DRIVE
July 13, 2016
Provided is a control device for an electric vehicle which control device outputs a desired motor torque even when a problem due to aged deterioration like arises in a traction motor of the electric vehicle. The control device includes an ECU (21) and an inverter device (22) including: a power circuitry (28) including an inverter (31); and a motor control unit (29). A rotation angle sensor (36) detecting a rotation angle of a motor (6) is provided, The circuitry (29) receives a rotation angle of the motor (6) from the sensor (36) to perform control in accordance with the rotation angle of the rotor, the control being based on a torque command mapping table (35) in which a relationship between a rotation speed and a torque of the motor is defined. The circuitry (29) includes an adjustment module (38) adjusting the table with respect to: a torque command from the ECU (21) and a speed of the vehicle.
