Towards Homologation of Sensors, Sensor Fusion and Automated Driving Function: the Role of high fidelity Environment Modeling
- Advanced driver assistance systems (ADAS), Highly Automated Driving Functions (HAD) and Autonomous Driving (AD) provide among comfort to the driver also a great potential for future mobility and tends to increase traffic and car safety. All ADAS, HAD and AD functions and especially those associated with high safety levels, require paradigm-changing approaches for the homologation: some ADAS and AD functions require up to about 200 million km of real drive testing for the qualification. This amount of real drive testing is not feasible for any OEM and therefore there is a strong need for a mixed test strategy where the performed real drive tests take credit from a virtual campaign evaluation. Such a combined real and virtual test strategy could reduce the necessary efforts for the qualification of a given function development and its validation.
To support virtual testing, the triangle of the driver, the vehicle and the environment has to be modeled for simulation.

To support virtual testing, the triangle of the driver, the vehicle and the environment has to be modeled for simulation. The interface between the vehicle and the environment, i.e. a sensor that is a device to transform physical information into electrical signals, is of crucial importance for the ADAS, HAD and AD function, because it replaces step by step the perception of the driver in the car.
This presentation gives a survey about the challenges of the modeling of sensors and their interaction with the fusion strategy and the automated driving functions and the crucial role of high fidelity environment models in order to get confidence in the simulations as a part for the homologation.
The presentations lists also first insights in results of the environment modeling of the city of Kempten/Allgäu.…
