Abstract:
ADAS including LDWS which is designed to support the driver for safe driving has been generalized and used more widely. Such system is intended to supplement driver's carelessness so as to create safe road environment, and viewing from such standpoint, it shall be able to help the driver run safety even at the inclement weather condition such as torrential rain, heavy snow or foggy condition.
But at real rainy weather condition, ADAS is often not functional correctly, failing to provide the assistance. This study is meaningful that it quantitatively measured the effect of rainfall on ADAS performance.
To that end, while the vehicle runs at 60km/h, 48km/h and 30km/h at 4 stages of rainy condition, the change to view range which corresponds to ADAS visibility was monitored. As a result, when the rainfall exceeded 20mm, ADAS sensor became not functional.
The experiment indicated that ADAS failed to function properly at inclement weather condition when the driver was really in need of help by ADAS. Such experiment result indicated the need of technical development which is able to maintain ADAS function at the least at the inclement weather.
