CONTROL DEVICE FOR ELECTRIC VEHICLE

摘要

In this control device for an electric vehicle, a motor control unit (29) performs torque control by vector control of a motor (6) in accordance with a torque command map in which the relationship between a torque command that serves as an acceleration/deceleration command and a current command for the motor (6) is defined. The control device for an electric vehicle is provided with: a motor temperature detection means (Sc) that detects the temperature of the motor (6); an oil temperature detection means (Sd) that detects the temperature of oil for cooling the motor (6); and a torque command map automatic switching unit (34) that switches the torque command map in accordance with a set rule in response to the temperatures detected by the aforementioned detection means. The torque command map that is switched by the torque command map automatic switching unit (34) is a map in which the d-axis current in the vector control increases as the temperature of the motor (6) and/or the temperature of the oil decreases.
