A device for operating an access and/or driving authorization system of a vehicle includes a mobile access and/or driving authorization unit, a control unit arranged in the vehicle, and at least one detection unit which can be coupled to at least one electronic communication unit. The at least one electronic communication unit is arranged integrated into a document. The at least one detection unit is arranged integrated in the mobile access and/or driving authorization unit and/or in the vehicle. A presence checking operation of the document can be carried out automatically by the at least one detection unit for a person who is in possession of the mobile access and/or driving authorization unit at a specific time. An output unit outputs a message to the person at the specific time as a function of a result of the presence checking operation.

Device and method for operating a vehicle access and/or driving authorization system

A driver authorization system for a vehicle includes an on-board identification device for communicating with a mobile release device to verify usage authorization, an ignition lock, ignition key, and a control unit for activating ignition lock functions (such as starting and switching off the engine) when the ignition key is brought into a corresponding position in the ignition lock. The ignition lock functions can be activated by means of the control unit using a pushbutton (), that can be mounted in, actuated while mounted, and removed from the ignition lock.

Driver authorization system

The invention relates to an actuating device for an automatic transmission of a motor vehicle. To allow the motor vehicle to be operated safely and managed conveniently, the invention makes provision for the actuating device to have not only a first device, by which a parking interlock can be engaged and released in normal operation of the actuating device, but also a second device, by which the parking interlock can be engaged in the event of a malfunction.

Actuating device for an automatic transmission of a motor vehicle

Component replacement warning system for a transportation mechanism, which monitors the unauthorized removal or installation of a component ( ) of the transportation mechanism, wherein the component replacement warning system ( ) include a first communication device ( ) that is firmly connected to the transportation mechanism, a second communication device ( ) that is connected to the component ( ), and an electronic authorization verification device that checks whether a component ( ), which is connected to the second communication device ( ) is installed in the transportation mechanism provided therefor in an authorized fashion. One of the communication devices is a transponder, which transmits a test signal ( ) to the other communication device ( or ), wherein the other communication device ( or ) derives energy from the electromagnetic test signal ( ) and generates a test response signal ( ) for the transponder ( ) so that the electronic authorization verification device detects the unauthorized removal or the installation of an unauthorized component ( ), and wherein a warning/actuating device either blocks the component ( ) that is installed in the transportation device with regard to its function or transmits an alarm signal.

Component replacement warning system

An electronic closure system has one or more lockable and unlockable closure units, each arranged on an opening element of an object to be secured, at least one authorizing authentication element and a closure control unit with at least one authentication element identification sensor. The at least one authentication element identification sensor has a predetermined detection area, which covers an external detection zone outside the object. The closure control unit produces different closure control commands, related to locking and/or unlocking, based on whether and in what external detection zone authorizing authentication element is detected. The closure control unit contains a sensor system for determining the range of an identified authentication element from the object and, on identification of an authorizing authentication element, automatically produces different closure control commands for the respective closure unit, as a function of the range between the identified authentication element and the object.

Electronic closure system, in particular a vehicle closure system

A vehicle security system has an access monitoring device which includes an access control part and/or an electronic immobilizing device which comprises an immobilizer control part, located on the vehicle. An authentication device can be carried by the user for actuation, subject to authentication, of the respective control part on the vehicle via an associated wireless actuation communication channel. Both an actuation communication channel which needs a key, and a wireless actuation communication channel which needs no key (and communicates based on proximity, without manual actuation) are provided for actuating a control part on the vehicle, optionally via one or the other actuation communication channel. The actuation communication channel which requires a key is given priority over the corresponding actuation communication channel which needs no key.
