1. A control system for a vehicle, the control system comprising one or more controllers, wherein the control system is configured to:
receive a torque request for an internal combustion engine configured to mechanically couple to a first axle of the vehicle;
determine a shortfall relative to the torque request, dependent on torque providable by the engine; and
provide an output to control an electric machine to provide a compensation torque configured to compensate for the shortfall,
wherein the electric machine is mechanically coupled to a second axle of the vehicle,
wherein a further electric machine is configured to mechanically couple to the first axle of the vehicle, and
wherein the control system is configured to control an extent to which at least one of the electric machine and the further electric machine provides at least part of the compensation torque, based on whether torque from the other of the electric machine and the further electric machine is limited by a lash crossing protection function.
