Abstract

The present invention discloses one kind of double engine automobile power system, which includes one main engine, one main clutch, one main speed variator, one differential gear and wheels connected successively to constitute one main power system, as well as one auxiliary engine and one auxiliary speed variator connected to constitute one auxiliary power system. The auxiliary power system has an output shaft connected through one gear train to the output shaft of the main engine. The present invention can save fuel oil, reduce emission and lower cost effectively. The present invention also discloses the control method of the double engine automobile power system.

Description

technical field [0001] The invention relates to an automobile power system, in particular to an automobile power system with two engines, and to a control method for the power system. Background technique [0002] Energy and the environment have become two decisive factors affecting the future development of the automobile industry. Improving engine efficiency and developing new energy vehicles are not only important ways to solve energy constraints, but also the commanding heights to enhance a country's competitiveness. At present, the choice of technology has formed a trend of diversification. [0003] It can be seen from the engine power characteristics that in order to make the fuel work efficiency of the engine the highest, it is necessary to make the engine work at the maximum load rate state. However, in a vehicle, the matching of the engine power required by the vehicle is uncertain; therefore, it is unrealistic to make the engine work at full load. Therefore, for...
