Abstract: Hybrid electric vehicles cannot only save energy and reduce emissions, but also solve the range anxiety problem of electric vehicles, therefore becoming an important breakthrough direction of low-carbon vehicles. The electromechanical coupling system is an important part of hybrid electric vehicles, including the single-motor hybrid system, the series-parallel hybrid system, the power-split hybrid system, and other different routes. First, three basic configurations are established for the three technical routes respectively. Then, the optimal configuration of each basic configuration is obtained through optimisation analysis. Finally, the series-parallel technical routes are confirmed by comprehensive comparison, and the configuration design is carried out. This paper systematically describes the whole process of scheme design, which can provide reference for other automobile companies that develop electromechanical coupling systems for hybrid electric vehicles.
