Abstract

The embodiment of the invention discloses an unmanned vehicle control method, apparatus and device and a storage medium. The method comprises the steps of: determining the speed of a vehicle and the current position of the vehicle; determining the deviation of the current position relative to a set driving path; determining a PID parameter set corresponding to the speed of the vehicle; inputting the PID parameter set and the deviation into the PID controller to obtain output PID control amount; and according to the PID control amount, determining the control angle of a steering wheel in the vehicle, and outputting the control angle to the steering wheel. The technical scheme provided by the embodiment of the invention can reduce the overshoot or following errors of the vehicle in differentspeeds and is more accurate and stable for vehicle control.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicles, and in particular to a control method, device, equipment and storage medium for an unmanned vehicle. Background technique [0002] Proportion-integral-derivative (PID) control is one of the earliest control strategies developed using classical control theory. Due to its simple algorithm, good robustness and high reliability, it is widely used in industrial processes and A good control effect has been achieved. With the development of industry, PID control is applied to the control system of vehicles, especially in the control system of unmanned vehicles. [0003] In the prior art, when the PID control method is used to control the unmanned vehicle to follow the set travel route, it is easy to cause the vehicle to deviate from the set travel route, resulting in an unsatisfactory control effect.
