Abstract

Abstract: Aiming at the problem of high collision rate and low efficiency of traditional serial behavior tree in autonomous vehicle control, a solution based on improved parallel behavior tree architecture is discussed to achieve safe behavior control. A safety behavior control strategy under dynamic road conditions is proposed, and behavior models for observation, decision-making, and movement are constructed, as well as their temporal constraint relationships; an improved parallel behavior tree control architecture is proposed, which achieves parallel execution and real-time interaction of behaviors through parallel control nodes, improving the real-time performance of decision control. The results show that compared with traditional serial behavior trees, the parallel behavior tree architecture reduces collision rates by 23%, increases average speed by 5.4%, and reduces response time by 56.6%; compared with the architecture based on MPC, the collision rate is reduced by 2%, the average speed increased by 1.6%, and the response time is reduced by 15.7%
