Problems solved by technology
[0002] At present, most of the signal lights of the car are turned on directly, which cannot reflect the time, cannot attract attention, and lacks aesthetic feeling. For example: the rear position light is always on, and the light color of both is red when the brake light is on. , and generally there is not much difference between the two light intensities to the naked eye, especially in the daytime when the light is strong
If all the opening methods are like this, it can’t give people a good reminder and can’t play its role. It’s not easy for the driver following the car to confirm whether the brake light is on, and it can’t quickly arouse vigilance and easily lead to accidents.

Embodiment Construction
[0012] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0013] Embodiments of the present invention provide a control system for automobile signal lamps, such as figure 1 As shown, after the power supply is loaded, the body control module (BCM) and the lamp driver main control chip (MCU) work, which includes the body control module, the lamp driver main control chip, and the high-side driver chip (HSD). A crystal oscillator is used to provide a clock signal for the main control chip of the vehicle light drive, the vehic...

The invention provides a control system of an automobile signal lamp. The control system comprises an automobile body control module, an automobile lamp driving main control chip and a high side driving chip. The automobile body control module emits a control signal and transmits the control signal to the automobile lamp driving main control chip through an input circuit; the automobile lamp driving main control chip receives and processes the control signal and then transmits the control signal to the high side driving chip at a set time interval; and the high side driving chip controls light-emitting diodes of a brake lamp set to be lightened. According to the control system of the automobile signal lamp, the light-emitting diodes are lightened in interval and gradually-varying luminance modes, so that identifiability is higher compared with a signal lamp lightened in a traditional mode, and running safety is ensured.
Description
technical field [0001] The invention relates to the technical field of automobile lamp tube control, in particular to an automobile signal lamp control system. Background technique [0002] At present, most of the signal lights of the car are turned on directly, which cannot reflect the time, cannot attract attention, and lacks aesthetic feeling. For example: the rear position light is always on, and the light color of both is red when the brake light is on. , and generally there is little difference in the light intensity between the two to the naked eye, especially in the daytime when the light is strong. If all such opening methods can not give people a good reminder and cannot play its role, it is not easy for the driver following the car to confirm whether the brake light is on, and it is not easy to cause vigilance quickly and easily lead to accidents. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention ...
