PROBLEM TO BE SOLVED: To suppress torque shock from occurring in a vehicle 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 that gradually increases pressure of operation oil so as to gradually increase transmission torque of a clutch 34 when transferring a mode from the EV mode to the HV mode; a torque gradually decreasing portion that gradually decreases driving torque of a motor 40 when transferring the mode from the EV mode to the HV mode; a transmission estimating portion that estimates transmission starting timing at which the transmission torque is generated when engaging the clutch; and a timing control portion that controls at least either one of timing for starting to gradually increase oil pressure and timing for starting to gradually decrease the driving torque, on the basis of the estimated transmission starting timing, 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、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、EVモードからHVモードへの移行時に、クラッチ34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と、EVモードからHVモードへの移行時に、モータ40の駆動トルクを漸減させるトルク漸減部と、クラッチを接続する際に伝達トルクが発生する伝達開始タイミングを推定する伝達推定部と、EVモードからHVモードへの移行時に、推定された伝達開始タイミングに基づいて、油圧の漸増開始タイミング及び駆動トルクの漸減開始タイミングの少なくとも一方を制御するタイミング制御部と、を備える。【選択図】図1
