Title:
ENERGY RECOVERY CONTROL METHOD AND DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/077885
Kind Code:
A1
Abstract:
An energy recovery control method comprises: determining whether a vehicle satisfies an activation condition for entering a preset high-speed coasting mode, the high-speed coasting mode being used to show a working condition in which the speed of the vehicle is greater than or equal to a preset first speed threshold and the driver has no obvious braking requirement; and controlling the vehicle to perform an energy recovery cancellation operation when the vehicle enters the high-speed coasting mode. Said method considers energy recovery management from the perspective of the intention of a driver, and in a high-speed coasting mode, recognizes that the driver currently has no strong braking intention, and cancels energy recovery, reducing fuel consumption, achieving better driver intention recognition, and improving comfort during the coasting of a vehicle. The present invention also relates to an energy recovery control device.
