Abstract: Methods and systems are provided for controlling a vehicle engine to adjust exhaust warm-up strategy based on a vehicle network information. In one example, in response to an expected decrease in temperature of a catalyst of a vehicle below a threshold and an estimated duration thereof based on communications external from the vehicle, a method may include delaying catalyst heating actions, when the catalyst heating actions are determined to be unable to heat up the catalyst to threshold temperatures. However, the catalyst heating actions may be enabled when the catalyst heating actions are determined to be able to achieve the threshold temperature within the duration.

Abstract: Methods and systems are provided for electrically-assisted engine braking. In one example, a method may include operating a turbocharger by an electric motor during engine braking to increase air flow to an engine intake. The enhanced air flow into the engine intake increases an exhaust manifold pressure, thus increased a braking force provided by engine braking.

Abstract: Methods and systems are provided for selecting a first travel route for a vehicle from a database based on particulate filter regeneration requirements and an inferred initial driver state of mind. In one example, the initial driver state of mind may be selected based on a past driver history, and during travel along the first travel route, the driver state of mind may be updated based on the driver interactions with traffic. The route selection may also be updated based on the updated driver state of mind.

Abstract: Methods and systems are provided for controlling boost pressure and exhaust gas recirculation in a split exhaust system. In one example, a first portion of exhaust may be routed from a cylinder to an exhaust turbine via a first exhaust valve and a second, remaining portion of exhaust may be routed as exhaust gas recirculation (EGR) via a second exhaust valve, the timing and lift of each of the first valve profile and the second valve profile adjusted based on boost error and EGR error. Further, motor torque from an electric motor may be supplied to the turbocharger to attain a desired boost pressure and a desired EGR flow.

Abstract: Methods and systems are provided for controlling a turbocharged engine. In one example, a method may include concurrently adjusting an exhaust recirculation gas flow and a turbine flow while adjusting geometry of a compressor to compensate for disturbance caused by the compressor adjustment.

Abstract: Systems and methods for controlling and diagnosing air flow through a compressor without recirculating air flow through the compressor are presented. In one example, a position of an air flow control device located within a compressor housing is adjusted responsive to a request to diagnose flow through the compressor. The diagnostic may be performed while maintaining engine torque and speed.

Abstract: Methods and systems are provided for detecting a missing exhaust catalyst based on water adsorption and related exothermic temperature rise by the catalyst. In one example, a method may include indicating an exhaust catalyst missing in response to an estimated exhaust temperature profile being different from an expected exhaust temperature profile. The estimated exhaust temperature profile may be based on exhaust temperature upstream and downstream of the catalyst.

Abstract: Systems and methods are described for coordinating the regeneration of a gasoline particulate filter to a time duration when engine output falls below a predetermined load threshold selected to indicate a low power state of the engine. In one particular example, the engine is configured to adjust engine operations to regenerate the particulate filter responsive to engine output falling below a predetermined low power threshold, the regeneration further based on an estimated duration that the output falls continuously below the low power threshold. The system and methods described advantageously allow for either full or partial regeneration events to be performed based on the estimated duration of the engine output below the low power threshold.

Abstract: Exhaust aftertreatment systems and methods are described for reducing emissions output therefrom. In one example, an exhaust gas aftertreatment system comprises a first catalyst downstream of a branchpoint in a first exhaust pathway, a second catalyst downstream of the branchpoint in a second exhaust pathway, an electrical heater positioned upstream of the branchpoint for heating the exhaust flow, a control unit for adjusting an exhaust heating current of the electrical heater, and a valve for adjusting a distribution of exhaust flow to the first and second catalyst, the control unit including instructions to adjust the valve responsive to a substrate temperature within one or more of the first and second catalysts. In this way, an exhaust system with increased efficiency across a range of operating temperatures is realized that reduces emissions and energy expended during usage.
