EPB ECU Safety concept

  • The EPB ECU is based on a 2 processor concept
  • 2 different micro processors calculate and control the actuation demand (diversity).
  • The switch signal is read and checked for validity by each processor independently.
  • Any actuation will only be processed when both processors calculate the same actuation demand.
  • The control demands of each processor will be compared via an inter-processor communication line. Each processor has the ability to disable the actuation in case of a fault.
  • Both actuators will be controlled independently and are separately fused.

Key features which may be incorporated into the TRW Electric Parking Brake system:

  • Drive away assist upon vehicle acceleration, the park brake releases
  • Hill Hold prevents vehicle rollback on a hill until the driver accelerates
  • Brake wear sensing alerts the driver to worn pads
  • Interface between the Electric Parking Brake switch and accelerator pedal prevents false-apply
  • Automatic parking brake function when driver’s door is opened
