Abstract

The invention provides a vehicle following control method, device and equipment and a readable storage medium, and the method comprises the steps: detecting a first distance between a vehicle and a target front vehicle when the vehicle is in an activated state of following and parking the target front vehicle and the speed of the vehicle is smaller than a speed threshold value; when the first distance is larger than a preset distance, the first distance is input into a creeping driving curve formula, and the target vehicle speed of the vehicle is obtained; acquiring the actual vehicle speed of the vehicle, and inputting the actual vehicle speed and the target vehicle speed into a PID algorithm to obtain a target acceleration; and controlling the vehicle speed according to the target acceleration. According to the invention, it is ensured that the vehicle has a relatively accurate following and parking distance when following and parking the vehicle in front of the target, and the driving comfort of a driver is improved at the same time.

Description

technical field [0001] The present invention relates to the field of intelligent driving, in particular to a car following control method, device, equipment and readable storage medium. Background technique [0002] In the existing ACC adaptive cruise system and TJP traffic jam assist system, the distance from the car before stopping is an important indicator. Among them, the following distance is related to many factors, such as the speed at which the main vehicle starts to brake, the distance from the vehicle in front when it starts to brake, the delay of the actuator, and the road surface conditions. In the existing follow-up scheme, the target deceleration is mainly obtained by calculating the target distance and the target relative vehicle speed until the vehicle stops. Considering the influence of factors such as obstacle recognition problems, actuator delays, and road distance conditions, it cannot guarantee that the vehicle will have an accurate parking distance whe...
