Abstract
A road surface condition determining system for an automotive vehicle equipped with a traction control feature determines, while the traction control is being executed, a first road surface friction coefficient on the basis of a vehicle speed and longitudinal acceleration and a second road surface friction coefficient on the basis of driving torque applied to the driving wheels and selects, as an eventual road surface friction coefficient, either one of the first and second road surface friction coefficients which is larger than the other.
