The embodiment of the present application discloses a vehicle control method, device and system. First, obtain the current vehicle speed parameter value and vehicle acceleration parameter value, that is, the vehicle actual speed value and actual acceleration parameter value. Then subtract the target speed parameter value from the vehicle speed parameter value, and input the difference into the first PID controller to obtain the target acceleration parameter value. Then subtract the target acceleration parameter value from the vehicle acceleration parameter value, and input the difference value into the second PID controller to obtain the control amount for controlling the vehicle. It can be seen that in the embodiment of the present application, the execution results of the control quantities output by the second PID controller are respectively fed back to the first PID controller and the second PID controller, and the PID controller can timely discover the target value and the second PID controller through the double feedback method. The error between the actual values ​​and the reduction of the tracking error can improve the tracking accuracy, realize the matching driving strategy according to the real-time running state of the vehicle, and improve the driving experience.
