PROBLEM TO BE SOLVED: To obtain an electric vehicle control device capable of driving a motor in a state of higher tangential force (adhesion and frictional force) of a wheel and a rail.SOLUTION: An electric vehicle control device includes: a motor torque command value acquisition unit; a sliding velocity calculation unit 2; a first correction units 42c and 43; and a second correction units 41, 42b, 42c and 43. The motor torque command value acquisition unit acquires a motor torque command value responding to an input command value based on a rotational speed of a motor that drives a wheel and an operation input. The sliding velocity calculation unit 2 calculates the sliding velocity to the rail of the wheel based on the rotational speed and the vehicle speed of the wheel. First correction units 42c and 43 correct the acquired motor torque command value according to the calculated sliding velocity. Second correction units 41, 42b, 42c and 43 correct the acquired motor torque command value to approach the maximum value of the torque corresponding to the velocity, according to the time variation of the torque of the motor and the time variation of the sliding velocity. |
