The complexity of software in vehicles is increasing exponentially, driven by the full electrification of the powertrain, highly automated driving functions, as well as customer-specific features and value-added services.

In the future, the entire vehicle functionality will be executed on a central powerful control unit in the vehicle using software components from different manufacturers. This is referred to as the Software-Defined Vehicle.
For the continuously safe operation of such a vehicle, the different software components must not interfere with each other, even though they run on the same central computer. This must be guaranteed even when individual software components are exchanged or supplemented during operation. Examples include security updates and the post-installation of new functions (e.g., a fully automated parking assistant).
Here, we present a method for the specification and consistent verification of real-time and resource properties during a seamless update of a driving function in the field also referred to as "Modular Online Update".
