Abstract: Disclosed are devices, systems and methods for detecting road surface conditions. One exemplary system installed in a vehicle comprises: an audio sensor configured to receive audio signals associated with an environment surrounding the vehicle; a location sensor configured to detect a location of the vehicle; a digital signal processor communicatively coupled to the audio sensor and configured to estimate an estimated road surface condition based on the audio signals received from the audio sensor; a data storage communicatively coupled to the digital signal processor and the location sensor and configured to store the estimated road surface condition with corresponding location information; and a control element communicatively coupled to the data storage and configured to control a driving of the vehicle based on the estimated road surface condition.
