摘要： A controller of a hybrid vehicle is configured to operate the internal combustion engine with ignition timing of the internal combustion engine during the execution of the first warm-up control for operating the internal combustion engine at a first operating point further on a retard side than ignition timing of the internal combustion engine during the execution of the second warm-up control for operating the internal combustion engine at a second operating point, regardless of the driving force required for traveling after the execution of the first warm up control. The controller is configured to set the output of the internal combustion engine and the operation characteristic of the intake valve in accordance with a predetermined characteristic relationship in which the output of the internal combustion engine and the operation characteristic of the intake valve correspond to each other during the execution of the second warm-up control.

摘要： Methods and systems are provided for using compression heating to heat a cylinder piston before cylinder combustion is resumed. Cylinder heating is achieved using combinations of slow unfueled engine rotation where the engine cylinders are heated via compression stroke heating, and slow compressor rotation where the cylinders are heated via compression heating. One or more intake or exhaust heaters may be concurrently operated to expedite cylinder heating.

摘要： Methods and systems are provided for controlling a vehicle engine to adjust exhaust warm-up strategy based on a vehicle network information. In one example, in response to an expected decrease in temperature of a catalyst of a vehicle below a threshold and an estimated duration thereof based on communications external from the vehicle, a method may include delaying catalyst heating actions, when the catalyst heating actions are determined to be unable to heat up the catalyst to threshold temperatures. However, the catalyst heating actions may be enabled when the catalyst heating actions are determined to be able to achieve the threshold temperature within the duration.

摘要： A hybrid vehicle includes an input device that is used by a user to request an increase in the amount of charge of the power storage device. When a request for increasing the amount of charge is made using the input device, a control device controls charging of a power storage device by a generating device so that charging of the power storage device is promoted, warms a catalyst device by operating an internal combustion engine while limiting the output of the internal combustion engine, and when the warming of the catalyst device and the request for increasing the amount of charge that is made using the input device overlap each other, the control device eases the output limitation of the internal combustion engine.

摘要： In a vehicle including an engine, an electrically heatable catalyst device (EHC), and a first motor generator that generates electric power in accordance with the engine's motive power with the vehicle in a substantially stopped state with a vehicular speed lower than a threshold vehicular speed, an ECU determines, based on an amount A by which an accelerator pedal is operated and a vehicular speed V, whether a large accelerator operation has been performed with the vehicle in the substantially stopped state. If the ECU determines that the large accelerator operation has been performed with the vehicle in the substantially stopped state, the ECU activates an energization timer, and before the energization timer reaches a reference energization period of time α, the ECU energizes the EHC, and once the energization timer has reached the reference energization period of time α, the ECU ceases energizing the EHC.

摘要： A hybrid vehicle in which at least two shift ranges can be selected for a single running direction includes an engine, a motor generator, an EHC raising the temperature of a catalyst for cleaning up an exhaust gas from the engine, and an ECU. While the vehicle is running, if the engine is stopped and, of the two shift ranges, a shift range where larger decelerating force is produced by regenerative braking of the motor generator has been selected, the ECU causes the EHC to raise the temperature of the catalyst using electric power generated by the motor generator.

摘要： An apparatus for controlling an internal combustion engine executes air-fuel ratio feedback control based on a detection result of an exhaust gas sensor and when the engine is shut down, stops energization of a heater of the exhaust gas sensor at a predetermined timing after shutdown of the engine, heater control of the exhaust gas sensor is executed, which is suitable for a case in which shutdown time of the engine is set long, and thus the exhaust gas sensor is protected from thermal shock. The control apparatus sets timing for stopping energization of a heater of an exhaust gas sensor after shutdown of the engine, to a point in time when a predetermined time set based on outside air temperature has elapsed, or a point in time when cooling water temperature of the engine has dropped to a predetermined temperature.

摘要： An engine controller includes: a warm-up control unit that performs warm-up operation for letting the engine continuously operate until an integration value of air intake of the engine comes to a predetermined integration value in order to warm up a catalyst provided in an exhaust system when the engine is first started after start-up of the vehicle; and a continuation control unit that lets the engine continuously operate for a predetermined period subsequent to an end of the warm-up operation. The continuation control unit takes an output value of the engine as a request output value when the request output value of the engine is a predetermined idling output value or more that is smaller than the predetermined warm-up output value and takes the output value as the warm-up output value when the request output value is less than the predetermined idling output value.
