Automatic travel system for work vehicle

Abstract

In an automatic travel system for a work vehicle, an automatic travel control unit performs automatic travel control when a condition determination unit determines that a start condition for first automatic travel control is satisfied at a time when the work vehicle (1) reaches an entry area (Aa) for a parallel route (P1). When the condition determination unit determines that a condition for starting the first automatic travel control is not satisfied, the first automatic travel control unit performs the first automatic travel control for causing the work vehicle (1) to automatically travel along the parallel path (P1) in a work state. In the present invention, automatic zigzag travel control for causing a work vehicle (1) to perform zigzag travel by a combined operation of a forward / reverse switching operation and a steering operation of the work vehicle (1) is executed so that a condition for starting the first automatic travel control is satisfied.

Description

technical field [0001] The present invention relates to an automatic driving system for work vehicles capable of automatic driving of work vehicles such as tractors and combines. Background technique [0002] The automatic driving system for the work vehicle as described above includes: a control unit that automatically drives the work vehicle along a work route generated corresponding to the work area; a position detection unit that detects the position of the work vehicle; and azimuth detection. part, which detects the azimuth angle of the work vehicle. In addition, the control unit is configured so that, when an instruction to start work is given while the work vehicle is at a travel start position set on a field around the work area, the distance between the extension line of the work path and the position of the work vehicle The travel of the work vehicle is controlled to reduce the deviation, and the work vehicle is automatically driven from the travel start position ...

Problems solved by technology

[0005] On the other hand, in order to extend the distance from the driving start position on the field head to the work start position of the work path, the head of the field is widened and the work area is narrowed. Therefore, for example, when the work area is a field crop area, the planting area becomes smaller. Narrow and crop yields are reduced

Or, when the work area is a reciprocating work area where the work vehicle travels back and forth, and the field head is a surrounding work area where the work vehicle travels around the head of the field, the number of turns of the work vehicle around the head of the field increases, thereby reducing the work efficiency.

Especially when the work vehicle is driven around manually, the burden on the user increases
