To detect entry of a drive wheel into a road surface high resistance portion at earlier timing.SOLUTION: An electric vehicle includes a motor connected to drive wheels and a control unit for controlling the motor on the basis of a torque command of the motor. The control unit determines whether or not the drive wheel enters a road surface high resistance portion, while using at last one of a rotational angular velocity of the motor, a rotational angular acceleration of the motor, a rotational angular velocity of the drive wheel and a rotational angular acceleration of the drive wheel, and the torque command. Accordingly, when the drive wheel enters the road surface high resistance portion, the entry can be detected at earlier timing.SELECTED DRAWING: Figure 2

    【課題】駆動輪が路面高抵抗部に進入したときに、その進入をより早いタイミングで検知する。【解決手段】駆動輪に接続されたモータと、モータのトルク指令に基づいてモータを制御する制御装置と、を備える電動車両において、制御装置は、モータの回転角速度、モータの回転角加速度、駆動輪の回転角速度、駆動輪の回転角加速度のうちの少なくとも1つと、トルク指令と、を用いて駆動輪が路面高抵抗部に進入したか否かを判定する。これにより、駆動輪が路面高抵抗部に進入したときに、その進入をより早いタイミングで検知することができる。【選択図】図2
