Abstract：This paper gives a brief introduction to the development status and working principle of parallel hybrid electric vehicles at home and abroad. Secondly, the advantages of parallel hybrid vehicles are introduced.This article gives a brief introduction to the working principle and advantages of parallel hybrid vehicles. Compared with series hybrid vehicles, parallel power vehicles, motor power and the capacity of their associated battery packs can be significantly reduced, resulting in a significant reduction in the equipment quality of the vehicle, and the driving range can be compared with the traditional The fuel car is comparable to the first car of the hybrid car, and it is also the most competitive vehicle in the development of the traditional fuel car to the pure electric car. Secondly, the transmission ratio of the transmission of the parallel hybrid electric car is an important factor affecting its performance. Especially in the urban working conditions, this topic takes a hybrid electric car as an example to typical urban conditions. In order to study the conditions, the orthogonal experimental design method was used, and the electric vehicle simulation software ADVISOR2002 was used as the simulation platform to optimize the gear ratio of the transmission, so that the vehicle can meet the dynamic requirements when operating in typical urban conditions. Has good economy and emissions.

Key words: parallel hybrid vehicle; power and transmission system design; orthogonal test; simulation analysis
