Control device and method for operating a braking system equipped with an electrical drive device and/or generator device

The invention relates to a control device (10) for a braking system equipped with an electrical drive device and/or a generator device (58) and having a first receiver by means of which a predetermined parameter (14) with respect to a brake pressure can be received in at least one wheel brake cylinder (54a, 54b) of at least one brake circuit (50, 52), a second receiver by means of which an actual value (18) with respect to a pressure can be received in the at least one brake circuit (50, 52) and/or the brake pressure can be received in the at least one wheel brake cylinder (54a, 54b), and a control device by means of which a target mode of the electrical drive device and/or generator device (58) can be determined on the basis of the received predetermined parameter (14) and the received actual value (18), and a corresponding control signal (26); can be output to the electrical drive device and/or generator device (58) so that the electrical drive and/or generator device (58) can be controlled by means of the
