しかしながら、上記特許文献1記載の従来装置によれば、障害物が存在し、障害物を回避する場合には、車線を逸脱しても警報が発せられないため、回避操作時に不適切な車両操作が行われても警報が発せられない。   However, according to the conventional apparatus described in Patent Document 1, when an obstacle is present and an obstacle is to be avoided, an alarm is not issued even if the vehicle departs from the lane. No warning is issued even if

この第一の態様において、上記白線検出手段によって白線が検出されなかった領域とは、例えば、白線上に駐車車両などの障害物が存在する領域や、長年の交通や風雪により白線が擦れ消えてしまった領域や、元々白線が描かれていない領域などを指す。   In this first aspect, the area where the white line is not detected by the white line detecting means is, for example, an area where an obstacle such as a parked vehicle is present on the white line, or a white line rubbed off due to long-time traffic or wind and snow. This refers to areas that have been closed or areas that are not originally drawn with white lines.

また、この第一の態様において、上記制御手段は、A)自車両が上記白線検出手段によって検出された白線と上記設定手段によって設定された仮想白線とから成る走行車線を逸脱したときに警報を発する、及び/又は、B)自車両が上記白線検出手段によって検出された白線と上記設定手段によって設定された仮想白線とから成る走行車線の略中央を走行するように操舵トルクを付与する。   Further, in this first aspect, the control means gives an alarm when the vehicle departs from a traveling lane composed of the white line detected by the white line detection means and the virtual white line set by the setting means. B) The steering torque is applied so that the host vehicle travels substantially in the center of the travel lane composed of the white line detected by the white line detection means and the virtual white line set by the setting means.

ここで、上記回避点は、上記静止物と自車両との交錯可能性が高い場合ほど自車両が余裕をもって該静止物を回避できるように、例えば、1)上記静止物の検出点と自車両の相対速度が大きいほど自車両寄りに設定される、及び/又は、2)自車両から上記静止物の検出点までの距離が短いほど自車両寄りに設定される。   Here, the avoidance point is, for example, 1) the detection point of the stationary object and the own vehicle so that the higher the possibility of crossing the stationary object and the own vehicle, the more likely the own vehicle can avoid the stationary object. The higher the relative speed is, the closer to the own vehicle, and / or 2) the shorter the distance from the own vehicle to the stationary object detection point, the closer to the own vehicle.

この第二の態様によれば、走行車線に障害物が存在する場合に、この障害物を回避するように仮想白線が設定されるため、車線維持制御や車線逸脱警報などの車線に基づく運転支援を継続しながら障害物を回避することが可能となる。換言すれば、車線に基づく運転支援を継続するだけで、障害物回避が実現される。   According to this second aspect, when there is an obstacle in the traveling lane, the virtual white line is set so as to avoid this obstacle, so driving assistance based on the lane such as lane keeping control or lane departure warning It is possible to avoid obstacles while continuing. In other words, obstacle avoidance is realized simply by continuing driving support based on the lane.

An apparatus can be provided.

以下、本発明を実施するための最良の形態について、添付図面を参照しながら実施例を挙げて説明する。なお、レーンキープアシスト(LKA;車線維持支援)装置及びレーンデパーチャワーニング(LDW;車線逸脱警報)装置の基本概念、主要なハードウェア構成、作動原理、及び基本的な制御手法等については当業者には既知であるため、詳しい説明を省略する。   Hereinafter, the best mode for carrying out the present invention will be described with reference to the accompanying drawings. Those skilled in the art are familiar with the basic concept, main hardware configuration, operating principle, basic control method, etc. of the lane keep assist (LKA) and lane departure warning (LDW) device. Since it is already known, detailed explanation is omitted.

以下、図1〜11を用いて、本発明の一実施例に係る車両用運転支援装置について説明する。   A vehicle driving support apparatus according to an embodiment of the present invention will be described below with reference to FIGS.

図1は、本実施例に係る車両用運転支援装置100の概略構成図である。車両用運転支援装置100は、例えばCCDカメラなどの画像撮像機器を利用して少なくとも自車両が走行中の車線の左右境界線として道路上に描かれた白線を検出する白線検出部101と、例えばレーザレーダやミニ波レーダなどを利用して自車両周辺の物体を検出する物体検出部102とを有する。   FIG. 1 is a schematic configuration diagram of a vehicle driving support apparatus 100 according to the present embodiment. The vehicle driving support apparatus 100 uses, for example, a white line detection unit 101 that detects a white line drawn on a road as a left-right boundary line of a lane in which the host vehicle is traveling, using an image capturing device such as a CCD camera, for example. An object detection unit that detects an object around the host vehicle using a laser radar, a mini-wave radar, or the like.

物体検出部102は、静止物及び移動体の双方を検出すると共に、自車両と対象物との相対速度及び距離を算出する。本実施例において、物体検出部102は、特に、先行車両、対向車両、走行車線外側のガードレール、走行車線沿道の建築物、中央分離帯、中央分離帯上の建築物、走行車線上の障害物、などを検出する。   The object detection unit 102 detects both a stationary object and a moving object, and calculates the relative speed and distance between the host vehicle and the target object. In the present embodiment, the object detection unit 102 includes, in particular, a preceding vehicle, an oncoming vehicle, a guard rail outside the traveling lane, a building along the traveling lane, a median strip, a building on the median strip, and an obstacle on the travel lane. , Etc.

車両用運転支援装置100は、更に、車両用運転支援装置100の各構成要素を統括的に制御する制御部103を有する。制御部103は、例えば、ECU(Electronic Control Unit;電子制御装置)である。   The vehicle driving support apparatus 100 further includes a control unit 103 that comprehensively controls each component of the vehicle driving support apparatus 100. The control unit 103 is, for example, an ECU (Electronic Control Unit).

車両用運転支援装置100は、更に、自車両が目標車線を逸脱したときに車両乗員(特に、運転者)に警報を発する警報部104と、レーンキープ制御実施中に自車両が目標車線の略中央を走行するように操舵トルクを付与する操舵制御部105とを有する。   The vehicle driving support apparatus 100 further includes an alarm unit 104 that issues an alarm to a vehicle occupant (especially a driver) when the host vehicle deviates from the target lane, and the host vehicle is an abbreviation of the target lane during lane keeping control. And a steering control unit 105 that applies a steering torque so as to travel in the center.

次いで、このような構成の本実施例に係る車両用運転支援装置100の動作について説明する。図2は、本実施例に係る車両用運転支援装置100の動作の流れを示すフローチャートである。   Next, the operation of the vehicle driving support apparatus 100 according to this embodiment having such a configuration will be described. FIG. 2 is a flowchart showing an operation flow of the vehicle driving support apparatus 100 according to the present embodiment.

まず、制御部103は、白線検出部101によって自車両走行車線の白線が検出されたか否かを判断する(S201)。   First, the control unit 103 determines whether or not the white line detection unit 101 has detected a white line of the host vehicle traveling lane (S201).

白線が検出された場合(S201の「YES」)、従来通り、検出された白線により規定される車線が目標車線として設定される(S206)。   When the white line is detected (“YES” in S201), the lane defined by the detected white line is set as the target lane as usual (S206).

他方、自車両走行車線を認識できる程度に白線が検出されなかった場合(S201の「NO」)、次いで、制御部103は、物体検出部102によって先行車両の存在が検出されたか否かを判断する(S202)。   On the other hand, when the white line is not detected to such an extent that the host vehicle traveling lane can be recognized (“NO” in S201), the control unit 103 then determines whether the presence of the preceding vehicle is detected by the object detection unit 102. (S202).

先行車両が検出された場合(S202の「YES」)、制御部103は、物体検出部102によって検出された先行車両の移動軌跡を演算する(S203)。   When the preceding vehicle is detected (“YES” in S202), the control unit 103 calculates the movement locus of the preceding vehicle detected by the object detection unit 102 (S203).

そして、制御部103は、先行車両の移動軌跡と進行方向ベクトルとに基づいて、先行車両の予想移動軌跡を演算し、これら移動軌跡及び予想移動軌跡に基づいて走行車線の仮想白線を描くことによって、走行車線を推定し、目標車線として設定する(S206)。   Then, the control unit 103 calculates an expected movement locus of the preceding vehicle based on the movement locus of the preceding vehicle and the traveling direction vector, and draws a virtual white line of the traveling lane based on the movement locus and the expected movement locus. The travel lane is estimated and set as the target lane (S206).

このように先行車両の存在から車線を推定する場合の一例を図3〜5に示す。図3において、実線はガードレールや段差等の道路境界線を示し、破線は自車両Aが検出できなかった白線位置を示している。   An example of estimating the lane from the presence of the preceding vehicle is shown in FIGS. In FIG. 3, a solid line indicates a road boundary line such as a guard rail or a step, and a broken line indicates a white line position where the host vehicle A cannot be detected.

自車両Aは、図4に示すように、先行車両Bの後端を検出すると、これら先行車両Bの検出点P(白丸)の移動軌跡T及び先行車両Bの移動ベクトルVを算出する。さらに、自車両は、先行車両Bの移動軌跡T及び移動ベクトルVから、先行車両Bの予想移動軌跡Tを演算する。 When the host vehicle A detects the rear end of the preceding vehicle B, as shown in FIG. 4, the own vehicle A calculates the movement locus T b of the detection point P 1 (white circle) of the preceding vehicle B and the movement vector V 1 of the preceding vehicle B. To do. Further, the vehicle from movement track T b and the movement vector V 1 of the preceding vehicle B, and calculating the expected movement locus T a of the preceding vehicle B.

次いで、自車両Aは、図5に示すように、先行車両Bの移動軌跡T及び予想移動軌跡Tから、走行車線の仮想白線VLを描く。この仮想白線VLは、例えば、先行車両Bの移動軌跡T及び予想移動軌跡Tの左右端からそれぞれ所定距離外側へ離れた位置に引かれる。 Then, the own vehicle A, as shown in FIG. 5, the movement track T b and predicted movement locus T a of the preceding vehicle B, draw a virtual white line VL of the travel lane. This virtual white line VL, for example, drawn from the left and right ends of the movement trajectory T b and predicted movement locus T a of the preceding vehicle B at a position away a predetermined distance outwardly respectively.

さらに、本実施例において、この仮想白線VLは、一例として、図5に示すように、自車両から比較的近い近領域(例えば、自車両前方7〜17メートルの範囲)と、この近領域より奥側の遠領域(例えば、自車両前方17〜27メートルの範囲)とに分けてそれぞれ求められる。   Furthermore, in this embodiment, the virtual white line VL is, as an example, as shown in FIG. 5, a near area relatively close to the own vehicle (for example, a range of 7 to 17 meters ahead of the own vehicle) and the near area. It is determined separately for the far region (for example, a range of 17 to 27 meters ahead of the host vehicle).

このようにして設定された仮想白線VLにより規定される車線が、推定された走行車線として目標車線に設定される。   The lane defined by the virtual white line VL set in this way is set as the target lane as the estimated travel lane.

図2に戻る。先行車両が検出されなかった場合(S202の「NO」)、次いで、制御部103は、対向車両やガードレールなど車線を推定するのに用いることができる物体が物体検出部102によって他に検出されたか否かを判断する(S204)。   Returning to FIG. When the preceding vehicle is not detected (“NO” in S202), the control unit 103 then detects whether another object that can be used to estimate the lane such as the oncoming vehicle or the guardrail is detected by the object detection unit 102. It is determined whether or not (S204).

白線も検出されず、先行車両も検出されず、更に、他に車線の推定に利用可能な物体が何も検出されなかった場合(S204の「NO」)、特段の制御を行わず、本フローの1ルーチンを終了する。   If no white line is detected, no preceding vehicle is detected, and no other object that can be used for estimating the lane is detected ("NO" in S204), no special control is performed and this flow is performed. 1 routine is completed.

他方、白線及び先行車両は検出されなかったが、対向車両やガードレールなどから車線の推定が可能な場合(S204の「YES」)、次いで、制御部103は、検出された対向車両やガードレールの移動軌跡や回避点を演算する(S205)。   On the other hand, when the white line and the preceding vehicle are not detected, but the lane can be estimated from the oncoming vehicle or the guardrail (“YES” in S204), the control unit 103 then moves the detected oncoming vehicle or guardrail. The locus and the avoidance point are calculated (S205).

そして、制御部103は、対向車両については進行方向ベクトルから対向車両の予想移動軌跡を演算し、ガードレールや段差などの道路境界線についてはこれらを回避するための回避点を設定し、これら予想移動軌跡及び回避点に基づいて走行車線の仮想白線を描くことによって、走行車線を推定し、目標車線として設定する(S206)。   Then, the control unit 103 calculates an expected movement trajectory of the oncoming vehicle from the traveling direction vector for the oncoming vehicle, sets an avoidance point for avoiding these on the road boundary lines such as a guardrail and a step, and the expected movement By drawing a virtual white line of the travel lane based on the trajectory and the avoidance point, the travel lane is estimated and set as the target lane (S206).

このように対向車両及びガードレールの存在から車線を推定する場合の一例を図6〜8に示す。図6において、実線はガードレールや段差等の道路境界線を示し、破線は自車両Aが検出できなかった白線位置を示している。   Examples of estimating the lane from the presence of the oncoming vehicle and the guard rail in this way are shown in FIGS. In FIG. 6, a solid line indicates a road boundary line such as a guardrail or a step, and a broken line indicates a white line position where the host vehicle A cannot be detected.

自車両Aは、図7に示すように、対向車両Cの前端を検出すると、これら対向車両Cの検出点P(白丸)の移動履歴から対向車両Cの移動ベクトルVを算出する。さらに、自車両Aは、対向車両Cの移動ベクトルVから、対向車両Cの予想移動軌跡Tを演算する。 As shown in FIG. 7, when the own vehicle A detects the front end of the oncoming vehicle C, the own vehicle A calculates the movement vector V 2 of the oncoming vehicle C from the movement history of the detection point P 2 (white circle) of the oncoming vehicle C. Further, the own vehicle A, the motion vector V 2 of the oncoming vehicle C, and calculates the expected movement locus T a of the oncoming vehicle C.

また、自車両Aは、図7に示すように、ガードレールを検出すると、これらガードレールの検出点P(白三角)に対する回避点Zを設定する。回避点Zは、検出点Pの各々について、自車両Aと当該検出点Pとを結ぶ直線上に設定される。 Further, as shown in FIG. 7, when the own vehicle A detects the guardrails, the own vehicle A sets an avoidance point Z for the detection point P 3 (white triangle) of these guardrails. Avoidance point Z, for each of the detection points P 3, it is set on a straight line connecting the own vehicle A and the detection point P 3.

回避点Zは、自車両がガードレールに極度に接近しないように余裕をもって回避できるように設定されることが好ましく、具体的には、例えば、a)一律に、自車両Aと検出点Pとを結ぶ直線の中点に設定されてもよく、或いは、b)自車両Aと検出点Pとの間の距離及び相対速度に応じて、距離が短いほど自車両A寄りに、及び/又は、相対速度が高いほど自車両A寄りに設定されるように演算によって求められてもよい。 The avoidance point Z is preferably set so that the own vehicle can be avoided with sufficient margin so as not to approach the guard rail extremely. Specifically, for example, a) the own vehicle A and the detection point P 3 are uniformly set. It may be set to the midpoint of a straight line connecting, or, b) depending on the distance and the relative velocity between the detection point P 3 between the vehicle a, the shorter the distance the vehicle a closer, and / or The higher the relative speed, the closer to the own vehicle A may be obtained by calculation.

次いで、自車両Aは、図8に示すように、対向車両Cの予想移動軌跡Tと重ならないように車線内側の仮想白線VLを引き、回避点Zより車線内側に車線外側の仮想白線VLを引く。 Then, the own vehicle A, as shown in FIG. 8, draw a virtual white VL lane inside so as not to overlap with the expected movement locus T a of the oncoming vehicle C, the virtual white line VL lane outside the lane inside the avoidance point Z pull.

さらに、本実施例において、この仮想白線VLは、一例として、図8に示すように、自車両から比較的近い近領域(例えば、自車両前方7〜17メートルの範囲)と、この近領域より奥側の遠領域(例えば、自車両前方17〜27メートルの範囲)とに分けてそれぞれ求められる。   Furthermore, in the present embodiment, the virtual white line VL is, as an example, as shown in FIG. 8, a near area relatively close to the own vehicle (for example, a range of 7 to 17 meters ahead of the own vehicle) and the near area. It is determined separately for the far region (for example, a range of 17 to 27 meters ahead of the host vehicle).

このようにして設定された仮想白線VLにより規定される車線が、推定された走行車線として目標車線に設定される。   The lane defined by the virtual white line VL set in this way is set as the target lane as the estimated travel lane.

図2に戻る。このようにして、検出された白線及び/又は設定された仮想白線によって制御目標車線が設定されると、次いで、制御部103は、物体検出部102によって白線上又は仮想白線上に障害物の存在が検出されたか否かを判断する(S207)。ここで、障害物とは、主として静止物であって、例えば駐車してある車両などである。   Returning to FIG. In this way, when the control target lane is set by the detected white line and / or the set virtual white line, then the control unit 103 causes the object detection unit 102 to have an obstacle on the white line or the virtual white line. Is detected (S207). Here, the obstacle is mainly a stationary object, for example, a parked vehicle.

白線上又は仮想白線上に障害物が検出された場合(S207の「YES」)、次いで、制御部103は、検出された障害物に対する回避点を演算する(S208)。   If an obstacle is detected on the white line or the virtual white line (“YES” in S207), the control unit 103 then calculates an avoidance point for the detected obstacle (S208).

そして、制御部103は、障害物に対して設定された回避点に基づいて仮想白線を描くことによって、目標車線を変更する(S209)。   And the control part 103 changes a target lane by drawing a virtual white line based on the avoidance point set with respect to the obstruction (S209).

このように障害物を回避するために目標車線を変更する場合の一例を図9〜11に示す。図9において、実線はガードレールや段差等の道路境界線を示し、白抜き太線Lは自車両Aが検出した白線又は設定した仮想白線位置を示している。   Examples of changing the target lane in order to avoid obstacles in this way are shown in FIGS. In FIG. 9, a solid line indicates a road boundary line such as a guardrail or a step, and a white white line L indicates a white line detected by the vehicle A or a set virtual white line position.

自車両Aは、図10に示すように、白線(又は仮想白線)上の障害物(ここでは、駐車車両D)を検出すると、駐車車両Dの検出点P(白丸)及びガードレールの検出点P(白三角)に対する回避点Zを設定する。回避点Zは、検出点P及びPの各々について、自車両Aと当該検出点とを結ぶ直線上に設定される。 As shown in FIG. 10, when the own vehicle A detects an obstacle (here, the parked vehicle D) on the white line (or virtual white line), the detection point P 2 (white circle) of the parked vehicle D and the detection point of the guardrail An avoidance point Z for P 3 (white triangle) is set. Avoidance point Z, for each of the detection points P 2 and P 3, are set on a straight line connecting the own vehicle A and the detection point.

回避点Zは、自車両が駐車車両Dに極度に接近しないように余裕をもって回避できるように設定されることが好ましく、具体的には、例えば、a)一律に、自車両Aと検出点Pとを結ぶ直線の中点に設定されてもよく、或いは、b)自車両Aと検出点Pとの間の距離及び相対速度に応じて、距離が短いほど自車両A寄りに、及び/又は、相対速度が高いほど自車両A寄りに設定されるように演算によって求められてもよい。 The avoidance point Z is preferably set so that the own vehicle can be avoided with sufficient margin so that the own vehicle does not extremely approach the parked vehicle D. Specifically, for example, a) the own vehicle A and the detection point P are uniformly set. 3 and may be set to the midpoint of a straight line connecting, or, b) depending on the distance and the relative velocity between the detection point P 3 between the vehicle a, the shorter the distance the vehicle a closer, and Alternatively, it may be obtained by calculation so that the higher the relative speed, the closer to the own vehicle A.

次いで、自車両Aは、図11に示すように、回避点Zより内側に車線外側の仮想白線VLを引く。   Next, as shown in FIG. 11, the host vehicle A draws a virtual white line VL outside the lane inside the avoidance point Z.

さらに、本実施例において、この仮想白線VLは、一例として、図11に示すように、自車両から比較的近い近領域(例えば、自車両前方7〜17メートルの範囲)と、この近領域より奥側の遠領域(例えば、自車両前方17〜27メートルの範囲)とに分けてそれぞれ求められる。   Furthermore, in this embodiment, the virtual white line VL is, as an example, as shown in FIG. 11, a near area relatively close to the own vehicle (for example, a range of 7 to 17 meters ahead of the own vehicle) and the near area. It is determined separately for the far region (for example, a range of 17 to 27 meters ahead of the host vehicle).

このようにして設定された仮想白線VLにより規定される車線が、新たな走行車線として目標車線に設定される。   The lane defined by the virtual white line VL set in this way is set as the new lane as the target lane.

図2に戻る。以上のように、白線が検出されなかった場合であっても先行車両や対向車両などから推定され、更には、必要に応じて、車線を維持していれば障害物を回避できるように適宜変更された目標車線について、以下のS210〜S213においては、従来通りの車線逸脱警報処理及び車線維持制御処理が行われる。   Returning to FIG. As described above, even if a white line is not detected, it is estimated from the preceding vehicle or oncoming vehicle, etc., and if necessary, appropriately changed so that obstacles can be avoided if the lane is maintained In the following S210 to S213, the conventional lane departure warning process and the lane maintenance control process are performed for the target lane that has been performed.

まず、制御部103は、自車両が目標車線から逸脱したか否かを判断する(S210)。逸脱した場合(S210の「YES」)、制御部103は警報部104へ指示して、車両乗員に注意喚起のための警報を発声させる(S211)。   First, the control unit 103 determines whether or not the host vehicle has deviated from the target lane (S210). When deviating ("YES" in S210), the control unit 103 instructs the alarm unit 104 to cause the vehicle occupant to issue an alarm for alerting (S211).

次いで、制御部103は、自車両が車線維持制御中であるか否かを判断する(S212)。車線維持制御中である場合(S212の「YES」)、制御部103は操舵制御部105へ指示して、自車両Aを目標車線の略中央を走行させるのに必要な操舵トルクを必要な操舵方向へ付与させる(S213)。   Next, the control unit 103 determines whether or not the host vehicle is in lane keeping control (S212). When the lane keeping control is being performed (“YES” in S212), the control unit 103 instructs the steering control unit 105 to perform a steering operation that requires the steering torque necessary to drive the host vehicle A substantially in the center of the target lane. The direction is given (S213).

このように、本実施例によれば、車線維持制御や車線逸脱警報などの車線に基づく運転支援を行う際に、何らかの理由により白線が検出できない場合であっても、仮想白線を設定することによって車線に基づく運転支援の継続を可能とすることができる。   Thus, according to the present embodiment, when performing driving support based on lanes such as lane keeping control and lane departure warning, even if a white line cannot be detected for some reason, by setting a virtual white line Driving assistance based on lanes can be continued.

また、本実施例によれば、走行車線に駐車車両などの障害物が存在する場合に、この障害物を回避するように仮想白線が設定されるため、車線に基づく運転支援を継続しながら障害物を回避することが可能となる。換言すれば、車線に基づく運転支援を継続するだけで、障害物回避が実現される。   In addition, according to the present embodiment, when there is an obstacle such as a parked vehicle in the traveling lane, the virtual white line is set so as to avoid the obstacle. Things can be avoided. In other words, obstacle avoidance is realized simply by continuing driving support based on the lane.

さらに、本実施例によれば、白線が検出されず、且つ、回避すべき障害物等も検出されない場合であっても、先行車両や対向車両などから自車両の走行車線を推定することができるため、車線に基づく運転支援を継続することができる。   Furthermore, according to the present embodiment, even when a white line is not detected and an obstacle or the like to be avoided is not detected, the traveling lane of the own vehicle can be estimated from the preceding vehicle or the oncoming vehicle. Therefore, driving support based on the lane can be continued.

なお、上記一実施例の説明においては、便宜上、(ア)先行車両を利用して仮想白線を描く場合(図3〜5)、(イ)対向車両等を利用して仮想白線を描く場合(図6〜8)、及び、(ウ)障害物を回避するように仮想白線を描く(又は修正する)場合(図9〜11)、に分けて説明したが、当業者には明らかなように、これらの仮想白線設定処理は必ずしも別々に順序立てて実行する必要はなく、先行車両、対向車両、ガードレール、及び、障害物などの自車両周辺の移動体及び静止物のすべてを同時に且つ総合的に考慮して一度の演算処理で仮想白線が設定されてもよい。   In the description of the above embodiment, for convenience, (a) a virtual white line is drawn using a preceding vehicle (FIGS. 3 to 5), and (a) a virtual white line is drawn using an oncoming vehicle ( 6 to 8) and (c) a case where a virtual white line is drawn (or corrected) so as to avoid an obstacle (FIGS. 9 to 11). These virtual white line setting processes do not necessarily have to be executed separately in order, and all of the moving objects and stationary objects around the host vehicle such as the preceding vehicle, the oncoming vehicle, the guardrail, and the obstacle are simultaneously and comprehensively processed. In consideration of the above, the virtual white line may be set by a single calculation process.

また、上記一実施例においては、仮想白線設定に利用する移動体の例として、特に図面において四輪車を挙げたが、本発明はこれに限定されるものではなく、自動二輪車や自転車や歩行者なども利用し得る。   Further, in the above-described embodiment, as an example of the moving body used for the virtual white line setting, a four-wheeled vehicle is specifically shown in the drawings. However, the present invention is not limited to this, and a motorcycle, a bicycle or a walking is used. Can also be used.

さらに、上記一実施例においては、回避すべき障害物の一例として駐車車両を例に挙げたが、本発明はこれに限定されるものではなく、自車両走行車線上で静止しており、自車両の白線に基づく車両制御に影響を与え得るものであればあらゆる静止物体を対象とし得る。   Furthermore, in the above-described embodiment, a parked vehicle is taken as an example of an obstacle to be avoided. However, the present invention is not limited to this, and the vehicle is stationary on the own vehicle travel lane. Any stationary object that can affect vehicle control based on the white line of the vehicle can be targeted.

本発明は、レーンキープアシスト装置やレーンデパーチャワーニング装置などの車両用運転支援装置に利用できる。搭載される車両の外観、重量、サイズ、走行性能等は問わない。   The present invention can be used for a vehicle driving support device such as a lane keep assist device and a lane departure warning device. The appearance, weight, size, running performance, etc. of the vehicle to be mounted are not limited.
