Title:
ELECTRIC VEHICLE CONTROL METHOD AND ELECTRIC VEHICLE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/089848
Kind Code:
A1
Abstract:
An aspect of the present invention is an electric vehicle control method which distributes required torque between front torque and rear torque and which has a reduced power consumption mode and a driving performance mode as control modes for adjusting the distribution of the required torque. In this electric vehicle control method, in the case of the reduced power consumption mode, the required torque is largely distributed to one of either the front torque or the rear torque, while in the case of the driving performance mode, the front torque or the rear torque to which the required torque is largely distributed in the reduced power consumption mode is reduced. Also, the temperature of a front drive system or a rear drive system is obtained, and the output of the front or rear torque is limited by setting an upper limit value on the distributed front or rear torque according to the temperature of the front or rear drive system. Additionally, when the control mode is the reduced power consumption mode, after the upper limit value is lowered, the control mode is switched to the driving performance mode before the output of the front or rear torque is limited to the upper limit value.
