BLIND SPOT MONITOR SYSTEM


  1. FUNCTION OF MAIN COMPONENTS

    Component Function
    Blind Spot Monitor Sensor LH and RH
    • Outputs millimeter waves from the blind spot monitor sensor to the blind spot sensor detection area, uses the reflected millimeter waves for detecting the presence of a vehicle, the vehicle-to-vehicle distance, and the relative speed, and then transmits this information to the built-in signal processing circuit.

    • The signal processing circuit determines if a vehicle is present, and illuminates or blinks the outer rear view mirror indicator accordingly.

    • Dims the outer rear view mirror indicator light on the outer rear view mirror assembly.

    • Transmits the indicator light signal to the front multiplex network door ECU.

    • Transmits the RCTA signal to the rear television camera assembly.

    Outer Rear View Mirror Assembly LH and RH Outer Rear View Mirror Indicator Light
    • Illuminates to inform the driver that a vehicle has been detected in the blind spot monitor sensor detection area.

    • Flashes to inform the driver when the turn signal lever is operated if a vehicle has been detected in the blind spot monitor sensor detection area.

    • Both indicator lights flash to inform the driver that a vehicle has been detected in the blind spot detection area while the driver is reversing.

    Combination Meter Assembly Blind Spot Monitor Indicator Light Illuminates or turns off the blind spot monitor indicator light to inform the driver of the blind spot monitor system operating (on/off) status.
    Multi-information Display
    • When a malfunction is detected in the blind spot monitor sensors or the blind spot monitor sensors determine that control is not possible, the message is displayed on the multi-information display to warn the driver.

    • Displays the multi-information display screen for turning the blind spot monitor system ON/OFF, in response to operation signals of the multi-information display.

    Combination Meter Assembly Transmits the turn light signal to the blind spot monitor sensor LH and RH.
    Steering Pad Switch Assembly Transmits the operation signal to the combination meter assembly.
    Steering Sensor Transmits the steering angle signal to the blind spot monitor sensor LH and RH.
    Network Gateway ECU Relays and transmits data between CAN buses.
    ECM Transmits the reverse signal to the blind spot monitor sensor LH and RH.
    Brake Actuator Assembly Skid Control ECU Transmits the vehicle speed signal to the blind spot monitor sensor LH and RH.
    Main Body ECU (Multiplex Network Body ECU) Transmits the destination signal, illumination signal and dimmer signal to the blind spot monitor sensor LH and RH.
    Front Multiplex Network Door ECU LH and RH Transmits the indicator light signal to the outer rear view mirror assembly.
    RCTA Buzzer (Blind Spot Monitor Buzzer)* Sounds when a vehicle is detected in the blind spot monitor sensor detection area while the driver is reversing.

  2. OPERATING CONDITION


    1. Blind Spot Monitor Function


      1. The blind spot monitor function operates when all of the following conditions are met:


        • The blind spot monitor main switch is on.

        • The shift lever is in a position other than R.

        • The vehicle speed is greater than approximately 16 km/h (10 mph).

      2. The blind spot monitor function can detect vehicles in its detection areas.


        • The detection areas formed by the blind spot monitor sensor LH and RH are as shown below.

          A01QDQGC01
          *a Approximately 3.0 m (9.8 ft) *b Approximately 0.5 m (1.6 ft)
          *c Approximately 1.0 m (3.3 ft) - -

    2. RCTA Function (Models with RCTA function)


      1. The RCTA function operates when all of the following conditions are met:


        • The blind spot monitor main switch (warning canceling switch assembly) is on.

        • The shift lever is in R.

        • The speed of this vehicle is less than approximately 8 km/h (5 mph).

        • Target vehicle's speed is between approximately 8 km/h (5 mph) and 28 km/h (18 mph).

      2. The RCTA function can detect vehicles in its detection areas.


        • The system continuously measures the relative speed of an approaching vehicle and its distance. If it is determined that the approaching vehicle will cross the path of this vehicle, the Estimated Crossing Time (ECT) is calculated. When the ECT is 2.5 seconds or less, the system alerts the driver by flashing the outer rear view mirror indicator lights and sounding the RCTA buzzer (blind spot monitor buzzer).

          *a This Vehicle *b Target Vehicle (Approximately 8 km/h (5 mph))
          *c Target Vehicle (Approximately 28 km/h (18 mph)) *d Approximately 5.5 m (18.0 ft.)

  3. FUNCTION


    1. Blind Spot Monitor Function


      1. According to operation conditions, the blind spot monitor function promotes safety confirmation by using the outer rear view mirror indicator light to inform the driver that another vehicle has entered the blind spot monitor sensor detection area of this vehicle.

      2. The outer rear view mirror indicator light informs the driver that a vehicle is present in the blind spot detection area by illuminating when the turn signal light switch is not operated, and by flashing when a vehicle is present and the turn signal light switch is operated.

    2. RCTA Function (Models with RCTA function)


      1. According to operation conditions, the RCTA function promotes safety confirmation by using the outer rear view mirror indicator lights and RCTA buzzer (blind spot monitor buzzer) to inform the driver that another vehicle has entered the blind spot monitor sensor alert area of this vehicle.

      2. When this vehicle is reversing, if a vehicle enters the detection area of the blind spot monitor sensors and it is determined the vehicle will cross the path of this vehicle, the system alerts the driver by flashing the outer rear view mirror indicator lights and sounding the RCTA buzzer (blind spot monitor buzzer).
