Passing method for self-driving vehicle at intersection without signal light

Abstract

The invention discloses a passing method for a self-driving vehicle at an intersection without a signal light. The method is executed by a vehicle-mounted actuator, and comprises steps: whether a target vehicle exists in other directions of the intersection is firstly judged; if yes, judgment is performed according to types of the vehicle and the target vehicle; and judgment is then performed according to whether the danger of collision exists to the vehicle and the target vehicle; and whether the vehicle can pass is thus determined. The danger of collision happening to the self-driving vehicle at the intersection without the signal light can be avoided, and safe passing of the vehicle can be ensured.

Description

technical field [0001] The invention relates to the field of road traffic safety, in particular to a method for passing an automatic driving vehicle at an intersection without signal lights. Background technique [0002] Usually, the self-driving vehicle will recognize the information of the traffic lights when passing the intersection to drive according to the traffic rules. The self-driving car obtains the status, phase and other information of the signal lights through the camera installed on the car or the vehicle communication terminal (ie OBU); but in the future At intersections equipped with traffic lights, self-driving vehicles cannot obtain clear passing instructions, and there is a risk of collision with vehicles coming from other directions at the intersection. [0003] The usual way to solve this problem is to install a roadside communication terminal (RSU) at the intersection, and the self-driving vehicle can efficiently pass through the intersection according t...
