[0083] In summary, a vehicle control system is formed according to the vehicle control method, so that the specific steps of the vehicle control method are as follows:

[0084] Step 1: The controller monitors signal changes within the vehicle's control system.

[0085] Step 2: If the controller detects that the vehicle is in the ON gear, it determines whether it is currently in a wading state. If it is in a wading state, it further collects the current sensor signal information.

[0086] Step 3: When the controller detects that the vehicle is in wading state, it collects the current wading depth information. The wading depths are divided as follows: X1 corresponds to wading in the door panel cavity, X2 corresponds to water flowing over the threshold into the threshold sealing cavity, and X3 corresponds to water flowing over the threshold into the cockpit body floor. There is a certain water pressure outside the vehicle.

[0087] Step 4: The controller calculates the current required to drive the first driving member 131 according to the currently required water discharge volume.

[0088] Step 5: The controller determines whether the current required currently reaches the maximum stall current of the motor. If it is less than or equal to the maximum stall current, the controller directly drives the actuator to perform the maximum water filling or air filling action.

[0089] Step 6: The controller drives the motor to operate, and the vehicle's control system performs drainage operations according to the actuator's signal.

[0090] Step 7: The controller detects the sensor signal and issues an automatic water filling or air filling command to perform drainage operations according to different wading depths.

[0091] Step 8: The controller stops driving the current action, maintains the current motor position, and performs the braking action.

[0092] Step 9: The controller collects the current wading status and the power status of the vehicle. When the wading depth of the vehicle is less than X1 or the vehicle exits the ON gear, the vehicle exits the water and air filling mode.

[0093] Step 10: The controller drives the actuator to perform the reset action, and the water in the door sealing strip 132 is discharged. After the reset is completed, the water and air filling functions are restored and wait.
