Abstract

The present invention relates to a combined capacitive sensor and heating apparatus (10, 60, 70) having a capacitive sensor device for detecting the presence of a capacitively effective actuation means in a detection region of the sensor device, and having a heating device, wherein the sensor and heating apparatus (10, 60, 70) has an electrical combined sensor and heating element (4), wherein a synchronization device (40) is configured to capture an actual voltage applied to the first electrical path (P1) between the first pole (V+) of a voltage source and the first connection (5) of the combined sensor and heating element (4) and/or an actual current flow and/or to capture an actual voltage applied between the second connection (6) of the combined sensor and heating element (4) and the second pole (GND) and/or an actual current flow and to detect an instantaneous actual state of the heating device on the basis thereof, and to control the sensor device and/or output at least one control signal for at least partially controlling the sensor device on the basis of the detected actual state of the heating device.
