Lane changing method and device in high-speed cruise state and automobile

Abstract

The invention discloses a lane changing method and device in a high-speed cruise state and an automobile. The lane changing method comprises the steps that state information and speed limiting information of the automobile and state information of a front automobile are obtained; judging whether the speed information is smaller than the speed limiting information; if yes, determining whether the first distance information is smaller than a preset first distance threshold value or not, and if the first distance information is smaller than a preset first distance threshold value, acquiring first state information of a first vehicle on a target lane and second state information of a second vehicle on the target lane, wherein the first vehicle is a vehicle closest to the vehicle within a preset second distance threshold value in front of the vehicle on the target lane, and the second vehicle is a vehicle closest to the vehicle within a preset third distance threshold value behind the vehicle on the target lane; and controlling the vehicle to change lanes to the target lane according to the first state information, the second state information and the current speed information. Decision logic similar to manual driving is adopted, the decision process is simplified, and the decision process is simple and easy to implement.

Description

technical field [0001] The invention relates to the field of vehicle safety monitoring, in particular to a lane changing method, device and vehicle in a high-speed cruising state. Background technique [0002] In recent years, due to the development of artificial intelligence technology, automatic driving has gradually become a hot topic. Many enterprises and universities at home and abroad have started research, which has promoted the rapid development of automatic driving technology. In the autonomous driving technology, the vehicle's autonomous lane change is an important measure to ensure driving safety, and it is also one of the important research contents of the autonomous driving technology. Specifically, in the process of driving, in order to pursue a safer driving environment, higher traffic efficiency, and a more relaxed driving space, vehicles often need to perform autonomous lane changes. Before a vehicle changes lanes, it is necessary to comprehensively evaluat...
