Abstract
Description
図6は、図5に示す第1回路61及び第2回路62の等価回路図である。抵抗R1の値を24kΩ、抵抗R2の値を8.2kΩとしている。第1グランド部GND1における断線は、ハイサイドスイッチ108をオンして第1電圧と第2電圧を比較することで検知可能である。
BAT2_MON1は、第1グランド部GND1を基準とした電圧である。電線612Gが断線した場合、第1回路61から第2回路62に電流が流れる経路が形成され、第1グランド部GND1の電圧が、第2グランド部GND2の電圧に対し浮く(上昇する)。BAT2電圧から、第1グランド部GND1が浮いた分(図中に示すV_float)電圧を引いた電圧を、2つの抵抗R3,R4で分圧した電圧がBAT2_MON1端子に入力される。この電圧をソフトウェアで抵抗R3,R4で分圧する前の電圧に逆算すると、BAT2電圧が、第1グランド部GND1が浮いた分(図中に示すV_float:2V)だけ低い値に計算される。
BAT2_MON1とBAT2_MON2の計算値の差異が第1グランド部GND1の浮量の2.9倍となる。即ち、V_floatが例えば2Vの場合、2.9倍の約6Vになる。
したがって、BAT2_MON1とBAT2_MON2の計算値の差異が例えば1.5V以上、または3V以上などとなっていれば、第1グランド部GND1において断線が生じたと判定できる。即ち、電線612Gが断線した、又は、電池60との接続部分で断線した、又は、第1コネクタ部64との接続部分で断線したことを判定できる。
BAT2_MON1=(Vbat2-V_float)……(1)
BAT2_MON2=(Vbat2×R2/(R1+R2)-V_float)×(R1+R2)/R2
=Vbat2-(1+R1/R2)×V_float……(2)
(1)-(2)=(R1/R2)×V_float(=2.9×V_float)
