Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0040] See figure 1 , figure 1 It is a schematic diagram of the flow of pedestrians passing through the self-driving cars of the present invention. The number of lanes is two-way 4 lanes, including l1, l2, l3 and l4. The technical solution of the invention, but in specific applications, the decision-making method for the right of way of an automatic driving vehicle to be protected by the present invention is not limited to the road environment at uncontrolled intersections, but also applicable to the passage of automatic driving vehicles in road environments such as road sections, near shopping malls, and around schools. decision-making process.

[0041] The right-of-way decision-making method for an autonomous vehicle when facing pedestrians provided by the present invention comprises the following steps:

[0042] Step S1: Pedestrian Risk Assessment...

Abstract

The invention discloses a traffic right decision-making method for an automatic driving automobile in facing pedestrians, and the method comprises the steps: S1, carrying out the evaluation of the risk value of a pedestrian in a road from the environment and an automatic driving traffic flow based on an acceptable gap theory; S2, estimating a pedestrian passing intention; and S3, determining an automatic driving vehicle passing scheme according to the risk value of the pedestrian, the waiting time and the pedestrian passing intention. According to the traffic right decision method for the automatic driving automobile in facing the pedestrian, the problem that the traffic right decision of the automatic driving automobile is inflexible and unidirectional is solved, so that the operation stability and efficiency of the automatic driving traffic flow are greatly improved, the phenomenon that the current automatic driving automobile frequently stops when facing the pedestrian is reduced. The method has remarkable effects of improving the safety of pedestrians, improving the traffic efficiency of road traffic flow and the like of the automatic driving automobile.

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...
