     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0026]     The invention will be described with reference to the appended drawings.  
         [0027]     A vehicle accessory adjusting system according to the first embodiment of the invention will be described with reference to  FIGS. 1-8 .  
         [0028]     As shown in  FIG. 1 , the vehicle accessory adjusting system according to the first embodiment of the invention includes an IC card  1 , a card slot unit  2 , a reader-writer  3 , a data processor  4 , a data input unit  5 , a setting data memory  6 , and various on-vehicle devices  7  such as movable seats and mirrors.  
         [0029]     The IC card  1  is constituted of a resinous card member and a one-chip microcomputer with a nonvolatile rewritable memory la such as an EEPROM or a flash memory that is embedded into the resinous card member. The IC card  1  stores personal data of a card user&#39;s using a plurality of on-vehicle accessories of a vehicle. The card slot unit  2  is fixed at a portion of a instrument panel of a vehicle to directly or indirectly communicate with the IC card  1 . The reader-writer  3  is controlled by the data processor  4  to read data from or write or rewrite data into the memory la of the IC card  1 . The data processor  4  includes a microcomputer to function as the central processing unit of the vehicle accessory adjusting system. The data input unit  5  includes various sensors and an ignition switch to provide operation data. The setting data memory  6  stores setting data for setting on-vehicle accessories of various types of vehicles such as seats and mirrors at their standard positions. The data processor  4  reads or writes the IC card  1  based on the operation data sent from the data input unit  5  and the setting data sent from the setting data memory  6 .  
         [0030]     The vehicle accessory adjusting system according to the invention can be mounted in any of a plurality of types of vehicles. The setting data of various types of vehicles are obtained from tests or experiments and stored into the setting data memory  6  beforehand. The personal data are obtained when a user adjusts some of the accessories to suit his feelings.  
         [0031]     The setting data memory  6  has a data table in which standard data on various accessories of a plurality of types of vehicles or basic data and deviation or offset data of the vehicle accessories are stored. Such data are selected from a large amount of crude data obtained from result of tests or experiments on various types of vehicles and persons. The mean values or central values of the crude data may be used for the standard data.  
         [0032]     On the other hand, the memory  1   a  of the IC card  1  stores personal data on adjusting various accessories to a user and standard data thereof. The standard data may be replaced with combinations of basic values and offset values relative to the basic values. The stored personal data may be data on respective accessories of a vehicle that the user has first set.  
         [0033]     Incidentally, it has been found that the offset values to the standard values do not change much among different types of vehicles.  
         [0034]     As shown in  FIGS. 2 and 3 , seat setting data include a seat position (of moving direction) X, seat height Y, and a seat-back angle Z. Standard offset values for respective seat positions (AX, BX, CX, etc.) of various types of vehicles such as A (sedan), B (wagon), C (sport), etc. from basic values of the seat data are respectively stored, as indicated in parenthesis in a table. Mirror data include a room mirror angle U, a right side-mirror angle V, and a left side-mirror angle W. Standard offset values for respective mirror positions (AU, BU, CU, etc.) of various types of vehicles A (sedan), B (wagon), C (sport), etc. from basic values of the mirror data are respectively stored, as indicated in parenthesis in a table.  
         [0035]     The on-vehicle devices  7  are devices for adjusting positions, angles or the like of accessories such as the seats, and the mirrors, a steering wheel. The on-vehicle device  7  may also adjust room temperature, air conditions, ventilation, deodorization, illuminations, cruise control conditions, safety devices, guiding monitors, information service system such as a navigation display system, a meter system or radio broadcasting information system, an audio-video entertainment devices, a hands-free telephone system, an emergency communication system (MAYDAY), etc. Each on-vehicle device  7  includes a control unit  71 , a handle (button or dial)  72  and a drive unit  73 .  
         [0036]     The operation of the vehicle accessory adjusting system will be described with reference to  FIGS. 4 and 5 .  
         [0037]     At first, whether the IC card  1  is inserted into the slot member  2  or not is examined at step S 101 . If the result is YES, whether an ID code of the IC card  1  and an authenticated ID code store in the accessory adjusting system tally with each other or not is examined at S 102 . Instead of the authenticated code stored in the accessory adjusting system, a user can directly input the ID code to the data input unit  5 . Subsequently, the personal data are read from the IC card&#39;s memory  1   a  at S 103  to examine whether personal data for setting one or some accessories such as a seat or mirrors are stored in the IC card&#39;s memory or not at S 104 .  
         [0038]     If the result of S 104  is YES, one or some of the on-vehicle devices  7  is or are controlled to set or adjust the one or some accessories at S 105 . If, on the other hand, the result is NO, all the accessories are set by the on-vehicle devices  7  according to the standard data at S 106 .  
         [0039]     Thereafter, whether or not a user manipulates one or some of the handles  72  to adjust one or some of the accessories or changes setting data although they have been set according to the personal data or the standard data is examined at S 107  to go to S 108  if the result is YES, where whether time to rewrite setting data or not is examined to rewrite the setting data stored in the IC card&#39;s memory la at S 109  if the result of S 108  is YES. Incidentally, the rewriting of the personal data into the IC card&#39;s memory  1   a  is usually carried out just after an ignition key switch is turned off or when a user instructs the rewriting. For example, an instruction switch is provided so that the rewriting can be carried out whenever the user turns on the switch. The rewriting can be carried out via an operation panel of another system such as a navigation system. This information is inputted to the data processor  4  by the data input unit  5 .  
         [0040]     When the user manipulates the handle  72  of the seat adjusting on-vehicle devices  7  to set seat position X of a vehicle of type A to AX 1  (+20) at S 201 , as exemplified by a flow diagram shown in  FIG. 5 , a standard offset value AX (+10) is read from a data table of the memory  6  at S  202 . At the next step S  203 , a specific offset value AX 2  (+30) is calculated based on the data at the precedent steps: AX 2 =AX 1 +AX=30  
         [0000]     Thereafter, the specific offset value AX 2  is rewritten as a personal data value Xi to be stored in the IC card&#39;s memory  1   a  at S 204 , as shown in  FIG. 7 .  
         [0041]     When the same user drives a vehicle of type B and insert the IC card  1  into the slot member  2 , the same steps as described with reference to  FIG. 4  are carried out.  
         [0042]     Thereafter, the step goes to S 401  shown in  FIG. 6 , where the personal data value Xi (30) is read from the seat position data table K 1  of the IC card&#39;s memory  1   a.  Subsequently, a standard offset value BX (20) is read from a seat position data table of the setting data memory  6  at S 402 . At the next step S 403 , a specific offset value BX 2  (30) is calculated based on the data at the precedent steps: BX 2 =Xi−BX=+10  
         [0043]     Subsequently, the seat position X is set to BX 2  (10) at S 404 .  
         [0044]     The above setting is carried out on the assumption that the specific offset values do not widely change even if the type of vehicle changes. Therefore, it is not necessary to store all the data for a plurality of types of vehicles in the IC card&#39;s memory.  
         [0045]     A vehicle accessory adjusting system according to the second embodiment of the invention will be described with reference to  FIG. 8 . Incidentally, the same reference numeral will indicate the same or substantially the same part, portion of component as the first embodiment hereafter.  
         [0046]     As shown in  FIG. 8 , the vehicle accessory adjusting system according to the second embodiment of the invention includes a memory  1 B of a portable communication tool  1 C such as mobile phone, an on-vehicle communication tool  2 A, a reader-writer  3 A, a data processor  4 , a data input unit  5 , a setting data memory  6 , and on-vehicle devices  7 . The memory  1 B is not required to be separated from the portable communication tool  2 A. The memory  1 B may be a flash memory of a built-in connector type, a stick type or the like.  
         [0047]     The communication between the portable communication tool  1 C and the on-vehicle communication tool  2 A can be achieved by means of radio waves (e.g. Bluetooth), lights, ultrasonic waves.  
         [0048]     A vehicle accessory adjusting system according to the third embodiment of the invention will be described with reference to  FIGS. 9-11 .  
         [0049]     As shown in  FIG. 9 , the vehicle accessory adjusting system according to the third embodiment of the invention includes the following drive condition sensors: a weather sensor  8   a,  a day-time-night-time sensor and a vehicle speed sensor  8   c,  in addition to the IC card  1 , the card slot unit  2 , the reader-writer  3 , the data processor  4 , the data input unit  5 , the setting data memory  6 , and the on-vehicle devices  7 . As shown in  FIG. 10 , the memory  1   a  of the IC card  1  stores personal data on various drive condition modes of adjusting various accessories. For example, the memory  1   a  has a seat position data table in which personal data values (Xi 1 -Xi 4 , Yi 1 -Yi 4 , Zi 1 -Zi 4 ) of the seat position X, the seat height Y and the seat angle Z are stored for each of a plurality of drive condition modes, such as a standard mode  1 , a rain mode  2 , a night mode  3  and a high speed mode  4 . The plurality of drive condition modes may include a rainy night mode or other combined modes. If two or more drive condition modes are applicable at the same time, a drive condition mode of a higher priority may be selected.  
         [0050]     When the use drives a vehicle of type A, the IC card  1  is first inserted into the slot member  2 . Then, substantially the same steps as described with reference to  FIG. 4  are carried out until S 107 .  
         [0051]     At the next step S 509 , data provided by the sensors  8   a,    8   b,    8   c  are inputted to go to the next step S 108 , where whether time to rewrite setting data or not is examined to rewrite the personal data for a selected mode of the IC card&#39;s memory  1   a  at S 510  if the result of S 108  is YES.  
         [0052]     A vehicle accessory adjusting system according to the fourth embodiment of the invention will be described with reference to  FIGS. 9, 11  and  12 .  
         [0053]     As indicated by a block of a broken line in  FIG. 9 , the vehicle accessory adjusting system according to the fourth embodiment of the invention further includes a history memorizing unit  9  that has a learning function.  
         [0054]     The operation of this embodiment includes the substantially same steps as the third embodiment except the step S 510 , which includes steps S 601 , S 602  and S 603 , as shown in  FIG. 12 .  
         [0055]     The history memorizing unit  9  memorizes a set of drive condition mode data that are provided based on the signal data detected by the sensors  8   a,    8   b,    8   c  and corresponding setting data (or specific offset value) of the memory  6  in a chronological order at step S 601 . That is, a predetermined number of the data or the data that are obtained for a predetermined period of time are memorized.  
         [0056]     Subsequently, a set of the most frequently applied setting data that correspond to a selected drive condition mode are selected from the memorized setting data at S 602  to rewrite the IC card&#39;s memory  1   a  with the selected setting data corresponding to the selected mode at S 603 .  
         [0057]     In the foregoing description of the present invention, the invention has been disclosed with reference to specific embodiments thereof.
