Embodiment

[0046] like figure 1 As shown, the present invention is based on the collision risk-based automatic driving vehicle and non-motor vehicle right-of-way allocation method. Its implementation includes the following steps:

[0047]Step 1. The on-board equipment on the self-driving vehicle dynamically obtains the driving information of surrounding non-motor vehicles and its own vehicle in real time, including driving speed, driving direction, location, relative distance between vehicles, and distance between vehicles and a certain point on the road. Relative distance, by returning these data to the vehicle-mounted system, the vehicle-mounted system can predict the trajectory of the vehicle and judge whether there is a conflict point in the trajectory. like figure 2 As shown in the traffic conflict scene, non-motor vehicles and autonomous vehicles corresponding to the same conflict point are the two parties to the conflict. If there is no conflict point, there is no need to use ...

Abstract

The invention discloses a collision risk-based method for assigning the right of way between an automatic driving vehicle and a non-motor vehicle. The method first judges whether there is a conflict point between the self-driving vehicle and the non-motor vehicle, and if there is a conflict point, calculates the collision risk; The self-driving vehicles and non-motorized vehicles whose collision risk is higher than the threshold calculate the street crossing urgency coefficient, and give priority to the right of way for the vehicle with the higher street crossing urgency coefficient. The invention takes safety as the primary principle, and scientifically allocates the right of way of vehicles through the information interaction between the automatic driving vehicle and the non-motor vehicle and the vehicle-road coordination technology at the intersection of the non-signal-controlled road intersection where the self-driving vehicle and the non-motor vehicle are mixed. Change the situation that self-driving vehicles always give way to non-motor vehicles, so as to reduce the waiting time of vehicles, increase the traffic speed at intersections, and make self-driving vehicles and non-motor vehicles coexist harmoniously.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a method for allocating right of way between automatic driving vehicles and non-motor vehicles. Background technique [0002] With the development of autonomous driving technology, human road users will share the road use rights with autonomous vehicles, and non-motorized vehicles will play an indispensable role among human road users. At intersections without signal control, the question of which side will pass first and which side will give way needs to be resolved through scientific and reasonable analysis. [0003] From the perspective of safety, the design procedure of autonomous vehicles is based on the principle of safety first. When an autonomous vehicle encounters a non-motorized vehicle at an intersection, it defaults to automatic driving without information interaction with the non-motorized vehicle. Vehicles give way, and non-motor vehicles pass through the...
