BLIND SPOT MONITOR SYSTEM SYSTEM DESCRIPTION


  1. GENERAL


    1. The blind spot monitor system has the blind spot monitor function and rear crossing traffic alert function.


      1. Blind spot monitor function


        • The blind spot monitor function is a function that assists the driver in making the decision to change lanes. The function uses quasi-millimeter wave radar to detect vehicles that are traveling in an adjacent lane in the area that is not reflected in the outer rear view mirror assembly. The function advises the driver of the existence of a vehicle by illuminating the outer rear view mirror indicator on the outer rear view mirror assembly.

        • If the turn signal switch is operated while the outer rear view mirror indicator on an outer rear view mirror assembly is illuminated, the indicator starts blinking to give additional warning to the driver.

      2. Rear crossing traffic alert function


        • The rear crossing traffic alert function is a function that informs the driver of an approaching vehicle from diagonally behind. The function uses quasi-millimeter wave radar to detect the positions of and relative speed to a vehicle. When the function determines that a vehicle is approaching this vehicle, this function informs the driver of it using the outer rear view mirror indicators and blind spot monitor buzzer.

  2. FUNCTION OF COMPONENTS

    Component Function
    Blind Spot Monitor Sensor

    • Consists of a 24 GHz radar module and an integrated processing module.

    • Illuminates or blinks the outer rear view mirror indicator on the outer rear view mirror assembly.

    • Sounds the rear crossing traffic alert buzzer (blind spot monitor buzzer) when the rear crossing traffic alert function is operating.

    • Changes the outer rear view mirror indicator on the outer rear view mirror assembly from illuminated to blinking when a turn signal switch operation signal is received from the combination meter assembly with the blind spot monitor function operating.

    • Dims the outer rear view mirror indicator on the outer rear view mirror assembly and blind spot monitor indicator on the blind spot monitor main switch (warning canceling switch assembly).

    • Turns on the blind spot monitor indicator on the blind spot monitor main switch (warning canceling switch assembly) when the blind spot monitor main switch (warning canceling switch assembly) is on.

    Outer Rear View Mirror Assembly


    • Outer Mirror (Outer Rear View Mirror Indicator)

    		 Turns on or blinks the indicator based on a signal from the blind spot monitor sensor.

    Blind Spot Monitor Main Switch (Warning Canceling Switch Assembly)


    • Blind Spot Monitor Indicator

    • Turns the blind spot monitor system on or off.

    • Informs the state of the blind spot monitor system by illuminating the blind spot monitor indicator.
    Rear Crossing Traffic Alert Buzzer (Blind Spot Monitor Buzzer) Sounds based on a signal from the blind spot monitor sensor.

    Combination Meter Assembly


    • Multi-information Display

    • Transmits a turn signal switch operation signal from the headlight dimmer switch assembly to the blind spot monitor sensor via CAN communication.

    • Displays an error message on the multi-information display if the blind spot monitor detects a malfunction while it is operating.
    Main Body ECU (Multiplex Network Body ECU) Transmits the destination information and the dimmer signal to the blind spot monitor sensor via CAN communication.
    Skid Control ECU Assembly Transmits a vehicle speed signal to the blind spot monitor sensor via CAN communication.
    Hybrid Vehicle Control ECU Assembly Transmits a shift position signal (R) and HV flag signal to the blind spot monitor sensor via CAN communication.
    Spiral Cable with Sensor Sub-assembly Detects the angle of the steering wheel and transmits the resulting signals to the blind spot monitor sensor via CAN communication.
    Yaw Rate and Acceleration Sensor Transmits the yaw rate signal to the blind spot monitor sensor via CAN communication.

    Rear Television Camera Assembly*1

    Radio Receiver Assembly*2

    		 Receives the blind spot monitor sensor information via CAN communication and sends it to the multi-display assembly through the video signal cable.
    Multi-display Assembly Receives the video signals from the rear television camera assembly, and displays RCTA icon on the display panel.

  3. OPERATION DESCRIPTION


    1. Operation description of the blind spot monitor function


      1. Operation conditions:


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

        • Vehicle speed is more than approximately 16 km/h (10 mph).

      2. Conditions in which a sensor can detect a vehicle

        The blind spot monitor function indicates detection of a vehicle in the detection area when either condition is met:


        • When a vehicle is detected in an adjacent lane overtaking this vehicle.

        • When a vehicle is detected entering the detection area because it changed lanes.

    2. Operation description of the rear crossing traffic alert function


      1. Operation conditions:


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

        • The shift lever is in R.

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

      2. Conditions in which a sensor can detect a vehicle

        The rear crossing traffic alert function indicates detection of a vehicle in the detection area when both conditions are met:


        • A vehicle is approaching this vehicle from diagonally behind.

        • The vehicle speed is approximately 8 km/h (5 mph) to 28 km/h (17 mph).

    1. Initial check


      1. When the blind spot monitor main switch (warning canceling switch assembly) is turned on with the power switch on (IG), the outer rear view mirror indicators on the outer rear view mirror assembly illuminate for 3 seconds and the rear crossing traffic alert buzzer (blind spot monitor buzzer) sounds for 1 second.

      2. When the power switch is turned from off to on (IG) with the blind spot monitor main switch (warning canceling switch assembly) on, the outer rear view mirror indicators on the outer rear view mirror assembly illuminate for 3 seconds.

    2. Operation for each function
