A hydraulic braking system has a vacuum brake booster, an ESC system with a hydraulic pump for generating braking force in a wheel-specific manner in a plurality of wheel brakes, an ESC control device for driving the hydraulic pump and a hydraulic pressure sensor for determining a hydraulic pressure in the hydraulic braking system. For electrified vehicles, an electric vacuum pump is provided for supplying the vacuum brake booster, wherein the ESC control device is designed to drive the electric vacuum pump logically and electrically.

Vacuum-boosted braking system having redundancy

The present invention relates to a device in an electronic driving dynamics control system, comprising an electromechanic transducer, especially an electric motor, a hydraulic pump, and an electric actuating unit for the transducer, said transducer including a magnetic or magnetizable stator and a rotor, as well as connections for connecting the actuating unit, and a commutation device for the actuation of electromagnetic windings of the rotor, said invention inhering the special feature that the commutation device comprises three or more commutating elements that are electrically connected to the respective connections so that the windings of the rotor can be actuated individually by the actuating unit, with at least one commutating element being connected to a change-over element that provides for an additional connection for connecting a rotational speed measurement devices.

Electrohydraulic converter

The present invention relates to a method and apparatus for reducing voltage sags in the battery supply lines of the circuit arrangement which is used to regulate or control the current input of a consumer in an automotive vehicle, wherein the consumer current is regulated or controlled by pulse-width modulation (PWM) and a controllable switch is used. To this end, a circuit is used which influences the edges of a pulse-width modulated signal, and a signal representative of the rate of change in the current in the battery supply lines to the consumer is produced. This signal is fed back to the input signal by way of a capacitor.
