Abstract

The invention discloses a vehicle multi-energy control method, system and device, and a storage medium. A dynamic property objective function and a system equivalent fuel consumption economic performance objective function are solved; a long-time-domain oil consumption optimization problem of a hybrid power system can be effectively coordinated; and meanwhile, short-time-domain safe driving and dynamic response characteristics are guaranteed, the hybrid power system is optimized in real time in a multi-time-scale mode, and on the premise that the driving safety is considered, power responsiveness and fuel economy of a hybrid power off-road vehicle are improved. The method, the system, the device and the storage medium can be widely applied to the technical field of vehicle control.

Description

technical field [0001] The present invention relates to the technical field of vehicle control, in particular to a vehicle multi-energy control method, system, device and storage medium. Background technique [0002] With the rapid development of the automobile industry all over the world, automobiles not only bring convenient transportation environment and high traffic efficiency to human beings, but also bring negative impacts that cannot be ignored to human beings, society and nature, among which the continuous consumption of resources and The deterioration of the natural environment has become the most prominent problem. Among the types of new energy vehicles, electric vehicles are considered to be one of the main development directions of new energy vehicles. However, under the current technical conditions, the energy density and power density of power batteries need to be improved, and the mileage of power batteries cannot meet long-distance driving across regions. ne...
