Single wheel hub motor failures and their impact on vehicle and driver behaviour
(English)Manuscript (preprint) (Other academic)
This research work studies the impact of single wheel hub motor failures on the dynamic behaviour of electric vehicles and the corresponding driver reactions. An experimental study in a moving-base driving simulator is conducted to analyse the inuence of single wheel hub motor failures for motorway speeds. Driver reaction times are derived from the measured data and discussed in their experimental context. The failure is rated objectively on the dynamic behaviour of the vehicle and compared to the subjective evaluation. Findings indicate that critical trac situations impairing trac safety can occur for motorway speeds. Clear counteractions by the drivers had to be taken.
