  An antenna 12 for receiving a signal transmitted from the portable device 2 is connected to the door lock CU 10, and a door lock actuator 13 for electrically locking and unlocking the door lock 11 is connected to the door lock CU 10. Further, a door lock state switch 14 for determining the state of the door lock 11 (the locked state or the unlocked state of the door lock 11) is connected to the door lock CU10. Further, a door switch 15 for detecting the open / closed state of the door is connected to the door lock CU10.

  In such a configuration, when the door lock CU 10 receives the identification signal together with the door lock signal from the portable device 2, the door lock CU 10 collates the received identification signal with previously registered ID information. As a result, when it is determined that the received door lock signal is transmitted from the appropriate portable device 2, the door lock CU 10 locks the door lock 11 through the door lock actuator 13. Further, when the door lock CU 10 receives the identification signal together with the door unlock signal from the portable device 2, the door lock CU 10 collates the received identification signal with previously stored ID information. As a result, when it is determined that the received door unlock signal is transmitted from the appropriate portable device 2, the door lock CU 10 unlocks the door lock 11 through the door lock actuator 13.

  Further, the door lock CU 10 recognizes the current state of the door lock 11 based on a signal from the door lock state switch 14. At this time, the door lock CU10 is locked from the portable device 2 when the state of the door lock 11 is switched (that is, when switching from the unlocked state to the locked state, or when switching from the locked state to the unlocked state). By checking whether or not a signal or a door unlock signal has been received, the current locking or unlocking of the door lock 11 is performed through the portable device 2 or is directly applied to the door lock 11. It is determined whether the operation is performed. Further, the door lock CU 10 recognizes the current open / closed state of the door based on a signal from the door switch 15.

  The driving equipment CU20 includes, for example, a seat driving section 21 for adjusting the position of the driver seat, a handle driving section 22 for adjusting the position of the steering wheel, as a driving section for adjusting the position of various driving equipment, A door mirror driving unit 23 for adjusting the position of the door mirror and a rearview mirror driving unit 24 for adjusting the position of the rearview mirror are connected.

  The driving equipment CU20 basically determines whether or not automatic adjustment for each driving equipment can be executed based on a signal from the portable device 2 received by the door lock CU10. And driving equipment CU20 will drive-control each drive parts 21-24, and will automatically adjust each driving equipment to each adjustment position according to ID of portable machine 2, if it judges execution permission of automatic adjustment to each driving equipment. .

  More specifically, the driving equipment CU 20 permits the execution of automatic adjustment for each driving equipment when the door lock CU 10 experiences the reception of the door unlock signal after experiencing the reception of the door lock signal from the portable device 2. judge. And driving equipment CU20 performs drive control with respect to each drive parts 21-24 on condition that the door of a vehicle was opened, for example, and adjustment according to ID of portable machine 2 which transmitted a door unlock signal Automatically adjust each driving equipment to the position. However, the driving equipment CU20 clears the experience of receiving the door lock signal from the portable device 2 and cancels the automatic adjustment execution permission for the driving equipment when a predetermined preset operation input is detected from the passenger compartment. To do.

  Here, when the driving equipment CU20 determines that the door lock CU10 has changed the locking / unlocking state of the door lock 11 without receiving the door lock signal or the door unlock signal from the portable device 2, for example, It is determined that there is an operation input from the room. Further, the driving equipment CU 20 is configured so that, for example, when an operation signal for the ignition switch 31 or the accessory switch 32 is input to the engine CU 30 or when an operation signal for the select lever 41 is input to the transmission CU 40, It is determined that there is an operation input from the room.

  Thus, in this embodiment, the driving equipment CU20 realizes each function as an adjustment unit and a determination unit.

  Next, the driving equipment position control executed by the driving equipment CU20 will be described with reference to the driving equipment position control routine shown in FIG.

  This routine is repeatedly executed at every installation time. When the routine starts, the driving equipment CU20 first checks in step S101 whether the door lock CU10 has received the door lock signal from the portable device 2. .

  And if it determines with the door lock CU10 not receiving the door lock signal from the portable device 2 in step S101, the driving equipment CU20 will progress to step S103.

  On the other hand, if it is determined in step S101 that the door lock CU10 has received the door lock signal from the portable device 2, the driving equipment CU20 proceeds to step S102 and associates it with the ID of the portable device 2 that has transmitted the door lock signal. The current adjustment position of each driving equipment is stored, and a door lock signal reception flag Fr indicating that the door lock signal has been received from the portable device 2 is set to “1”, and then the process proceeds to step S103.

  That is, it is common for the user who has finished driving to lock the door lock 11 through the portable device 2 from the outside of the vehicle. In such a case, each driving equipment is optimized by the user who operates the portable device 2. It is thought that the position has been adjusted. Therefore, the driving equipment CU20 associates the adjustment position of each driving equipment when the door lock signal is received from the portable device 2 with the ID of the portable device 2 as the optimum adjustment position of the user who owns the portable device 2. Remember.

  When the process proceeds from step S101 or step S102 to step S103, the driving equipment CU20 checks whether or not the door lock signal reception flag Fr is currently set to “1”.

  If it is determined in step S103 that the door lock signal reception flag Fr is not set to “1” (that is, if it is determined that the door lock signal reception flag Fr is “0”), the driving equipment CU20 The process proceeds to S106.

  On the other hand, if it is determined in step S103 that the door lock signal reception flag Fr is set to “1”, the driving equipment CU20 proceeds to step S104, and the door lock CU10 receives the door unlock signal from the portable device 2. Find out if you did.

  And if it determines with the door lock CU10 not receiving the door unlock signal from the portable device 2 in step S104, the driving equipment CU20 will progress to step S106.

  On the other hand, if it is determined in step S104 that the door lock CU10 has received the door unlock signal from the portable device 2, the driving equipment CU20 proceeds to step S105 and determines the ID of the portable device 2 that has transmitted the door unlock signal. After storing, the permission flag Fp permitting automatic adjustment of each driving equipment is set to “1”, and then the process proceeds to step S106.

  That is, as described above, the lock of the door lock 11 through the portable device 2 is generally performed by the user who gets off, and when receiving the door unlock signal after experiencing the reception of the door lock signal, Currently, it is estimated that a user who has unlocked the door lock 11 through the portable device 2 is about to get into the driver's seat from outside the vehicle. In other words, if the door unlock signal is received after experiencing the reception of the door lock signal, the possibility that the user is seated in the driver's seat is considered low. Therefore, the driving equipment CU20 determines whether to permit automatic adjustment for each driving equipment, and carries the mobile equipment to automatically adjust the driving equipment to a position suitable for the user who is going to get on (the user who owns the portable device 2). The ID of the machine 2 is stored. When a plurality of portable devices 2 are registered in the door lock CU 10 as in the present embodiment, the ID of the portable device 2 recognized by the door lock CU 10 when the door lock signal is received, and the door unlock signal Of course, there is no particular problem even if the ID of the portable device 2 recognized by the door lock CU 10 at the time of reception is different.

  When the process proceeds from step S103, step S104, or step S105 to step S106, the driving equipment CU20 checks whether or not a predetermined operation input is detected in the passenger compartment. That is, the driving equipment CU20 verifies whether or not the user is seated in the driver's seat by determining whether or not a preset operation input is detected in the passenger compartment.

  If it is determined in step S106 that a predetermined operation input in the passenger compartment has not been detected, the driving equipment CU20 proceeds to step S108.

  On the other hand, if it is determined in step S106 that a predetermined operation input has been detected in the passenger compartment, the driving equipment CU20 proceeds to step S107, and if the door lock signal reception flag Fr is set to “1”, the flag Fr is cleared to “0”, and when the permission flag Fp is set to “1”, the flag Fp is cleared to “0”, and the process proceeds to step S107. That is, when an operation in the vehicle interior that is set in advance is detected in step S106, it is highly possible that the user is seated in the driver's seat, so the driving equipment CU20 sets each flag Fr, Fp to “0”. clear.

  When the process proceeds from step S106 or step S107 to step S108, the driving equipment CU20 checks whether or not an opening operation has been performed on the vehicle door (for example, the door on the driver's seat side).

  If it is determined in step S108 that the door opening operation has not been performed, the driving equipment CU20 directly exits the routine.

  On the other hand, if it is determined in step S108 that the door opening operation has been performed, the driving equipment CU20 proceeds to step S109 and checks whether or not the permission flag Fp is currently set to “1”.

  If it is determined in step S109 that the permission flag Fp is not set to “1” (that is, if the permission flag Fp is determined to be “0”), the driving equipment CU20 proceeds to step S111.

  On the other hand, if it is determined in step S109 that the permission flag Fp is set to “1”, the driving equipment CU20 proceeds to step S110 and performs driving control on each of the driving units 21 to 24 to thereby install each driving equipment. After moving to the adjustment position corresponding to the ID stored in step S105, the process proceeds to step S111.

  When the process proceeds from step S109 or step S110 to step S111, the driving equipment CU20 exits the routine after resetting the door lock signal reception flag Fr and the permission flag Fp to “0”.

  According to such an embodiment, when the reception of the door unlock signal is experienced after the reception of the door lock signal from the portable device 2, the portable device is allowed to execute automatic adjustment for each driving equipment. It is possible to prevent unnecessary automatic adjustment of driving equipment from being executed when 2 is erroneously operated in the vehicle.

  That is, when the portable device 2 is erroneously operated in the vehicle, there is a high possibility that only one of the door lock switch 5 and the door unlock switch 6 is operated, and the door unlock switch 5 is operated after the door lock switch 5 is operated. The possibility that a series of operations in which the lock switch 6 is operated is extremely low. On the other hand, the user before getting on the driver's seat generally unlocks the door lock 11 through the portable device 2. Before that, the door lock 11 through the portable device 2 is usually taken by the user who gets off the vehicle. Is locked. Therefore, paying attention to these events, when experiencing the reception of the door unlock signal after experiencing the reception of the door lock signal from the portable device 2, by allowing the execution of automatic adjustment for each driving equipment, the driving equipment It is possible to accurately prevent unnecessary automatic adjustment.

  In this case, the automatic adjustment of the driving equipment is executed on the condition that the door of the vehicle is opened, so that the automatic adjustment of the driving equipment is erroneously permitted if the portable device 2 is erroneously operated in the vehicle. Even in the case of failure, it is possible to accurately prevent the automatic adjustment from being performed during traveling.

  In addition, when a preset operation input from the passenger compartment is detected, the automatic adjustment to the driving equipment is automatically canceled by canceling the permission to execute the automatic adjustment on the driving equipment, so that the portable device 2 is erroneously operated in the vehicle. Even when the adjustment execution permission is mistakenly performed, the permission can be canceled accurately.
