Abstract
The utility model provides a detecting braking system of a vehicle red light, and belongs to the technical field of automotive electronics. The detecting braking system of the vehicle red light solves the problems in the prior art that installation is troublesome, and practical applicability is not high. The detecting braking system comprises a front-facing camera, an electronic control unit (ECU) processor and a braking system. The front-facing camera is connected at a signal input end of the ECU processor. The braking system is connected at a signal output end of the ECU processor. The front-facing camera shoots information of a traffic signal lamp and then outputs picture signals. The ECU processor receives the picture signals and then analyses and judges the picture signals. When the ECU processor judges that the traffic signal lamp is a green light, follow-up operation is not operated, when the ECU processor judges that the traffic signal lamp is a red light or a yellow light, a control command is outputted to the braking system, and then the braking system adopts braking operation based on the control command which is received. The system enables the phenomenon that a driver runs the red light to be prevented timely, occurrence of a road accident caused by a human factor is avoided, and transportation safety at an intersection is guaranteed.
