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 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： A travel control apparatus is provided with: a speed controller that controls speed of a vehicle having an internal combustion engine; and a determination part that determines an emission deterioration state of the internal combustion engine. The speed controller is configured to execute burn-and-coast control that repeatedly executes burn control in which the vehicle is accelerated by driving force of the internal combustion engine, and coasting control in which the vehicle is driven by inertia, by stopping the generation of the driving force or rotation of the internal combustion engine. The speed controller is configured to execute emission suppression control that suppresses emissions by adjusting the burn-and-coast control when the emission deterioration state of the internal combustion engine is determined by the determination part.

摘要： Methods and systems are provided for controlling hybrid vehicle engine operation, where the vehicle engine comprises one or more cylinders dedicated to recirculating exhaust to an intake manifold. In one example, during an engine cold-start event or other event where temperature of one or more exhaust catalysts are below a temperature needed for catalytic activity, fuel injection to the dedicated exhaust gas recirculation cylinder(s) is maintained shut off, while its intake and exhaust valves are maintained activated, thus enabling the dedicated exhaust gas recirculation cylinder(s) to route air to the intake manifold of the engine, resulting in exhaust gas lean of stoichiometry that may serve to heat the catalyst. In this way, during cold start events and other events where temperature of one or more exhaust catalysts are below a temperature for catalytic activity, combustion stability issues may be avoided, and exhaust catalyst(s) rapidly heated, thereby reducing undesired tailpipe emissions.

摘要： A method for starting and operating an engine of a mild hybrid vehicle following start-up is disclosed for an engine having low and high voltage starting devices, and controlled by an electronic controller. The method comprises using the high voltage starting device as a motor to crank the engine whenever possible so as to partially discharge a high voltage battery. The method further comprises using the high voltage starting device as a generator after starting the engine if the exhaust gas temperature needs to be increased so as to assist with light-off of one or more exhaust gas after treatment devices.

摘要： A hybrid vehicle includes an internal combustion engine, a filter, an electrical storage device, a rotating electric machine, and a controller. The filter is configured to trap particulate matter in exhaust gas of the internal combustion engine. The rotating electric machine is configured to generate electric power using power from the internal combustion engine so as to charge the electrical storage device, and drive the internal combustion engine using electric power from the electrical storage device. The controller is configured to control the internal combustion engine and the rotating electric machine, so as to warm up the electrical storage device when regeneration control needs to be performed and when the temperature of the electrical storage device is lower than a reference value. The regeneration control is control for raising the temperature of the filter to a predetermined temperature so as to burn the particulate matter. The controller may be configured to execute the regeneration control when the temperature of the electrical storage device exceeds the reference value.
