VEHICLE CONTROL DEVICE

PROBLEM TO BE SOLVED: To eliminate the discontinuity of deceleration at the changeover of inertia traveling and non-inertia traveling, and to perform proper inertia traveling control.SOLUTION: A vehicle 10 comprises an engine 11 as a traveling drive source, and a clutch device 16 arranged at a power transmission path connected to an output shaft 12 of the engine 11. An engine ECU 31 brings the vehicle 10 into an inertia traveling state by decelerating the transmission power of the power transmission path by an operation of the clutch device 16 according to the establishment of a prescribed execution condition, and releases the inertial traveling state by the operation of the clutch device 16 according to the establishment of a prescribed release condition including at least an acceleration condition at inertia traveling. The engine ECU 31 also comprises a traveling determination part for determining that the vehicle 10 is in the inertia traveling state, and a clutch control part for performing semi-clutch control which brings an engagement degree of the clutch device 16 into a middle degree state at least at a start of the inertia traveling or immediately before the release of the inertia traveling in the inertia traveling state.SELECTED DRAWING: Figure 1 【課題】惰性走行と非惰性走行との切替に際して減速度の不連続性を解消し、ひいては適正なる惰性走行制御を実現する。【解決手段】車両１０は、走行駆動源としてのエンジン１１と、エンジン１１の出力軸１２に繋がる動力伝達経路に設けられるクラッチ装置１６とを備えている。エンジンＥＣＵ３１は、所定の実施条件の成立に応じて、クラッチ装置１６の操作により動力伝達経路の伝達動力を減少させて車両１０を惰性走行状態とし、惰性走行中において少なくともアクセル条件を含む所定の解除条件の成立に応じて、クラッチ装置１６の操作により惰性走行状態を解除する。また、エンジンＥＣＵ３１は、車両１０が惰性走行状態であることを判定する走行判定部と、惰性走行状態下において当該惰性走行の開始当初、及び惰性走行の解除直前の少なくともいずれかで、クラッチ装置１６の係合度合を中間度合状態とする半クラッチ制御を実施するクラッチ制御部と、を備える。【選択図】 図１
