摘要:
The invention relates to an activation device (1) comprising a cover element (2), a light distribution device (7) arranged under the cover element (2), and a light source (9c) arranged under or in the light distribution device. The light source and the light distribution device backlight the cover element. The cover element has an operating region (5) oriented outward and formed partially of electrically-conductive metallic material. This operating region is electrically decoupled from the other components so that no conducting connection exists. A printed circuit board (8) with a capacitive sensor (9b) is arranged in turn under the light distribution device (7) so that the capacitive sensor is capacitively coupled to the metallic operating region (5) and the operating region serves as a sensitive access point of the capacitive sensor. A control and evaluation circuit (9d) is coupled to the light source (9c) and also to the proximity sensor (9b) in order to switch the light source depending on a proximity.

The invention relates to a method for operating a passive access system for a vehicle (1). A vehicle transmission device (3a, 3b, 3c) for transmitting wireless low-frequency electromagnetic signals and a vehicle transceiver device (2) for wireless high-frequency electromagnetic signals are arranged on the vehicle, and a mobile vehicle key (8a, 8b) with a key receiving device for wireless low-frequency electromagnetic signals and a key transceiver device for wireless high-frequency electromagnetic signals are provided. The vehicle is equipped with a sensor device (5) for detecting a user approaching a vehicle door, said device being set to a passive non-sensing state. The surroundings of the vehicle (1) are scanned by transmitting low-frequency wake-up signals (4a, 4b, 4c). If the wake-up signals are received in the mobile vehicle key (8b) and a dialogue is initiated between the vehicle key and the vehicle in response thereto, the sensor device (5) on the vehicle is set to an active operating state.

The invention relates to an assembly (1) for actuating a vehicle function, having a cover element (2), which is at least partially formed as a vehicle emblem. A light distribution device (7), which is arranged under the cover element (2) and has a light source (9c) arranged under or in the light distribution device, is arranged to backlight the cover element. A printed circuit board (8) having a proximity sensor (9b) is arranged under the light distribution device (7), the proximity sensor being formed and aligned to sense proximities to the cover element (2). A control and evaluation circuit (9d) is coupled to the light source (9c) and to the proximity sensor (9b) in order to switch the light source depending on a proximity.
摘要:
The invention relates to a sensor arrangement for the capacitive sensing of approximations close to a motor vehicle (1), comprising a capacitive sensor electrode (2, 3; 25) and at least one control and evaluation device (4) which is coupled to the sensor electrode and which senses a change in the capacitance of the sensor electrode. Said sensor electrode (2, 3; 25) is an elongate flat electrode, wherein in the longitudinal direction of the sensitive electrode, first electrode sections (a) having a first surface width and a first deformability alternate with second sections (b) having a second, narrower surface width and a second deformability such that electrode surfaces, which have different levels of deformability, have different measurements and which are continuously conductive and joined, are formed. A deformable and electrically insulating sheathing (30; 40) surrounds the sensor electrode.
