Specifically, when the step S100 detects a touch operation in the first area and the step S200 detects that the display screen is in the bright screen state, the step S300 includes:
and acquiring a first function icon and a first pressing force corresponding to the touch operation in the first area, and triggering a first function corresponding to the first function icon if the first pressing force is larger than a preset pressing force threshold value.
When the touch control method is applied to adjustment of the vehicle seat, for example, a stop icon is acquired, the first pressing force of the touch operation is larger than a preset pressing force threshold value, the system judges that the touch operation is effective, the vehicle seat adjustment function is triggered to be closed, and the current adjustment process is stopped as long as the pressing force of clicking the stop icon is larger than the preset pressing force threshold value in the process of adjusting the seat.
When the method is applied to vehicle-mounted music adjustment, for example, the current vehicle-mounted music stops playing, an icon with functions of stopping playing and starting playing is obtained, the first pressing force of touch operation is larger than a preset pressing force threshold value, and the system judges that the triggering operation is effective operation and triggers the function of starting playing.
When the step S100 detects a touch operation in the second area and the step S200 detects that the display screen is in the bright screen state, the step S300 includes:
and acquiring a second function icon and a second pressing force corresponding to the touch operation in the second area, and triggering a second function corresponding to the second function icon if the second pressing force is larger than a preset pressing force threshold value.
When applied to vehicle seat adjustment, for example, a downward icon is acquired, and the second pressing force of the touch operation is greater than a preset pressing force threshold, the system determines that the trigger operation is an active operation, triggering the vehicle seat to move downward a preset distance level.
When the touch control method is applied to vehicle-mounted music adjustment, for example, the last icon is acquired, the second pressing force of the touch operation is larger than the preset pressing force threshold value, the system judges the triggering operation as an effective operation, and the function of switching to the last music is triggered.

and acquiring a third pressing force corresponding to the touch operation in the second area, and triggering a third function if the third pressing force is larger than a preset pressing force threshold.
The third function is a wake-up function when the third function is applied to adjustment of the vehicle seat, when the display screen is in a dormant state, a user clicks any position of the display screen, and if the clicked pressing force is larger than a preset pressing force threshold value, the screen is waken up, so that the screen is in a bright screen state.
The wake-up operation of the display screen can be completed through the display screen without adding physical keys, and the wake-up area is not limited to one type of area controlled by fingerprints, but is the whole second area, so that the wake-up function is more efficient.
The third function is to turn on the voice assistant and wake-up function when the third function is applied to vehicle-mounted music adjustment, when the display screen is in a dormant state, a user clicks any position of the display screen, and if the clicked pressing force is larger than a preset pressing force threshold value, the voice assistant is turned on and the screen is waken up, so that the screen is in a bright screen state.
When the display screen is acquired to be in the fault state, step S400 is executed.
S400: and acquiring a pressing force corresponding to the touch operation in the first area, and triggering a first function according to the touch operation and the pressing force acquired in the current step.
As can be seen from step S400, even if the display screen fails, the first function can be triggered to prevent injury to the passenger user or influence on the use of the related application.
The step S400 includes:
and acquiring a fourth pressing force corresponding to the touch operation in the first area, and triggering a first function if the fourth pressing force is larger than a preset pressing force threshold.
When the method is applied to vehicle seat adjustment, the first function is to close the vehicle seat adjustment function, for example, the user clicks any position of the first area, and when the fourth pressing force of the clicking action is greater than the preset pressing force threshold value, the closing of the vehicle seat adjustment function is triggered.
When the method is applied to vehicle-mounted music adjustment, if the current vehicle-mounted music is being played, the first function is a play stopping function, for example, a user clicks any position of the first area, and when the fourth pressing force of the clicking action is greater than a preset pressing force threshold value, the play stopping function is triggered.
The step S400 further includes:
