To build a control structure which, even when first and second torque devices different in responsiveness are included, appropriately determines manipulated variables while satisfying a plurality of constraint conditions and suppressing increase in an amount of calculation, and which has high versatility.SOLUTION: A powertrain system includes a first torque device, a second torque device having a larger response delay than the first torque device, and a control device. The control device includes: a manipulated variable determination section which solves a linear programming problem, thereby determining and outputting manipulated variables maximally achieving target state quantities within a range where a plurality of constraint conditions is satisfied; and a torque device control section which controls the first and second torque devices in accordance with the output manipulated variables. The plurality of constraint conditions includes a maximum value and a minimum value of a second manipulated variable which can be reached at a next time step, as the upper and lower limit constraint values of the second manipulated variable. The control device further includes a manipulated variable upper and lower limit calculation section which calculates the maximum value and the minimum value as the upper and lower limit constraint values on the basis of a current revolution speed and estimated manipulated variable of the second torque device.SELECTED DRAWING: Figure 1

    【課題】応答性の異なる第1及び第2トルクデバイスを備える場合であっても、複数の制約条件を満たしつつ操作量を演算量の増加を抑制しつつ適切に決定し、かつ汎用性の高い制御構造を構築する。【解決手段】パワートレーンシステムは、第1トルクデバイスとこれより応答遅れの大きな第2トルクデバイスと制御装置とを備える。制御装置は、複数の制約条件を満たす範囲内で目標状態量を最大限実現する操作量を、線形計画問題を解くことにより決定して出力する操作量決定部と、出力された操作量に従って第1及び第2トルクデバイスを制御するトルクデバイス制御部とを含む。複数の制約条件は、次の時間ステップにおいて到達可能な第2操作量の最大値及び最小値を第2操作量の上下限制約値として含む。制御装置は、現在の第2トルクデバイスの回転数及び推定操作量に基づいて、上記の最大値及び最小値を上下限制約値として算出する操作量上下限算出部をさらに含む。【選択図】図1
