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 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 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 a compressor having a variable inlet device and an active casing treatment. In one arrangement, a system for a compressor may include a casing forming a recirculation passage surrounding an inlet passage, an active casing treatment surrounding the inlet passage and configured to selectively control gas flow through the recirculation passage, an impeller, and a variable inlet device positioned in the inlet passage upstream of the impeller and configured to selectively reduce an effective size of the impeller. The variable inlet device and the active casing treatment may be adjusted based on operating conditions in order to increase a flow range of the compressor while providing high compressor efficiency.

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.
