摘要： A method for guaranteeing starting performance of an engine for maintaining driving performance is provided. The method includes executing a quasi-failure mode in which the engine is changed to a driving state when an engine cranking apparatus state is maintained equal to or less than a threshold for a predetermined period of time. As a result, the engine is driven in the quasi-failure mode while the hybrid vehicle is driven in the EV mode to prevent the vehicle system from being aggravated and fundamentally preventing the degradation in the stability of the vehicle causing driver discomfort.

摘要： The present invention has an object to provide a catalyst temperature control device that can properly control a temperature of a catalyst which influences an emission performance of an internal combustion engine.A plurality of temperature measurement points are disposed continuously or dispersedly at least in a flow path direction inside the catalyst. The temperature measurement points can include not only actual measurement points where temperature sensors are disposed, but also virtual measurement points where temperature sensors are not disposed. A control point is selected from the plurality of temperature measurement points in accordance with operation conditions of the internal combustion engine, and a target value of the temperature of the catalyst is set. As a temperature at the selected control point, when the control point is the actual measurement point, an actual measurement value by the temperature sensor can be used. When the control point is the virtual measurement point, the temperature at the control point can be estimated by interpolation calculation using a temperature or temperatures at one or a plurality of actual measurement points near the control point. A manipulated variable of the internal combustion engine is determined based on a difference between the temperature at the control point acquired by actual measurement or estimation and the target value, and the internal combustion engine is operated in accordance with the determined manipulated variable.

摘要： Methods and systems for controlling an engine are provided. In some examples, the engine has at least a cylinder and a compression device coupled to an intake of the engine, and the method includes, during engine re-start operation of an engine idle-stop condition, commencing combustion in the cylinder from a non-combusting condition, the combustion in a two-stroke combustion cycle of the cylinder.

摘要： An engine controller is applied to a system that includes an engine and an exhaust purifying catalyst for purifying exhaust gas of the engine. The engine controller has an idle stopping means, a catalyst temperature detecting means and an engine restarting means. The idle stopping means stops the engine when a predetermined idle stop condition is satisfied. The catalyst temperature detecting means detects a temperature of the exhaust purifying catalyst while the engine is stopped by the idle stopping means. The engine restarting means restarts the engine when the temperature of the exhaust purifying catalyst, which is detected by the catalyst temperature detecting means, becomes equal to or lower than an engine restart determination temperature, which is determined on a basis of an activation temperature of the exhaust purifying catalyst.

摘要： Method for maintaining a catalyst of an emissions system in a hybrid electric vehicle in an operative condition is disclosed. The method includes sensing that an engine of a hybrid electric vehicle has stopped operating. A time period is predicted after which a catalyst of an emissions system associated with the engine will cool to a light-off temperature below which the catalyst becomes ineffective. The predicting step is based on known qualities of the catalyst and ambient conditions in which the vehicle is being operated. The engine is restarted when the predicted time period has expired thereby maintaining the catalyst at temperatures in excess of the light-off temperature.

摘要： Methods and systems are provided for extending an engine-off period of a hybrid vehicle while reducing engine cold-start emissions. During an engine pull-up to meet operator demand, the engine is held at a higher power for a longer duration to aggressively heat the exhaust catalyst. Subsequently, the engine is pulled up to a lower power and held at the lower power for shorter bursts of time to activate the exhaust catalyst.
