Control unit, in particular for a vehicle component

摘要

The control unit, in particular for a vehicle component, is provided with a manually actuable control element (12) for selecting and optionally for activating a control function, wherein the control element (12) can be moved manually into a selection and/or trigger position for selecting and optionally for activating a control function. In addition, the control unit has a capacitive tactile sensor (41) for identifying manual touching contact with the control element (12) and optionally identifying the event of a hand approaching the control element (12), wherein the tactile sensor (41) has a first and a second electrode (38, 40), which have electrode sides which substantially face one another and are spaced apart from one another. The first electrode (38) is arranged on the control element (12). The second electrode (40) is arranged immovably. The two electrodes (38, 40) extend with respect to one of the two dimensions thereof spanning the electrode sides parallel to the direction of the relative movement of the two electrodes (38, 40), said relative movement being performed as the control element (12) is moved manually into the selection and/or trigger position, wherein the size of the overlapping areas (34, 36) of the opposing electrode sides, which overlapping areas are provided during the relative movement of the two electrodes (38, 40), remains substantially the same.

1. A control unit, comprising
a manually actuable control element for selecting and optionally for activating a control function, wherein the control element can be moved manually from a non-selection and/or non-trigger position into a selection and/or trigger position for selecting and optionally for activating a control function, and a capacitive tactile sensor for detecting manual touching contact with the control element and optionally for detecting the event of a hand approaching the control element, wherein the tactile sensor has a first and a second electrode, which have electrode sides which substantially face one another and are spaced apart from one another,wherein
the first electrode is arranged on the control element, the second electrode is arranged immovably, and the two electrodes extend with respect to one of two dimensions thereof spanning the electrode sides parallel to the direction of movement of the first electrode relative to the second electrode, said movement being performed as the control element is moved manually into the selection and/or trigger position, wherein a size of overlapping areas of opposing electrode sides, existing during the movement of the first electrode relative to the second electrode between the non-selection and/or non-trigger position to the selection and/or trigger position, remains substantially the same.
