Abstract
A brake booster includes an input element actuatable by a driver, an actuator for generating a support force, an output element to which an input or support force may be applied and via which an actuating force may be applied to a piston of a brake master cylinder, and a force transmission unit having elastic properties, situated between the input element and the actuator, and the output element, and transmitting the input and/or support forces to the output element. An air gap, which in idle mode is smaller or larger than a desired air gap, is provided between the input element and the force transmission unit. A method for operating the brake booster includes generating a support force prior to a braking intent to be anticipated or immediately after detection of a braking intent, in a time span before or immediately after detection of an actuation of the input element.
