System and method for determining relative vehicle mass

摘要: A system and method for determining vehicle mass relative to a previous of the same (10) utilizes closed-loop control (100-156) bring controlled deceleration upon initiation procedure. The is determined by sensing applied braking pressures (60,62,88) at each axles (20-28) processing that information generate total force being wheels vehicle. Since greater requires achieve deceleration, necessary indicative mass. An appropriate mode such as work balance, proportioning, or ABS, can then be based on (142) better subsequent maneuvers.
