Claim 6:
7. A sensor device for an electromechanical brake booster of an on-board hydraulic braking system, comprising:
a processing unit, which is configured to calculate, 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, to calculate, for an input element displaced out of its input element starting position using the driver braking force and the coupling element of the electromechanical brake booster, which is provided downstream from the support element displaced out of its support element starting position with the aid of the motor force and also displaced out of its coupling element starting position at least with the aid of the motor force, whether an open 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
a memory unit on which at least one first formula and one second formula deviating from the first formula are stored, each for establishing at least one actual variable with respect to a coupling element path of the coupling element out of its coupling element starting position and/or a coupling element velocity of the coupling element;
wherein the processing unit is configured, in the case of an open intermediate gap, to establish at least one actual variable using the first formula provided by memory unit and, in the case of a closed intermediate gap, to establish the at least one actual variable using the second formula provided by memory unit.
