A braking system for a vehicle includes a hydraulic vehicle brake with an electric actuator and an electromechanical braking device. The braking system further includes a locking mechanism configured to lock the electric actuator.

Braking system for a vehicle having a hydraulic vehicle brake and an electromechanical braking device

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. In so doing, a pressure quantity representing the admission pressure is estimated, at least one operating state of at least one actuator in the braking system is detected and the wheel braking pressure is estimated as a function of the estimated admission pressure and the detected operating states.

Method and device for determining the pressure in brake systems

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.

Method and device for determining a value representing the system pressure in a brake circuit

A control system for motor vehicles in which the errors in wheel velocities created by tolerances between the tires are compensated.

Motor vehicle control system and method

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.

Method for improving the controllabilty of motor vehicles

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.

System and method for controlling the dynamics of vehicle movement

Method for setting target braking torques

In a method for braking motor vehicle wheels, to reduce a yawing moment produced by an antilock braking system, the build-up of braking pressure on at least one wheel is influenced. The braking pressure on the wheels of one axle is influenced to such an extent that the differential between the braking pressures of one axle does not exceed a maximum permissible value. This maximum permissible value is made dependent upon the vehicle speed and the transversal acceleration.
