Abstract:
1. A method for controlling a brake which can be actuated electrically by an actuator ( 2 ), comprising the steps of, determining an actuator clamping force actual value (F ist ) by providing a clamping force sensor ( 7 ), determining an actuator position actual value (φist) or an actuator speed actual value (n ist ) by providing a position sensor ( 8 ), generating a manipulated variable (U) for activating the actuator ( 2 ) by providing a controller device ( 1 ), the controller device ( 1 ) having a selection and evaluation device ( 3 ) and a controller structure ( 4 ), the selection and evaluation device ( 3 ) supplying to the controller structure ( 4 ) a controller structure input reference value (φ in-soll and a controller structure input actual value (φ in-ist ) as controller structure input variables, and the controller structure input variables (φ in-sol , φ in-ist ) being made available by the selection and evaluation device ( 3 ) wherein the controller device ( 1 ) operates using the same controller structure ( 4 ) in at least two control modes including a force control mode (M 1 ) for adjusting an actuator clamping force reference value (F soll ), and a position control mode (M 3 , M 4 ) for adjusting an actuator position reference value (φ soll , Δφ soll ), and a speed control mode (M 2 ) for adjusting an actuator speed reference value (n soll ).
