Abstract

The invention discloses a vehicle control method, device and equipment, a vehicle and a medium, and relates to the technical field of intelligent transportation. According to the specific implementation scheme, determining dead zone parameters during vehicle driving, wherein the dead zone parameters at least comprise a driving dead zone parameter and a braking dead zone parameter; determining a target compensation strategy according to an initial acceleration in driving planning and the dead zone parameter; compensating the initial acceleration according to the target compensation strategy toobtain a target acceleration; and controlling the vehicle to run according to the target acceleration. According to the embodiment of the invention, the target compensation strategy is determined by introducing the dead zone parameters; therefore, the initial acceleration in the driving plan is compensated based on the target compensation strategy, the initial acceleration is compensated to different degrees under different conditions, the dynamic determination of the target acceleration is realized, the dynamic control of the driving process of the vehicle is further realized, and the effectof considering both the service life and the driving safety of the vehicle is achieved.

Description

Technical field [0001] This application relates to data processing technology, in particular to the field of intelligent transportation technology, and in particular to a vehicle control method, device, equipment, vehicle and medium. Background technique [0002] In the prior art, when controlling the driving process of an unmanned vehicle, the driving process of the vehicle is usually planned and controlled according to the driving environment of the vehicle and the driving task of the vehicle. When controlling the driving process of the vehicle according to the plan, the movement of the vehicle is directly controlled according to the acceleration parameters generated by the plan. [0003] However, in the above-mentioned method, the vehicle will frustrate and travel in scenarios such as normal vehicle acceleration and deceleration, which affects the service life of the vehicle; and in the case of overtaking or obstacle avoidance, the acceleration and deceleration may not be timely...
