Abstract: When an EV cancellation switch is turned on while a control mode is a CD mode and a traveling mode is an EV traveling mode, when a catalyst temperature is lower than a threshold and when a vehicle speed is lower than a threshold, a controller executes control processing including a step of executing first VVT control, a step of, when the catalyst temperature is higher than or equal to the threshold or when the vehicle speed is higher than or equal to the threshold, executing second VVT control and a step of switching the control mode into a CS mode.

Abstract: In a vehicle capable of external discharging to supply electric power generated from motive power of a vehicle-mounted engine to a receiver external to the vehicle (hereinafter “engine-operated discharging”), an ECU determines, during engine operation, whether engine-operated discharging is being done. When engine-operated discharging is not being done, the ECU sets a first malfunction determination condition (condition that postulated misfire malfunction was detected in two trips) as an engine malfunction determination condition and, when the first malfunction determination condition is met, lights a check engine light. When engine-operated discharging is being done, the ECU sets a second malfunction determination condition (condition that postulated misfire malfunction was detected in one trip) as the engine malfunction determination condition and, when the second malfunction determination condition is met, lights the check engine light and automatically stops the engine.

Abstract: In a vehicle that includes an electrically heatable first catalyst EHC (140) in an exhaust passageway of an engine and a second catalyst UFC (145) disposed downstream of the EHC, an ECU (150) predicts that the load following starting of the engine will be higher than the load that corresponds to the exhaust gas purification capability of the EHC, and starts an engine motoring control of forcing the engine to turn via an electric motor (S32), if, during a pre-heating control of electrically controlling the EHC prior to starting of the engine, the demanded drive force F is greater than a predetermined value F1 and the amount of increase ?F of the demanded drive force F per unit time is greater than a predetermined amount ?F1.

Abstract: An abnormality determination apparatus for an electrically heated catalyst provided in a plug-in hybrid vehicle having a battery that is charged by connecting an external charging device to an external electric power supply is equipped with an abnormality determination portion that makes a determination on an abnormality in the electrically heated catalyst when the external charging device is connected to the external electric power supply.

Abstract: An exhaust gas purification apparatus which is installed in a flow channel of an exhaust gas discharged from an engine, includes: a first purification device that purifies one component contained in the gas; a heating device that heats the purification device to a predetermined temperature in a period from before the engine is started to a first point in time that is after the engine is started; control device that controls an air-fuel ratio of the gas so as to obtain a air-fuel ratio suitable for purifying the one component in a period from the time when the engine is started to a point in time that is on or after a time at which the purification device is heated to the predetermined temperature; and an adsorption device that communicates with the downstream of the first purification device and adsorbs another component contained in the gas.
