PROBLEM TO BE SOLVED: To provide a full-closed position learning device for waste gate capable of performing a more precise study about a full-closed position of the waste gate valve while appropriately reflecting an error depending upon a variation of temperature of a device including the waste gate valve.SOLUTION: A full-closed position study device for a waste gate valve [WG valve] is operated in such a way that an opening WGA of a WG valve 14 is detected through a position of a rod 32 constituting a driving mechanism 30 for use in driving the WG valve 14. The detected opening WGA detected under a state in which the WG valve 14 is controlled to its full-closed position is studied as a full-closed position WGLRN for the WG valve 14. In addition, under a state less than a predetermined temperature decreased in which the temperatures of the WG valve 14 and the driving mechanism 30 are decreased, studying and updating for the full-closed position are allowed under a condition in which the detected opening WGA is changed to its opened side [steps 11 to 13 in Fig.5].SELECTED DRAWING: Figure 5

    【課題】ウェイストゲート弁を含むデバイス温度の変化に依存する誤差を適切に反映させながら、ウェイストゲート弁の全閉位置をより精度良く学習することができるウェイストゲート弁の全閉位置学習装置を提供する。【解決手段】本発明によるウェイストゲート弁(WG弁)の全閉位置学習装置では、WG弁14を駆動する駆動機構30を構成するロッド32の位置を介して、WG弁14の開度WGAが検出される。WG弁14が全閉位置に制御された状態で検出された検出開度WGAを、WG弁14の全閉位置WGLRNとして学習する。また、WG弁14及び駆動機構30の温度であるデバイス温度が低下するような所定の温度低下状態では、検出開度WGAが開き側に変化していることを条件として、全閉位置の学習及び更新を許可する(図5のステップ11〜13)。【選択図】図5
