Concept for Provision of a Key Signal or an Immobilizer Signal for a Vehicle

A method for a central computer, the method comprising:

• providing information relating to the release of a key signal or of an immobilizer signal to a device of a vehicle via a wireless mobile communication system,
• wherein the release of the key signal indicates release, by the central computer, of a function for unlocking or locking the vehicle, and/or
• wherein the release of the immobilizer signal indicates release, by the central computer, of a function for deactivating or activating an immobilizer,
• wherein the release relates to a key signal or an immobilizer signal that is provided to an immobilizer circuit or central locking system of the vehicle via a wireless communication link inside the vehicle if the key signal or immobilizer signal is released by the central computer.

A device for a vehicle, the device comprising:

• a key chip;
• at least one interface that is configured to communicate via a wireless mobile communication system;
• and
• a control circuit that is configured to:
• obtain information relating to the release of a key signal or of an immobilizer signal from a central computer via the wireless mobile communication system,
• wherein the release of the key signal indicates release, by the central computer, of a function for unlocking or locking the vehicle,
• and/or wherein the release of the immobilizer signal indicates release, by the central computer, of a function for deactivating or activating an immobilizer, and to
• provide a control signal to the key chip based on the information relating to the release of the key signal or of the immobilizer signal, wherein the control signal is configured to allow the key chip to generate the key signal or the immobilizer signal,
• wherein key chip is configured to provide the key signal and/or the immobilizer signal to a central locking system and/or an immobilizer system of the vehicle via a wireless communication link after obtaining the control signal.

A device for a central computer, the device comprising:

• at least one interface that is configured to
• communicate via a wireless mobile communication system;
• and
• a control circuit that is configured to:
• provide information relating to the release of a key signal or of an immobilizer signal to a device of a vehicle via the wireless mobile communication system,
• wherein the release of the key signal indicates release, by the central computer, of a function for unlocking or locking the vehicle, and/or
• wherein the release of the immobilizer signal indicates release, by the central computer, of a function for deactivating or activating an immobilizer,
• wherein the release relates to a key signal or to an immobilizer signal that is provided to an immobilizer circuit or central locking system of the vehicle via a wireless communication link inside the vehicle if the key signal or immobilizer signal is released by the central computer.

A device for a mobile device, the device comprising:

• at least one interface that is configured to communicate via a wireless communication link;
• and
• a control circuit that is configured to:
• provide identity information of a user of a vehicle from the mobile device of the user to a device of the vehicle via the wireless communication link,
• wherein the identity information is provided to the device of the vehicle in order to be compared with information relating to a user for whom a key signal or an immobilizer signal is to be released, such that the key signal or immobilizer signal is provided to an immobilizer circuit or central locking system of the vehicle via a wireless communication link inside the vehicle if the information relating to the user matches the identity information.
