To provide an automatic stop/restart device of an internal combustion engine capable of avoiding failure accompanying an operation from a parking range of a shift operation member during automatic stop of the internal combustion engine on a slope, and extending an automatic stop time as much as possible, in a case when a vehicle has a hydraulic transmission and a parking mechanism.SOLUTION: A vehicle including an automatic stop/restart device of an internal combustion engine has: a hydraulic continuously variable transmission for changing a speed of power of the internal combustion engine by utilizing a hydraulic pressure increased by rotary driving force of the internal combustion engine; and a parking mechanism for keeping the vehicle in a stop state by locking rotation of a power transmission member between the internal combustion engine and a drive wheel when a shift position is a P range. Restart of the internal combustion engine is carried out when an inclination angle AIV of the vehicle is a prescribed value AREF or more (YES in S14), and automatic stop of the internal combustion engine is continued when the inclination angle AIV is less than the prescribed value AREF (NO in S14), in a case when the shift position is the P range (YES in S12), and an OFF operation is performed on a brake during the automatic stop of the internal combustion engine.SELECTED DRAWING: Figure 6

    【課題】車両が油圧式の変速機及びパーキング機構を有する場合において、坂道での内燃機関の自動停止中におけるシフト操作部材のパーキングレンジからの操作に伴う不具合を回避し、自動停止時間を可能な限り延長できる内燃機関の自動停止再始動装置を提供する。【解決手段】内燃機関の自動停止再始動装置を備える車両は、内燃機関の回転駆動力で昇圧される油圧を利用して内燃機関の動力を変速する油圧式の無段変速機と、シフト位置がPレンジのときに内燃機関と駆動輪の間の動力伝達部材の回転を係止することで車両を停車状態に保持するパーキング機構とを有し、内燃機関の自動停止中、シフト位置がPレンジ(S12YES)でブレーキがオフ操作された場合において、車両の傾斜角AIVが所定値AREF以上のときに(S14YES)内燃機関の再始動を実行し、傾斜角AIVが所定値AREF未満のときに(S14NO)内燃機関の自動停止を継続する。【選択図】図6
