     DESCRIPTION OF EMBODIMENTS 
     To begin with, a relevant technology will be described first only for understanding the following embodiments. 
     As a result of detailed studies by the inventors, a problem was found in the above-described technology that unnecessary energy is used in a state where a user is not in the vehicle when an autonomous vehicle moves in a parking lot without consideration for the vehicle moving in a state where the user is not in the vehicle. 
     According to one aspect of the present disclosure, an electrical component control device can reduce the unnecessary energy used when the autonomous vehicle moves in the parking lot. 
     A first aspect of the present disclosure is an electrical component control device that controls an operation of at least one electrical component mounted in an autonomous vehicle. The electrical component control device includes: a request determination unit configured to determine whether a movement request for moving the autonomous vehicle without a user in the autonomous vehicle is received; an operation restraining unit configured to restrain operations of a plurality of target electrical components that act on five senses of the user when the autonomous vehicle is instructed to move in response to the movement request; an operation state recording unit configured to record, in a memory, operation states of the target electrical components at a timing the operation restraining unit restrains the operations of the target electrical components; and a state restoring unit configured to, after the operation restraining unit restrained the operations of the target electrical components, restore the target electrical components to the operation states recorded in the memory before the user gets on the autonomous vehicle. 
     According to such a configuration, since an operation of the target electrical components is restrained when the autonomous vehicle travels without the user, it is possible to reduce a use of the unnecessary energy during the move of the autonomous vehicle. 
     A second aspect of the present disclosure is an in-vehicle electrical component control device that controls an operation state of at least one electrical component mounted in an autonomous vehicle. The in-vehicle electrical component control device includes: an operation restraining unit configured to restrain operations of a plurality of target electrical components that act on five senses of a user when the autonomous vehicle is instructed to move in response to a movement request for the autonomous vehicle to perform automatic valet parking to move between a getting on-off area and a parking area in a parking lot without the user in the autonomous vehicle; an operation state recording unit configured to record, in a memory, operation states of the target electrical components at a timing the operation restraining unit restrains the operations of the target electrical components; and a state restoring unit configured to, after the operation restraining unit restrained the operations of the target electrical components, restore the target electrical components to the operation states recorded in the memory before the user gets on the autonomous vehicle. The operation restraining unit is configured to, when the automatic valet parking is performed, switch the target electrical components to a restraining mode in which the operations of the target electrical components are restrained in a more restrictive manner than before the automatic valet parking is performed. 
     A third aspect of the present disclosure is an electrical component control device that controls an operation of at least one electrical component mounted in an autonomous vehicle. The electrical component control device includes: at least one processor programmed to: determine whether a movement request for moving the autonomous vehicle without a user in the autonomous vehicle is received; restrain operations of a plurality of target electrical components that act on five senses of the user when the autonomous vehicle is instructed to move in response to the movement request; record, in a memory, operation states of the target electrical components at a timing of restraining the operations of the target electrical components; and after restraining the operations of the target electrical components, restore the target electrical components to the operation states recorded in the memory before the user gets on the autonomous vehicle. 
     Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. 
     1. Embodiments 
     1-1. Configuration of Parking Assistance System  1   
     A configuration of a parking assistance system  1  will be described with reference to  FIGS.  1  to  3   . As shown in  FIG.  1   , the parking assistance system  1  includes a vehicle entering chamber  3  set as a getting-off area, which is a region where a user gets off, a vehicle exiting chamber  5  set as a getting-on area, which is a region where the user gets on, and a parking area  7 . Hereinafter, the region including the vehicle entering chamber  3 , the vehicle exiting chamber  5 , and the parking area  7  will also be referred to as a parking lot. The vehicle entering chamber  3  and the vehicle exiting chamber  5  are collectively referred to as a getting on-off area 3.5. 
     Multiple sections are provided in each of the vehicle entering chamber  3  and the vehicle exiting chamber  5 .

The control unit  47  may include one microcomputer or multiple microcomputers 
     The control unit  47  includes a configuration for transmitting the guide route to the parking position and a parking start instruction to the autonomous vehicle  18  and a configuration for controlling operation states of electrical components  77  and  79 .

     The memory  53  stores map information of the parking lot. The map information includes information indicating a state of the section in the parking area  7 . As the state of the section, there are an empty state (hereinafter referred to as an empty state) and a state occupied by the autonomous vehicle  18  (hereinafter referred to as an occupied state). The communication unit  49  can communicate with the autonomous vehicle  18 . 
     The infrastructure  41  has a function of acquiring information (hereinafter referred to as in-parking lot information) representing an internal situation of the parking assistance system  1  and supplying the in-parking lot information to the management device  39 . 
     Examples of the in-parking lot information include information representing a position of an obstacle, information representing the state of a section in the parking area  7 , and position information of the autonomous vehicle  18  existing in the parking assistance system  1 . 
     The fixed term inal device  43  is installed in the vicinity of the vehicle entering chamber  3  as shown in  FIG.  1   . The fixed terminal device  43  includes a control unit  43 A, a communication unit  43 B, an input unit  43 C, a display unit  43 D, and a reading unit  43 E. The vicinity of the vehicle entering chamber  3  represents a getting-off area, that is, the inside of the vehicle entering chamber  3  or its surroundings, and a range within which the user can quickly return to the vehicle entering chamber without making other users wait. 
     The control unit  43 A receives an input operation by the occupant and outputs a signal in response to the input operation to the management device  39 .

     The control unit  43 A includes a microcomputer having a CPU  431  and a semiconductor memory such as RAM or ROM (hereinafter referred to as a memory  432 ). For example, the control unit  43 A outputs a parking request signal in response to the input operation to the input unit  43 C. 
     The parking request signal is a signal for requesting that the autonomous vehicle  18  is parked by moving the autonomous vehicle  18  in the vehicle entering chamber  3  to the parking area  7 . When the signal in response to the input operation is output to the management device  39 , the fixed terminal device  43  outputs identification information of the autonomous vehicle  18  and the like.

The control unit  45 A includes a microcomputer having a CPU  451  and a semiconductor memory such as RAM or ROM (hereinafter referred to as memory  452 ). 
     The mobile terminal device  45  is a device possessed by the occupant of the autonomous vehicle  18 , and is configured to communicate with the management device  39  using the communication unit  45 B. The mobile terminal device  45  is configured as a smartphone, for example. The user can input instructions using the input unit  45 C. 
     The notification unit  45 D is configured as a display and a speaker, and notifies the occupant a command from the control unit  45 A with an image or voice. 
     As described above, the autonomous vehicle  18  has an automatic valet parking function. As shown in  FIG.  2   , the autonomous vehicle  18  includes a control unit  69 , a sensor group  71 , a position information acquisition unit  73 , a communication unit  75 , a target electrical component  77 , and a specific electrical component  79 . 
     The control unit  69  includes a microcomputer including a CPU  691  and, for example, a semiconductor memory (hereinafter referred to as a memory  692 ) such as a RAM or a ROM. The control unit  69  controls each unit of the autonomous vehicle  18 . The control unit  69  performs control to realize the function of autonomous driving. The autonomous vehicle  18  acquires the map information and the guide route of the parking lot from the management device  39 , and uses the map information and the guide route of the parking lot when performing the autonomous driving. 
     The sensor group  71  acquires peripheral information representing a situation around the autonomous vehicle  18 . An example of contents of the peripheral information includes a position of an obstacle existing around the autonomous vehicle  18 . The sensor group  71  includes, for example, a camera, a lidar, and the like. The autonomous vehicle  18  uses the peripheral information when performing the autonomous driving. 
     The position information acquisition unit  73  acquires the position information of the autonomous vehicle  18 . The position information acquisition unit  73  is, for example, a position estimation system using a lidar and a map. The autonomous vehicle  18  uses the position information when performing the autonomous driving. The communication unit  75  can communicate with the management device  39 . 
     The target electrical component  77  is a preset device among the devices of the autonomous vehicle  18  that acts on the five senses of the user. The five senses of the user represent any of the user’s senses of sight, hearing, touch, smell, and taste. Here, the target electrical component  77  includes at least one of a device that can be visually recognized by the user from inside the vehicle and an accessory device. Examples of the device that can be visually recognized by the user from inside the vehicle include a car navigation apparatus (hereinafter referred to as a car navigation system), an electrical component that presents information to the user, such as an instrument panel meter, an interior light, and a hazard flasher. The accessory device is a device for control turn-on/off of power by an accessory switch, and examples thereof include an audio and a cigarette lighter. The accessory devices are devices that are highly unlikely to be directly involved in traveling of the vehicle, and many of them are devices that act on the five senses of the user. 
     Alternatively, the target electrical component  77  may be a device capable of instructing turn-on/off control of the power by the control unit  69  of the autonomous vehicle  18 . 
     The specific electrical component  79  is a predetermined device among the devices other than the target electrical component  77 , and is an electrical component necessary for the autonomous driving function or an electrical component that contributes to user’s comfort.

Among the specific electrical components  79 , electrical components that contribute to user’s comfort include air conditioners, air cleaners, seat heaters, steering heaters, and the like. In the process to be described later, as an operation state of the air conditioner, a set temperature, a distinction of an inside air circulation and outside air circulation, and the like are controlled. 
     The functions that act on the five senses of the user may be restrained, even in the functions of electrical components that are necessary for the autonomous driving function. For example, a warning sound from a millimeter wave radar or an ultrasonic sensor may be restrained in an AVP mode, which will be described later. 
     1-2. Process 
     11. Parking Setting Process Executed by Management Device  39   
     A parking setting process executed by the management device  39  will be described with reference to  FIG.  4   . The parking setting process is, for example, a process that is started when the power of the management device  39  is turned on and then repeatedly executed. Hereinafter, a process executed by the control unit  47  (particularly the CPU  51 ) of the management device  39  is also referred to as the process executed by the management device  39 . 
     The request determination unit  47 A of the management device  39  determines whether the parking request signal has been received in step (hereinafter referred to as “S”)  11  of the parking setting process shown in  FIG.  4   . The parking request signal is one of movement requests to move the autonomous vehicle  18  in a state where on the user is not in the vehicle. 
     In this case, when a user such as an occupant of the autonomous vehicle  18  operates the fixed terminal device  43  to input a parking request, the fixed terminal device  43  transmits a parking request signal corresponding to this input to the management device  39 . At this time, the user inputs vehicle information such as a number plate for specifying a vehicle, user information such as a user ID and a password for specifying the user, and other necessary types of information, to the fixed terminal device  43 . After the operation of the parking request, the user can leave the parking lot and head for the destination. 
     In S 11 , when the request determination unit  47 A determines that the parking request signal has not been received, S 11  is repeated. When it is determined in S 11  that the parking request signal has been received, the management device  39  transmits an IGON instruction for instructing to turn on the power of the vehicle, such as the ignition, to the autonomous vehicle  18  in S 101 . 
     Subsequently, in S 102 , the management device  39  requests the autonomous vehicle  18  to transmit a vehicle state. The vehicle state herein includes operation states of the target electrical component  77  and the specific electrical component  79  and a surrounding environment of the autonomous vehicle  18 . The surrounding environment is information such as illuminance, temperature, and weather around the autonomous vehicle  18 . 
     Subsequently, in S 103 , the operation state recording unit  47 C of the management device  39  acquires the requested vehicle state from the autonomous vehicle  18  and records the vehicle state in the memory  53 . That is, when attempting to restrain the operation, in detail, immediately before the vehicle moves from the vehicle entering chamber  3 , the operation state recording unit  47 C records the operation states of the target electrical component  77  and the specific electrical component  79  in the memory  53 . The operation states of the target electrical component  77  and the specific electrical component  79  recorded in the memory  53  are a normal mode, which will be described later. For example, the operation state of each electrical component in the normal mode is the operation state of each electrical component immediately before the user turns off the ignition in the vehicle entering chamber  3 . 
     The vehicle state includes operation states of individual target electrical components  77  and specific electrical components  79 . In the operation state, for example, whether the power for each electrical component is turned off or on, and when the power is turned on, a lamp includes illuminance and color thereof, the air conditioner includes the set temperature, the air volume, the blowing port position, and the distinction of the inside air circulation air or outside air circulation, and the like. 
     Subsequently, in S 104 , the state setting unit  47 E of the management device  39  sets the state of the target electrical component  77  at the time of shift to the AVP mode according to the vehicle state, setting by the user, and the surrounding environment. The AVP mode is a restraining mode of the present disclosure, and is a mode of restraining the operation state of the target electrical components  77  with the operation of the target electrical component  77 , which is more than before the automatic valet parking is performed, when the automatic valet parking is performed. The setting of the operation state in the AVP mode is recorded in the memory  53  for each target electrical component  77 . As a specific configuration for restraining the operation, for example, a configuration in which the management device  39  allows the target electrical component  77  to be in a waiting state, or a configuration in which the power of the target electrical component  77  is turned on when it can be restored to be turned on even if the power of the target electrical component  77  is turned off, can be adopted. 
     More specifically, in the AVP mode, multimedia devices, such as an air conditioner and an audio, are turned off. Drawing on the car navigation system or instrument panel is stopped, or an image or message is displayed indicating that the vehicle is automatically driven in the AVP mode. 
     In this case, for example, the state setting unit  47 E is set to restrain an operation of the target electrical component  77  registered in advance as a device for restraining the operation during the AVP mode, such as turning off the power of the target electrical component  77 , which is a lamp that assists a user’s field of view. However, the state setting unit  47 E changes the setting by the user, and a content set as the AVP mode when the setting needs to be changed according to the surrounding environment. 
     The other-device control unit  47 G of the management device  39  sets a state of the specific electrical component  79  when shifting to the AVP mode. The other-device control unit  47 G performs settings for controlling at least one of a setting for an air conditioner, a setting for inside air circulation, setting for outside air circulation, and an operation state of the accessory. 
     In this case, the user can set the operation states of the target electrical component  77  and the specific electrical component  79  input by the mobile terminal device  45 . The setting made by the user should be mainly reflected at the time of exiting the vehicle, but may be reflected at the time of parking depending on a selection of the user. For example, the user can set the air conditioner to continue operating while the autonomous vehicle  18  is traveling in the AVP mode. When the setting is made by the user, contents set as the AVP mode is overwritten with a content set by the user. 
     The setting of the operation states of the target electrical component  77  and the specific electrical component  79  to be reflected during the exiting of the vehicle is referred to as a vehicle-exiting setting. In S 103 , the operation states of the target electrical component  77  and the specific electrical component  79  are recorded in the memory  53  as a normal mode. When the vehicle-exiting setting is set in S 104 , the normal mode recorded in S 103  may be changed to the normal mode reflecting the setting for exiting the vehicle. 
     The setting for exiting the vehicle can be set any time before the operation states of the target electrical component  77  and the specific electrical component  79  are returned to the normal mode by the state restoring unit  47 D of the management device  39 . Hereinafter, an example in which the vehicle-exiting setting is performed after the user gets off the vehicle will be described. 
       FIG.  8    is an example of a configuration of a screen of the vehicle-exiting setting, displayed on the display unit  43 D of the fixed terminal device  43 . The vehicle-exiting setting during the waiting time is made because it takes several minutes for the autonomous vehicle  18  to arrive at the vehicle exiting chamber  5  from a parking position. For example, after the user operates the fixed terminal device  43  to make a vehicle exiting request, the screen of  FIG.  8    is displayed. The user can set whether the air conditioner is turned on, and further set a temperature and an air volume. The user can set a destination for a car navigation system, such as a home or facility, by operating the fixed terminal device  43 . Further, the user can set an operation of multimedia and play a DVD concurrently with getting on the vehicle. 
       FIG.  9    is an example of a configuration of a screen for air conditioner setting displayed on the screen of the mobile terminal device  45  of the user. After the user gets out of the autonomous vehicle  18  and transmits a parking request signal to the management device  39  via the fixed terminal device  43  or the mobile terminal device  45 , the operation state of the air conditioner at the time of exiting the vehicle can be set until the autonomous vehicle  18  arrives at the vehicle exiting chamber  5 . For example, even when the user gets off the vehicle without operating the air conditioner during the entering of the vehicle, the mobile terminal device  45  can be operated to set the air conditioner to operate at the time of exiting the vehicle while shopping at the facility. The user can set operation states of a steering heater and a seat heater at the time of exiting the vehicle. 
     Since the operation states of the target electrical components  77  and the specific electrical components  79  in the normal mode are recorded in the memory  53  of the management device  39 , the operation states of the target electrical component  77  and the specific electrical component  79  at the time of exiting the vehicle can be set even when ignition of the autonomous vehicle  18  is in an off-state. 
     The operation setting unit  47 F sets the operation state of the target electrical component  77  according to the surrounding environment of the autonomous vehicle  18 , in other words, an environment in the parking lot. For example, when the autonomous vehicle  18  has insufficient illuminance for autonomous driving, the headlight is turned on. Alternatively, when raindrops cause obscurity of an image of surroundings captured by a camera, a wiper is operated. In this manner, the operation setting unit  47 F maintains a function necessary for traveling and stops a function necessary for the user’s comfort, for example. 
     The surrounding environment of the autonomous vehicle  18  is acquired by, for example, an illuminance sensor or a raindrop sensor of the sensor group  71 . Alternatively, the surrounding environment of the autonomous vehicle  18  is acquired by an illuminance sensor or a raindrop sensor of the infrastructure  41 . The operation setting unit  47 F issues an instruction to turn on the headlight to the autonomous vehicle  18  when the illuminance in the parking lot is below a reference value. 
     Subsequently, in S 105 , the management device  39  transmits an AVP mode shift instruction, which is an instruction to shift to the AVP mode, to the autonomous vehicle  18 . 
     Subsequently, the management device  39  transmits the map information of the parking lot to the autonomous vehicle  18  in S 12 . That is, when an input indicating the start of parking is performed by the user with the fixed terminal device  43 , the management device  39  transmits the map information of the parking lot to the autonomous vehicle  18 . 
     The autonomous vehicle  18  that has received the map information is set to return position information as described later. Thus, the management device  39  receives the position information transmitted from the autonomous vehicle  18  in S 13 . Subsequently, the process proceeds to S 14 , and the management device  39  performs an autonomous vehicle entering process. The autonomous vehicle entering process is a process of moving the autonomous vehicle  18  to the parking position. 
     The autonomous vehicle entering process ends when the parking position is set, the guide route from a current location of the autonomous vehicle  18  to the parking position is set, the autonomous vehicle  18  is traveled according to the guide route, and a notification that the autonomous vehicle  18  arrived at the parking position has been parked is received. 
     When the autonomous vehicle entering process ends, the management device  39  ends the parking setting process. 
     12. Automatic Parking Process Executed by Autonomous Vehicle  18   
     The automatic parking process executed by the autonomous vehicle  18  will be described with reference to  FIG.  5   . The automatic parking process starts when an IGON instruction is received in the parking setting process executed by the management device  39 . The automatic parking process is a process in which the autonomous vehicle  18  performs autonomous driving from the vehicle entering chamber  3  to the parking position. Hereinafter, a process executed by the control unit  69  of the autonomous vehicle  18  will also be referred to as a process executed by the autonomous vehicle  18 . 
     In the automatic parking process, first, the power, such as ignition, of the autonomous vehicle  18  is turned on in S 111 . Subsequently, in S 112 , the autonomous vehicle  18  determines whether a vehicle state is requested from the management device  39 . 
     The autonomous vehicle  18  returns to S 112  when it is determined in S 112  that no vehicle state is requested. On the other hand, when it is determined in S 112  that the vehicle state is been requested, the autonomous vehicle  18  proceeds to S113, acquires the vehicle state, and transmits the vehicle state to the management device  39 . That is, the autonomous vehicle  18  records the operation states of the target electrical component  77  and the specific electrical component  79  in the memory  53  of the management device  39  by transmitting the operation states of the target electrical component  77  and the specific electrical component  79  to the management device  39 . The control unit  69  may record the vehicle state transmitted to the management device  39 , here, the operation states of the target electrical component  77  and the specific electrical component  79  immediately before moving from the vehicle entering chamber  3 , in the memory  692  of the autonomous vehicle  18 . 
     Subsequently, in S 114 , the autonomous vehicle  18  determines whether there is the AVP mode shift instruction. When the autonomous vehicle  18  determines in S 114  that there is no AVP mode shift instruction, the process returns to S 114 . 
     On the other hand, when the autonomous vehicle  18  determines in S 114  that there is the AVP mode change instruction, the process proceeds to S 115 , and the autonomous vehicle  18  shifts from the normal mode to the AVP mode. In the AVP mode, the operation states of the electrical components  77  and  79  are changed to states set by the management device  39 . That is, when the specific electrical component  79  that has not been operated before the change to the AVP mode is set to operate during the AVP mode in the process of S 104 , the specific electrical component  79  shifts to a state of operating the specific electrical component  79  in the process of S 115 . The process of S 115  corresponds to a specific operation unit in the present disclosure. 
     Subsequently, the autonomous vehicle  18  determines whether the communication unit  75  has received the map information of the parking lot in S 40 . When the map information has not been received, the process returns to S 40 . 
     When the map information has been received, the process proceeds to S 41 , and the autonomous vehicle  18  estimates the current location of the autonomous vehicle  18 . In S 42 , the autonomous vehicle  18  transmits the estimation result of the current location to the management device  39  as position information of the autonomous vehicle  18 . 
     Subsequently, in S 46 , the autonomous vehicle  18  determines whether the guide route information has been received. The guide route information is transmitted by the management device  39 . In S 46 , when the guide route information has not been received, the process returns to S 46 . 
     In S 46 , when the guide route information has been received, the autonomous vehicle  18  starts autonomous driving of the autonomous vehicle  18  in S 52 . When the autonomous vehicle  18  performs autonomous driving, the autonomous vehicle  18  travels in accordance with the guide route included in the guide route information. 
     Subsequently, the autonomous vehicle  18  continues the autonomous driving of the autonomous vehicle  18  in S 55 . In this case, the autonomous vehicle  18  repeatedly transmits the position information of the autonomous vehicle  18  to the management device  39  until it is determined in S 57  that the parking has been completed, which will be described later. The transmitted position information is received by the management device  39 . 
     Then, in S 57 , the autonomous vehicle  18  determines whether the parking has been completed. The completion of the parking means that the autonomous vehicle  18  has arrived at the parking position set in the management device  39 . When the parking position is set to the target position, and the target position is then changed, the autonomous vehicle  18  determines that the parking has been completed even when the autonomous vehicle  18  arrives at a new target position after the change. When parking is not completed, the process returns to S 55 . 
     When parking has been completed, the process proceeds to S 58 , and the autonomous vehicle  18  transmits a parking completion notification by using the communication unit  75 . Subsequently, in S 119 , the power of the autonomous vehicle  18 , such as ignition, is turned off, and ends the process. The management device  39  receives the transmitted parking completion notification. 
     The infrastructure  41  may monitor the autonomous vehicle  18  that has completed parking and is parked in the parking area  7 . The management device  39  may receive information from the infrastructure  41 , and determine an abnormal vehicle when the autonomous vehicle  18  is detected while tuning on an interior light to notify the abnormal vehicle of an operator of the parking lot. 
     13. Vehicle Unentering Setting Process Executed by Management Device  39   
     A vehicle exiting setting process executed by the management device  39  will be described with reference to  FIG.  6   . The vehicle exiting setting process is a process of moving the autonomous vehicle  18  from the parking position to the vehicle exiting chamber  5  by self-traveling of the autonomous vehicle  18 . 
     The vehicle exiting setting process is a process repeatedly executed by the management device  39 , for example, in parallel with other processes. For example, when multiple autonomous vehicles  18  exist in the parking lot, the vehicle exiting setting process for one of the autonomous vehicles  18  is performed in parallel with a vehicle exiting setting process for the other autonomous vehicle  18  or the parking setting process, the vehicle entering process, and the vehicle exiting process. In the vehicle exiting setting process, first, the management device  39  determines whether a vehicle exiting request signal has been received in S 61 . The fixed terminal device  43  transmits the vehicle exiting request signal, for example. 
     When there is no vehicle exiting request signal in S 61 , the process repeats S 61 . When there is the vehicle exiting request signal in S 61 , the management device  39  transmits the IGON instruction to the autonomous vehicle  18  in S 121 . This process is the same as S 101  described above. Subsequently, in S 122 , the management device  39  instructs the autonomous vehicle  18  to set for exiting the vehicle. The setting for exiting the vehicle is the setting at the time of exiting of the vehicle from among the settings according to input by the user using the mobile terminal device  45  in S 104 . For example, when the air conditioner is turned off when the user gets off the vehicle, but when the user desires that the air conditioner is turned on when the user gets on the vehicle, the user can set the air conditioner to be turned on in advance by using the mobile terminal device  45 . The vehicle-exiting setting is transmitted to the autonomous vehicle  18  before the autonomous vehicle  18  starts moving for exiting the vehicle, an internal space of the autonomous vehicle  18  can be made comfortable until the autonomous vehicle  18  arrives at the vehicle exiting chamber  5 . 
     Subsequently, the management device  39  receives the position information transmitted from the autonomous vehicle  18  in S 62 . Subsequently, the management device  39  performs an autonomous vehicle exiting process in S 63 . The autonomous vehicle exiting process is a process of moving the autonomous vehicle  18  to the vehicle exiting chamber  5 . 
     The autonomous vehicle exiting process ends when a vehicle exiting position is set in the vehicle exiting chamber  5 , the guide route from a current location of the autonomous vehicle  18  to the vehicle exiting position is set, the autonomous vehicle  18  is traveled according to the guide route, and a notification that the autonomous vehicle  18  arrived at the vehicle exiting position has been unloaded is received. 
     When the autonomous vehicle exiting process ends, in S 129 , the state restoring unit  47 D of the management device  39  restores the operation states of the target electrical components  77  and the specific electrical components  79  to the normal mode, that is, the state before the shift to the AVP mode. That is, when the operation of the target electrical component  77  is restrained, the state restoring unit  47 D restores the operation state of the target electrical component  77  to the operation state of the target electrical component  77  recorded in the memory  53  before the user gets on the autonomous vehicle  18 . However, when the user inputs the setting such as the vehicle-exiting setting, the setting made by the user is given priority. 
     When the process ends, the management device  39  ends the process. 
     14. Automatic Vehicle Unentering Process Executed by Autonomous Vehicle  18   
     An automatic vehicle exiting process executed by the autonomous vehicle  18  will be described with reference to  FIG.  7   . The automatic vehicle exiting process starts when the IGON instruction is received in the vehicle exiting setting process executed by the management device  39 . The automatic vehicle exiting process is a process of causing the autonomous vehicle  18  to travel from the parking position to the vehicle exiting chamber  5  in accordance with the vehicle exiting setting process executed by the management device  39 . 
     In the automatic vehicle exiting process, as shown in  FIG.  7   , the power of the autonomous vehicle  18 , such as the ignition, is first turned on in S 131 . Subsequently, in S 132 , the autonomous vehicle  18  determines whether there is an instruction of a vehicle-exiting setting. 
     When the autonomous vehicle  18  determines in S 132  that there is no instruction of the vehicle-exiting setting, the process proceeds to S 46 . On the other hand, when the autonomous vehicle  18  determines in S 132  that there is an instruction of the vehicle-exiting setting, the process proceeds to S 133  to reflect the setting for exiting the vehicle. When the vehicle-exiting setting is reflected, the operation states of the target electrical component  77  and the specific electrical component  79  specified by the vehicle-exiting setting are changed, and the other electrical component remains in the AVP mode. 
     Subsequently, the processes of S 46 , S 52 , and S 55  of the automatic parking process described above are performed. After S 55 , the autonomous vehicle  18  determines whether the exiting of the vehicle is completed in S 81 . When it is detected that the autonomous vehicle  18  has arrived at the vehicle exiting chamber  5 , which is the target position, the autonomous vehicle  18  determines that the exiting has been completed. 
     When the exiting is not completed, the process returns to S 55 . When the exiting has been completed, in S 82 , the autonomous vehicle  18  transmits the exiting completion notification to the management device  39 . 
     Subsequently, in S 138 , the autonomous vehicle  18  determines whether the normal mode shift instruction has been received. When the autonomous vehicle  18  determines in S 138  that the normal mode shift instruction has not been received, the process returns to S 138 . 
     On the other hand, when the autonomous vehicle  18  determines in S 138  that the normal mode shift instruction has been received, the process proceeds to S 139 , and the autonomous vehicle  18  shifts from the AVP mode to the normal mode. The autonomous vehicle  18  shifts the operation states of the target electrical component  77  and the specific electrical component  79  to the normal mode according to the instruction from the management device  39 . However, when the operation states of the target electrical component  77  and the specific electrical component  79  before changed to the AVP mode are recorded in the memory  692  of the autonomous vehicle  18 , the autonomous vehicle  18  may be restored to the operation state at any time when the process of S 139  is performed. 
     1-3. Advantageous Effects 
     According to the embodiment described in detail above, the following effects are obtained. 
     (1a) One aspect of the present disclosure is a management device  39  configured to control the operation state of at least one electrical component mounted in an autonomous vehicle  18 . The management device  39  includes a request determination unit  47 A and an operation restraining unit  47 B. 
     The request determination unit  47 A determines whether a movement request for moving the autonomous vehicle  18  in a state where the user is not in the vehicle is received. The operation restraining unit  47 B restrains the operation of the target electrical component  77  representing an electrical component that acts on five senses of the user when the autonomous vehicle  18  is instructed to move in response to a request. 
     According to such a configuration, since an operation of the target electrical component  77  is restrained when the autonomous vehicle  18  travels without picking up the user, it is possible to reduce a use of unnecessary energy when the autonomous vehicle  18  moves. 
     (1b) One aspect of the present disclosure further includes an operation state recording unit  47 C and a state restoring unit  47 D. The operation state recording unit  47 C records the operation state of the target electrical component  77  in the memory  53  when the operation restraining unit  47 B attempts to restrain the operation of the target electrical component  77 . When the operation restraining unit  47 B restrains the operation of the target electrical component  77 , the state restoring unit  47 D restores the operation state of the target electrical component  77  to the operation state of the target electrical component  77  recorded in the memory  53  before the user gets on the autonomous vehicle  18 . 
     According to such a configuration, even if the management device  39  restrains the operation of the target electrical component  77 , when the user gets on the vehicle, the management device  39  restores the operation state immediately before the restraining of the operation, such that the user can get on the vehicle without any sense of incompatibility. 
     (1c) In one aspect of the present disclosure, the operation state recording unit  47 C records whether the power of the target electrical component  77  is turned on or off as the operation state of the target electrical component  77 , and records at least one of illuminance and color of a lamp when the power of the target electrical component  77  is turned on and the target electrical component  77  includes the lamp. 
     According to such a configuration, it is possible to record whether the power of the target electrical component  77  is turned on in the memory  53 . When the power of the target electrical component  77  is turned on and the target electrical component  77  includes the lamp, the management device  39  can record at least one of the illuminance and color of the lamp in the memory  53 . Therefore, since the management device  39  records the operation state in more detail, even if the operation of the target electrical component  77  is restrained, the operation state can be more faithfully reproduced and restored. 
     (1d) In one aspect of the present disclosure, the operation state recording unit  47 C is configured to record whether the power of the target electrical component  77  turned on or off as the operation state of the target electrical component  77 , and when the power of the target electrical component  77  is turned on and the target electrical component  77  includes an air conditioner, at least one of a set temperature, an air volume, a blowing port position, and a distinction of an inside air circulation or outside air circulation of the air conditioner is recorded. 
     According to such a configuration, it is possible to record whether the power of the target electrical component  77  is turned on in the memory  53 . When the power of the target electrical component  77  is turned on and the target electrical component  77  includes the air conditioner, the management device  39  can record at least one of the set temperature, the air volume, the blowing port position, and the distinction of the inside air circulation or outside air circulation of the air conditioner. Therefore, since the management device  39  records the operation state in more detail, even if the operation of the target electrical component  77  is restrained, the operation state can be more faithfully reproduced and restored. 
     (1e) In one aspect of the present disclosure, a state setting unit  47 E is further provided. The state setting unit  47 E sets the operation state of the target electrical component  77  according to a content set by the user and input from the mobile terminal device  45  communicably connected to the management device  39 . The state restoring unit  47 D shifts the operation state of the target electrical component  77  to the operation state set by the state setting unit  47 E. 
     According to such a configuration, when the user gets on the autonomous vehicle  18 , the operation state of the target electrical component  77  can be set to the operation state set by the user. 
     (1f) In one aspect of the present disclosure, the corresponding management device  39  is mounted in the management device  39  that transmits an instruction to the autonomous vehicle  18  to perform automatic valet parking in which the autonomous vehicle  18  moves between the getting on-off area and the parking area in the parking lot. The request determination unit  47 A determines whether a request for performing the automatic valet parking in a state where the user is not in the vehicle, as a movement request is received. 
     When the automatic valet parking is performed, the operation restraining unit  47 B switches the operation state of the target electrical component  77  to a restraining mode in which the operation of the target electrical component  77  is restrained more than before the automatic valet parking is performed. The operation state recording unit  47 C records the operation state of the target electrical components  77  mounted in the autonomous vehicle  18  that performs the automatic valet parking from the getting on-off areas  3  and  5  to the parking area  7  in the parking lot. 
     According to such a configuration, when the management device  39  has a function of transmitting an instruction in automatic valet parking, the operation state of the target electrical component  77  can be controlled well in conjunction with the automatic valet parking function. 
     (1g) In one aspect of the present disclosure, the request determination unit  47 A determines whether the request for performing the automatic valet parking, in which the autonomous vehicle  18  moves between the getting on-off areas  3  and  5  and the parking area  7  in the parking lot in a state where the user is not in the vehicle, is received as the movement request. When the automatic valet parking is performed, the operation restraining unit  47 B switches the operation state of the target electrical component  77  to a restraining mode in which the operation of the target electrical component  77  is restrained more than before the automatic valet parking is performed. 
     According to such a configuration, when the automatic valet parking is performed, since the operation mode of the target electrical component  77  is switched by switching the operation mode, the operation can be restrained with a simple process even if there are multiple target electrical components  77 . 
     (1h) In one aspect of the present disclosure, an operation setting unit  47 F is further provided. The operation setting unit  47 F sets the operation state of the target electrical component  77  according to an environment in the parking lot. 
     According to such a configuration, it is possible to set the operation state of the target electrical component  77  when the automatic valet parking is performed according to the parking lot environment. 
     (1i) In one aspect of the present disclosure, when receiving a request for starting the automatic valet parking, the control unit  69  of the autonomous vehicle  18  switches the operation state of the target electrical component  77  to the AVP mode. 
     According to such a configuration, when the automatic valet parking is performed according to an instruction from an external device such as the management device  39 , it is possible to immediately shift to the AVP mode. 
     (1j) In one aspect of the present disclosure, the target electrical component  77  includes at least one of a device visually recognized by the user in the vehicle and an accessory device. 
     According to such a configuration, since there is a high possibility that the device visually recognized by the user in the vehicle and the accessory device do not need to be operated when the user is not in the vehicle, it is possible to efficiently reduce consumption energy when the autonomous vehicle  18  is operated unmanned. 
     (1k) One aspect of the present disclosure further includes an other-device control unit  47 G. The other-device control unit  47 G controls at least one of a setting of the air conditioner, a setting of inside air circulation and outside air circulation, and an operation state of the accessories, together with the target electrical component  77 . 
     According to such a configuration, it is possible to control at least one of other devices, that is, the setting of the air conditioner, the setting of inside air circulation and outside air circulation, and the operation state of an accessory, together with the target electrical component  77 . 
     2. Other Embodiments 
     Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments, and can be realized in various modifications. 
     (2a) In the embodiment, the management device  39  has the a function of controlling the operation state of the target electrical component  77 , but the present invention is not limited thereto. For example, the autonomous vehicle  18  may have this function. In this case, when the power of the vehicle is turned on in response to the instruction from the management device  39  or the like, and when the autonomous driving such as automatic valet parking is performed in a state where any person such as a user is not in the vehicle, the control unit  69  of the autonomous vehicle  18  may be configured to immediately shift to the AVP mode. 
     According to such a configuration, when the power of the autonomous vehicle  18  is turned on in response to an instruction from an external device such as the management device  39 , the operation state of the target electrical component  77  can shift to the AVP mode without receiving a separate instruction to shift to the AVP mode. 
     (2b) The control unit  69  of the autonomous vehicle  18  may set such that a predetermined specific electrical component  79  other than the target electrical component  77  operates when shifting to the AVP mode. 
     According to such a configuration, it is possible to operate the specific electrical components  79  such as the electrical components necessary for the autonomous driving function without depending on the instruction from an external device such as the management device  39 . 
     (2c) The configuration of the present disclosure is applicable to other than the autonomous vehicle  18  in automatic valet parking. For example, in an autonomous vehicle, such as an autonomous taxi and an autonomous truck, which is traveled in response to a command from an external device such as the management device  39  or the like, the autonomous vehicle may be switched between the AVP mode and the normal mode depending on the presence or absence of passengers.

Alternatively, the control unit  47   of the management device  39 , the control unit  69  of the autonomous vehicle  18 , and the methods thereof described in the present disclosure may be implemented by one or more dedicated computer, which is configured with a combination of a processor and a memory, which are programmed to perform one or more functions, and a processor which is configured with one or more hardware logic circuits. The computer programs may be stored, as instructions to be executed by a computer, in a tangible non-transitory computer-readable recording medium. In the methods for implementing functions of each unit of the control unit  47  of the management device  39  and the control unit  69  of the autonomous vehicle  18 , it does not necessarily include software, and the entire function thereof may be implemented using one or more pieces of hardware. 
     (2e) Multiple functions of one constituent element in the embodiment may be implemented by multiple constituent elements, or a function of one constituent element may be implemented by multiple constituent elements. Multiple functions of the plurality of constituent elements may be implemented by one constituent element, and one function implemented by multiple constituent elements may be implemented by one constituent element. A part of the configuration of the embodiment may be omitted. At least a part of the configuration of the embodiment may be added to or substituted for the configuration of the other embodiment. 
     (2f) In addition to the parking assistance system  1  described above, the present disclosure can be implemented in various forms, such as each device that is a constituent element of the parking assistance system  1 , a program for causing a computer to function as a device that constitutes the parking assistance system  1 , and a non-transitory tangible storage medium such as a semiconductor memory in which the program is recorded, a parking assistance method, and an electrical component control method.
