Zusammenfassung:A control device includes a torque setting section for setting a target output torque of an electric motor based on a driving state including an accelerator operation amount; a non-transmission state determiner section for determining whether a driving power transmission path is in a non-transmission state in which driving power is not permitted to be transmitted from the electric motor to a drive wheel or in a transmission state in which the driving power is permitted; and a torque compensation section for compensating the target output torque, when the non-transmission state determiner section determines that the driving power transmission path is in the non-transmission state. The torque compensation section compensates the target output torque by using a slowness characteristic in which a change in the motor rotational speed which occurs with time is slower when in the non-transmission state than when in the transmission state.
