Method for displaying load distribution by monitoring a work vehicle suspension
First Claim
1. An apparatus for displaying the distribution of a payload loaded onto a work vehicle by a separate loading vehicle, said work vehicle having a plurality of hydraulic struts in supporting relation to the payload comprising:
- means for sensing the internal pressure of preselected struts and delivering a plurality of first signals each having a value responsive to the internal pressure of one of said respective struts;
means for modifying each of said first signals, and delivering modified signals in response to said modification, each modified signal being indicative of the payload supported by one of said respective struts;
visual display means on the loading vehicle for receiving said modified signals, and displaying respective visual signals in response to the magnitude of said modified signals.

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.

15. A system for displaying the distribution of a payload on a work vehicle, said work vehicle having a plurality of hydraulic struts in supporting relation to the payload, comprising:
-
means for sensing the internal pressure of preselected struts and delivering a plurality of first signals each having a value responsive to the internal pressure of one of said respective struts; a microprocessor for receiving and modifying each of said first signals, and for delivering modified signals in response to said modification, each modified signal being indicative of portion of the payload supported by one of said respective struts; and a visual display including four display elements for receiving said modified signals and displaying respective visual signals in response to the magnitude of said modified signals, each of the four elements having four sections and being representative of a corner of said work vehicle, each of the four sections being representative of a load range on said respective strut. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)
