Title:
ELECTRIC VEHICLE CONTROL METHOD, AND CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/100268
Kind Code:
A1
Abstract:
This method for controlling an electric vehicle is a method for controlling an electric vehicle in which a winding field synchronous motor 4, provided with a rotor having a rotor winding and a stator having a stator winding, serves as a drive source, wherein a stator current flowing through the stator winding and a rotor current flowing through the rotor winding are controlled. In this control method: a basic torque command value is set on the basis of vehicle information; a d-axis current command value and a first q-axis current command value with respect to the stator current, and an f-axis current command value with respect to the rotor current are calculated on the basis of the basic torque command value and the vehicle information; a magnetic flux estimated value, which is an estimated value of magnetic flux generated in the rotor, is calculated on the basis of the d-axis current command value and the f-axis current command value; a final torque command value is calculated on the basis of the first q-axis current command value and the magnetic flux estimated value; and a second q-axis current command value is calculated on the basis of the magnetic flux estimated value and the final torque command value. Furthermore, the stator current and the rotor current are controlled on the basis of the second q-axis current command value, the d-axis current command value, and the f-axis current command value.
