Title: METHOD FOR OPERATING A CONTROL DEVICE FOR A BRAKING SYSTEM OF A MOTOR VEHICLE, AND CONTROL DEVICE AND MOTOR VEHICLE,
Abstract:
The invention relates to a method for operating a control device (12) for a braking system (14) of a motor vehicle (10), wherein the control device (12) receives a braking request (16) from a driver assistance system (11) and determines a target value (21) of a braking operation parameter of the braking system (14) and determines an ideal temporal process (22) for the braking operation parameter, which gradually leads to the target value (21), complying with a predetermined jerk criterion (24), and a determines a control fault (29) of an actual value (25) of the braking operation parameter in relation to the ideal process (22) and determines a request value (18) for a controller (20) of a brake pressure pump (19) of the braking system (14) from the control fault (29) on the basis of a controller unit (PI). According to the invention, the control device (12) determines a maximum achievable temporal gradient (27) of the braking operation parameter by means of the brake pressure pump (19) and examines whether the gradient (27) fulfills a freezing criterion (33) and, in the case of the freezing criterion being fulfilled, limits at least one control operation parameter (31) of the controller unit (PI) and/or a gradient of the brake request (16).
