Backlight brightness adjusting system and method for automobile central panel

Abstract

The invention discloses an automobile central panel backlight brightness adjusting system which comprises an illumination detection module, a trigger module and a brightness adjusting module, the brightness adjusting module is provided with a manual adjusting unit and a self-adaptive adjusting unit, and meanwhile the invention discloses an automobile central panel backlight brightness adjusting method using the system. Comprising the following steps: acquiring central panel area illumination intensity and position lamp switching signals to determine a backlight mode; the manual dimming unit is turned on by default, a dimming signal of the manual dimming unit is obtained in real time, the backlight brightness of the central panel is adjusted according to the dimming signal, and the dimming signal and the corresponding illumination intensity are sent to the self-adaptive dimming unit; if the self-adaptive dimming unit is turned on, the backlight brightness of the central panel is automatically adjusted according to the real-time illumination intensity and the historical dimming data, the dimming behavior data of a driver is recorded to serve as the data basis of self-adaptive dimming, the use habits of the driver are fully considered, meanwhile, operation can be simplified, and safety can be improved.

[0002] With the improvement of automobile intelligence and safety performance requirements, new requirements are put forward for the central panel. In order to provide the driver with a more comfortable visual experience and ensure that the driver can accurately identify the setting instructions in the central panel during driving, the The central panel is set to day mode, night mode and dark light mode, but due to the intensity of sunlight, the height of the driver, and driving habits when the car is driving, there are still differences in the brightness requirements of the backlight in different modes. In the existing technology, the brightness adjustment button is generally set on the vehicle display screen. The driver needs to manually fine-tune the brightness of the backlight according to the actual scene. Due to the continuous change of the ambient light, repeated adjustments are required. The operation is cumbersome and will affect driving safety.
