摘要:
A control device for a hybrid vehicle includes an actual intake gas negative pressure detection unit which detects an intake air negative pressure for the engine, an estimated intake gas negative pressure calculation unit which estimates an intake air negative pressure based on a revolution number of the engine and an opening degree of a throttle, and an engine control unit which compares an actual intake gas negative pressure obtained by the actual intake gas negative pressure detection unit with an estimated intake gas negative pressure obtained by the estimated intake gas negative pressure calculation unit. The engine control unit prohibits a fuel supply to the engine until the actual intake gas negative pressure matches the estimated intake gas negative pressure, and carries out the fuel supply to the engine when the actual intake gas negative pressure matches the estimated intake gas negative pressure.

The control system of the present invention is provided for a hybrid vehicle with an engine and a motor, which are power sources, and a power storage unit for storing energy generated by the output from the engine and regenerative energy produced by regeneration of the motor when the vehicle decelerates. Based on monitoring the state of charge of the power storage unit, when the stored energy is discharged so that the remaining charge is decreased from an initial state of charge, which was detected when the vehicle started running, by a predetermined amount, the function of the motor is switched from the discharging of the power storage unit to the charging of the power storage unit.

The engine control system for a hybrid vehicle, according to the present invention, having an internal combustion engine and an electric motor as driving force sources, comprises: a clutch, provided between the engine and a transmission system, for disabling and enabling driving force transmission between the engine and the transmission system; clutch disengagement detector (S114;S126) for detecting engagement/disengagement of the clutch; engine speed detector for detecting an engine speed; and fuel cutter for permitting stopping and restarting of the engine in accordance with at least a result of detection by the clutch disengagement detector among predetermined drive conditions, and cutting fuel supply to the engine when the vehicle decelerates, a fuel-supply restart engine speed at which fuel supply is resumed being set in the fuel cutter. Stopping the engine is accomplished by cutting fuel supply by the fuel cutter, and once the engine stop is initiated, even when the engine speed reaches the fuel-supply restart engine speed, fuel supply cut by the fuel cutter is maintained, and when the engine speed detected by the engine speed detector at a time of disengagement of the clutch is detected by the clutch disengagement detector is equal to or lower than a predetermined engine speed (S116), fuel supply cut by the fuel cutter is maintained whereas when the detected engine speed is higher than the predetermined engine speed, fuel supply is restarted.

A hybrid vehicle control apparatus is provided which can improve fuel consumption. There is provided: a cylinder cut-off determination section (F_ALCSSTB) for determining whether all cylinders should be cut off; a cylinder cut-off cancellation determination section (F_ALCSSTP) for determining whether cylinder cut-off cancellation conditions have been satisfied; a cylinder cut-off execution section (F_ALCSSOL) for operating a spool valve (SV) when the cylinder cut-off determination section determines that cylinder cut-off is possible; and a cylinder cut-off control section (F_ALCS) for cutting off the cylinders of the engine based on the operating conditions of the cylinder cut-off determination section, the cylinder cut-off cancellation determination section and the cylinder cut-off execution section. When the voltage of an auxiliary battery (4), being the drive source of the spool valve, is at or greater than a predetermined voltage, and the oil temperature (TOIL) is within a predetermined range, the cylinder cut-off determination section determines that cylinder cut-off is possible.
