N2 - The objective of the article is to develop an analytical model to investigate the dynamic behaviour of an automotive powertrain during gearshifts. First, an integral model is proposed by incorporating lumped-mass component models, and its compatibility with previous control-oriented models is experimentally validated. Second, gearshifts that induce dynamic behaviour including clonk, contact loss and clutch stick-slip are numerically simulated. The mechanism and impact source of the dynamic behaviour and also the coupling characteristic between different dynamic behaviours are studied. The dynamic characteristics of the behaviour are studied by obtaining the wavelet transform of the output torque. Finally, the impacts of the system parameters on the dynamic behaviour are examined by using the proposed model.
