摘要： A control device is configured to estimate a soot deposition amount (PM deposition amount) in a DPF for an exhaust purification device that is configured to purify exhaust of a diesel engine using the DPF, and determine a regeneration timing for the diesel engine based on the estimated PM deposition amount. As a technique of determining the regeneration timing, the control device employs a first determination technique of detecting that the PM deposition amount is a first threshold or more and a state in which the PM deposition amount is the first threshold or more has continued for a first predetermined time and a second determination technique of detecting that the PM deposition amount is a second threshold (>the first threshold) or more and a state in which the PM deposition amount is the second threshold or more has continued for a second predetermined time.

摘要： A first positioning processing unit executes independent positioning for calculating the position of a work vehicle on the basis of a satellite signal received from a satellite. A transmission processing unit transmits point positioning information to a base station server that selects one base station. An acquisition processing unit acquires correction information associated with the one base station from the base station server. A second positioning processing unit executes RTK positioning for calculating the current position of the work vehicle on the basis of the correction information. When the RTK positioning for the work vehicle based on first correction information associated with a first base station becomes possible, the transmission processing unit transmits, to the base station server, the point positioning information immediately before the RTK positioning becomes possible.

摘要： [Problem] To provide an automatic traveling method, a work vehicle, and an automatic traveling system that enable to proceed automatic traveling smoothly without creating a short automatic traveling route.
[Solution] A combine harvester 1 includes a control device 30 and a portable terminal 40. The control device 30 functions as an automatic traveling control unit 35 that performs automatic traveling on the basis of a created automatic traveling route 64. The portable terminal 40 is provided with a control device 41, and the control device 41 functions as a route creation unit 53 that creates, when a field outline 60 or an outline of an unworked region 61 is set as a target outline and one side that constitutes the target outline is set as a reference line 63, the automatic traveling route 64 as a route that is parallel to the reference line 63. The control device 41 also functions as a reference line setting unit 52 that sets, when one side that constitutes the target outline is equal to or more than a predetermined side length threshold, the one side as the reference line 63.-

摘要： A combine harvester includes a control device, and the control device functions as a travel route creation section which creates a travel route corresponding to a field, and as an automatic driving control section which controls automatic travel and automatic reaping along the travel route. The control device also functions as a lodging information setting section which automatically or manually sets lodging information associated with a lodging region in which grain culms are lodged in the field. The travel route creation section creates, on the basis of the lodging information, the travel route that includes reaping of the grain culms in the lodging region.
