Abstract

The invention discloses an automatic driving method and device and a vehicle. The method comprises the following steps: detecting a traffic signal at an intersection in the driving direction of the vehicle; determining a path from the vehicle position to a target position of the intersection; applying different acceleration curves to the path to obtain different trajectories corresponding to the path, wherein the trajectories comprise speed and time of each position in the path; according to the state indicated by the traffic signal, selecting a driving model corresponding to the traffic stateof the intersection; selecting a trajectory matched with the vehicle speed from the different trajectories; and according to the selected trajectory, carrying out at least one slow-down driving process and at least one constant speed driving process on the path, and then, reaching the intersection. The method can control the vehicle to drive safely and stably under the environment comprising theintersection.

Description

technical field [0001] The invention relates to automatic driving technology, in particular to an automatic driving method and device, and a vehicle. Background technique [0002] As a typical application mode of artificial intelligence in the next technological era, autonomous driving technology is receiving unprecedented attention. [0003] The actual driving environment of the vehicle is complex and diverse. Taking the road driving in China as an example, the vehicle driving needs to refer to Article 45 of the Implementation Regulations of the Road Traffic Safety Law: [0004] Motor vehicles on the road shall not exceed the speed indicated by the speed limit signs and markings. On roads without speed limit signs or markings, motor vehicles shall not exceed the following maximum driving speeds: [0005] (1) For roads without a road centerline, 30 kilometers per hour for urban roads and 40 kilometers per hour for highways; [0006] (2) For roads with only one motor vehic...
