A method uses the electric motor (4) of an electric vehicle to reduce vibration of the vehicle body (1). The electric motor (4) is supported on the vehicle body (1) or on the subframe (2) of the electric vehicle. The method includes determining a vibration of a subframe (2) or of the vehicle body (1) in the area of force introduction sites where electric motor (4) is supported. The method proceeds by determining a torque required to be generated by the electric motor (4) to introduce a force into the subframe (2) or into the body (1) for counteracting the force caused by the determined oscillation acting on the subframe (2) or the vehicle body (1) and adjusting at least one driving signal of the electric motor (4) such that the required torque is generated based on the change in the drive torque of the electric motor (4).
