　本開示の一態様に係る入力装置は、車両に搭載される入力装置であって、前記車両のステアリングホイールの操舵に連動して回転する回転体と、前記回転体の回転角を非接触で検出することにより、前記ステアリングホイールの操舵角を検出する操舵角検出センサと、所定方向に操作可能なレバーと、前記レバーの操作を非接触で検出するレバー操作検出センサと、前記操舵角検出センサ及び前記レバー操作検出センサの各々が実装された基板と、を備える。 The input device according to one aspect of the present disclosure is an input device mounted on a vehicle, and detects a rotating body that rotates in conjunction with steering of the steering wheel of the vehicle and a rotation angle of the rotating body in a non-contact manner. A steering angle detection sensor that detects the steering angle of the steering wheel, a lever that can be operated in a predetermined direction, a lever operation detection sensor that detects the operation of the lever in a non-contact manner, the steering angle detection sensor, and the steering angle detection sensor. A substrate on which each of the lever operation detection sensors is mounted is provided.
　本態様によれば、操舵角検出センサ及びレバー操作検出センサの各々は、同一の基板に実装された非接触センサである。これにより、基板とレバーユニット及び操舵角検出ユニットの各々とを電気的に接続するための電気的接続機構を省略することができる。その結果、入力装置における電気的接続不良の発生を抑制することができる。 According to this aspect, each of the steering angle detection sensor and the lever operation detection sensor is a non-contact sensor mounted on the same substrate. Thereby, the electrical connection mechanism for electrically connecting the substrate and each of the lever unit and the steering angle detection unit can be omitted. As a result, it is possible to suppress the occurrence of electrical connection failure in the input device.
　例えば、前記操舵角検出センサは、前記基板の第１の面に実装され、前記レバー操作検出センサは、前記基板の前記第１の面と反対側の第２の面に実装されているように構成してもよい。 For example, the steering angle detection sensor is mounted on the first surface of the substrate, and the lever operation detection sensor is mounted on the second surface of the substrate opposite to the first surface. It may be configured.
　本態様によれば、操舵角検出センサ及びレバー操作検出センサは、基板の異なる面に実装されているので、操舵角検出センサ及びレバー操作検出センサが基板の同一の面に実装されている場合と比べて、基板をコンパクト化することができる。 According to this aspect, since the steering angle detection sensor and the lever operation detection sensor are mounted on different surfaces of the substrate, the steering angle detection sensor and the lever operation detection sensor are mounted on the same surface of the substrate. In comparison, the substrate can be made more compact.
　例えば、前記基板を平面視した場合に、前記操舵角検出センサは、前記レバー操作検出センサと重ならない位置に配置されているように構成してもよい。 For example, when the substrate is viewed in a plan view, the steering angle detection sensor may be configured to be arranged at a position that does not overlap with the lever operation detection sensor.
　本態様によれば、操舵角検出センサ及びレバー操作検出センサの離間距離を確保することができる。その結果、操舵角検出センサ及びレバー操作検出センサの各々が、互いに影響を及ぼし合うのを抑制することができ、操舵角検出センサ及びレバー操作検出センサの各検出精度を高めることができる。 According to this aspect, it is possible to secure the separation distance between the steering angle detection sensor and the lever operation detection sensor. As a result, it is possible to suppress each of the steering angle detection sensor and the lever operation detection sensor from affecting each other, and it is possible to improve the detection accuracy of each of the steering angle detection sensor and the lever operation detection sensor.
　例えば、前記レバーは、第１のレバーと、前記基板を挟んで前記第１のレバーと反対側に配置された第２のレバーと、を含み、前記レバー操作検出センサは、前記基板の第１の端部に実装され、前記第１のレバーの操作を非接触で検出する第１のレバー操作検出センサと、前記基板の前記第１の端部と反対側の第２の端部に実装され、前記第２のレバーの操作を非接触で検出する第２のレバー操作検出センサと、を含み、前記操舵角検出センサは、前記基板の前記第１の端部と前記第２の端部との間の中間部に実装されているように構成してもよい。 For example, the lever includes a first lever and a second lever arranged on the side opposite to the first lever with the substrate interposed therebetween, and the lever operation detection sensor is a first lever of the substrate. It is mounted on the end of the first lever operation detection sensor that detects the operation of the first lever in a non-contact manner, and on the second end of the substrate opposite to the first end. A second lever operation detection sensor that detects the operation of the second lever in a non-contact manner, and the steering angle detection sensor includes the first end portion and the second end portion of the substrate. It may be configured to be mounted in the middle part between.
　本態様によれば、操舵角検出センサ、第１のレバー操作検出センサ及び第２のレバー操作検出センサの各離間距離を確保することができる。その結果、操舵角検出センサ、第１のレバー操作検出センサ及び第２のレバー操作検出センサの各々が、互いに影響を及ぼし合うのをより効果的に抑制することができる。 According to this aspect, it is possible to secure the separation distances of the steering angle detection sensor, the first lever operation detection sensor, and the second lever operation detection sensor. As a result, it is possible to more effectively suppress each of the steering angle detection sensor, the first lever operation detection sensor, and the second lever operation detection sensor from affecting each other.
　例えば、前記基板は、前記ステアリングホイールに連結されたステアリングシャフトであって、前記ステアリングホイールの操舵により回転するステアリングシャフトを挿通するための切り欠き部を有し、前記第１のレバー操作検出センサ及び前記第２のレバー操作検出センサは、前記切り欠き部を挟んで互いに反対側に配置されているように構成してもよい。 For example, the substrate is a steering shaft connected to the steering wheel, has a notch for inserting a steering shaft that rotates by steering the steering wheel, and has the first lever operation detection sensor and the first lever operation detection sensor. The second lever operation detection sensor may be configured to be arranged on opposite sides of the notch portion.
　本態様によれば、第１のレバー操作検出センサ及び第２のレバー操作検出センサは、基板の切り欠き部を挟んで互いに反対側に配置されているので、第１のレバー操作検出センサ及び第２のレバー操作検出センサの離間距離を確保することができる。その結果、第１のレバー操作検出センサ及び第２のレバー操作検出センサの各々が、互いに影響を及ぼし合うのをより効果的に抑制することができる。 According to this aspect, since the first lever operation detection sensor and the second lever operation detection sensor are arranged on opposite sides of each other with the notch of the substrate interposed therebetween, the first lever operation detection sensor and the second lever operation detection sensor It is possible to secure the separation distance of the lever operation detection sensor of 2. As a result, it is possible to more effectively suppress each of the first lever operation detection sensor and the second lever operation detection sensor from affecting each other.
　例えば、前記入力装置は、さらに、前記基板に実装され、前記操舵角検出センサ及び前記レバー操作検出センサの各々からの検出信号に基づいて前記車両を制御する電子制御ユニットを備えるように構成してもよい。 For example, the input device is further configured to include an electronic control unit mounted on the substrate and controlling the vehicle based on detection signals from each of the steering angle detection sensor and the lever operation detection sensor. May be good.
　本態様によれば、基板にはさらに電子制御ユニットが実装されているので、操舵角検出センサ、レバー操作検出センサ及び電子制御ユニットを同一の基板に集約することができる。その結果、入力装置をコンパクト化することができる。 According to this aspect, since the electronic control unit is further mounted on the board, the steering angle detection sensor, the lever operation detection sensor, and the electronic control unit can be integrated on the same board. As a result, the input device can be made compact.
　例えば、前記入力装置は、さらに、前記回転体を回転可能に支持する回転体ホルダと、前記回転体に取り付けられた操舵角検出用磁石と、を備え、前記操舵角検出センサは、前記操舵角検出用磁石が前記回転体とともに前記回転体ホルダに対して回転することにより生じる磁界の変化を非接触で検出する磁気センサであるように構成してもよい。 For example, the input device further includes a rotating body holder that rotatably supports the rotating body, and a steering angle detecting magnet attached to the rotating body, and the steering angle detecting sensor includes the steering angle. The detection magnet may be configured to be a magnetic sensor that non-contactly detects changes in the magnetic field caused by rotation of the rotating body with respect to the rotating body holder.
　本態様によれば、操舵角検出センサは磁気センサであり、操舵角検出用磁石が回転体とともに回転体ホルダに対して回転することにより生じる磁界の変化を非接触で検出するので、ステアリングホイールの操舵角を非接触で容易に検出することができる。 According to this aspect, the steering angle detection sensor is a magnetic sensor, and the change in the magnetic field generated by the rotation of the steering angle detection magnet with respect to the rotating body holder together with the rotating body is detected in a non-contact manner. The steering angle can be easily detected without contact.
　例えば、前記入力装置は、さらに、前記基板を支持する筐体を備え、前記筐体は前記基板の前記操舵角検出センサが実装された面を覆い、前記操舵角検出センサは、前記操舵角検出用磁石の磁界の変化を、前記筐体を介して検出するように構成してもよい。 For example, the input device further includes a housing that supports the substrate, the housing covers the surface of the substrate on which the steering angle detection sensor is mounted, and the steering angle detection sensor detects the steering angle. The change in the magnetic field of the magnet may be detected via the housing.
　本態様によれば、基板の操舵角検出センサが実装された面は、筐体により覆われているので、基板の表面に塵埃や液体等の異物が侵入することを防ぎ、基板の電気回路の絶縁劣化を抑制することができる。 According to this aspect, since the surface on which the steering angle detection sensor of the substrate is mounted is covered with a housing, it is possible to prevent foreign substances such as dust and liquid from entering the surface of the substrate and to prevent foreign matter such as dust and liquid from entering the surface of the electric circuit of the substrate. Insulation deterioration can be suppressed.
　例えば、前記入力装置は、さらに、前記レバーを操作可能に支持するレバーホルダと、前記レバーホルダに配置され、前記レバーの操作に応じて前記レバーホルダに対して変位するレバー操作検出用磁石と、を備え、前記レバー操作検出センサは、前記レバー操作検出用磁石が前記レバーホルダに対して変位することにより生じる磁界の変化を非接触で検出する磁気センサであるように構成してもよい。 For example, the input device further includes a lever holder that operably supports the lever, a lever operation detection magnet that is arranged in the lever holder and is displaced with respect to the lever holder in response to the operation of the lever. The lever operation detection sensor may be configured to be a magnetic sensor that non-contactly detects a change in the magnetic field caused by the displacement of the lever operation detection magnet with respect to the lever holder.
　本態様によれば、レバー操作検出センサは磁気センサであり、レバー操作検出用磁石がレバーホルダに対して変位することにより生じる磁界の変化を非接触で検出するので、レバーの操作を非接触で容易に検出することができる。 According to this aspect, the lever operation detection sensor is a magnetic sensor, and the change in the magnetic field caused by the displacement of the lever operation detection magnet with respect to the lever holder is detected in a non-contact manner, so that the lever operation is non-contact. It can be easily detected.
　例えば、前記入力装置は、さらに、前記基板を支持する筐体を備え、前記筐体は前記基板の前記レバー操作検出センサが実装された面を覆い、前記レバー操作検出センサは、前記レバー操作検出用磁石の磁界の変化を、前記筐体を介して検出するように構成してもよい。 For example, the input device further includes a housing that supports the board, the housing covers the surface of the board on which the lever operation detection sensor is mounted, and the lever operation detection sensor detects the lever operation. The change in the magnetic field of the magnet may be detected via the housing.
