PROBLEM TO BE SOLVED: To suppress an incongruity imparted to a driver due to a gear change shock or the like at a gear change of a mechanical stepped gear change part when a gear change control device has an electric stepless gear change part and the mechanical stepped gear change part.SOLUTION: At a simultaneous gear change at which the gear change control of a simulated gear stage is superimposed on the gear change control of a mechanical gear stage, a gear change command output of the simulated gear stage is delayed so that both the gear changes are synchronously performed, both the gear changes are thereby synchronously performed irrespective of a difference of gear change response times, and thus an incongruity imparted to a driver caused by a gear change shock or the like can be suppressed. Furthermore, when the simulated gear stage is singly gear-changed, since a gear change command is outputted after the lapse of a single gear change delay time DEL2, a gear change necessary time from gear change determination becomes substantially the same as a gear change necessary time at the simultaneous gear change, also becomes substantially the same irrespective of a single gear change or a simultaneous gear change of a gear change necessary time after a gear change requirement of a driver up to an inertia phase start at a manual gear change mode, and thus the incongruity imparted to the driver caused by the difference of the gear change necessary times can be suppressed.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。また、模擬ギヤ段を単独で変速する場合には、単独変速用遅延時間DEL2を経過した後に変速指令を出力するため、その変速判断からの変速所要時間が同時変速の場合の変速所要時間と略同じになり、手動変速モードの際に、運転者の変速要求からイナーシャ相開始までの変速所要時間が単独変速か同時変速かに拘らず略同じになり、その変速所要時間の相違によって運転者に違和感を与えることが抑制される。【選択図】図10
