US Patent 9688194 In-vehicle particulate sensor data analysis

A vehicle may include particulate sensors configured to generate particulate data indicative of size and quantity of ambient particulates. The vehicle may also include a computing device configured to receive the particulate data from the at least one particulate sensor, compare the particulate data to a signature data identifying a particulate condition, and adjust a vehicle setting to address the particulate condition or alert the user of the particulate condition. A server may receive a route request from a vehicle over a communications network, the route request specifying a destination location for a vehicle and an indication of signature data descriptive of particulate to avoid; construct a route avoiding the particulate according to particulate data received from a plurality of vehicles and including location metadata and time metadata; and send the route to the vehicle responsive to the request.
