Abstract
A device for determining the saturation point of a vacuum brake booster having a vacuum chamber and a working chamber that are separated from one another by a membrane. The reaching of the saturation point can be recognized simply and precisely if the vacuum prevailing in the vacuum chamber is measured using a pressure sensor, and the output signal of the pressure sensor is evaluated by an electronic evaluation system that calculates the saturation point using a mathematical function, taking into account only the pressure prevailing in the vacuum chamber.
