Abstract: A control apparatus for a hybrid vehicle in which a friction clutch and a one-way clutch are disposed in parallel with each other between an engine and an electric motor. The transmission is disposed between the electric motor and drive wheels. The friction clutch connects and disconnects between the engine and the electric motor. The one-way clutch transmits a drive force in a direction from the engine toward the electric motor. The vehicle runs in (i) an electric-motor running mode with operation of the electric motor or (ii) a hybrid running mode with operation of the engine. The control apparatus is configured, upon execution of a shift-up action of the transmission with the hybrid running mode being selected and with the friction clutch being in a non-engaged state, to execute a shift-up action control by which the shift-up action starts to be executed after the friction clutch has been engaged.
