Abstract

The invention provides a parallel series type hybrid power driving system and a driving method, the engine of the driving system is connected coaxially with an ISG motor, the output shaft of the ISG motor is connected with a manual dry type clutch, the rear end of the clutch is connected with a manual gear box, the motor performs moment coupling by the coupling mechanism and the output shaft of the gear box. The driving method comprises a pure electric driving mode, a series connection driving mode, an engine driving mode, a parallel driving model, a walking vehicle charging mode, a parking charging mode and a regeneration brake energy feedback mode. The technical proposal keeps traditional vehicular structure at the max extent, and utilizes double-motor to perform optimization of working points of engine, so that the engine can run stably in high-efficiency low-emission area. The invention is particularly suitable for urban low-speed bus operation in working condition.

Description

technical field [0001] The invention relates to a system in the field of mechanical technology and a driving method thereof, in particular to an automobile hybrid driving system and a driving method thereof. Background technique [0002] A hybrid vehicle is a vehicle that is jointly driven by an engine and an electric motor system. The engine can be an internal combustion engine using a variety of fuels; the motor can be either a permanent magnet motor or an excitation motor, a synchronous motor or an asynchronous motor; the clutch can be a manual clutch or an electronically controlled automatic clutch; the gearbox It can be either a manual transmission or an automatic transmission. For hybrid vehicles with manual gearbox and manual clutch, since the engine is directly connected to the drive shaft through the clutch and gearbox, the vehicle cannot realize pure electric drive mode and series drive mode. Under public transport conditions), it is impossible to optimize the mi...
