SYSTEM AND METHOD FOR VEHICLE AXLE LOAD MEASUREMENT WITH HYSTERESIS COMPENSATION AND ACCELERATION FILTER

摘要

Vehicle on-board measurement of axle (46) load and gross combined vehicle (24) weight is improved for an air bladder (44) suspended vehicle (24) by allowing for suspension hysteresis. Suspension hysteresis results in at least two distinct air pressures being possible in an air bladder for a single load. The system also reduces the disruptive effect of vehicle acceleration and deceleration on load determination. Vehicle (24) drive train management is enhanced using the load information to effect transmission (72) gear selection.
