Abstract
A method, device and system for controlling a vehicle passing through an intersection are provided. The method includes generating a reference running track based on coordinate of first road from which the vehicle is to leave and coordinate of second road into which the vehicle is to enter. The first road and the second road intersect at the intersection through which the vehicle is to pass. The method further includes generating, in real time, a preview track of vehicle based on coordinate of centroid of the vehicle, course of the vehicle and coordinate of the second road, comparing the preview track with the reference running track and acquiring running speed limit and turning angle of the vehicle based on the comparing, and controlling the vehicle to run at the turning angle and a running speed less than or equal to the running speed limit.
