Abstract: Vehicle hands-free liftgate systems of vehicles. Responsive to an object movement at the rear of the vehicle during a first vehicle mode, proximity signals generated by proximity sensors of the vehicle responsive to the object movement are associated with an actuation case, and responsive to another object movement at the rear of the vehicle during a second vehicle mode, proximity signals generated by the proximity sensors responsive to the another object movement are associated with a non-actuation case. A classifier is generated based on application of the proximity signals and associations to a machine learning algorithm. Responsive to a further object movement associated with the actuation case at the rear of the vehicle during a third vehicle mode, a determination is made that the further object movement is associated with the actuation case based on the classifier. Responsive to the determination, the liftgate is actuated.

Abstract: The invention relates to a control system for driving a motorized closure element of a motor vehicle, wherein a control arrangement and at least one distance sensor are provided in order to detect operator control events, wherein a distance from a user can be detected by means of the distance sensor. The invention proposes that the distance sensor has a changing sensitivity along a sensor extent, and in that a longitudinal movement by the user along the sensor extent produces a pattern in the profile of the sensor signal with respect to time, which pattern is detected by the control arrangement at least as part of an operator control event, owing to the sensitivity profile along the sensor extent.
