Abstract
【解決手段】作業車両の制御部は、トランスミッション要求決定部と、指令トルク決定部と、牽引力制限部とを有する。トランスミッション要求決定部は、アクセル操作部材の操作量に基づいて要求牽引力を決定する。要求牽引力は、走行装置での目標牽引力である。指令トルク決定部は、車両の牽引力が要求牽引力となるように電動モータの出力トルクを決定する。牽引力制限部は、車両が掘削中であるときには、要求牽引力をアクセル操作部材の操作量に応じた値よりも低減する。

Ts1_Low = Te_ref * r_fr
Tc1_Low = Ts1_Low * (-1) * ( (Zr1/Zs1) + 1 )
Tr2_Low = To_ref * (Zod/Zo)
Ts2_Low = Tr2_Low * (Zs2/Zr2)
Tcp1_Low = Tc1_Low + Ts2_Low
Tm1_Low = Tcp1_Low * (-1) * (Zp1/Zp1d)
Tr1_Low = Ts1_Low * (Zr1/Zs1)
Tm2_Low = Tr1_Low * (-1) * (Zp2/Zp2d)
また、指令トルク決定部83は、以下の数2に示す第2のトルクバランス情報を用いてHiモードでのモータMG1, MG2への指令トルクTm1_Hi,Tm2_ Hiを決定する。本実施形態において、第2のトルクバランス情報は、動力伝達装置24でのトルクの釣り合いの式である。
