Methods and apparatus for determining tire/road coefficient of friction
A vehicle control method includes iteratively modifying a level of braking of the vehicle until it is determined that the vehicle has substantially lost traction with respect to the road surface, then determining the coefficient of friction between the road surface and the tire based on the level of braking at the time the vehicle substantially lost fraction. In one embodiment, previous ABS or other vehicle control events are used as a basis for estimating an initial level of braking to be applied during the friction measurement procedure. Such a deterministic maneuver can also function as a collision warning to the driver of the vehicle.
