ACTIVE REAR WING SYSTEM SYSTEM DESCRIPTION


  1. ACTIVE REAR WING SYSTEM DESCRIPTION


    1. Manual operation

      The rise/retract operation of the active rear wing can be operated manually by pressing the spoiler control switch.

    2. Automatic operation


      1. Auto rise/retract operation

        When the vehicle reaches the specified vehicle speed for the selected driving mode, the active rear wing will rise/retract automatically.

        Tech Tips


        • When not in ECO mode: The active rear wing rises at approximately 80 km/h (50 mph) and retracts at approximately 40 km/h (25 mph).

        • When in ECO mode: The active rear wing rises at approximately 130 km/h (81 mph) and retracts at approximately 40 km/h (25 mph).

      2. Resume operation

        If the vehicle is stopped with the active rear wing in the fully raised position, the active rear wing will retract automatically the next time the vehicle speed reaches approximately 25 km/h (16 mph) or more. If the vehicle is stopped with the active rear wing not in the fully raised position or fully retracted position, the active rear wing will rise automatically the next time the vehicle speed reaches approximately 25 km/h (16 mph) or more.

    3. Auto rise/retract operation permission/prohibition

      If the spoiler control switch is operated at vehicle speed near the vehicle speed specified for the auto rise or retract operation, the active rear wing may rise/retract repeatedly.

      To prevent this from happening, automatic operation will be temporarily prohibited when the spoiler control switch is operated at the vehicle speeds shown in the table below and will return to normal when the conditions shown in the "Auto Rise/Retract Operation Return Condition" column of the table are met.

  2. FUNCTION OF MAIN COMPONENTS

    Item Function
    Spoiler control ECU assembly

    • Determines the active rear wing condition (raised/retracted) based on the active rear wing assembly position signal sent from the rear spoiler motor assembly and sends operation signals to the rear spoiler motor assembly to raise/retract the active rear wing in accordance with the active rear wing condition, vehicle speed and selected driving mode.

    • Sends operation signals to the rear spoiler motor assembly to raise/retract the active rear wing in accordance with the signal sent from the spoiler control switch.

    • Sends active rear wing assembly position signals to the combination meter assembly via CAN communication.
    Rear spoiler motor assembly

    • Receives signals from the spoiler control ECU assembly and raises/retracts the active rear wing assembly.

    • Detects the position of the active rear wing assembly using built-in Hall ICs and sends active rear wing assembly position signals to the spoiler control ECU assembly.

    No. 4 combination switch assembly

    (Spoiler control switch)

    • Sends a signal to the spoiler control ECU assembly when operated.

    • Has an indicator light which illuminates when the active rear wing is not in the fully retracted position and turns off when the active rear wing is in the fully retracted position to inform the driver the active rear wing condition.
    Main body ECU (Multiplex network body ECU) Sends luggage compartment door open/closed signals to the spoiler control ECU assembly via CAN communication.
    ECM Sends the driving mode signal to the spoiler control ECU assembly via CAN communication.
    Skid control ECU assembly Sends the vehicle speed signal to the spoiler control ECU assembly via CAN communication.
    Combination meter assembly

    • The multi-information display in the combination meter assembly can be used to change active rear wing system permission/prohibition setting.

    • Sends active rear wing system permission/prohibition signals to the spoiler control ECU assembly via CAN communication.
