STUDY ON A MILD HEV’S PERFORMANCE SIMULATION AND PROPULSION SYSTEM PARAMETER MATCHING

Abstract

Abstract: A powertrain constructions and control strategy of a parallel hybrid electric vehicle (HEV) adopting the technology of integrated starter/generator (ISG) are introduced. The dynamic model of describing the standing up acceleration process of the HEV equipped with the dual model continuously variable transmission system is build up, and simulation is given .The influence of the motor peak power, peak torque and engine startup speed on the HEV’s performance and powertrain torque response is analyzed, and a matching design method for the HEV propulsion system is proposed, which provided the theo-retical foundation for mild HEV’s conceptual design.

Key words: CVT, Hybrid electric vehicle, Parameter matching, Propulsion system, Simulation
