摘要： A hybrid vehicle includes an internal combustion engine, an electrical storage device, a rotary electric machine, and a controller. The hybrid vehicle travels in a selected one of a charge sustaining mode and a charge depleting mode. Switching from the charge depleting mode to the charge sustaining mode is controlled such that a first state of charge is higher than a second state of charge. In the first state of charge, the controller switches from the charge depleting mode to the charge sustaining mode at the time when operation characteristic of the intake valve is unchangeable to a desired operation characteristic. In the second state of charge there is switching from the charge depleting mode to the charge sustaining mode at the time when the operation characteristic of the intake valve is changeable to a desired operation characteristic.

摘要： A hybrid vehicle includes an electric motor, an internal combustion engine, an exhaust emission control device and a controller. The controller is configured to execute catalyst warm-up control for warming up a catalyst of the exhaust emission control device. The catalyst warm-up control includes first control and second control. The first control is control for operating the internal combustion engine at a first operating point. The second control is control for, after the first control is executed, operating the internal combustion engine at a second operating point irrespective of a driving force that is required to propel the hybrid vehicle. An output of the internal combustion engine at the second operating point is larger than an output of the internal combustion engine at the first operating point. The controller is configured to operate the internal combustion engine while an ignition timing of the internal combustion engine at the time when the first control is executed is set to a retarded side with respect to an ignition timing of the internal combustion engine at the time when the second control is executed. The controller is configured to, when the first control is executed, control the variable valve actuating device such that the operation characteristic becomes the first characteristic. The controller is configured to, when the second control is executed, control the variable valve actuating device such that the operation characteristic is changed to the second characteristic. The controller is configured to, after the second control is executed, operate the internal combustion engine on the basis of the driving force that is required to propel the hybrid vehicle and control the variable valve actuating device on the basis of a rotation speed and torque of the internal combustion engine.

摘要： A control device for an engine provided in a vehicle includes a controller. The engine includes an intake valve and a variable valve mechanism. The variable valve mechanism changes an opening/closing timing while maintaining a valve opening period of the intake valve. The controller sets an advance amount of the closing timing of the intake valve at the time when the engine is started, such that a first closing timing is earlier than a second closing timing of the intake valve. The first closing timing is the closing timing when a trip in which an operating period of the internal combustion engine is equal to or less than a predetermined period continues a predetermined number of times. The second closing timing is the closing timing before the number of continuous trips reaches the predetermined number of times. The trip is a period from activation to stop of the vehicle.

摘要： The hybrid vehicle includes an internal combustion engine, a rotary electric machine, an electrical storage device and a controller. The controller is configured to execute output control. An opening degree of the throttle valve is controlled in the output control such that, when a temperature of the electrical storage device is lower than a predetermined temperature, the output of the internal combustion engine is reduced below a predetermined output. The controller is further configured to control the variable valve actuating device such that at least one of a valve lift or valve operating angle of the intake valve at the time when the output control is executed is larger than the corresponding at least one of the valve lift or valve operating angle of the intake valve at the time when the output control is not executed.

摘要： An engine has a variable valve actuation device for controlling an actuation characteristic of an intake valve that is an amount of lifting the intake valve and/or a working angle on the intake valve. When the intake valve, having the actuation characteristic (or lifted in an amount and/or worked by a working angle), as controlled by the variable valve actuation device, has the actuation characteristic fixed (YES in S120), a range applied to set therewithin an output that the engine is required to provide is limited to be narrower and a power storage device's controlled target SOC is raised to be higher (S150, S160, S170) than when said actuation characteristic is not fixed (NO in S120).

摘要： An engine has a variable valve actuation device for controlling an actuation characteristic of an intake valve that is an amount of lifting the intake valve and/or a working angle on the intake valve. When the intake valve having the actuation characteristic (or lifted in an amount and/or worked by a working angle) controlled by the variable valve actuation device has the actuation characteristic (or the amount and/or the angle) fixed, intermittently operating the engine is not unconditionally stopped, and when a power storage device is not limited in chargeability and dischargeability and a cranking torque is ensured to ensure that the engine is startable, intermittently stopping the engine is permitted.

摘要： The occurrence of the misfire having a level at which exhaust purifying function of a catalyst is impaired (OT-level misfire) is detected. Upon the detection of the OT-level misfire, basic OT risk from the misfire is multiplied by a correction coefficient corresponding to the accumulated PM amount on the catalyst. The basic OT risk from the misfire is a basic value of OT risk from the misfire which is set based on the operating condition of the engine. The correction coefficient is set to a smaller value as the accumulated PM amount increases. Therefore, the OT risk from the misfire after the multiplication decreases as the accumulated PM amount increases. When a predetermined judgement condition with the OT risk from the misfire is established, it is judged that the misfire having the level occurs.

摘要： A controller for an engine includes processing circuitry configured to perform fuel cut-off for regenerating the filter by burning fine particulate matter collected in the filter. The processing circuitry is configured to perform an interruption process for interrupting the fuel cut-off in a case in which warming of the passenger compartment is requested when the fuel cut-off is being performed and an engine coolant temperature, which is a temperature of the engine coolant, becomes lower than or equal to a predetermined temperature after the fuel cut-off is started.
