DRIVING SURFACE FRICTION ESTIMATIONS FOR VEHICLES

Systems, methods, and an autonomous vehicle are provided. One aspect of the present disclosure relates to a computer-implemented method comprising receiving a request for a friction estimation associated with a driving surface upon which the autonomous vehicle is traveling. The method further comprises detecting an event including at least one of an acceleration, a deceleration, or a stop associated with the autonomous vehicle based at least in part on at least one of map data, motion planning data, or route planning data associated with the autonomous vehicle; performing a wheel-based action in response to the request; obtaining, in response to detecting the event, operational data associated with the wheel-based action of the autonomous vehicle during the event; determining, based at least in part on the operational data, data indicative of the friction estimation; and controlling the autonomous vehicle based at least in part on the data indicative of the friction estimation.
