Title:
ELECTRIC VEHICLE CONTROL METHOD, AND ELECTRIC VEHICLE CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/240193
Kind Code:
A1
Abstract:
This electric vehicle control method uses a first motor (4r) and a second motor (4f) as travel drive sources, performs drive control of the first motor by transmitting a first torque command value (Tmr) to a first inverter (3r), performs drive control of the second motor by transmitting a second torque command value (Tmf) to a second inverter (3f), and performs switching control for mutually switching between an on-state in which the second inverter performs the drive control of the second motor on the basis of a requested drive force and ah off-state in which the drive control of the second motor is stopped. The purpose of the present invention is to calculate, on the basis of the rotational speed of the second motor, a torque variation (ΔT) generated in the second motor during the switching control and correct the first torque command value on the basis of the torque variation, thereby reducing a torque step generated when the drive states are switched.
