Automotive Brake Lamp Brightness Adjustment System and Control Method

Abstract

The invention discloses an automobile brake light brightness adjustment system and its control method. Controller control, the car light controller is connected with the photosensitive sensor, car ECU and reversing radar, the photosensitive sensor is installed on the car brake light, used to detect the flashing signal of the rear car high beam light; the car ECU will obtain the brake sensor data through the CAN bus It is transmitted to the car light controller, and the reversing radar is used to obtain the following distance of the car behind. The output end of the car light controller is connected with a current controller and N power switches. The effect is: the circuit structure is simple, the installation and control are convenient, and the brightness of the taillight can be adjusted adaptively according to different braking depths and different following distances, thereby reducing the damage to the eyesight of the driver behind.

Description

technical field [0001] The invention relates to automobile electronic technology, in particular to an automobile brake lamp brightness adjustment system and a control method thereof. Background technique [0002] Automobile taillights are an essential component in the vehicle electrical system. They are mainly used to indicate the running status of the vehicle to the rear vehicles or pedestrians. The existing automobile taillights usually have two states. One is when the lights are turned on at night, the taillights are used to indicate the presence of vehicles ahead. ; The other is when stepping on, through the bright brake light, it prompts the vehicle in front of the rear to slow down or stop, so as to prevent rear-end collision. [0003] The above design can indeed realize the information interaction between the front and rear vehicles, but as urban roads become more and more congested, more and more drivers realize the seriousness of vehicle light pollution.

Problems solved by technology

[0003] The above design can indeed realize the information interaction between the front and rear vehicles, but as urban roads become more and more congested, more and more drivers realize the seriousness of vehicle light pollution. The quality of the vehicle is noble, and its lighting design is also brighter. In the process of following the car at close range, it is difficult for the driver to avoid the strong taillight light of the vehicle in front. Following the car for a long time will easily cause the driver's eyesight fatigue, which will cause traffic accidents. ACCIDENT

[0004] The defect of the existing technology: Most of the light intensity of the taillights of the car adopts a continuous high-brightness mode, which does not make adaptive adjustments according to the vehicle speed and the following distance of the car behind, thus causing visual damage to the driver who is following the car at a close distance
