Abstract: A system and method for analyzing and providing exception-based reports for machine data. The machine data is relayed to a remote system for automated analysis based on tests and parameters defined by an owner. If any exceptions are detected in the data based on the operator-defined input, output is generated. The output may take the form of exception-based printed or electronic reports, or the exception information may be relayed to a hand held device, preferably maintained by service personnel at the work site.

Abstract: The present invention provides a method and apparatus for automatically limiting the ground speed of a work machine. The work machine is adapted to move about the ground of a work site. An electronic site map having at least one speed restriction is maintained at a site office. The work machine monitors its position using an onboard GPS system and compares its actual speed and position to the site map. If the work machine exceeds the speed restriction, the work machine receives a signal and reduces speed.

Abstract: The present invention provides a method and apparatus to automatically control the speed of a work machine 10 based on ton-miles-per-hour limit of at least one of a plurality of tires 12. A vehicle information system 28 having a processor 32 and a database 34 monitors an actual ton-miles-per-hour calculation of the plurality of tires 12. The vehicle information system 28 functions in combination with an electronic control module 66 of the machine 10 to trigger an automatic speed reduction should the actual ton-miles-per-hour rating exceed a predetermined limit. The speed reduction may be affected by at least one of reducing a throttle setting, changing a transmission gear and automatic application of the machine brakes.

Abstract: A method and apparatus is provided for calibrating a payload monitor of a work machine. Altering the load carrying body of a work machine can adversely impact the accuracy of a payload monitor. The present invention provides a calibrating technique using an alternate coefficient that is programmed into the payload monitor. The alternate coefficient is then used by the payload monitor.

Abstract: This invention relates to a method and apparatus for determining road conditions base on monitoring a plurality of parameters of a machine system. The machine system includes a payload system, an engine control system, a transmission system and an accelerometer. A control module monitors the machine systems and estimates the torque output of a drivetrain. By analyzing data from the systems the control module can determine if the machine is being operated on road that is in need of repair and dispatch equipment to repair the road.

Abstract: An electronic control is provided for controlling the drive speed of a supplemental drive relative to an engine driven main drive of a vehicle. A fluid pump driven by the engine provides pressurized fluid flow. The supplemental drive is driven by the pressurized fluid. A main drive sensor senses the speed of the main drive and responsively produces a main drive speed signal. A command knob is provided for selecting a desired speed relationship between the main and supplemental drives. A knob sensor senses the position of the command knob and responsively produces a modifier signal. A modifier circuit receives the main drive speed and modifier signals and responsively produces a modified main drive speed signal. A supplemental drive sensor senses the speed of the supplemental drive and responsively produces a supplemental drive speed signal. A processor produces an error signal responsive to a difference between received modified main and supplemental drive speed signals.

Abstract: A payload monitoring system of a work vehicle includes a software controlled method of predicting when one additional bucketload of material will properly fill the vehicle to its rated capacity. The system calculates the actual magnitude of each bucketload of material and adds that value to the present payload to predict the future payload resulting from an additional bucketload of material. When the predicted future payload encompasses the rated capacity, the system signals the operators of both the work vehicle and the loading vehicle that one additional pass will complete the loading process.

Abstract: Anti-spin control systems are useful, for example, in industrial off-road vehicles. It is desirable that such systems exhibit rapid response to adverse working conditions, and be capable of quickly applying braking forces to whichever driven wheel is rotating at a higher velocity at a given time. The instant invention includes an electrical circuit for producing first and second brake control signals having values responsive to a working condition wherein one of the vehicle wheels loses traction and rotates more rapidly than the other vehicle wheel. A first controllable valve receives the first brake control signal and responsively controllably engages a brake mechanism associated with the faster rotating wheel, while a second controllable valve receives the second brake control signal and responsively controllably moves a brake mechanism associated with the slower rotating wheel from a brake released position to a brake pre-engaged position.
