Abstract: A vehicle braking energy recovering 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.

Abstract: A method for accessing a memory of a multi-core system, a related apparatus, a system, and a storage medium involve obtaining data from a system memory according to a prefetch instruction, sending a message to a core that carries the to-be-accessed data. Each segment of data is stored in an intra-core cache based on the prefetch instruction.
