Claim:
1. A method for operating a brake booster of a vehicle, the method comprising: determining an actual displacement speed signal representing a measured actual displacement speed of an input rod, to which a driver brake force exerted on a brake actuating element is at least partially transmitted; filtering out from the actual displacement speed signal at least one of: high-frequency signal components, or low-frequency signal components; determining a setpoint displacement speed signal representing a setpoint displacement speed of at least one booster piston, which is displaceable with the aid of the brake booster, as a function of a predefined characteristic curve and the filtered actual displacement speed signal; determining an activation signal for the brake booster as a function of the setpoint displacement speed signal; and providing the activation signal to the brake booster to activate the brake booster to displace the at least one booster piston at an execution speed corresponding to the activation signal.
