A vehicle and method reduce heating of a particulate filter during a regeneration event in response to an accelerator pedal tip-out and particulate filter temperature exceeding or anticipated to exceed a threshold by fueling the engine to reduce oxygen in the exhaust flowing to the particulate filter. An electric machine may be operated as a generator charging a battery to compensate or offset torque produced by the fueling of the engine. The current or anticipated particulate filter temperature may be estimated by a soot combustion model for a current regeneration event and/or a future regeneration event based on soot loading of the particulate filter.

Reducing heating of a particulate filter during a regeneration event

A system and method for providing torque-assist to a rotary shaft of an internal combustion engine control an electric machine in response to operation of an exhaust gas recirculation (EGR) valve to assist the rotation of the rotary shaft. The system and method facilitate periodic operation of the EGR valve to purge condensation without objectionable torque reduction when the engine is operating near full load.

Method and system for providing torque-assist

A vehicle and method for controlling a vehicle having a variable displacement engine with an auxiliary machine connected directly to the engine crankshaft and to an energy storage device includes switching from a cylinder disablement (VDE) mode to a normal mode when the torque demand and engine speed lie outside an outer range defined by a first threshold (T), and switching from the normal mode to the VDE mode when the torque demand and engine speed lie within an inner range, which lies within the outer range and defined by a second threshold (T). When operating in a band between the two thresholds, the auxiliary machine draws energy from the energy storage device and supplements the output torque from the engine if operating in the VDE mode, and derives torque from the engine crankshaft to recharge the energy storage device if operating in the normal mode.

Vehicle and method of controlling a vehicle

An exemplary method of providing torque-assist to a crankshaft of an internal combustion engine includes, among other things, assisting a rotation of the crankshaft using an electric machine during the transition between stages of a multi-stage forced induction system.
