Abstract: A brake system may include an actuation device, in particular a brake pedal, a first piston-cylinder unit with two pistons, in particular an auxiliary piston and a second piston, in order to supply a pressure medium to brake circuits via a valve device. One of the pistons, in particular the auxiliary piston, can be actuated by means of the actuation device. The brake system may further include a second piston-cylinder unit with an electric motor-powered drive, a transmission, and at least one piston to supply a pressure medium to at least one of the brake circuits via a valve device and a motor-pump unit with a valve device to supply a pressure medium to the brake circuits. According to one aspect, a hydraulic travel simulator is connected to a pressure or working chamber of the first piston-cylinder unit.

Abstract: A diagnostic method, in particular to determine the leak tightness of at least one seal and/or one valve, for at least one component of a vehicle, wherein a piston cylinder unit, whose piston is driven by an electromotive drive, forms a pressure supply unit, wherein a control unit identifies the piston position and/or piston movement of the piston by means of at least one sensor and the pressure generated by the pressure supply unit or the motor current flowing through the drive by means of at least one sensor. During the diagnostic method, the control unit may be used to measure quantities relating to piston movement/position, pressure, and/or pressure variation.

Abstract: A diagnostic method may determine the leak-tightness of at least one seal and/or one valve function in a braking system with at least two brake circuits, following completion of a braking action. The diagnostic method may be carried out at a pressure still present after the braking action in one or both braking circuits and/or in hydraulic line or a working chamber of a piston-cylinder system or at a lower pressure, or it may be carried out at a pressure of at most 30 bar.
