摘要： A control system and control method for a hybrid vehicle, which properly determine based on a predicted charge amount whether or not to change a speed position, to thereby obtain a larger charge amount, thereby making it possible enhance fuel economy of the hybrid vehicle. A first charge amount is estimated which is an amount of electric power charged into a storage battery when regeneration is performed by an electric motor in a state in which the speed position of a stepped transmission is held, for a predetermined regeneration time period. Further, a second charge amount is estimated which is an amount of electric power charged into the storage battery when the speed position is changed to a target speed position within the regeneration time period, and regeneration by the electric motor 4 is performed until the regeneration time period elapses.

摘要： When an engine load QC is equal to or larger than a predetermined value, an acceleration-state determiner determines that a turbine is in an acceleration state, and a supercharging-pressure-control-state determiner determines that supercharging-pressure controller (a bypass valve, a wastegate, and a variable flap) of a turbocharger are in a maximum supercharging pressure control state (a closed valve state), i.e., when a delay coefficient α of the turbocharger calculated by a delay-coefficient calculator on the basis of an actual supercharging pressure πc and a convergent value πc* of a supercharging pressure calculated by a convergent-value calculator indicates a value peculiar to the turbocharger, a failure of the supercharging-voltage controller is determined on the basis of the delay coefficient α. Thus, it is possible to secure a high failure detection accuracy, and increase a frequency of performing failure detection even when the engine load QC suddenly changes to cause a delay in a response of the supercharging pressure πc.
