Claim 12:
13. A control unit for determining a parameter indicative of a road capability of a road segment supporting a vehicle, said vehicle comprising a vehicle frame, plurality of ground engaging members and a suspension system connecting the plurality of ground engaging members to said vehicle frame, said control unit being adapted to:
for each ground engaging member in a sub-set of said plurality of ground engaging members, set a contact force between said ground engaging member and said road segment;
determine a target global load vector to be imparted to said vehicle, said target global load vector comprising at least a vertical load and an inclining moment,
determine contact forces for the ground engaging members of said plurality of ground engaging members which are not in said sub-set such that the contact forces for said plurality of ground engaging members together result in a resulting global load vector, a difference measure between said resulting global load vector and said target global load vector being equal to or lower than a predetermined difference measure threshold,
issue information to said suspension system to impart said contact force to each ground engaging member of said plurality of ground engaging members,
for at least one ground engaging member in said sub-set, determine a parameter indicative of the road capability of the road segment associated with the ground engaging member.
