Abstract

The invention discloses a power system for a hybrid automobile. The power system for the hybrid automobile comprises an engine, a gear, a single clutch and a motor, wherein the single clutch is arranged between the engine and the gearbox; and the motor works as an electric motor or a power generator, wherein the power system has the operation modes of an unpowered mode, a pure electric driving mode, a parallel driving mode and a parking charging mode; in the pure electric driving mode, a clutch is disconnected, the power is input into a motor auxiliary input shaft of the gearbox by the motor which works as the electric motor, and the power is output from an output shaft of the gear through the motor auxiliary input shaft and an output shaft of the gearbox; in the parallel driving mode, the complete automobile is driven by the motor, which works as the electric motor, and the engine; and in the parking charging mode, the complete automobile is static, the engine works, the clutch is closed, the engine transmits the power to a motor shaft of the motor through the gearbox, and a power cell of the hybrid automobile is charged by the motor which works as the power generator.

Description

technical field [0001] The invention relates to a hybrid electric vehicle and its power system, suitable for plug-in and non-plug-in hybrid vehicles. Background technique [0002] Hybrid electric vehicles are an important branch of new energy vehicles. Due to their combination of low emissions from electric drives and long battery life from fuel-driven vehicles, they have the best market prospects at this stage. Different from internal combustion engine vehicles and pure electric vehicles, hybrid vehicles are driven by two power sources. The characteristics of this dual power source increase the flexibility of system design. Under the coordinated control of the vehicle energy management system, the dual power source can be combined in a variety of optimized ways to form different power system working modes to adapt to different driving conditions. condition. At the same time, dual power sources also increase the complexity of the hybrid system. How to switch between multip...
