Title:
CONTROL METHOD FOR IMPROVING DRIVABILITY OF ELECTRIC VEHICLE IN ENERGY RECOVERY CONDITIONS
Document Type and Number:
WIPO Patent Application WO/2023/284573
Kind Code:
A1
Abstract:
A control method for improving the drivability of an electric vehicle in energy recovery conditions, comprising: step 1, a vehicle controller collects information; step 2, the vehicle controller calculates energy recovery torque according to the collected information; step 3, the energy recovery torque is converted into energy recovery power; and step 4, an allowable charging power capability value of a power battery is compared to the energy recovery for correction. When a vehicle is in a recovery condition and the allowable charging capabilities of the power battery is weak, the recovery torque at the wheel end is guaranteed to be consistent with expectations, which ameliorates the problem of the braking sensation of the whole vehicle being weakened or lost under gliding or braking conditions due to the reduction or absence of the energy recovery capabilities of the vehicle.
