Abstract

At the Technical University of Darmstadt, a study was performed, to find out, if the additional light output through a laser booster in combination with an LED driving beam results in a higher detection and recognition rate than driving with the LED driving beam alone. For this purpose two measurement methods, a dynamic and a static one, were developed. In the dynamic test the participants were driving with 60 km/h over a 1.2 km straight road, trying to detect test-dummies, simulating pedestrians just besides the road. The dummies were coated with dark paint, with a reflectance of 5%. As an additional test, a large and a small square were fixated on the dummies. After detecting the dummy the subject was then required to identify the position of the smaller square in relation to the bigger square. In the static test the subject and the car were standing still and the dummy was moved towards the subject who had to detect and identify the same object pattern as in the dynamic test.
