1. A method for controlling movement of a vehicle closing element of a vehicle, the vehicle closing element configured to be moved into a closed position by an external force to close a body opening of the vehicle, wherein the vehicle closing element has a locking part for locking the vehicle closing element in the closed position, the method comprising:

  • detecting an obstacle in an adjustment path of the vehicle closing element moving to the closed position by using a capacitive anti-trap system;

    controlling the movement of the vehicle closing element using the capacitive anti-trap system such that an obstacle is prevented from being trapped between the vehicle closing element and a vehicle body defining body opening, anddetecting an obstacle in a monitoring region around the locking part using the capacitive anti-trap system in order to prevent a collision of the locking part with the obstacle at least as the vehicle closing element moves towards the closed position,wherein the vehicle closing element comprises two different closing edges on the vehicle body on which each vehicle closing element rests in the closed position and wherein the locking part is located on one of the closing edges; and

    wherein at least two electrode pairs of the capacitive anti-trap system each comprise a transmitter electrode and a receiver electrode which each extend over at least a part of the two different closing edges such that an obstacle at least at one of the closing edges and an imminent collision of the locking part with the obstacle can be detected due to an electric capacitance of the electrode pair changing on account of the obstacle.
