Abstract
【解決手段】ブレーキ装置7は、ブレーキ本体と、ブレーキレバー20の操作に連動して切換えられるブレーキスイッチ22とを有し、ブレーキレバー20を操作していない開放位置Aとブレーキ本体が作動する作動開始位置Cとの間の遊びの範囲S1内に、ブレーキスイッチ22のオン・オフが切換えられるスイッチ切換位置Bが設定される。そして、ブレーキスイッチ22がオンに切換えられることで補助駆動力の付与機能が停止され、ブレーキレバー50が操作されて開放位置Aからスイッチ切換位置Bに達し、ブレーキスイッチ22がオフからオンに切換えられると、バッテリの残量表示灯とモード表示灯との輝度が増大する。
【選択図】図5
Description
図1に示すように、1は電動自転車であり、フレーム2と、前車輪3および後車輪4と、ハンドル5と、ペダル6と、機械式の前および後ブレーキ装置7,8(図3、図4参照)と、補助駆動力(アシスト力)を発生させる電動モータ9と、電動モータ9に駆動用の電力を供給する二次電池からなるバッテリ10と、ライト(前照灯)11と、操作盤12等が設けられている。
上記構成において、例えば、電動自転車1を出荷する前の調整工程において、作業者が電源ボタン14を押してオンにすると(ステップ−1)、主電源が入って制御装置28が起動する(ステップ−2)。
また、上記実施の形態においては、電動自転車1の走行速度にかかわらず、ブレーキスイッチ22,27の切換えにより補助駆動力の発生が停止されるよう構成したが、これに限るものではない。すなわち、図10に示すように、速度検知手段としての速度センサ37からの走行速度情報に基づいて(ステップ−6)、走行速度が所定速度(例えば、時速5km)を越えた中高速である場合には、ブレーキスイッチ22,27の切換えによる補助駆動力の発生の停止を行わず(すなわち補助駆動力の発生可能状態を維持し)(ステップ−4)、走行速度が0または所定速度(例えば、時速5km)以下の低速である場合に、ブレーキスイッチ22,27の切換えにより補助駆動力の発生が停止されるよう(ステップ−5)構成してもよい。
