1. A vehicle motion management system for a vehicle, the vehicle motion management system being connectable to a motion support system coupled with at least one actuator configured to apply a torque to at least one wheel of the vehicle, for communication of control signals between the vehicle motion management system and the motion support system, wherein the vehicle motion management system is configured to:
determine a desired torque for operating the vehicle at a current vehicle operating condition;
determine an offset wheel speed parameter;
obtain a signal indicative of a wheel speed for the vehicle;
determine a wheel slip limit for the at least one wheel of the vehicle based on the offset wheel speed parameter when the wheel speed is less than a threshold vehicle speed limit;
determine, based at least on the wheel slip limit and the desired torque, a wheel speed limit for the at least one wheel of the vehicle, wherein the wheel speed limit comprises an upper wheel speed limit and a lower wheel speed limit;
transmit a control signal indicative of the desired torque to the motion support system for use in controlling the at least one actuator to apply the torque to the at least one wheel of the vehicle;
transmit only the upper wheel speed limit to the motion support system when the desired torque is greater than zero;
transmit only the lower wheel speed limit to the motion support system when the desired torque is less than zero; and
control the actuator to generate the desired torque on the at least one wheel.
