摘要： PROBLEM TO BE SOLVED: To provide a vehicular control unit capable of attaining both fuel economy and drivability when a transition is made from a motor running mode to an engine running mode in a vehicle having an engine and electric motor.SOLUTION: For starting an engine 12 in a motor running mode and making a transition to an engine running mode, an electronic control unit starts the engine 12 by slipping an engine decoupling clutch K0 and igniting the engine 12 with a lockup clutch LU slipped. In this case, as an ignition beginning required time from a slip beginning time of the engine decoupling clutch K0 to an ignition beginning time of the engine 12 gets longer, the magnitude of the slip of the lockup clutch LU is diminished. Therefore, the magnitude of the slip is set to an appropriate value dependent on the controllability of an engine torque Te at the time of starting the engine. Thus, both avoidance of an engagement shock of the lockup clutch LU and suppression of degradation in fuel economy can be attained.

摘要： PROBLEM TO BE SOLVED: To provide a vehicular control unit capable of suppressing degradation in drivability occurring when an engine is started during motor rolling of a vehicle including the engine and an electric motor.SOLUTION: When an engine is started during motor rolling, an electronic control unit raises an engine rotating speed through slip engagement of an engine disconnection clutch K0. After the engine can autonomously rotate, the electronic control unit implements engine start control under which after engagement force of the engine disconnection clutch K0 is tentatively lowered, the engine disconnection clutch K0 is fully engaged. As an electric motor rotating speed is higher, an intake valve opening/closing timing is advanced earlier. Accordingly, as the electric motor rotating speed is higher, an engine torque is increased. This overcomes such a drawback that a time required until the engine rotating speed is synchronized with the electric motor rotating speed gets longer because of the high electric motor rotating speed. Eventually, degradation in drivability can be suppressed.
