摘要： Methods, systems, devices and apparatuses for a sound enhancement system. The sound enhancement system includes a trailer brake control unit placed on the vehicle and an electronic control unit coupled to the trailer brake control unit. The electronic control unit is configured to determine the vehicle is operating in a tow mode based on the trailer brake status, determine a magnitude of an audio signal that mimics or enhances engine sound based on the tow mode, and generate the audio signal. The sound enhancement system further includes an audio device configured to output the audio signal based at the determined magnitude.

摘要： Methods, systems, devices and apparatuses for a sound enhancement system. The sound enhancement system includes an airflow sensor. The airflow sensor is configured to measure an airflow into an engine of the vehicle. The sound enhancement system includes an electronic control unit. The electronic control unit is coupled to the airflow sensor. The electronic control unit is configured to determine a time of when to output an audio signal that mimics or enhances engine sound based on the airflow into the engine of the vehicle. The electronic control unit is configured to generate the audio signal based on the airflow into the engine of the vehicle. The sound enhancement system includes an audio device. The audio device is configured to output the audio signal based on the timing of when to output the audio signal.
