The invention provides a capacitive touch type steering wheel switch backlight control system and a control method. The control system comprises a sound box control module, a vehicle body control module, a combined switch and a steering wheel switch control module, the vehicle body control module is in communication connection with the sound box control module, the combined switch and the steering wheel switch control module, and the sound box control module is used for setting switch backlight brightness and sending a corresponding brightness value signal to the vehicle body control module; the combined switch sends a position lamp turn-on or turn-off signal to the vehicle body control module according to the turn-on or turn-off state of the position lamp switch; the vehicle body control module is used for receiving the brightness value signal sent by the sound box control module, obtaining the position lamp turn-on or turn-off signal sent by the combined switch and sending a switch backlight lightening signal and the brightness value signal to the steering wheel switch control module; the steering wheel switch control module receives the switch backlight lightening and brightness value signals sent by the vehicle body control module and controls the steering wheel switch backlight to be lightened according to the corresponding brightness value.
本发明公开了一种电容触摸式方向盘开关背光控制系统及控制方法,包括音响控制模块、车身控制模块、组合开关、方向盘开关控制模块,车身控制模块分别与音响控制模块、组合开关及方向盘开关控制模块通讯连接;音响控制模块用于设定开关背光亮度,并向车身控制模块发送相应亮度值信号;组合开关根据位置灯开关的打开或关闭状态,向车身控制模块发送位置灯开启或关闭信号;车身控制模块用于接收音响控制模块发出的亮度值信号,获取组合开关发出的位置灯开启或关闭信号,并向方向盘开关控制模块发送开关背光点亮信号及亮度值信号;方向盘开关控制模块接收车身控制模块发送的开关背光点亮及亮度值信号,控制方向盘开关背光按照相应的亮度值点亮。
