Abstract
Aspects of the present invention relate to a method and to a control system for controlling an electric traction motor of a vehicle, the control system comprising one or more controllers, wherein the control system is configured to: limit a rate of change of torque requested from the electric traction motor for changing speed towards a speed target, in dependence on a lash crossing protection rate limiter; and upon removal of the limit prior to the speed reaching the speed target, inhibit initial increase of a torque requested from the electric traction motor for changing speed towards the speed target.
