摘要： A slip control system determines friction/slip characteristics of tires of a road vehicle equipped both with an antilock system to permit an individual brake pressure control on individual vehicle wheels. The front wheel brakes are connected to a primary output pressure space of the tandem master cylinder, and the rear wheel brakes are connected to a secondary output pressure space of the tandem master cylinder. A first bore stage of a housing of the tandem master cylinder forms a housing-defined boundary of the secondary output pressure space. An inner piston flange movably seals off a pressureless downstream chamber in relation to an inner portion of the first bore stage. An intermediate wall of the housing delimits the bore stage relative to a central bore stage which extends from a third bore stage receiving a primary piston. An actuating piston is displaceably guided in the central bore stage in a pressure tight manner and forms an axially movable, inner boundary of the primary output pressure space relative to a pressureless downstream chamber in the central bore stage which is bounded by the intermediate wall. An annular space is bounded in an axially movable manner by an inner piston flange of a secondary piston and by the intermediate wall and is connected to the pressure output of the controllable pressure source.

摘要： The present invention relates to a method for determining a friction coefficient value (Fμ) which represents the coefficient of friction present between the underlying surface and a vehicle tire. For this purpose, a wheel slip value (λij) is determined for at least one vehicle wheel, said value (λij) describing the wheel slip present at this vehicle wheel. The friction coefficient value (Fμ) is determined as a function of this wheel slip value (λij). For this purpose, during a predefined operating state of the vehicle wheel slip values (λij) are determined at various times, in particular successive times. The frequency distribution of values is determined for these wheel slip values (λij) or for axle-related slip values (λVA and λHA) which are determined as a function of these wheel slip values (λij). The friction coefficient value (Fμ) is determined by evaluating this frequency distribution of values.

摘要： In a method and apparatus for determining the curvature of a curve passing through a plurality of points, the shape of which is defined by a line connecting these points, curvature is assigned to the individual points by determining the position of adjacent points relative to the individual points. The curvature of a point (B) is determined by further taking into account two additional points (A, C), one of which (A) lies on the connecting line forward of the respective point (B) and the other (C) on the connecting line behind the respective point (B). The points (A, C) are determined such that they are as remote as possible from the respective point (B) and, at the same time, no points exist which lie between the respective point (B) and one of the additional points (A, C), and which are farther than a set distance from the connecting lines between the respective point (B) and each of the two additional points (A, C).

摘要： For the determination of the friction/slip characteristics of the tires of a road vehicle which is equipped with an antilock system designed for an individual wheel control, in an initial phase of a controlled braking, only the wheel brake of an individual vehicle wheel is acted upon by brake pressure and the latter is dimensioned so that the result is the initial retardation in accordance with the driver's wish. During this initial test phase of the braking, the absolute brake slip .lambda..sub.B as well as the friction utilization .mu..sub.B linked therewith is continuously determined as soon as, as a result of just the braking of the test wheel, the vehicle retardation z increases no further and/or the braked vehicle wheel is more strongly retarded than corresponds to a predetermined threshold value, the test braking is interrupted and the braking is continued by pressure action on the further vehicle wheels; corresponding test braking phases are carried out in cyclic sequence for all guidance wheels.

摘要： A brake system has a variable front/rear axle braking force distribution for a racing car. An electrohydraulic braking force control device with an electronic computer stage is provided in the system to take account of the aerodynamic axle load changes occurring at high speeds. This computer stage forms, from the vehicle speed and dynamically determined magnitudes, or magnitudes assumed to be appropriate, of the coefficient of friction .mu..sub.B effective at the vehicle wheels, an optimized braking force distribution factor. The brake pressure connected into the rear wheel brakes is caused to follow up the brake pressure connected into the front wheel brakes in such a way that the rear axle braking force follows the front axle braking force.
