Abstract: An example sensor system for use with a vehicle includes a first group of sensing devices that are associated with an essential level of autonomous operation of the vehicle. The first group of sensing devices are configured and intended for continuous use while the vehicle is being autonomously operated. The sensor system further includes a second group of sensing devices that are associated with a non-essential level of autonomous operation of the vehicle. For example, the second group of sensing devices are configured to be redundant to and/or to enhance the performance of the first group of sensing devices. The second group operates in response to certain conditions being determined during autonomous operation of the vehicle. The sensor system further includes a plurality of assemblies attached to the vehicle. Each assembly includes two or more sensing devices from the first group and/or the second group.

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.

Abstract: An autonomous vehicle includes audio sensors configured to detect audio in an environment around the autonomous vehicle and to generate audio signals based on the detected audio. A processor in the autonomous vehicle receives the audio signals and compares a time domain or frequency domain representation of the audio signals to a corresponding representation of a known emergency vehicle siren. The comparison causes the processor to output a first determination indicating whether the audio signals are indicative of an emergency vehicle siren. The processor also applies a trained neural network to the audio signals that causes the processor to output a second determination indicating whether the audio signals are indicative of the emergency vehicle siren. If the first determination or the second determination indicates presence of an emergency vehicle siren in the environment around the autonomous vehicle, the autonomous vehicle is caused to perform an action.
