摘要： In one aspect of the present invention, a method for determining and displaying a correlated position of a truck as it is being loaded by an earth moving machine is provided. The method includes the steps of receiving a loading event signal and then determining the correlated position of the truck in response to the loading event signal. The correlated position of the truck is then displayed relative to the land size.In an alternative embodiment, a method for determining and displaying productivity information regarding material excavated by an earth moving machine and loaded into a truck is provided. The method includes the steps of determining the bucket load material type of the material loaded in the bucket. Productivity information is then displayed at a remote location in response to the bucket load material type.

摘要： The present invention provides a site database structure for storing data for access by an application program being executed on a control system on a work machine. The work machine operates at a work site. The data representing a parameter of the work site. A data structure is stored in the memory. The data structure includes information resident in a database used by the application program. A plurality of data objects are associated with the data structure. Each data object represents a defined section of the work site and is represented by a set of predefined coordinates. At least one layer object is associated with each data object. Each layer object has a predefined number of cell objects. Each cell object has an associated value of the parameter.

摘要： The present invention provides a method for updating a site database. The site database models the elevation of a work site using a Triangular Irregular Network (TIN). The TIN is composed of a plurality of points. Each point has associated known X and Y coordinates and a known elevation and is associated with a set of other points in the network to form triangles. The work site is modified by a work machine. The method includes the steps of receiving a new set of points. The new set of points includes at least first and second points. The first and second points have associated X, Y, and Z coordinates. The method also includes the steps of comparing the new set of points with a previous set of points and updating the triangular irregular network with the new set of points if a minimum distance has been traversed by the work machine.

摘要： An electrohydraulic control device for a drive train of a machine is disclosed. The drive train includes an engine, a transmission, and a torque converter having a rotating housing. The torque converter is drivingly connected between the engine and the transmission. The torque converter also includes an impeller element. An impeller clutch connects the impeller element to the rotating housing. An impeller clutch electrohydraulic valve produces fluid flow to the impeller clutch to controllably engage and disengage the impeller clutch. A torque converter speed sensor senses the output speed of the torque converter and responsively produces a torque converter speed signal. A electronic device receives the measured torque converter speed signal, determines a desired torque convertor speed signal, produces an error speed signal in response to a difference between the measured and desired torque converter speed signals, and controllably actuates the electrohydraulic valve to cause the speed error signal to approach zero.
