A right-of-way decision-making method for autonomous vehicles facing pedestrians

Abstract

The invention discloses a right-of-way decision-making method for an automatic driving vehicle in the face of pedestrians, comprising: step S1: based on the acceptable gap theory, evaluating the risk value of pedestrians on the road from the environment and automatic driving traffic flow; step S2 : Estimate the pedestrian's traffic intention; Step S3: Comprehensively determine the pedestrian's risk value, waiting time and pedestrian's traffic intention to determine the traffic plan of the autonomous vehicle. The decision-making method for the right of way of an automatic driving vehicle when facing pedestrians provided by the present invention solves the problem of inflexible and one-way decision-making of the right of way for an automatic driving vehicle, thereby greatly improving the stability and efficiency of the traffic flow of automatic driving and reducing the current automatic traffic flow. The phenomenon of frequent parking when driving a car facing pedestrians has a significant effect on improving the safety of pedestrians and improving the efficiency of road traffic flow for self-driving cars.

Description

technical field [0001] The invention relates to a decision-making method for automatic driving, in particular to a decision-making method for the right of passage of an automatic driving vehicle when facing pedestrians. Background technique [0002] In the traditional road environment, the right-of-way decision-making process between vehicles and pedestrians is a common interaction scene on the road. However, in an autonomous driving environment, cars lack the ability to understand the intentions of pedestrians, and cannot communicate with pedestrians flexibly like drivers. Therefore, pedestrian accidents caused by autonomous vehicles occur frequently, and the decision-making method for the right of way has gradually become a key issue restricting the development of autonomous driving technology. In addition, due to the existence of autonomous vehicle platoon control algorithms, autonomous vehicles will move in queues in the future traffic flow, and pedestrians will interac...
