Forward simulation model precision study for hybrid electric vehicle

Co-simulation model of forward hybrid electric vehicle (HEV) is established in this paper. And according to three aspects: traditional vehicle model (mechanism system model), electric system model and vehicle control strategy, the precision of the co-simulation model has been analyzed and checked by the revolving drum test bench of the First Automobile Workshop (FAW). The forward simulation model database is founded to perfect the forward model platform of HEV, which will be a developing foundation for the new vehicle design.
