ELECTRONIC CONTROL DEVICE

To provide an electronic control device which suppresses variations of a position of a work machine calculated on the basis of a satellite signal received by a GNSS terminal due to a change in communication environment of the GNSS, and can more quickly dissolve a positional error after improvement of the communication environment than a conventional one.SOLUTION: An electronic control device includes: a positioning quality determination unit 211 for determining a positioning quality on the basis of GNSS information; a travel state determination unit 212 for determining a travel state including a stop state on the basis of speed of the work machine; and a smoothing processing unit 213 for smoothing the GNSS information. The smoothing processing unit 213 switches the processing speed to low when a smoothing condition that the positioning quality is good and the travel state is a stop state is not satisfied, and switches the processing speed to high when a time corresponding to an update period passes after the smoothing condition has been satisfied.SELECTED DRAWING: Figure 3 【課題】ＧＮＳＳ端末が受信する衛星信号に基づいて算出される作業機械の位置が、ＧＮＳＳの通信環境の変化によってばらつくのを抑制し、その通信環境の改善後の位置誤差を従来よりも短時間に解消することが可能な電子制御装置を提供する。【解決手段】電子制御装置は、ＧＮＳＳ情報に基づいて測位品質の良否を判定する測位品質判定部２１１と、作業機械の速度に基づいて停止状態を含む走行状態を判定する走行状態判定部２１２と、ＧＮＳＳ情報に対して平滑化処理を施す平滑化処理部２１３と、を備える。平滑化処理部２１３は、測位品質が良でありかつ走行状態が停止状態である平滑化条件を満たさない場合に処理強度を弱に切り替え、平滑化条件を満たしてから更新周期に相当する時間が経過した場合に処理強度を強に切り替える。【選択図】図３
