| ABSTRACT |
|
Advanced driver assistance systems are an important step on the way towards the autonomous driving.
However, there are new challenges in the release of increasingly complex systems. For the testing of those systems many test
kilometers are necessary to represent sufficient diversity. Hence, the virtual testing of driver assistance systems brings new
opportunities. In virtual environments, it is possible to run a much higher distance in a short time. Simultaneously, the .
complexity of the environment and the test scenarios are individually adjustable. It is possible to test scenarios that are not
feasible in a real environment due to a risk of injury. A big challenge is the physical correct implementation of real vehicles
and their components into the Virtual Reality. To enable a realistic virtual testing the vehicles surrounding sensors need to be
modeled adequately. Thus, this paper presents an approach for the implementation of a Lidar model into a Virtual Reality. A
physical Lidar model is combined with a real-time capable vehicle dynamics model to investigate the influence of vehicle
movements to the sensor measurements. The models are implemented into a highly realistic virtual city environment. Finally,
a test campaign shows the influence of the Lidars physics and the vehicle dynamics on the detection results. |
