    • An anti-lock brake system (ABS) for a road vehicle is equipped with a wheel slip control system (ASR) and a hydraulic dual circuit brake system having front axle/rear axle brake static brake circuits, one brake circuit being allocated to the driven (rear) wheels of the vehicle and one to the non-driven (front) wheels. The system has two high-pressure pumps, one for each of the two brake circuits and which, in control phases of the ABS, brake fluid can be fed into the output pressure spaces of the brake unit and wherein the high-pressure pump allocated to the rear axle brake circuit is also utilized as auxiliary pressure source for the ASR. At the front axle brake circuit, the ABS operates on the feedback principle and at the rear axle brake circuit it operates on the discharge principle.

    • In a drive slip control device for a road vehicle, which is provided with an anti-lock system operating on the pump-back principle and having a return pump of the anti-lock system associated with the brake circuit of the driven vehicle wheels used as the auxiliary pressure source for the drive slip control, for braking a vehicle wheel tending to spin. When the drive slip control is activated, the main brake pipe of the brake circuit of the driven vehicle wheels is shut off from the brake unit by means of a drive slip control valve. The return pump is activated and is shut off from the brake unit until the drive slip of one of the driven vehicle wheels exceeds a threshold value whose magnitude lies between the drive slip required value and threshold response value. The brake pressure control valves of the brake circuit of the driven vehicle wheels are driven into their closed position by means of this anticipatory activation of the return pump. This causes high pressure to build up in the main brake pipe, which is limited to a value of the anti-lock braking system and of the brake equipment by means of a pressure limiting valve, which is then available for an introductory brake pressure build-up phase of the drive slip control on the vehicle wheel requiring it. An additional outlet valve, by means of which the return line of the rear axle of the anti-lock system can be directly connected to the brake fluid reservoir, can be provided for controlling the pressure reduction phases.

    • A drive control device for a motor vehicle with rear axle drive and equipped with an anti-blocking system. As part of a rotational speed sensor arrangement provided to determine the state of movement of the vehicle wheels, each of the non-driving front wheels has an associated rotational speed sensor and the two rear wheels have a common rotational speed sensor, which measures the rotational speed of the propeller shaft in the transmission system. A hydraulic actuator provided for brake pressure control corresponds in construction to that of a 4 channel anti-blocking system. These components are utilized for both the drive control and the anti-blocking control. An electronic control system of the drive control device, which processes the output signals of the rotational speed sensors, initially activates the right-hand rear wheel brake, as soon as a driving wheel starts to spin. If the vehicle does not accelerate in consequence or if, indeed, there is a deceleration of the vehicle, switching occurs to the left-hand driving wheel brake either with a time delay or immediately. If necessary, both driving wheel brakes are activated with a time delay and the engine torque withdrawn. In the case of travel around a curve, the control cycle is introduced by braking the driving wheel on the inside of the curve.

    • A process for anti-lock control on a racing vehicle having an aerodynamic design which results, at high speeds, in a clear increase both of the front-axle load and the rear-axle load of the vehicle. On a wheel requiring control, the response of the anti-lock control is triggered in the direction of a brake-pressure reduction when an axle-related reference quantity K.sub.h or K.sub.v, formed as a sum of weighted amounts of the wheel-circumference deceleration Z and of the brake slip of the respective vehicle wheel related to a reference speed, exceeds a threshold value. At least during the formation of the reference quantity critical for the front axle, the reciprocal value of the locking limit, determined with inclusion of negative lift forces and air resistance, of the vehicle wheels, plus a safety value .DELTA.Z.sub.o, is taken as a weighting factor X.sub.v. Within the framework of an anti-lock system suitable for carrying out the process, a brake unit switchable to different values of the brake-force distribution under the control of its electronic control unit is provided.

    • An anti-blocking system for a road vehicle having a hydraulic service brake installation constructed as a dual-circuit brake installation with a front axle/rear axle brake circuit distribution which is adjustable to different values m.sub.1 and m.sub.2 of the front axle/rear axle braking force distribution, whereby the one value m.sub.1 corresponds to a braking force distribution optimized in the sense of driving stability and the other value corresponds to a relatively higher value of the rear axle braking force proportion. As long as the regulation is effective only at the rear axle, this anti-blocking system operates according to the principle of keeping a braking slippage .lambda..sub.H occurring in the rear axle brake circuit within the range of values delimited by the relation .lambda..sub.V +.DELTA..lambda..ltoreq..lambda..sub.H .ltoreq..lambda..sub.V +.DELTA..lambda. in relation to a braking slippage .lambda..sub.V occurring in the front axle brake circuit, whereby .DELTA..lambda. designates a permissive slippage differential of about 4% and .DELTA..lambda.'.apprxeq..DELTA..lambda./2. As soon as the anti-blocking regulation is also effective on the front axle, both the latter and the rear axle are regulated according to the principle of keeping both the front axle braking slippage .lambda..sub.V and the rear axle braking slippage .lambda..sub.H within the same range of values delimited by an upper limit of the braking slippage which is compatible with good braking deceleration and equally good driving stability.
