Abstract: In the field of off-highway trucks, overloading and disproportionate load placement lead to undesirable vehicle stresses. The present invention pertains to an apparatus for displaying the distribution of the load, in an off-highway truck, to both the truck operator and the loader operator. The information is conveyed to the operators using displays having varying color ranges generally indicative of the load in portions of the dump body of the truck. Using this tool the truck operator attains optimum positioning of the truck prior to and during the loading cycle, while the loader operator directs loads to portions of the dump body having lower displayed loads.

Abstract: An apparatus for communicating a vehicle parameter to a location remote and apart from where the vehicle parameter is measured is disclosed. The apparatus comprises a sensor responsive to the parameter being measured, with the sensor producing an output analog signal proportional to the vehicle parameter being measured. The output analog signal is subsequently converted into a digital signal whereby the vehicle parameter being measured is represented by an N-bit digital code. The N-bit digital code is subsequently transmitted to a location remote and apart from where the vehicle parameter is being measured, and is converted into a continuous analog signal representing the vehicle parameter being measured. The analog signal is subsequently displayed in a viewer usable form. The disclosed apparatus also includes a calibration means which simulates the sensor output analog signal and is switchable therewith to enable end-to-end calibration of the disclosed apparatus.
