FIG. 4 is a block diagram showing the configuration of the accelerator device according to this embodiment. An operation amount of an accelerator lever 24 as an auxiliary accelerator operator, a vehicle speed obtained by a vehicle speed sensor 50, and a representative engine temperature obtained by an oil temperature sensor 51 are input to the ECU 40 as a control unit.
スロットルボディ７１には、本体部７３に形成された吸気通路７２の断面積を変更して燃焼室内への吸気量を調整するスロットルバルブ７４が揺動自在に収納されている。一方、スロットルボディ７１には、アイドリング運転用のバイパス通路７７が設けられており、調整弁としてのアイドルエアコントロールバルブ７８を開くことにより、冷間時のアイドリング運転をスムーズに行うことが可能とされる。アイドルエアコントロールバルブ７８は、車速センサ５０および油温センサ５１の出力に応じてアクチュエータ７９によって自動的に開くと共に、パワーユニットの暖気運転が終了して、安定的にアイドリング運転が継続される状態となると自動的に閉じるように構成されている。調整弁は、電磁弁やステッピングモータ等で駆動する電動式とされる。
A throttle valve 74 that adjusts the amount of intake air into the combustion chamber by changing the cross-sectional area of an intake passage 72 formed in the body portion 73 is housed in the throttle body 71 so as to be swingable. On the other hand, the throttle body 71 is provided with a bypass passage 77 for idling operation, and by opening an idle air control valve 78 as a regulating valve, it is possible to perform idling operation smoothly when cold. be. The idle air control valve 78 is automatically opened by the actuator 79 according to the outputs of the vehicle speed sensor 50 and the oil temperature sensor 51, and when the warm-up operation of the power unit ends and the idling operation is stably continued. Configured to close automatically. The regulating valve is an electric type that is driven by a solenoid valve, a stepping motor, or the like.
本実施形態では、アクセルレバー２４の操作に応じてアイドルエアコントロールバルブ７８を任意に作動させることにより、１０ｋｍ／ｈ以下の低速域で加速操作が可能となるように構成されている点に特徴がある。
This embodiment is characterized in that the idle air control valve 78 is arbitrarily operated in accordance with the operation of the accelerator lever 24, thereby enabling acceleration operation in a low speed range of 10 km/h or less. be.
本実施形態では、アクセルレバー２４は補助アクセル操作子であり、車速が所定車速（例えば、１０ｋｍ／ｈ）以下の場合に有効な加速が可能で、所定車速を超えると加速が弱くなるように設定されている。本実施形態では、所定車速を超えている場合はアクセルレバー２４を操作してもパワーユニットＰの出力の増加度合がゼロとなり、自動二輪車１が加速しないように設定されている。
In this embodiment, the accelerator lever 24 is an auxiliary accelerator operator, and is set so that effective acceleration is possible when the vehicle speed is below a predetermined vehicle speed (eg, 10 km/h), and acceleration becomes weaker when the vehicle speed exceeds the predetermined vehicle speed. It is In this embodiment, when the vehicle speed exceeds a predetermined speed, even if the accelerator lever 24 is operated, the degree of increase in the output of the power unit P becomes zero, and the motorcycle 1 is set so as not to accelerate.
一方、通常の加速操作は、運転者Ｒが右足で操作するアクセルペダル３０によってスロットルボディ７１のスロットルバルブ７４を作動させて行うように構成されている。これにより、地面に足を着きたい低速領域において、右手でアクセル操作が実行可能であるため、アクセル操作と足着き動作との両立が可能となる。
On the other hand, normal acceleration operation is performed by operating the throttle valve 74 of the throttle body 71 with the accelerator pedal 30 operated by the driver R with his right foot. As a result, it is possible to operate the accelerator with the right hand in a low-speed region where the user wants to touch the ground, and thus it is possible to perform both the accelerator operation and the foot-on motion.
また、所定車速を超えるとアクセルレバー２４の操作に伴う出力の増加度合が小さくなるため、アクセルペダルの操作を促して、ブレーキ操作とアクセル操作とを分けることが可能となる。なお、所定車速を超えた場合にパワーユニットＰの出力の増加度合をゼロとするのではなく、わずかに加速するように設定してもよい。また、アクセルレバー２４の操作に伴う出力の増加度合は、所定車速に達した時点で切り替わるのではなく、所定車速に近づくにつれて徐々に小さくなるように、または、所定車速をまたいで徐々に小さくなるように設定することができる。
In addition, when the vehicle speed exceeds a predetermined speed, the degree of increase in the output accompanying the operation of the accelerator lever 24 decreases, so that it is possible to separate the brake operation from the accelerator operation by prompting the operation of the accelerator pedal. It should be noted that the degree of increase in the output of the power unit P may not be set to zero when the vehicle speed exceeds the predetermined vehicle speed, but may be set to slightly accelerate. Further, the degree of increase in the output accompanying the operation of the accelerator lever 24 does not switch when the vehicle speed reaches a predetermined speed, but gradually decreases as the vehicle speed approaches the predetermined vehicle speed, or gradually decreases across the predetermined vehicle speed. can be set as
また、ＥＣＵ４０は、アクセルレバー２４の操作に応じて、モータＭを駆動できるように構成されている。前記したように、動力源としてのモータＭは、内燃機関の始動および発電を行う機能に加えて、低速時の駆動力を発生することが可能とされる。これにより、低速領域において、アクセルレバー２４の操作に応じて、モータＭを駆動して自動二輪車１を加速させることが可能となる。モータＭによって加速させる場合も、所定車速以下の場合より所定車速を超えている場合の方がアクセルレバー２４の操作に対する出力の増加度合が小さくなるように設定される。
Further, the ECU 40 is configured to drive the motor M according to the operation of the accelerator lever 24 . As described above, the motor M as a power source can generate driving force at low speed in addition to the functions of starting the internal combustion engine and generating electricity. As a result, it is possible to drive the motor M and accelerate the motorcycle 1 in the low speed range in accordance with the operation of the accelerator lever 24 . When the vehicle is accelerated by the motor M, it is set so that the degree of increase in the output corresponding to the operation of the accelerator lever 24 is smaller when the vehicle speed exceeds the predetermined vehicle speed than when the vehicle speed is below the predetermined vehicle speed.
なお、自動二輪車の形態、アクセルペダルの形状や構造、アクセルレバーの形状や構造等は、上記実施形態に限られず、種々の変更が可能である。例えば、アクセルレバーは、人差し指で操作するレバーや人差し指と親指で回動させるダイヤル等の種々の構造とするほか、補助アクセル操作子としてアクセルグリップを備えてもよい。また、アクセルレバーが機能する所定車速は、１０ｋｍ／ｈの固定値とするほか、状況に応じて１０ｋｍ／ｈ以下の範囲内で可変する設定としてもよい。また、本実施形態に係るアクセルレバーは、アクセルバイワイヤを備えた車両にも適用することができ、アクセルレバーの操作に応じて作動させるのは、アイドルエアコントロールバルブやモータのほか、スロットルバルブそのものであってもよい。さらに、モータは、電動車両やハイブリッド車両における駆動用モータのほか、内燃機関に設けられるスタータモータであってもよい。所定車速は、運転者が足を地面側に出さなくても安心して運転できる速度よりも速い速度であって、且つできるだけ低い速度に設定されるのが良く、本明細書では一例として１０ｋｍ／ｈとしている。本発明に係る補助アクセル操作子は、自動二輪車に限られず、鞍乗型の三輪車や四輪車等に適用することが可能である。
It should be noted that the form of the motorcycle, the shape and structure of the accelerator pedal, the shape and structure of the accelerator lever, etc. are not limited to the above embodiments, and various modifications are possible. For example, the accelerator lever may have various structures such as a lever operated by the index finger or a dial rotated by the index finger and thumb, and may be provided with an accelerator grip as an auxiliary accelerator operator. Moreover, the predetermined vehicle speed at which the accelerator lever functions may be set to a fixed value of 10 km/h, or may be set to be variable within a range of 10 km/h or less depending on the situation. In addition, the accelerator lever according to the present embodiment can also be applied to a vehicle equipped with an accelerator-by-wire system, and the throttle valve itself, in addition to the idle air control valve and the motor, can be operated according to the operation of the accelerator lever. There may be. Furthermore, the motor may be a drive motor for an electric vehicle or a hybrid vehicle, or a starter motor provided for an internal combustion engine. The predetermined vehicle speed is preferably set to a speed that is faster than the speed at which the driver can safely drive the vehicle without putting his feet on the ground, and is set to a speed as low as possible. and The auxiliary accelerator operator according to the present invention can be applied not only to motorcycles, but also to straddle-type three-wheeled vehicles, four-wheeled vehicles, and the like.
