Abstract: A brake pedal unit includes a housing defining a bore formed therein. An input piston is slidably disposed in the bore. The input piston is connected to a brake pedal such that engagement of the brake pedal causes movement of the input piston within the bore of the housing of the brake pedal unit. The brake pedal unit is defined to be in an at rest position when the brake pedal in not engaged causing movement of the input piston. A primary piston is slidably disposed in the bore for pressurizing a primary chamber. A primary passageway permits fluid communication between the primary chamber and the reservoir, wherein fluid flow through the primary passageway is blocked when the brake pedal unit is in the rest position. A secondary piston is slidably disposed in the bore for pressurizing a secondary chamber. A secondary passageway permits fluid communication between the secondary chamber and the reservoir, wherein fluid flow through the secondary passageway is blocked when the brake pedal unit is in the rest position.

Abstract: An object of the present invention is to provide a brake apparatus that allows low-cost attachment of a stroke sensor that detects a stroke amount of a brake pedal. The brake apparatus is configured in such a manner that the stroke sensor that detects an amount of an axial stroke of a piston is disposed between one side surface of a master cylinder housing and one side surface of a valve housing, and an output of the stroke sensor is transmitted via a through-hole formed on the valve housing when being transmitted to a control unit attached to an opposite side surface-side of the valve housing.

Abstract: A method and system for operating a brake system for motor vehicles, including a plurality of wheel brakes for which wheel-individual nominal pressure includes an electrically controllable pressure supply device, to provide a brake system pressure for actuating the wheel brakes. The brake system pressure provided by the pressure supply device can be determined. An electrically controllable inlet valve and electrically controllable outlet valve per wheel brake adjust wheel-individual brake pressures. At least one outlet valve is analogized for analog-controlled and is controlled by an electric control variable, wherein at least one valve-specific control characteristic and/or a valve-specific parameter is determined for the analogized or analog-controlled outlet valve by the brake system, and wherein the analogized or analog-controlled outlet valve is controlled as a function of the valve-specific control characteristic and/or the valve-specific parameter for the degradation of the brake pressure in the wheel brake associated with the outlet valve.
