Abstract

A system and method for operating a brake system for motor vehicles, includes a master brake cylinder actuated by a brake pedal and separably connected to at least one hydraulically acutuatable wheel brake by at least one brake circuit, a hydraulically operable pedal travel simulator is connectable to the master brake cylinder, an electrically controllable pressure provision apparatus is separably connected to the brake circuit, and an electronic open-loop and closed-loop control unit. Upon brake pedal actuation, a pressure of the pressure provision apparatus is applied to the brake circuit in a first operating mode and the pressure of the master brake cylinder is applied to the brake circuit in a second operating mode. In the event of transition from the second operating mode to the first operating mode while the brake pedal is actuated, the actuation travel of the brake pedal is adjusted by electronic open-loop or closed-loop control.
