摘要： If an amount of fuel is not increased and a direct injection air-fuel ratio learning has not been completed, fuel injection from a port fuel injection valve is stopped without executing EGR, fuel injection control is executed such that the fuel injection occurs only from an in-cylinder fuel injection valve, and the direct injection air-fuel ratio learning is executed. If the amount of the fuel is increased, the fuel injection from the port fuel injection valve is stopped without executing EGR and air-fuel ratio feedback control, and an engine and an EGR valve are controlled such that fuel injection occurs only from the in-cylinder fuel injection valve.

摘要： A hybrid vehicle having a controller controls output torque of an engine and output torque of a generator motor so as to apply requested torque to a drive shaft. The controller performs engine intermittent operation to stop operation of the engine when a given engine operation stop condition is satisfied, and start the engine when a given engine start condition is satisfied. The controller makes an in-cylinder injection valve abnormality determination while causing a total amount of fuel to be injected from an in-cylinder injection valve, and makes a port injection valve abnormality determination while causing the total amount of fuel to be injected from a port injection valve. If at least one of abnormality determinations concerning the in-cylinder injection valve and the port injection valve has not been made, the engine is operated so that the load of the engine falls within a predetermined range.

摘要： A vehicle includes an engine, a first MG (motor generator), a second MG, a motive power split device, and an ECU. ECU temporarily determines whether or not an imbalance abnormality has occurred based on an air-fuel ratio, and when it is temporarily determined that the imbalance abnormality is present, controls the engine such that the engine is in an idle state and formally determines whether or not the imbalance abnormality has occurred based on fluctuations in engine rotation speed. During a stop at idle, ECU determines whether or not the formal determination process of the imbalance determination is ongoing and carries out pressing control to cause the first MG to generate pressing torque Tp when the formal determination process is not ongoing and does not carry out the pressing control so as not to cause the first MG to generate pressing torque Tp when the formal determination process is ongoing.

摘要： A hybrid vehicle 20 sets a tentative limit value Win0 of determining a fuel increase relation with respect to a selected gearshift position SP for driving (S220, S230, S350), and performs increasing correction of a fuel injection amount according to either a first OT increase factor setting map or a second OT increase factor setting map that is enabled based on a relation of an input limit Win of the battery 50 to the tentative limit value Win0. Prohibition of fuel cutoff may be cancelled, based on a relation of the input limit Win to a driving force demand in an accelerator-off state set at the selected gearshift position SP. Even in this case, the increasing correction enables temperature regulation of an exhaust gas purification catalyst, with a view to controlling deterioration of the exhaust gas purification catalyst in an actual fuel cutoff condition after cancellation of the prohibition of the fuel cutoff. The deterioration of the exhaust gas purification catalyst is thus favorably controlled, irrespective of the selected gearshift position SP.

摘要： In response to the driver's depression of a brake pedal in requirement of catalyst deterioration control with a catalyst deterioration control flag Fc set equal to 1, the braking control of the invention controls the operation of a motor to make a rotation speed Ne of an engine approach to a target rotation speed Ne* in a state of continued combustion (firing) of the engine (steps S180 and S190). Such control ensures a quick decrease of the rotation speed Ne of the engine to the target rotation speed Ne*, thus effectively reducing the wasteful fuel consumption due to the continued operation of the engine at a high rotation speed and enhancing the overall energy efficiency of the vehicle.

摘要： In a hybrid vehicle of the invention, the control procedure corrects an idling intake air flow Qidl to enable an engine immediately after its start to generate an output power Pe that is substantially equivalent to an engine power demand Pe*. After the correction, the control procedure controls the engine to have an intake air flow Qe with reflection of an intake air flow correction value Qec and controls a motor MG1 to generate electric power by using the output power Pe of the engine and to charge a battery with the generated electric power within an input limit Win of the battery. The control of the invention ensures that the output power Pe of the engine does not exceed the engine power demand Pe* in restriction of the charge level of the battery. This arrangement effectively prevents the state of charge SOC of the battery, which is charged with the electric power generated by the motor MG1, from exceeding the input limit Win.

摘要： In a hybrid vehicle, when the shift position SP is set to the S position at which a driver is allowed to select any one of the shift positions SP1 to SP6, and it is determined that warm-up of a purifying device has not been completed, the target air-fuel ratio AF* is set based on the S position/low coolant temperature-time target air-fuel ratio setting map. The air-fuel ratio AF* set based on the S position/low coolant temperature-time target air-fuel ratio setting map tends to be richer than the target air-fuel ratio AF* set based on any one of the normal-time target air-fuel ratio setting map and the D position/low coolant temperature-time target air-fuel ratio setting map that are used when the D position is selected.
