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 an 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 an 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 an 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.

    • Displays the rear crossing traffic alert icon on the multi-display when the rear crossing traffic alert function is operating.

    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.
    Steering Pad Switch Assembly Enables, disables or cuts off the operation of the blind spot monitor system by transmitting switch operation signals to the combination meter assembly.
    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 sensors via CAN communication.

    Brake Actuator Assembly


    • Skid Control ECU

    		 Transmits a vehicle speed signal to the blind spot monitor sensors via CAN communication.
    ECM Transmits a shift position signal (R) and HV flag signal to the blind spot monitor sensors via CAN communication.
    Steering Sensor Detects the angle of the steering wheel and transmits the resulting signals to the blind spot monitor sensors via CAN communication.

    Airbag Sensor Assembly


    • Yaw Rate and Acceleration Sensor

    		 Transmits the yaw rate signal to the blind spot monitor sensor via CAN communication.

    • Parking Assist ECU*1

    • Television Camera Assembly*2

    		 Receives the blind spot monitor sensor information via CAN communication and sends it to the multi-display through the video signal cable.

    • Navigation Receiver Assembly*3

    • Radio and Display Receiver Assembly*4

    • Receives the video signals from the television camera assembly, and displays rear crossing traffic alert icon on the display panel.

    • Receives the video signals from the parking assist ECU and displays rear crossing traffic alert icon on the display panel.

  3. OPERATION DESCRIPTION


    1. Operation description of the blind spot monitor system


      1. Operation conditions:


        • The blind spot monitor system 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.

    2. Operation description of the rear crossing traffic alert function


      1. Operation conditions:


        • The blind spot monitor system 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 from the right or left at the rear of the vehicle.

        • The vehicle speed is approximately 8 km/h (5 mph) to 28 km/h (18 mph).

  4. OPERATION OF OUTER REAR VIEW MIRROR INDICATOR AND REAR CROSSING TRAFFIC ALERT BUZZER (BLIND SPOT MONITOR BUZZER)


    1. Initial check


      1. When the blind spot monitor system is turned on with the ignition switch ON, the outer rear view mirror indicators on the outer rear view mirror assembly illuminate for 3 seconds.

      2. When the ignition switch is turned from off to ON with the blind spot monitor system on, the outer rear view mirror indicators on the outer rear view mirror assembly illuminate for 3 seconds.

    2. Operation for each function


      1. 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.

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