1. A control unit for determining a value indicative of a load bearing capability of a ground segment supporting a vehicle, the control unit configured to:
issue a control signal to the vehicle to thereby impart a motion change to the vehicle;
receive response information from the vehicle indicative of the vehicle's response to the imparted motion change;
based on the response information, determine a vertical position change of at least one wheel of the vehicle, and
based on the determined vertical position change and the imparted motion change, determine the value indicative of the load bearing capability of the ground segment.
