Abstract
In a device and a method to produce a user recognition signal upon an actuation by a user in a vehicle using a control unit linked with a transmitter and receiver which are disposed relative to one another to set up a user-specific high frequency transmission path therebetween upon actuation by the the user, at least one HF signal is provided and transferred through the body of the user, the HF transfer is evaluated to determine the user-specific transmission path to identify the user, and a user recognition signal is produced that identifies the user, wherein using at least one detection unit an action of the user is detected or an action presence is monitored, and in the detection of the action an action signal is produced, and the transmitter only provides the one HF transmission signal after or upon the existence of an action signal.
