Parking Distance Warning (PDW) Description And Operation

  • PDW consists of 8 sensors (front : 4 units, rear : 4 units) that are used to detect obstacles and transmit the result in three separate warning levels, the first, second and third to BCM via LIN communication.
  • BCM decides the alarm level by the transmitted communication message from the slave sensors, then operates the buzzer or transmits the data for display.
