ABSTRACT:
A system is disclosed for determining the spacing between axles of a vehicle which may be in motion, on the basis of weight alone. A weighbridge is provided with a first load cell spaced from a second load cell along the length of the weigh bridge by a distance L, with each load cell being responsive to the load on its respective location on the weighbridge. After a first axle is on the weighbridge, the weight on the first load cell and the weight on the second load cell are periodically sampled. The average stored weight M1 of the first axle is determined at the time that a second axle is about to enter the weighbridge. The instantaneous weight W2 on the second load cell is measured at the time that the second axle is about to enter the weighbridge. The distance X.sub.1 between the first axle and the second axle is determined by calculating
