Abstract
An electronically controlled braking system is disclosed and includes a brake servo valve for controlling brake pressure in response to an electrical brake actuating signal having a value which is controlled by a brake command circuit and a skid control circuit. The brake command circuit provides a brake command signal which is representative of the brake pressure determined by an operator or by an automatic braking system. The brake command signal is modified as a function of the skid control circuit output to provide the electrical brake actuating signal which is supplied to a valve driver for actuating the brake control coil of the brake servo valve.
