Claim 9:
10. An electric machine control system for a vehicle, the electric-machine control system, comprising:
one or more controllers, wherein the vehicle comprises an electric machine arranged to be selectively coupleable to provide torque to at least one wheel of an axle of the vehicle, the control system comprising:
an input arranged to receive a speed signal indicative of a speed of the vehicle and a status signal indicative of a status of a coupling of the electric machine to the at least one wheel of the axle of the vehicle;
an output arranged to output a coupling signal to control coupling of the electric machine to the at least one wheel of the axle; and
a processor arranged to determine a coupling state of the electric machine to the at least one wheel of the axle and to control the output to output a coupling signal indicative of the determined coupling state, wherein the processor is arranged, in dependence on the status signal being indicative of a failure to change the coupling state of the electric machine to the at least one wheel of the axle in dependence on a change in the determined coupling state, to control the output to output the coupling signal indicative of a retry of the change in the coupling state in dependence on the speed signal up to a predetermined maximum number of times.
