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 outer mirror control ECU assembly.

    • Transmits the RCTA signal to the rear television camera assembly.
    Blind Spot Monitor Main Switch (Warning Canceling Switch Assembly) Pressing the blind spot monitor main switch (warning canceling switch assembly) turns the blind spot monitor system on or off.
    Blind Spot Monitor Main Switch (Warning Canceling Switch Assembly) Blind Spot Monitor ON/OFF Indicator Light When the blind spot monitor system is on, the indicator will come on.
    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 Master Warning Light When a malfunction is detected in the blind spot monitor sensors or the blind spot monitor sensors determine that control is not possible, the master warning light illuminates and a message is displayed on the multi-information display to warn the driver.

    Combination Meter Assembly Transmits the turn light signal to the blind spot monitor sensor LH and RH.
    Steering Sensor Transmits the steering angle signal to the blind spot monitor sensor LH and RH.
    Yawrate Sensor Outputs yawrate information to the blind spot monitor sensor LH and RH.
    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.
    Outer Mirror Control ECU Assembly (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.
    Rear Television Camera Assembly

    • Captures images of the area behind the vehicle.

    • The RCTA icon is superimposed on the captured image. Then, the image is sent to the multi-display assembly as video signals.
    Multi-display Assembly Receives visual signals from the rear television camera assembly, and displays them.

  2. SYSTEM CONTROL


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


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

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

      3. 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.


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

        B004H2SC01
        *a Approximately 3.5 m (11.5 ft) *b Approximately 60 m (197 ft)
        *c Approximately 3.0 m (9.8 ft) *d Approximately 1.0 m (3.3 ft)
        B004H7E Detection Area (for Vehicle in Blind Spot) B004GZL Detection Area (for Rapidly Approaching Vehicle from Behind)

        Tech Tips

        If another vehicle that is rapidly approaching the vehicle's blind spot is detected, the notification timing is determined by the relative speed of the approaching vehicle. The notification timing for vehicles rapidly approaching the vehicle's blind spot can be customized. For details, refer to the Repair Manual.

      2. Detection Area (for Vehicle in Blind Spot)


        • When this vehicle is overtaken by another vehicle in an adjacent lane.

          B004HAOC03
          *a This Vehicle - -
          B004H73 Vehicle Speed (Fast) B004HAI Vehicle Speed (Slow)
          B004H7E Detection Area - -

        • When another vehicle enters the detection area of this vehicle due to a lane change.

          B004H26C03
          *a Other vehicle enters the detection area during lane change (merge in) (Type 1). *b Other vehicle enters the detection area during lane change (merge in) (Type 2).
          *c This Vehicle - -
          B004H73 Motion direction of this vehicle B004HAI Motion direction of other vehicle
          B004H7E Detection Area - -

      3. Detection Area (for Rapidly Approaching Vehicle from Behind)


        • When another vehicle is rapidly approaching from behind.

          B004H39C01
          *a This Vehicle - -
          B004H73 Vehicle Speed (Fast) B004HAI Vehicle Speed (Slow)
          B004GZL Detection Area - -

        • When another vehicle enters the detection area of this vehicle due to a lane change and approaches this vehicle.

          B004H5JC01
          *a Other vehicle enters the detection area during lane change (merge in) (Type 1). *b Other vehicle enters the detection area during lane change (merge in) (Type 2).

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


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

      2. The shift lever is in R.

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

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

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


      1. 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).

        B004HA4C01
        *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.)
        *e Approximately 20 m (66 ft.) *f Target Detection Line

      2. Normal Parking

        B004HBZC01
        *a This Vehicle *b Target Vehicle
        B004GZL Alert Area - -

    5. 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 the system detects vehicles that are in or rapidly approaching the vehicle's blind spot.

    6. The outer rear view mirror indicator light illuminates when a vehicle is in or rapidly approaching the vehicle's blind spot and the turn light switch is not operated. The indicator light flashes when a vehicle is in or rapidly approaching the vehicle's blind spot and the turn light switch is operated.

    7. 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.

    8. 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).

  3. DIAGNOSIS


    1. The blind spot monitor system is equipped with a diagnosis function that can display warning messages in the multi-information display. For details, refer to the Repair Manual.
