Method and device for determining driving track of automatic driving vehicle and electronic equipment

Abstract

The invention provides a method and device for determining the driving track of an automatic driving vehicle and electronic equipment, and the method comprises the steps: firstly obtaining the driving characteristics and the lane structure characteristics of a target vehicle, determining the lane changing intention of the target vehicle in a first preset time period according to the driving characteristics and the lane structure characteristics, and obtaining the driving track of the target vehicle; wherein the first preset time period is a short time period, then a driving track of the vehicle in a second preset time period is determined according to the lane changing intention, the second preset time period is a long time period, and short-time intention prediction and long-time track prediction are combined, so that the driving track of the vehicle is predicted. The finally determined driving track can accurately judge the lane changing intention of the vehicle, and can plan a more reasonable driving track for the vehicle after lane changing, so that the vehicle collision condition is avoided, and the driving safety of the automatic driving vehicle is effectively improved.

Description

technical field [0001] The present application relates to the technical field of automatic driving, and in particular relates to a method, device and electronic equipment for determining a driving trajectory of an automatic driving vehicle. Background technique [0002] With the rapid development of artificial intelligence, more companies and scientific research institutions have devoted more R&D energy to the research in the field of autonomous driving. How to plan driving routes safely and effectively is a very important research topic in the field of autonomous driving, and it is also one of the problems that need to be solved urgently. It covers all technical fields of autonomous driving, from the most basic brakes, to sensors that perceive the surrounding environment, to positioning and prediction models, etc. [0003] In the existing technology, the planning of the driving path of the autonomous vehicle is mainly to make judgments on the driving trajectory of about 4 ...

Problems solved by technology

[0004] However, the short-sequence trajectory prediction method has a short predicted trajectory, and it is difficult to make predictions for longer-term trajectories, while the long-sequence trajectory prediction method is difficult to rule out the coincidence between the obstacles' trajectories, and cannot ensure that the vehicle and the obstacle no collision
