The invention discloses an automatic driving vehicle trajectory planning method under the influence of an intersection accident, and belongs to the field of automatic driving vehicle trajectory planning control. The problem that the traffic efficiency of the intersection is low after an accident is solved. According to the method, the intersection environment after an accident is accurately sensed and analyzed, the driving risk field is constructed through the expected trajectory field, the accident rejection field and the vehicle motion field, the influence of various factors on the vehicle is quantified, and real-time path adjustment guidance can be provided for the automatic driving vehicle by calculating transverse and longitudinal driving force and acceleration; long-time detention and traffic jam of the vehicles caused by accidents are avoided, the vehicle passing efficiency under the intersection accident scene can be effectively improved, traffic delay is reduced, meanwhile, the driving safety is enhanced, it is ensured that the vehicles safely pass through in the complex intersection environment, and the risk of secondary occurrence of the accidents is reduced. The method can be applied to automatic driving vehicle trajectory planning under the influence of intersection accidents.
