Study on Engine Idling Torque and Speed Ripple Cancellation of HEV

Abstract:

According to the character of the torque and speed ripple of the engine idling analysed from its Fourier transformed, use motor torque to compensates the primary and second harmonics of Fourier transform of the output net torque during engine idle in HEV. The simulation results show that the engine torque ripple and speed ripple decrease greatly, so the system smoothness and economic efficiency were achieved.
