Patent ID: 8019530

Claim:
A method for judging the distribution of a load supported by wheels mounted on a vehicle based on the rotational speeds of the wheels, wherein the load includes variable loading carried by the vehicle, the method comprising the steps of: a) detecting the rotational speeds of the wheels; b) detecting whether a brake, or brakes, on the vehicle are being operated or not being operated; c) calculating a first value resulting from a comparison of the rotational speeds of two of the wheels with respect to the rotational speeds of others of the wheels when the brake, or brakes, are being operated; d) using a computer for comparing the first value with a stored second value resulting from a comparison of the rotational speeds of the two wheels with respect to the rotational speeds of others of the wheels when (1) the brake, or brakes, are being operated and (2) the distribution of the load is in a predetermined load distribution state; and e) judging the distribution of the load from the comparison performed in step d.
