Abstract
Official abstract text for this publication.
A position identification system for use with a mobile machine at a worksite is disclosed. The system may include an integration module configured to integrate information from at least one motion sensor and at least one GPS receiver to generate a location signal indicative of an actual location of the mobile machine. A controller may be provided in communication with the at least one motion sensor, the at least one GPS receiver, and the integration module, the controller being configured to determine the reliability of information received from the at least one motion sensor, the at least one GPS receiver, and the integration module, and following a period of time from when received information is first determined to be unreliable, switching from determining the position of the mobile machine using information determined to be unreliable to determining the position of the mobile machine using dead reckoning from a last known good position of the mobile machine, a determined wheel speed of the mobile machine, and a steering command being provided to the mobile machine.
First claim
Opening claim text (preview).
What is claimed is: 1. A system for determining the position of a mobile machine, the system comprising: at least one motion sensor configured for detecting one or more of changes in position, velocity, acceleration, heading, wheel speed, rotation, steering angle, or orientation of the mobile machine; at least one global positioning system (GPS) receiver in addition to said at least one motion sensor, said at least one GPS receiver configured to generate a first location signal…
