| description | The invention belongs to the technical field of electric vehicle speed limiting control, and particularly relates to an electric vehicle speed limiting control method, device and system. According to the method, the feedforward control thought is applied to speed limiting control of the electric vehicle, when the vehicle is in a downhill speed limiting mode of a driving mode or a sliding mode, driving feedforward torque/braking feedforward torque is obtained through corresponding calculation, and the driving feedforward torque/braking feedforward torque is added to closed-loop output torque to obtain driving limiting torque/braking output torque; the smaller value of the driving limiting torque and the driving demand torque of the driver is taken as the driving command torque, or the braking output torque is taken as the braking command torque, so that the limitation of the maximum vehicle speed in the driving mode is realized and no power loss exists; in the downhill speed limiting mode in the sliding mode, |
