Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent generation of mechanical noise from a waste gate valve due to vibration and prevent generation of electromagnetic noise from an actuator when a vehicle that has an internal combustion engine and an electric motor serving as driving sources is traveling in an electric motor drive mode.SOLUTION: When a vehicle is traveling in an electric motor drive mode in which the vehicle is driven by using only a motor 61 as a driving source, an engine 1 is automatically stopped, a target opening WGCMD of a waste gate valve 14 is set to be a predetermined opening WGX, and the waste gate valve 14 is controlled so that an opening WGO of the waste gate valve 14 detected by a valve opening sensor 23 corresponds to the target opening WGCMD. The predetermined opening WGX is set so as to satisfy a non-contact condition where an actual opening WGA does not reach a fully-closed opening or lower in the state where an error between the detected WG opening WGO and the actual opening WGA reaches an assumed maximum value EMAX.SELECTED DRAWING: Figure 5 【課題】内燃機関及び電動機を駆動源として備える車両が電動機駆動モードで走行しているときに、振動によってウエストゲート弁から機械的ノイズが発生すること、及びアクチュエータから電磁ノイズが発生することを防止する。【解決手段】車両がモータ６１のみを駆動源として駆動される電動機駆動モードでの走行中に、エンジン１が自動停止されるとともに、ウエストゲート弁１４の目標開度ＷＧＣＭＤが所定開度ＷＧＸに設定され、弁開度センサ２３によって検出されるウエストゲート弁１４の開度ＷＧＯが目標開度ＷＧＣＭＤと一致するようにウエストゲート弁１４が制御される。所定開度ＷＧＸは、検出されるＷＧ開度ＷＧＯと、実開度ＷＧＡとの誤差が想定される最大値ＥＭＡＸとなった状態において、実開度ＷＧＡが全閉開度以下とならない非接触条件を満たすように設定される。【選択図】図５
