Abstract The paper analyzes the force distribution of hybrid electric vehicles based on electric variable transmission. Firstly, the simulation model of hybrid electric vehicles is built with the ideology of reverse simulating, providing a platform for the study of force distribution strategy. Then, according to the vehicle requirement analysis, the transmission ratio of electric variable transmission is respectively designed based on ON/OFF control strategy and power following strategy, and the output torque of engine and electric variable transmission is assigned based on fuzzy logic control strategy. Meanwhile, an instantaneous optimization strategy of output power distribution is proposed, which is realizes by forward dynamic programming optimization algorithm. At last, this paper carried on the contrast analysis of engine and electric variable transmission’s working conditions, fuel consumption and emission performance under the different force distribution strategy.

Key words： Hybrid electric vehicle electric variable transmission force distribution instantaneous optimization
