Embodiment Construction

[0055] FIG. 1 shows the rear of a vehicle 1 . The sensor electrodes 2 are located in the area of ​​the rear bumper. Below the sensor electrode 2 there are other sensor electrodes 3 . The sensor electrodes 2 and 3 are each connected to a control and evaluation device 5 . The vehicle control unit 4 is arranged in any other position in the vehicle (see figure 2 ).

[0056] The electrodes are charged by a corresponding control / evaluation device 5 , the capacitance of the electrodes changes when an object (eg a body part of the user) approaches, and this change in capacitance can be detected by charge evaluation. Such capacitive sensor principles are known in the field of automotive technology.

[0057] In this embodiment, the sensor electrode arrangement 3 is substantially parallel to the electrode 2 .

[0058] A user standing behind the vehicle can, for example, swing his lower leg under the bumper when maneuvering. This movement and this approach are detected both by the ...

Abstract

The invention relates to a sensor device for detecting actuation gestures performed by a user of a motor vehicle to open the luggage compartment, for example. A first sensor is provided for detecting objects in a first three-dimensional zone, while at least one additional sensor is provided for detecting objects in another three-dimensional zone. The sensors have outputs for picking up time-related signal shapes, said outputs of the sensors being coupled to a processing unit. The processing unit implements a neural network to which the time-related signal shapes or patterns derived from the time-related signal shapes are fed. The processing unit includes a signal output which is coupled to the output units of the neural network and which can be queried in order to query an actuation signal. A signal is applied to said signal output in accordance with the result of the run through the neural network.

Description

technical field [0001] The present invention relates to a sensor device that can be operated by a user to operate a function of an automobile. In particular, the invention relates to a sensor device for detecting operating gestures made by a vehicle user for operating functions of the vehicle. Background technique [0002] Hyundai cars are equipped with sensor devices in a large number of locations, and their role is to identify user access to improve safety and ease of use. For example, many cars have sensor devices in the door handles in order to detect whether a user is approaching the door handle and to unlock the door after checking the access authorization. Using a sensor device in the area of ​​the vehicle's rear lid, the rear lid can be opened by means of contactless actuation. This is particularly advantageous if the user is unable to manually manipulate the rear cover, for example carrying a heavy object. In this case, the user can, for example, make gestures wi...
