ANTI-PINCH SENSOR
First Claim
1. Anti-pinch sensor for detecting an obstacle in a path of an actuating element of a motor vehicle, the anti-pinch sensor comprising:
- a sensor body with an electrically isolated measuring electrode that is provided in the sensor body and to which a measuring potential can be applied;
a calibrating electrode, which is provided in the sensor body adjacent to the measuring electrode and to which a calibrating potential can be applied; and
a control unit, which is configured to control the measuring electrode and the calibrating electrode so that the measuring potential and the calibrating potential are substantially equal in a measurement phase and differ from one another in a calibration phase.

Abstract
An anti-pinch sensor, particularly for detecting an obstacle in the path of an actuating element of a motor vehicle is provided, having a sensor body, a measuring electrode, which is disposed in the sensor body and to which a measuring potential can be applied, a calibrating electrode, which is electrically disconnected and disposed in the sensor body adjacent to the measuring electrode, and a control unit. The control unit controls the measuring electrode and the calibrating electrode such that the measuring potential and the calibrating potential are equal in a measuring phase, and differ from each other in a calibrating phase.
