An acquisition processing unit acquires, when a work vehicle performs autonomous travel according to a target route, distance information relating to a distance to a detection target that is detected by an obstacle sensor, and image information relating to a capture image of the detection target that is captured by a camera. A determination processing unit determines a type of the detection target based on the image information. A countermeasure processing unit causes the work vehicle to execute countermeasure processing according to the type of the detection target and the distance information.

An automatic traveling system causes a work vehicle to automatically travel in a work area in a case where the work vehicle satisfies a traveling start condition, and causes the work vehicle to automatically travel in a non-work area in a case where predetermined confirmation operation or confirmation action by a worker is performed.

An autonomous work machine including a working unit, the autonomous work machine comprising: a detection unit configured to detect a rear work target object of the autonomous work machine; a determination unit configured to determine a state of the rear work target object based on a detection result of the detection unit; and a control unit configured to control a travel route of the autonomous work machine based on a determination result of the determination unit.

An agricultural machine includes a turn generation system that identifies a turn start point and turn end point that indicate the starting point and ending point, respectively, of a turn that the agricultural machine will make to transition from a current pass to a subsequent pass. The guidance system identifies a turn contour and projects that contour onto a headland area of the field. The turn generation system generates a turn path based upon the turn starting and ending points and the turn path contour.

A control method for a robot mower includes controlling the robot mower to work within a lawn having a plurality of unmowed areas, and controlling the robot mower to turn upon detecting either a boundary of the lawn or an obstacle. When controlling the robot mower to turn, the method includes obtaining a target position determined according to the unmowed region with the largest area. The method then calculates a turning angle of the robot mower according to a current position and a current orientation of the robot mower and the target position; controls the robot mower to turn according to the turning angle; and control the robot mower to move forward.
