摘要： A diagnostic apparatus of a hybrid vehicle has an internal combustion engine, a motor that generates a driving force for vehicle travel, and a diagnostic unit that diagnoses a vehicle state by motoring the internal combustion engine using the motor in a state where an output of the internal combustion engine is zero. The apparatus includes a required driving force detection unit that detects a required driving force of a driver; a determination unit that determines whether or not a remaining time required until a diagnostic completion is a predetermined time or less, in a case where the required driving force with a predetermined lower limit value or more is detected by the required driving force detection unit when the vehicle state is diagnosed by the diagnostic unit; and a control device that causes the motor to output the driving force for the vehicle travel, in a case where the remaining time is the predetermined time or less in the determination result of the determination unit, and continues the vehicle state diagnosis using the diagnostic unit by motoring the internal combustion engine using the motor in the state where the output of the internal combustion engine is zero.

摘要： A misfire detecting apparatus for an internal combustion engine is provided. The engine has an output shaft connected via a torsion element to an input shaft of a transmission mechanism. A transmission rotational speed parameter indicative of a rotational speed of the input shaft is detected. A modified engine rotational speed parameter is calculated by modifying the detected engine rotational speed parameter based on the transmission rotational speed parameter, an engine rotation moment on the input side of the torsion element, and a transmission rotation moment on the output side of the torsion element. An average change amount of the modified rotational speed parameter, and an inertia speed changing component, are calculated. Further, a corrected rotational speed parameter is calculated by correcting the modified rotational speed parameter according to the average change amount and the inertia speed changing component. A relative speed parameter is calculated based on the corrected rotational speed parameter, and a determination parameter is calculated by integrating the relative speed parameter. The misfire determination is performed based on the determination parameter.

摘要： A control apparatus for a hybrid vehicle of the present invention determines whether a brake switch flag F_BKSW is “1” or not (step S101), and in the case where the brake is on (“yes”), obtains a deceleration regeneration computation value DECRGN by table retrieval from a #REGENBR table. In the case where the brake is off (“no”), it is determined whether a fuel supply cut delay time regeneration flag F_RGNFCD is “1” or not (step S104). In the case where regeneration is not performed in the fuel supply cut delay time (“no”), a deceleration regeneration computation value DECRGN is obtained by table retrieval from a #REGEN table (step S105). On the other hand, in the case where regeneration is performed in the fuel supply cut delay time (“yes”), a deceleration regeneration computation value DECRGN is obtained by table retrieval from a #RGNNFCD table (step S106).

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： An engine control apparatus is provided for a hybrid vehicle that installs an engine and a motor as driving power sources for driving wheels as well as an automatic transmission such as CVT. The engine control apparatus basically operates to enable automatic stop and restart of the engine in response to drive conditions of the vehicle. In addition, the engine control apparatus cuts off fuel supply to the engine at a deceleration mode of the vehicle. At a deceleration mode of the vehicle under execution of fuel cut, the engine control apparatus maintains idle rotation of the engine by operating the motor to rotate in response to engine speed until the automatic transmission is returned to a restart-enable reduction ratio (e.g., 2.2 to 2.45). That is, the engine control apparatus allows execution of an engine stop after securing a restart-enable state of the automatic transmission. Incidentally, the motor produces motor torque, which is increased in response to decrease of the engine speed in a range between 700 and 1000 rpm, then, which is maintained at a prescribed value (e.g., 8.5 kgf-m), for example.
