Failure detection and backup system for pneumatic braking system
  • Year:2016
  • Project:DOIT Program
  • Category:Other categories technology
  • Technique Features:

    A failure detection and backup system is provided for the pneumatic braking system. Several pressure sensors and displacement sensors are installed in the baking system to detect the pressure and pressure buildup condition of the pipes and the tanks. The measured parameters are then used to determine the failure reason or components when the air is leaked, and the controller alarms the driver through the light on the dashboard. A backup system is developed to provide additional braking to help the driver to stop the vehicle and reduce the risk of hitting other vehicle and roadside objects.

  • Specification:

    1.Failure detecting time:0.1Sec.
    2.Failure detection items:Leakage of pipe or tank, abnormal of compressor and cylinder.
    3.Backup system operating pressure:6~10 kg/cm2.
    4.Backup system operating times:5.

  • Applications:

    Vehicle pneumatic braking system.

  • Benefit:

    The developed techniques could help finding the failure reasons and alarming the driver, and provide additional braking chances to rise the driving safety.
