PROBLEM TO BE SOLVED: To provide a shift control method for a hybrid vehicle by which drivability and acceleration performance can be increased compared with a conventional one.SOLUTION: The shift control method for a hybrid vehicle is provided in which: torque of an engine 1 and a motor generator 2 is limited and a clutch 3 is disengaged upon automatic shifting of a parallel-type hybrid vehicle, then gear changing is carried out by reducing the number of revolutions of the motor generator 2 to the target number of revolutions corresponding to rotation of driving wheels 9; the number of revolutions of the motor generator 2 is increased simultaneously with the gear changing thereby generating a torque; and the torque of the engine 1 is recovered by engaging the clutch 3 when the reduced speed of the engine 1 and the reduced number of revolutions of the motor generator 2 are coincident with each other.

    【課題】ドライバビリティと加速性能を従来よりも向上し得るハイブリッド自動車の変速制御方法を提供する。【解決手段】パラレル型のハイブリッド自動車における自動変速時にエンジン1及びモータジェネレータ2のトルクを制限してクラッチ3を切断した後、モータジェネレータ2の回転数を駆動輪9の回転に合う目標回転数まで落としてギヤチェンジを実施し、該ギヤチェンジと同時にモータジェネレータ2の回転数を上げてトルクを発生し、低下してきたエンジン1の回転数と前記モータジェネレータ2の回転数とが一致したところで前記クラッチ3を接続して前記エンジン1のトルクを復帰させる。【選択図】図1
