Patent ID: 8886430

Claim:
A method for operating a brake-boosted brake system of a vehicle, the method comprising: determining, by a controller, braking force information ( 28 ) with respect to a driver braking force (Ff) applied to an actuating element ( 10 ) by a driver of the vehicle and which is at least partially transferred to an input piston ( 12 ) of the brake system (S 1 ); characterized by: determining, by a controller, an actual speed parameter ( 34 ) with respect to an adjustment speed (v 2 ) of a servo piston ( 16 ) of the brake system to which a servo power (Fu) of a brake booster ( 14 ) of the brake system is applied (S 2 ); determining, by a controller, a relative speed parameter ( 40 ) with respect to a relative speed (vd) of the servo piston ( 16 ) relative to the input piston ( 12 ) (S 3 ); establishing, by a controller, a target speed parameter ( 50 ) with respect to the adjustment speed (v 2 ) of the servo piston ( 16 ) based on the determined braking force information ( 28 ), the determined actual speed parameter ( 34 ) and the determined relative speed parameter ( 40 ) (S 4 ); and actuating the brake booster ( 14 ) based on the established target speed parameter ( 50 ) (S 5 ).
