DOCT - DIGITAL OTA CONNECTIVITY TWIN

The vehicle of the future is digital and connected. Automated driving and entertainment applications used in parallel are setting increasingly complex demands on modern connectivity systems. To ensure the reliability of these systems and at the same time improve their performance, a wide range of measurement and testing procedures is required. Today, these tests are complex, time-consuming and expensive. Nevertheless, they deliver incomplete and hardly reproducible results.

The DOCT research project aims to significantly increase the safety of in-vehicle connectivity systems by creating a high-performance development environment. A fast and nearly complete qualification of secure and robust radio systems for automated driving and OTA data applications will thus become possible.

The "digital twin" is the image of a radio scenario portfolio optimized for the project and thus of the complex radio environment. This portfolio is composed of the radio scenarios of the partners, which are redundancy-filtered by AI methods and completed by extrapolation in frequencies and modulation standards. The "digital twin" is then tested and evaluated in a measurement chamber on the vehicle as part of a proof-of-concept.
