A vehicle remote-operation apparatus is provided which transmits a regular authentication request signal from a vehicle-outside antenna and simultaneously transmits an interference wave for negating this authentication request signal from a vehicle-inside antenna, so that the communicable range can be limited between a radio portable unit allocated an identification code unique to a vehicle and the vehicle-outside antenna. Thereby, authentication communication is established only for a regular communication request.

Vehicle remote-operation apparatus

A first operator control function is activated if it is detected by means of a first sensor that a first physical variable is higher than a predetermined first threshold value. In a similar way, a second operator control function is activated if it is detected by means of a second sensor that a second physical variable is higher than a predetermined second threshold value. A third operator control function is activated if it is detected by means of the first sensor that the first physical variable is higher than a predetermined third threshold value and if at the same time it is detected by means of the second sensor that the second physical variable is higher than a predetermined fourth threshold value, the third threshold value being higher than the first threshold value.

Operator control method and operator control device for a vehicle

A keyless alert system (10/20) is disclosed for use in a car incorporating a keyless control system (100/200) which is formed by a master controller (100) and a remote controller (200) co-operable via an RF communication link. The keyless alert system (10/20) comprises a master alert unit (10) in the master controller (100), a remote alert unit (20) in the remote controller (200), and an alert signal generator (11/210) in each of the alert units (10 & 20) for providing an alert signal while the car engine is running and when the communication link fails by reason of the remote alert unit (20) being separated from the master alert (10) unit beyond a certain distance.

Keyless alert system and method for automobiles

The method involves defining an awakening code for a procedure for temporarily inhibiting identifiers (B). Another awakening code is defined for an identifier identifying procedure. The temporary inhibition procedure is established for controlling the transmission of a specific data frame towards the identifiers by a CPU (4) during the detection of the identifiers in a locked vehicle (V). The data frame incorporates the former code and controls the deactivation of recognition of the latter code by the identifiers.

Method of provisionally inhibiting, when detected in a locked vehicle, a portable remote control box, called identifier, of a hands-free access device

The device has mobile identification transmitters carried by a user, and a transceiver arrangement attached/connected to a motor vehicle. The arrangement includes antennas (A1-A3), which cover an interior and/or parts of an external space of the motor vehicle for data exchange with the identification transmitters, where the device determines a location of one identification transmitters and displays the location to the user. The identification transmitters are provided for transmitting signals i.e. optical and/or acoustic signals, perceptible by the user.

Motor vehicle securing and releasing device, has transceiver arrangement with antennas covering interior and/or parts of external space of vehicle, where device determines and displays location of transmitters to user

Once the release switch is operated via the control unit in the car, a vehicle transmitter for the vehicle interior is triggered to send a passivation signal to an existing identification device (radio key device) in the vehicle. This signal prevents its further participation in authentication communication.

Access control system for vehicles

Es wird ein Verfahren zur Uberprufung der Anwesenheit eines ID-Gebers im Innenraum eines Kraftfahrzeuges beschrieben, wobei der ID-Geber zur drahtlosen Zugangskontrolle und zur drahtlosen Freischaltung eines Motorstart-Schalters dient und im Innenraum des Fahrzeuges mindestens eine Antenne zur Aussendung eines Anwesenheits-Abfragesignals vorhanden ist. Das Verfahren zeichnet sich dadurch aus, das bei laufendem Motor die Aussendung von Anwesenheits-Abfragesignalen uber die mindestens eine Innenraum-Antenne nur nach Auswertung der Information mindestens eines Zustandssensors erfolgt, der den Zustand (Offen/Geschlossen) fur eine Fahrzeugtur, eine Kofferraumklappe, ein Fenster, ein Schiebedach oder ein Verdeck ermittelt. Das Verfahren bewirkt eine Verlangerung der Lebensdauer der Batterie im ID-Geber.

Verfahren zur Überprüfung der Anwesenheit eines ID-Gebers im Innenraum eines Kraftfahrzeuges

The method involves an antenna inside the vehicle sending a presence interrogation signal when the engine is running and only after evaluating the information of at least one state sensor for a vehicle door (open/closed), a trunk lid, a window, a sliding roof or a folding roof. A visual and/or audible warning signal is generated if an identification sender is not present.

Es wird ein Zugangskontrollsystem fur Kraftfahrzeuge beschrieben: DOLLAR A - mit zwei oder mehr benutzerseitig mitfuhrbaren ID-Gebern, DOLLAR A - mit mindestens einer fahrzeugseitigen Sende-/Empfangseinheit fur den Fahrzeugausenraum und mit mindestens einer Sende-/Empfangseinheit fur den Fahrzeuginnenraum zur Durchfuhrung einer drahtlosen Authentifikationskommunikation mit den ID-Gebern, wobei bei erfolgreicher Authentifikation eines ID-Gebers eine oder mehrere Sicherheitseinrichtungen ent-/oder verriegelt werden, DOLLAR A - mit mindestens einem fahrzeugseitigen Ausloseschalter, bei dessen Betatigung zum Zwecke der Entriegelung uber eine fahrzeugseitige Steuereinheit mindestens eine fahrzeugseitige Sende-/Empfangseinheit fur den Fahrzeugausenraum zur Aussendung eines Authentifikations-Startsignals angesteuert wird, wobei der Sende-/Emfangsbereich von mindestens einer Sende-/Empfangseinheit fur den Fahrzeugausenrahmen auch zumindest teilweise in den Fahrzeuginnenraum hineinragt. DOLLAR A Erfindungsgemas wird nach einer Betatigung des Ausloseschalters uber die fahrzeugseitige Steuereinheit mindestens eine fahrzeugseitige Sendeeinheit fur den Fahrzeuginnenraum zur Aussendung eines Passivierungssignals an einem im Fahrzeuginnenraum befindlichen ID-Geber angesteuert, wobei durch dieses Passivierungssignal eine weitere Teilnahme eines im Fahrzeuginnenraum befindlichen ID-Gebers an der Authentifikationskommunikation verhindert wird.
