    摘要： The invention relates to a vacuum brake booster and a method for operating a vacuum brake booster (1) of a vehicle brake system, comprising a housing (5) which is subdivided into at least one vacuum chamber (3) and at least one working chamber (2) by means of at least one movable partition (4). The vacuum chamber (3) is joined to a vacuum source via a vacuum connection (10) while a sensor unit is assigned to the vacuum chamber (3). The sensor unit (6) senses the pressure in the vacuum chamber (3) and feeds the same to an electronic control unit (11) which encompasses an evaluation unit for evaluating the pressures sensed in the vacuum chamber (3) and calculates the control point of the vacuum brake booster solely based on the pressure prevailing in the vacuum chamber (3). A plausibility check of the pressure value measured by the sensor unit (6) is performed in order to support the monitoring process of the entire system, potential defects of the sensor unit (6) or the vacuum brake booster (1) being determined during said plausibility check.

    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 modifying a driving stability control of a vehicle according to which the input variables that substantially consist of the predetermined steering angle (δ) and the speed (v) are converted to a desired value of the yaw velocity (γdesired) on the basis of a vehicle model determined by handling characteristics, and said desired value is compared with a measured actual value of the yaw velocity (γ¿measured?). According to the result of said comparison, an additional yaw angle (MG) is calculated in an ESP controller, said yaw angle being used to determine an ESP intervention which produces an additional yaw angle via pressure values that are applied to the wheel brakes of the vehicle. Said additional yaw angle gradually brings the measured yaw velocity (γ¿measured?) up to the calculated yaw velocity (γdesired). To this end, a model-based friction coefficient is determined whose output signals (ν) are fed to the vehicle model and are thus taken into consideration in the calculation of the desired value of the yaw velocity (γdesired). In order to prevent the vehicle from rolling over about its longitudinal axis, the friction coefficient is limited depending on values that reflect at least one threshold transversal acceleration or a value derived therefrom to a value below the maximum admissible friction coefficient (νmax).

    摘要： The invention relates to a method for determining correction values for the wheel speeds of a vehicle, comprising the following steps: determining the speeds of the vehicle wheels during travel, said vehicle wheel speeds being evaluated in groups for at least one vehicle axle and at least one vehicle side; and determining the correction values for the individual vehicle wheels according to the results of the evaluation. The invention also relates to a device for determining correction values, comprising wheel sensors (111-114) for detecting the speeds of the vehicle wheels (101-104) during travel and a device (230, 601-607) which evaluates the vehicle wheel speeds in groups for at least one vehicle axle and at least one vehicle side and determines the correction values for the individual wheels of the vehicle according to the results of this evaluation.
