  • Systems and methods for controlling exhaust gas aftertreatment sensor systems
    Patent number: 11905867
    Abstract: An exhaust gas aftertreatment system includes: a first sensor configured to measure a parameter in the exhaust gas aftertreatment system; a second sensor configured to measure the parameter in the exhaust gas aftertreatment system, the second sensor disposed proximate the first sensor; and at least one controller configured to alternately receive sensor values from the first sensor for a first target period of time, and receive sensor values from the second sensor for a second target period of time.
    Type: Grant
    Filed: May 10, 2022
    Date of Patent: February 20, 2024
    Assignee: Cummins Emission Solutions Inc.
    Inventors: Nathan A. Ottinger, M. Yusuf Khan, Z. Gerald Liu, Shirish Ambadas Shimpi
  • Systems and methods for controlling exhaust gas aftertreatment sensor systems
    Patent number: 11795848
    Abstract: An exhaust gas aftertreatment system includes: a first sensor configured to measure a parameter in the exhaust gas aftertreatment system; a second sensor configured to measure the parameter in the exhaust gas aftertreatment system, the second sensor disposed proximate the first sensor; and at least one controller configured to simultaneously receive sensor values from the first sensor and receive sensor values from the second sensor.

  • Systems and methods for controlling exhaust gas aftertreatment sensor systems
    Patent number: 11346264
    Abstract: An exhaust gas aftertreatment system includes a first sensor configured to measure a parameter and a second sensor disposed proximate the first sensor and configured to measure the parameter. The system includes a controller configured to initially utilize the first sensor as a primary sensor. At target intervals, the controller is configured to receive a first sensor value from the first sensor and receive a second sensor value from the second sensor. The controller is configured to calculate a difference between the first sensor value and the second sensor value and determine if the difference between the first sensor value and the second sensor value is greater than a threshold value. If the difference between the first and second sensor values is greater than the threshold value, the controller is configured to stop utilizing the first sensor as the primary sensor and utilize the second sensor as the primary sensor.
