The present invention relates to a portable transmitter 100 for transmitting a door lock signal and a door unlock signal, and this transmission. Receiving means 101 for receiving a signal radio wave transmitted from machine 100, locking means 102 for locking or unlocking a door, mirror driving means 103 for storing or returning a door mirror, and receiving means 101 for receiving a door lock signal. Sometimes, the locking means 102 locks the door and the mirror driving means 103 stores the door mirror, and when the receiving means 101 receives the door unlock signal, the locking means 102 unlocks the door and the mirror driving means 103 causes the door mirror. Vehicle keyless entry device including control means 104 for restoring It is applied. Further, the storage means 105 for storing that the storage of the door mirror is performed in association with the door lock operation is provided, and the control means 104 stores the door mirror in the storage means 105 in association with the door lock operation. Is stored, the door mirror is restored in synchronization with the door unlocking operation, and if it is not stored in the storage unit 105 that the storage of the door mirror is performed in conjunction with the door locking operation, the door unlocking is performed. The above-mentioned object is achieved by preventing the door mirror from returning in synchronism with the locking operation.

[0006]

When the door mirror is stored in conjunction with the door lock operation, the door mirror was in the use position until the time when the passenger got off the vehicle and locked the door with the keyless entry device. It is considered not to interfere with obstacles such as. Therefore, in this case, even if the door mirror is returned to the use position in conjunction with the door unlocking operation by the keyless entry device, it should not collide with an obstacle such as a wall. On the other hand, if the storage of the door mirror is not performed in conjunction with the door lock operation, when the occupant moves the vehicle to the parking position, it is determined that the door mirror interferes with an obstacle such as a wall and the storage switch is operated. The door mirror may be stored manually or the passenger may directly rotate the door mirror body through the window to store it. Therefore, in such a case, when the door mirror is automatically returned to the use position in conjunction with the door unlocking operation by the keyless entry device, the door mirror may collide with an obstacle such as a wall. In the keyless entry device of the present invention, when the door is unlocked, the door mirror is automatically returned to the use position in the former case, and the door mirror is not automatically returned in the latter case. This prevents the door mirror from hitting a wall when the door is unlocked.

When the door lock switch 2 is continuously operated for a predetermined time T1 or more, as shown in FIG. 7B, after the door lock signal frame SF1 is transmitted, the door mirror storage signal frame SF2 is transmitted in step S5.
To send.

When the door lock switch 2 is not operated in step S1, it is determined in step S6 whether the door unlock switch 3 is closed, and if the door unlock switch 3 is closed, step S7. Otherwise, to step S8. When the door unlock switch 3 is operated, as shown in FIG. 8, a door unlock signal frame SF3 is generated and transmitted in step S7.

In step S8, it is determined whether or not the trunk lid opener switch 4 is closed. If the trunk lid opener switch 4 is closed, the process proceeds to step S9, and if not, the process proceeds to step S10.
When the trunk lid opener switch 4 is operated, a trunk lid open signal frame is generated and transmitted in step S9. Since the door opening process of the trunk lid is not directly related to the present invention, the illustration of the time chart and the detailed operation description are omitted.

When the operated switch is neither the door lock switch 2, the door unlock switch 3 nor the trunk lid opener switch 4, it is judged that the room lamp switch 5 has been operated, and the room lamp lighting signal frame is determined in step S10. Generate and send. Since the lighting process of the room lamp is not directly related to the present invention, the illustration of the time chart and the detailed operation description are omitted.

FIG. 9 shows a control program executed by the microcomputer of the drive control circuit 12 of the controller 10. The operation of the controller 10 will be described with reference to this figure. The microcomputer of the drive control circuit 12 starts the execution of this control program when receiving the radio wave transmitted from the remote controller 1. The user personal identification number ID included in the signal frame received in step S15 is collated with the number registered in the memory 12m in advance, and in the following step S16, it is determined whether or not they match.
If they match, it is determined that the user is a legitimate user and the following process is performed. If they do not match, the process ends. When it is determined that the user is a legitimate user, it is determined whether or not the function code included in the signal frame received in step S17 is door lock. If it is a door lock, the process proceeds to step S18, and if not, step S23. Go to.

When the door lock signal frame SF1 is received, it is confirmed in step S18 that the ignition key has not been forgotten by the key insertion switch 25, and if the ignition key is still inserted, the processing is terminated to prevent the key from being contained. To do. If the ignition key has not been forgotten, the process proceeds to step S19, where a lock current is passed to the door lock actuators 13 to 16 to lock all the doors, as shown in FIG.

Next, in step S20, it is determined whether or not the door mirror storage signal frame SF2 is received. If it is received, the process proceeds to step S21, and if not, the process ends. When the door mirror storage signal frame SF2 is received after the door lock signal frame SF1 is received, as shown in FIG.
As shown in (b), in step S21, the driver side and passenger side door mirror storage / return actuators 17,
A mirror storage current is passed through 18 to store the driver-side and passenger-side door mirrors. In step S22, the flag F is set to 1 and stored in the memory 12m.

The flag F is for storing that the door mirror is stored by the keyless entry device instead of being manually operated. That is, when the keyless entry device stores the door mirror, the door mirror is automatically returned to the use position in conjunction with the door unlocking operation by the keyless entry device. When the door mirror is not stored by the keyless entry device, that is, when the storage switch 27 is operated to store the door mirror manually, or when the occupant stores the door mirror body by directly rotating the door mirror body through the window, the keyless entry device. When the door is unlocked by, the door mirror is not returned to the use position, and the operation of the door mirror return switch 28 is waited for.

When the received signal frame is not the door lock, the process proceeds to step S23 and it is determined whether the door is unlocked. If the door is unlocked, the process proceeds to step S24, and if not, the process proceeds to step S29. When the door unlock signal frame SF3 is received, step S2
In step 4, it is determined whether the flag F stored in the memory 12m is set to 1, that is, whether the keyless entry device stores the door mirror. If the keyless entry device stores the door mirror, the process proceeds to step S25. If not, the process proceeds to step S28.

When the storage of the door mirror is performed by the keyless entry device, as shown in FIG. 8, after the unlock current is supplied to the door lock actuators 13 to 16 to unlock all the doors in step S25, the process continues. In step S26, a mirror return current is passed to the door mirror storage / return actuators 17 and 18 to return the door mirror to the use position. In step S27, the flag F of the memory 12m is reset (0), and the process ends.

On the other hand, the storage of the door mirror is the storage switch 2
If it is manually performed in step 7, the unlock current is passed to the door lock actuators 13 to 16 to unlock all the doors in step S28, and the process is terminated without returning the door mirrors. In this case, flag F
Remains set (1), the flag F is reset (0) when the occupant manually operates the return switch 28 to return the door mirror to the use position after boarding.

When the received signal frame is neither the door lock nor the door unlock, it is determined in step S29 whether or not it is the trunk lid opening signal frame. If the trunk lid is opening, the process proceeds to step S30, and otherwise. It proceeds to step S31. In step S30, the trunk lid opener actuator 19 is energized to open the trunk lid.

When the received signal frame is neither the door lock, the door unlock, nor the opening of the trunk lid, it is determined in step S31 whether or not it is the room lamp lighting signal frame, and if it is the room lamp lighting, step S32. If not, the process ends. In step S32, the room lamp 20 is turned on, for example, for 30 seconds, and the process ends.

In this way, when the door mirror is stored by the keyless entry device, the door mirror is automatically restored when the door is unlocked by the keyless entry device, and the door mirror is manually stored without using the keyless entry device. If it is done, the door mirror is not restored when the door is unlocked by the keyless entry device, so the door mirror is automatically restored when the door is unlocked by the keyless entry device even if you are parked in a narrow space. First, the door mirror can be prevented from hitting a wall or the like.

In the above embodiment, the door mirror storage signal is generated and transmitted by pressing the door lock switch for a predetermined time or longer, and the controller receiving the signal stores the door mirror.
Instead of setting a dedicated door mirror storage signal for storing the door mirror, the door mirror may be stored in synchronization with the door lock operation when the door lock signal is received. In this case, if you retract the door mirror manually by operating the retract switch before locking the door, the retract processing of the door mirror will be performed again when the door is locked, but it will rotate in conjunction with the retract / restore actuator and open at the retracted end. If the limit switch is connected in series with the actuator, the stored current from the controller can be shut off, so that no binding current flows through the actuator.

Further, in the above embodiment, it is stored that the door mirror is stored in conjunction with the door lock operation by the keyless entry device, but it is stored that the door mirror is manually stored by the storage switch. You may do it.

In the structure of the above embodiment, the remote controller 1 controls the transmitter, the receiving antenna 11 and the drive control circuit 12 control the receiving means, and the drive control circuit 12 and the door lock actuators 13 to 16 control the drive means. The circuit 12 and the door mirror storing / restoring actuators 17 and 18 constitute mirror driving means, the drive control circuit 12 constitutes control means, and the memory 12m constitutes storage means.

[0032]

As described above, according to the present invention, when it is stored that the storage of the door mirror is performed in conjunction with the door lock operation by the keyless entry device, it is associated with the door unlock operation. To restore the door mirror, and if it is not remembered that the storage of the door mirror was performed in conjunction with the door lock operation by the keyless entry device, we did not restore the door mirror in conjunction with the door unlock operation. Even if the vehicle is parked in a narrow place, the door mirror is not automatically restored when the door is unlocked by the keyless entry device, and the door mirror can be prevented from hitting an obstacle such as a wall.
