Further, the AR display control unit 14 performs AR based on the AR display movement amount calculated by the movement amount calculation unit 12 by modifying the display image drawing form by the HUD light source 6 and adjusting the reference position by the optical device 8. An instruction is given to at least one of the HUD light source 6 and the optical actuator 9 to correct the display position (step ST14).
- the driver's eye position can be adjusted so that the eye position target point (reference position) matches. Further, it may be determined that the adjustment is completed when these processes are completed, and the driver may be notified by sound or display that driving preparation is ready. Thereby, the driver can start driving after confirming that the driving support preparation is completed.
- the movement of the sheet 5 in the Y-axis direction is limited, and the AR superimposed display cannot be corrected only by moving the sheet in the Y-axis direction.
- the eye position for AR superimposition can be adjusted more appropriately by deforming the image itself to be superimposed and displayed by the HUD light source 6 or the optical device 8 or correcting the reference position of the superimposed display. .

- an optimal AR display is realized in consideration of the driver's condition.
- Realizing the optimal AR display in consideration of the driver's condition means that the case where the head is displaced in the Z-axis direction (the front-rear direction of the vehicle), which is not considered to be a problem in the first embodiment,
- the position of the driver's eyes or its position such as when the driver gradually gets tired due to tilting or driving for a long time, or when the posture gradually changes in the left-right direction (X-axis direction)
- the correction amount of the reference position for AR display is calculated in consideration of movement.
- the position of the seat 5 is adjusted when the driver is seated (when boarding).
- the adjustment of the position of the seat 5 alone cannot cope with the optimal AR display. Is also possible. Since it is dangerous to adjust the position of the seat 5 during driving, it is assumed that the position adjustment of the seat 5 can only be performed at the time of starting or stopping.
- the seat position is adjusted at the start of boarding.
- the seat position in addition to the adjustment at the start of boarding, can be adjusted during driving. It can be done.
- the AR display control unit 14 corrects the drawing mode of the image emitted from the HUD light source 6 to obtain the AR. Adjust the overlay display. That is, the AR display control unit 14 according to the third embodiment instructs to correct the drawing mode of the image emitted from the HUD light source 6 based on the movement amount calculated by the movement amount calculation unit 12. .
- Adjustment of the position of the AR display itself is performed by the AR display control unit 14 (by the HUD light source 6 that receives an instruction from the AR display control unit 14 or an optical device that receives an instruction from the AR display control unit 14 8).
- the AR display control unit instructs the HUD light source 6 or the optical device 8 so that the target point (reference position) of the eye position coincides with the corrected eye position (after movement). Adjust by doing.
- (C) was emitted by the HUD light source 6 even when the AR display deviated from the object during driving after the driver was seated (ridden) and the initial adjustment was made.
- the image drawing mode is reduced (enlarged or reduced) or modified so that the AR display matches the object.
- the AR display object (AR marker) deviates from the target object during the operation after sitting and initial adjustment
- the form of drawing the image emitted by the HUD light source 6 is modified (scaled down).
- the AR display is corrected so as to match the object.
- the AR display object (AR marker) is displayed on the HUD 7 in accordance with the object.
- the driver's posture has changed from the time of sitting due to the habit of the driver or driving for a long time (for example, driving with the elbow on the driver's door)
- the position of the driver's head shifts with the change, the position of the driver's eyes may also shift.
- the vehicle since the vehicle is in operation, it cannot be adjusted so that the AR display object (AR marker) and the object coincide with each other by moving the seat 5. Therefore, in such a case (in the case of (C)), the drawing form of the image emitted from the HUD light source 6 is modified, or the reference position is adjusted by the optical device 8 using the optical actuator 9. Thus, the AR display is corrected so as to coincide with the object.
- the AR display object (AR marker) is adjusted following the driver's temporary eye position change such as several seconds, for example, 30 seconds or less, the adjustment is frequently repeated. On the other hand, it is difficult for the driver to see, and it seems that it does not make much sense.
- a timer event is generated every 10 minutes after key-on, and whether or not the driver's posture has deviated so much from the initially adjusted state, that is, the deviation between the eye position and the target point (reference position) is It is checked whether or not it is equal to or greater than a predetermined value. If the deviation is smaller than the predetermined value (not so much deviated), the AR display correction is not necessary, so the process is terminated and waits until the next 10 minutes.
- the driver's posture exceeds the predetermined tolerance from the initially adjusted state (deviation between the eye position and the target point (reference position) (height deviation, If the deviation in the left-right direction and the deviation in the front-rear direction of the vehicle are equal to or greater than a predetermined value), it is determined whether or not the AR display needs to be corrected.
- AR display correction (height direction correction, left-right direction correction, vehicle front-rear direction correction) is performed.
- the AR display is not corrected.
- the third embodiment that embodies the technical idea described above will be described in detail below.
- the configuration of the third embodiment is the same as that of the second embodiment except that there is a timer 15.
- the reference position for the superimposed display is moved by the optical device 8. It is preferable to deform the image itself emitted from the HUD light source 6.
- the movement amount calculation unit 12 calculates the movement amount of the seat 5 and the correction amount of the reference position of the AR display based on the deviation calculated by the deviation calculation unit 11. Similarly, with respect to the deviation in the left-right direction, it is often impossible to achieve the target point (reference position) of the eye position due to the movement of the sheet 5, so the AR display reference position is not the amount of movement of the sheet 5. It is better to deal with the correction.
- the movement amount calculation unit 12 calculates a correction amount for the reference position of the AR display with respect to a change in the position of the eye, such as a change in posture by tilting the neck that is detected even when the boarding is not started. .
- the AR display correction other than at the start of the boarding is not always performed, but may be performed only when it is shifted in the left-right direction for a predetermined time or more.
- the AR display control unit 14 deforms the image display object projected on the HUD 7 by the HUD light source 6 or the optical device 8 based on the correction amount of the AR display reference position calculated by the movement amount calculation unit 12. The AR display position is corrected.
- the processing flow at the start of boarding (at the time of initial adjustment) is the same as that described with reference to the flowchart shown in FIG. 9 in the second embodiment.
- the driver's eye position is adjusted so that the target point (reference position) of the eye position matches.
- the deviation calculating unit 11 acquires the driver's eye position information from the eye position detecting unit 3, and calculates the deviation to the target point (reference position). (Step ST22). At this time, the deviation calculated by the deviation calculation unit 11 is calculated not only in the height direction (Y-axis direction) but also in the left-right direction (X-axis direction) and the vehicle front-rear direction (Z-axis direction).
- the deviation calculation unit 11 is configured to measure the actual position of the driver's eyes when the driver is seated on the seat 5 (the actual measurement value in the height direction, the actual measurement value in the left-right direction when viewed from the front of the vehicle, the vehicle (Deviation in the front-rear direction) and a predetermined superimposed reference position displayed on the HUD 7 installed on the vehicle (deviation in the height direction, deviation in the left-right direction, deviation in the front-rear direction) calculate.
- the displacement count of the timer 15 is set to 0 (step ST24), and the process is terminated. That is, the displacement count of the timer 15 is a counter for measuring a continuous time in which the eye position is deviated from the reference position.
- step ST22 if the deviation calculated in step ST22 is equal to or greater than a predetermined value (YES in step ST23), whether or not the displacement count of timer 15 is equal to or greater than a predetermined count value. Is determined (step ST25).
- a count value corresponding to 30 seconds is set as the predetermined count value, and it is determined whether or not the count value corresponds to 30 seconds.
- the displacement count of the timer 15 is less than the predetermined count value (NO in step ST25)
- the eye position change state continues of change
- the driver's eye position is temporarily It is judged that it is only deviated. In this case, it is determined that the AR display correction is unnecessary at the present time, the displacement count of the timer 15 is incremented by 1 (step ST26), and the process returns to step ST22 again to acquire the position of the driver's eyes and calculate the deviation. Repeat from processing.
- the detection of the eye position by the eye position detection unit 3 is performed at every predetermined timing.
- the movement amount calculation unit 12 calculates the AR display movement amount based on the deviation calculated by the deviation calculation unit 11 (step ST27).
- the AR display control unit 14 corrects the AR display based on the AR display movement amount calculated by the movement amount calculation unit 12 by deforming the display image drawn by the HUD light source 6 or adjusting the optical device 8. Then, an instruction is given to at least one of the HUD light source 6 and the optical actuator 9 (step ST28). When the display correction is completed, the displacement count of the timer 15 is reset (step ST29), and the process ends.
- the AR display control unit 14 instructs the HUD light source 6 to correct the image drawing form in the height direction, to correct the left and right directions, and to enlarge or reduce the image drawing form,
- the optical device 8 is instructed to correct the reference position for superimposed display in the height direction, in the left-right direction, and in the front-rear direction.
- the driver's posture immediately returns to the original position. That is, when the driver's posture is deviated, even if the displacement count of the timer 15 is counted up in the determination of step ST23 because the deviation is equal to or greater than a predetermined value, the count value of the displacement count corresponds to 30 seconds. The driver's posture returns to the original position before the value to be reached (predetermined count value) is reached.
- the deviation of the driver's eye position is less than a predetermined value, so that the displacement count of the timer 15 is reset and the process ends.
- a state in which the deviation (deviation in the height direction, deviation in the left-right direction, deviation in the front-rear direction) is greater than or equal to a predetermined value and greater than or equal to the predetermined value is predetermined.
- the AR overlay display correction (height direction correction, left-right direction correction, front-rear direction correction) by the HUD light source 6 and the optical device 8 is performed only when it continues for more than the time. When only changes temporarily, the AR display correction is not performed.
- the AR display can be corrected not only for the eye position shift at the start of boarding but also for the eye position shift after the start of driving, Since it does not respond to the temporary eye position change, it is possible to perform the optimum AR superimposed display corresponding to the change in the driver's posture.

Or an individual identification signal from an individual identification device for identifying an individual identification number of a mobile phone.
- the dominant eye determination unit 18 determines a dominant eye that is different for each individual. As well as right-handed and left-handed, there are dominant eyes in the eyes. It is known that the dominant eye is an eye that focuses on the object, and the non-dominant eye complements the dominant eye by roughly grasping the whole and the background. Therefore, it is possible to perform more accurate AR superimposed display adapted to an individual by grasping which individual is the dominant eye and adjusting the AR display based on the position of the dominant eye.

Abstract
Description
例えば、特許文献1には、自動車等の車両において、ドアミラー等の部位自身に運転者の目を検出するカメラを内蔵し、あらかじめ設定した基準位置に運転者の目の位置が合うように、当該ドアミラー等の部位の位置や角度などを調整する自動調整装置が開示されている。
また、例えば特許文献1に示すような従来の装置のように自動でドアミラー等の部位の基準位置調整を行う手法を、HUDを用いたAR表示に適用することはできない、という課題もあった。
この発明は、車両の運転者が着座する運転席のシートを少なくとも高さ方向に自動的に移動可能な自動調整装置、自動調整システムおよび自動調整方法に関するものであり、自動車等の車両において、ヘッドアップディスプレイ(HUD)を用いたAR(Augmented Reality、拡張現実)表示を行う際に、運転者の目の位置を自動調整するため、運転席のシートの位置を自動的に移動させて調整するものである。
図1は、実施の形態1による自動調整装置とそれに接続される周辺機器の一例を示すブロック図である。自動調整装置1は、偏差算出部11、移動量算出部12および位置制御部13を備え、乗車検出部2、目の位置検出部3、シートアクチュエータ4が接続されている。また、シートアクチュエータ4はシート(電動シート)5に接続されている。
また、自動調整装置1と、目の位置検出部3およびシートアクチュエータ4が、シート自動調整システム10を構成する。
ここで、目の位置の目標点とは、車両に設置されたHUD上に表示されるあらかじめ定められたAR重畳表示の基準位置、すなわち、AR重畳表示が最適に重畳される運転者の目の位置であって、(X,Y,Z)の三次元で規定される。
すなわち、HUD上に表示される重畳表示の中心位置(基準位置)と運転者の目の位置の高さを一致されることにより、HUDに表示した重畳表示が対象物の位置と一致するように調整する。
なお、ここではフロントガラス投影型のHUD7を用いているが、サンバイザなどに透明プラスティックシートを取り付けて、そこにHUD用表示映像であるAR表示物(ARマーカ)101を投影する方式を用いてもよい。
そこで、図3(b)に示すように、運転者60の目61の位置が基準位置70と一致した高さになるように、運転席のシート5を調整する。
シートアクチュエータ4は、位置制御部13の指示に基づいて駆動し、シートレールに沿ってシート5の位置を移動させる。
まず初めに、乗車検出部2により運転者の乗車開始が検出されると、目の位置検出部3は運転者の目の位置の高さを検出する。
位置制御部13は、移動量算出部12により算出された着座移動量に基づいて、シートアクチュエータ4を制御して、着座位置を移動させる(ステップST3)。
これにより、運転者の体格の差異または乗車姿勢のくせなどにより運転者の目の高さが異なる場合であっても、運転者に応じてHUD上のAR表示を適切に行うことができる。
図7は、実施の形態2による自動調整装置とそれに接続される周辺機器の一例を示すブロック図である。なお、実施の形態1で説明したものと同様の構成には、同一の符号を付して重複した説明を省略する。以下に示す実施の形態2における自動調整装置20は、実施の形態1における自動調整装置1に比べるとAR表示制御部14をさらに備え、HUD用光源6と接続されている。
しかし、シート調整はいくらでも自由にできるわけではなく、当然のことながら上下方向(高さ方向)の移動に対して制限値(上限値または下限値)が設けられている。すなわち、シート5は、高さ方向の移動にかかる制限値(上限値または下限値)を有するものである。
まず初めに、乗車検出部2により運転者の乗車開始が検出されると、目の位置検出部3は運転者の目の位置の高さを検出する。
また、AR表示制御部14は、移動量算出部12により算出されたAR表示移動量に基づいて、HUD用光源6による表示画像の描画の形態の変形や光学装置8による基準位置の調整によりAR表示位置を補正するよう、HUD用光源6または光学アクチュエータ9の少なくとも一方に対して指示を行う(ステップST14)。
また、これらの処理を終えたときに調整完了と判断し、運転支援準備ができたことを音や表示で運転者に報知してもよい。これにより、運転者は、運転支援準備が完了したことを確認した上で運転を開始することができる。
図10は、実施の形態3による自動調整装置とそれに接続される周辺機器の一例を示すブロック図である。なお、実施の形態1,2で説明したものと同様の構成には、同一の符号を付して重複した説明を省略する。以下に示す実施の形態3における自動調整装置30は、実施の形態2の図8に示す自動調整装置20に比べると、タイマ15をさらに備えている。
すなわち、この実施の形態3におけるAR表示制御部14は、移動量算出部12により算出された移動量に基づいて、HUD用光源6から発せられた画像の描画の形態を補正するよう指示を行う。
この場合は、前述の実施の形態2により対応することができる。
この場合であっても、HUD用光源6により発せられた画像の描画の形態を縮尺(拡大または縮小補正)もしくは変形することにより、または、光学アクチュエータ9を用いて光学装置8の位置を調整することにより、AR表示が対象物と一致するように補正することができる。
そこで、このような場合((C)の場合)には、HUD用光源6が発する画像の描画の形態を変形したり、光学アクチュエータ9を用いて光学装置8による基準位置の調整を行ったりすることにより、AR表示が対象物と一致するように補正する。
この実施の形態3の構成としては、タイマ15があることを除いては、実施の形態2と同じである。
まず、運転者が乗車中であることを乗車検出部2が検知している間、あらかじめ定められた任意の周期(例えば10分ごと)でタイマイベントが発生し、目の位置検出部3が運転者の目の位置を検出する。
すなわち、タイマ15の変位カウントとは、目の位置が基準位置からずれている連続時間を計測するためのカウンタである。
このように、偏差(高さ方向の偏差、左右方向の偏差、前後方向の偏差)があらかじめ定められた値以上であって、かつ、当該あらかじめ定められた値以上である状態があらかじめ定められた時間以上継続した場合にのみ、HUD用光源6や光学装置8によるAR重畳表示の補正(高さ方向の補正、左右方向の補正、前後方向の補正)を行うようにしたので、運転者の姿勢が一時的に変化したにすぎない場合には、AR表示補正が実施されることはない。
図12は、実施の形態4による自動調整装置とそれに接続される周辺機器の一例を示すブロック図である。なお、実施の形態1~3で説明したものと同様の構成には、同一の符号を付して重複した説明を省略する。以下に示す実施の形態4における自動調整装置40は、実施の形態2の図8に示す自動調整装置20に比べると、個人調整量算出部16をさらに備え、個人調整用スイッチ31と接続されている。
図13は、個人調整量算出部16の構成を示すブロック図である。図13に示すように、個人調整量算出部16は、個人認証部17、利き目判定部18および個人調整量記憶部19から構成されている。
個人調整量記憶部19は、識別された個人ごとに利き目情報といった個人調整量が格納されている記憶部である。
(1)両目を開いた状態で、手前に設置された透明パネルに表示されたマーキングに、パネルの奥に設置された目標物が重なって見えるように、運転者に顔を動かしてもらうことにより、どちらが利き目であるかを判定する。
なお、利き目判定開始のトリガとして、個人調整用スイッチ31を用いることとしてもよい。
前述のとおり、利き目は対象物に対してピントを合わせ、利き目でない方の目は利き目の補完のため全体像をとらえることから、利き目でない方の目で得られる注視点は、利き目で得られる注視点よりもばらつきや誤差といった精度が悪いことが想定されるからである。
なお、(2)および(3)の場合には、個人調整用スイッチ31は不要である。
なお、一般的には利き目は右である割合が多いことが知られている。そのため、利き目のデフォルトの値を右としておくようにしてもよい。
個人調整量算出部16は、乗車検出部2で運転者の乗車開始が検出された時、または、車内に設置された個人調整用スイッチ31の押下が検出された時に、個人調整処理を開始する。
そして、ここで特定された個人の個人調整量のデータが、個人調整量記憶部19に記憶されているか否かを判定する(ステップST32)。
判定された利き目情報によって、その運転者に適した個人調整量を算出し(ステップST34)、個人調整量記憶部19に登録する(ステップST35)。
その後、算出された個人調整量を偏差算出部11に出力し(ステップST36)、この個人調整処理としては処理を終了する。
なお、ここでは、個人調整量として利き目情報を主として説明したが、個人調整量には同じ利き目であっても個人による見え方の違いなどによる調整量も含むものとする。
これにより、利き目などといった個人の影響を補正に反映させ、より最適なAR表示を実現することができる。
