    • To determine the transverse acceleration of a vehicle, in particular as an input quantity for an electronic vehicle control system such as ABS, TCS, EBV, etc., the output signals of wheel sensors representative of the rotational behavior of the individual vehicle wheels are evaluated. The correction factors representing the differences of the tire tread circumferences of the individual wheels are determined. A short-time correction factor and a long-time correction factor KZ and LZ are produced in each case for the non-driven vehicle wheels. A difference between the long-time correction factor and the short-time correction factor of the respective wheel is determined and evaluated in a filtering and adapting circuit. The quotient KZ/LZ of the short-time correction factor and the long-time correction factor of the respective wheel is calculated, and the difference is produced between the quotients of the left and right non-driven ##EQU1## wheels. The transverse acceleration of the vehicle Q.sub.FZ is the result of the relation

    • The present invention describes a process for a vehicle including an electronic control system, which processes input signals representative of the rotational behavior of the individual wheels, and wherein the differences of the tire tread circumferences of the individual wheels are determined by way of short-time and long-time correction factors. The long-time correction factors LZ.sub.n. are determined from the differences D.sub.R1 between the short-time correction factors KZ.sub.R1 and the long-time correction factors LZ.sub.R1 of the respective wheel by averaging LM.sub.r1 the differences during a predetermined time interval and by evaluating and weighting the average value. For the quick identification of an emergency wheel, every time the vehicle engine is started, the long-time factor LZ.sub.R1 is equalled once to the short-time factor KZ.sub.R1 of the respective wheel, if simultaneously the short-time correction factors of three wheels are approximately equal and the short-time correction factor of the fourth wheel adopts a relatively high value, which is within a predetermined range, for a predetermined time interval or minimum time interval, and if the short-time correction factor of the fourth wheel remains approximately constant during this time interval.

    • A method of monitoring a brake system which is equipped with anti-lock control (ABS) and a system for electronic control of brake force distribution (EBV). The system includes two brake circuits in a black/white brake circuit split-up, the EBV function or control is principally released only when the vehicle deceleration exceeds a predetermined limit value (GWN). To identify a front-axle brake circuit failure, acceleration criteria, i.e., criteria responsive to the acceleration behavior of the vehicle wheels, are predetermined and monitored. Further, slip range monitoring in conjunction with acceleration range monitoring is performed. Upon `detection` of an acceleration criterion or when a limit value (GW2) predetermined as an acceleration criterion is exceeded, and/or upon `detection` of values which are outside the slip range (GW1) or the acceleration range (GW5), a `suspected` front-axle brake circuit failure is signaled, and intervention into the electronic control of the brake force distribution (EBV) is performed.

    • A method for controlling an anti-lock braking system, intended for motor vehicles having all-wheel drive, electric signals representative of the rotational behavior of the vehicle wheels are produced and logically combined. When a locking tendency occurs, the braking pressure is controlled, and the instantaneous wheel slip, the wheel acceleration, and the wheel deceleration are evaluated as control criteria, and wherein the individual wheel speed is compared to a vehicle reference speed which is used as a reference quantity for controlling the braking pressure. In the event of a wheel rotational behavior that is typical of a spinning tendency and is revealed by a rise of the vehicle reference speed in excess of the actual vehicle speed, the control concept is modified up to a defined point of time in that the instantaneous wheel slip is left out of account as a control criterion for this spinning phase and the braking pressure control becomes dependent on merely the wheel acceleration or the wheel deceleration.

    • In a method for the adaptive control of the hydraulic pump of a brake system containing low pressure accumulator (NDS1,2) which take up the pressure fluid discharged in the case of control from the wheel brakes and which are evacuated by the hydraulic pump (HP), first the brake pressure pattern (pR) is determined for each individual wheel with the aid of a wheel pressure model. Then a volume model (VM1,2) is formed on the basis of the wheel pressure model for each individual brake circuit, which volume model indicates, by way of approximation, the filling level of the low pressure accumulators (NDS1,2). The maximum filling level (MaxV) and the control frequency or the time interval (T) between two successive brake pressure decreasing phases (Ph2) are determined. The delivery capacity of the hydraulic pump (HP) is so dimensioned that the time interval (T) between two successive brake pressure decreasing phases (Ph2) is just adequate for completely evacuating the low pressure accumulators (NDS1,2).
