Vehicle load measuring systems
First Claim
1. A system for measuring loads in a vehicle comprising at least one sensing element selected from any of strain and displacement sensing elements and a respective electronic interface disposed locally to each said sensing element, said sensing element and said respective local electronic interface being adapted to be linked to a main electronic control unit disposed in a vehicle with which the load measuring system is associated at a location remote from said local interface, the load measuring system further comprising internal micro-controller means within said local interface which is adapted to receive signals from said main electronic control unit to switch elements of the load measuring system into both zero setting and calibration modes, said micro-controller in said local electronic interface having electrically alterable, non-volatile memory which is adapted to store zero setting and calibration data for subsequent use in a normal operating, load measurement mode of the system.

Abstract
A system for measuring loads in a vehicle comprising strain and/or displacement sensing elements and a local electronic interface which are adapted to be linked to a main electronic unit in a vehicle with which the load measuring system is associated. The load measuring system comprises an internal micro-controller within the interface which is adapted to receive signals from the main electronic unit to switch elements of the load measuring system into both zero setting and calibration modes. The micro-controller has electrically alterable, non-volatile memory which is adapted to store zero setting and calibration data for subsequent use in a normal operating, load measurement mode of the system.
