Abstract

The invention relates to a method for operating a braking system of a motor vehicle, and to a braking system, the braking system having an electrically controlled pressure supply device (5), which consists of at least one hydraulic pressure chamber (37). ) cylinder-piston assembly, the piston (36) of the cylinder-piston assembly can be moved by an electromechanical actuator (35); a plurality of wheel brakes (8, 9, 10, 11), respectively, through an electrically operated inlet valve (6a-6b) are connected to the pressure supply device (5); and at least one of the wheel brakes has an electrically operated discharge valve (7a-7d) by means of which the wheel brake can be connected to a pressure medium storage container ( 4) Connect. In the normal regulation mode (N) of the braking system, when a predetermined braking condition (A) exists, the piston (36 of the pressure supply device (5) is terminated by outputting a control signal to the pressure supply device ) and close the inlet valve of the wheel brake. When the predetermined conditions (B) for the pressure supply device are present, a transition to the special regulation mode (S) occurs. In the special regulation mode, the movement of the piston (36) of the pressure supply device (5) is terminated by outputting a control signal to the pressure supply device when a predetermined braking condition (A) exists, and for at least one selected The outgoing wheel brakes (8, 9) keep the corresponding inlet valves (6a, 6b) open and open the corresponding outlet valves (7a, 7b) at least temporarily, while the inlet valves ( 6c, 6d) closed.

Description

technical field [0001] The invention relates to a method for operating a brake system and a brake system for carrying out the method. Background technique [0002] From DE 10 2010 040 097 A1 a "brake-by-wire" braking system for motor vehicles is known, which comprises a tandem brake master cylinder operated by a brake pedal, a brake Simulator of the hydraulic connection of the active master cylinder, an electrically controlled pressure supply device and a pressure modulation device for adjusting the wheel-dependent brake pressure, said pressure supply device consists of a cylinder-piston assembly with a hydraulic pressure chamber, the The piston of the cylinder-piston assembly is displaceable by an electromechanical actuator, and the pressure modulation device has an inlet valve and an outlet valve for each wheel brake. In order to perform normal braking in the "brake-by-wire" operating mode of the brake system, the wheel brakes are charged with a pressure supply by means o...
