The invention relates to a device for use in an electronic driving dynamics control system, comprising an electromechanical converter, especially an electromotor, a hydraulic pump (17), and an electric control device (4, 5, 16) for the converter. Said converter comprises a magnetic or magnetizable stator (10) and a rotor (11), as well as connections (6 9) for connecting the control unit, and a commutation device (2, 12 15) for controlling the electromagnetic windings of the rotor. The inventive device is further characterized in that the commutation device comprises three or more commutation elements (12 15) that are electrically connected to the respective connections so that the windings of the rotor can be individually controlled by the control unit (4, 5, 16). At least one commutation element is connected to a switching element (5) that provides an additional connection (21) for connecting a rotational speed measurement device (4).

The invention relates to an electrohydraulic brake system for motor vehicles that can be controlled in a brake-by-wire mode both from the driver as well as independently of the driver. The brake system is preferably operated in the brake-by-wire mode and can also be operated in a fallback mode in which it can only be operated by the driver. The aim of the invention is to increase the operating reliability of the brake system and/or to provide a brake system which is capable of supplying sufficient hydraulic volume in all driving situations. To this end, the system has means (5,16,16',17,17',40;5,30,29,33,34;47;52,53,54,55,110) for providing a hydraulic volume flow that ensures in the fallback mode at least the hydraulic volume required for the respective delay.

The invention relates to a device for supplying pressure to an actuation device for a motor vehicle braking system, in particular for a Brake-by-wire type motor vehicle braking system. Said device comprises a pneumatic motor-pump-unit (3) comprising a pump (6) and a motor (7) which drives the pump (6). The motor-pump unit (3) is controlled by an electronic control unit (10, 12) according to a pressure level and/or pressure difference in a pneumatic brake booster (1) of the actuation unit. The pressure level in a chamber and/or pressure difference between two chambers of the brake booster (1) is detected by means of a sensor (9). According to the invention, the control unit (10, 12), which is used to control the motor-pump unit (3), comprises a logic module and a power module which are separated from each other in order to maintain the availability of the operational brake function as high as possible and also to obtain a possible high redundancy, in particular in relation to errors or failure of the electronic system or of the border network.
