Engine starting control system and method of hybrid vehicle and vehicle

Abstract

The invention provides an engine starting control system and method of a hybrid vehicle and a vehicle and relates to the technical field of vehicles. Specifically, the engine starting control system of the hybrid vehicle comprises an electric driving system, a fuel driving system, a detection system and a vehicle controller, wherein the electric driving system is used for driving a first driving shaft of the vehicle; the fuel driving system is used for driving a second driving shaft of the vehicle; the detection system is used for detecting information and working conditions inside and outsidethe vehicle; and the vehicle controller is configured to control a first starting mode or a second starting mode to start an engine according to different information and working conditions of the vehicle during starting the engine. According to the engine starting control system and method of the hybrid vehicle and the vehicle, by directly using an existing electric driving system and an existing fuel driving system of the hybrid vehicle, the engine is started by using different modes so as to furthest develop advantages of a vehicle power system configuration; on the premise of not increasing additional parts, an effect similar to ISG or BSG starting is achieved, and purposes of short starting time and oil saving are realized.

Description

technical field [0001] The invention relates to the technical field of vehicle engines, in particular to an engine start control system and method of a hybrid vehicle and the vehicle. Background technique [0002] With the advancement of science and technology and the increasingly stringent requirements for fuel consumption regulations in various countries, major auto companies around the world have increased their investment in research and development of new energy vehicles. Hybrid vehicles have been paid more and more attention by various car companies because they solve the mileage anxiety problem of pure electric vehicles and reduce the fuel consumption of vehicles. Among them, one axle is driven by a traditional engine + gearbox, and the other axle is driven by an electric motor. The multi-axle drive hybrid vehicle has the advantages of low technical difficulty in development and good platform expandability. [0003] The engine starting control methods of hybrid elect...
