WORK VEHICLE, CONTROL DEVICE FOR WORK VEHICLE, AND METHOD FOR DETERMINING STATE OF WORK VEHICLE
To provide a method for detecting the condition of a work vehicle to control exhaust temperature.SOLUTION: A method for determining the condition of a work vehicle comprises detecting a rotational speed of an engine of the work vehicle during a predetermined time period, determining a maximum rotation speed that is the maximum value of the rotation speed in the time period and a minimum rotation speed that is the minimum value of the rotation speed in the time period, determining a parameter representing a fuel injection amount of the engine during the time period, determining an amount of variation that is the difference between the maximum value of the parameter in the time period and the minimum value of the parameter in the time period, determining that the work vehicle is in an operating state when the difference between the maximum rotation speed and the minimum rotation speed exceeds a rotation speed threshold or the amount of variation exceeds a variation amount threshold.SELECTED DRAWING: Figure 4
【課題】排気温度を制御するために作業車両の状態を検出する方法を提供する。【解決手段】作業車両の状態判定方法は、作業車両のエンジンの回転速度を予め定めた時間長の期間において検出し、期間における回転速度の最大値である最大回転速度と期間における回転速度の最小値である最小回転速度とを求め、該期間においてエンジンの燃料噴射量を表すパラメータを求め、該期間におけるパラメータの最大値と該期間におけるパラメータの最小値との差である変動量を求め、最大回転速度と最小回転速度との差が回転速度閾値を超えるか、変動量が変動量閾値を超えるときに、作業車両は、稼働状態であると判定することを含む。【選択図】図４
