Description

本発明は、車両用ドアミラー装置に係り、特に、車両の後退駐車操作を支援するための車両用ドアミラー装置に関する。   The present invention relates to a vehicle door mirror device, and more particularly to a vehicle door mirror device for supporting a reverse parking operation of a vehicle.

従来より、車両後方の視界を確保するために、車両の後方に向けられる反射鏡を有する車両用ドアミラー装置が用いられている。特に、近年では、車両の駐車操作を支援するために、車両の駐車操作をガイドするためのガイド表示をドアミラーの鏡面に表示するドアミラー装置として、例えば、特許文献1には、ドアミラーの鏡面に、運転操作の起点となる目標物が映り込む位置を示すガイド表示を設けた車両後退時の運転操作支援システムが開示されている。   Conventionally, in order to secure a field of view behind the vehicle, a vehicle door mirror device having a reflecting mirror directed toward the rear of the vehicle has been used. In particular, in recent years, as a door mirror device that displays a guide display for guiding the parking operation of the vehicle on the mirror surface of the door mirror in order to assist the parking operation of the vehicle, for example, Patent Document 1 discloses a mirror surface of the door mirror, There is disclosed a driving operation support system at the time of reverse of a vehicle provided with a guide display indicating a position where a target object as a starting point of driving operation is reflected.

この特許文献1の運転操作支援システムでは、例えば、後退駐車(車庫入れ駐車)を行う場合、まず、ドアミラーの鏡面に表示されたすえ切り開始ガイドラインとミラーに映る駐車スペースの区画線とが一致する位置まで車両を後退させ、次に、車両を停止させ、その停止状態でステアリングホイールを駐車スペース方向にすえ切りし、その後、車両を後退させるようにしている。   In the driving operation support system of this Patent Document 1, for example, when performing reverse parking (garage parking), first, the guideline for start-up displayed on the mirror surface of the door mirror matches the partition line of the parking space reflected in the mirror. The vehicle is moved backward to the position, then the vehicle is stopped, and in the stopped state, the steering wheel is turned in the parking space direction, and then the vehicle is moved backward.

ところで、実際には、車両の駐車操作においては、駐車枠の前方で車両を前進、後退、転回等させることが可能なスペースの大きさや、隣の駐車枠に駐車している隣接駐車車両の位置等の周辺状況に応じて、駐車操作を開始するときの車両の位置や姿勢、あるいは後退時の車両の回転半径を調節することが必要になる。
したがって、上述したような周辺状況に応じて、駐車操作開始時の車両の位置や姿勢、あるいは後退時の車両の回転半径を調節することができるように、ドライバのステアリング操作の自由度が残されていることが好ましい。また、ステアリング操作の自由度が残されていることにより、駐車が完了したときにドライバが自らの操作によって駐車を成功させたという満足感を得ることが可能になる。

Therefore, the degree of freedom of the steering operation of the driver remains so that the position and posture of the vehicle at the start of the parking operation or the turning radius of the vehicle at the time of reverse can be adjusted according to the surrounding situation as described above. It is preferable. In addition, since the degree of freedom of the steering operation is left, it is possible to obtain a satisfaction that the driver has succeeded in parking by own operation when parking is completed.

しかしながら、上述した特許文献1の運転操作支援システムでは、駐車操作開始時の車両の位置や姿勢、及び後退時の車両の回転半径が固定されているので、駐車時の周辺状況によっては、運転操作支援システムのガイドに従うだけでは駐車操作を完了できないという問題がある。また、運転操作支援システムのガイドに従って駐車操作を完了させることができたとしても、自らの操作によって駐車を成功させたという満足感を十分に得ることができないという問題がある。   However, in the driving support system of Patent Document 1 described above, the position and posture of the vehicle at the start of the parking operation and the turning radius of the vehicle at the time of reversing are fixed. There is a problem that the parking operation cannot be completed only by following the guide of the support system. In addition, even if the parking operation can be completed according to the guide of the driving operation support system, there is a problem that it is not possible to obtain a satisfactory feeling that the parking operation has been successful by the user's own operation.

FIG. 3 is a plan view showing the vehicle 1 when the center of the rear wheel axis intersects the front edge of the parking frame on the locus of reversing parking in the parking frame while turning at a minimum turning radius in advance for determining the position of the marker. It is. In the following description, the position and posture of the vehicle 1 when the center of the rear wheel axis intersects the front edge of the parking frame on the trajectory of reversing parking in the parking frame while turning at the minimum turning radius is referred to as “parking frame approaching posture”. Shall.

まず、図1に示すように、車両1の中心線Cと反射鏡8との車幅方向距離をLxとし、車両1の後輪軸線Sと反射鏡8との前後方向距離をLyとする。   First, as shown in FIG. 1, the distance in the vehicle width direction between the center line C of the vehicle 1 and the reflecting mirror 8 is Lx, and the distance in the front-rear direction between the rear wheel axis S of the vehicle 1 and the reflecting mirror 8 is Ly.

次に、図2に示すように、反射鏡8の車幅方向外側端と第1のマーカ10との幅方向距離をLmとし、第1のマーカ10と第2のマーカ12との幅方向距離をLMとする。Lmは、例えば、反射鏡8の車幅方向内側端と車幅方向外側端との水平距離の5分の4の長さである。   Next, as shown in FIG. 2, the distance in the width direction between the outer end in the vehicle width direction of the reflecting mirror 8 and the first marker 10 is Lm, and the distance in the width direction between the first marker 10 and the second marker 12. Is LM. Lm is, for example, the length of 4/5 of the horizontal distance between the inner end in the vehicle width direction and the outer end in the vehicle width direction of the reflecting mirror 8.

次に、図3に示すように、車両1の最小回転半径をRc、駐車枠進入姿勢における車両1の前後方向と駐車枠16の前後方向とが成す角度をθv、最小回転半径で旋回しながら駐車枠16に進入した車両1の前後方向と駐車枠16の前後方向とが平行になった場合(すなわち、車両1の旋回が完了した場合)の車両1の後輪軸と駐車枠16の先端との距離をLbとする。
また、駐車枠16の前縁中央を原点とした直交座標系において、車両1の反射鏡8の座標を(Xm,Ym)、隣接車両18の自車両1に近い側の前端角部分(図3では右前角部分)の座標を(Xs,Ys)、駐車枠進入姿勢における車両1の後輪軸中心と駐車枠16の前縁との交点の座標を(Xr,0)とする。
さらに、ドライバから見て、反射鏡8の車幅方向外側端と第1のマーカ10との間の画角をθm、駐車枠進入姿勢において隣接車両18の前端角部分が反射鏡8に映る位置と第1のマーカ10との間の画角をθMとする。
Next, as shown in FIG. 3, the minimum turning radius of the vehicle 1 is Rc, the angle formed by the longitudinal direction of the vehicle 1 and the longitudinal direction of the parking frame 16 in the parking frame approaching posture is θv, When the front and rear direction of the vehicle 1 that has entered the parking frame 16 and the front and rear direction of the parking frame 16 are parallel (that is, when the turning of the vehicle 1 is completed), the rear axle of the vehicle 1 and the front end of the parking frame 16 Is the distance Lb.
Further, in the Cartesian coordinate system with the center of the front edge of the parking frame 16 as the origin, the coordinates of the reflecting mirror 8 of the vehicle 1 are (Xm, Ym), and the front end corner portion of the adjacent vehicle 18 closer to the host vehicle 1 (FIG. 3). Let (Xs, Ys) be the coordinates of the right front corner portion), and (Xr, 0) be the coordinates of the intersection of the rear wheel axle center of the vehicle 1 and the front edge of the parking frame 16 in the parking frame approach posture.
Further, when viewed from the driver, the angle of view between the outer end in the vehicle width direction of the reflecting mirror 8 and the first marker 10 is θm, and the front end corner portion of the adjacent vehicle 18 is reflected on the reflecting mirror 8 in the parking frame approaching posture. And the angle of view between the first marker 10 and θM.

上述した各パラメータの内、Lx、Ly、及び、Rcは、車両1の仕様により定まる定数である。また、Lbは、車両1の最小回転半径Rcと駐車枠16の幅(例えば、2.5m)に基づいて設定された定数であり、1〜1.5mである。また、隣接車両18の前端角部分の座標(Xs,Ys)は、駐車枠16の寸法や一般的な車両寸法に基づいて設定された定数である。例えば、駐車枠16の幅が2.5mであり、隣接車両18の前端角部分と駐車枠16の前縁及び側縁との距離がそれぞれ0.3mである場合、隣接車両18の前端角部分の座標(Xs,Ys)は(−1.55m,−0.3m)である。   Among the parameters described above, Lx, Ly, and Rc are constants determined by the specifications of the vehicle 1. Lb is a constant set based on the minimum turning radius Rc of the vehicle 1 and the width of the parking frame 16 (for example, 2.5 m), and is 1 to 1.5 m. Further, the coordinates (Xs, Ys) of the front end corner portion of the adjacent vehicle 18 are constants set based on the dimensions of the parking frame 16 and general vehicle dimensions. For example, when the width of the parking frame 16 is 2.5 m, and the distance between the front end corner portion of the adjacent vehicle 18 and the front edge and side edge of the parking frame 16 is 0.3 m, the front end corner portion of the adjacent vehicle 18. The coordinates (Xs, Ys) are (−1.55 m, −0.3 m).

第1のマーカ10と第2のマーカ12との幅方向距離LMと、反射鏡8の車幅方向外側端と第1のマーカ10との幅方向距離Lmとの比は、駐車枠進入姿勢において隣接車両18の前端角部分が反射鏡8に映る位置と第1のマーカ10との間の画角θMと、反射鏡8の車幅方向外側端と第1のマーカ10との間の画角θmとの比に等しい。
すなわち、第1のマーカ10と第2のマーカ12との幅方向距離LMは、駐車枠進入姿勢において隣接車両18の前端角部分が反射鏡8に映る位置と第1のマーカ10との間の画角θM、反射鏡8の車幅方向外側端と第1のマーカ10との間の画角θm、及び、反射鏡8の車幅方向外側端と第1のマーカ10との幅方向距離Lmにより、次式のように表される。

FIG. 4 is a plan view showing the vehicle 1 when the front-rear direction of the vehicle 1 that has entered the parking frame 16 in advance and the front-rear direction of the parking frame 16 are parallel to determine the position of the marker.

まず、図2に示すように、第1のマーカ10と第3のマーカ14との幅方向距離をLPとする。   First, as shown in FIG. 2, the distance in the width direction between the first marker 10 and the third marker 14 is LP.

次に、図4に示すように、駐車枠16に進入した車両1の前後方向と駐車枠16の前後方向とが平行になった場合(すなわち、車両1の旋回が完了した場合)の車両1の後輪軸と駐車枠16の先端との距離は、図3を参照して説明したように、Lbである。すなわち、この場合の車両1の後輪軸中心の座標は、(0,−Lb)である。
また、駐車枠16の前縁中央を原点とした直交座標系において、駐車枠16の角部分(図4では右前角部分)の座標を(Xp,0)とする。

Next, as shown in FIG. 4, the vehicle 1 when the front-rear direction of the vehicle 1 that has entered the parking frame 16 and the front-rear direction of the parking frame 16 are parallel (that is, when the turning of the vehicle 1 is completed). The distance between the rear wheel axle and the tip of the parking frame 16 is Lb as described with reference to FIG. That is, the coordinates of the center of the rear wheel axis of the vehicle 1 in this case are (0, -Lb).
In the orthogonal coordinate system with the center of the front edge of the parking frame 16 as the origin, the coordinates of the corner portion of the parking frame 16 (the right front corner portion in FIG. 4) are (Xp, 0).
Further, when viewed from the driver, the angle of view between the outer end in the vehicle width direction of the reflecting mirror 8 and the first marker 10 is θm, the front-rear direction of the vehicle 1 that has entered the parking frame 16, and the front-rear direction of the parking frame 16 Is the angle of view between the position where the corner portion of the parking frame 16 is reflected on the reflecting mirror 8 and the first marker 10 on the inner side of the turning of the vehicle 1 (left side of the vehicle 1 in FIG. 4). To do.

上述した各パラメータの内、駐車枠16の角部分の座標(Xp,0)は、駐車枠16の寸法に基づいて設定された定数である。例えば、駐車枠16の幅が2.5mである場合、駐車枠16の角部分の座標(Xp,0)は(−1.25m,0m)である。   Among the parameters described above, the coordinates (Xp, 0) of the corner portion of the parking frame 16 are constants set based on the dimensions of the parking frame 16. For example, when the width of the parking frame 16 is 2.5 m, the coordinates (Xp, 0) of the corner portion of the parking frame 16 are (−1.25 m, 0 m).

第1のマーカ10と第3のマーカ14との幅方向距離LPと、反射鏡8の車幅方向外側端と第1のマーカ10との幅方向距離Lmとの比は、駐車枠16に進入した車両1の前後方向と駐車枠16の前後方向とが平行になった場合の車両1の旋回内側における駐車枠16の角部分が反射鏡8に映る位置と第1のマーカ10との間の画角θPと、反射鏡8の車幅方向外側端と第1のマーカ10との間の画角θmとの比に等しい。

The ratio between the width direction distance LP between the first marker 10 and the third marker 14 and the width direction distance Lm between the outer end in the vehicle width direction of the reflecting mirror 8 and the first marker 10 enters the parking frame 16. Between the position where the corner portion of the parking frame 16 is reflected on the reflecting mirror 8 and the first marker 10 when the vehicle 1 and the parking frame 16 are parallel to each other. This is equal to the ratio of the angle of view θP and the angle of view θm between the outer end of the reflecting mirror 8 in the vehicle width direction and the first marker 10.
That is, the width direction distance LP between the first marker 10 and the third marker 14 is that of the vehicle 1 when the longitudinal direction of the vehicle 1 entering the parking frame 16 and the longitudinal direction of the parking frame 16 are parallel to each other. The angle of view θP between the position where the corner portion of the parking frame 16 is reflected on the reflecting mirror 8 and the first marker 10 on the inside of the turn, and the image between the outer end in the vehicle width direction of the reflecting mirror 8 and the first marker 10. The angle θm and the width direction distance Lm between the outer end of the reflecting mirror 8 in the vehicle width direction and the first marker 10 are expressed as follows.
Figure 0006191815

この式(13)におけるθPは、図4に示すように、反射鏡8の座標(Xm,Ym)と駐車枠16の角部分の座標(Xp,0)を結ぶ直線と、駐車枠16の前後方向とが成す角度である。すなわち、角度θPは、座標(Xm,Ym)と座標(Xp,0)により、次式のように表される。

Figure 0006191815
As shown in FIG. 4, θP in this equation (13) is a straight line connecting the coordinates (Xm, Ym) of the reflecting mirror 8 and the coordinates (Xp, 0) of the corner portion of the parking frame 16 and the front and rear of the parking frame 16. The angle formed by the direction. That is, the angle θP is expressed by the following equation by the coordinates (Xm, Ym) and the coordinates (Xp, 0).
Figure 0006191815

そして、式(14)におけるXmは、図1及び図4に示すように、車幅方向における車両1の中心と反射鏡8との距離Lxを用いて次式のように表される。

Figure 0006191815
Xm in the equation (14) is expressed by the following equation using the distance Lx between the center of the vehicle 1 and the reflecting mirror 8 in the vehicle width direction, as shown in FIGS.
Figure 0006191815

また、式(14)におけるYmは、図1及び図4に示すように、駐車枠16に進入した車両1の前後方向と駐車枠16の前後方向とが平行になった場合の車両1の後輪軸中心のy座標(−Lb)、及び、車両1の前後方向における車両1の後輪軸と反射鏡8との距離Lyを用いて、次式のように表される。

Figure 0006191815
Further, Ym in the equation (14) is the rear of the vehicle 1 when the front-rear direction of the vehicle 1 that has entered the parking frame 16 and the front-rear direction of the parking frame 16 are parallel, as shown in FIGS. Using the y coordinate (−Lb) of the center of the wheel axis and the distance Ly between the rear wheel shaft of the vehicle 1 and the reflecting mirror 8 in the front-rear direction of the vehicle 1, the following expression is used.
Figure 0006191815

上述した式(13)に、上述した式(14)乃至(16)を代入することにより、第1のマーカ10と第3のマーカ14との幅方向距離LPは、定数Lm、Lx、Ly、Lb、及び、Xpを用いて算出される。   By substituting the above-described equations (14) to (16) into the above-described equation (13), the width direction distance LP between the first marker 10 and the third marker 14 is a constant Lm, Lx, Ly, Calculated using Lb and Xp.

次に、図5により、本発明の実施形態による車両用ドアミラー装置の作用を説明する。図5は、本発明の実施形態による車両用ドアミラー装置を有する車両1が旋回しながら駐車枠16に後退駐車するときの軌跡を示す平面図であり、(a)は駐車枠16から離れる方向に車両1を旋回させた後に駐車枠16に向かって車両1を後退させる場合の軌跡を示す図、(b)は駐車枠16の前方を通過した後に駐車枠16に向かって車両1を後退させる場合の軌跡を示す図である。
この図5において、ドアミラー装置6の反射鏡8から左側後方に延びる点線は、反射鏡8の車幅方向外側端と第1のマーカ10との間の画角を示す。また、反射鏡8から左側後方に延びる一点鎖線は、反射鏡8の第2のマーカ12と第1のマーカ10との間の画角を示す。
Next, the operation of the vehicle door mirror device according to the embodiment of the present invention will be described with reference to FIG. FIG. 5 is a plan view showing a trajectory when the vehicle 1 having the vehicle door mirror device according to the embodiment of the present invention parks backward in the parking frame 16 while turning, and (a) is in a direction away from the parking frame 16. The figure which shows the locus | trajectory at the time of moving the vehicle 1 back toward the parking frame 16 after turning the vehicle 1, (b) is the case where the vehicle 1 is moved back toward the parking frame 16 after passing the front of the parking frame 16. It is a figure which shows the locus | trajectory.
In FIG. 5, a dotted line extending rearward on the left side from the reflecting mirror 8 of the door mirror device 6 indicates an angle of view between the outer end in the vehicle width direction of the reflecting mirror 8 and the first marker 10. A one-dot chain line extending rearward from the reflecting mirror 8 indicates the angle of view between the second marker 12 and the first marker 10 of the reflecting mirror 8.

まず、図5(a)に示すように、駐車枠16から離れる方向に車両1を旋回(図5(a)では右旋回)させた後に駐車枠16に向かって車両1を後退させる場合、ドライバが、隣接車両18の前端角部分が常に第2のマーカ12の位置で反射鏡8に映るようにステアリング操作を行うことにより、車両1は、図5(a)において反射鏡8から左側後方に延びる一点鎖線が常に隣接車両18の右前端角部分と接するように旋回しながら後退する。   First, as shown in FIG. 5A, when turning the vehicle 1 in a direction away from the parking frame 16 (turning right in FIG. 5A) and then moving the vehicle 1 backward toward the parking frame 16, When the driver performs a steering operation so that the front end corner portion of the adjacent vehicle 18 is always reflected on the reflecting mirror 8 at the position of the second marker 12, the vehicle 1 is rearward on the left side from the reflecting mirror 8 in FIG. The vehicle moves backward while turning so that the alternate long and short dash line always contacts the right front end corner of the adjacent vehicle 18.

また、図5(b)に示すように、駐車枠16の前方を通過した後に駐車枠16に向かって車両1を後退させる場合においても、ドライバが、隣接車両18の前端角部分が常に第2のマーカ12の位置で反射鏡8に映るようにステアリング操作を行うことにより、車両1は、図5(a)において反射鏡8から左側後方に延びる一点鎖線が常に隣接車両18の右前端角部分と接するように旋回しながら後退する。   Further, as shown in FIG. 5B, even when the vehicle 1 is moved backward toward the parking frame 16 after passing the front of the parking frame 16, the driver always keeps the front end corner portion of the adjacent vehicle 18 in the second position. By performing the steering operation so as to be reflected on the reflecting mirror 8 at the position of the marker 12, the vehicle 1 always has a one-dot chain line extending leftward and rearward from the reflecting mirror 8 in FIG. Retreat while turning to contact with.

このように、隣接車両18の前端角部分が常に第2のマーカ12の位置で反射鏡8に映るようにステアリング操作を行うことにより、図5(a)及び図5(b)のいずれの場合においても、車両1は駐車枠16の中央近傍に向かって後退する。
すなわち、ドライバが反射鏡8を見たとき、隣接車両18の前端角部分が第2のマーカ12よりも車幅方向内側に映っている場合には、車両1の回転半径が大きくなるように、すなわち、操舵角が小さくなるようにステアリング操作を行い、隣接車両18の前端角部分が第2のマーカ12よりも車幅方向外側に映っている場合には、車両1の回転半径が小さくなるように、すなわち、操舵角が大きくなるようにステアリング操作を行うと、車両1を駐車枠16の中央近傍に向かって後退させるための適当な回転半径が維持される。これにより、車両1は、後輪軸中心が駐車枠16の前縁と交差するときにその前縁の中央近傍に位置するように後退する。
As described above, by performing the steering operation so that the front end corner portion of the adjacent vehicle 18 is always reflected on the reflecting mirror 8 at the position of the second marker 12, either of FIG. 5A and FIG. 5B. The vehicle 1 also moves backward toward the center of the parking frame 16.
That is, when the driver looks at the reflecting mirror 8, when the front end corner portion of the adjacent vehicle 18 is reflected on the inner side in the vehicle width direction than the second marker 12, the turning radius of the vehicle 1 is increased. That is, when the steering operation is performed so that the steering angle becomes small and the front end corner portion of the adjacent vehicle 18 is reflected outside the second marker 12 in the vehicle width direction, the turning radius of the vehicle 1 becomes small. In other words, when the steering operation is performed so that the steering angle becomes large, an appropriate turning radius for moving the vehicle 1 backward toward the center of the parking frame 16 is maintained. As a result, the vehicle 1 moves backward so that the rear wheel axle center is located in the vicinity of the center of the front edge when it intersects the front edge of the parking frame 16.

また、自車両1が駐車する駐車枠16の隣に他の車両が駐車していない場合には、駐車枠16に向かって車両1を旋回させながら後退させる際、ドライバが、旋回内側にある駐車枠16の角部分が常に第3のマーカ14の位置で反射鏡8に映るようにステアリング操作を行うことにより、車両1は駐車枠16の中央近傍に向かって後退する。   In addition, when another vehicle is not parked next to the parking frame 16 where the host vehicle 1 is parked, when the vehicle 1 is moved backward while turning toward the parking frame 16, the driver is parked inside the turn. By performing the steering operation so that the corner portion of the frame 16 is always reflected on the reflecting mirror 8 at the position of the third marker 14, the vehicle 1 moves backward toward the center of the parking frame 16.

次に、本発明の実施形態のさらなる変形例を説明する。
上述した実施形態においては、第3のマーカ14は、反射鏡8が、ドライバから見て第1のマーカ10が反射鏡8に映る自車両1の側面と一致するように予め調整され、且つ、予め最小回転半径で旋回しながら駐車枠16に進入した車両1の前後方向と駐車枠16の前後方向とが平行になった場合に、車両1の旋回内側における駐車枠16の角部分が反射鏡8に映るような位置に規定されているが、これとは異なるように第3のマーカ14を規定してもよい。
Next, further modifications of the embodiment of the present invention will be described.
In the above-described embodiment, the third marker 14 is adjusted in advance so that the reflecting mirror 8 coincides with the side surface of the host vehicle 1 in which the first marker 10 is reflected on the reflecting mirror 8 when viewed from the driver, and When the front-rear direction of the vehicle 1 entering the parking frame 16 while turning at a minimum turning radius in advance is parallel to the front-rear direction of the parking frame 16, the corner portion of the parking frame 16 inside the turn of the vehicle 1 is a reflecting mirror. However, the third marker 14 may be defined differently.

例えば、第3のマーカ14は、反射鏡8が、ドライバから見て第1のマーカ10が反射鏡8に映る自車両1の側面と一致するように予め調整され、且つ、予め車両1が最小回転半径で旋回しながら駐車枠16に後退駐車する軌跡上で後輪軸中心が駐車枠16の前縁と交差した場合(駐車枠進入姿勢)に、車両1の旋回内側における駐車枠16の角部分が反射鏡8に映るような位置に規定されてもよい。   For example, the third marker 14 is adjusted in advance so that the reflecting mirror 8 matches the side surface of the host vehicle 1 viewed from the driver and the first marker 10 is reflected on the reflecting mirror 8, and the vehicle 1 is minimized. The corner portion of the parking frame 16 inside the turning of the vehicle 1 when the center of the rear wheel axis intersects the front edge of the parking frame 16 on the locus of reversing parking in the parking frame 16 while turning at the turning radius (parking frame approaching posture). May be defined at a position such that is reflected on the reflecting mirror 8.

この場合、第1のマーカ10と第3のマーカ14との幅方向距離LPは、駐車枠進入姿勢において駐車枠16の角部分が反射鏡8に映る位置と第1のマーカ10との間の画角θP、反射鏡8の車幅方向外側端と第1のマーカ10との間の画角θm、及び、反射鏡8の車幅方向外側端と第1のマーカ10との幅方向距離Lmにより、次式のように表される。

Figure 0006191815
In this case, the width direction distance LP between the first marker 10 and the third marker 14 is between the position where the corner portion of the parking frame 16 is reflected on the reflecting mirror 8 and the first marker 10 in the parking frame approaching posture. The angle of view θP, the angle of view θm between the outer end in the vehicle width direction of the reflecting mirror 8 and the first marker 10, and the width direction distance Lm between the outer end of the reflecting mirror 8 in the vehicle width direction and the first marker 10. Is expressed as the following equation.
Figure 0006191815

この式(17)におけるθPは、駐車枠進入姿勢における車両1の前後方向と駐車枠16の前後方向とが成す角度θv、反射鏡8の座標(Xm,Ym)、及び、駐車枠16の角部分の座標(Xp,0)により、次式のように表される。

Figure 0006191815
ΘP in this equation (17) is an angle θv formed by the front-rear direction of the vehicle 1 and the front-rear direction of the parking frame 16 in the parking frame approaching posture, the coordinates (Xm, Ym) of the reflecting mirror 8, and the angle of the parking frame 16 By the coordinates (Xp, 0) of the part, it is expressed as the following equation.
Figure 0006191815

そして、この式(18)におけるθv、Xm及びYmは、上述した実施形態と同様に、式(9)乃至(12)により表される。すなわち、上述した式(17)に、式(18)及び式(9)乃至(12)を代入することにより、第1のマーカ10と第3のマーカ14との幅方向距離LPは、定数Lm、Lx、Ly、Rc、Lb、及び、Xpを用いて算出される。   Then, θv, Xm, and Ym in the equation (18) are represented by the equations (9) to (12) as in the above-described embodiment. That is, by substituting Equation (18) and Equations (9) to (12) into Equation (17) described above, the distance in the width direction LP between the first marker 10 and the third marker 14 is a constant Lm. , Lx, Ly, Rc, Lb, and Xp.

次に、上述した本発明の実施形態及び本発明の実施形態の変形例による車両用ドアミラー装置の効果を説明する。   Next, effects of the above-described embodiment of the present invention and the vehicle door mirror device according to the modification of the embodiment of the present invention will be described.

まず、第2のマーカ12は、反射鏡8が、ドライバから見て第1のマーカ10が反射鏡8に映る自車両1の側面と一致するように予め調整され、且つ、予め車両1が最小回転半径で旋回しながら駐車枠16に後退駐車する軌跡上で後輪軸中心が駐車枠16の前縁と交差した場合に、車両1の旋回内側において駐車枠16の隣に駐車している隣接車両18の前端角部分が反射鏡8に映るような位置に規定されているので、ドライバは、車両1の後退駐車操作を行うときに、反射鏡8を、ドライバから見て第1のマーカ10が反射鏡8に映る自車両1の側面と一致するように予め調整し、且つ、隣接車両18の前端角部分が常に第2のマーカ12の位置で反射鏡8に映るようにステアリング操作を行うことにより、駐車操作開始時の車両1の位置や姿勢に関わらず、後輪軸中心が駐車枠16の前縁と交差するときにその前縁の中央近傍に位置するように車両1を最小回転半径以上の適切な回転半径で旋回しながら後退させることができ、車両1を駐車枠16の中央近傍に駐車させることができる。したがって、ドライバのステアリング操作の自由度を残すことができる。これにより、ドライバは、駐車操作の完了時に自らの操作によって駐車を成功させたという満足感を得ることができる。   First, the second marker 12 is adjusted in advance so that the reflecting mirror 8 coincides with the side surface of the host vehicle 1 in which the first marker 10 is reflected on the reflecting mirror 8 when viewed from the driver, and the vehicle 1 is minimized. An adjacent vehicle parked next to the parking frame 16 inside the turn of the vehicle 1 when the center of the rear wheel axis intersects the front edge of the parking frame 16 on the trajectory of reversing parking in the parking frame 16 while turning at the turning radius Since the front end angle portion of 18 is defined at a position where it is reflected on the reflecting mirror 8, when the driver performs the backward parking operation of the vehicle 1, the first marker 10 is seen when viewing the reflecting mirror 8 from the driver. A steering operation is performed so that the front end corner portion of the adjacent vehicle 18 is always reflected on the reflecting mirror 8 at the position of the second marker 12 so as to coincide with the side surface of the own vehicle 1 reflected on the reflecting mirror 8. By the position of the vehicle 1 at the time of parking operation start Regardless of the posture, the vehicle 1 is moved backward while turning at an appropriate turning radius equal to or larger than the minimum turning radius so that the center of the rear wheel shaft intersects with the front edge of the parking frame 16 and is located near the center of the front edge. The vehicle 1 can be parked near the center of the parking frame 16. Therefore, the degree of freedom of the driver's steering operation can be left. Thereby, the driver can obtain the satisfaction that the parking has been successful by his own operation when the parking operation is completed.

また、第3のマーカ14は、反射鏡8が、ドライバから見て第1のマーカ10が反射鏡8に映る自車両1の側面と一致するように予め調整され、且つ、予め最小回転半径で旋回しながら駐車枠16に進入した車両1の前後方向と駐車枠16の前後方向とが平行になった場合に、車両1の旋回内側における駐車枠16の角部分が反射鏡8に映るような位置に規定されているので、ドライバは、車両1の後退駐車操作を行うときに、反射鏡8を、ドライバから見て第1のマーカ10が反射鏡8に映る自車両1の側面と一致するように予め調整し、且つ、旋回内側にある駐車枠16の角部分が常に第3のマーカ14の位置で反射鏡8に映るようにステアリング操作を行うことにより、例えば隣接車両が存在してもしなくても、駐車操作開始時の車両1の位置や姿勢に関わらず、駐車枠16に進入した車両1の前後方向と駐車枠16の前後方向とが平行になったときに駐車枠16の中央近傍に位置するように、車両1を最小回転半径以上の適切な回転半径で旋回しながら後退させることができる。したがって、ドライバのステアリング操作の自由度を残すことができる。   The third marker 14 is adjusted in advance so that the reflecting mirror 8 coincides with the side surface of the host vehicle 1 when the first marker 10 is reflected on the reflecting mirror 8 when viewed from the driver, and the third marker 14 has a minimum turning radius in advance. When the front-rear direction of the vehicle 1 entering the parking frame 16 while turning and the front-rear direction of the parking frame 16 are parallel, the corner portion of the parking frame 16 on the inner side of the turn of the vehicle 1 is reflected on the reflecting mirror 8. When the driver performs the backward parking operation of the vehicle 1, the driver matches the side surface of the host vehicle 1 in which the first marker 10 is reflected in the reflector 8 when the driver views the reflector 8. If the steering operation is performed so that the corner portion of the parking frame 16 on the inner side of the turn is always reflected on the reflecting mirror 8 at the position of the third marker 14, for example, an adjacent vehicle may exist. Even if there is no vehicle at the start of parking operation Regardless of the position and posture of the vehicle, the vehicle 1 is minimized so that it is positioned near the center of the parking frame 16 when the longitudinal direction of the vehicle 1 that has entered the parking frame 16 and the longitudinal direction of the parking frame 16 are parallel to each other. It is possible to move backward while turning at an appropriate turning radius equal to or greater than the turning radius. Therefore, the degree of freedom of the driver's steering operation can be left.

また、第2のマーカ12の位置は、上述した式(6)により規定されるので、車両1が最小回転半径で旋回しながら駐車枠16に後退駐車する軌跡上で後輪軸中心が駐車枠16の前縁と交差した場合の、隣接車両18の前端角部分が反射鏡8に映る位置に正確に第2のマーカ12を付すことができる。これにより、ドライバは、車両1の後退駐車操作を行うときに、反射鏡8を、ドライバから見て第1のマーカ10が反射鏡8に映る自車両1の側面と一致するように予め調整し、且つ、隣接車両18の前端角部分が常に第2のマーカ12の位置で反射鏡8に映るようにステアリング操作を行うことにより、駐車操作開始時の車両1の位置や姿勢に関わらず、後輪軸中心が駐車枠16の前縁と交差するときにその前縁の中央近傍に位置するように車両1を最小回転半径以上の適切な回転半径で旋回しながら後退させることができ、車両1を駐車枠16の中央近傍に確実に駐車させることができる。   Further, since the position of the second marker 12 is defined by the above-described formula (6), the center of the rear wheel axis is on the parking frame 16 on the trajectory where the vehicle 1 is parked backward on the parking frame 16 while turning at the minimum turning radius. The second marker 12 can be accurately attached to the position where the front end corner portion of the adjacent vehicle 18 is reflected on the reflecting mirror 8 when it intersects the front edge. As a result, when the driver performs the backward parking operation of the vehicle 1, the driver adjusts the reflecting mirror 8 in advance so that the first marker 10 coincides with the side surface of the host vehicle 1 reflected on the reflecting mirror 8 when viewed from the driver. In addition, by performing the steering operation so that the front end corner portion of the adjacent vehicle 18 is always reflected on the reflecting mirror 8 at the position of the second marker 12, the rear end of the vehicle 1 regardless of the position or posture of the vehicle 1 is started. The vehicle 1 can be moved backward while turning with an appropriate turning radius that is equal to or greater than the minimum turning radius so that the center of the axle intersects with the front edge of the parking frame 16 and is located near the center of the front edge. The parking frame 16 can be reliably parked near the center.

特に、第1のマーカ10と第2のマーカ12との幅方向距離(LM)は、上述した式(8)乃至(12)を用いて算出されるので、車両1が最小回転半径で旋回しながら駐車枠16に後退駐車する軌跡上で後輪軸中心が駐車枠16の前縁と交差した場合の、隣接車両18の前端角部分が反射鏡8に映る位置に正確に第2のマーカ12を付すことができる。これにより、ドライバは、車両1の後退駐車操作を行うときに、反射鏡8を、ドライバから見て第1のマーカ10が反射鏡8に映る自車両1の側面と一致するように予め調整し、且つ、隣接車両18の前端角部分が常に第2のマーカ12の位置で反射鏡8に映るようにステアリング操作を行うことにより、駐車操作開始時の車両1の位置や姿勢に関わらず、後輪軸中心が駐車枠16の前縁と交差するときにその前縁の中央近傍に位置するように車両1を最小回転半径以上の適切な回転半径で旋回しながら後退させることができ、車両1を駐車枠16の中央近傍に確実に駐車させることができる。   In particular, since the distance in the width direction (LM) between the first marker 10 and the second marker 12 is calculated using the above-described equations (8) to (12), the vehicle 1 turns with the minimum turning radius. However, the second marker 12 is accurately positioned at the position where the front end corner portion of the adjacent vehicle 18 is reflected in the reflecting mirror 8 when the center of the rear wheel axis intersects the front edge of the parking frame 16 on the locus of reversing parking in the parking frame 16. Can be attached. As a result, when the driver performs the backward parking operation of the vehicle 1, the driver adjusts the reflecting mirror 8 in advance so that the first marker 10 coincides with the side surface of the host vehicle 1 reflected on the reflecting mirror 8 when viewed from the driver. In addition, by performing the steering operation so that the front end corner portion of the adjacent vehicle 18 is always reflected on the reflecting mirror 8 at the position of the second marker 12, the rear end of the vehicle 1 regardless of the position or posture of the vehicle 1 is started. The vehicle 1 can be moved backward while turning with an appropriate turning radius that is equal to or greater than the minimum turning radius so that the center of the axle intersects with the front edge of the parking frame 16 and is located near the center of the front edge. The parking frame 16 can be reliably parked near the center.

また、第3のマーカ14は、反射鏡8が、ドライバから見て第1のマーカ10が反射鏡8に映る自車両1の側面と一致するように予め調整され、且つ、予め最小回転半径で旋回しながら駐車枠16に後退駐車する軌跡上で後輪軸中心が駐車枠16の前縁と交差した場合に、車両1の旋回内側における駐車枠16の角部分が反射鏡8に映るような位置に規定されているので、ドライバは、車両1の後退駐車操作を行うときに、反射鏡8を、ドライバから見て第1のマーカ10が反射鏡8に映る自車両1の側面と一致するように予め調整し、且つ、旋回内側にある駐車枠16の角部分が常に第3のマーカ14の位置で反射鏡8に映るようにステアリング操作を行うことにより、例えば隣接車両が存在してもしなくても、駐車操作開始時の車両1の位置や姿勢に関わらず、後輪軸中心が駐車枠16の前縁と交差するときにその前縁の中央近傍に位置するように車両1を最小回転半径以上の適切な回転半径で旋回しながら後退させることができ、車両1を駐車枠16の中央近傍に駐車させることができる。したがって、ドライバのステアリング操作の自由度を残すことができる。   The third marker 14 is adjusted in advance so that the reflecting mirror 8 coincides with the side surface of the host vehicle 1 when the first marker 10 is reflected on the reflecting mirror 8 when viewed from the driver, and the third marker 14 has a minimum turning radius in advance. A position where the corner of the parking frame 16 on the inner side of the turning of the vehicle 1 is reflected on the reflecting mirror 8 when the center of the rear wheel axis intersects the front edge of the parking frame 16 on the trajectory of reversing parking in the parking frame 16 while turning. Therefore, when the driver performs the backward parking operation of the vehicle 1, the driver looks at the reflecting mirror 8 so that the first marker 10 matches the side surface of the host vehicle 1 reflected on the reflecting mirror 8. And the steering operation is performed so that the corner portion of the parking frame 16 on the inner side of the turn is always reflected on the reflecting mirror 8 at the position of the third marker 14. Even if the vehicle 1 Regardless of the position or posture, the vehicle 1 moves backward while turning at an appropriate turning radius equal to or greater than the minimum turning radius so that the center of the rear wheel axis intersects with the front edge of the parking frame 16 and is located near the center of the front edge. The vehicle 1 can be parked near the center of the parking frame 16. Therefore, the degree of freedom of the driver's steering operation can be left.
