Therefore, these and other directional terms should not be construed as limiting terms.
The first embodiment is as follows:
as shown in fig. 1, the control method of the electric tailgate controller includes the following steps:
step S101, receiving a trigger signal;
specifically, the trigger signal comes from the integration switch, and when a user presses the integration switch, the integration switch sends out the trigger signal, and the electric tail gate controller receives the trigger signal.
Step S102, identifying the opening and closing state of the tail gate;
step S103, receiving a trigger time signal when the tail gate is in a closed state;
specifically, the trigger time signal is from the integration switch, which sends the trigger time signal to the electric tailgate controller.
Step S104, receiving an unlocking signal of the tail gate when the triggering time is greater than a first preset time t 1;
specifically, the first preset time t1 is 100ms, and the first preset time t1 is pre-stored in the electric tailgate controller. When the electric tail gate controller judges that the triggering time is less than the first preset time t1, the operation is invalid and is not executed; and when the electric tail gate controller judges that the triggering time is greater than a first preset time t1, receiving an unlocking signal of the tail gate, wherein the unlocking signal is from a vehicle Body Controller (BCM).
And S105, opening the tail gate.
According to the embodiment of the invention, after a customer presses the integration account, the electric tail gate controller receives the trigger signal, judges whether the tail gate is in a closed state, and then opens the tail gate according to the length of the trigger time and whether the tail gate is unlocked, and finally realizes the opening of the tail gate if the tail gate is unlocked.
Further, the step S104 of receiving the unlocking signal of the tail gate further includes:
step S114, identifying the unlocking or locking state of the tail gate;
step S124, when the tail gate is in a locked state, sending an unlocking request and receiving a fed-back unlocking signal;
specifically, the electric tail gate controller sends an unlocking request to the BCM, and after the BCM unlocks the tail gate, an unlocking signal is fed back to the electric tail gate controller. After receiving the unlock signal, step S105 is executed.
And S134, executing the tail gate action request when the tail gate is in the unlocking state.
Specifically, when the electric tailgate controller recognizes that the tailgate is already in the unlocked state, the electric tailgate controller does not need to send an unlocking request to the BCM any more, but directly executes a tailgate action request. The execution of the tail gate action request performs corresponding action execution on the tail gate according to the position and the motion state of the tail gate, and the execution of the tail gate action request will be described in detail later. In step S134, when the tailgate is in the unlocked state, tailgate opening is directly performed.

step S304, when the tail gate does not move, receiving a trigger time signal;
and S305, executing the tail gate action request when the triggering time is greater than the third preset time t3 and less than the fourth preset time t 4.
Specifically, the third preset time t3 is 100ms, the fourth preset time t4 is 2000ms, and the third preset time t3 and the fourth preset time t4 are pre-stored in the electric tailgate controller. And when the electric tail gate controller judges that the triggering time is less than the third preset time t3, the operation is invalid and is not executed. When the triggering time is judged to be greater than the third preset time t3, whether the triggering time is greater than the fourth preset time t4 is continuously judged, and if the triggering time is less than the fourth preset time t4, the tail gate action request is executed.

step S404, when the tail gate does not move, receiving a trigger time signal;
and S405, when the triggering time of the integration switch is greater than a fourth preset time t4, setting the height of the tail gate.
In the embodiment of the invention, when the tail gate is opened, whether the tail gate moves or not is firstly identified, if the tail gate does not move, the triggering time is judged, and if the triggering time is more than the fourth preset time t4, the height of the tail gate is set.
