A method for controlling an electro-hydraulic brake system includes the steps of determining an expected pressure of the brake system, determining the actual pressure of the brake system, and comparing the actual pressure to the expected pressure. If the a...

A vehicular hydraulic-pressure-generation device wherein a first bush compressively deforms due to pressure from a simulator piston that moves when hydraulic pressure produced when a brake pedal is depressed is transmitted into a cylinder part. Said vehicu...

A hydraulic brake booster system. The hydraulic brake booster system includes a primary piston axially moveable within a bore of a cylinder, a booster chamber located rearwardly of the primary piston within the bore, an input rod extending within the boost...

The unit (47) has a brake pressure sensor (2) and a pressure control device (1) arranged for adjusting pressure in a controlling chamber (22) of the brake pressure sensor. The pressure control device is hydraulically connected with the brake pressure senso...

A hydraulic controller includes: a pair of liquid chambers; and an on-off valve (116,117) capable of opening and closing a flow channel (152,159) on the side of the liquid chamber with a higher hydraulic pressure (143,130) out of the pair of liquid chamber...

The device has a master cylinder (13) with a hydraulic piston (95) defining a pressure chamber (7) connected to brakes arranged at levels of wheels. A hydraulic servomotor (11) has a hydraulic piston (15) dividing a chamber (5) into front and rear chambers...
