Abstract
A system is provided wherein road surface friction is sensed by measuring strain on a structure of a vehicle in a vicinity of a wheel of the vehicle. A road surface friction coefficient is determined by measuring strain on a structure of the vehicle in the vicinity of the wheel to produce signal outputs proportional to road surface frictional force and vertical load, and calculating the road surface friction coefficient from the outputs.
