PROBLEM TO BE SOLVED: To enable an engine to stop operating at a time of the occurrence of abnormality in a suspension control unit.SOLUTION: An engine control unit 30 automatically stops an engine 20 if an operation stop condition is satisfied and automatically restarts the engine 20 if an operation restart condition is satisfied. Furthermore, if a suspension control unit 50 transmits a stop prohibition request signal for prohibiting the engine 20 from being automatically stopped so as to drive a motor 45 to the engine control unit 30, the engine control unit 30 controls the engine 20 to continue operating even if the stop condition is satisfied. Furthermore, if determining that abnormality occurs in the suspension control unit 50, the engine control unit 30 ignores the stop prohibition request signal, even if the stop prohibition request signal is transmitted when the stop condition is satisfied, and automatically stops the engine 20. 【課題】サスペンション制御装置異常時に、機関の運転停止を可能にすること。【解決手段】機関制御装置３０は、運転停止条件が成立したとき機関２０を自動停止し、運転再開条件が成立したとき自動再開する。更に、サスペンション制御装置５０からモータ４５ａを駆動するために自動停止を禁止する停止禁止要求信号が機関制御装置に送信されて来ている場合、停止条件が成立しても運転を継続する。加えて、サスペンション制御装置に異常が発生していると判定した場合には、停止条件が成立しているときに停止禁止要求信号が送信されて来ていても、その停止禁止要求信号を無視して自動停止させる。【選択図】図１
