摘要： A method and system for controlling an internal combustion engine upon initial entry into a speed control mode and upon transitions between dynamic operating modes of a speed control system includes means for determining an actual vehicle acceleration and means for determining an actual wheel torque. A controller determines an initial desired wheel torque based on the actual vehicle acceleration and the actual wheel torque and controls the torque generated by the engine based on the initial desired wheel torque so as to smoothly control the speed of the vehicle.

摘要： In an engine mounted on a hybrid vehicle, even in an atmosphere that readily cools down a catalyst by relatively low-temperature gaseous exhausts, for example, under a fuel cut control, the structure of the invention quickly warms up the catalyst and maintains a conversion efficiency of the gaseous exhausts at a high level. When it is determined that an engine is in operation and the fuel cut control is being performed, a reflux valve is turned on to reflux the gaseous exhausts into an intake conduit. This control procedure enables the relatively low-temperature gaseous exhausts to be refluxed to the intake conduit, instead of flowing into the catalyst, thereby preventing the catalyst from being cooled down.

摘要： A traction control system for an automotive vehicle performs traction control by controlling an engine having an exhaust system with a catalytic converter and a brake system to reduce driving force delivered to driving wheels, so as to diminish excessive slippage of the driving wheels. The traction control system includes a controller for changing an engine control mode from an ordinary control mode to an exhaust temperature reduction mode when a temperature of the catalytic converter is higher than a predetermined temperature and changing a control parameter of engine control, so that the engine provides an increase in output torque in the exhaust temperature reduction mode.

摘要： The hybrid vehicle includes an engine coupled to a drive shaft, a first motor that rotates the engine a second motor coupled to the drive shaft, a transmission interposed between the engine and the first motor, and the second motor, and a control device configured to execute a decrease process and an increase process. The decrease process is a process for decreasing deceleration of the hybrid vehicle by restricting fuel cut in the engine. The increase process is a process for increasing a rotational speed of the engine to a target rotational speed by power running torque of the first motor during deceleration by downshift of the transmission. The target rotational speed in the increase process is set to a lower value during execution of the decrease process than during stop of the decrease process.

摘要： Systems and methods are described for emissions control of a hybrid vehicle. An instruction to switch from a combustion engine power mode of the hybrid vehicle to an electric power mode of the hybrid vehicle is received. A temperature of a catalyst associated with a combustion engine of the hybrid vehicle is identified, where exhaust gases from the combustion engine are passed over the catalyst. If the temperature of the catalyst is at, or above, a threshold level, the hybrid vehicle is switched to the electric power mode, and the combustion engine is switched off. If the temperature of the catalyst is below the threshold level, the hybrid vehicle is switched to the electric power mode, and the catalyst temperature is maintained at, or above, the threshold level.

摘要： A system and method for power management of hybrid electric vehicles is provided. In some implementations, a plug-in series hybrid electric vehicle may include an engine, a motor/generator (MG), a traction motor, an energy storage device, and a controller. The controller is coupled to the engine and the MG to control operation of the engine and the MG such that a state-of-charge (SOC) of the energy storage device tracks a dynamic reference SOC profile during a trip and an average engine power (AEP) is maintained above a threshold. In some instances, maintaining AEP above a threshold supports emission control of the vehicle.

摘要： An electronic control unit carries out deceleration fuel cutoff for stopping fuel injection in an engine, and deceleration lockup for engaging a lockup clutch, at the time of deceleration of a vehicle. The electronic control unit then ends deceleration fuel cutoff and deceleration lockup upon fulfillment of a recovery condition. On the other hand, when a request to restrain heat-up of a filter device is made before fulfillment of the recovery condition, the electronic control unit stops deceleration fuel cutoff, but continues deceleration lockup.

摘要： A system includes at least one sensor coupled to an aftertreatment system and a controller having at least one processor coupled to at least one memory device storing instructions that, when executed by the at least one processor, cause the controller to perform operations. The operations include: adjusting an operating point of an engine in response to emissions information from the at least one sensor and based on a fault indicator regarding a component of the system; and, controlling an electric motor in response to the adjustment of the operating point of the engine based on a change in power output from the engine to assist in a desired emissions characteristic.
