A study on tyre force distribution controls for full drive-by-wire electric vehicle

Feed-forward types of tyre force distribution controls with some norms for motion controls of a full drive-by-wire electric vehicle are presented. One of the norms for the distribution control introduced is minimising tyre workload and another one is minimising tyre dissipation energy due to tyre slip during vehicle motion. The effects of the distribution controls are substantiated using an experimental vehicle on a proving ground. Especially the effects of the tyre force distribution norms on improving vehicle stability and on reducing the tyre energy dissipation caused by tyre slip are investigated.
