Title:
CONTROL METHOD AND CONTROL DEVICE FOR ELECTRIC FOUR-WHEEL DRIVE VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/074717
Kind Code:
A1
Abstract:
This control method for an electric four-wheel drive vehicle is provided with a front drive source for driving front wheels and a rear drive source for driving rear wheels independently of the front wheels. The control method drives one of the front wheels and the rear wheels with a smaller driving force than a fundamental driving force in such a way that: the driving direction of the electric four-wheel drive vehicle is obtained on the basis of the input state of a shift lever; the actual moving direction of the electric four-wheel drive vehicle is obtained; when the driving direction and the moving direction are different from each other, the fundamental driving force for suppressing movement to the moving direction is set in the front wheels and the rear wheels; and a limit for setting an upper limit value for the driving force generated in one of the front wheels and the rear wheels is implemented.
