Introduction to the functions of pedestrian warning devices


    The pedestrian warning system can achieve the following functions:
    By collecting signals such as vehicle speed and gear position, different driving modes can emit different warning sounds;
    The sound of the two products can be composed of different frequency spectra, and can be produced through two methods: synthesized audio and recorded audio;
    The frequency spectrum of the played sound shifts and changes in sound pressure as the vehicle speed increases; 


    4. The sound can be customized, with sound selection and volume adjustment (within the standard range).
    Algorithm dependency:
    The AVAS algorithm requires real-time input of CAN information, low-speed prompt tone for frequency shift and gain calculation; The information includes vehicle speed and gear.
    The data is sent to the AVAS algorithm module via CAN.
    Determine the logic for starting AVAS and support the activation and deactivation of AVAS functions (hard and soft switches).
    Switch between customized AVAS sounds. 


    Customer Support:
    The audio source file for AVAS prompt sound can be specified.
    Regulatory debugging and certification.
    The installation location is shown in the following
