PROBLEM TO BE SOLVED: To provide a hybrid vehicle controller which suppresses shock during starting up of an engine and improves fuel economy.SOLUTION: When starting up of an engine in a state that an electric motor MG is rotated, a clutch K0 is engaged and released by changing engagement pressure of the clutch K0 to one or more-pulse state. Therefore until starting up of the engine is completed, control for rubbing engine rotation speed Nusing compensation torque of the electric motor MG is not necessarily required. Namely, shock during starting up of the engine is suppressed and at the same time, fuel economy is improved.
