Abstract: An after-treatment (AT) system used to treat an exhaust gas flow emitted by an internal combustion engine includes a catalyst monolith configured to actively remove a pollutant from the exhaust gas flow. The AT system also includes a heating element configured to heat the catalyst monolith. The AT system additionally includes an energy-discharge unit configured to power the heating element. The energy-discharge unit includes an energy-storage device configured to supply electrical energy. The energy-discharge unit also includes a capacitor configured to receive the electrical energy from the energy-storage device and discharge the received electrical energy to power the heating element and thereby heat the catalyst monolith. A vehicle having an internal combustion engine operatively connected to such an AT system is also contemplated.

Abstract: A method for fault-tolerant coasting control of a powertrain system having an engine and a first energy storage system (ESS) includes receiving a real impedance value of the first ESS from a frequency analyzer device at a calibrated frequency while the engine is running, and comparing the real impedance value to a calibrated impedance. A coasting maneuver is enabled allowing the engine to turn off above a threshold speed when the real impedance value is less than the calibrated impedance. The method may include starting the engine using a second ESS in parallel with the first ESS to exit the coasting maneuver when the real impedance value exceeds the calibrated impedance. Subsequent execution of the coasting maneuver may be prevented as long as the real impedance value exceeds the calibrated impedance. A powertrain system includes the engine, starter motor, rechargeable ESS, frequency analyzer, and controller.

Abstract: In a vehicle, a first energy storage device has a first direct current (DC) operating voltage; and a second energy storage device has a second DC operating voltage. The second DC operating voltage is greater than or less than the first DC operating voltage the first DC operating voltage. A switch is connected between the first and second energy storage devices. A fault diagnostic module, while an internal combustion engine of the vehicle is shut down, diagnoses that a fault is present when a voltage of the first energy storage device is less than a predetermined DC voltage. The predetermined DC voltage is less than the first DC operating voltage. A switch control module closes the switch when the fault is diagnosed. A starter control module, when the fault is diagnosed, applies power to a starter from the second energy storage device via the switch.
