Abstract

The embodiment of the invention provides a vehicle following method and device, and a computer readable storage medium. The vehicle following method comprises the steps: through the speed of a vehicle, the acceleration of the vehicle, the speed of a front vehicle and the acceleration of the front vehicle, the expected vehicle distance of the vehicle relative to the front vehicle is obtained; the distance difference is obtained through the expected vehicle distance and the actual vehicle distance; and the speed of the vehicle and the acceleration of the vehicle are adjusted through the distancedifference. According to the technical scheme, the speed and acceleration of the vehicle can be adjusted more accurately, thus the needs of the vehicles for safety can be met, and the traffic passageefficiency can also be improved.

Description

technical field [0001] The present invention relates to the technical field of intelligent driving, in particular to a car following method, device and computer-readable storage medium. Background technique [0002] With the rapid development of the vehicle industry and the continuous improvement of people's living standards, the proportion of cars in people's daily life is gradually increasing. Since there are more and more vehicles on the road, the driving speed of the vehicle is very slow, so the driver needs to be highly aware of the distance between the vehicle and the vehicle in front. After a long time, the driver is likely to be in a fatigue driving state, resulting in traffic accidents. As one of the key technologies of automotive safety assistance systems, automatic car-following technology has received widespread attention. The vehicle following refers to the behavior that each member vehicle in a specific vehicle group maintains a certain speed and follows behi...
