Method for establishing a communication connection between a new vehicle key and a vehicle and system for carrying out the method

A method for establishing a communication connection between a new programmable vehicle key and a vehicle, the method comprising:

• registering, by a user of a mobile communication device, with a training application;
• initiating, by the user of the mobile communication device a key connection process, which comprises
• checking, by a training application, as to whether
• 1) a user is in the vehicle, a backend application has provided a digital permission to connect the new programmable vehicle key to the vehicle for the user, and the user is registered to the training application;
• 2) the new programmable vehicle key is in the vehicle;
• and
• 3) a programmable vehicle key is in the vehicle;
• and
• communicatively connecting, following a successful checking of 1) to 3), the new programmable vehicle key to the vehicle in a coupling step,
• wherein the programmable vehicle key is communicatively connected to the vehicle,
• wherein a mobile communication device comprises a storage medium storing the training application, which is an executable user application, and
• wherein the backend application is in a vehicle backend and is wirelessly communicatively connected to the mobile communication device.

A system comprising:

• a vehicle;
• a vehicle backend allocated to the vehicle;
• a mobile communication device with a storage medium, a programmable vehicle key communicatively connected to the vehicle;
• a programmable new vehicle key that can be communicatively connected to the vehicle;
• a training application having an executable user application stored in the storage medium of the mobile communication device;
• an executable backend application provided in the vehicle backend and wirelessly communicatively connected to the mobile communication device,
• wherein the vehicle has an electronic ignition switch with a key communication interface configured to communicate with the programmable vehicle key and the new programmable vehicle key, and a vehicle infotainment device with a user communication interface configured to communicate with a user,
• wherein the vehicle backend further comprises a telematics application, a database allocated to the executable backend application, and a key data management application,
• wherein the training application is configured as part of a key connection process to
• 1) check whether a user is in the vehicle, a backend application has provided a digital permission to connect the new programmable vehicle key to the vehicle for the user, and the user is registered to the training application;
• 2) check whether the new programmable vehicle key is in the vehicle;
• and
• 3) check whether the programmable vehicle key is in the vehicle,
• wherein the vehicle is configured, following a successful checking of 1) to 3), communicatively couple the new programmable vehicle key to the vehicle in a coupling step.
