Abstract
An automobile brake control system, which applies braking force commonly to both driving wheels and restrictively controls the braking force when a specified difference occurs between a wheel speed of the driving wheel and a vehicle speed estimated based on wheel speeds of the front and rear wheels, controls, when the vehicle is traversing a split surface road, the braking force based on a wheel speed of a specific one of the driving wheels which is suffering a road surface frictional coefficient greater than another driving wheel, and corrects the vehicle speed to a lower speed according to a difference in road surface friction coefficients at the driving wheels.
