A method for detecting a change in a transmission channel system of a vehicle. The method includes: transmitting a broadband transmission signal; receiving a signal; determining in-phase data and quadrature-phase data of a channel pulse response of the transmission channel system; determining a respective actual phase angle of the plurality of channel pulse responses at a characteristic location; determining a respective phase rotation angle of the plurality of channel pulse responses; rotating the plurality of channel pulse responses in a limited viewing area of a delay time direction; and detecting the change in the transmission channel system based on a change in the in-phase data and/or the quadrature-phase data.

An assistance method for a light control system in a motor vehicle, having a light controller for controlling a lighting unit in the motor vehicle for lighting a motor vehicle environment, a portable unit, at least one communication interface, and an evaluation unit for evaluating signals from the portable unit received via the communication interface. The lighting unit being controllable by the light controller and in accordance with the evaluation of the signals received from the portable unit in a first assistance function, such that at least one light beam emitted by the lighting unit can be positioned as a function of the position of the portable unit. The lighting unit is controlled via the light controller, such that when the first assistance function is switched on, the light beam emitted by the lighting unit automatically tracks the portable unit in accordance with the motion trajectory of the portable unit.

An authorization system for vehicles, comprising at least one authentication element, at least one device for the location of the authentication element, and at least one compare unit. The authentication element, comprises: at least one wireless interface for the sending and/or receiving of at least one location data signal generated on the vehicle; at least one inertial sensor element for the detection of inertial data; at least one inertial data interface for the sending and/or receiving of inertial data; and at least one location data signal exchange interface for the exchange of location data signals with the compare unit. The compare unit comprises at least one reception device for the reception of the location signal data and the inertial data, and at least one processing unit for the generation of compare data based on the location signal data and the inertial data.

Access and drive authorization system with increased safety against relay station attacks by verification of location

A method for wirelessly accessing a vehicle including the steps of: exchanging data between a UID-transponder and the vehicle to verify authorization of the UID-transponder, triangulating a location of UID-transponder relative to the vehicle using at least three first antennas being positioned at three different first positions of the vehicle and providing access to the vehicle under the first authorization condition that the UID-transponder is identified as an authorized UID-transponder and if the location meets a second authorization condition as well, to recognize a relay attack.

Vehicle theft protection system

A method for remote controlling an object with a remote-control unit is provided. At least a first surface S, S, Sis defined in a first coordinate system. At least a first function of the object is associated to the first surface S, S, S. A second coordinate system is defined at the position of the remote-control unit. A static pointing vectoris defined in the second coordinate system. It is then determined whether the pointing vector points towards the first surface S, S, S. If so, the object is enabled to selectively activate the first operation upon receipt of an activation command.

Remote control for automotive applications

An authentication element that may include a keyless go device for a vehicle. The authentication element may include a transponding interface for transmitting an authentication signal and receiving power and data. A sensor element may also be provided for detecting a movement and/or inclination. The authentication element is designed such that authentication signals are transmitted over the transponding interface when the sensor element detects a stored movement and/or inclination. An authentication system for vehicles may include at least one authentication element and an apparatus.

Access and driving authentication system with increased security against relay attacks on the transponding interface

An apparatus for a vehicle key, an apparatus for a vehicle control system, and an apparatus for a mobile device. The apparatus includes a first interface to communicate with a vehicle control system and a second interface to communicate via a radio connection. The apparatus also includes a control module to receive proximity information from the vehicle control system via the first interface and to establish a radio connection via the second interface if the proximity information indicates spatial proximity of the vehicle key to the vehicle control system.

Apparatuses, methods, and computer programs for establishing a radio connection on the basis of proximity information

An authentication element, specifically a keyless go device for a vehicle. The authentication element has a transponding interface for transmitting an authentication signal and receiving power and data. The authentication element also has a key button device for detecting user input, whereby the authentication element is designed such that authentication signals are transmitted over the transponding interface if the key button device detects user input. An authentication system for vehicles includes at least one authentication element and an apparatus.

Access and driving authorization system with increased security against relay attacks on the transponding interface

An arrangement on monitoring of authentication, in particular for motor vehicles, includes a first communication apparatus and at least a second communication apparatus, between which a wireless communication channel can be set up. The communication apparatus items have means for authentication and encryption, with which the exchangeable data may be encrypted via the communication channel. The items of communication apparatus have storage means in which one of the digital keys usable for authentication and encryption can be stored, and in that in the storage device there is either in addition to the digital key and/or in the individual key at least one piece of information regarding at least one past communication between the first communication apparatus and the second apparatus that can be stored in memory.

Apparatus and method for authentication for motor vehicles

In a method and a device () for actuating a door or flap () of a vehicle (), the door or flap (), if it is closed, is automatically opened or, if it is open, is automatically closed if a movement of an object with at least one change in direction is detected outside the vehicle () and at the same time a key () assigned to the vehicle () is detected.
