Abstract: 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 t… Show more

“…where g = 450, which is approximately estimated by equation 7based on experimental data. [35][36][37] In this regard, it is seen that Conv. increases the clutch friction torque at a constant rate during mode shift.…”

“…Typical value of rolling resistance coefficient δ is set to 0.005 m. The output torque from engine T e is set to constant value 323.47 N•m, so that the impact of engine forced vibration on clutch dynamics is excluded [40]. This value for the engine torque is identified through a number of iterations as the point at which the output torque is high enough to initiate stick-slip in the clutch.…”

“…In urban driving, drivers tend to accelerate and brake vehicles frequently. He et al 1 developed an analytical model to investigate the dynamic characteristics of powertrain systems in the process of variable-speed vehicles; it has some guidance for using transmission and differential vehicle drive system development. However, the electric vehicles with four-wheel independently driven in-wheel motors cancel the mechanical parts such as the transmission and the differential gears, and the four-wheel driving torque and braking torque can be controlled independently.…”
