The controller receives pressure values generated by the pressure sensors, and calculates the touch position according to the pressure values received by the different pressure sensors. The touch position is matched with the switch function area on the touch panel, if the touch position is overlapped with the switch function area, the matching is successful, and the driver is determined to press the switch function area.

referring to fig. 3, a steering wheel touch switch system includes a touch panel 1, a controller, a head-up display module, a voice broadcast module, and a pressure sensor 2.
The touch panel 1 is arranged in the middle of a steering wheel, the front side of the touch panel 1 is provided with a plurality of switch function areas 3 with the numbers of A, B, C, D and E, four pressure sensors 2 with the numbers of 1, 2, 3 and 4 are arranged between the adjacent switch function areas 3 (the pressure sensors 2 can be a plurality, in the embodiment, only four pressure sensors 2 are used as examples), the four pressure sensors 2 are distributed on the touch panel 1, the four pressure sensors 2 can form a square after being connected with each other, the four pressure sensors 2 are located at right-angle positions of the square, and the pressure sensors 2 are arranged on the back side of the touch panel 1. Every area on touch panel 1 all presets the pressure value, and the pressure value that pressure sensor 2 received matches with presetting the pressure value, if match successfully, then can be according to the position of the pressure value of presetting of the pressure value of the pressure sensor 2 that receives, promptly touch the position.
When the a switch function area 3 on the touch panel 1 is pressed by the finger of the driver, the four pressure sensors 2 with the numbers 1, 2, 3 and 4 in the touch panel 1 are respectively pressed and generate pressure values, the pressure values generated by the four pressure sensors 2 are compared with the preset pressure values of the a switch function area 3 (the preset pressure values given by the a switch function area 3 can be multiple, and each preset pressure value has one pressure sensor 2 corresponding to it), the pressure value sensed by the pressure sensor 2 with the number 1 is 10n, the pressure value sensed by the pressure sensor 2 with the number 2 is 5n, the pressure value received by the pressure sensor 2 with the number 3 is 4n, the pressure value received by the pressure sensor 2 with the number 4 is 9n, the pressed position of the driver can be known by matching the pressure values respectively received by the four pressure sensors 2 with the numbers 1, 2, 3 and 4 with the preset pressure values on the touch panel 1, and the pressed position of the pressure sensors 2 with the numbers 1, 3 and 4 is determined as the pressed position of the switch function area 3, and the pressed position of the switch function area 3 is determined as the pressed position of the preset pressure values of the four pressure sensors 2 with the numbers 1, 2, 3 and 4.
By the way of judging the pressing area, the size and/or the track, the controller compares the touching area (the touching area is the touching position) with the preset key position (the key position is the switch function area 3) and/or the track, if the pressing area, the size and/or the track are the same as the preset information, the controller determines the matching, and the way of matching the pressure value according to the pressure value of the pressure sensor 2 and the target area is compared with the way of arranging the pressure sensor 2 at each position of the touch panel 1, so that the quantity of the pressure sensors 2 is saved, the cost is reduced, the pressure sensors 2 can be selected more widely, and the limitation of the traditional capacitance sensor to materials is avoided.

If the pressure value that detects a plurality of pressure sensor and detect does not match with the last predetermined pressure value of touch panel, then press the position and not in switch functional area 3, then new line display module and voice broadcast module can not give the suggestion.
It should be further noted that after the driver determines that the touch position is correct and then applies a force to press, the driver continues to apply pressure to the pressure sensor 2, the pressure value applied to the pressure sensor 2 is compared with a trigger pressure threshold value set in the controller, when the pressure value is greater than the trigger pressure threshold value, the controller outputs a second feedback signal, and the voice broadcast module and the head-up display module connected with the controller respectively receive the second feedback signal and start to work.

Through the content, a driver can know the specific position of the touch position of the driver on the touch panel 1, if the touch position is correct, the driver can continue to forcibly trigger the functional area 3 of the switch, if the position is wrong, the driver can adjust the touch position and determine the touch position again, and the driver can confirm the touch position without lowering the head, so that the problem that the driver lowers the head to observe and traffic accidents are easily caused is avoided.
In summary, the touched position and the pressure value are output to the controller through the pressure sensor on the touch panel, the controller generates a feedback signal after receiving information of the pressure sensor, the head-up display module and the voice broadcast module respectively display and broadcast contents contained in the first feedback signal after receiving the first feedback signal (if the detected touch position is not in the switch function region, a player of the head-up display module and the voice broadcast module does not give a prompt), the driver can observe whether the finger touch position is a functional component which the driver wants to touch control through the front windshield glass, if the finger touch position is the functional component which the driver wants to trigger, the driver can continue to apply force, the controller compares the force subsequently applied to the touch panel with a trigger pressure threshold preset in the controller, and when the judgment is greater than the trigger pressure threshold, the controller generates a second feedback signal, sends the second feedback signal to the corresponding functional component on the automobile, and triggers the functional component to operate, and by the above structure, the necessity of low-head observation of the driver can be avoided or reduced, so as to reduce the risk of driver's distraction, and improve the safety of the driver.
In addition, the head-up display module can send out a prompt in the stage of generating the first feedback signal, so that the driver is prevented from being triggered unconsciously in driving, or the driver is prevented from touching the unconsciously triggered function by mistake, and the driver is prevented from touching by mistake.
