ELECTRIC MOTOR VEHICLE CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To perform optimum control depending on the type of a motor driven by automatically determining the type even if the motor connected to an inverter is of any type.

SOLUTION: This electric motor vehicle control device drives the motor 3 for driving an electric motor vehicle with an inverter device composed of an inverter main circuit 1 and an inverter control section 2 and comprises a motor type determining device 6 for determining the type of the motor 3 connected with the inverter device, and a control parameter setting section 7 for setting a control parameter which is determined by the motor type determination device and which is in accordance with the motor type currently connected to the inverter device. The motor type is determined based on a current value obtained when a predetermined voltage is applied to the motor or a voltage value obtained when a predetermined current is passed through the inverter device.
