Description
図1に示すように、電動二輪車1は、従動輪である前輪2と駆動輪である後輪3とを備えている。前輪2は、フロントフォーク4の下端部に回転自在に支持されており、フロントフォーク4の上部は上下一対のブラケット4a,4bを介してステアリング軸(図示せず)に支持されている。そのステアリング軸は車体側のヘッドパイプ5に内挿された状態で回転自在に支持されており、上側のブラケット4bには左右へ延びるバー型のハンドル6が取り付けられている。ハンドル6の右側には運転者の右手により把持されて、手首のひねりによって回転するアクセルグリップ7が設けられ、そのアクセルグリップ7の前側にはブレーキ操作子8(ブレーキレバー)が設けられている。
本実施形態の電動二輪車1には、電動モータ18とギヤ列39との間を遮断するクラッチ機構が設けられていないが、それらの間にクラッチ機構を設けてもよい。また、本実施形態の電動二輪車1では、変速段位、変速操作、係合の有無、シフト方向等を検出したり推定したりするためにシフトドラムポテンショメータ21が設けられているが、必ずしもシフトドラムポテンショメータ21である必要はない。例えば、ドッグギヤ35と出力側歯車39bとが噛み合うギヤポジションだけを検出できるギヤポジションセンサであってもよい。この場合、係合の有無は、入力軸31と出力軸34との回転数比によって推定される。即ち、入力軸31と出力軸34との回転数の比が選択されている変速段位の回転数比と略同一の場合、ドッグギヤ35と出力側歯車39bとが係合状態にあると判定され、それ以外の場合、ドッグギヤ35と出力側歯車39bとが非係合状態にあると判定される。

前記制御装置は、前記第2制御において、前記変速段位検出装置及び前記変速指令検出装置の検出結果に基づいて変速操作により切替えられる変速段位を推定し、推定する変速段位に応じた増速回転数で入力軸が回転するように前記電動機の動きを制御する、
請求項1又は2に記載の電動車両。 - 前記変速操作検出装置は、シフトドラムの角度位置を検出する角度検出部を有し、
前記シフトドラムは、予め定められる角度位置毎に定められた変速段位の変速ギヤ列を係合させ、
前記制御装置は、予め定められる角度位置を中心とする不感帯域が変速段位毎に設定され、前記シフトドラムの角度位置が不感帯域の範囲内にあると前記変速操作の無しと判定し、前記シフトドラムの角度位置が不感帯域の範囲外であると前記変速操作の有りと判定する、請求項2に記載の電動車両。 - 運転者による操作子の変速操作に応じて回転比を切替え、且つ切替られた回転比で電動機のトルクを駆動輪に伝達する常時噛合い式の変速装置を備える電動車両の変速制御方法であって、
運転者による変速操作の有無を判定する判定工程と、
前記判定工程において前記変速操作があったと判定すると、前記電動機の動作を制御する第1制御工程と、
前記第1制御工程の後で、前記電動機の動作を制御してドッグの回転数を変速後に噛合すべき変速ギヤ列の回転数に近づくようにする第2制御工程とを有する、
第1制御工程では、該第1制御工程前における前記電動機のトルクの方向と反対方向の解除トルクを前記電動機に発生させて前記ドッグを係合する前記変速ギヤ列から離す、電動車両の変速制御方法。
