BLIND SPOT MONITOR SYSTEM SYSTEM DESCRIPTION


  1. GENERAL


    • The blind spot monitor system 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. 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.

    • 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 system 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 Rear View Mirror (Outer Rear View Mirror Indicator)

    		 Turns on or blinks the indicator based on a signal from the blind spot monitor sensor.
    Outer Mirror Control ECU Assembly Receives a signal from the blind spot monitor sensor and sends the signal to the outer rear view mirror indicator on the outer rear view mirror assembly.

    Blind Spot Monitor Main Switch (Warning Canceling Switch Assembly)


    • Blind Spot Monitor Indicator

    • Turns the blind spot monitor system on or off.

    • Inform the state of the blind spot monitor system by illuminating the blind spot monitor indicator.

    Combination Meter Assembly


    • Multi-information Display

    • Sends 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) Sends the destination information and the dimmer signal to the blind spot monitor sensor via CAN communication.

    Brake Actuator Assembly


    • Skid Control ECU

    		 Transmits a vehicle speed signal to the blind spot monitor sensor via CAN communication.
    ECM Sends 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 sends the resulting signals to the blind spot monitor sensor via CAN communication.

  3. OPERATION DESCRIPTION


    1. Operation description of the blind spot monitor system


      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 system 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.

        *a Vehicles in the following areas can be detected:
        *b Within approx. 3.5 m (11.49 ft) from the side of the vehicle
        *c Within approx. 3 m (9.85 ft) behind the rear bumper
        *d Within approx. 1 m (3.29 ft) forward of the rear bumper

        Detection area

        Vehicles in the following areas can be detected:

  4. OPERATION OF OUTER REAR VIEW MIRROR INDICATOR


    1. Initial check


      1. When the blind spot monitor main switch (warning canceling switch assembly) is turned on with the engine switch on (IG), the outer rear view mirror indicator on each outer rear view mirror assembly illuminates for 3 seconds.

      2. When the engine 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 indicator on each outer rear view mirror assembly illuminates for 3 seconds.

    2. Operation for the blind spot monitor system

        Operation for blind spot monitor system


        • When a sensor detects a vehicle in the blind spot area, the outer rear view mirror indicator on the outer rear view mirror assembly illuminates.

        • While the sensor is detecting a vehicle in the detection area and the indicator is illuminated, if the turn signal switch is operated, the outer rear view mirror indicator on the outer rear view mirror assembly starts blinking as shown in the illustration.
