Due to new functionalities concerning the longitudinal and lateral guidance the degree of connectivity is increasing. This process is routed on the one hand within the vehicle, e.g. during sensor fusion, on the other hand beyond the vehicle boundaries. In order to guarantee safe mobility regarding the growing degree of communication, new procedures must be developed to ensure reliability in the high variant range of traffic simulations.
At present, testing these new procedures are executed on the actual road. However, for reasons of safety and repeatability (even in threshold areas), the goal must be a virtualization. The vision is therefore a “virtual test field”.

Motivation and Objective

Due to the increased degree of networking and automation, both functional safety and information safety are essential issues in vehicle development.
In addition, new technologies, such as self-learning and adaptive systems, offer great potential for realizing automated driving functions. However, these technologies confront manufacturers and testing facilities with new challenges in terms of development and certification. Generally valid rests for automated driving functions are currently only possible to a limited extent in real environments; the variety of traffic situations and environmental conditions is too large.
Therefore, it is necessary to create maturity statements through simulation and computations. For this purpose, selected real test cases are mapped into simulation scenarios, and the parameter spaces of the vehicle and environmental conditions are simulated in order to be able to carry out comprehensive analyses. In addition, this procedure allows comparable and reproducible statements against increasingly standardized reference test cases.

The validation of connected functions must provide safety and security. For this purpose, concepts for the protection of E/E architectures are developed. In addition, methods are developed to tes E/E architectures and their communication interfaces in a simulated manner for defined requirements (e.g. reliability, security). The results will be transformed into a process of functional validation targeting automated driving function.
In addition, the robustness of a system against unpredictable and non-modellable influences represents a great challenge. Thus, the vehicle must be able to implement appropriate “tail-safe” or “fail-operational” systems.

IIn the early stages of autonomous driving, the handover of the driving function from the system to the driver will be most likely the norm rather than the exception. Current methods of validation will therefore reach their limits. For this purpose new methods of handover will be elaborated and validated within the virtual test field as well.


The aim is to create a virtual test field for automated driving functions which enables scenario-based testing even before real world test runs. The project partners are also involved in the “Test Area Autonomous Driving Baden-Württemberg (TAF-BW)” and offer their experience, which will then be transferred to simulation in order to optimally increase synergies.
