AI summary

A method for controlling a work vehicle is a method for controlling the work vehicle to which a work machine is detachably attached and includes determining a match/mismatch between first information and second information and notifying a result of determination. The first information is information about a first work machine that is attached as the work machine to the work vehicle at a first time point in the past. The second information is information about a second work machine that is attached as the work machine to the work vehicle at the current time point.
