Abstract
A system and method for determining vehicle mass relative to a previous mass of the same vehicle utilizes a closed-loop control system to bring the vehicle to a controlled deceleration upon initiation of the procedure. The relative mass of the vehicle is determined by sensing the applied braking pressures at each of the vehicle axles and processing that information to generate the total braking force being applied to the wheels of the vehicle. Since a greater mass requires a greater braking force to achieve the same deceleration, the necessary braking force is indicative of the relative vehicle mass. An appropriate braking mode such as work balance, proportioning, or ABS, can then be determined based on the relative vehicle mass to better control subsequent braking maneuvers.
