Arrangement for an electrohydraulic brake system and method for controlling electrohydraulic brake system and tandem master brake cylinder

摘要

A method and an arrangement are provided for the return of brake fluid from a pedal travel simulator into the auxiliary brake circuit of an electrohydraulic brake system, and to an electrohydraulic brake system and a tandem master brake cylinder. For this purpose, in an emergency, the return line of the pedal travel simulator, which is connected to the brake fluid reservoir during normal operation, is separated from the unpressurized brake fluid reservoir and instead connected to the delivery side of the electrohydraulic pressure supply system or at least to the pressure accumulator of the electrohydraulic system.
