Description
図1は、本実施の形態における電動アシスト車の一例である電動アシスト自転車の一例を示す外観図である。この電動アシスト自転車1は、モータ駆動装置を搭載している。モータ駆動装置は、バッテリパック101と、モータ駆動制御装置102と、トルクセンサ103と、ペダル回転センサ104と、モータ105と、操作パネル106と、ブレーキセンサ107とを有する。
第1の実施の形態では、ΔVと回生係数との対応関係を予め定めておき、現在のΔVに対応する回生係数を特定するようにしていたが、加速度と回生係数との対応関係を予め定めておき、現在の加速度に対応する回生係数を特定するようにしても良い。
第1の実施の形態及びその変形では、ブレーキセンサ107を用いてユーザによるブレーキ操作を把握していたが、ブレーキセンサ107の分だけコストが増加する。本実施の形態では、ブレーキセンサ107を用いないでブレーキ操作を推定する場合の処理について説明する。
例えば、図13の処理については、図17に示すような処理に変更するようにしても良い。
第2の実施の形態においても図6を用いるような例を示したが、図10を代わりに用いるようにしてもよい。
第2の実施の形態では、ブレーキセンサ107を用いない例を説明したが、ブレーキセンサ107を他の目的などで設ける場合には、当該ブレーキセンサ107からの出力を用いるように変形しても良い。
上で述べた実施の形態では、基準速度に基づき回生係数を決定する回生制御を、第3フラグがOFFにセットされるまで行うようにしていたが、第3フラグがOFFにセットされなくても、1回のブレーキ操作の影響をフェードアウトさせるようにしてよい。
