A torque control of an in-vehicle motor is performed in consideration of a slip prevention control. Filtering processing is performed by a first filter processor on a high-order torque command value from a high-order device, and filtering processing is performed by a second filter processor on an angular velocity detected by an angular velocity detector. A driving torque command value to drive an electric motor is calculated based on filtering processing results. Each of the filter processors changes a time constant of the filtering processing according to a road surface friction coefficient as disturbance information.
