus  1 . The functions of controlling the travel include, for example, a function of controlling an acceleration, a function of controlling the quietness, and a function of controlling a drive assistance.

     Alternatively, when a notification instructing an enhancement of any one of the used functions of cooling air, heating air, humidifying air, dehumidifying air, and purifying air is received, the drive control section  151  enhances any one of the used functions of cooling air, heating air, humidifying air, dehumidifying air, and purifying air. 
     Further, the functions include a function of supplying an electric power to an outside of the mobile apparatus  1 . When a notification instructing an activation of the unused function of supplying an electric power to the outside is received, the drive control section  151  activates the unused function of supplying an electric power to the outside. For example, the drive control section  151  activates the function of supplying an electric power to the outside of the mobile apparatus  1  by supplying the electric power to a USB (Universal Serial Bus) port provided on the mobile apparatus  1 . 
     Further, the functions include a function of performing communications, or a function of performing an external connection by use of the communication function of the mobile apparatus  1 . When a notification instructing an activation of the unused function of performing communications is received, the drive control section  151  activates the unused function of performing communications. For example, the drive control section  151  activates the function of performing communications of the mobile apparatus  1  by permitting communications between the mobile apparatus  1  and an external device via a wireless communication. 
     Further, when a notification instructing an activation of the unused function of performing an external connection by use of the communication function is received, the drive control section  151  activates the unused function of performing an external connection by use of the communication function. For example, the drive control section  151  activates the function of performing an external connection by use of the communication function by permitting communications between the mobile apparatus  1  and the external device via a wireless communication, and operating the mobile apparatus  1  and the external device in connection with each other. For example, when the external device is an intercom, the intercom sends a captured image to the mobile apparatus  1 , and the drive control section  151  displays the received image on an unillustrated display. 
     The actual electric power consumption value measuring section  156  measures an electric power consumption in the case of activating an unused function among functions consuming the electric power of the mobile apparatus  1 . Further, the actual electric power consumption value measuring section  156  measures an electric power consumption in the case of enhancing a used function among the functions consuming the electric power of the mobile apparatus  1 . 
     For example, the actual electric power consumption value measuring section  156  measures an electric power consumption in the case of actually accelerating the mobile apparatus  1  by enhancing the used function of controlling the acceleration of the mobile apparatus  1 . The actual electric power consumption value measuring section  156  may measure an electric power consumption before the enhancement of the function of controlling the acceleration of the mobile apparatus  1 , and measure an electric power consumption after the enhancement of the function of controlling the acceleration of the mobile apparatus  1 . Thereafter, the actual electric power consumption value measuring section  156  may calculate a difference between the electric power consumption after the enhancement of the function of controlling the acceleration of the mobile apparatus  1  and the electric power consumption before the enhancement of the function of controlling the acceleration of the mobile apparatus  1 . 
     Further, for example, the actual electric power consumption value measuring section  156  activates the unused function of controlling the quietness of the mobile apparatus  1 , and measures an electric power consumption in the case of running the function of controlling the quietness. The actual electric power consumption value measuring section  156  may measure an electric power consumption before the activation of the function of controlling the quietness of the mobile apparatus  1 , and measure an electric power consumption after the activation of the function of controlling the quietness of the mobile apparatus  1 . Thereafter, the actual electric power consumption value measuring section  156  may calculate a difference between the electric power consumption after the activation of the function of controlling the quietness of the mobile apparatus  1  and the electric power consumption before the activation of the function of controlling the quietness of the mobile apparatus  1 .

The remaining body lifetime may be expressed in the form of a remaining time which the mobile apparatus  1  can travel up to. The remaining body lifetime calculating section  223  stores the calculated remaining body lifetime in the remaining body lifetime storing section  239 . 
     In the present Embodiment 1, the remaining body lifetime calculating section  223  calculates the remaining body lifetime on the basis of the initial lifetime of the body and the number of shakings of the body, but the present disclosure is not particularly limited thereto.

The memory  23  stores in advance a function representing a relationship between the number of charge and discharge cycles and a full charge capacity. The remaining battery lifetime calculating section  224  calculates a current full charge capacity of the storage battery  14  on the basis of the number of charge and discharge cycles acquired from the charge and discharge history storing section  231 . The remaining battery lifetime calculating section  224  calculates, as a chemical remaining battery lifetime, a difference between the calculated current full charge capacity and a full charge capacity diagnosable as an end of battery life.

In this case, the memory  23  stores in advance a function representing a relationship between a full charge capacity and a remaining travel distance. The chemical remaining lifetime may be expressed in the form of a remaining time which the mobile apparatus  1  can travel up to. 
     In the present Embodiment 1, the remaining battery lifetime calculating section  224  calculates the chemical remaining battery lifetime using the number of charge and discharge cycles, but the present disclosure is not particularly limited thereto. The remaining battery lifetime calculating section  224  may calculate the chemical remaining battery lifetime using other information concerning the performance of the storage battery  14  such as the SOC, the SOH, the temperature, or the total electric discharge of the storage battery  14 . 
     The remaining battery lifetime calculating section  224  acquires the number of shakings of the housing of the storage battery  14  stored in the battery mechanical load history storing section  232 , and calculates the mechanical remaining battery lifetime of the storage battery  14  on the basis of the acquired number of shakings. The memory  23  stores in advance a function representing a relationship between the number of shakings of the housing of the storage battery  14  and a mechanical remaining battery lifetime. The remaining battery lifetime calculating section  224  calculates a mechanical remaining battery lifetime of the storage battery  14  on the basis of the number of shakings acquired from the battery mechanical load history storing section  232 . The mechanical remaining battery lifetime is expressed with the same unit of measure as the chemical remaining battery lifetime. The mechanical remaining battery lifetime may be expressed in the form of an amount of electric power, or may be expressed in the form of a remaining travel distance which the mobile apparatus  1  can travel up to. Besides, the mechanical remaining battery lifetime may be expressed in the form of a remaining time which the mobile apparatus  1  can travel up to. The remaining battery lifetime calculating section  224  stores the calculated mechanical remaining battery lifetime in the mechanical remaining battery lifetime storing section  234 . 
     The remaining battery lifetime calculating section  224  calculates, as the remaining battery lifetime, one of the chemical remaining battery lifetime stored in the chemical remaining battery lifetime storing section  233  and the mechanical remaining battery lifetime stored in the mechanical remaining battery lifetime storing section  234  which is shorter than the other, and stores it in the remaining battery lifetime storing section  235 . 
     In the present Embodiment 1, the remaining battery lifetime calculating section  224  calculates the remaining battery lifetime on the basis of the chemical remaining battery lifetime and the mechanical remaining battery lifetime, but the present disclosure is not particularly limited thereto. The remaining battery lifetime calculating section  224  may calculate only the chemical remaining battery lifetime as the remaining battery lifetime, or may calculate only the mechanical remaining battery lifetime as the remaining battery lifetime. The battery load data (second data) includes a history of at least one of a charge, a discharge, a charge capacity, and a temperature of the storage battery (battery)  14 . The remaining battery lifetime calculating section  224  may calculate the remaining lifetime of the storage battery (battery)  14  on the basis of a lifetime of the storage battery (battery)  14  and a deterioration level of the storage battery (battery)  14  calculated from the history of the storage battery (battery)  14 . 
     The actual electric power consumption value acquiring section  225  acquires an actual value of electric power consumption of each function sent from the mobile apparatus  1  via the communication part  21 . The actual electric power consumption value acquiring section  225  stores the acquired actual value of electric power consumption of each function in the actual electric power consumption value storing section  241 . 
     The lifetime shortening effect estimating section  226  reads out an electric power consumption of each function from the electric power consumption storing section  240 , reads out an actual value of electric power consumption of each function from the actual electric power consumption value storing section  241 , and corrects the electric power consumption of each function using the actual value of electric power consumption of each function. For example, the lifetime shortening effect estimating section  226  replaces the electric power consumption of each function with the actual value of electric power consumption of each function. Further, for example, the lifetime shortening effect estimating section  226  may calculate an average value of the electric power consumption of each function and the actual value of electric power consumption of each function, and replace the electric power consumption of each function with the calculated average value. The lifetime shortening effect estimating section  226  stores the corrected electric power consumption of each function in the electric power consumption storing section  240 . 
     The lifetime shortening effect estimating section  226  may correct the electric power consumption of each function using an actual value of electric power consumption of each function acquired from another mobile apparatus of the same type as the mobile apparatus  1 . In this case, the communication part  21  acquires the actual value of electric power consumption of each function measured in another mobile apparatus of the same type as the mobile apparatus  1 . 
     Further, the lifetime shortening effect estimating section  226  estimates a lifetime shortening effect of each function on the basis of an electric power consumption of each function. The lifetime shortening effect refers to a length of lifetime which can be shortened when an unused function is activated or a used function is enhanced. The memory  23  stores in advance a function associating an electric power consumption with a lifetime shortening effect. The lifetime shortening effect estimating section  226  estimates the lifetime shortening effect of each function on the basis of the electric power consumption of each function using the function. The lifetime shortening effect estimating section  226  stores the estimated lifetime shortening effect of each function in the lifetime shortening effect storing section  242 . 
     The lifetime shortening effect estimating section  226  corrects the electric power consumption of each function stored in the electric power consumption storing section  240  using the actual value of electric power consumption of each function stored in the actual electric power consumption value storing section  241 , but the present disclosure is not particularly limited thereto. The lifetime shortening effect estimating section  226  may estimate the lifetime shortening effect of each function solely on the basis of the actual value of electric power consumption of each function stored in the actual electric power consumption value storing section  241 . In this case, the server  2  is not required to store in advance a standard value of electric power consumption of each function, and thus can reduce the occupied storage capacity in the memory  23 . Further, the lifetime shortening effect estimating section  226  may estimate the lifetime shortening effect of each function solely on the basis of the standard value of electric power consumption of each function stored in the electric power consumption storing section  240 . In this case, the mobile apparatus  1  is not required to measure an actual value of electric power consumption of each function, and thus can reduce the processing load for the mobile apparatus  1  and the server  2 . 
     The remaining lifetime comparing section  227  compares the remaining lifetime of the body with the remaining lifetime of the storage battery (battery)  14 . The remaining lifetime comparing section  227  compares the remaining body lifetime stored in the remaining body lifetime storing section  239  with the remaining battery lifetime stored in the remaining battery lifetime storing section  235 . 
     When the remaining lifetime of the body is shorter than the remaining lifetime of the storage battery (battery)  14 , the instruction section  228  instructs at least one of an activation of an unused function and an enhancement of a used function among a plurality of functions consuming the electric power of the mobile apparatus  1 . 
     The instruction section  228  has a function presenting portion  251 , a function determining portion  252 , and an instruction notifying portion  253 .

Here, the function presenting portion  251  may calculate a difference between the remaining lifetime of the storage battery (battery)  14  and the remaining lifetime of the body, and determine at least one candidate of a function to be activated and a function to be enhanced in accordance with the difference. Thereafter, the function presenting portion  251  causes the information terminal  3  (presentation device) to present the determined candidate. The function presenting portion  251  sends a list of the determined candidate to the information terminal  3 . 
     Further, the function presenting portion  251  may determine a priority degree of the presentation of at least one of a function to be activated and a function to be enhanced in accordance with the acquired at least one of the type, use mode, and use record of the mobile apparatus  1 . The function presenting portion  251  may cause the information terminal  3  (presentation device) to present at least one of an activation of an unused function and an enhancement of a used function in accordance with the determined priority degree.

Further, the communication part  21  receives a response to the presentation sent from the information terminal  3 . 
     The function determining portion  252  determines at least one of the function to be activated and the function to be enhanced on the basis of the response to the presentation. 
     The instruction notifying portion  253  sends to the mobile apparatus  1  via the communication part  21  a notification instructing the determined at least one of the activation of the function and the enhancement of the function.

     Subsequently, in Step S 12 , the battery load acquiring section  222  acquires the battery load data received by the communication part  21 . 
     Subsequently, in Step S 13 , the battery load acquiring section  222  stores in the charge and discharge history storing section  231  the number of charge and discharge cycles of the storage battery  14  included in the acquired battery load data. 
     Next, in Step S 14 , the battery load acquiring section  222  stores in the battery mechanical load history storing section  232  the number of shakings of the housing of the storage battery  14  included in the acquired battery load data. 
     Next, in Step S 15 , the remaining battery lifetime calculating section  224  acquires a history of the number of charge and discharge cycles of the storage battery  14  stored in the charge and discharge history storing section  231 . 
     Next, in Step S 16 , the remaining battery lifetime calculating section  224  calculates a chemical remaining battery lifetime of the storage battery  14  on the basis of the acquired history of the number of charge and discharge cycles. 
     Thereafter, in Step S 17 , the remaining battery lifetime calculating section  224  stores the calculated chemical remaining battery lifetime in the chemical remaining battery lifetime storing section  233 . 
     Thereafter, in Step S 18 , the remaining battery lifetime calculating section  224  acquires the number of shakings of the housing of the storage battery  14  stored in the battery mechanical load history storing section  232 . 
     Thereafter, in Step S 19 , the remaining battery lifetime calculating section  224  calculates the mechanical remaining battery lifetime of the storage battery  14  on the basis of the acquired number of shakings of the housing of the storage battery  14 . 
     Thereafter, in Step S 20 , the remaining battery lifetime calculating section  224  stores the calculated mechanical remaining battery lifetime in the mechanical remaining battery lifetime storing section  234 . 
     Subsequently, in Step S 21 , the remaining battery lifetime calculating section  224  calculates, as the remaining battery lifetime, one of the chemical remaining battery lifetime stored in the chemical remaining battery lifetime storing section  233  and the mechanical remaining battery lifetime stored in the mechanical remaining battery lifetime storing section  234  which is shorter than the other. 
     Subsequently, in Step S 22 , the remaining battery lifetime calculating section  224  stores the calculated remaining battery lifetime in the remaining battery lifetime storing section  235 . 
     Hereinafter, a process of calculating the remaining body lifetime in Embodiment 1 of the present disclosure will be described. 
       FIG.  6    is a flowchart showing a process of calculating a remaining body lifetime in Embodiment 1 of the present disclosure. 
     First, in Step S 31 , the body load sending control section  154  acquires from the memory  18  the number of shakings of the body of the mobile apparatus  1 . The number of shakings denotes a cumulative value of the number of shakings of the body from the production of the mobile apparatus  1  up to the present. The memory  18  stores the number of shakings of the body of the mobile apparatus  1 . The body load sending control section  154  acquires from the memory  18  the number of shakings of the body of the mobile apparatus  1  at a specific timing. The specific timing is, for example, every one minute or every ten minutes. 
     Thereafter, in Step S 32 , the body load sending control section  154  sends to the server  2  via the communication part  19  body load data concerning a load applied to the body of the electric mobile apparatus  1 . The body load data includes the number of shakings of the body of the mobile apparatus  1 . 
     Thereafter, in Step S 41 , the communication part  21  of the server  2  receives the body load data sent from the mobile apparatus  1 . 
     Thereafter, in Step S 42 , the body load acquiring section  221  acquires the body load data received by the communication part  21 . 
     Thereafter, in Step S 43 , the body load acquiring section  221  stores the number of shakings of the body of the mobile apparatus  1  included in the acquired body load data in the body mechanical load history storing section  238 . 
     Subsequently, in Step S 44 , the remaining body lifetime calculating section  223  acquires mobile apparatus basic information from the mobile apparatus basic information storing section  236 . The mobile apparatus basic information includes a type of the mobile apparatus  1 , a use mode of the mobile apparatus  1 , and a use record of the mobile apparatus  1 . 
     Thereafter, in Step S 45 , the remaining body lifetime calculating section  223  calculates an initial lifetime of the body of the mobile apparatus  1  on the basis of the type of the mobile apparatus  1 , the use mode of the mobile apparatus  1 , and the use record of the mobile apparatus  1  acquired from the mobile apparatus basic information storing section  236 . 
     Subsequently, in Step S 46 , the remaining body lifetime calculating section  223  stores the calculated initial lifetime of the body of mobile apparatus  1  in the initial body lifetime storing section  237 . 
     The processings from Steps S 44  to S 46  are required to be executed only in the first calculation of the remaining body lifetime, and may be omitted in the second or subsequent calculation of the remaining body lifetime. 
     Subsequently, in Step S 47 , the remaining body lifetime calculating section  223  acquires the initial lifetime of the body stored in the initial body lifetime storing section  237 , and acquires the history of the number of shakings of the body stored in the body mechanical load history storing section  238 . 
     Subsequently, in Step S 48 , the remaining body lifetime calculating section  223  calculates the remaining body lifetime on the basis of the acquired initial lifetime of the body and history of the number of shakings of the body. 
     Next, in Step S 49 , the remaining body lifetime calculating section  223  stores the calculated remaining body lifetime in the remaining body lifetime storing section  239 . 
     Hereinafter, the process of estimating a lifetime shortening effect of each of a plurality of functions in Embodiment 1 of the present disclosure will be described. 
       FIG.  7    is a flowchart showing a process of estimating a lifetime shortening effect of each of a plurality of functions in Embodiment 1 of the present disclosure. 
     First, in Step S 61 , the drive control section  151  of the mobile apparatus  1  executes an activation of an unused function or an enhancement of a used function to estimate a lifetime shortening effect. The drive control section  151  enhances, for example, the used function of controlling the acceleration among the functions consuming the electric power. 
     It may be appreciated that the drive control section  151  executes an activation of an unused function or an enhancement of a used function in a measurement mode suitable to obtain an actual value of electric power consumption. For example, it may be appreciated that the drive control section  151  receives a selection, by the driver, of a function to be activated or a function to be enhanced in the measurement mode, and executes the selected activation of a function or enhancement of a function. 
     Subsequently, in Step S 62 , the actual electric power consumption value measuring section  156  measures an electric power consumption in the case of activating an unused function, or an electric power consumption in the case of enhancing a used function. For example, the actual electric power consumption value measuring section  156  measures an electric power consumption in the case of enhancing the used function of controlling the acceleration. 
     Subsequently, in Step S 63 , the communication part  19  sends to the server  2  information to identify an activated function or an enhanced function, and the actual value of electric power consumption measured by the actual electric power consumption value measuring section  156 . 
     Thereafter, in Step S 71 , the communication part  21  of the server  2  receives the information to identify an activated function or an enhanced function and the actual value of electric power consumption sent from the mobile apparatus  1 . 
     Subsequently, in Step S 72 , the actual electric power consumption value acquiring section  225  acquires the information to identify an activated function or an enhanced function and the actual value of electric power consumption received by the communication part  21 . 
     Thereafter, in Step S 73 , the actual electric power consumption value acquiring section  225  stores in the actual electric power consumption value storing section  241  the information to identify an activated function or an enhanced function and the actual value of electric power consumption in association with each other. 
     Thereafter, in Step S 74 , the lifetime shortening effect estimating section  226  acquires from the electric power consumption storing section  240  the electric power consumption of the function activated or enhanced in the measurement of the actual value of electric power consumption, i.e., the function whose lifetime shortening effect is estimated. 
     Subsequently, in Step S 75 , the lifetime shortening effect estimating section  226  acquires from the actual electric power consumption value storing section  241  the actual value of electric power consumption of the function activated or enhanced in the measurement of the actual value of electric power consumption, i.e., the function whose lifetime shortening effect is estimated. 
     Subsequently, in Step S 76 , the lifetime shortening effect estimating section  226  corrects the electric power consumption of the function whose lifetime shortening effect is estimated using the actual value of electric power consumption of the function whose lifetime shortening effect is estimated. 
     Next, in Step S 77 , the lifetime shortening effect estimating section  226  stores the corrected electric power consumption in the electric power consumption storing section  240 . 
     Next, in Step S 78 , the lifetime shortening effect estimating section  226  estimates a lifetime shortening effect on the basis of the corrected electric power consumption. 
     Thereafter, in Step S 79 , the lifetime shortening effect estimating section  226  stores in the lifetime shortening effect storing section  242  the estimated lifetime shortening effect in association with the information to identify an activated function or an enhanced function. 
     The flow may return to Step S 61  when there is, after the storage of the lifetime shortening effect, a function whose lifetime shortening effect is still to be estimated among the functions. The processings from Step S 61  to Step S 79  may be repeated until lifetime shortening effects of all the functions are estimated. 
     Hereinafter, the process of comparing a remaining body lifetime with a remaining battery lifetime in Embodiment 1 of the present disclosure will be described. 
       FIG.  8    is a first flowchart showing a process of comparing the remaining body lifetime with the remaining battery lifetime in Embodiment 1 of the present disclosure.  FIG.  9    is a second flowchart showing a process of comparing the remaining body lifetime with the remaining battery lifetime in Embodiment 1 of the present disclosure. 
     First, in Step S 91 , the remaining lifetime comparing section  227  of the server  2  judges whether the current time coincides with a comparison start time at which the remaining body lifetime is compared with the remaining battery lifetime. The comparison start time is, for example, one specific time a month, or a maintenance start time of the mobile apparatus  1 . 
     Here, when it is judged that the current time does not coincide with the comparison start time (NO in Step S 91 ), the flow returns to Step S 91 , and the processing of judgement in Step S 91  is repeated until the current time coincides with the comparison start time. 
     On the other hand, when it is judged that the current time coincides with the comparison start time (YES in Step S 91 ), in Step S 92 , the remaining lifetime comparing section  227  acquires the remaining body lifetime stored in the remaining body lifetime storing section  239 . 
     Subsequently, in Step S 93 , the remaining lifetime comparing section  227  acquires the remaining battery lifetime stored in the remaining battery lifetime storing section  235 . 
     Subsequently, in Step S 94 , the remaining lifetime comparing section  227  compares the remaining body lifetime with the remaining battery lifetime, and judges whether the remaining body lifetime is shorter than the remaining battery lifetime. 
     Here, the flow returns to Step S 91  when it is judged that the remaining body lifetime is not shorter than the remaining battery lifetime, i.e., when it is judged that the remaining body lifetime is equal to or longer than the remaining battery lifetime (NO in Step S 94 ). 
     On the other hand, when it is judged that the remaining body lifetime is shorter than the remaining battery lifetime (YES in Step S 94 ), in Step S 95 , the function presenting portion  251  acquires the lifetime shortening effect of each function from the lifetime shortening effect storing section  242 . 
     Subsequently, in Step S 96 , the function presenting portion  251  acquires the mobile apparatus basic information from the mobile apparatus basic information storing section  236 . The mobile apparatus basic information includes a type of the mobile apparatus  1 , a use mode of the mobile apparatus  1 , and a use record of the mobile apparatus  1 . 
     Subsequently, in Step S 97 , the function presenting portion  251  calculates a difference between the remaining body lifetime and the remaining battery lifetime. 
     Thereafter, in Step S 98 , the function presenting portion  251  determines at least one candidate of a function to be activated and a function to be enhanced on the basis of the lifetime shortening effect, the mobile apparatus basic information, and the difference between the remaining body lifetime and the remaining battery lifetime. 
     Here, the function presenting portion  251  selects, among the functions, a function appropriate for the type of the mobile apparatus included in the mobile apparatus basic information. Thereafter, the function presenting portion  251  selects, among the selected functions, a function appropriate for a use mode. Specifically, in a certain use mode, the use of a function is permitted, whereas the use of another function is not permitted. Accordingly, the function presenting portion  251  further selects, among the selected functions, a function appropriate for the use mode. Thereafter, the function presenting portion  251  selects, among the selected functions, a function having a lifetime shortening effect shorter than a difference between the remaining body lifetime and the remaining battery lifetime. The function presenting portion  251  determines the selected function as a candidate. 
     Thereafter, in Step S 99 , the function presenting portion  251  determines a priority degree of the presentation of at least one of a function to be activated and a function to be enhanced in accordance with at least one of the type, use mode, and use record of the mobile apparatus  1  included in the mobile apparatus basic information. For example, the use record includes information indicating how the mobile apparatus  1  is used. In a mobile apparatus  1  where the headlamp  13  is turned on only few times, the function of increasing the luminance of the headlamp  13  has a lower priority degree. In a mobile apparatus  1  which is not accelerated to more than a predetermined speed, the function of enhancing the acceleration performance has a lower priority degree. A priority degree of each function may be determined in advance according to a type of the mobile apparatus or a use mode of the mobile apparatus. 
     Subsequently, in Step S 100 , the function presenting portion  251  sends to the information terminal  3  via the communication part  21  the function presenting information showing the list of the at least one candidate of a function to be activated and a function to be enhanced. 
     Thereafter, in Step S 111 , the communication part  31  of the information terminal  3  receives the function presenting information sent from the server  2 . 
     Thereafter, in Step S 112 , the function presentation control section  321  causes the display part  33  to display the function presenting information received by the communication part  31 . 
       FIG.  10    is an illustration showing exemplary function presenting information in Embodiment 1 of the present disclosure. 
     The display part  33  displays the function presenting information showing the list of the at least one candidate of a function to be activated and a function to be enhanced. When the mobile apparatus  1  is in the use mode where the mobile apparatus  1  is shared by the users, the function presenting information shown in  FIG.  10    is displayed. The function presenting portion  251  of the server  2  has selected the function of controlling the luminance, the function of performing communications, and the function of controlling the acceleration. Further, the function of controlling the luminance has the highest priority degree, the function of performing communications has the second highest priority degree, and the function of controlling the acceleration has the third highest priority degree. The function of controlling the luminance, the function of performing communications, and the function of controlling the acceleration are displayed in a descending order of priority degree. 
     Additionally, the function presenting information includes an electric power consumption in the case of enhancing the function of controlling the luminance, an electric power consumption in the case of activating the function of performing communications, and an electric power consumption in the case of enhancing the function of controlling the acceleration. The display part  33  may display the function of controlling the luminance, the function of performing communications, and the function of controlling the acceleration in a descending order of electric power consumption. Further, the function presenting information includes a checkbox  331  for receiving a selection by the manager of the at least one of a function to be activated and a function to be enhanced. When the checkbox  331  corresponding to a desired function is touched by the manager, the display part  33  causes a checkmark to be displayed in the checkbox  331 . 
       FIG.  11    is an illustration showing exemplary function presenting information in Modification 1 of Embodiment 1 of the present disclosure. 
     When the mobile apparatus  1  is in the use mode where the mobile apparatus  1  is shared by the employees of a company, the function presenting information shown in  FIG.  11    is displayed. The function presenting portion  251  of the server  2  has selected the function of controlling the luminance and the function of controlling the acceleration. Further, the function of controlling the luminance has the highest priority degree, and the function of controlling the acceleration has the second highest priority degree. The function of controlling the luminance and the function of controlling the acceleration are displayed in a descending order of priority degree. 
     Additionally, the function presenting information includes an electric power consumption in the case of enhancing the function of controlling the luminance and an electric power consumption in the case of enhancing the function of controlling the acceleration. The display part  33  may display the function of controlling the luminance and the function of controlling the acceleration in a descending order of electric power consumption. Further, the function presenting information includes a checkbox  331  for receiving a selection by the manager of a function to be enhanced. When the checkbox  331  corresponding to a desired function is touched by the manager, the display part  33  causes a checkmark to be displayed in the checkbox  331 . 
       FIG.  12    is an illustration showing exemplary function presenting information in Modification 2 of Embodiment 1 of the present disclosure. 
     When the mobile apparatus  1  is in the use mode where the mobile apparatus  1  is used by an individual user, the function presenting information shown in  FIG.  12    is displayed. The function presenting portion  251  of the server  2  has selected the function of controlling the luminance, the function of controlling the acceleration, and the function of supplying an electric power. Further, the function of controlling the luminance has the highest priority degree, the function of controlling the acceleration has the second highest priority degree, and the function of supplying an electric power has the third highest priority degree. The function of controlling the luminance, the function of controlling the acceleration, and the function of supplying an electric power are displayed in a descending order of priority degree. 
     Additionally, the function presenting information includes an electric power consumption in the case of enhancing the function of controlling the luminance, an electric power consumption in the case of enhancing the function of controlling the acceleration, and an electric power consumption in the case of activating the function of supplying an electric power. The display part  33  may display the function of controlling the luminance, the function of controlling the acceleration, and the function of supplying an electric power in a descending order of electric power consumption. Further, the function presenting information includes a checkbox  331  for receiving a selection by the manager of at least one of a function to be activated and a function to be enhanced. When the checkbox  331  corresponding to a desired function is touched by the manager, the display part  33  causes a checkmark to be displayed in the checkbox  331 . 
     Referring again to  FIG.  9   , next, in Step S 113 , the function presentation control section  321  receives a selection by the manager of a function. The manager selects at least one of a function to be activated and a function to be enhanced using the input part  34 . Although a plurality of functions is selectable, when a sum of the lifetime shortening effects of the plurality of functions is greater than a difference between the remaining body lifetime and the remaining battery lifetime, the function presentation control section  321  rejects the selection of the plurality of functions, and when a sum of the lifetime shortening effects of the plurality of functions is equal to or smaller than the difference between the remaining body lifetime and the remaining battery lifetime, the function presentation control section  321  receives the selection of the plurality of functions. 
     Subsequently, in Step S 114 , the response control section  322  sends to the server  2  via the communication part  31  response information to identify the selected function. 
     Thereafter, in Step S 101 , the communication part  21  of the server  2  receives the response information sent from the information terminal  3 . 
     Thereafter, in Step S 102 , the function determining portion  252  determines at least one of the function to be activated and the function to be enhanced on the basis of the response information. 
     Thereafter, in Step S 103 , the instruction notifying portion  253  sends to the mobile apparatus  1  via the communication part  21  a notification instructing the at least one of the activation of the function and the enhancement of the function which is determined by the function determining portion  252 . 
     Subsequently, in Step S 121 , the communication part  19  of the mobile apparatus  1  receives the notification sent from the server  2 . 
     Subsequently, in Step S 122 , the drive control section  151  executes at least one of the activation of an unused function and the enhancement of a used function in accordance with the notification received by the communication part  19 . 
     In this Embodiment 1, when the remaining lifetime of the body is shorter than the remaining lifetime of the battery, at least one of an activation of an unused function and an enhancement of a used function among a plurality of functions consuming the electric power of the mobile apparatus  1  is instructed. Therefore, the remaining lifetime of the storage battery  14  of the mobile apparatus  1  can be made to approach the remaining lifetime of the body of the mobile apparatus  1 . This can consequently prevent a disposal of the storage battery  14  still having a lifetime together with the body having no lifetime. Further, the activation of an unused function or the enhancement of a used function can increase the convenience for the driver. In other words, the remaining lifetime of the storage battery  14  of a mobile apparatus  1  can be made to approach the remaining lifetime of the body of the mobile apparatus  1  by efficiently consuming the lifetime of the storage battery  14  of the mobile apparatus  1 . 
     In this Embodiment 1, the server  2  sends to the mobile apparatus  1  a notification instructing the determined at least one of the activation of the function and the enhancement of the function, but the present disclosure is not particularly limited thereto. The information terminal  3  may send to the mobile apparatus  1  a notification instructing the determined at least one of the activation of the function and the enhancement of the function. 
     Embodiment 2 
     In Embodiment 1 above, the function presenting portion  251  causes the information terminal  3  to present at least one of an activation of an unused function and an enhancement of a used function. On the other hand, in Embodiment 2, at least one of an activation of an unused function and an enhancement of a used function is not presented on the information terminal  3 , at least one of an activation of an unused function and an enhancement of a used function is determined, and a notification instructing the determined at least one of the function to be activated and the function to be enhanced is sent to the mobile apparatus  1 . 
       FIG.  13    is a diagram showing a general configuration of an information processing system according to Embodiment 2 of the present disclosure. 
     An information processing system shown in  FIG.  13    includes a mobile apparatus  1  and a server  2 A. The information processing system in Embodiment 2 is not provided with an information terminal  3 . In this Embodiment 2, the same constituent elements as those of Embodiment 1 will be allotted with the same reference numerals, and the description thereof will be omitted. 
     The server  2 A is, for example, a web server. The server  2 A receives various information from the mobile apparatus  1 , and sends various information to the mobile apparatus  1 . The server  2 A calculates a remaining lifetime of the body of the mobile apparatus  1 , and calculates a remaining lifetime of the battery. Thereafter, the server  2 A compares the remaining lifetime of the body with the remaining lifetime of the battery, and instructs, when the remaining lifetime of the body is shorter than the remaining lifetime of the battery, at least one of an activation of an unused function and an enhancement of a used function among a plurality of functions consuming the electric power of the mobile apparatus  1 . The server  2 A is mutually communicably connected to the mobile apparatus  1  via the network  4 . 
       FIG.  14    is a diagram showing an exemplary configuration of a server according to Embodiment 2 of the present disclosure. 
     The server  2 A shown in  FIG.  14    includes a communication part  21 , a processor  22 A, and a memory  23 . 
     The processor  22 A is, for example, a CPU. The processor  22 A furnishes a body load acquiring section  221 , a battery load acquiring section  222 , a remaining body lifetime calculating section  223 , a remaining battery lifetime calculating section  224 , an actual electric power consumption value acquiring section  225 , a lifetime shortening effect estimating section  226 , a remaining lifetime comparing section  227 , and an instruction section  228 A. 
     When the remaining lifetime of the body is shorter than the remaining lifetime of the storage battery (battery)  14 , the instruction section  228 A instructs at least one of an activation of an unused function and an enhancement of a used function among a plurality of functions consuming the electric power of the mobile apparatus  1 . 
     The instruction section  228 A has a difference calculating portion  254 , a function determining portion  252 A, and an instruction notifying portion  253 A. 
     The difference calculating portion  254  calculates a difference between the remaining lifetime of the storage battery (battery)  14  and the remaining lifetime of the body. 
     The function determining portion  252 A determines at least one of the function to be activated and the function to be enhanced on the basis of the difference calculated by the difference calculating portion  254 . The function determining portion  252 A calculates a reduction of the remaining lifetime of the storage battery  14  due to the activation of an unused function on the basis of an electric power consumption in the case of activating the unused function. Further, the function determining portion  252 A calculates a reduction of the remaining lifetime of the storage battery  14  due to the enhancement of a used function on the basis of an electric power consumption in the case of enhancing the used function. The function determining portion  252 A determines at least one of a function to be activated and a function to be enhanced in such a manner that at least one of a reduction of the remaining lifetime of the storage battery  14  due to the activation of an unused function and a reduction of the remaining lifetime of the storage battery  14  due to the enhancement of a used function is kept from exceeding a difference between the remaining lifetime of the storage battery  14  and the remaining lifetime of the body. 
     The instruction notifying portion  253 A instructs the at least one of the activation of the function and the enhancement of the function which is determined by the function determining portion  252 A. 
     Since the process of calculating the remaining battery lifetime, the process of calculating the remaining body lifetime, and the process of estimating respective lifetime shortening effects of the functions in Embodiment 2 of the present disclosure are the same as those in Embodiment 1, the description thereof will be omitted. 
     Hereinafter, the process of comparing a remaining body lifetime with a remaining battery lifetime in Embodiment 2 of the present disclosure will be described. 
       FIG.  15    is a flowchart showing a process of comparing a remaining body lifetime with a remaining battery lifetime in Embodiment 2 of the present disclosure. 
     Since the processings from Steps S 131  to S 134  are the same as the processings from Steps S 91  to S 94  shown in  FIG.  8   , the description thereof will be omitted. 
     When it is judged that the remaining body lifetime is shorter than the remaining battery lifetime (YES in Step S 134 ), in Step S 135 , the difference calculating portion  254  calculates a difference between the remaining body lifetime and the remaining battery lifetime. 
     Thereafter, in Step S 136 , the function determining portion  252 A acquires the lifetime shortening effect of each function from the lifetime shortening effect storing section  242 . 
     Subsequently, in Step S 137 , the function determining portion  252 A acquires the mobile apparatus basic information from the mobile apparatus basic information storing section  236 . The mobile apparatus basic information includes a type of the mobile apparatus  1 , a use mode of the mobile apparatus  1 , and a use record of the mobile apparatus  1 . 
     Thereafter, in Step S 138 , the function determining portion  252 A determines at least one of a function to be activated and a function to be enhanced on the basis of the lifetime shortening effect, the mobile apparatus basic information, and the difference between the remaining body lifetime and the remaining battery lifetime. 
     Here, the function determining portion  252 A selects, among the functions, a function appropriate for the type of the mobile apparatus included in the mobile apparatus basic information. Thereafter, the function determining portion  252 A selects, among the selected functions, a function appropriate for a use mode. Specifically, in a certain use mode, the use of a function is permitted, whereas the use of another function is not permitted. Accordingly, the function determining portion  252 A further selects, among the selected functions, a function appropriate for the use mode. Thereafter, the function determining portion  252 A determines, among the selected functions, a function having a lifetime shortening effect shorter than a difference between the remaining body lifetime and the remaining battery lifetime as the at least one of a function to be activated and a function to be enhanced. When there is a plurality of functions having respective lifetime shortening effects shorter than the difference between the remaining body lifetime and the remaining battery lifetime, the function determining portion  252 A may determine a function having the greatest lifetime shortening effect. 
     Further, the function determining portion  252 A may determine a priority degree of at least one of a function to be activated and a function to be enhanced in accordance with at least one of the type, use mode, and use record of the mobile apparatus  1  included in the mobile apparatus basic information. When there is a plurality of functions having respective lifetime shortening effects shorter than the difference between the remaining body lifetime and the remaining battery lifetime, the function determining portion  252 A may determine a function having the highest priority degree among the functions as the function to be activated or the function to be enhanced. 
     Thereafter, in Step S 139 , the instruction notifying portion  253 A sends to the mobile apparatus  1  via the communication part  21  a notification instructing the at least one of the activation of the function and the enhancement of the function which is determined by the function determining portion  252 A. 
     Subsequently, in Step S 141 , the communication part  19  of the mobile apparatus  1  receives the notification sent from the server  2 A. 
     Subsequently, in Step S 142 , the drive control section  151  executes at least one of the activation of the unused function and the enhancement of the used function in accordance with the notification received by the communication part  19 . 
     In this Embodiment 2, at least one of the function to be activated and the function to be enhanced is automatically instructed, thereby allowing the mobile apparatus  1  to automatically execute the instructed at least one of the activation of the function and the enhancement of the function.
