Abstract: A system includes an exhaust aftertreatment system coupled to an engine, and a controller including at least one processor coupled to at least one memory device storing instructions that, when executed by the at least one processor, cause the controller to perform certain operations. The operations include estimating an aging of the exhaust aftertreatment system, and adjusting at least one of an entry temperature threshold or an exit temperature threshold for a thermal management mode for the exhaust aftertreatment system based on the aging of the exhaust aftertreatment system.

Abstract: An aftertreatment system includes a first oxidation catalyst, a second oxidation catalyst, and a turbocharger. The first oxidation catalyst is upstream of the turbocharger and includes a first oxidation catalyst formulation. The second oxidation catalyst is downstream of the turbocharger and includes a second oxidation catalyst formulation different than the first oxidation catalyst formulation. The second oxidation catalyst formulation is configured to promote conversion of nitric oxide (NO) to nitrogen dioxide (NO2).

Abstract: Disclosed are methods, systems, and computer-readable mediums for predicting a driving intention of a driver of a vehicle. A sequence comprising a plurality of indicators is detected, where each indicator suggests intent to drive a vehicle. A separation time between each of the indicators of the sequence is determined. The sequence and determined separation times are compared to historical data, where the historical data comprises data related to previously stored separation times of the sequence. Based on the comparison, a confidence level that an engine of the vehicle will be started is determined. Based on the confidence level, a feature of the vehicle is activated.

Abstract: Systems, apparatus and methods are provided for reducing reductant consumption in an exhaust aftertreatment system that includes a first SCR device and a downstream second SCR device, a first reductant injector upstream of the first SCR device, and a second reductant injector between the first and second SCR devices. NOx conversion occurs with reductant injection by the first reductant injector to the first SCR device in a first temperature range and with reductant injection by the second reductant injector to the second SCR device when the temperature of the first SCR device is above a reductant oxidation conversion threshold.

Abstract: A method includes acquiring nitrogen oxide (NOx) data indicative of a first amount of NOx in an exhaust flow exiting an engine and a second amount of NOx in the exhaust flow exiting an exhaust aftertreatment system coupled to the engine where the exhaust aftertreatment system including a selective catalytic reduction (SCR) system including a SCR catalyst; determining a NOx conversion efficiency fault is present within the exhaust aftertreatment system based on the first amount of NOx and the second amount of NOx; monitoring an actual amount of NOx in the exhaust flow downstream of the SCR catalyst; determining an expected amount of NOx downstream of the SCR catalyst; and determining the SCR catalyst is responsible for the NOx conversion efficiency fault in response to the actual amount of NOx differing from the expected amount of NOx by more than a threshold amount.
