    Abstract: A system and method for controlling brake pressure is described wherein desired brake pressures are determined. From these pressures, valve activation control times are calculated and thus the pressure is directed into the wheel brake cylinders. The wheel brake cylinder pressures are determined from the activation times of the valves and the brake circuit pressure. They are also used for determining the desired pressure. In addition a pump is provided which makes it possible to generate higher pressures in the wheel brake cylinders than those actuated by the driver. The brake circuit pressures required for the above-described determination of the desired pressure are determined by calculating a model and using the measured inlet pressure.

    Abstract: In a vehicular control system in which target braking torques are set for each of the driven wheels, the smaller target braking torque for the driven wheels is determined. Based on this smaller target braking torque, a target engine torque is calculated, and the engine torque is varied to conform to the target engine torque. Residual braking torques are calculated as differences from the target braking torques for each driven wheel and the target engine torque. These residual braking torques are realized by varying the brake pressure. Therefore the target braking torque is split into an engine torque which is equal for both driven wheels and into a braking torque which may be different for each driven wheel.

    Abstract: A method for improving the controllability of motor vehicles during braking wherein desired slip values are determined and adjusted with the aid of a wheel slip controller. According to the method, the following are measured: the yaw rate .psi., the steering angle .delta., the wheel speeds V.sub.Ri, the inlet pressure P.sub.inlet or wheel brake pressure P.sub.i, and, if required, the engine speed and the throttle valve angle. The following variables are estimated using the measured values: the longitudinal vehicle speed V.sub.X, the longitudinal vehicle acceleration V.sub.X, the wheel slip values .lambda..sub.i, the braking forces F.sub.Bi, the tire forces F.sub.Ri, and the transverse speed V.sub.Y. Desired slip values .lambda..sub.i * are then determined from these measured and estimated variables with the aid of a simple vehicle model and supplied to the slip controller to control the vehicle wheel brake pressure.

    Abstract: Device and method for determining a wheel braking pressure and/or an admission pressure in a braking system in which pressure medium is introduced from a reservoir for the pressure medium having an admission pressure into a wheel brake through at least one shutoff device for inlet and/or outlet and/or passage of a pressure medium, it being possible to remove pressure medium from the wheel brake through at least one means delivering the pressure medium.

    Abstract: Brake pressure is varied briefly by means of pressure pulses at regular intervals during phases when brake pressure is otherwise maintained constant, and any variations in transverse acceleration at each axle are determined. These variations at the axles are used to modify the wheel slip by varying the brake pressure in order to increase stability while retaining an adequate steerability reserve or vice versa.

The two values are divided ##EQU1## and the resulting values is used for determining the slippage.

    Abstract: A method and a device for determining a quantity describing the brake circuit pressure, with which the brake circuit pressure is determined for a pressure buildup, in particular a pressure buildup independent of the driver, and also for a pressure reduction. In a pressure buildup independent of the driver, the delivery performance of the pump which delivers the brake medium and is detected with sensing means is taken into account in determining the brake circuit pressure. In a pressure reduction, the brake circuit pressure is determined as a function of a quantity which describes the brake circuit pressure to be expected after the pressure reduction.
