To provide a speed change control device of a hybrid vehicle that can reduce a speed change time during which a predetermined engagement clutch is released therefrom, then the number of input rotation is changed and the other engagement clutch is engaged therewith.SOLUTION: The speed change control device of a hybrid vehicle comprises an engine, a motor, and a speed change mechanism whose input shaft is connected with the engine and the motor, performs speed change by performing unloading-control by which input torque to a releasing-side engagement mechanism of the speed change mechanism and synchronization control by which a difference between the number of input rotation and the number of output rotation of an engagement-side engagement mechanism of the speed change mechanism is synchronized with a predetermined difference or less, which is configured to set control motor torque at the time of the unloading control to limit torque or less determined by reducing torque required for the motor in order to keep the difference between the number of input rotation and the number of output rotation at the predetermined difference or smaller while maintaining engine torque at predetermined torque during the synchronization control, from predetermined upper limit torque (a step S5).SELECTED DRAWING: Figure 2
【課題】所定の噛み合いクラッチを解放した後に、入力回転数を変化させて他の噛み合いクラッチを係合させる変速時間を短縮することができるハイブリッド車両の変速制御装置を提供する。【解決手段】エンジンと、モータと、エンジンおよびモータが入力軸に連結された変速機構とを備え、変速機構の解放側係合機構への入力トルクを低下させる抜重制御と、変速機構の係合側係合機構の入力回転数と出力回転数との差を所定差以下に同期させる同期制御とを行うことにより変速を行うハイブリッド車両の変速制御装置において、抜重制御時におけるモータトルクを、予め定められた上限トルクから同期制御時にエンジントルクを所定トルクに維持した状態で入力回転数と出力回転数との差を所定差以下にするためにモータに要求されるトルクを減算した制限トルク以下に制御するように構成されている(ステップS5)。【選択図】図2
