[0027] The embodiment of the present application provides a steering wheel switch assembly 10, which is a control device arranged on a steering wheel 100, and is used to operate and control the vehicle. By connecting with the vehicle electronic system, the driver can quickly perform various functions during driving. The current steering wheel switch assembly 10 includes: a button switch, a knob switch, a touch switch, etc., which can allow the driver to better control various vehicle systems during driving and improve the overall driving experience.

[0028] See also Figure 1 As shown, the steering wheel switch assembly 10 is disposed at the left side of the steering wheel 100 , so that the driver can operate the steering wheel switch assembly 10 with the left thumb while driving.

[0029] In some embodiments, the steering wheel switch assembly 10 may also be disposed at the right side or the middle position of the steering wheel 100 .

[0030] See also Figures 1 to 3 As shown, the steering wheel switch includes: a cover 1, a sensor sheet 2 and a circuit board assembly 4; a touch panel 11 is provided on the cover 1, and a plurality of buttons 3 are provided on the touch panel 11 for receiving external touch signals; the sensor sheet 2 is fixed to the cover 1 for sensing and transmitting the touch signal of the cover 1; the circuit board assembly 4 is fixed to the sensor sheet 2 and the cover 1 for receiving the touch signal of the sensor sheet 2 and transmitting the action signal to realize some operating functions of the vehicle.

[0031] The sensor sheet 2 cooperates with the touch panel 11 to more quickly sense the driver's operation, thereby improving the sensitivity and accuracy of the operation; fixing the circuit board assembly 4 with the sensor sheet 2 and the cover 1 can improve the overall anti-interference ability of the steering wheel switch assembly 10 and reduce the probability of failure. The entire steering wheel switch assembly 10 is assembled in a modular combination, which is convenient for installation on the steering wheel 100 and is also convenient for maintenance and replacement.

[0034] The steering wheel switch assembly 10 includes a capacitor module (not shown), which is signal-connected to the touch panel 11 and the circuit board assembly 4. When the touch panel 11 is touched, the capacitor module receives the touch signal and transmits the capacitance signal to the circuit board assembly 4.

[0038] In an embodiment of the present application, multiple buttons, such as the confirmation button 31 and the left button 32 and / or the lower button 33, are pressed at the same time, and when the capacitor module detects that the capacitance change of the confirmation button 31 exceeds a preset value, the first signal is still triggered to avoid operational errors caused by accidental touches when the driver operates the steering wheel switch assembly 10, thereby improving safety.

The preset capacitance change threshold is used as the trigger condition, which can effectively avoid misoperation and improve the accuracy of control.
