Claim:
1. A brake system for motor vehicles, comprising a brake pedal for operating a master brake cylinder with at least one hydraulic piston, at least one pressure chamber and at least one connected brake circuit that is placed under a brake system pressure of a pressure medium when the brake pedal is operated and the at least one connected brake circuit is connected to at least one hydraulically activated wheel brake that are associated with wheels of the motor vehicle, a displacement detection device, which detects an operating displacement of the brake pedal or of a component connected to the brake pedal, a pedal force detection device, which detects a force exerted on the brake pedal acting on the master brake cylinder, a brake pressure modulation unit that passes the brake system pressure to the wheel brakes or to regulate a brake pressure applied to the wheel brakes individually, an electrically controllable pressure supply device for supplying the pressure medium to the brake system, a cylinder-piston arrangement connected upstream of the master brake cylinder for the hydraulic generation of a force acting on the master cylinder piston in an operation direction in addition to the force exerted on the brake pedal, an electronic control and regulation unit, operated using a method for the regulation of the brake system pressure, at least one pressure sensor for detecting the brake system pressure, and the electronic control and regulation unit configured to activate the pressure supply device to produce a defined brake pedal state that has been determined by the electronic control and regulation unit wherein the state that is defined by the brake pedal travel and the brake pedal force is converted into a target state by a control method that minimizes a quality criterion related to a difference between the brake pedal travel and the brake pedal force and the target state.
