摘要： A hybrid vehicle control apparatus is provided, wherein an unpleasant sensation is not imparted to a driver depressing an accelerator pedal at the time of departure. In a hybrid vehicle control apparatus with an engine and a motor as the drive sources, and a battery for storing electrical energy from the engine or the kinetic energy of the vehicle converted by the motor, the vehicle is provided with an automatic transmission. Moreover, there is provided a discharge suppression mode which suppresses discharge from the remaining battery charge detected by a battery ECU, and a charge/discharge permit mode which permits charge/discharge of the battery. At a time of vehicle departure, departure assistance is performed only when a degree of throttle opening showing an acceleration intention of the driver exceeds a determination threshold which is larger than a determination threshold for at the time of the discharge/charge permit mode.

摘要： In order to prevent an occurrence of dieseling phenomenon, and to prevent engine rotation speed from decreasing during idle operation or the idle operation from being stopped, in step S111, it is determined whether the flag value of an idle stop flag F_IDLSTP is “1” or not. If it is determined that the determination result is “YES”, that is, if it is determined that the internal combustion engine body is stopped, 0% is set to a target purge control valve drive duty value PGCMD (step S105), and 0 is set to the target purge flow rate QPGC (step S106). If it is determined that the determination result is “NO”, that is, when the internal combustion engine body is in operation, PGCMD calculation processing is executed (step S112). While the internal combustion engine body is stopped, execution of purge is stopped, thereby an occurrence of a dieseling phenomenon which is caused because the flow rate of the air flowing into the internal combustion engine body increases and the air is compressed, is prevented, thereby suppressing vibration from occurring in the internal combustion engine body.

摘要： A hybrid vehicle control apparatus for improving fuel consumption ratio by making appropriate the deceleration perception of the hybrid vehicle is provided. It is determined whether the flag setting of a brake ON determination flag is “1”. If the brake is OFF, a brake OFF regeneration amount is obtained, and is assigned to the deceleration regeneration computed value. It is determined whether a remaining batter charge is greater than or equal to a predetermined normal power generation mode execution upper limit remaining charge. In the case where the determination result is yes, it is determined whether a control vehicle speed is greater than or equal to a predetermined high speed deceleration regeneration reduction lower limit vehicle speed. In the case where the determination result is yes, the value obtained by multiplying the deceleration regeneration computed value by a predetermined high speed deceleration regeneration reduction coefficient, for example 0.8, is set as a new deceleration regeneration computed value.

摘要： A control system for an internal combustion engine having an intake system and an exhaust system is disclosed. The exhaust system includes a catalyst, and the intake system includes a throttle valve. The engine is mounted on a vehicle having a brake booster to which an intake pressure at downstream of the throttle valve is introduced. The catalyst temperature rise control in which the intake air amount is increased after starting of the engine and the ignition timing is retarded according to a rotational speed of the engine is performed. When a pressure difference between the detected intake pressure and the atmospheric pressure during the catalyst temperature raising control is less than a predetermined pressure, the increased intake air amount and the retard amount of the ignition timing is gradually decreased.

摘要： A hybrid vehicle comprises an engine and a motor as its drive sources. The hybrid vehicle also comprises a control device which stops the fuel supply to the engine at the time of vehicle deceleration, and performs regenerative braking by the motor depending on the deceleration state, in which the engine is a cylinder deactivation engine capable of switching between all cylinder operation for operating all cylinders and cylinder deactivation operation for deactivating at least one or more cylinders. The cylinder deactivation operation is conducted during deceleration state of the vehicle to reduce pumping losses of the engine so that the regeneration efficiency of the motor is improved. The control device comprises an abnormality detection device which detects abnormality in the cylinder deactivation engine, and a motor output limiting device which limits the output of the motor in response to the detection of the abnormality.
