PROBLEM TO BE SOLVED: To suppress torque shock from occurring in a vehicle, even if transmission torque of a clutch overshoots a command value, when transferring a mode from an EV mode to an HV mode.SOLUTION: A driving control device (70), which controls driving of a hybrid vehicle (10) which executes an EV mode and an HV mode, comprises: an oil pressure gradually increasing portion 70 that gradually increases pressure of operation oil so as to gradually increase transmission torque of a clutch; a rotation speed difference determining portion 70 that determines whether a rotation speed difference resulting from subtracting rotation speed of an output shaft 34b from rotation speed of an input shaft 34a of the clutch is larger than prescribed rotation speed differences; an engine rotation speed determining portion 70 that determines whether rotation speed of an engine is higher than prescribed rotation speed; and an oil pressure control portion 70 that makes the oil pressure gradually increasing portion to start to gradually increase oil pressure, under the condition that it is determined that the rotation speed difference is larger than the prescribed rotation speed difference and it is determined that the rotation speed of the engine is higher than the prescribed rotation speed, when transferring the mode from the EV mode to the HV mode.SELECTED DRAWING: Figure 1

    【課題】EVモードからHVモードへの移行時に、クラッチの伝達トルクが指令値をオーバーシュートしたとしても、車両にトルクショックが生じることを抑制する。【解決手段】EVモードとHVモードとを実行するハイブリッド車両10の駆動を制御する駆動制御装置70であって、クラッチの伝達トルクを漸増させるように作動油の油圧を漸増させる油圧漸増部70と、クラッチの入力軸34aの回転速度から出力軸34bの回転速度を引いた回転速度差が所定回転速度差よりも大きいことを判定する回転速度差判定部70と、エンジンの回転速度が所定回転速度よりも高いことを判定するエンジン回転速度判定部70と、EVモードからHVモードへの移行時に、上記回転速度差が所定回転速度差よりも大きいと判定され、且つエンジンの回転速度が所定回転速度よりも高いと判定されたことを条件として、油圧の漸増を開始させる油圧制御部70と、を備える。【選択図】図1
