ABSTRACT
 
The content is designed general design of oil-electric hybrid microbus．Mainly design of a low oil consumption, low emission of energy conservation and environmental protection miniature passenger cars. Faced with a mini bus on the market situation, hybrid miniature buses to ascend the strategic design, mini bus the competition ability of the enterprise has a very important significance; Also to the increasingly serious environmental problem made improvement.
This design for hybrid cars power system structure and working principle of a study, work the vehicle driving system and the overall coordination body chassis and according to its structure and the relationship between the principle, determine the oil - electric hybrid mini bus the general structure and the overall plan and make hybrid system of drive systems, auxiliary power system and the part such as design and calculation of the battery and the choice; Complete driving system component selection and matching parameters; Research the braking energy and recycling. This paper expounded from whole hybrid car on the working principle and control strategy. Based on the original car completed a hybrid car dynamic system design. The dynamic performance and efficiency are checked, and compared with the original mini bus, validation hybrid each parameter selection of rationality and the hybrid's superiority.
