Abstract:
1. A method for operating a brake system for motor vehicles, comprising: a master brake cylinder which can be actuated by a brake pedal and which is separably connected to at least one brake circuit (I, II) with at least one hydraulically actuable wheel brake, wherein a first variable (P a hydraulically actuable pedal travel simulator which is or can be connected to the master brake cylinder and which is designed so as to be capable of being switched on and off by a simulator release valve, an electrically controllable pressure supply device which is separably connected to the brake circuit (I, II) and which is formed by a cylinder-piston arrangement whose piston can be actuated by an electromechanical actuator, and an electronic open-loop and closed-loop control unit for activating the electrically controllable pressure supply device and valves of the brake system, wherein, when the brake pedal is actuated, in a first operating mode (Z wherein in a case of a changeover from the second operating mode (Z wherein a first characteristic curve, which describes a relationship between the first and second variables (P
