    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 detecting faulty wheel speed sensors. The invention relates to a driving situation detection system for monitoring and analyzing driving situations of a vehicle, for instance, straight-ahead driving, cornering and the like. The driving situation detection system is characterized in that driving situations are monitored and analyzed in said driving situation detection system with almost stationary courses of the vehicle with a streering angle speed smaller than/ equal to 120°/s, wherein the driving situation detection system is built as a state automatic machine that recognizes at least one of the states straight-ahead driving with partial braking, cornering with partial braking and/or cornering with load changes. A controller is activated depending on the states showing deviation from course.

    摘要: The invention relates to a method for regulating driving stability of a vehicle, wherein it is determined, in the presence of a stabile or unstable driving behaviour whether a tendency to a subsequently unstable driving behaviour occurs as a result of a highly dynamic inward swerve in the presence of a tendency of a consequent unstable driving performance. In order to provide a method for regulating driving stability, which allows a reaction to predicted unstable driving situations by means of an intervention diminishing critical driving situation or avoiding said situation, the steering power and/or the steering angle of a steering wheel is corrected in such a way that the driver is assisted in the operation thereof in the direction of an understeering vehicle course.
