Abstract
A management system for a work vehicle includes: a standard value calculation unit that calculates a standard value related to a detection value based on the detection value of a first attitude angle sensor when a work vehicle including the first attitude angle sensor stops at a predetermined position of a work site; and a diagnosis unit that determines presence or absence of abnormality of a second attitude angle sensor based on the standard value calculated by the standard value calculation unit and a detection value of the second attitude angle sensor when a work vehicle including the second attitude angle sensor stops at the predetermined position.
Claims17
A management system for a work vehicle, comprising a processor,
- the processor being configured to:
- calculate a standard value related to a detection value based on the detection value of a first attitude angle sensor when a work vehicle including the first attitude angle sensor stops at a predetermined position of a work site;
- determine presence or absence of abnormality of a second attitude angle sensor based on the standard value calculated and a detection value of the second attitude angle sensor when a work vehicle including the second attitude angle sensor stops at the predetermined position;
- acquire the detection value of the first attitude angle sensor each time the work vehicle including the first attitude angle sensor stops at the predetermined position;
- calculate the standard value based on a plurality of detection values determined to be normal among the plurality of detection values of the first attitude angle sensor acquired;
- and
- control the work vehicle to travel in the worksite based at least in part on detection data obtained by the first and second attitude angle sensors.
A management method for a work vehicle, comprising:
- calculating a standard value related to a detection value based on the detection value of a first attitude angle sensor when a work vehicle including the first attitude angle sensor stops at a predetermined position of a work site;
- and
- determining presence or absence of abnormality of a second attitude angle sensor based on the standard value and a detection value of the second attitude angle sensor when a work vehicle including the second attitude angle sensor stops at the predetermined position,
- wherein the standard value is calculated based on a plurality of detection values determined to be normal among the plurality of detection values of the first attitude angle sensor acquired each time the work vehicle including the first attitude angle sensor stops at the predetermined position;
- and
- controlling the work vehicle to travel in the worksite based at least in part on detection data obtained by the first and second attitude angle sensors.
A work vehicle comprising:
- a vehicle body;
- a travel device;
- an attitude angle sensor that is disposed in the vehicle body;
- and
- a processor,
- the processor being configured to:
- calculate a standard value related to a detection value based on the detection value of the attitude angle sensor when the travel device stops at a predetermined position of a work site;
- and
- determine presence or absence of abnormality of the attitude angle sensor based on the standard value calculated and the detection value of the attitude angle sensor when the travel device stops at the predetermined position after the standard value is calculated;
- calculate the standard value based on a plurality of detection values determined to be normal among the plurality of detection values of the attitude angle sensor acquired each time the travel device stops at the predetermined position;
- and
- control the work vehicle to travel in the worksite based at least in part on detection data obtained by the first and second attitude angle sensors.
