Abstract

Disclosed is a driver assistance method and system for avoiding violation of traffic lights. The method includes: 1, searching for and determining location of a road traffic light where a vehicle locates, and performing a step 2; 2, calculating change time gap t_g of the road traffic light where the vehicle locates, and performing a step 3; 3, comparing the time time-gap required for the vehicle to reach a warning line and the change time gap t_g, and judging whether the current vehicle is about to violate the traffic signal light or not; if yes, executing automatic emergency braking; if not, determining that the current vehicle does not violate the traffic light. The system comprises an automatic emergency bake controller, a vehicular camera, a vehicle electronic stability control system, and a wireless communication transceiving device, wherein the vehicular camera and the vehicle electronic stability control system are connected with the automatic emergency brake controller respectively through buses. The method and system has the advantages that the defects of the existing automatic emergency brake system are made up, the traffic lights can be recognized, corresponding brake judgments are made then, and violations of traffic lights, such as a bicycle running the red light or yellow light, can be avoided effectively.

Description
