METHOD FOR ESTIMATING TIRE GRIP

A method for estimating a grip of a tire (12) supporting a vehicle (14) is disclosed. The method comprises the steps of: generating a first set of data (82) from a tire-mounted sensor unit (26); generating a second set of data (84) from the tire-mounted sensor unit (26) and from data obtained from the vehicle (14); generating a third set of data (86) from data obtained from the vehicle (14) and from the internet; providing a grip estimation module (50); receiving the first, second and third sets of data (82, 84, 86) in the grip estimation module (50); calculating a friction probability distribution (88) with the grip estimation module (50) using the first, second and third sets of data (82, 84, 86); and inputting the friction probability distribution (88) into at least one vehicle system.
