A controller for an autonomous vehicle receives audio signals from several microphones. The source of the audio features is classified and a direction to a sound source is determined. If the class of the sound source is a parked vehicle then a collision avoidance module is programmed to avoid a potential path of that vehicle. The source of the audio features may be classified using a machine learning model, and the direction to the source may be determined based on relative delays of the audio features in signals from multiple microphones. The direction to the source of the audio features may be correlated with vehicle images and/or map data to increase a confidence score that the source of the audio features is a parked vehicle with its engine running. The collision avoidance module may control the autonomous vehicle to avoid collision with the source of the audio features.
