　本発明は、自動車の速度を制御するためのアクセル操作装置に関する。 The present invention relates to an accelerator operating device for controlling the speed of an automobile.
　従来、自動車の発進動作や停止動作は、運転席の前下部に並行配置したアクセルペダルとブレーキペダルを操作することで行われる。このように自動車のアクセル動作やブレーキ動作は、加速と減速という相反する制御を並列した２本のフットペダルにより行う構成としているのでアクセルとブレーキの各ペダルの踏み間違いの操作ミスが発生していた。 Conventionally, the start operation and stop operation of an automobile are performed by operating the accelerator pedal and the brake pedal arranged in parallel in the lower front part of the driver's seat. In this way, the accelerator operation and brake operation of the automobile are configured to perform the contradictory controls of acceleration and deceleration by two parallel foot pedals, so that an operation error of pressing each pedal of the accelerator and the brake has occurred. ..

　しかしながら、自動車のアクセルリングの調整操作をしながらも車両の進行方向の操舵をするという同時操作が必要となり、双方同時の操作が必要となった場合はブレーキ操作に集中することが希薄となり緊急の走行停止操作に支障があった。 In the technique of Patent Document 1 described above, it is possible to prevent an erroneous operation in which the accelerator operation and the brake operation are mistakenly operated.
However, it is necessary to perform simultaneous operations such as steering the vehicle in the direction of travel while adjusting the accelerator ring of the vehicle, and if both operations are required at the same time, it is urgent to concentrate on the braking operation. There was a problem with the running stop operation.
　また、特許文献２に記載の技術では、自動車を操舵する円ハンドルと、自動車の操向速度を調整する円ハンドル囲繞のアクセル機構とにより構成しているために同時操作性には優れているが、各ブレーキ操作及びアクセル操作を全て手動で行わなければならないために誤操作が生じやすい。 Further, the technique described in Patent Document 2 is excellent in simultaneous operability because it is composed of a circular handle for steering the automobile and an accelerator mechanism surrounding the circular handle for adjusting the steering speed of the automobile. , Since each brake operation and accelerator operation must be performed manually, erroneous operation is likely to occur.
　本発明は、かかる事情に鑑みてなされた発明であり、ブレーキ操作を取り違えてアクセル操作を行うことがないように構成してアクセル及びブレーキの各操作性に優れた車両操作装置を提供することを目的とする。 The present invention has been made in view of such circumstances, and provides a vehicle operating device having excellent accelerator and brake operability by being configured so that the accelerator operation is not mistaken for the brake operation.

The accelerator rotating body in a gripping form along the peripheral surface of the handle is loosely fitted into the annular grip portion that constitutes a part of the above, and the accelerator rotating body is interlocked and connected to the throttle operation mechanism of the engine, and only the rotation operation of the accelerator rotating body is performed. It is an automobile accelerator device characterized in that the throttle operation mechanism of the engine is operated by the engine.

　本発明の第３の態様は、アクセル回転体をエンジンのスロットル操作機構に連動連結するためのスロットル連結体は、操作ワイヤを介して一端をアクセル回転体に接続すると共に他端をスロットル操作機構に接続したことを特徴とした自動車のアクセル装置である。 In the third aspect of the present invention, the throttle connecting body for interlocking and connecting the accelerator rotating body to the throttle operating mechanism of the engine has one end connected to the accelerator rotating body and the other end to the throttle operating mechanism via an operation wire. It is an automobile accelerator device characterized by being connected.
　本発明の第４の態様は、アクセル回転体をエンジンのスロットル操作機構に連動連結するためのスロットル連結体は、サーボモータ等の電気的作動手段より構成したことを特徴とする自動車のアクセル装置である。 A fourth aspect of the present invention is an automobile accelerator device, wherein the throttle connecting body for interlocking and connecting the accelerator rotating body to the throttle operating mechanism of the engine is composed of an electrically operating means such as a servomotor. be.
　本発明の第５の態様は、円環ハンドルの中心部は、車輪操舵装置に下端部を連結したステアリングシャフトと連動連結すると共に、円環ハンドルのアクセル回転体とエンジンのスロットル操作機構との間に介在したスロットル連動機構は昇降自在のスイベル機構を介して構成したことを特徴とする自動車のアクセル装置である。 In a fifth aspect of the present invention, the central portion of the annular handle is interlocked with the steering shaft whose lower end is connected to the wheel steering device, and between the accelerator rotating body of the annular handle and the throttle operating mechanism of the engine. The throttle interlocking mechanism interposed therein is an automobile accelerator device characterized in that it is configured via a swivel mechanism that can be raised and lowered.
　本発明の第１の態様よれば、自動車のブレーキ操作とアクセル操作が運転手の足と手に分離され、運転中にブレーキ操作とアクセル操作を取り違えるという操作ミスを防止することができる。 According to the first aspect of the present invention, the brake operation and the accelerator operation of the automobile are separated into the driver's foot and the hand, and it is possible to prevent an operation error that the brake operation and the accelerator operation are mistaken for each other during driving.
　本発明の第２の態様によれば、ブレーキ操作と共にアクセル操作が行われるとアクセル回転体は作動前状態に復元してアクセル作動が回避されることになるためにブレーキ操作と間違ってアクセル操作が先行して行われて急発進などの事故を防止することができる。 According to the second aspect of the present invention, when the accelerator operation is performed together with the brake operation, the accelerator rotating body is restored to the pre-operation state and the accelerator operation is avoided, so that the accelerator operation is mistaken for the brake operation.

　以下、本発明の実施の形態について図１～図４を参照して説明する。
　図１は、自動車Ｍのブレーキ操作機構１０を示すブレーキ部と、アクセル操作機構２０を示すハンドル部及びアクセル部の配置を説明するための概要図である。 Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 4.
FIG. 1 is a schematic view for explaining the arrangement of a brake portion showing the brake operation mechanism 10 of the automobile M, and a handle portion and an accelerator portion showing the accelerator operation mechanism 20.
　本発明では、特に従来のフットペダルで構成されたアクセル部を円環ハンドルと一体に配設して、円環ハンドルにハンドル操作とアクセル操作の同時操作を可能に構成したものである。
　すなわち、従来のフットペダルで構成したアクセル部のアクセル操作機構をフットペダルの代りにハンドルの円環グリップ部２２に回転自在に設けたものである。 In the present invention, in particular, the accelerator portion composed of the conventional foot pedal is integrally arranged with the ring handle, and the ring handle is configured to enable simultaneous operation of the handle operation and the accelerator operation.
That is, the accelerator operation mechanism of the accelerator portion composed of the conventional foot pedal is rotatably provided on the ring grip portion 22 of the steering wheel instead of the foot pedal.
　このように、本発明は自動車のブレーキ操作機構とアクセル操作機構を運転手のフット側とハンドル側とに隔離して分離配置することにより、ブレーキ操作とアクセル操作を取り違える誤操作を防止するものである。
　なお、本実施形態の説明においては運転者側から見た方向で説明する。 As described above, the present invention prevents an erroneous operation in which the brake operation and the accelerator operation are mistaken for each other by isolating and separately arranging the brake operation mechanism and the accelerator operation mechanism of the automobile on the foot side and the steering wheel side of the driver. ..
In the description of the present embodiment, the direction seen from the driver side will be described.
　以下に、まず、ブレーキ操作機構１０について詳説する。
　ブレーキ操作機構１０は、図２に示すように、従来の自動車と同様に運転席の床面に設けたブレーキ用フットペダル１１と同ペダルにブレーキ連動機構１２を介して連動連結したブレーキ装置１３とより構成している。 First, the brake operating mechanism 10 will be described in detail below.
As shown in FIG. 2, the brake operation mechanism 10 includes a brake foot pedal 11 provided on the floor surface of the driver's seat and a brake device 13 interlocked with the same pedal via a brake interlocking mechanism 12 as in a conventional automobile. It is composed of more.
　ブレーキ装置１３は、ブレーキ用フットペダル１１の踏み込み操作により車輪１４のブレーキシュー１５を可動して車輪１４のブレーキドラム１６に圧接自在となって、車輪１４の制動操作を行う。 The brake device 13 moves the brake shoe 15 of the wheel 14 by depressing the foot pedal 11 for braking so that it can be pressed against the brake drum 16 of the wheel 14 to perform the braking operation of the wheel 14.
　また、ブレーキ用フットペダル１１は、図３に示すように、後述のスロットル連結体３１にブレーキ連動機構１２を介して連結している。 Further, as shown in FIG. 3, the brake foot pedal 11 is connected to the throttle connecting body 31 described later via the brake interlocking mechanism 12.
　このように構成したブレーキ操作機構１０は、ブレーキ用フットペダル１１が踏み込まれると、ブレーキ連動機構１２を介して車輪１４の制動操作を行う。
　なお、ブレーキ連動機構１２には後述するようにアクセル機構におけるスロットル連結体３１が連動連結されており、車輪停止操作のためにブレーキ連動機構１２を下方に変位作動させると自動的に後述のアクセル回転体２３が強制的に作動前状態に復元するように機能する（図３参照）。すなわち、アクセル作動とブレーキ作動は同時に機能することはなく先にブレーキ作動状態に操作されると自動的にアクセル作動は非作動状態、すなわちアクセル機構の作動前に復元するように制御されてアクセル走行が行えない状態となるように制御される。 When the brake foot pedal 11 is depressed, the brake operation mechanism 10 configured in this way performs a braking operation on the wheels 14 via the brake interlocking mechanism 12.
The brake interlocking mechanism 12 is interlocked with the throttle coupling body 31 in the accelerator mechanism as described later, and when the brake interlocking mechanism 12 is displaced downward for wheel stop operation, the accelerator rotation described later is automatically performed. The body 23 functions to forcibly restore the pre-operation state (see FIG. 3). That is, the accelerator operation and the brake operation do not function at the same time, and if the brake operation state is first operated, the accelerator operation is automatically controlled to be in the non-operation state, that is, to be restored before the accelerator mechanism is activated, and the accelerator travels. Is controlled so that it cannot be performed.
　次に、本発明の要部となるアクセル操作機構２０について図３を参照して詳説する。
　アクセル操作機構２０は、操向用の円環ハンドル２１の一部に円環グリップ部２２を形成している。運転者は、円環グリップ部２２を把持しながら円環ハンドル２１を回転させることにより自動車Ｍの操舵操作を行えるように構成している。 Next, the accelerator operating mechanism 20, which is a main part of the present invention, will be described in detail with reference to FIG.
The accelerator operating mechanism 20 forms an annular grip portion 22 on a part of the annular handle 21 for steering. The driver is configured to be able to steer the automobile M by rotating the ring handle 21 while gripping the ring grip portion 22.
　しかも、円環グリップ部２２は、運転者が円環ハンドル２１を把持して自動車Ｍを操向する把持機能以外にも円環ハンドル２１の周面に沿って配設したアクセル回転体２３の回転構造の一部をなし、このアクセル回転体２３を回転することにより自動車Ｍの走行速度を調整可能とする機能を有している。かかるアクセル回転体２３は、円環ハンドル２１の円環グリップ部２２の周面に遊嵌されてアクセル操作時に回転操作されるように構成されている。 Moreover, the annular grip portion 22 has a gripping function in which the driver grips the annular handle 21 to steer the automobile M, and also rotates the accelerator rotating body 23 arranged along the peripheral surface of the annular handle 21. It forms a part of the structure and has a function of adjusting the traveling speed of the automobile M by rotating the accelerator rotating body 23. The accelerator rotating body 23 is configured to be loosely fitted on the peripheral surface of the annular grip portion 22 of the annular handle 21 so that the accelerator rotating body 23 is rotated during the accelerator operation.
　従って、運転者は、アクセル調整を行うときには、掌で円環グリップ部２２を把持しながら、該グリップ部２２に遊嵌したアクセル回転体２３を回転操作することになる。 Therefore, when adjusting the accelerator, the driver rotates the accelerator rotating body 23 loosely fitted in the grip portion 22 while grasping the annular grip portion 22 with his / her palm.
　かかるアクセル回転体２３は、エンジンのスロットル操作機構３０に連動連結している。従って、エンジンの回転制御は、このアクセル回転体２３を掌で把持する運転者のグリップ操作により行われる。 The accelerator rotating body 23 is interlocked and connected to the throttle operating mechanism 30 of the engine. Therefore, the rotation control of the engine is performed by the grip operation of the driver who grips the accelerator rotating body 23 with his / her palm.
　すなわち、従来、運転者がアクセルフットペダルを足で踏み込む操作によりエンジンのスロットル操作を行っていた構成を、本実施例では円環ハンドル２１に装着したアクセル回転体２３の掌把持形態による回転操作で行う構成とした。 That is, the configuration in which the driver conventionally operates the throttle of the engine by depressing the accelerator foot pedal with his / her foot is changed to the rotation operation of the accelerator rotating body 23 mounted on the annular handle 21 in the palm gripping form in this embodiment. It was configured to be performed.
　このように、運転者の足側の操作は、ブレーキ操作のみに限定されているため急ブレーキを要する緊急の場面にフットブレーキペダルと間違ってアクセル操作を行うという誤操作の危険を人体の手動と足動の機能上の差異に基づく生理的慣習性により確実に回避することができるようにした。 In this way, the driver's foot operation is limited to the brake operation, so there is a risk of erroneous operation of the foot brake pedal and the accelerator operation in an emergency situation where sudden braking is required. Physiological habits based on functional differences in movement have made it possible to avoid them reliably.
　ハンドルは、自動車Ｍの操向制御を行う円環ハンドル２１と、円環ハンドル２１の一部を構成する円環グリップ部２２と、円環グリップ部２２の周面に遊嵌したアクセル回転体２３とにより構成している。 The steering wheel is an annular steering wheel 21 that controls the steering of the automobile M, an annular grip portion 22 that forms a part of the annular handle 21, and an accelerator rotating body 23 that is loosely fitted on the peripheral surface of the annular grip portion 22. It is composed of and.
　アクセル回転体２３によりエンジンのスロットル操作機構３０を作動するためには、両者をワイヤやコード等の紐状体によるスロットル連結体３１で連動連結する。 In order to operate the throttle operation mechanism 30 of the engine by the accelerator rotating body 23, both are interlocked and connected by a throttle connecting body 31 made of a string-like body such as a wire or a cord.
　このようにスロットル連結体３１は、例えば操作ワイヤ３２（図３参照）により構成し、該ワイヤ３２の一端は円環ハンドル２１周面のアクセル回転体２３に接続すると共に、該ワイヤ３２の他端はスロットル操作機構３０の作動部分に連結している。 In this way, the throttle connecting body 31 is composed of, for example, an operation wire 32 (see FIG. 3), and one end of the wire 32 is connected to the accelerator rotating body 23 on the peripheral surface of the annular handle 21 and the other end of the wire 32. Is connected to the operating portion of the throttle operating mechanism 30.
　なお、上記した構成は、操作ワイヤ３２をアクセル回転体２３とスロットル操作機構３０の間に介設した機構的な構造としているが、必ずしも機構的な連動連結構造とする必要もない。 Although the above configuration has a mechanical structure in which the operating wire 32 is interposed between the accelerator rotating body 23 and the throttle operating mechanism 30, it does not necessarily have to be a mechanical interlocking connection structure.
　例えば、アクセル回転体２３の操作に基づくサーボモータの駆動操作機構をサーボモータの出力軸に連動連結したスロットル操作機構３０と連動連結することによりサーボモータをスロットル操作機構３０のアクチュエータとして機能構成するようにしてもよい。 For example, the servomotor can be functionally configured as an actuator of the throttle operation mechanism 30 by interlocking and connecting the drive operation mechanism of the servomotor based on the operation of the accelerator rotating body 23 with the throttle operation mechanism 30 which is interlocked and connected to the output shaft of the servomotor. It may be.
　すなわち、アクセル回転体２３の回転作動により電気的にサーボモータを回転させて該モータの出力軸をエンジンのスロットル操作機構３０の一端に連動連結してスロットルドラム３３を駆動してエンジンへの燃料噴射を制御してエンジンの回転駆動、すなわち、自動車Ｍのアクセル制御をおこなうように構成することができる。 That is, the servomotor is electrically rotated by the rotational operation of the accelerator rotating body 23, the output shaft of the motor is interlocked with one end of the throttle operating mechanism 30 of the engine, and the throttle drum 33 is driven to inject fuel into the engine. It can be configured to control the rotation of the engine, that is, to control the accelerator of the automobile M.
　円環ハンドル２１は、図１に示すように、リム中心部をステアリングシャフト４１と連結して円環ハンドル２１の操舵作動にともなってステアリングシャフト４１を回動して車輪操舵装置４０の駆動を行うように構成している。 As shown in FIG. 1, the annular handle 21 connects the central portion of the rim to the steering shaft 41 and rotates the steering shaft 41 in accordance with the steering operation of the annular handle 21 to drive the wheel steering device 40. It is configured as follows.
　車輪操舵装置４０は、ステアリングシャフト４１に連結したステアリングギアボックス４２と、ステアリングギアボックス４２から左右の車輪側に延設したタイロッド４３と、車輪１４に連結したナックルアームにより構成している。 The wheel steering device 40 includes a steering gear box 42 connected to the steering shaft 41, a tie rod 43 extending from the steering gear box 42 to the left and right wheels, and a knuckle arm connected to the wheels 14.
　ステアリングギアボックス４２は、ステアリングシャフト４１の下端部に連結したステアリングピニオンギアと、ステアリングピニオンギアに噛合したステアリングラックギアとにより構成している。また、ステアリングラックギアの左右には、タイロッド４３を連結しており、該ロッド４３の一端部が車輪１４に連結したナックルアームに連結している。 The steering gear box 42 is composed of a steering pinion gear connected to the lower end of the steering shaft 41 and a steering rack gear meshed with the steering pinion gear. Further, tie rods 43 are connected to the left and right sides of the steering rack gear, and one end of the rod 43 is connected to a knuckle arm connected to the wheel 14.
　このように、車輪操舵装置４０は構成されており、円環ハンドル２１の操向操作を左右の車輪１４、１４に伝達できるように構成している。
　すなわち、円環ハンドル２１による自動車Ｍの操向操作は、ステアリングシャフト４１を介してステアリングギアボックス４２を構成するステアリングピニオンギアに伝達され、ステアリングピニオンギアと噛合したステアリングラックギアの左右への動きに連動して自動車Ｍの車輪１４の操舵角を調整できる。 In this way, the wheel steering device 40 is configured so that the steering operation of the annular handle 21 can be transmitted to the left and right wheels 14, 14.
That is, the steering operation of the automobile M by the annular handle 21 is transmitted to the steering pinion gear constituting the steering gear box 42 via the steering shaft 41, and is linked to the left and right movement of the steering rack gear meshed with the steering pinion gear. Then, the steering angle of the wheel 14 of the automobile M can be adjusted.
　従って、操舵のための円環ハンドル２１の回転操作は、ステアリングシャフト４１を介して車輪操舵装置４０に伝導される。
　円環ハンドル２１の一部を構成した円環グリップ部２２には、アクセル回転体２３が把持状態で回動自在に装着されており、しかも、アクセル回転体２３に連結した操作ワイヤ３２はステアリングシャフト４１の中心部を垂下してステアリングシャフト４１下方にまで伸延してスロットル操作機構３０に連動連結されている。 Therefore, the rotational operation of the annular handle 21 for steering is conducted to the wheel steering device 40 via the steering shaft 41.
The accelerator rotating body 23 is rotatably attached to the annular grip portion 22 which forms a part of the annular handle 21, and the operation wire 32 connected to the accelerator rotating body 23 is a steering shaft. The central portion of 41 is hung down and extended to the lower side of the steering shaft 41, and is interlocked and connected to the throttle operation mechanism 30.
　アクセル回転体２３の周面部に一端を固定したワイヤ等のスロットル連結体３１は、他端を中空のステアリングシャフト４１内を挿通して最終端部は、スロットル操作機構３０に連動連結している。 The throttle connecting body 31 such as a wire having one end fixed to the peripheral surface of the accelerator rotating body 23 is inserted through the hollow steering shaft 41 at the other end, and the final end is interlocked with the throttle operating mechanism 30.
　アクセル回転体２３の回転作動は、スロットル操作機構３０に連動連結されているために、操舵のための円環ハンドル２１の回転操作を行うとアクセル回転体２３から伸延する操作ワイヤ３２などのスロットル連結体３１が捩じれる。従って、操作ワイヤ３２などのスロットル連結体３１の中間位置にスイベル機構４７を介在することによりワイヤ等の捩じれを吸収してアクセル回転体２３の回転操作をスロットル操作機構３０に支障なく伝えることができる。スイベル機構４４はアクセル回転体２３から伸延する操作ワイヤ３２などのスロットル連結体３１がアクセル回転体２３の回転操作により緊張弛緩するために回転自在の機能とともに上下昇降自在に構成されていることが必要となる。 Since the rotational operation of the accelerator rotating body 23 is interlocked with the throttle operating mechanism 30, the throttle connecting of the operation wire 32 extending from the accelerator rotating body 23 when the rotating operation of the annular handle 21 for steering is performed. The body 31 is twisted. Therefore, by interposing the swivel mechanism 47 at the intermediate position of the throttle connecting body 31 such as the operation wire 32, it is possible to absorb the twist of the wire or the like and transmit the rotation operation of the accelerator rotating body 23 to the throttle operating mechanism 30 without any trouble. .. The swivel mechanism 44 needs to be configured so that the throttle connecting body 31 such as the operation wire 32 extending from the accelerator rotating body 23 can be moved up and down with a rotatable function in order to relax the tension by the rotating operation of the accelerator rotating body 23. It becomes.
