Abstract

The invention provides an energy management method and system based on a steady-state engine strategy, and belongs to the technical field of hybrid automobile energy management strategies. The problemof how to optimize energy management under various actual working conditions and dynamic change requirements is solved. The method comprises the steps: obtaining the current driving working conditionof a vehicle, and obtaining a dynamic SOC balance strategy, a self-adaptive start-stop strategy, a torque distribution strategy and an economical gear shifting line strategy corresponding to the current driving working condition according to the current driving working condition; and according to the self-adaptive start-stop strategy, the torque distribution strategy and the economical gear shifting line strategy corresponding to the current working condition, conducting engine start-stop, torque distribution and gear shifting control in combination with the dynamic SOC balance strategy. Thesystem comprises a vehicle control unit, a gearbox controller, a battery management system, a motor controller and an engine controller for realizing a dynamic SOC balance strategy, a self-adaptive start-stop strategy, a torque distribution strategy and an economical gear shifting line strategy. Energy management is optimized, and the economic fuel performance is improved.

Description

technical field [0001] The invention belongs to the technical field of hybrid vehicle energy management strategies, and relates to an energy management method and system based on a steady-state engine strategy. Background technique [0002] The power system of a hybrid electric vehicle is composed of multiple power sources, and the energy management strategy can realize the reasonable distribution of required power among multiple power sources and the coordinated control among the components of the power system, so as to achieve the goal of maintaining good power performance. Under the premise, to achieve vehicle fuel economy and clean environmental protection. A particular consideration in the energy management of a vehicle is the powertrain, whose subcomponents include the engine, electric motor, battery, clutch and gearbox. And SOC is used to indicate the state of charge of the power battery. And the hybrid vehicle judges the driving conditions of the vehicle according ...
