Abstract

A sensor arrangement for detecting a pedal movement in a vehicle includes a measurement value transmitter that is arranged on a piston that is translated by the pedal movement and a measurement value sensor that is arranged in a stationary manner in the movement region of the piston. The measurement value sensor in connection with the measurement value transmitter generates a signal that represents the pedal movement. The measurement value transmitter and the measurement value sensor are configured as inductive sensors. The measurement value transmitter has at least one detection region, and the measurement value sensor has at least one detection coil. The at least one detection region of the measurement value transmitter influences the inductance of the at least one detection coil such that the changing inductance of the at least one detection coil of the measurement value sensor is interpreted as a measure of the pedal movement.
