A control system 100 for controlling at least one electric traction motor (312, 314) of a torque limited vehicle (200) in which the at least one electric traction motor has a torque limit. The control system is configured to receive an indication 145 of a torque demand; output a torque request signal 155 for the at least one electric machine. In dependence on the torque demand determine an expected acceleration of the vehicle receive an indication 146 of the actual acceleration of the vehicle. Compare the expected acceleration to the actual acceleration; determine if the expected acceleration exceeds the actual acceleration by a threshold amount. If so, output a torque limit override signal 156. The torque limit signal may define a further torque limit. Brake demand and gradient may be used as a limitation condition.
