Abstract

The invention relates to a system for managing an authorization for a vehicle, comprising: a vehicle memory module having a key list, which contains a plurality of entries for a plurality of digital keys, which can be allocated to individual users by means of a first electronic device, each digital key constituting a vehicle authorization for a user, and each entry in the key list being assigned a one-time identifier; and a communication module, which is designed to transfer at least one identifier assigned to an unallocated entry from the vehicle to the first electronic device.

Description

technical field [0001] The present disclosure relates to systems and methods for managing authorizations for vehicles, particularly motor vehicles. In particular, the present disclosure relates to the secure distribution of access authorizations and / or engine start authorizations to multiple users. Background technique [0002] Mobile identification transmitters (Identifikationsgeber) can be used to unlock the vehicle contactlessly, thus enabling the user of the identification transmitter to enter the vehicle. Typically, a system is used in which authentication data is transmitted wirelessly. In the event of a positive verification of the vehicle, the doors and / or the trunk are automatically unlocked. Additionally, engine start may be authorized or allowed. [0003] Mobile end devices such as smartphones can be used as mobile identity transmitters. For example, the car owner can forward the digital key to other users' mobile terminal devices (also called "third-party ter...
