METHODS FOR CONTROLLING A CAPACITIVE ANTI-TRAP SYSTEM AND ANTI-TRAP SYSTEM

The present invention relates to methods for controlling a capacitive anti-trap system of a vehicle. At least two transmission electrodes and one reception electrode of the capacitive anti-trap system are used for detecting an obstacle, and an electrical field is generated by a pair comprising transmission electrode and reception electrode by actuation of the respective transmission electrode by alternating electric current, said electrical field being influenced by an obstacle such that an electrical capacitance is measurably changed. A changing electrical capacitance is determinable on the basis of a signal received via the reception electrode and this signal is evaluated by means of an electronic evaluation unit at least during closing of the vehicle closing element in order to determine the presence of an obstacle in the displacement path of the vehicle closing element.
