Abstract

The invention provides a control method, device and equipment for automatic drive of a vehicle and a readable storage medium. The method includes the steps that according to the position information of an obstacle at the current moment, the motion track of the obstacle within the preset time period in the future is determined by a trained prediction model; the traveling track of the vehicle withinthe preset time period in the future is calculated according to traveling data of the vehicle at the current moment; and according to the motion track of the obstacle and the traveling track of the vehicle within the preset time period, whether the obstacle enters an unsafe area of the vehicle within the preset time period in the future or not is predicted, and if the obstacle enters the unsafe area of the vehicle within the preset time period, safety control is carried out on the vehicle. Prediction of the risk of collision between the vehicle and the obstacle within the preset period in thefuture is realized, when the risk of collision between the vehicle and the obstacle is predicted, safety control is carried out the vehicle in advance, the reaction time of the upper logic can be prolonged, and the safety of automatic drive is improved.

Description

technical field [0001] The present invention relates to the technical field of automatic driving, in particular to a control method, device, equipment and readable storage medium of an automatic driving vehicle. Background technique [0002] The current automatic driving safety detection detects obstacles in the current surrounding environment of the vehicle in real time, such as passing vehicles, pedestrians and other obstacles, and performs upper-level logical vehicle safety control according to the distance between the current obstacles and the vehicle. [0003] However, since obstacles are often in motion relative to the vehicle, in the actual driving process of the vehicle, although there is still a certain distance between the obstacle and the vehicle, the obstacle and the vehicle may be close to each other or even about to collide . In the prior art, the vehicle safety control of the upper-level logic is carried out according to the distance between the obstacle and ...
