Us Patents

  • Egr Valve Position Control System

    view source
  • US Patent:
    6467469, Oct 22, 2002
  • Filed:
    Jan 31, 2001
  • Appl. No.:
    09/773040
  • Inventors:
    Chang Yang - West Bloomfield MI
    Gregory R. White - Columbus IN
    Robert S. Henrich - Columbus IN
    Yue Yun Wang - Columbus IN
    John M. Janssen - Nashville IN
    Ray C. Hatton - Columbus IN
  • Assignee:
    Cummins, Inc. - Columbus IN
  • International Classification:
    F02M 2507
  • US Classification:
    12356821, 12356816
  • Abstract:
    An EGR valve position control system includes an EGR valve manager responsive to an EGR valve command to drive an EGR valve actuator. The EGR valve manager is operable to schedule control gains as a function of valve actuation direction to provide for faster response during valve closing events. Valve closing events are also staged such that a large valve position step is followed by a steady ramp to the valve closed position to thereby prevent damage to the valve and/or valve seat. The EGR valve manager further includes a prioritized switching feature for strategically switching between closed and open loop control modes, and a forward gain adjustment feature responsive to battery voltage to maintain constant system DC gain under changing battery voltage conditions.
  • Throttle Miswire Detection

  • US Patent:
    6543415, Apr 8, 2003
  • Filed:
    Sep 9, 2002
  • Appl. No.:
    10/237752
  • Inventors:
    Ross Pursifull - Dearborn MI
    Chang Yang - Farmington Hills MI
  • Assignee:
    Visteon Global Technologies, Inc. - Dearborn MI
  • International Classification:
    F02D 100
  • US Classification:
    123396, 123399
  • Abstract:
    A throttle miswire detection system including a powertrain control module (PCM) coupled to a throttle actuator and a pair of throttle plate position sensors. In detecting miswires, the PCM sets the throttle plate to a default position in which a default position value is measured by the position sensors. The PCM then sets the throttle plate to a closed position in which a closed position value is measured by the position sensors. After recording the receiving measurements, the PCM computes a negative slope sensor difference and a positive slope sensor difference. The PCM calculates a slope ratio consisting of the positive slope sensor difference divided by the negative slope sensor difference. If the slope values or slope ratio are not within prescribed limits, then the PCM deactivates the throttle actuator.
