AI Technical Summary
Technical Problem
Existing wireless update campaigns for vehicles are slowed down by group-based or wave-like distribution methods, which increase the execution time and risk of failure due to simultaneous updates across a fleet.
Method used
An update system that distributes wireless updates to a constant number of vehicles simultaneously, adjusting based on status information and failure risk values to minimize the risk of failure and reduce execution time.
Benefits of technology
The system reduces the time required for update campaigns while minimizing the risk of hardware or software failure by maintaining a consistent number of vehicles receiving updates and adapting to failure rates.

Abstract
Update system (1) for rolling out wireless updates to vehicles (2), comprising a vehicle fleet (3) with a plurality of vehicles (2) and a central computing unit (4), wherein the central computing unit (4) is configured to distribute a wireless update to the vehicles (2) using a wireless communication channel, and the vehicles (2) are configured to receive the wireless update from the central computing unit (4) and to implement a respective wireless update in a vehicle-internal computing unit (5), wherein the central computing unit (4) is further configured to: - determine or receive a distribution set (6) and an installation set (7),The distribution set (6) defines a selection of vehicles (2) of the vehicle fleet (3) to which the wireless update is to be rolled out, and the installation set (7) defines a subset of the vehicles (2) assigned to the distribution set (6) that are to implement the wireless update simultaneously; - to distribute the wireless update to the vehicles (2) assigned to the installation set (7) and to implement it there, wherein the respective vehicles (2) are configured to transmit status information to the central computing unit (4), including at least information on whether the respective wireless update was successfully implemented on the respective vehicle-internal computing unit (5) or whether the update failed; and - taking into account the respective status information, to keep the installation set (7) constant.so that as soon as the implementation of the wireless update in a vehicle (2) has been completed, the distribution and implementation in the next vehicle (2) of the distribution quantity (6) is started, characterized in that the central computing unit (4) is further configured to receive a failure risk value describing a ratio of an expected quantity of vehicles (2) on which the implementation of the wireless update will fail to the distribution quantity (6), and to determine the installation quantity (7) depending on the failure risk value.
