2C5-2 Study on Advanced Head-light Distribution Pattern to Enhance Driver's Visibility

抄録

Adaptive Driving Beam (ADB) is being used in the market. It is expected that the technology of detection for pedestrians and the control technology of head-light distribution advances in the future. Therefore, we propose “Advanced ADB” as a new head-light distribution pattern. Advanced ADB enables not only to enhance the driver's visibility without the glare of forward drivers, but also to make the driver recognize pedestrian's location by flashing. The purpose of this study is to establish an evaluation environment in terms of driver's visibility for the design of Advanced ADB. Specifically, we proposed an evaluation method which evaluates driver's behavior and driver's mental workloads quantitatively in using Low-beam, High-beam, ADB and Advanced ADB in a Driving Simulator (DS). At first, we set up the conditions of High-beam, Low-beam, ADB and the advanced ADB in DS. Second, we set up a scenario that a pedestrian crosses from right side to left side when a driver goes straight on a road. In conclusion, we established an evaluation environment to design Advanced ADB by evaluating driver's behavior and driver's mental workloads regarding four head-light distribution patterns.
