This paper proposes to use a Virtual Reality-based night driving simulator as tool to simulate and evaluate an advanced leveling light system. The PC-based night drive simulator visualizes the complex beam patterns of automotive headlights in high detail and in real-time. The user drives a simulated vehicle over a virtual test track at night, while the vehicle motion directly affects the lighting direction of headlights. Thus, the effect of the vehicle dynamics on the lighting can be evaluated directly in the simulator. The system is connected to the control algorithm of the advanced leveling light system, which controls the headlights tilting angle. This provides a close-to-reality simulation of the advanced leveling light system during a simulated drive at night. That way, within the virtual prototyping process of the advanced leveling light system, good combinations of control parameter values can be indentified, based on virtual test drives in the night driving simulator, and the number of real test drives can be reduced significantly. Promising combinations of the control parameter values then can be validated during a real test drive a night.
