Title:
DEVICE FOR CONTROLLING ELECTRIC AUTOMOBILE
Document Type and Number:
WIPO Patent Application WO/2014/188963
Kind Code:
A1
Abstract:
Provided is a device for controlling an electric automobile that can precisely control the torque of a vehicle-wheel-driving motor in an electric automobile. This electric automobile is provided with a motor (6), an ECU (21), and an inverter device (22). A motor control unit (29) of the inverter device (22) has a parameter map for storing motor parameters, an open loop control unit (37) for using the parameters stored in the parameter map to produce a control amount for a torque command from the ECU (21) through open loop control according to a voltage equation, a current feedback control unit (38) for performing control for eliminating deviation in the command current value produced in the inverter for the torque command from the ECU (21), and a hybrid control unit (39) for controlling the motor (6) according to a control amount produced from the control amount produced by the open loop control unit (37) and the control amount produced by the current feedback control unit (38).
