Problems solved by technology

[0003] Therefore, audio system diagnostics may not be able to perform a diagnosis when the audio system is being used by, for example, a vehicle occupant, since interference caused by the vehicle occupant or the vehicle itself may cause interference and an incorrect diagnosis

Abstract

A method for diagnosing an audio system in a vehicle comprising generating (101) an audio signal of a particular frequency for at least one speaker in the audio system, transmitting (102) the generated audio signal to a compare function in the audio system in response to the generating of the audio signal, outputting (103) the generated audio signal in the at least one speaker in the audio system, receiving (104) the outputted audio signal in at least one microphone in the audio system, transmitting (105) the received audio signal to the compare function in the audio system in response to the receiving of the audio signal, determining (106) by the compare function a similarity between the generated and the received audio signal, and setting (107) a confidence level on the determined similarity based on a current operational mode of the vehicle.

Description

Technical field [0001] The present disclosure generally relates to the field of audio diagnosis in the vehicle. More specifically, it involves diagnosing an audio system in a vehicle. Background technique [0002] Vehicles typically include an audio system that includes a plurality of speakers and microphones. The audio system accepts diagnostics, in the diagnosis, the speaker outputs the test sound in each speaker. Therefore, the current audio system diagnosis depends on the test sound received by the speaker and received by the microphone. The signal strength of the test sound needs to be heard clearly, so that the diagnosis can be used only at the end of the line (i.e., during production test), because the interference must be held at a minimum. [0003] Therefore, when the audio system is being used, for example, the audio system diagnosis may not be able to perform diagnosis because interference caused by the vehicle occupant or the vehicle itself can cause interference and ...
