A switch 24, a rear right seat door switch 25, a vehicle speed sensor 26 as a vehicle speed detecting means, and an ignition key switch 15 are connected.

  The keyless lock unit 17 is interlocked with the door lock actuators (not shown) of the driver seat door 27, the passenger seat door 28, and the rear left and right seat doors 29, 30 by an output signal of a switch operation of a keyless remote control switch (not shown). Then, a rear gate lock actuator (not shown) is operated to lock and unlock the rear gate 12, which is one of unlocking and unlocking means. Therefore, the rear gate lock signal or the rear gate unlock signal output from the keyless lock unit 17 is input to the control circuit 14.

  The central door lock / unlock switch 18 is disposed in the vicinity of the driver's seat door 27, and the rear gate 12 is locked in conjunction with the doors 27 to 30 according to the switch operation of the central door lock / unlock switch 18. This is one of unlocking and unlocking operation means. Therefore, the rear gate lock signal or the rear gate unlock signal output from the central door lock / unlock switch 18 is input to the control circuit 14.

  The rear gate open switch 19 is disposed on the rear gate 12 at the rear of the vehicle body so that a switch operation as a preset detection operation is performed. When the rear gate open switch 19 is operated, a rear gate open signal for opening the rear gate 12 is input to the control circuit 14.

The driver seat door switch 22 is disposed near the driver seat door 27 and is turned on when the driver seat door 27 is opened and turned off when the driver seat door 27 is closed. When the driver's seat door 27 is opened, a driver's seat door open signal is input to the control circuit 14 from the driver's seat door switch 22.
The passenger seat door switch 23 is disposed near the passenger seat door 28 and is turned on when the passenger seat door 28 is opened and turned off when the passenger seat door 28 is closed. When the passenger seat door 28 is opened, a passenger seat door open signal is input to the control circuit 14 from the passenger seat door switch 23.

  The rear left seat door switch 24 and the rear right seat door switch 25 are disposed in the vicinity of the rear left and right seat doors 29 and 30, respectively, and are turned on and closed when the rear left and right seat doors 29 and 30 are opened. This switch is turned off. Therefore, the control circuit 14 has a rear door opening signal from the rear left seat door switch 24 when the rear left seat door 29 is opened, and a rear door opening from the rear right seat door switch 25 when the rear right seat door 30 is opened. A signal is input.

On the other hand, the rear gate open actuator 11 and the lamp 31 are connected to the output port of the control circuit 14.
The rear gate open actuator 11 is a rear gate driving device disposed around the rear gate 12. The rear gate open actuator 11 is configured to open the rear gate 12 in a closed state based on a control signal output from the control circuit 14.

  The lamp 31 is disposed in a meter panel or the like as notification means, and is configured to light up in a state in which the rear gate 12 can be opened by a control signal from the control circuit 14. Note that the notification means is not limited to the lamp 31, and a warning sound or the like can also be used.

  The control circuit 14 then sets the vehicle speed to a preset vehicle speed, for example, 3 km, based on output signals from the vehicle speed sensor 26, the driver seat door switch 22, the passenger seat door switch 23, and the rear left and right seat door switches 24, 25. When the value exceeds / h, the rear gate open switch operation performed after that (that is, after the vehicle speed exceeds the set vehicle speed) is set in advance to be invalidated. That is, it is preset that the rear gate open signal output from the rear gate open switch 19 is invalid and the control signal is not output to the rear gate open actuator 11.

  Further, in the state where the switch operation of the rear gate open switch 19 is invalidated, the control circuit 14 is in a stopped state and at least one of the seat doors 27 to 30 is in an open state once (that is, This is a state different from the closed state, and is set in advance so as to cancel the invalidation of the rear gate open switch operation when the open state includes a half-door state.

Furthermore, the control circuit 14 determines whether or not to invalidate the rear gate open switch operation based on the rear gate lock signal and the rear gate unlock signal from the keyless lock unit 17 and the central door lock / unlock switch 18. To do. When the doors 28 to 30 except for the driver's seat door 27 are opened, the rear gate 12 is preset so that the rear gate open switch operation is disabled when the rear gate 12 is in the locked state.
On the other hand, when the rear gate 12 is in the unlocked state, it is set in advance to cancel the invalidation of the rear gate open switch operation.

  Further, the control circuit 14 is preset so as to notify the occupant by turning on the lamp 31 in a state where the invalidity of the rear gate open switch operation is released. Further, when the ignition key switch 15 is turned off (engine stop), if the rear gate 12 is unlocked (the rear gate lock signal is not input), the operation of the rear gate open switch can be disabled without detecting the door opening. It is preset to reset. These settings described above are stored in advance in the ROM of the control circuit 14 as a rear gate open actuator control program.

  Next, rear gate open actuator control performed by the control unit 13 of the rear gate drive control device 10 will be described with reference to FIGS. 2 and 3 are flowcharts of the rear gate open actuator control performed by the control unit of the rear gate drive control device.

  First, when the power is turned on, initialization of the control unit 13 is started, and a rear gate open actuator control program stored in advance in the ROM of the control circuit 14 is read into the CPU. When the control program is started, in step 10, reading of output signals and detection values from the keyless lock unit 17, the various switches 18 to 25, and the vehicle speed sensor 26 is started.

  Then, in the next step 11, it is determined from the rear gate lock signal from the keyless lock unit 17 and the central door lock / unlock switch 18 whether or not the rear gate 12 is unlocked. When it is determined that the rear gate 12 is in the unlocked state, the process proceeds to step 14. On the other hand, when it is determined that the rear gate 12 is in the locked state, the routine proceeds to step 14.

  In step 12, invalidity of the rear gate open switch operation is set. Then, the process proceeds to the next step 13 where it is determined whether or not the occupant notification lamp 31 in the meter is lit. If the lamp 31 is lit, the process proceeds to step 14 and the lamp 31 is turned off, and the process returns to step 11. If the lamp 31 is not lit, the process returns to step 11 and the rear gate 12 is determined to be unlocked. Until the rear gate open switch operation is disabled.

  In step 15, it is determined whether or not the vehicle has exceeded the set speed based on the detection value from the vehicle speed sensor 26. When it is determined that the vehicle has exceeded a preset speed, the process proceeds to the next step 16 where invalidity of the rear gate open switch operation is set. On the other hand, if it is determined that the vehicle does not exceed the set speed, the process proceeds to step 24.

  In step 17, it is determined whether or not the vehicle has stopped based on the detection value from the vehicle speed sensor 26. If it is determined in step 17 that the vehicle is stopped, the process proceeds to step 20 to start the rear gate open switch invalid release determination, and the process proceeds to the next step 21. If the vehicle is not stopped, the process proceeds to step 18 to determine whether or not the occupant notification lamp 31 in the meter is lit. If it is lit, the process proceeds to step 19. The lamp 31 is turned off and the process returns to step 16, and if it is not lit, the process returns to step 16 as it is and the invalidity of the rear gate open switch operation is maintained.

  In step 21, it is determined from the rear gate lock signal from the keyless lock unit 17 and the central door lock / unlock switch 18 whether or not the rear gate 12 is in the unlocked state. When it is determined that the rear gate 12 is in the unlocked state, the routine proceeds to step 22. On the other hand, when it is determined that the rear gate 12 is in the locked state, the routine proceeds to step 12.

  In step 22, it is determined whether or not the ignition switch 15 is in an off state. Then, when it is determined that the ignition switch 15 is on, the process proceeds to step 23. On the other hand, when it is determined that the ignition switch 15 is in the OFF state, the process proceeds to step 24.

  In step 23, it is determined whether or not at least one of the doors 22 to 25 has been opened based on detection values from the driver's seat door switch 22, the passenger seat door switch 23, and the rear left and right seat door switches 24 and 25. Is done. If it is determined that the door has been opened, the process proceeds to step 24. If the door cannot be opened, the process returns to step 17.

  In step 24, it is determined whether or not the operation of the rear gate open switch is invalid. If it is determined that the operation is invalid, the process proceeds to step 25 to cancel the invalidation of the rear gate open switch operation. Further, the process proceeds to step 26, the lamp 31 in the meter is turned on to notify the occupant that the invalidation of the rear gate open switch operation has been canceled, and the process proceeds to step 27. If it is determined that it is not invalid, the process proceeds to step 27.

In step 27, it is determined whether or not a rear gate open signal from the rear gate open switch 19 has been input. Here, when the switch operation of the rear gate open switch 19 is performed, the process proceeds to step 28, and the rear gate 12 is opened.
On the other hand, if there is no rear gate open switch operation, the process returns to step 17.

  As described above, the control circuit 14 of the control unit 13 invalidates the rear gate open switch operation once the vehicle starts running and the vehicle speed exceeds the set speed. The invalidation of the rear gate open switch operation is canceled only when the vehicle is stopped and at least one of the seat doors 22 to 25 is opened once. Thus, even if the vehicle is stopped during traveling, the rear gate 12 is not opened even if the rear gate open switch is operated unless one of the doors is opened once. Accordingly, a person other than the occupant cannot open the rear gate 12 without permission, and the opening operation of the rear gate 12 when the rear gate open switch operation is performed unintentionally is prevented.

  In addition, when the occupant opens the rear gate 12 and takes out the luggage, it is necessary to open the door from the parked vehicle and get off the vehicle, so that convenience is not impaired and the user is inconvenienced. Absent. Further, since the rear gate open switch operation itself is invalidated, the rear gate open actuator 11 that locks and unlocks the rear gate 12 does not operate every time the switch operation is performed. Accordingly, no operation noise is generated, the in-vehicle comfort is improved, and the deterioration of the rear gate open actuator 11 is prevented.

  Further, if the rear gate 12 and the plurality of doors 27 to 30 are locked in advance, any one of the plurality of doors 28 to 30 except for the driver's seat door 27 is opened once by stopping the vehicle during traveling. Even if it becomes a state, the invalidity of the rear gate open switch operation is maintained. Therefore, the driver's willingness to intentionally keep the rear gate 12 in the locked state is given top priority, and the usability of the rear gate 12 is improved. Then, when the rear gate 12 and the plurality of doors 27 to 30 are collectively unlocked, the invalidity of the rear gate open switch operation is released. For this reason, since the invalidation of the rear gate open switch operation can be easily canceled, the usability of the rear gate 12 is further improved.

  Furthermore, if the door is not opened while the vehicle is stopped, the rear gate 12 will not open even if the rear gate open switch 19 is pushed by a rear impact. Thereby, the opening operation of the rear gate 12 at the time of a rear collision can be prevented. Therefore, the rear gate 12 does not open at the time of the rear collision, and the luggage or the like is not thrown out of the vehicle, and the safety measures at the time of the rear collision are not impaired. In addition, theft of luggage loaded in the rear luggage room is prevented.

  The present invention is not only applied to the rear gate (back door), but can be applied to, for example, a trunk lid, an auto slide door, and the like.
