Abstract: 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.

Abstract: 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 (6), that can be mounted in, actuated while mounted, and removed from the ignition lock.

Abstract: 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.

Abstract: Component replacement warning system for a transportation mechanism, which monitors the unauthorized removal or installation of a component (2) of the transportation mechanism, wherein the component replacement warning system (1) include a first communication device (3) that is firmly connected to the transportation mechanism, a second communication device (7) that is connected to the component (2), and an electronic authorization verification device that checks whether a component (2), which is connected to the second communication device (7) is installed in the transportation mechanism provided therefor in an authorized fashion.

Abstract: A method for storing odometer reading data in a vehicle having control units which are connected via a data bus. The odometer reading data, which is determined at a particular time by an odometer, is stored in a storage means of a first control unit. This provides an alternative method for tamper-proof storage of odometer reading data and, in particular, improved protection against errors during the transmission of the odometer reading data. The current odometer reading data of at least one further control unit is then stored on the data bus in a storage means. The control units transmit the odometer reading data, which is stored at a particular time, onto the data bus at specific time intervals, and a control unit accepts the odometer reading transmitted onto the data bus if that reading is higher than its stored value, and uses that value for the further counting and storage in the particular control unit.

Abstract: 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.

Abstract: An electronic safety system, particularly a vehicle locking system, has several safety units arranged on an object to be secured, at least one authorizing authentication element, and safety control devices with several object-side authentication element detection sensors. Signal sending devices emit a query data signal in a pertaining acquisition range, which can be received by an authentication element situated in the corresponding acquisition range. The authentication element has devices for returning an authentication response signal.

Abstract: 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.
