The speed v of a motor driven body, the rotational speed ω and the actual torque value Tm generated by the motor are acquired. Subsequently, unit (741) estimates the slip rate X of the drive wheels based on the movement speed v and the rotation speed ω. Further, unit (742) estimates the drive torque Td based on the rotational speed w and the actual torque value Tm. Next, unit (743) calculates a limit value L for a torque command value Tc based on the slip rate X and the drive torque Td. Further, unit (744) limits the torque command value Tc using the limit value L, generates a torque setting value Ts, which is sent to a motor drive system (900). As a result, it is possible to quickly realize control in accordance with changes in the road surface state, thus allowing safe travel while ensuring the needed drive power.
