As a car enthusiast, I paid great attention to the development of domestic cars dynamic, especially in recent years, world fuel shortage, price rises quickly, environmental protection, high calls the situation, the more inspired us explore relevant issues of interest. Automotive innovation is the key power systems. Power system of the most important traits in driving mode .Let us first examine the drive mode of evolutionary history (Hantula 2009).
In 1801, Richard Trevithick creates the earliest steam cars. In the initial period of development steam cars, their designs are simple, is a steam engine mount chassis and wheel. In order to reach a certain output power, there must be a large boiler, In order to attain the certain trip, and to prepare sufficient water and coal; Body weight, will demand have a pair of strong chassis and strong wheels. So car more bulky manipulation has become increasingly difficult (Hantula 2009).
In 1885, from Germany engineer Karl enterprise Benz developed into a truck carrying 0.85 horsepower engine tricycle. This is the world's first car gasoline engine car. Meanwhile, Germany Gottlieb Daimler another engineer also developed a car with 1.1 horsepower gasoline engine powered four-wheel cars. This is also a car development history cross time change (Yost 2006).
Current global warming, auto crude oil consumption take up almost half the CO2 emissions of greenhouse gas emissions take up almost 2 into. Automobile industry is facing a great historic transformation, the electric car, the fuel automobile replace eco-car already belonged to the development of new energy inevitable, car, and to make the power system of new energy-oriented, promote the traditional automobile industry to the strategic transformation in the world has been formed widely Shared understanding. In this situation, the United States, Japan, Europe and other developed countries and regions, new energy to coincide the ground as a representative of the low carbon industry as a national strategy choice, all hope that through new energy industry and traditional automobile industry, automobile industry of the combination of cracked energy environment condition, to cultivate the new strategic industry, promoting industrial core competitiveness, low-carbon economy development, realize a new round of economic growth. In solar energy, electricity alternatives such as energy to really get into practical stage before, hybrid cars because of its low oil consumption, low emission advantage more and more attention (Miller 2004).
The current with the widespread use of fuel engine car exists many problems, statistics show that in occupied more than 80% of the road conditions, a car ordinary car only using a dynamic potential 40%, in urban areas will fall to 25%, more serious is the emissions environmental pollution. During the 1990s, the various countries to improve environmental calls for increased, various electric car stand out. Although it is widely believed that the future is electric cars, but at present the battery technology issues hampering electric vehicle applications. Because the battery energy density compared with gasoline behind hundredfold, far from reaching people demanded by the numerical, experts estimate in 10 years within the electric vehicle is cannot replace fuel engine car. From the current worldwide the whole situation perspective, Japan is electric vehicle technology fastest developing speed in one of the few countries, especially in the development of hybrid cars, Japan standing in the leading position. At present, the world can batch production and marketing of Hybrid cars enterprise, only Japan's Toyota and Honda two auto companies (Hasegawa & Kimm 2008).
In December 1997, Toyota first in Japan launched on the market in the world in the first paragraph of batch production of PRIUS hybrid cars. HEV (Hybrid - Electric Vehicle) - Hybrid device. Hybrid cars is refers to use petrol and electric drive two drive mode, the advantage lies in vehicles start stops, only by the generators, do not reach a certain speed, the engine will not work, therefore, can make the engine has remained at best working condition, good dynamic performance, its emissions are low, and electrical energy sources are engine, only refuel can charge. Hybrid cars with oil, electricity engine complementary work mode, have fuel-efficient and energy-saving advantage. Meanwhile, hybrid systems under the same conditions relative to gasoline vehicles and engages the speaking, car exhaust emission, thus reduce to less air pollution. Therefore, hybrid cars have environmental protection; low pollution advantages (Hantula 2009).
