Abstract
A vehicle includes a wheel, an electric motor that drives the wheel, a drive torque operator that is operated by an operator, a slip detection unit that detects a slipping state of the wheel, a torque command value calculation unit that calculates a torque command value for the electric motor, and a motor drive unit that drives the electric motor according to a calculated torque command value. When the slip detection unit has not detected a slipping state of the wheel, the torque command value calculation unit calculates a torque command value for the electric motor according to an input to the drive torque operator. When the slip detection unit has detected a slipping state of the wheel, the torque command value calculation unit calculates a torque command value that repeatedly fluctuates alternately between a first value not more than a torque command value at the time when wheel slip has been detected and a second value smaller than the first value.
