Abstract

The invention discloses an arbitration method and system for emergency steering, belongs to the technical field of driving assistance; steering lane changing is performed to avoid front dangers if left and right adjacent lanes of a lane where a vehicle is located have no other target objects when an automatic emergency braking system cannot avoid risks. If other target objects exist on only one side of the left and right adjacent lanes, emergency steering is carried out on the adjacent lanes without the target objects; if other target objects exist in the left and right adjacent lanes, the danger degrees of the left and right adjacent lanes are determined respectively, and if the lanes with the danger degrees smaller than a preset danger degree threshold value exist and danger can be avoided after lane changing, lane changing steering is conducted on the lanes; if the lane with the danger degree smaller than the preset danger degree threshold does not exist, steering is not conducted.According to the invention, a safer emergency steering strategy can be realized.

Description

technical field [0001] The invention belongs to the technical field of driving assistance, and more specifically relates to an emergency steering arbitration method and system. Background technique [0002] Today, with the development of autonomous driving, active safety is becoming more and more important. Currently, in the field of assisted driving, only the Autonomous Emergency Brake (AEB) system can actively intervene in emergencies, but in many cases, automatic emergency braking is unavoidable. The occurrence of collisions, such as the relative speed of the two vehicles is too high, the relative distance is too small, the vehicle in front suddenly brakes suddenly, and pedestrians crossing the front suddenly appear in many scenarios. In these scenarios, if there is an emergency steering system, many dangers can be avoided ACCIDENT. According to driving experience, when a driver encounters an emergency and has no time to brake, he will choose emergency steering to avoid,...
