If a negative determination is made in S202, it is determined that there is no need for an alarm at this point, so this routine is temporarily terminated. On the other hand, if a positive determination is made, the process proceeds to S203.
- the misrecognition threshold LE is a curve length as a threshold at which if the length of the curve alleviating unit 12 is longer than this, the driver tends to cause a risk of erroneous steering operation or acceleration / deceleration operation from a normal sense. That's it. How to determine this misunderstanding threshold LE will be described in detail later.

According to this, it is possible to issue an alarm only when it is necessary to alert the driver, and it is possible to realize more accurate driving support.
- ECU3 which performs said warning execution determination routine comprises a driving assistance control means in a present Example.
- an alarm is issued when all of the three determinations of S201 to S203 are positively determined. However, it is not always necessary that all three determinations be positively determined. Absent. For example, when information related to the shape of the curve is acquired before entering the curve, the determination in S201 is not necessary. The determination in S202 is also auxiliary.
- FIG. 5 shows a flowchart of a misrecognition threshold determination routine in the present embodiment.
- the design speed of the road on which the vehicle 1 is traveling is obtained in S301. This is the traveling speed assumed in the design of the road, and may be determined in consideration of the location of the road and the use situation. Further, this design speed may be considered to substantially match the speed limit on roads other than urban areas where substantial execution of this routine is expected.
- the design speed may be obtained by capturing the image information of the road sign with the sign recognition camera 7, or the road width is obtained from the GPS information of the car navigation system, and the design speed is calculated backward from the obtained road width. You may acquire by the method to do.
- the process of S301 ends, the process proceeds to S302.
- the minimum relaxation length Lmin according to the structure order is obtained.
- This minimum relaxation Lmin is determined as the minimum value of the relaxation length of the curve that can be taken with respect to the road design speed according to the structure decree. Accordingly, the minimum relaxation length Lmin of the road on which the vehicle 1 is traveling can be obtained from the design speed value obtained in S302.
- the error threshold LE is calculated by multiplying Lmin by a coefficient Gain.
- Gain is a constant determined by experiments or the like in consideration of the driver's feeling, and may be a value of 1.5 to 2.5, for example.
- the design speed of the road that is running is obtained using the sign recognition camera 7 or the car navigation system, and the minimum relaxation length Lmin of the road that is running is obtained from the obtained design speed. Further, the error threshold LE is determined by multiplying the minimum relaxation length Lmin by an appropriate gain. According to this, it is possible to immediately obtain information on the road on which the vehicle 1 is actually traveling, and to determine a high accuracy error threshold LE in real time based on this information.
- Example 3 Next, another method for determining the misunderstanding threshold LE will be described.
- This method is a method of accumulating data of the length Lclo of the curve relaxation portion 12 of the road on which the vehicle 1 actually travels, and determining the misunderstanding threshold LE from the accumulated data.
- FIG. 6 shows a flowchart for the misunderstanding threshold determination routine 2 used in this case.
- the values of Lp and Rp are obtained by the autonomous sensors such as the yaw rate sensor 4 and the wheel speed sensor 5 in the manner shown in the road shape estimation routine of FIG.
- the values of Lp and Rp are obtained from the GPS data of the car navigation system.
- either S401 or S402 may be performed. That is, the values of Lp and Rp may be obtained by either a method using an autonomous sensor or a method using a car navigation system.
- the length Lclo of the curve relaxation unit 12 is obtained by the calculation of S104 to S106 shown in FIG. 3, and this data is stored. To do.
- an error threshold LE is determined using the accumulated Lclo data.
- FIG. 7 shows an example of the distribution of the length Lclo of the accumulated curve relaxation portion 12.
- Lclo takes a value equal to or greater than Lmin due to the structure age, so the left end of the distribution curve is Lmin.
- the present embodiment based on the past data detected and accumulated by the autonomous sensor while driving the curve relaxation unit 12, or based on the future data detected and accumulated by the GPS of the car navigation system. Then, the distribution of the length Lclo of the curve relaxation unit 12 is obtained, and a value larger than the average value of the distribution by a predetermined amount is set as the error threshold LE. Therefore, it is possible to obtain a misrepresentation threshold LE that is more realistic based on the road on which the vehicle 1 has actually passed or data on which the vehicle 1 will actually pass.
- the use of the past data detected and accumulated by the autonomous sensor while traveling in the curve relaxation unit 12 and the future data detected and accumulated by the GPS of the car navigation system can be used, for example, by changing the route type. When the detected past data is no longer valid, it may be switched to future data detected by GPS.
- FIG. 8 the distribution of the relationship between the length Lclo of the large number of curve relaxation parts 12 acquired in the present embodiment and the maximum lateral G generated at that time is shown.
- the horizontal axis is the length Lclo of the curve relaxation portion 12.
- the vertical axis represents the maximum lateral G actually measured when the vehicle passes through each curve relaxation portion 12.
- the curves belonging to the lower left curve group C1 are normal curves, and it is considered that the driver does not feel much danger when passing through these curves.
- FIG. 9 is a graph showing temporal changes in vehicle speed Vs (t), lateral acceleration G, curvature radius R, curvature (1 / R), and steering angle when an actual driver passes a curve.

Description
前記曲率変動部を移動体が移動する際に、運転者に運転支援を行なう運転支援手段と、
前記曲率変動情報取得手段によって取得された、前記曲率変動部の形状についての情報に基づいて、前記運転支援手段が運転支援を行なうタイミングを決定する運転支援制御手段と、
を備えることを特徴とする。
そうすれば、曲率変動部の長さが運転者が有している感覚と比較して長く、運転者が曲率変動部の途中で、曲率変動部が終了したと判断することで生じる危険を抑制することができる。
図1は、本実施例に係る車両用運転支援システムの概略構成を示すブロック図である。本システムには、内燃機関を制御する電子制御コンピュータであるECU3が備えられている。ECU3は図示しないROM、RAM、CPU、入力ポート、出力ポート等を備え、ヨーレイトセンサ4、車輪速センサ5、白線認識カメラ6及び、標識認識カメラ7が電気的に接続されている。
L×R=A2・・・・・(1)
ここで、A2は、クロソイド曲線の形状を定める定数である。以下、道路形状についての情報取得の手順の例について説明する。
Lp=∫Vs(t)dt・・・・(2)
Lp×Rp=A2・・・・・・(3)
Lclo=A2/Rreal・・・・(4)
そして、最終的には、道路10のカーブ形状が以下のように特定される。
R(L)=A2/L (0≦L≦Lclo)・・・・・(5)
R(L)=Rreal (L≧Lclo)・・・・・・・(6)
(Vs(t))2≧Rreal×αd・・・・(7)
ここでRrealは真円カーブ部13の曲率半径である。また、αdは車両1の運転に危険が発生し始める危険横加速度であり、予め実験などにより定められる。この危険横加速度αdの値は、例えば0.4G程度でもよい。S202において否定判定された場合には、この時点で警報の必要性はないと判断されるので本ルーチンを一旦終了する。一方、肯定判定された場合は、S203に進む。
本実施例では、実施例1で説明した見誤り閾値LEの決定方法について説明する。図5には、本実施例における見誤り閾値決定ルーチンのフローチャートについて示す。本ルーチンが実行されると、S301において車両1が走行中の道路の設計速度が求められる。これは、道路の設計上想定されている走行速度であり、道路の場所や使用状況を考慮の上定められる場合もある。また、この設計速度は、本ルーチンの実質的な実行が期待されている、市街地以外の道路では、略制限速度に一致すると考えてよい。また、この設計速度は、標識認識カメラ7で道路標識の画像情報を取り込むことで取得してもよいし、カーナビゲーションシステムのGPS情報から道路幅を求め、求められた道路幅から設計速度を逆算する方法で取得してもよい。S301の処理が終了するとS302に進む。
次に、見誤り閾値LEを決める他の方法について説明する。この方法は、実際に車両1が走行した道路のカーブ緩和部12の長さLcloのデータを蓄積し、蓄積されたデータから見誤り閾値LEを決める方法である。この場合に用いる見誤り閾値決定ルーチン2についてのフローチャートを図6に示す。本実施例が実行されると、S401において、ヨーレイトセンサ4及び車輪速センサ5等の自律センサによって、図3の道路形状推定ルーチンに示した要領でLp及びRpの値を求める。また、S402においては、カーナビゲーションシステムのGPSデータより、Lp及びRpの値を求める。
次に、見誤り閾値LEを求める方法のさらに他の例について説明する。本実施例における方法は、実際の運転者が、カーブにおいて危険を感じた現場における各パラメータのデータを用いて見誤り閾値LEを求める方法である。図9は、実在の運転者がカーブを通過した際の、車速Vs(t)、横加速度G、曲率半径R、曲率(1/R)、舵角の時間的変化を示したグラフである。このグラフの曲率半径R及び曲率(1/R)の変化より、車両1がカーブ緩和部12を通過するのに要した時間は4.8secであることが分かる。また、その際の車速が46km/hであることより、カーブ緩和部12の長さLcloは61mであることが分かる。
