Abstract

This invention relates to a kind of controlling method to reduce rotation speed fluctuation of the mixed power vehicle engine when idling generating electric power. The whole car controller is electric connected to other components. The mixed power system electric power generation operating mode is split into engine driven running state and non-engine driven running state. According to the different state, controller uses different power generation load adjusting speed to change the generator and engine load synchronously.

Description

technical field [0001] The invention relates to a control method for a power system of a hybrid electric vehicle, in particular to a control method for reducing fluctuations in rotational speed of an engine of a hybrid electric vehicle when idling to generate electricity. Background technique [0002] With the increasingly prominent global environmental and energy issues, the development of new vehicles with low emissions and low fuel consumption has become the primary task of the development of the automotive industry today. Hybrid electric vehicle technology avoids the shortage of battery technology and energy infrastructure of pure electric vehicles. It is a good solution to current problems and has become a hot spot in international automotive research and development. [0003] It is necessary to ensure the life of the battery itself and the performance of the whole vehicle by generating electricity at idle speed of the engine of the hybrid electric vehicle to replenish ...
