Therefore, even if the foot brake is not operated, it is determined that the vehicle is decelerating when the accelerator is turned off and the vehicle is decelerated by the engine brake.
- the CPU 41 performs braking control of the vehicle so that the deceleration of the vehicle is completed at the deceleration termination target point by an aspect as close as possible to the ideal deceleration curve shown in FIG. Specifically, the CPU 41 transmits an instruction signal to the vehicle control ECU 19 via the CAN, thereby performing a downshift and a brake operation, and performing a braking control of the vehicle. As a result, the vehicle can be decelerated to an appropriate speed with an appropriate deceleration without sudden acceleration / deceleration. In particular, in a hybrid vehicle or an EV vehicle, the battery can be charged by the regenerative brake. It becomes possible to carry out with efficiency.

Specifically, the position coordinates of the deceleration end point where the vehicle has finished decelerating are acquired (FIG. 2).
- the CPU 41 searches the learning DB 32 and determines whether or not learning data corresponding to the current vehicle deceleration action is already stored in the learning DB 32. Specifically, referring to the learning DB 32 (FIG. 3), when there is learning data that stores the deceleration end point in the same direction of the same link, the learning data corresponding to the deceleration action of the vehicle is already present. It determines with having memorize
- the CPU 41 stores the learning data of the deceleration control point specified in S21 in the learning DB 32 as learning data regarding the new deceleration control point.

- the CPU 41 obtains the road type (the narrow street, the general road, the main road, etc.) of the road having the deceleration control point specified in S21 and the road type of the intersection road intersecting with the road. If the deceleration control point is in front of the curve or near the toll gate and not near the intersection, there is no intersection road, so only the road type of the road with the deceleration control point is acquired.
- the CPU 41 sets a variation range based on the road type acquired in S24.

For example, when the road type of the road with the deceleration control point is a narrow street and the road type of the intersection road is a narrow street, the variation range is set to 15 m. On the other hand, when the road type of the road with the deceleration control point is the main road and the road type of the intersection road is the main road, the variation range is set to 50 m.
- the variation range is set to a wider range as the combination of roads is predicted to cause a large amount of traffic and variations in deceleration end points are likely to occur (the combination in the lower part of FIG. 9).
- the variation range is set only by the road type of the road with the deceleration control point. For example, it is 15 m for a narrow street, 30 m for a general road, and 50 m for a main road.
- the CPU 41 searches the learning DB 32, and within the variation range set in S25 from the deceleration end point included in the learning data corresponding to the current vehicle deceleration action already stored in the learning DB 32. Then, it is determined whether there is a deceleration end point of the current deceleration travel. In addition, when there are a plurality of learning data corresponding to the deceleration action of the current vehicle already stored in the learning DB 32, it is within the variation range set in S25 from all the deceleration end points included in each learning data.

- the range considered as the same deceleration end point is set. It is possible to determine whether the road is likely to vary, and based on the determination result, it is possible to appropriately set a range that is regarded as the same deceleration end point.
- the deceleration end target point since the point where the distance of the standard deviation is moved forward in the traveling direction from the average value of the history of the deceleration end points stored as the same deceleration end point is set as the deceleration end target point, the content of the deceleration action varies. Even if it has occurred, it is possible to set an appropriate deceleration end target point.
- a deceleration end point for example, a stop position of the vehicle
- the range considered as the same deceleration end point is set wider, so the road type is more likely to vary in the content of deceleration action from the road type,

Abstract
Description
尚、「減速終了地点を記憶する」とは、減速終了地点自体の位置座標を記憶することに加えて、減速終了地点の位置を示唆する地点(例えば減速終了地点の手前側や進行方向側に一定距離移動させた地点)の位置座標を記憶する構成としても良い。
尚、「進行方向前方」とは、車両が移動する道なりの道路に沿った車両の進行方向前方の範囲としても良いし、経路と関係なく車両の進行方位に対して所定角度以内の範囲としても良い。更に、案内経路が設定されている場合には案内経路に沿った車両の進行方向前方の範囲としても良い。
また、「運転を支援する」とは、車両に対する加速や減速等の駆動に関する制御を行う場合に加えて、表示案内や音声案内を行う場合も含む。
現在位置検出部11は、GPS21、車速センサ22、ステアリングセンサ23、ジャイロセンサ24等からなり、現在の車両の位置、方位、車両の走行速度、現在時刻等を検出することが可能となっている。ここで、特に車速センサ22は、車両の移動距離や車速を検出する為のセンサであり、車両の駆動輪の回転に応じてパルスを発生させ、パルス信号をナビゲーションECU13に出力する。そして、ナビゲーションECU13は発生するパルスを計数することにより駆動輪の回転速度や移動距離を算出する。尚、上記4種類のセンサをナビゲーション装置1が全て備える必要はなく、これらの内の1又は複数種類のセンサのみをナビゲーション装置1が備える構成としても良い。
尚、地図情報DB31や学習DB32を外部のサーバに記憶し、ナビゲーション装置1が通信によりデータの更新や取得を行う構成としても良い。
一方、減速終了地点Aから減速終了地点Bまでの距離Dがバラつき距離より大きい場合には、減速終了地点Bは異なる要因に基づく減速行動又はイレギュラーな減速行動に基づくものであると推定し、減速終了地点Bは異なる減速終了地点に対する学習データとして記憶するか、或いは学習データとして記憶しない。その結果、次回以降に車両が同一リンクを同一方向に走行した場合には、前述した車両制御処理(図5)において、減速終了地点Aのみを用いて減速終了目標地点が設定されることとなる。
また、車両の進行方向前方に減速終了目標地点がある場合であって、車両において減速行動が行われた場合に、減速終了目標地点で車両の減速が終了するように制動制御するので、車両が減速行動を行う場合において該行動を適切に支援することが可能となる。即ち、車両が減速行動を行う必要のない状況では、不要な支援が行われる虞がない。
また、減速終了地点は、車両が停止した地点、又は減速から加速に変化した地点とするので、車両が最終的に停止したか否かに関わらず適切な減速終了目標地点を設定することが可能となる。
また、減速終了地点がある道路の道路種別と該道路に交差する交差道路の道路種別との組み合わせに基づいて、同一の減速終了地点とみなす範囲を設定するので、道路種別から減速行動の内容にばらつきが生じ易い道路であるか否かを判定することができ、その判定結果に基づいて同一の減速終了地点とみなす範囲を適切に設定することが可能となる。
また、同一の減速終了地点として記憶された減速終了地点の履歴の平均値から進行方向前方に標準偏差分の距離を移動した地点を減速終了目標地点に設定するので、減速行動の内容にばらつきが生じていた場合であっても適切な減速終了目標地点を設定することが可能となる。また、平均値よりも進行方向前方側に設定するので、車両の運転支援を行う場合に、減速目標地点よりも進行方向前方側に減速の終了地点(例えば車両の停止位置)がくること、即ち車両の再加速が行われることを防止することが可能となる。
また、減速終了地点がある道路が交通量の多い道路種別である程、同一の減速終了地点とみなす範囲を広く設定するので、道路種別から減速行動の内容にばらつきが生じ易い道路である程、同一の減速終了地点とみなす範囲をより広い範囲に設定することが可能となる。従って、減速行動の内容のばらつきを考慮して、減速終了目標地点を設定することが可能となる。
例えば、本実施形態では、車両に対する運転支援として車両に対する制動制御を行っているが、表示案内や音声案内を行う構成としても良い。具体的には、減速終了目標地点までに理想の減速曲線を描いて車両が減速するように、減速のタイミングや量を指示する案内を行う。
運転支援手段は、車両の進行方向前方に減速終了目標地点がある場合であって、車両において減速行動が行われた場合に、減速終了目標地点で前記車両の減速が終了するように制動制御することを特徴とする。
上記構成を有する運転支援システムによれば、車両の進行方向前方に減速終了目標地点がある場合であって、車両において減速行動が行われた場合に、減速終了目標地点で車両の減速が終了するように制動制御するので、車両が減速行動を行う場合において該行動を適切に支援することが可能となる。即ち、車両が減速行動を行う必要のない状況では、不要な支援が行われる虞がない。

上記構成を有する運転支援システムによれば、減速終了地点は、車両が停止した地点、又は減速から加速に変化した地点とするので、車両が最終的に停止したか否かに関わらず適切な減速終了目標地点を設定することが可能となる。

上記構成を有する運転支援システムによれば、減速終了地点がある道路の道路種別と該道路に交差する交差道路の道路種別との組み合わせに基づいて、同一の減速終了地点とみなす範囲を設定するので、道路種別から減速行動の内容にばらつきが生じ易い道路であるか否かを判定することができ、その判定結果に基づいて同一の減速終了地点とみなす範囲を適切に設定することが可能となる。
目標設定手段は、同一の減速終了地点として記憶された減速終了地点の履歴の平均値と標準偏差を算出し、同一の減速終了地点として記憶された減速終了地点の履歴の平均値から進行方向前方に標準偏差分の距離を移動した地点を減速終了目標地点に設定することを特徴とする。
上記構成を有する運転支援システムによれば、同一の減速終了地点として記憶された減速終了地点の履歴の平均値から進行方向前方に標準偏差分の距離を移動した地点を減速終了目標地点に設定するので、減速行動の内容にばらつきが生じていた場合であっても適切な減速終了目標地点を設定することが可能となる。また、平均値よりも進行方向前方側に設定するので、車両の運転支援を行う場合に、減速目標地点よりも進行方向前方側に減速の終了地点(例えば車両の停止位置)がくること、即ち車両の再加速が行われることを防止することが可能となる。
所定範囲は、特定された減速終了地点がある道路が交通量の多い道路種別である程、所定範囲を広い範囲に設定することを特徴とする。
