Abstract

The invention relates to the technical field of hybrid electric vehicle control, in particular to a plug-in hybrid electric vehicle engine starting request control system and method. The electric energy system starting request module is used for acquiring an engine starting request condition in the aspect of an electric energy system; the transmission part starting request module is used for acquiring an engine starting request condition in the aspect of a transmission part; the driver starting request module is used for acquiring an engine starting request condition of a driver; the external condition starting request module is used for acquiring an engine starting request condition in the aspect of external conditions; and the starting request coordination module performs starting control on the engine according to the engine starting request condition. The engine starting control method is simple and covers a wide range of working conditions, engine starting control requirement judgment is set according to the working conditions, diversified working modes and driving working conditions of the hybrid electric vehicle are met, and meanwhile the dynamic property, comfort, emission and safety performance of the whole vehicle are improved.

Description

technical field [0001] The invention relates to the technical field of hybrid vehicle control, in particular to a plug-in hybrid vehicle engine start request control system and method. Background technique [0002] The development of new energy vehicles has become unstoppable. Plug-in hybrid vehicles not only respond to the national call for energy conservation and emission reduction, but also solve users' mileage anxiety, and will occupy a place in the future automotive field for a long time. Plug-in hybrid electric vehicles not only have multiple power sources such as engine and drive motor, but also have a complete set of charging system, which can realize multiple working modes such as pure electric, hybrid, sports and even four-wheel drive. Compared with traditional cars, the working conditions of the engine have changed greatly. During the process of multiple working modes and their mutual switching, the timing of starting the engine directly affects the power, comfort...
