摘要： The invention relates to a method for operating a hydraulic brake system for a vehicle and a hydraulic brake system wherein said method is carried out. The aim of the invention is to provide a reliable default plane such that the wheel brakes are impinged upon by hydraulic pressure by the hydraulic pump according to the sensor system which detects actuation or according to the pressure sensor, in the event of a failure in the high pressure accumulator. Another advantage of said invention is that the amplification chamber is impinged upon by hydraulic pressure from the high pressure accumulator in the event of a failure of the pump, according to the sensor system which detects actuation or according to the pressure sensor.

摘要： The invention relates to a hydraulic vehicle braking system comprising a hydraulic brake-pressure transducer, which essentially consists of a brake master cylinder (11) and a hydraulic servo unit (7), connected upstream of said cylinder. The pressure of said transducer can be exerted on the wheel brakes of the vehicle. In order to boost the braking force, the hydraulic pressure transducer can be subjected to the hydraulic pressure of an electronically controllable external pressure source (4, 19, 20), which is connected to the hydraulic servo unit (7) via a conduit (50), in which an analog or analogised valve (5) is situated. The hydraulic pressure transducer is connected via a conduit (12, 12.2) to a hydraulic fluid storage tank (13), which is in turn connected to the electronically controllable external pressure source (4, 19, 20) via a conduit (12.1, 12), in which an additional analog or analogised valve (6) is situated. The brake actuation device is hydraulically-mechanically decoupled from the hydraulic system in normal operation. In addition, the braking system is equipped with a simulator (61) that co-operates with the brake actuation device and a unit that identifies the driver's deceleration intention (60, 64) and the electronically controllable external pressure source (4, 19, 20) can be controlled according to the identified driver's deceleration intention (brake-by-wire system).

摘要： The invention relates to a method for detecting a critical brake operation of a two-track vehicle during cornering, comprising the following steps: detecting the rolling performance of a left-side and a right-side wheel; comparing the rolling performance and/or evaluating the time response of at least one left-side or right-side wheel, and detecting critical brake operation on the basis of comparison and/or evaluation results. The braking pressure of an internal cornering wheel can be reduced in response to detection. The device for detecting a critical brake operation of a two-track vehicle during cornering has a sensing device (403a, b, 408a, b) for detecting the rolling performance of a left-side or right-side wheel (301a-d), a first comparison device (409-412) to compare the rolling performance and/or an evaluation device (404-407) to evaluate the time response of at least one left-side or right-side wheel and a sensing device (413) to detect a critical brake operation on the basis of the output of the comparison device and/or the output of the evaluation device. A changing device (315) can also be provided to reduce the braking pressure of an internal cornering wheel in response to detection.

摘要： The invention relates to a method for operating a hydraulic vehicle-braking system. Said method is characterised in that a hydraulic pressure is fed directly to a brake-master cylinder (11) via a hydraulic booster (7), which is connected upstream of said cylinder, and that the hydraulic pressure is regulated in accordance with a variable that represents the braking request of the driver. To achieve the latter, the pressure in the hydraulic booster (7) that is located upstream of the brake-master cylinder is regulated by controlling at least two valves (6) that are similar or that operate in a similar manner.

摘要： The invention relates to a method for improving the control performance of a vehicle control system, e.g. an antiskid braking system (ABS), a driving stability control system (ESP, ASMS, FDR), etc. According to said method, whenever a wheel becomes unstable and the ABS control system becomes operational, the relevant lines (18) of the control system to which the unstable wheel is connected are partially disengaged from the master cylinder pressure (pHZ) or the admission pressure in a braking system, which comprises a master cylinder (1), inlet and outlet valves (5-8) for pressure modulation, a low-pressure storage (9) and a hydraulic pump (10) to feed back the derived hydraulic medium, by closing the hydraulic medium path in the direction leading from the wheel brakes (3, 4) to the master cylinder (1). By feeding back the hydraulic medium from the low-pressure storage (9) a relatively faster buildup of the braking pressure is produced in said line (18) and the wheel braking pressure quickly approximates the master cylinder pressure (pHZ) and thus a blocking pressure level. A special valve (14) which can produce a connection between the master cylinder (1) and the intake side of the hydraulic pump (10) is switched only after the at least partial emptying of the low-pressure storage occurs (9) or when through flow is required.
