PROBLEM TO BE SOLVED: To provide a speed change control device of a hybrid vehicle that can reduce sense of incompatibility which is felt by a driver in switching a gear position.SOLUTION: In a speed control device that is applied to a hybrid vehicle 1 that includes: a gearbox 10 that includes an input shaft 11 to which an internal combustion engine 1 is connected through a clutch 24, an output shaft 12 connected in power transmissively with a driving wheel 5, and a plurality of speed change gear pairs G1 to G4 that is interposed between the input shaft 11 and an output shaft 12, and differ in transmission gear ratio mutually, and switches a gear position by selectively achieving rotation transmission between the input shaft 11 and the output shaft 12 by either a change gear pair among the plurality of the change gear pairs G1 to G4; and an MG3 connected by the output shaft 12, the MG3 is controlled so that ratio, to assist by the MG3 to requesting drive force being requested to the vehicle 1 during switching the gear position of the gearbox 10 when the gear position before switching is a high gear position, may become smaller than the case when the gear position before switching is a low gear position.SELECTED DRAWING: Figure 1

    【課題】変速段の切替時に運転者が覚える違和感を軽減することが可能なハイブリッド車両の変速制御装置を提供する。【解決手段】内燃機関1がクラッチ24を介して接続された入力軸11と、駆動輪5と動力伝達可能に接続された出力軸12と、入力軸11と出力軸12との間に介在し、かつ互いに変速比が相違する複数の変速ギア対G1〜G4とを含み、複数の変速ギア対G1〜G4のうちのいずれか一つの変速ギア対による入力軸11と出力軸12との間の回転伝達を選択的に成立させることにより変速段を切り替える変速機10と、出力軸12に接続されたMG3とを備えたハイブリッド車両1に適用される変速制御装置において、変速機10の変速段の切替中に車両1に対して要求されている要求駆動力に対してMG3でアシストする割合が、切替前の変速段が高速段の場合には切替前の変速段が低速段の場合よりも小さくなるようにMG3が制御される。【選択図】図1
