PROBLEM TO BE SOLVED: To suppress discomfort on the part of a driver due to a shift shock and the like when shifting in a mechanical stepped transmission part in the case of including an electrical stepless transmission and the mechanical stepped transmission part.SOLUTION: During a simultaneous shift in which shift control of a simulation gear stage is different from shift control of a mechanical gear stage, a shift instruction output for the simulation gear stage is delayed so that both of the shifts are synchronously executed, and therefore both of the shifts are synchronously performed regardless of a difference in shift response time Rei, Rem, thus suppressing discomfort given to a driver due to a shift shock and the like. That is, if shift instructions for both of them are simultaneously output, a change in engine revolution speeds Ne (an inertia phase) in association with a shift in the electrical stepless transmission part is advanced from a change in output shaft torque due to a change in MG2 rotation speed Nm (an inertia phase) in association with a shift in the mechanical stepped transmission part, as indicated by a dotted line in the column of the engine revolution speed Ne, resulting in possibility of causing discomfort on the part of the driver.SELECTED DRAWING: Figure 10

    【課題】電気式無段変速部および機械式有段変速部を有する場合に、機械式有段変速部の変速時に変速ショックなどで運転者に生じさせる違和感を抑制する。【解決手段】模擬ギヤ段の変速制御がメカギヤ段の変速制御と重なる同時変速時に、両者の変速が同期して行なわれるように模擬ギヤ段の変速指令出力が遅延させられるため、変速応答時間REi、REmの相違に拘らず両者の変速が同期して行なわれるようになり、変速ショック等により運転者に与える違和感が抑制される。すなわち、両者の変速指令が同時に出力されると、エンジン回転速度Neの欄に一点鎖線で示すように、電気式無段変速部の変速に伴うエンジン回転速度Neの変化(イナーシャ相)が、機械式有段変速部の変速に伴うMG2回転速度Nmの変化(イナーシャ相)による出力軸トルクの変化よりも早くなり、運転者に違和感を生じさせる可能性がある。【選択図】図10
