• Changes in the structure and operating conditions of hybrid vehicles have caused new vibration and noise problems. In order to save energy and reduce emission, the hybrid vehicle will start or stop the engine selectively under different road conditions. The annoying vibration of vehicles during engine start and stop process is not expected by the drivers, whose influences for ride comfort can not be ignored. This paper studies the excitation source of the engine, analyzes the pumping resistance, inertial resistance and combustion torque of the engine, and establishes an exhaustive engine model based on the analysis results in ADAMS. Finally, co-simulation results show that using the coordinated torque control of the large and small motors, the vibration of the whole vehicle in the mode-switch between engine start and stop is reduced significantly.
