The brake system (1) has two brake circuits with two pressure generating units, which are supplied with energy from two energy sources. A single error in the brake circuits is detected, where the faulty brake circuit is deactivated and a functional brake c...

A brake device for a vehicle is provided in which when there is an abnormality in which a slave cylinder (42) becomes incapable of being actuated, a wheel cylinder (26, 27, 30, 31) is actuated by means of a brake fluid pressure generated by a master cylind...

A slave cylinder includes a first input port (76a) which is provided to a first slave hydraulic chamber (64) and which is connected to a master cylinder (M/C) and is capable of being cut off from the master cylinder (M/C) by a shut-off valve (MCV1); a seco...

The system has a control circuit (40) receiving braking request signals (SFR) from a servo-brake (20) and from an electronic stability program control module (30) to control a solenoid valve (70) of a high pressure accumulator (60) according to braking mod...

In a braking control apparatus 100, each of a pump 7 and a pump 8 is driven by a common first motor 11. A brake ECU200 supplies operating fluid to each of pipelines H1 and H2 by operating the first motor 11, and controls opening/closing of a fluid pressure...

In a vehicle braking apparatus, a pressure control valve (50) is controlled according to a brake operation amount of a brake pedal (15) to thereby regulate hydraulic pressure and supply it to wheel cylinders (25FR, 25FL, 25RR, and 25RL). By controlling the...

A piston assembly is provided which detects and prevents binding of a piston which is always fixed in a normal state and required to move only in case of a failure of a hydraulic or pneumatic system. One end of a second piston (2) has a tubular extension. ...
