Abstract:
Introducing high-definition headlamp systems in the automotive industry opens up a wide range of possibilities for improving existing and developing new types of dynamic lighting functions. Due to the complexity and subjectivity of light distributions of modern headlamp systems, simulation-based development is indispensable. Strong restrictions regarding the time of day and weather conditions as well as the hardly reproducible traffic situations are further reasons to shift the testing of such systems as much as possible from reality to simulation. This contribution presents a first real-time simulation of high-definition systems in virtual environments. The simulation results are validated by measuring data and evaluated using validated software for simulating static light distributions at night. The performance of the implementation in terms of computational effort is also discussed. As it turns out, the presented implementation is well suited in terms of appearance and computational performance as a basis for a night driving simulation.
