  • Publication number: 20250100569
    Abstract: Presented herein are systems and methods for performing federated learning across vehicles. A computing device having one or more processors coupled with memory can maintain, on the memory, a first machine learning (ML) comprising a first plurality of parameters for determining values identifying a characteristic of a vehicle function on at least one of a plurality of vehicles. The computing device can receive a second plurality of parameters generated by a second ML used by each respective vehicle. The computing device can update the first plurality of parameters of the first ML in accordance with the second plurality of parameters received from each respective vehicle of the plurality of vehicles. The computing device can transmit, to a vehicle, the updated first plurality of parameters to update the second plurality of parameters of the second ML on the vehicle.

  • Publication number: 20240337209
    Abstract: A system includes a controller having at least one processor coupled to a memory storing instructions that, when executed by the at least one processor, causes the controller to: receive data indicative of operating conditions of at least one of an engine or of an aftertreatment system; determine, during a first period of time, that an amount of NOx output from the aftertreatment system satisfies a low NOx operating mode condition based on the data indicative of operating conditions; determine, during a second period of time, that operating conditions for a conversion efficiency are present based on the data indicative of the operating conditions of the aftertreatment system; determine that the amount of NOx output from the aftertreatment system satisfies a high NOx operating mode condition; and selectively set an alert based on a retrieved minimum value and a retrieved maximum value of the amount of NOx outputs.

  • Patent number: 12044155
    Abstract: A method for diagnosing a NOx sensor is provided. The method includes receiving data indicative of operating conditions of an engine or an aftertreatment system; determining, during a first period of time, that an amount of NOx output from the aftertreatment system satisfies a low NOx operating mode condition; determining, during a second period of time, that operating conditions for ammonia slip are present based on data regarding operation of the aftertreatment system; responsive to the determination that operating conditions for ammonia slip are present, determining that the amount of NOx output from the aftertreatment system satisfies a high NOx operating mode condition; comparing a difference between a minimum value from the first period of time and a maximum value from a second period of time to a diagnostic threshold; and responsive to the difference being less than the diagnostic threshold, setting an alert.
