Abstract

The present invention is configured to comprise a position-measuring unit that uses a satellite positioning system to acquire position information regarding a work vehicle, wherein: a current-supplying pathway includes a first current-supplying pathway capable of supplying current to an electrical component, such as the position-measuring unit, from a battery via a first switch, and a second current-supplying pathway capable of supplying current to the position-measuring unit at least from the battery via a second switch; when the first switch is in an ON state, either the first current-supplying pathway or the second current-supplying pathway supplies current to the position-measuring unit from the battery; and when the first switch is in an OFF state, the second current-supplying pathway supplies current to the position-measuring unit from the battery via the second switch in an ON state.

Claims5

Dependent claims

An automatic travel system comprising:

a battery for power supply;
a position-measuring unit to acquire position information of a work vehicle with a use of a satellite positioning system;
and
a current-supplying pathway to supply current from the battery to the position-measuring unit,
wherein the current-supplying pathway includes a first current-supplying pathway capable of supplying current from the battery to electrical components including the position-measuring unit via a first switch and a second current-supplying pathway capable of supplying current at least from the battery to the position-measuring unit via a second switch different from the first switch,
wherein when the first switch is in an ON state, the current is supplied from the battery to the position-measuring unit in both the first current-supplying pathway and the second current-supplying pathway, and
wherein when the first switch is in an OFF state, the current is supplied from the battery to the position-measuring unit by the second current-supplying pathway via the second switch in an ON state, but the current is prevented from being supplied to other predetermined electrical components.
