The present invention provides a backlight adjustment system and method for automobiles. The backlight adjustment system includes: a touch switch module, a vehicle body controller, a door panel switch, a central control panel switch, a combination instrument, an audio panel, and an air-conditioning panel; The switch module includes a touch switch, a power conversion module and a processor; the touch switch module is connected with the body controller, the door panel switch, and the center control panel switch through the LIN bus; the body controller is also connected with the combination meter, The connection between the audio panel and the air conditioner panel can avoid the problems of poor anti-interference of the PWM signal output by the mechanical roller-type backlight adjustment switch and easy wear of mechanical parts.
Description
technical field [0001] The invention relates to the technical field of automobile backlights, in particular to an automobile backlight adjustment system and method. Background technique [0002] With the development of technology, people's requirements for the comfort of cars and the degree of intelligence of technology, more and more touch switches or touch screens are used in cars, bringing excellent customer experience to drivers . However, as far as the backlight adjustment system of the car is concerned, most of the backlight adjustment switches of the mechanical roller type are still used at present. By adjusting the sliding variable resistor inside the switch, the PWM signal is output, and the duty ratio of the PWM signal is adjusted to achieve adjustment. Purpose of backlight brightness. However, the mechanical roller type backlight adjustment switch has the following disadvantages: [0003] 1. The PWM signal output by the backlight adjustment switch has poor anti...
