Description

車両用入力装置Vehicle input device
　本発明は、車両用入力装置に関し、特に、自動車などの車両のステアリングに設けた車両用入力装置に関するものである。 The present invention relates to an input device for a vehicle, and more particularly to an input device for a vehicle provided in steering of a vehicle such as an automobile.
　従来の車両用入力装置は、ステアリングのスポーク部に配置された複数のタッチセンサで構成されたタッチ入力部と、検出部と、判定部と、制御部から構成されており、前記判定部は、前記タッチ入力部から入力された操作を選択し、前記制御部は、選択された操作に基づいてカーナビゲーション装置などの機器を制御するものであった（特許文献１参照）。 A conventional vehicle input device includes a touch input unit configured by a plurality of touch sensors arranged in a spoke spoke unit, a detection unit, a determination unit, and a control unit. The operation input from the touch input unit is selected, and the control unit controls a device such as a car navigation device based on the selected operation (see Patent Document 1).
特開２００９－２９８２８５号公報JP 2009-298285 A
　しかし、従来の車両用入力装置は、ユーザが、ステアリングホイールを把持した状態で、タッチ入力部を操作する。通常、タッチ入力部が、ステアリング面に対してユーザ側に配置される場合、タッチ入力部を操作する指は親指となる。ユーザが、親指でタッチ入力部を直線的になぞる操作（ジェスチャー操作）を行おうとすると、ユーザが、直線になぞっているつもりでも、その軌跡は、親指の構造上、意図した直線に対して斜めになぞってしまったり、あるいは円弧としてなぞってしまい、直線として検出されず、操作性が悪くなってしまうという問題点があった。 However, in the conventional vehicle input device, the user operates the touch input unit while holding the steering wheel. Usually, when the touch input unit is disposed on the user side with respect to the steering surface, the finger operating the touch input unit is the thumb. When the user tries to perform a linear operation (gesture operation) of tracing the touch input unit with the thumb, even if the user intends to trace the straight line, the locus is oblique to the intended straight line due to the structure of the thumb. Or traced as an arc, it was not detected as a straight line, and the operability deteriorated.
　そこで本発明は、ステアリング上のタッチ入力部を操作する親指の向きを検出し、操作性が良好な車両用入力装置を提供することを目的とする。 Therefore, an object of the present invention is to provide an input device for a vehicle that detects the direction of a thumb that operates a touch input unit on a steering wheel and has good operability.
　本発明は、前記課題を解決するために、ステアリングに設けられユーザの操作を検出するタッチ入力部と、前記タッチ入力部に対する所定の荷重を検出する荷重検出部とを備えた車両用入力装置において、前記荷重検出部が所定の荷重を検出した前後の前記タッチ入力部の検出値によって、前記ユーザの指の向きを検出するものである。 In order to solve the above-described problem, the present invention provides a vehicle input device including a touch input unit that is provided on a steering wheel and detects a user operation, and a load detection unit that detects a predetermined load on the touch input unit. The direction of the user's finger is detected based on detection values of the touch input unit before and after the load detection unit detects a predetermined load.
　また、前記荷重検出部は、前記タッチ入力部の背後に位置し前記タッチ入力部を押す操作によって閉じる押釦スイッチである。 The load detection unit is a pushbutton switch that is located behind the touch input unit and is closed by an operation of pressing the touch input unit.
　本発明によれば、所期の目的を達成でき、ステアリング上のタッチ入力部を操作する親指の向きを検出し、操作性が良好な車両用入力装置を提供することができる。 According to the present invention, it is possible to provide a vehicle input device that can achieve the intended purpose, detect the direction of the thumb that operates the touch input unit on the steering wheel, and has good operability.

　以下、図に基づいて、本発明の実施形態の車両用入力装置を説明する。 Hereinafter, a vehicle input device according to an embodiment of the present invention will be described with reference to the drawings.
　本発明の実施形態の車両用入力装置１００は、自動車などの車両に搭載されるものである。前記車両は、ステアリング１０と、車載電子機器２０と、を備えている。前記車両のユーザ（通常、運転者）が、車両用入力装置１００を操作すると、制御部３０は、その操作に応じた各種動作を車載電子機器２０に実行させる。ステアリング１０は、前記車両の操舵装置の一部であり、本体部１１と、ステアリングホイール１２と、を備えている。 The vehicle input device 100 according to the embodiment of the present invention is mounted on a vehicle such as an automobile. The vehicle includes a steering 10 and an in-vehicle electronic device 20. When a user (usually a driver) of the vehicle operates the vehicle input device 100, the control unit 30 causes the in-vehicle electronic device 20 to perform various operations according to the operation. The steering 10 is a part of the vehicle steering apparatus, and includes a main body 11 and a steering wheel 12.
　本体部１１は、前記車両の図示しないステアリングシャフトと接続される中央部とスポーク部とを備えたものである。本実施形態では、本体部１１の右側に車両用入力装置１００を備える。本体部１１には、車両用入力装置１００のタッチ入力部１１０の操作面のみが露出する。 The main body 11 includes a central portion and a spoke portion connected to a steering shaft (not shown) of the vehicle. In the present embodiment, the vehicle input device 100 is provided on the right side of the main body 11. Only the operation surface of the touch input unit 110 of the vehicle input device 100 is exposed to the main body unit 11.
　ステアリングホイール１２は、本体部１１に取り付けられ、前記ユーザが、前記車両を操舵する際に握るリング形状のハンドルのグリップ部材である。 The steering wheel 12 is attached to the main body 11, and is a grip member of a ring-shaped handle that is gripped when the user steers the vehicle.
　車載電子機器２０は、オーディオ装置、カーナビゲーション装置等であり、制御部３０と電気的に接続され、制御部３０から受信した制御信号に従って動作する。また、車載電子機器２０は、図示しない表示部を備えている。 The in-vehicle electronic device 20 is an audio device, a car navigation device or the like, and is electrically connected to the control unit 30 and operates according to a control signal received from the control unit 30. The on-vehicle electronic device 20 includes a display unit (not shown).
　車両用入力装置１００は、タッチ入力部１１０を構成するタッチパネル部材１２０と、スイッチ機構１３０とを備えている。 The vehicle input device 100 includes a touch panel member 120 constituting a touch input unit 110 and a switch mechanism 130.
　タッチ入力部１１０であるタッチパネル部材１２０は、ユーザが、親指等でその操作面１１０ａ上を所定の軌跡を描くようになぞる操作（以下、ジェスチャー操作と言う）を行った際に、操作面１１０ａに触れた位置を検出するものであり、第１のシート状部材１１１と、第２のシート状部材１１２と、を積層し一体としたものである。第１のシート状部材１１１は、表面カバーとなる透過性かつ屈曲性のある材料からなる。第２のシート状部材１１２は、親指などの被検出体が操作面１１０ａと接触した位置を検出するためセンサが、前面側に設けられた透過性のかつ屈曲性のある材料からなる。 When the user performs an operation (hereinafter referred to as a gesture operation) to trace a predetermined locus on the operation surface 110a with a thumb or the like, the touch panel member 120 as the touch input unit 110 is applied to the operation surface 110a. The touched position is detected, and the first sheet-like member 111 and the second sheet-like member 112 are laminated and integrated. The first sheet-like member 111 is made of a permeable and flexible material that serves as a surface cover. The second sheet-like member 112 is made of a permeable and flexible material in which a sensor is provided on the front side in order to detect a position where a detection object such as a thumb contacts the operation surface 110a.
　タッチパネル部材１２０は、ユーザがタッチする操作面１１０ａと、ユーザがタッチできない周縁部１１０ｂと、センシング信号を制御部３０へ送る図示しない引出し線を有する。 The touch panel member 120 has an operation surface 110 a that the user touches, a peripheral edge 110 b that cannot be touched by the user, and a lead line (not shown) that sends a sensing signal to the control unit 30.
　第２のシート状部材１１２は、投影型静電容量方式のセンサシートであり、図３で示すように、指等の被検出体の位置を検出するための複数のセンサ（検出電極）１１２０を有するものである。 The second sheet-like member 112 is a projected capacitive sensor sheet, and includes a plurality of sensors (detection electrodes) 1120 for detecting the position of a detection object such as a finger as shown in FIG. It is what you have.
　第２のシート状部材１１２は、図２で示すように、Ｘ方向における被検出体の位置を検出するための第１のセンサ列１１２ａを有する層と、Ｙ方向における被検出体の位置を検出するための第２のセンサ列１１２ｂを有する層を重ね合わせて構成されている。第１のセンサ列１１２ａと第２のセンサ列１１２ｂが合わさることにより、結果的に、第２のシート状部材１１２には、センサ１１２０が、マトリックス状に配置されることになる。第１のセンサ列１１２ａと第２のセンサ列１１２ｂは、各々、制御部３０と電気的に接続されている。なお、図４で示すように、本実施形態では、第１のセンサ列１１２ａが８本、第２のセンサ列１１２ｂが１０本、設けられている。なお、各センサ列１１２ａ、１１２ｂの間隔は、６．５ｍｍである。 As shown in FIG. 2, the second sheet-like member 112 detects a layer having a first sensor array 112 a for detecting the position of the detected object in the X direction and the position of the detected object in the Y direction. The layer having the second sensor array 112b for superimposing is configured to overlap. As a result of combining the first sensor row 112a and the second sensor row 112b, the sensors 1120 are arranged in a matrix on the second sheet-like member 112. The first sensor row 112a and the second sensor row 112b are each electrically connected to the control unit 30.
