Abstract
A hydraulic braking apparatus for a motor vehicle having a service braking system (A) fed by a central hydraulic unit (3) and an emergency braking system (B). A simulator (M) resists a forward motion of an actuator member (D, 16) for a master cylinder (17) to define a reaction corresponding to the progress of a braking operation. Admission solenoid values (9a-9d) and exhaust solenoid values (14a-14d) connected to the wheel brakes (2a-2d) modulate pressurized fluid supplied by a central hydraulic unit (3) in effecting the braking operation. Sensors (8, 13a-13d, 24, 29) in the motor vehicle detect various braking parameters that are communicated to a computer (C) to control the solenoid valves (9a-9d; 14a-14d) such that the braking operation is a function of the travel of the actuator member (D, 16).
