Description
ここで、Tepcmはエンジン120からエンジントルク要求値Teが出力された場合のエンジン直行トルク値(エンジン120から動力分割機構200を経由して出力軸220に伝達されるトルク値)である。すなわち、クリープトルク要求値Tpは、エンジン直行トルク値TepcmとMG(2)トルク要求値Tm2との和である。
MG(2)トルク算出部8250は、クリープトルク要求値Tp(=Td0×Kcrp)およびエンジントルク要求値Teを上記の式(2)に代入して、MG(2)トルク要求値Tm2を算出する。すなわち、MG(2)トルク算出部8250は、クリープトルク要求値Tpからエンジン直行トルク値Tepcmを除いた残余のトルクをMG(2)トルク要求値Tm2として算出する。このような算出手法から明らかなように、クリープトルク要求値Tpを一定とした場合、エンジントルク要求値Teが大きいほど、MG(2)トルク要求値Tm2が小さい値として算出される。また、クリープトルク要求値Tp<Tepcmとなる場合には、MG(2)トルク要求値Tm2は負の値として算出される場合もある。
