Abstract

In one embodiment, a system and method are provided for detecting a slip condition between a vehicle tire and a road surface, processing contemporaneous vehicle data, such as torque or brake pressure applied, to determine a force of friction, and calculating a coefficient of friction. The coefficient of friction and location of the slip are broadcast to other vehicles driving in the proximity of the slip. The broadcasts may be utilized to notify drivers of slippery driving conditions at or ahead of the vehicle, and/or to limit torque and braking pressure applied to vehicle wheels to enhance traction and avoid slip.
