図2は、本発明の実施形態に係るドア開閉制御部1の構成を示すブロック図である。ドア開閉制御部1は、ドア51の開閉を指令するコントローラ25からの指令に基づいて電動モータ13の回転位置を制御することにより、ドア51の開閉位置を制御するように構成されている。ドア開閉制御部1は、電源電圧検出部2と、基準電圧指令パターン記憶部3(基準制御パターン記憶部)と、PWM制御部4と、ホール信号検出部5と、モータ駆動部6と、を備えている。
図7は、ドア開閉制御部1の動作を説明するためのフローチャートである。図7を参照して、ドア51の閉動作について説明する。なお、ドア51の開動作については、以下で説明するステップS3のドア閉指令がドア開指令に置き換わり、ステップS6のドア閉動作がドア開動作に置き換わったものであり、その他の動作については図7と同じであるため、説明を省略する。
以上のように、本実施形態に係るドア開閉制御部1では、PWM制御部4は、電動モータを制御する。具体的には、PWM制御部4は、電動モータ13に印加される電圧のデューティー比を電圧指令パターンに基づいて制御する。そして、モータ駆動部6は、PWM制御部4によって制御されるデューティー比に基づいて、電動モータ13を駆動する。このように、電動モータ13に入力される電力を調整することで、該電動モータ13の挙動を制御することができる。
