PROBLEM TO BE SOLVED: To provide a vehicle shift position detection device which has at least four sensors and enables a vehicle to perform evacuation travel while preventing improper forward or backward gear change operation.SOLUTION: A vehicle shift position detection device can reliably prevent improper forward or backward gear change operation in a manner that: maintains vehicle travel, even when one Hall IC fails, with a shift position Psh which can be decided by remaining three Hall ICs; and switches the shift position Psh to a neutral range when determining abnormality where any two Hall ICs among the remaining three Hall ICs output signals indicating that the shift position Psh is switched to a travel direction opposite to a current shift range. Thus, the vehicle shift position detection device enables a vehicle to perform safe evacuation travel on the basis of three Hall ICs.SELECTED DRAWING: Figure 9

    【課題】少なくとも4個のセンサから成るシフト位置検出装置について、前後進切替の誤作動を回避しつつ退避走行できる車両用シフト位置検出装置を提供する。【解決手段】1つのホールICが故障しても3個のホールICによって決定されるシフト位置Pshに基づいて走行が継続され、この3個のホールICのうち何れか2つが、現在のシフトレンジと逆方向に走行するシフト位置Pshへの信号を出力した場合に異常であると判定されて、ニュートラルレンジに切り替えられるため、前後進の誤作動が確実に防止される。従って、3個のホールICに基づいて安全な退避走行が可能となる。【選択図】図9
