Abstract: A vehicular airborne particulate detection system in one embodiment includes a particulate matter concentration sensor positioned in a passenger space of a vehicle. The particulate matter concentration sensor generates a signal associated with an airborne particulate matter concentration in the passenger space which is analyzed by a controller to identify a cyclical particulate matter concentration pattern which is classified as a smoking event. The controller then generates an output using a user interface based upon the classified smoking event.

Abstract: A system for detecting vehicle body damage is disclosed. One or more ultrasonic transceivers are installed on a portion of the vehicle body and configured to transmit and receive ultrasonic sound waves. One or more controllers are coupled to the one or more ultrasonic transceivers. The one or more controllers are programmed to cause the ultrasonic transceiver to emit first ultrasonic sound waves and receive first reflected ultrasonic sound waves, store in memory first sound signature data relating to the first reflected ultrasonic sound waves, cause the ultrasonic transceiver to emit second ultrasonic sound waves and receive second ultrasonic sound waves, and determine a presence of damage on the portion of the vehicle body based on second sound signature data relating to the second reflected ultrasonic sound waves deviating from the first sound signature data.
