When an acceleration request is issued, an electronic control unit for a hybrid vehicle performs control for producing an acceleration feeling of setting a target engine rotation speed to an initial rotation speed (=basic initial value+initial value correction value) which is lower than an optimal-fuel-efficiency rotation speed at which required engine power is able to be most efficiently output and increasing the engine rotation speed from the initial rotation speed to the optimal-fuel-efficiency rotation speed at a rotation speed increase rate (=basic increase rate+increase rate correction value) based on the elapse of time. When the target supercharging pressure is high, the initial value correction value is set to a greater value and the increase rate correction value is set to a greater value than when the target supercharging pressure is low.
