Abstract
A brake booster includes an input element actuatable by a driver, an actuator for generating a support force, an output element that receives at least one of an input or support force and that applies an actuating force to a piston of a brake master cylinder, a force transmission unit having elastic properties and transmitting the input and/or support forces to the output element, and a preload unit acting on the force transmission unit to apply a force couple to the force transmission unit when the brake booster is in idle mode. 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.
