Abstract
An electric machine control system for a vehicle having an electric machine arranged to be selectively couplable to provide torque to a wheel of an axle. An input receives a fault-derived coupling state request signal and a further coupling state request signal. Each coupling state request signal is indicative of a request for a coupling state of the electric machine to the wheel of the axle. A processor determines the coupling state of the electric machine to the wheel of the axle in dependence on the fault-derived coupling state request signal and the further coupling state request signal. The processor determines the coupling state of the electric machine in precedence on the fault-derived coupling state request signal over the further coupling state request signal. A coupling signal indicative of the determined coupling state is output to control coupling of the electric machine to the wheel of the axle.
