System Description

  1. GENERAL 
    1. When the vehicle is driven at 9 km/h (5.6 mph) or less, the ultrasonic sensors detect any obstacles at the corners and rear of the vehicle. The system then informs the driver of the distance between the sensors and the obstacles as well as their positions by indicating them on the combination meter and by sounding a buzzer.
  2. FUNCTION OF COMPONENTS 
    COMPONENTS FUNCTION CHART

    Components Function
    Ultrasonic sensor The ultrasonic sensor sends and receives ultrasonic waves. Based on the received wave, the sensor calculates the approximate distance value between the vehicle and obstacle, and sends the distance value as a signal to the clearance warning ECU.
    Combination meter Transmits vehicle speed signal to clearance warning ECU. Receives information from clearance warning ECU.
    • Displays the location of an obstacle and the approximate distance between the vehicle and obstacle.
    • Informs driver if ultrasonic sensors malfunction, or if they freeze or become dirty.
    Clearance sonar main switch Built into the drive monitor switch. Outputs the system ON/OFF signals to the clearance warning ECU.
    Clearance warning ECU
    • Receives the signals from the ultrasonic sensors and sends the display signal to the combination meter.
    • Receives signals from the ultrasonic sensors and sends the display signal to the multi-display.
    • Receives signals from the ultrasonic sensors and sends the buzzer signal to the No. 1 clearance warning buzzer.
    Park/neutral position switch Sends a signal that activates the intuitive parking assist system when the shift lever is moved to R.
    Multi-display Receives the information from the clearance warning ECU through the CAN
    • Display location of obstacle and approximate distance between vehicle and obstacle.
    • Informs driver if ultrasonic sensors malfunction, or if they freeze or become dirty.
    No. 1 clearance warning buzzer Sounds the buzzer to inform the driver according to the distance to the obstacle.
    ECM Transmits shift position signal to clearance warning ECU.
    Air conditioning amplifier Transmits ambient temperature to clearance warning ECU.
    Main body ECU Transmits destination symbol, dimmer signal and steering wheel symbol to clearance warning ECU.
  3. OPERATION EXPLANATION 
    1. The clearance warning ECU determines whether the intuitive parking assist system should be operated based on the clearance sonar main switch on/off status, the shift position and the vehicle speed.
    2. When the system operates, the clearance warning ECU transmits ultrasonic waves from the ultrasonic sensors. If these waves encounter an obstacle within one or more of the sensor ranges, the waves are reflected back to the sensors, which transmit them to the clearance warning ECU. Based on this information, the clearance warning ECU sends signals to the multi-information display, the multi-display and the No. 1 clearance warning buzzer. The approximate distance between the vehicle and the obstacle is then indicated, and the buzzer sounds.
