Zusammenfassung:	PROBLEM TO BE SOLVED: To improve fuel economy by elongating a time at which an accelerator operation is turned off as much as possible.SOLUTION: A target vehicle speed Va when passing a passing point Pa in front of a course of an own vehicle is set, inertia traveling which is performed by the turn-off of an accelerator operation is assumed, and a vehicle speed transition Vi at which a vehicle speed is lowered according to a moving distance is estimated. A vehicle speed threshold Vth which coincides with a target vehicle speed Va at arrival to the passing point Pa, and is lowered along the vehicle speed transition Vi as approximating the passing point Pa is set. Then, when the vehicle speed is higher than the vehicle speed threshold Vth when approximating the passing point Pa, and the accelerator operation is turned on, a driver is urged to turn off the accelerator operation.SELECTED DRAWING: Figure 1 【課題】アクセル操作をオフにしている時間をできるだけ長くし、燃費の向上を図る。【解決手段】自車進路前方の通過地点Ｐａを通過するときの目標車速Ｖａを設定し、アクセル操作をオフにして惰性走行すると仮定し、移動距離に応じて低下してゆく車速推移Ｖｉを推定する。また、通過地点Ｐａに到達するときに目標車速Ｖａと一致し、且つ通過地点Ｐａに近づくほど車速推移Ｖｉに沿って低下してゆく車速閾値Ｖｔｈを設定する。そして、通過地点Ｐａに近づく際に、車速が車速閾値Ｖｔｈより高く、且つアクセル操作がオンであるときに、アクセル操作のオフを運転者に促す。【選択図】図１
