The evolution of the IVI(In-Vehicle Infotainment System) underscores the escalating significance of extending connectivity beyond rudimentary audio and video playback capabilities, which are aimed at optimizing passenger safety and convenience. Sound anomalies within the IVI system are increasingly recognized as technically significant. However, the complex nature of audio features makes manual evaluation challenging. In this paper, we present an MSVS(Mobis Sound Verification Solution), which is an automated sound testing tool that can detect subtle sound irregularities. When utilizing this solution to test audio capabilities, it enables real-time verification of silent intervals and detection of any pop noise within the incoming audio signals. Moreover, through the application of deep learning in the target signal detection feature, it is possible to determine the currently playing audio signal. To evaluate the performance of the MSVS, a simulation environment comparative to an actual vehicle was established to reproduce and evaluate various problems occurring in the IVI. |
