Navigational off- line and off-heading indication system and method

摘要

The present invention is a system and method that provides off-line and off-heading correction information in a convenient format that is easy for an operator to comprehend. A dual mode indication system of the present invention provides two different types of navigation information in a single device presentation configuration that is efficient and effective. The dual mode indication system presents information in a manner that is intuitive with minimal sensory resource commitment. In one embodiment of the present invention the dual mode indication system includes a light emitting diode (LED) light bar that provides off line information by selectively illuminating LEDs in a pattern that corresponds to the relative position of a vehicle to a desired line of travel (e.g., along an agricultural planting row). In one embodiment of the present invention the dual mode indication system includes an analog dial that provides an indication of an appropriate heading for the vehicle to make adjustments and stay on heading and on line. In one exemplary implementation of the present invention the analog dial rotates to point in an appropriate heading. Providing the off line and off heading in these simplified and effective formats permits assist a vehicle operator keep a vehicle on a desired line and moving in a correct direction with minimal operator effort expended observing, interpreting and analyzing the navigation information.
