Abstract

The invention relates to a control unit and method for a vehicle having a plurality of independently-driven wheels. A control unit for a vehicle having a plurality of independently-driven wheels, the control unit comprising an input unit for receiving a steering command, a speed command and outputs from acceleration sensing units being locatable at respective wheels of the vehicle; and a processor in communication with the input unit and being operable to calculate for each wheel a desired wheel rate including (i) a main component based on the speed command; and (ii) a manoeuvre response component based on the steering command and on accelerations induced by the steering command and/or terrain conditions.
