The following conclusions can be drawn from the research presented in this paper: Depending on the engaged gear ratios of the front and rear drivetrains, the frequency response of the physical parameters relevant to HEV drivability can be characterised by either one or two peaks, one for each axle, in the range 1-10 Hz. In opposition to the typical second order response of FWD internal combustion engine driven vehicles, the HEV tip-in response shows a more complex time history due to the combination of the first natural frequencies of each drivetrain. In order to achieve a good approximation of HEV drivability response, it is necessary to consider the linear torsion dynamics of half-shafts and tyres. More complex models can be useful for component analysis and design but do not significantly affect the overall response. The front-to-rear torque bias ratio exerts a very relevant effect on the low frequency drivability of HEVs.
