Control Strategy of Stability Optimization for HEV Powertrain

In recent years, the deterioration of energy and environmental issues has accelerated the growth of electric and hybrid vehicles. Because of their versatile driving mode, long range, and low emissions, hybrid electric vehicles (HEVs) are becoming increasingly popular. However, current research on the torsional vibration of HEV powertrains focuses primarily on the effect of engine excitation, as well as natural frequency and modal analysis. The aim of this chapter is to improve the control strategy of a HEV powertrain while taking torsional stability into account in three common driving modes.
