摘要： An electric vehicle includes a slip ratio estimator that estimates a slip ratio based on rotational frequencies of respective driven and drive wheels. The vehicle also includes a disturbance observer that determines an estimate of a torque attributable to external force. The vehicle also includes an estimator that may estimate an entire torque to the drive wheel, based on a motor torque command value and the estimate of torque. The vehicle also includes an estimator that estimates a coefficient of friction between a road surface and a tire, based on the entire torque and the slip ratio. The vehicle also includes a determiner that determines a maximum acceptable torque Tmax, based on the coefficient of friction and a vertical load component. Torque limitation is performed such that the motor torque command value does not exceed the maximum acceptable torque Tmax.
