Electrohydraulic motor vehicle brake system and method for operating the same

A computer program product with a program code for performing a method for operating an electrohydraulic motor-vehicle brake system which has a master cylinder, an electromechanical actuator for generating a hydraulic pressure at a plurality of wheel brakes, and a set of electrically actuable valve arrangements, the set of valve arrangements each comprising a first valve arrangement between the master cylinder and each wheel brake in order to generate the respective braking pressure intended for each of the wheel brakes by means of the electromechanical actuator, comprising the steps:

• generating a regenerative current by operating an electric motor of the
• electromechanical actuator as a generator;
• and
• energising at least one electrical load with the regenerative current, wherein the at least one electrical load comprises at least one valve arrangement from the set of valve arrangements when the computer program product runs on at least one processor.

An electrohydraulic motor-vehicle brake system comprising:

• a master cylinder;
• an electromechanical actuator for generating a hydraulic pressure at a plurality of wheel brakes;
• and
• a set of electrically actuable valve arrangements each with a first valve arrangement between the master cylinder and each wheel brake in order to generate the respective braking pressure intended for each of the wheel brakes by the electromechanical actuator;
• and
• a control device or control device system which is designed for
• generating a regenerative current by operating an electric motor of the electromechanical actuator as a generator;
• and
• energising at least one electrical load with the regenerative current, wherein the at least one electrical load comprises at least one valve arrangement from the set of valve arrangements.
