A vehicle braking energy recovering method and apparatus is disclosed. The method includes: obtaining current location information of a vehicle; determining a current road scenario based on the current location information of the vehicle; determining the current road scenario based on a mapping relationship between a road scenario and a weight; determining a safe distance and a safe speed of the vehicle based on the weight; determining a target torque based on the safe distance and the safe speed of the vehicle; and controlling, based on the target torque, a motor of the vehicle to recover braking energy. The vehicle braking energy recovering method and apparatus can improve a braking energy recovery rate.
