ASC SYSTEM SYSTEM DESCRIPTION


  1. ASC SYSTEM


    1. The ASC system uses the stereo component equalizer assembly to generate dynamic engine sounds electronically. These sounds are output from the No. 1 speaker assembly with box. The dynamic engine sounds are calculated in accordance with vehicle information, such as the drive mode, engine speed and accelerator pedal opening angle. By operating the vehicle sound switch, the sounds can be turned on/off and volume can be adjusted.

    2. The following sounds are generated.

      Sound Description
      Additional Engine Sounds

      • Specially designed engine sounds which are synchronized with the engine speed and output when the vehicle is being driven.

      • Generated when the vehicle speed is 6 km/h (4 mph) or more and engine speed is 980 rpm or more.

      1. Additional engine sounds generation conditions

        Item Condition Remark
        Drive mode NORMAL or SPORT mode In NORMAL mode, only some of the additional engine sounds will be generated
        Shift lever position R, D, M -
        Vehicle speed 6 km/h (4 mph) or more When all of the conditions are met, additional engine sounds are generated.
        Engine speed 980 rpm or more

  2. FUNCTION OF MAIN COMPONENTS

    The ASC system consists of the following components:

    Component Function
    Stereo component equalizer assembly

    • Receives signals, such as accelerator pedal opening angle, engine speed, driving mode and drive force, from the ECM via CAN communication and creates dynamic engine sounds.

    • Sends a dynamic engine sound signal to the No. 1 speaker assembly with box.
    No. 1 speaker assembly with box Outputs simulated driving sounds into the cabin according to the signal sent by the stereo component equalizer assembly.
    Vehicle sound switch

    • Sends an ASC system on/off signal to the stereo component equalizer assembly.

    • Adjusts the volume of the dynamic engine sounds output by the No. 1 speaker assembly with box.
    ECM Sends signals, such as accelerator pedal opening angle, engine speed, driving mode and drive force to the stereo component equalizer assembly via CAN communication.
    Skid control ECU assembly Sends vehicle speed signals to the stereo component equalizer assembly via CAN communication.
