When the control module 10 receives this signal, it will control the action of the motor 210 provided by the drive device 20 to close the back door. In the off position, the full close switch 350 will send a signal to the control module 10, and the control module 10 will stop the action of the motor 210 after receiving the signal.

D: When the back door is being opened electrically (the position of the back door can be zone 2 or zone 3), the user can send a signal by using the close button 50, the remote control 41 or the switch button 43, and the signal control module 40 will send the remote control 41 or the signal of switch button 43 is transmitted to the control module 10, when the control module 10 receives this signal, it will control the motor 210 set in the driving device 20 to act, so that the back door is closed, and when the back door is closed to the fully closed position , the fully closed electric door 350 will send a signal to the control module 10, and when the control module 10 receives the signal, it will stop the action of the motor 210. Moreover, if the back door is in electric opening, and the back door position is In area 1, when the signal sent by the user's off button 50, remote controller 41 or switch button 43 is sent to the control module 10, the control module 10 will ignore the signal and continue the action before receiving the signal.

E: When the back door is being electrically closed (the position of the back door can be zone 2 or zone 3), the user can send a signal by using the remote control 41 or the switch button 43, and the signal control module 40 will send the remote control 41 or the switch button 43 signal to the control module 10, when the control module 10 receives this signal, it will control the motor 210 set in the driving device 20 to open the back door, and when the back door is opened to the fully open position, the full Opening the electric door 230 will send a signal to the control module 10, and when the control module 10 receives this signal, it will stop the action of the motor 210. Moreover, if the back door is in the electric closing process and the back door is in zone 1, When the signal sent by the remote controller 41 or switch button 43 used by the user is sent to the control module 10, the control module 10 ignores the signal and continues to perform the action before receiving the signal.

F: When the back door is being opened electrically and the vehicle changes to motion (motion is defined as: the speed is above 5 kilometers per hour or the gear lever is in a position other than the parking gear), the control module 10 will control the motor 210 provided by the driving device 20 Action to close the back door, and when the back door is closed to the fully closed position, the full close switch 350 will send a signal to the control module 10, and the control module 10 will stop the action of the motor 210 after receiving the signal.

G: When the back door is being electrically closed and the vehicle changes to motion (motion is defined as: the speed is above 5 kilometers per hour or the gear lever is in a position other than the parking gear), the control module 10 will ignore this vehicle motion and continue to close the back door. Door.

Moreover, the control module 10 will first drive the door lock motor 340 to open the electric door lock 310 before each time the motor 210 is to be opened, and then drive the motor 210, and the door lock motor 340 will drive a section of After a period of time, the electric door lock 310 is reset, and the control module 10 performs a closing action on the drive motor 210, and when the back door is closed to push the electric door lock 310 into a half-lock state, the half-lock sensing switch 330 will Send a signal to the control module 10, at this time the control module 10 will drive the door lock motor 340 to make it a closed drive, and let the electric door lock 310 become a full lock state, and when the electric door lock 310 becomes a full lock state , the full lock sensing switch 320 will send a signal to the control module 10, so that the control module 10 reversely drives the door lock motor 340, and when the door lock motor 340 returns to the center position, the motor center sensor The switch 360 sends a signal to the control module 10 , so that the control module 10 stops driving the door lock motor 340 .

In addition, when the control module 10 activates the motor 210, the anti-pinch sensing device 70 will detect whether there is an obstacle in the opening or closing path of the back door at any time, and when an obstacle is sensed, the control module 10 will Immediately reverse the motor 210 to prevent collision or pinching.

The buzzer 220 will sound when the anti-trap sensing device 70 detects that there is an obstacle in the opening or closing path of the back door to warn the user, and when the user uses the close button 50 to close the back door, In order to prevent unexpected and misused situations, the control system 10 will first delay for a fixed period of time and activate the buzzer 220 to remind the user, and then drive the motor 210 to operate.
