Vehicle control method, device and vehicle

Abstract

The present disclosure relates to a vehicle control method, device, and vehicle. The method includes: first acquiring driving environment information of the self-driving vehicle; then generating planning speed information according to the driving environment information; and then generating planning speed information according to the planning speed Information to determine the driving mode of the self-driving vehicle within a preset time period or a preset distance; finally output corresponding power control information according to the driving mode. The present disclosure can combine the characteristics of the vehicle with the driving mode of the self-driving vehicle within the preset time or distance as the control basis, avoid the problem of sudden acceleration changes, realize smooth transitions between acceleration, constant speed, and deceleration, and achieve smooth accelerator and Braking control; it can effectively improve the comfort of driving an autonomous vehicle in a dynamic urban traffic environment.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle control, and in particular, to a vehicle control method, device and vehicle. Background technique [0002] Self-driving cars generally include perception, decision-making, control and other links, in which the control link is divided into horizontal control and vertical control. Traditional vehicle longitudinal control methods are generally model-based control methods, such as pole allocation, optimal control and other methods. With the deepening of research on the control system of autonomous driving vehicles, control methods such as fuzzy control, neural network control, PID (Proportion Integration Differentiation, proportional integral differential) control and MPC (Model predictive control, model predictive control) control have also been widely used. In the process of controlling the self-driving car. Through the research and analysis of the above control methods, it is concluded t...
