Description
この場合、変速制御の指令ギヤ比kgear(1)と実ギヤ比kgear(2)とは、ほぼ等しい。そのため、kgear(1)<{kgear(2)/α}もkgear(1)<{kgear(2)−β}も成立しない(S300にてNO)。
この場合、変速制御の指令ギヤ比kgear(1)と実ギヤ比kgear(2)とは、等しくなくなり大きく乖離する。そのため、kgear(1)<{kgear(2)/α}またはkgear(1)<{kgear(2)−β}が成立する(S300にてYES)。なお、ここでは、指令ギヤ比kgear(1)に対して実ギヤ比kgear(2)が低ギヤ段(大ギヤ比)側にしかならないフェールの発生を想定している。
このため、自動変速機の入力軸回転数や出力軸回転数の変動の影響や回転数を検知するセンサの精度の影響を考慮しなくて済む指令ギヤ比kgear(1)、およびフェール時においても実際のギヤ比でガードが可能な実ギヤ比kgear(2)のいずれかの大きい方の変速比が演算用変速比に代入される(S500)。
