6. A guidance system for an agricultural vehicle, the guidance system comprising:
a satellite system receiver for receiving signals from a plurality of navigation satellites and for determining locations of the agricultural vehicle as a function of the signals;
a display responsive to the satellite system receiver for displaying a representation of the vehicle's location on a cartographic map; and
a control device configured for:
receiving location data from the satellite system receiver;
comparing the location data to cartographic data for a desired path of the vehicle;
producing steering commands to be delivered to a steering actuator;
receiving an indication of an operating state of the vehicle; and
controlling a viewing mode of the display according to the operating state, wherein the operating state is a position of the vehicle relative to a field boundary, the viewing mode is a field of view of the display, and the control device is configured to switch the display to a perspective view whenever the vehicle is greater than a threshold distance from the boundary and to switch the display to a plan view whenever the vehicle is less then the threshold distance from the boundary.
7. The guidance system as set forth in claim 6 , wherein the operating state is a position of an implement coupled with the vehicle, the viewing mode is a field of view of the display, and the control device is configured to switch the display to a perspective view whenever the implement is raised and to switch the display to a plan view whenever the implement is lowered.
8. The guidance system as set forth in claim 6 , wherein the operating state is a status of a spray coupled with the vehicle, the viewing mode is a field of view of the display, and the control device is configured to switch the display to a perspective view whenever the sprayer is disabled and to switch the display to a plan view whenever the sprayer is operated.
9. The guidance system as set forth in claim 6 , wherein the operating state is a status of a vehicle guidance system, the viewing mode is a field of view of the display, and the control device is configured to switch the display to a perspective view whenever the vehicle guidance system is enabled and to switch the display to a plan view whenever the vehicle guidance system is disabled.
10. The guidance system as set forth in claim 6 , wherein the operating state is a location of the vehicle relative to a field boundary, the viewing mode is a field of view of the display and a magnification level of the display, and the control device is configured to switch the display to a perspective view and a first magnification level whenever the vehicle is greater than a threshold distance from the boundary and to switch the display to a top view and to a second magnification level greater than the first magnification level whenever the vehicle is less then the threshold distance from the boundary.
11. A guidance system for an agricultural vehicle, the guidance system comprising:
a satellite system receiver for receiving signals from a plurality of navigation satellites and for determining locations of the agricultural vehicle as a function of the signals;
a display responsive to the satellite system receiver for displaying a representation of the vehicle's location on a cartographic map, wherein the display can show at least two different perspective views; and
a control device configured for:
receiving location data from the satellite system receiver;
comparing the location data to cartographic data for a desired path of the vehicle;
producing steering commands to be delivered to a steering actuator;
receiving an indication of an operating state of an implement or applicator attached to the vehicle; and
controlling a viewing mode of the display according to the operating state.
12. The guidance system as set forth in claim 11 , wherein the viewing mode is a field of view of the display, and the control device is configured to switch the display to a perspective view whenever the implement is raised and to switch the display to a plan view whenever the implement is lowered.
