Description

本発明は、運転者の体格や姿勢に合わせて座席を最適な位置に変更可能な座席位置制御装置に関する。   The present invention relates to a seat position control device that can change a seat to an optimal position in accordance with the physique and posture of a driver.

従来、携帯機を所持するドライバが着座した際に、メモリーに記憶されている初期位置に座席位置を変更する座席位置制御装置が知られている（例えば、特許文献１参照）。
特許文献１に記載の座席位置制御装置では、ユーザが使用車両の車種を変更したとき、そのユーザが違和感を生じることのないドライビングポジションに自動的に座席位置を変更することができる。今後、ＣＯ２低減のためにカーシェアリングが普及してくることを考慮すると、異なる車種でも運転者に適したドライビングポジションになることが好ましい。異なる車種でも極力近いドライビングポジションになるようにすれば、常に快適な姿勢で車両を運転することができ、安全性が高い。 2. Description of the Related Art Conventionally, a seat position control device is known that changes a seat position to an initial position stored in a memory when a driver carrying a portable device is seated (see, for example, Patent Document 1).
In the seat position control device described in Patent Literature 1, when the user changes the vehicle type of the vehicle in use, the seat position can be automatically changed to a driving position where the user does not feel uncomfortable. Considering that car sharing will become widespread in the future for reducing CO 2 , it is preferable that the driving position is suitable for the driver even in different vehicle types. By making the driving position as close as possible even with different models, the vehicle can always be driven in a comfortable posture, and safety is high.

特許文献１では、第１車両と第２車両におけるドライビングポジションを分割領域に区分して分割領域毎にデータを測定し統計を出すことが行われている。より具体的には、第１車両において、対象ユーザが選択したドライビングポジションの分割範囲が、統計データに当て嵌められて、対象ユーザにとって最適な第２車両のドライビングポジションの分割範囲が推定される。さらに、この推定されたドライビングポジションの分割範囲が第２車両に送信され、それに一致するように、第２車両においてドライビングポジションが制御される。   In Patent Document 1, the driving positions in the first vehicle and the second vehicle are divided into divided regions, data is measured for each divided region, and statistics are output. More specifically, in the first vehicle, the division range of the driving position selected by the target user is fitted to the statistical data, and the division range of the driving position of the second vehicle optimum for the target user is estimated. Further, the estimated driving position division range is transmitted to the second vehicle, and the driving position is controlled in the second vehicle so as to coincide with this.

特開２００８−７４３１３号公報JP 2008-74313 A

しかし、上述した特許文献１に記載の座席位置制御装置では、多数のユーザが座席に座ってデータを採取しなければならないため、手間がかかるという問題があった。また、被験者の人数が少ないと、統計データからの推定値から大きく外れる運転者が存在することになり、運転し難い態勢になるため、運転者の快適性を損ねる問題があった。   However, in the seat position control device described in Patent Document 1 described above, there is a problem that it takes time since many users have to sit on the seat and collect data. In addition, when the number of test subjects is small, there are drivers who deviate greatly from the estimated values based on the statistical data, which makes it difficult to drive, and thus there is a problem of impairing driver comfort.

本発明は、かかる従来技術の課題に鑑み、他の車両に乗り換えても快適に運転することができる位置に座席を移動できる座席位置制御装置を提供することを目的とする。   An object of the present invention is to provide a seat position control device that can move a seat to a position where it can be comfortably driven even if it is switched to another vehicle.

本発明はかかる課題を解決する手段としてなされたものである。
本発明は、車両の座席位置を変更する座席駆動手段と、車室内の特定位置に設けられ運転者の特定部位との距離を測定する測距手段と、運転者が携帯する携帯機と、該携帯機または携帯機と通信可能なサーバに、予め記憶された車室内の特定位置から運転者の運転時の姿勢におれる特定部位までの測距データに基づいて、前記測距手段による実測距離が前記記憶された測距データに一致するように前記座席駆動手段を制御する座席位置制御手段と、を備えたことを特徴とする。 The present invention has been made as a means for solving such a problem.
The present invention includes a seat driving means for changing a seat position of a vehicle, a distance measuring means for measuring a distance from a specific part of a driver provided at a specific position in a vehicle interior, a portable device carried by a driver, The distance measured by the distance measuring means based on distance measurement data from a specific position in the passenger compartment stored in advance in a portable device or a server communicable with the portable device to a specific portion in the driving posture of the driver. Comprises seat position control means for controlling the seat drive means so as to match the stored distance measurement data.

かかる発明によれば、携帯機または携帯機と通信可能なサーバに予め記憶された車室内の特定位置から運転者の運転時の体の特定部位までの距離である測距データに基づいて座席の位置が座席位置制御手段により変更されるので、当該構成を有する車両、すなわち、車室内の特定位置に運転者の特定部位との距離を測定する測距手段を備える車両に乗り換えることで、携帯機を備える全ての運転者にとって快適な運転ができる位置に座席が移動される。
ここで、座席の移動とは、座席のシートクッションの前後位置が移動することの他、シートバックの傾斜角度が変更されることも含む。 According to this invention, the seat of the seat is based on the distance measurement data that is the distance from the specific position in the vehicle compartment stored in advance to the portable device or the server that can communicate with the portable device to the specific part of the body when the driver is driving. Since the position is changed by the seat position control means, a portable device can be obtained by switching to a vehicle having the configuration, that is, a vehicle having a distance measuring means for measuring a distance from a specific position of the driver at a specific position in the passenger compartment. The seat is moved to a position where all of the drivers equipped with can comfortably drive.
Here, the movement of the seat includes not only the movement of the front / rear position of the seat cushion of the seat but also the change of the inclination angle of the seat back.

また、本発明において、好ましくは、前記測距データは、車室内の特定位置から運転者の頭、胸、または腰の部位に至る距離であるとよい。
すなわち、測距データは、車室内の特定位置、例えばハンドル中央部、またはルームミラー部、ルームランプ部、または頭上の天井部位置等が適当であり、これらの位置の少なくとも１箇所、または複数箇所から運転者の頭、胸、または腰の少なくとも１箇所の部位に至る距離を測距手段によって計測する。また、頭の位置でも目の位置、鼻の位置等の特定部位との距離を計測するとよい。
なお、測距手段としては、例えば、ＣＣＤカメラによる画像処理を用いることができるが、特に限定されない。 In the present invention, it is preferable that the distance measurement data is a distance from a specific position in the passenger compartment to the head, chest, or waist of the driver.
That is, the distance measurement data is suitably a specific position in the vehicle interior, for example, the center of the steering wheel, the room mirror, the room lamp, or the overhead ceiling, etc., and at least one or more of these positions A distance measuring means measures a distance from the driver to at least one part of the head, chest, or waist of the driver. Further, it is preferable to measure a distance from a specific part such as an eye position or a nose position even at the head position.
As the distance measuring means, for example, image processing by a CCD camera can be used, but it is not particularly limited.

運転者の体格や運転姿勢によって、運転中における運転者のハンドルからの距離、つまりハンドルから胸までの距離や、ルームミラーからの位置、つまりルームミラーから頭（目）までの距離は、車種が変わってもほぼ一定の距離が保持されている。
従って、このような車室内の特定位置と運転者の体の特定部位との距離をほぼ一定に保持するように座席位置を変更して制御することで、車種が変わって他の車両に乗り換えても快適に運転することができる位置に座席を移動できる。 Depending on the driver's physique and driving posture, the distance from the driver's steering wheel during driving, that is, the distance from the steering wheel to the chest, and the position from the rearview mirror, that is, the distance from the rearview mirror to the head (eyes) depends on the vehicle type. Even if it changes, a certain distance is maintained.
Therefore, by changing and controlling the seat position so that the distance between the specific position in the passenger compartment and the specific part of the driver's body is kept almost constant, the vehicle type changes and another vehicle is transferred. You can also move the seat to a position where you can drive comfortably.

また、本発明において、好ましくは、車両の安定走行中の運転者の位置を前記測距手段によって計測し、計測データに基づいて初期データまたは更新データとして前記携帯機またはサーバに記憶されるとよい。   In the present invention, it is preferable that the position of the driver during stable traveling of the vehicle is measured by the distance measuring means and stored in the portable device or server as initial data or update data based on the measured data. .

かかる構成によれば、ドライビングポジションの個人の測距データは、車室内に設けられた測距手段によって計測されて、携帯機またはサーバに記憶されるが、車両の安定走行中の運転者の位置を前記測距手段によって計測して測距データとする。
安定走行中の運転者の姿勢が最も自然な姿勢であるため、その位置での測距データを入手することで、座席位置の最適位置に制御できるようになる。 According to such a configuration, the personal ranging data of the driving position is measured by the ranging means provided in the passenger compartment and stored in the portable device or the server, but the position of the driver during the stable traveling of the vehicle Is measured by the distance measuring means to obtain distance measurement data.
Since the posture of the driver during the stable running is the most natural posture, it is possible to control to the optimum position of the seat position by obtaining the distance measurement data at that position.

また、運転姿勢が月日の経過とともに変化しても、一定期間毎、または安定走行の所定条件を満たす毎に計測データに測距データを更新していき、最新の運転姿勢に基づいて座席位置を制御することによって、車種が変わって他の車両に乗り換えても快適に運転することができる座席位置に正確に移動できる。   In addition, even if the driving posture changes with the passage of the month and day, the ranging data is updated to the measurement data every certain period or every time the predetermined conditions for stable driving are satisfied, and the seat position is based on the latest driving posture. By controlling the vehicle, it is possible to accurately move to a seat position that can be driven comfortably even if the vehicle type changes and another vehicle is switched.

本発明の座席位置制御装置では、他の車両に乗り換えても快適に運転することができる位置に座席を移動できる座席位置制御装置を提供することができる。   According to the seat position control device of the present invention, it is possible to provide a seat position control device that can move the seat to a position where it can be driven comfortably even if it is switched to another vehicle.

However, the dimensions, materials, shapes, relative positions, and the like of the component parts described in this embodiment are not intended to limit the scope of the present invention to that unless otherwise specified.

図１は、本発明の座席位置制御装置の一実施形態を模式的に示している。本実施形態の座席位置制御装置１は、座席位置制御手段３と、座席駆動手段５と、測距手段７と、携帯機９と、該携帯機９に接続されるサーバ１１（図２）とを有して構成されている。
座席位置制御手段３には、携帯機２を認識するための識別コードや、測距手段７によって計測した車室内の特定位置から運転者の体の特定部位までの距離の実測値や、携帯機９またはサーバ１１に記憶されている測距データの初期値または更新値を読み出して、車両側に取り込んで記憶する記憶部１３が設けられている。
この記憶部１３としては、ＲＡＭ、ＲＯＭ及びフラッシュメモリーなどの各種のメモリーを用いることができる。 FIG. 1 schematically shows an embodiment of a seat position control device of the present invention. The seat position control device 1 of the present embodiment includes a seat position control means 3, a seat drive means 5, a distance measuring means 7, a portable device 9, and a server 11 (FIG. 2) connected to the portable device 9. It is comprised.
The seat position control means 3 includes an identification code for recognizing the portable device 2, an actual measured value of a distance from a specific position in the passenger compartment measured by the distance measuring means 7 to a specific part of the driver's body, 9 or a storage unit 13 that reads out the initial value or the updated value of the distance measurement data stored in the server 11 and stores it in the vehicle side.
As the storage unit 13, various memories such as a RAM, a ROM, and a flash memory can be used.

また、座席位置制御手段３には、予め携帯機９またはサーバ１１に記憶された車室内の特定位置から運転者の体の特定部位までの距離である測距データに基づいて座席駆動手段５を駆動制御して、測距手段７による実測距離値が、前記記憶されている測距データに一致するように座席を移動制御する制御部１５が設けられている。
さらに、座席位置制御手段３には、運転者が携帯する携帯機９を検知する携帯機検知手段１７が設けられている。 Further, the seat position control means 3 is provided with seat drive means 5 based on distance measurement data which is a distance from a specific position in the passenger compartment previously stored in the portable device 9 or the server 11 to a specific part of the driver's body. A control unit 15 is provided for driving and controlling the movement of the seat so that the actually measured distance value by the distance measuring means 7 matches the stored distance measurement data.
Further, the seat position control means 3 is provided with portable device detection means 17 for detecting the portable device 9 carried by the driver.

そして、携帯機検知手段１７によって携帯機９が検知されたとき、携帯機９に記憶されている運転者のドライビングポジションの測距データに基づいて座席の位置が前記制御部１５により変更される。
ここで、ドライビングポジションの測距データとは、車両内に設けられたカメラなどの測距手段７によって計測された、車室内の特定位置から運転者の体の特定部位までの距離である。この点については、図３を用いて後述する。なお、ドライビングポジションの測距データを携帯機９に記憶させておくのではなく、図２に示すように、自動車販売会社などのオフィスに設置されたサーバ１１に記憶し、無線で携帯機９を介して座席位置制御手段３の記憶部１３にデータ通信するようにしてもよい。
なお、図１、２に示すように、座席位置制御手段３、および測距手段７、および座席駆動手段５は車両側に設置されており、それに対して携帯機９およびサーバ１１は運転者または車両外に設置される関係にある。 When the portable device 9 is detected by the portable device detection means 17, the position of the seat is changed by the control unit 15 based on distance measurement data of the driver's driving position stored in the portable device 9.
Here, the distance measurement data of the driving position is a distance from a specific position in the passenger compartment to a specific part of the driver's body, which is measured by distance measuring means 7 such as a camera provided in the vehicle. This will be described later with reference to FIG. The distance measurement data of the driving position is not stored in the portable device 9, but is stored in a server 11 installed in an office of an automobile sales company or the like as shown in FIG. The data may be communicated to the storage unit 13 of the seat position control means 3 via
As shown in FIGS. 1 and 2, the seat position control means 3, the distance measurement means 7, and the seat drive means 5 are installed on the vehicle side, whereas the portable device 9 and the server 11 are drivers or It is installed outside the vehicle.

図３は、運転者が座席に着席した状態を示している。図に示すように、車室内には運転者の姿勢を監視する測距手段７であるカメラ２０が設置されている。この位置は、本実施形態では、ルームミラー部又はサンバイザー部、ハンドル中央部及び運転者の頭上の天井部とされている。このカメラ２０は、例えば、運転者の姿勢に応じて座席２２の位置を変更するためのドライビングポジションの測距データの初期データおよび更新データを取得するために設けられている。このカメラ２０によって、カメラ２０から、運転者の特定位置、すなわち、頭部（目、鼻、頭頂部）、腕部、及び腰部までの距離Ｄ１〜Ｄ５が直接、測定される。ここで、特定位置は、車両の種類にかかわらず、運転者の特定部位までの距離がほぼ同等になるような位置が好ましい。
座席２２は、シートクッション部２２Ａが前後に水平移動し、シートバック部２２Ｂがシートクッション部２２Ａの後端部を中心に傾動する。本発明でいう座席２２の位置の変更には、シートクッション部２２Ａの前後移動することの他に、シートバック部２２Ｂが傾動することも含まれる。この前後移動と傾動により運転者をより快適な姿勢にすることができるからである。 FIG. 3 shows a state where the driver is seated on the seat. As shown in the figure, a camera 20 which is distance measuring means 7 for monitoring the driver's posture is installed in the passenger compartment. In this embodiment, this position is a room mirror part or a sun visor part, a handle center part, and a ceiling part above the driver's head. The camera 20 is provided, for example, for acquiring initial data and update data of distance measurement data of the driving position for changing the position of the seat 22 in accordance with the driver's posture. The camera 20 directly measures the distances D1 to D5 from the camera 20 to a specific position of the driver, that is, the head (eyes, nose, top of head), arm, and waist. Here, the specific position is preferably a position where the distance to the specific part of the driver is almost equal regardless of the type of vehicle.
In the seat 22, the seat cushion portion 22A horizontally moves back and forth, and the seat back portion 22B tilts around the rear end portion of the seat cushion portion 22A. In the present invention, the change of the position of the seat 22 includes tilting of the seat back portion 22B in addition to the back and forth movement of the seat cushion portion 22A. This is because the driver can be put in a more comfortable posture by this forward / backward movement and tilting.

次に、座席制御の処理の流れについて説明する。ここでは、サーバ１１と携帯機９とが通信する図２の形態を例に採り説明する。
図４に示すように、先ず、ステップＳ１において、車両に設置されている座席位置制御手段３内の携帯機検知手段１７が、座席に座った運転者が携帯する携帯機９を認識する。これは、記憶部１３に記憶された識別コードと、携帯機９から送信された識別コードが一致するか否かを確認することにより行うことができる。携帯機９は電源をオンにした状態では電波を発信しており、運転者が座席に座ったら確実に通信範囲に入るように携帯機検知手段１７の受信強度が設定されている。次いで、ステップＳ２において、携帯機検知手段１７が携帯機９に電波を送り、ステップＳ１とは反対に今度は携帯機９が車両側の携帯機検知手段１７を認識する。 Next, the flow of seat control processing will be described. Here, the embodiment shown in FIG. 2 in which the server 11 communicates with the portable device 9 will be described as an example.
As shown in FIG. 4, first, in step S1, the portable device detection means 17 in the seat position control means 3 installed in the vehicle recognizes the portable device 9 carried by the driver sitting on the seat. This can be performed by checking whether or not the identification code stored in the storage unit 13 matches the identification code transmitted from the portable device 9. The portable device 9 emits radio waves when the power is turned on, and the reception intensity of the portable device detection means 17 is set so as to surely enter the communication range when the driver sits on the seat. Next, in step S2, the portable device detection means 17 sends a radio wave to the portable device 9, and this time the portable device 9 recognizes the portable device detection means 17 on the vehicle side, contrary to step S1.

次いで、ステップＳ３において、携帯機９がインターネットを介してサーバ１１にアクセスし、運転者のドライビングポジションの測距データ（予め記憶され測距データ）があるか否かを探索する。次いで、ステップＳ４において、前記探索の結果、携帯機９がドライビングポジションの測距データがあることを認識したらステップＳ５に進み、携帯機９が車両側の座席位置制御手段３の記憶部１３にドライビングポジションの測距データを送信する。   Next, in step S3, the portable device 9 accesses the server 11 via the Internet, and searches whether there is distance measurement data (preliminarily stored distance measurement data) of the driver's driving position. Next, in step S4, if the portable device 9 recognizes that there is distance measurement data of the driving position as a result of the search, the process proceeds to step S5, and the portable device 9 drives to the storage unit 13 of the seat position control means 3 on the vehicle side. Sends distance measurement data.

次いで、ステップＳ６に進み、座席の位置が調整可能か判定する。すなわちシートクッション部２２Ａの前後調整やシートバック部２２Ｂの前傾、後傾の調整が、その調整範囲の端末に突き当たりこれ以上調整できない状態になっていないか判定する。調整できる余裕があればステップＳ７に進んで、座席位置制御手段３の制御部１５で、座席駆動手段５を制御して、予め記憶されている運転者のドライビングポジションの測距データに基づいて、その測距データに一致するようにシートクッション部２２Ａが移動され、またシートバック部２２Ｂの傾きが変更される。そして、ステップＳ１に戻る。   Next, the process proceeds to step S6, and it is determined whether the seat position can be adjusted. That is, it is determined whether the front / rear adjustment of the seat cushion portion 22A or the forward / backward adjustment of the seat back portion 22B hits the terminal in the adjustment range and is not in a state where it can no longer be adjusted. If there is a margin that can be adjusted, the process proceeds to step S7, where the controller 15 of the seat position control means 3 controls the seat drive means 5, and based on the distance measurement data of the driver's driving position stored in advance, The seat cushion portion 22A is moved so as to coincide with the distance measurement data, and the inclination of the seat back portion 22B is changed. Then, the process returns to step S1.

一方、ステップＳ４において、前記探索の結果、携帯機９に、ドライビングポジションの測距データ（予め記憶され測距データ）があることを認識しなかったらステップＳ８に進み、運転者に座席の位置を自分で合わせるように、携帯機９が車両側に信号を送信し、車室内のモニターやランプを介して運転者に知らせる。
次いで、ステップＳ９において座席の位置合わせが終了したか否かを判断する。座席の位置合わせが終了していない場合には、ステップＳ８に戻り、座席の位置合わせが終了している場合には、ステップＳ１０に進む。そして、車両の前後方向及び横方向の加速度が所定値以下であるか否かを判断する。所定値以下でなければ、本ステップの判断を繰り返し継続し、所定値以下であればステップＳ１１において、車両が直進中であるか否かを判断する。車両が直進中でなければステップＳ１０に戻り、直進中であれば図５に示すステップＳ１２に進む。 On the other hand, in step S4, as a result of the search, if it is not recognized that the portable device 9 has ranging data (driving data stored in advance) for the driving position, the process proceeds to step S8, and the driver is given the seat position. The portable device 9 transmits a signal to the vehicle side so that the driver can adjust it by himself / herself, and informs the driver via a monitor and a lamp in the passenger compartment.
Next, in step S9, it is determined whether or not the seat alignment has been completed. If the seat alignment has not been completed, the process returns to step S8. If the seat alignment has been completed, the process proceeds to step S10. Then, it is determined whether the longitudinal acceleration and the lateral acceleration of the vehicle are equal to or less than a predetermined value. If it is not less than the predetermined value, the determination in this step is continuously repeated, and if it is less than the predetermined value, it is determined in step S11 whether or not the vehicle is traveling straight. If the vehicle is not traveling straight, the process returns to step S10. If the vehicle is traveling straight, the process proceeds to step S12 shown in FIG.

図５に示すステップＳ１２では、運転者が前方を向いているか否かが判断される。運転者が前方を向いていなければステップＳ１０に戻り、運転者が前方を向いていればステップＳ１３に進む。ステップＳ１３では運転者のドライビングポジション（運転者の特定部位の位置）の計測がカメラ２０を用いて行われる。次いで、ステップＳ１４において、所定回数計測が終了したか否かが判断される。所定回数計測が終了していなければステップＳ１０に戻り、計測が終了していればステップＳ１５に進む。ステップＳ１５では運転者のドライビングポジションの測距データの平均値処理が行われる。次いで、ステップＳ１６において車両側の座席位置制御手段３は携帯機９にドライビングポジションの測距情報を送信する。次いで、ステップＳ１７においてこの情報はドライビングポジションの測距データとしてサーバ１１に記憶される。そして、ステップＳ１に戻る。   In step S12 shown in FIG. 5, it is determined whether or not the driver is facing forward. If the driver is not facing forward, the process returns to step S10, and if the driver is facing forward, the process proceeds to step S13. In step S <b> 13, the driver's driving position (the position of the driver's specific part) is measured using the camera 20. Next, in step S14, it is determined whether or not the predetermined number of measurements has been completed. If the predetermined number of measurements has not been completed, the process returns to step S10, and if the measurement has been completed, the process proceeds to step S15. In step S15, average value processing of distance measurement data of the driver's driving position is performed. Next, in step S <b> 16, the vehicle-side seat position control means 3 transmits driving position ranging information to the portable device 9. Next, in step S17, this information is stored in the server 11 as distance measurement data of the driving position. Then, the process returns to step S1.

上述した実施形態では、携帯機検知手段１７によって携帯機９が検知されたとき、携帯機９に予め記憶された運転者のドライビングポジションの測距データに基づいて、該測距データにカメラ２０による実測の距離が一致するように座席の位置を座席位置制御手段３の制御部１５によって変更されるので、当該構成、すなわち、同一の車室内位置に測距手段７を有する車両に乗り換えると、携帯機９を備える全ての運転者にとって快適な運転ができる位置に座席が移動する。   In the embodiment described above, when the portable device 9 is detected by the portable device detection means 17, based on the distance measurement data of the driver's driving position stored in advance in the portable device 9, the distance measurement data is obtained by the camera 20. Since the position of the seat is changed by the control unit 15 of the seat position control means 3 so that the actually measured distances coincide with each other, if the vehicle is changed to a vehicle having the distance measuring means 7 at the same vehicle interior position, The seat moves to a position where all the drivers equipped with the machine 9 can drive comfortably.

また、車両の前後方向及び横方向の加速度が所定値以下である車両の安定走行中の運転者の位置を測距手段７によって計測して測距データとして、携帯機９またはサーバ１１に記憶するので、つまり安定走行中の運転者の姿勢が最も自然な姿勢であるため、その位置での測距データを入手することで、座席位置の最適位置に制御できるようになる。   Further, the position of the driver during stable traveling of the vehicle whose longitudinal and lateral accelerations of the vehicle are below a predetermined value is measured by the distance measuring means 7 and stored as distance measurement data in the portable device 9 or the server 11. Therefore, since the driver's posture during the stable running is the most natural posture, the distance measurement data at that position can be obtained to control the optimum position of the seat position.

また、運転姿勢が月日の経過とともに変化しても、一定期間毎、または安定走行の所定条件を満たす毎に計測データに測距データを更新していき、最新の運転姿勢に基づいて座席位置を制御することによって、車種が変わって他の車両に乗り換えても快適に運転することができる座席位置に正確に移動できる。   In addition, even if the driving posture changes with the passage of the month and day, the ranging data is updated to the measurement data every certain period or every time the predetermined conditions for stable driving are satisfied, and the seat position is based on the latest driving posture. By controlling the vehicle, it is possible to accurately move to a seat position that can be driven comfortably even if the vehicle type changes and another vehicle is switched.

以上、本発明を説明してきたが、本発明は上述した実施形態にのみ限定されるものではなく、その本質を逸脱しない範囲で、他の種々の変形が可能であることはいうまでもない。   Although the present invention has been described above, the present invention is not limited to the above-described embodiments, and it goes without saying that other various modifications are possible without departing from the essence thereof.

本発明の座席位置制御装置では、他の車両に乗り換えても快適に運転することができる位置に座席を移動できるので、座席を有する車両の全てに適用することが可能である。   In the seat position control device of the present invention, the seat can be moved to a position where it can be driven comfortably even if the vehicle is switched to another vehicle, and therefore it can be applied to all vehicles having a seat.
