Abstract

The invention is suitable for the field of control technology, and provides a method, a device, and equipment for vehicle energy management, and a storage medium. The method comprises: firstly, detecting whether a vehicle is in a parking state, when the vehicle is detected to be in a parking state, obtaining reference work condition information determined for the vehicle in advance and corresponding control parameters, according to the reference work condition information and the control parameters, obtaining an energy management scheme of a next travelling road section of the vehicle, detecting whether the vehicle is in a travelling state, when the vehicle is detected to be in the travelling state, according to the energy management scheme, executing corresponding management operation ona preset position of the next travelling road section. Thus, precision of energy management on a hybrid power vehicle using a Pontryagin minimum principle is improved while reducing calculated amount,so as to improve management efficiency of vehicle energy.

Description

Technical field [0001] The invention belongs to the field of control technology, and in particular relates to a vehicle energy management method, device, equipment and storage medium. Background technique [0002] Since hybrid vehicles use more than two power sources, their energy management is particularly important for energy-saving driving. Currently, there are two main types of energy management strategies for hybrid electric vehicles: the first type is energy management strategies based on heuristic concepts, and the second type is energy management strategies based on optimal control theory. The former appeared in the early research on hybrid electric vehicles. At present, most hybrid electric vehicles on the market adopt this type of energy management strategy. This type of strategy is relatively simple to implement, but when applying this type of strategy, it is difficult for the fuel economy of hybrid vehicles to achieve the optimal goal, and there is still room for imp...
