The invention provides a torque control method, a motor controller, a vehicle control unit and an electric vehicle, and relates to the technical field of vehicle control. The method comprises the steps: determining a current vibration signal of a driving system according to the rotating speed of a motor; determining an active damping vibration coefficient and an active damping compensation coefficient of a driving system according to the current vibration signal; sending the active damping vibration coefficient and the active damping compensation coefficient to a vehicle control unit; according to the current vibration signal, the active damping compensation coefficient and a received active damping control exit coefficient sent by the vehicle control unit, adjusting the currently received demand torque, wherein the active damping control exit coefficient is determined according to the active damping vibration coefficient and the active damping compensation coefficient. According to the scheme, the vibration problem caused by underdamping in the working process of the driving system is eliminated, and the driving feeling of a user is improved.
