摘要： An electromechanical brake system, particularly for motor vehicles, with a pedal simulator and brake modules is disclosed. A central module is also provided. The connection between the aforesaid modules can be provided by a data bus. The central module evaluates the braking request signals from a sensor device and checks them for errors. Also, a central module supplies and appropriate desired braking value based on the braking request and possibly higher functions such as ABS or ASR. The desired braking value is then conveyed on to the brake module, which then determines the corresponding control signals for the actuators, which interact with the wheels in order to brake the vehicle as the driver requires.

摘要： This invention relates to an electromechanical brake system, in particular for automotive vehicles, which includes a pedal module and at least two brake modules. Further, a central module may be provided. Connection between the aforementioned modules can be made by a data bus. The data bus is provided redundantly. In one embodiment, the central module can evaluate signals of a sensor system and examine them for their errors. Further, the central module can emit a corresponding nominal braking value which then is emitted to the brake modules. Thereupon, the brake modules determine appropriate actuating signals for the actuators which interact with the wheels in order to realize the driver's braking intention.

摘要： The present invention relates to an electrically operable brake system and a method for its actuation. The brake system and the method are characterized in that the service brake system can be activated by two brake operating devices which are operable by the driver independently of each other. The main advantage which results is that upon failure of a brake operating device which is e.g. configured as a brake pedal module, braking of the vehicle can be achieved by means of the service brake system by way of the second brake operating device. The additional functions intended for the service brake system, such as ABS, TCS, driving dynamics control, brake assist system, etc., may then be implemented, if so desired. The redundant design of the actuation for the service brake permits achieving a high degree of operational safety because full braking functions can be maintained even in case of emergency braking.

摘要： A method for operating a vehicle braking system for motor vehicles including a hybrid or electric drive and hydraulically actutable wheel brakes on the front axle, wherein the wheels associated with the rear axle are driven at least partially by an electric motor that can be operated as a generator to recover braking energy and, in generator mode, exerts a braking force on the vehicle wheel associated with the respective axle, thereby generating a drag torque including the braking torque and the regeneration torque of the electric drive, the drag torque being separately regulatable on the front and rear axles. To prevent overbraking of the rear axle and a loss of driving stability of the vehicle, a regeneration torque acting on the rear axle is controlled or regulated such that the drag torque acting on the rear axle does not exceed a maximum drag torque value associated with that axle.
