ABSTRACT:
A system and method of sensing a load on a vehicle that includes a plurality of wheel-engaging members is disclosed. The vehicle body is supported on the plurality of wheel-engaging members and receives a cargo having a cargo weight. The method includes providing a non-fluid spring having an unloaded length and a spring rate, the non-fluid springs are supported between the vehicle body and one of the wheel-engaging members and being deflected to a loaded length under the cargo weight of the cargo. The method continues with determining the loaded length of the non-fluid springs. The method also includes determining an approximate value of the cargo weight based at least partially upon the spring rate and the loaded length of the non-fluid spring.
