In an anti-lock braking apparatus, by detecting brake torque at a wheel and controlling the braking force of a wheel brake unit, a locked state of the wheel can be quickly detected to thus enable braking control with fast response characteristics. Also, based on direction of a variation of the brake torque on the wheel, the road friction coefficient is predicted to perform feedback control for the braking force and to adjust the brake torque to a target brake torque, whereby the braking performance can be optimized.

A control system for automatic transmission is provided in a motor vehicle having an internal combustion engine and an automatic transmission associated with the engine. The engine is operable on a fuel which is a mixture of gasoline and alcohol. The control system comprises an alcohol sensor for sensing the alcohol concentration in the fuel; a first device for deriving an engine load parameter which represents the load applied to the engine; a second device for correcting the engine load parameter with reference to the alcohol concentration sensed by the alcohol sensor; and a third device for controlling a line pressure of the transmission in accordance with the corrected engine load parameter.
