Abstract: A brake system for a motor vehicle has electromechanical wheel brakes, a brake operating unit and a central brake control unit. The wheel brakes each have a local brake control unit. The central brake control unit is connected to the brake operating unit and the local brake control units via a first data connection. The brake operating unit is connected to the local brake control unit of at least one wheel brake via a second data connection. In a normal operating mode the central brake control unit determines at least one brake demand from first operating information, received via the first data connection and transmits control signals corresponding to the brake demand to the local brake control units. In a fallback operating mode the local brake control units actuate the respective wheel brakes basis on second operating information, received via the second data connection.

Abstract: In a method and apparatus for stabilizing running of a wobbling trailer towed by a vehicle, a tandem of trailer and vehicle is braked by a brake device activated by a control device. The braking process is triggered, when an amplitude of the oscillation of the trailer exceeds a predetermined value. As a result, the tandem is decelerated to a speed at which the amplitude of the oscillation of the trailer falls below a predetermined value. The tandem is decelerated more intensely in the case of a wobbling trailer and when travelling at a first travelling speed than in the case of a wobbling trailer and when travelling at a second travelling speed which is lower than the first travelling speed, and the tandem is braked in presence of the first driving speed during exceeding a lower value of the amplitude than in the presence of the second driving speed.

The brake system has a main brake cylinder which can be actuated by a brake pedal, having at least one pressure chamber associated with at least one wheel brake, and a simulation device which co-operates with the main brake cylinder and gives the driver a brake pedal sensation in a brake-by-wire operating mode. When a predetermined operational state occurs in the brake-by-wire operating mode, a brake pedal reaction, as a change to the stiffness of the brake pedal sensed by the driver is carried out by means of a disengaging valve which is connected to the pressure chamber of the main brake cylinder and by which the action of the simulation device can be switched on and off.

Abstract: The invention relates to a method in which the driving stability of a vehicle is controlled, wherein a yaw rate difference is influenced by an additional yaw moment which is generated at least partially by building up braking torque independently of the driver at one or more wheels. According to the invention, the braking torque which influences the additional yaw moment is variably apportioned between the front axle and the rear axle of the vehicle in an oversteering situation.

Abstract: A process for increasing the stability of a vehicle upon acceleration on a roadway with a non-homogenous coefficient of friction, whereby a drive wheel is acted on by a braking force on a side with a low coefficient of friction by means of a drive slip regulation. A value (pASR) is determined which corresponds to the braking force (FB,ASR) set by the drive slip regulation (ASR). The value determined (pASR) is used for the determination of a disrupting yaw momentum (MZ), and a control portion (??Z) of a supplemental steering angle (??) is determined in dependence on the disrupting yaw momentum (MZ). An apparatus for the implementation of the process is also provided.

Abstract: Disclosed is a method of controlling the driving dynamics of a vehicle, in which a nominal value ({dot over (?)}ref) of a driving state variable that corresponds to a preset driver input is compared with a detected actual value ({dot over (?)}) of the driving state variable, and in which a rolling moment distribution is detected and modified. The method is implemented in such a manner that the driving performance of the vehicle is determined by comparing the nominal value ({dot over (?)}ref) of the driving state variable with the actual value ({dot over (?)}) of the driving state variable. Also, depending on the determined driving performance, a new rolling moment distribution is determined which corresponds to a predefined driving performance and the new rolling moment distribution is adjusted.
