Claim 0:
1. A detection method for an electromechanical brake booster of an on-board hydraulic braking system, comprising the following steps:
ascertaining, while both a driver braking force, which is exerted on a brake actuating element, is transferred to a connected input element of the electromechanical brake booster and a motor force of an electric motor is transferred to a connected support element of the electromechanical brake booster in such a way that the input element is displaced out of its input element starting position using the driver braking force and the support element is displaced out of its support element starting position using the motor force, and a coupling element of the electromechanical brake booster which is provided downstream from the input element and the support element is also displaced out of its coupling element starting position at least using the motor force, whether an intermediate gap, which is open when the input element is present in the input element starting position and the coupling element is present in the coupling element starting position, is closed in such a way that the coupling element is also displaced using the motor force and using the driver braking force; and
establishing at least one actual variable with respect to a coupling element path of the coupling element out of the coupling element starting position and/or a coupling element velocity of the coupling element, wherein in the case of an open intermediate gap the at least one actual variable being established using a first formula, and in the case of a closed intermediate gap the at least one actual variable being established using a second formula deviating from the first formula.
