Description
Technical field:
The present invention relates to the coaxial-type parallel-connection structure hybrid power system for automobile of a kind of magnetic couple and blending means.
Background technology:
In recent years, motor vehicle exhaust gases discharges one of oneself important source becoming urban atmospheric pollution. The most high thermal efficiency of petrol engine is about 33%, and the region more than 30% is exactly the restricted work area of engine. Currently, in automobile dynamic system, the 13% of fuel energy is for travelling, and remaining 87% is used as and drives accessory and become thermal losses and be diffused in air. Meanwhile, due to the urban traffic conditions day by day blocked up, cause motor car engine to be operated in the off-design points such as the lower slow speed of revolution of efficiency for a long time, not only exacerbate automobile energy consumption, and the discharge of noxious pollutant constantly increases, cause urban air environment constantly severe. Considering that the pollution of environment, the cry of environmental protection and energy saving is grown to even greater heights by a large amount of consumption, the orthodox car exhaust emissions of the Nonrenewable resources such as oil, research environmental protection, energy-efficient automobile dynamic system is very urgent.
Hybrid power system has more than one energy transformation modes to provide the system driving power. Hybrid power system adopts suitable fuel reburning device (such as oil engine), energy storage device and electric motor as hybrid power source, under tight control strategy controls, fuel reburning device, energy storage device and motor is made to be operated in high-level efficiency, low emission zone as far as possible under driving operating mode. Thus greatly improve the fuel-economy performance of automobile when different operating mode travels, exhaust emissions performance and other use propertieies.
Hybrid vehicle combines the advantage of traditional combustion engine automobile and electromobile, and course continuation mileage is unrestricted, and change for orthodox car is little, and the input that industrialization is produced compares fuel cell car also much less.

Its advantage of series system is that the operation of engine is independent of the speed of a motor vehicle and road condition, engine operation state is not by the impact of automobile running working condition, running under the state that can remain on stable, efficient, low stain, engine has good economy and low discharge index. Shortcoming is in the conversion process of energy of the heat energy-electric energy-mechanical energy in the series system of Engine-Generator-drive motor, transmission ofenergy loss is bigger, also there is energy waste in the charge and discharge process of power battery pack, the total overall efficiency of energy transformation is lower than internal-combustion engines vehicle.
In parallel system, engine and electric motor separately can provide power to automobile driving wheel, there is no the generator in tandem HEV power train, the mechanical energy of engine can directly output to automobile drive axle, centre does not have the conversion of energy, compared with arranging with tandem, system efficiency is higher, and fuel oil consumption is also less. But owing to there being direct mechanical connection between engine and driving wheel of vehicle, engine operation condition is inevitably subject to the impact of the concrete driving cycle of automobile.
What combined hybrid system was tandem with formula in parallel is comprehensive, it has given full play to tandem and the advantage of formula in parallel, the parts such as engine, generator, electric motor can be made more to optimize coupling, thus structurally ensure that and system still can be made under more complicated operating mode to work under the optimal condition. But its structure is very complicated, its match control is also very difficult simultaneously.
In sum, current hybrid power system is not well positioned to meet the demand of advanced environment-friendly energy-saving automobile, urgently need the hybrid power system technology of development of new, effectively overcome efficiency low, the exhaust emission high problem of engine when low speed and off-design point, it is achieved the green high-efficient of automobile and energy-conserving and environment-protective.
