摘要： A catalyst heating system includes a monitoring module, a mode selection module and an electrically heated catalyst (EHC) control module. The monitoring module monitors at least one of (i) a first active volume of a catalyst assembly in an exhaust system of an engine and (ii) a first temperature of a non-EHC of the catalyst assembly. The mode selection module is configured to select a non-EHC radiant heating mode and generate a mode signal based on the at least one of the first active catalyst volume and the first temperature. An EHC control module increases temperature of the EHC to an elevated temperature that is greater than a stabilization temperature based on the mode signal. The stabilization temperature is greater than a catalyst light off temperature.

摘要： A method of treating emissions from an internal combustion engine of a hybrid vehicle includes directing a flow of air created by the internal combustion engine when the internal combustion engine is spinning but not being fueled through a hydrocarbon absorber to collect hydrocarbons within the flow of air. When the hydrocarbon absorber is full and unable to collect additional hydrocarbons, the flow of air is directed through an electrically heated catalyst to treat the flow of air and remove the hydrocarbons. When the hydrocarbon absorber is not full and able to collect additional hydrocarbons, the flow of air is directed through a bypass path that bypasses the electrically heated catalyst to conserve the thermal energy stored within the electrically heated catalyst.

摘要： A powertrain system includes a hybrid transmission and an internal combustion engine coupled to an exhaust aftertreatment device. A method for operating the powertrain system includes operating the hybrid transmission to generate tractive torque responsive to an operator torque request with the internal combustion engine in an engine-off state so long as the tractive torque is less than a threshold. The internal combustion engine is operated in an engine-on state at preferred operating conditions to effect light-off of the exhaust aftertreatment device and the hybrid transmission is coincidentally operated to generate tractive torque responsive to the operator torque request when the operator torque request exceeds the threshold. The internal combustion engine is then operated in the engine-on state to generate tractive torque responsive to the operator torque request.

摘要： A method of controlling a pump supplying a fluid to a transmission includes sensing a requested power and an excess power for a powertrain. The requested power substantially meets the needs of the powertrain, while the excess power is not part of the requested power. The method includes sensing a triggering condition in response to the ability to convert the excess power into heat in the transmission, and determining that an operating temperature of the transmission is below a maximum. The method also includes determining a calibrated baseline and a dissipation command for the pump. The calibrated baseline command is configured to supply the fluid based upon the requested power, and the dissipation command is configured to supply additional fluid and consume the excess power with the pump. The method operates the pump at a combined command, which is equal to the calibrated baseline command plus the dissipation command.

摘要： A method of operating a vehicle including an engine, a transmission, an exhaust gas heat recovery (EGHR) heat exchanger, and an oil-to-water heat exchanger providing selective heat-exchange communication between the engine and transmission. The method includes controlling a two-way valve, which is configured to be set to one of an engine position and a transmission position. The engine position allows heat-exchange communication between the EGHR heat exchanger and the engine, but does not allow heat-exchange communication between the EGHR heat exchanger and the oil-to-water heat exchanger. The transmission position allows heat-exchange communication between the EGHR heat exchanger, the oil-to-water heat exchanger, and the engine. The method also includes monitoring an ambient air temperature and comparing the monitored ambient air temperature to a predetermined cold ambient temperature. If the monitored ambient air temperature is greater than the predetermined cold ambient temperature, the two-way valve is set to the transmission position.

摘要： A method of heating a cabin of a motor vehicle that includes an internal combustion engine operatively connected to an exhaust system having a catalyst, and a heating, ventilation, and air conditioning (HVAC) system is provided. The method includes detecting a request to increase temperature inside the cabin, supplying fuel and air to the engine, and motoring the engine to pump the fuel and air into the exhaust system. The method also includes heating the catalyst to combust the fuel and air inside the catalyst such that a stream of post-combustion exhaust gas is generated. The method additionally includes channeling the generated stream of post-combustion exhaust gas to the HVAC system such that a temperature of a coolant circulated through the HVAC system is increased to heat the cabin. A system configured to perform the above method is also disclosed.
