An unlocking device for unlocking a lock of a movable vehicle element, in particular a vehicle door, a vehicle front hood and/or a vehicle tailgate is described. The device may have at least a detection unit for detecting at least one approaching object, and a lighting unit that may have an illumination region for illuminating a detection region of the detection unit. The lighting unit and/or the detection unit becoming or being activated at least when the locking mechanism is or has been brought into the pre-latching position.

Unlocking device for unlocking a lock of a movable vehicle element and vehicle

A capacitive sensor arrangement (), for sensing an approaching object (), is configured as a contact sensor () including a plurality of aligned, flat, spaced apart electrodes (to). One electrode () is a main electrode (S) and other electrodes are auxiliary electrodes (H). The evaluation unit () monitors the electrodes (to) together, such that changes in the capacitances of the plurality of auxiliary electrodes and changes in the capacitance of the main electrode are sensed and compared with one another and/or are compared with prescribed reference values. The evaluation unit () plausibility checks the sensed changes (D(S)) in the capacitance of the main electrode (S) on the basis of the sensed changes (D(H)) in the capacitances of the plurality of auxiliary electrodes (H) as to whether or not contacting of the main electrode or an approach towards the main electrode (S) has taken place.
