Research on vehicle control strategy for electric variable transmission in HEV

This paper focused on the vehicle control strategy for electric variable transmission in hybrid electric vehicle. The operation modes of hybrid electric vehicle based on electric variable transmission were analyzed, and the vehicle control strategy based on the logic thresholds was proposed, according to the power requirement, current vehicle speed, and SOC of battery. Then, the simulation model of hybrid electric vehicle based on electric variable transmission was built, and the simulation results demonstrate the feasibility of the proposed strategy.
