ELECTRIC-VEHICLE CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electric-vehicle control device, with which a torque characteristic in control in the vicinity of zero speed is improved.SOLUTION: According to an embodiment, the electric-vehicle control device includes: an inverter that outputs AC power to an induction motor that is a power source of an electric vehicle; AC current detection means for detecting AC current output from the inverter; disturbance torque estimation means for estimating a disturbance torque of the induction motor on the basis of the AC current detected by the AC current detection means; rotor angle frequency estimation means for estimating a rotor angle frequency of the induction motor on the basis of a current command value for the AC current output from the inverter and the disturbance torque estimated by the disturbance torque estimation means; and inverter control means for controlling the inverter on the basis of the rotor angle frequency estimated by the rotor angle frequency estimation means and the current command value.
