Description
本願は、ここに引用により援用される、2007年9月21日に出願された米国仮特許出願連続番号第60/974,206号、および2008年9月16日に出願された米国特許出願連続番号第12/211,360号の優先権を主張する。
I.発明の分野
この発明は一般に位置センサに関し、より特定的には誘導式位置センサに関する。
自動車車両では、スロットルペダルは伝統的に、ケーブルによってエンジンスロットルに機械的に接続されてきた。しかしながら、より近代的な車両では、スロットル位置センサがペダルに機械的に接続され、スロットルペダルの踏み込み度合を示す電気出力信号を生成する。そのようなシステムはしばしば、「フライ・バイ・ワイヤ」(fly-by-wire)システムと呼ばれる。
この発明は、以前から公知のスロットル位置センサの上述の欠点を克服するスロットル位置センサを提供する。
この発明のより良好な理解は、以下の詳細な説明を添付図面とともに読むことで得られるであろう。いくつかの図全体を通し、同じ参照番号は同じ部分を示す。
最初に図1を参照すると、わかりやすくするために、スロットル位置センサ10の部品が取外された状態で、スロットル位置センサ10の一部が示されている。スロットル位置センサ10はプリント回路基板12を含み、それは通常、汚染物質および/または他の損傷からプリント基板12を保護するハウジング15(図4)内に収容されている。
