Abstract

Various technologies are being developed to support safe driving. Among them, ADAS, including LDWS, is becoming increasingly common. This driver assistance system aims to create a safe road environment while compensating for the driver’s carelessness. The driver is affected by external environmental factors such as rainfall, snowfall, and bad weather conditions. ADAS is designed to recognize the surrounding situation and enable safe driving by using sensors, but it does not operate normally in bad weather conditions. In this study, we quantitatively measured the effect of bad weather conditions on the actual ADAS function. Additionally, we conducted a vehicle-based driving experiment to suggest an improvement plan for safer driving. In the driving experiment, when the vehicle driving speed was changed in four stages of rainfall, it was confirmed that it affected the View Range value, where the primary variable is the visibility of ADAS. As a result of the analysis, we demonstrated that when the rainfall exceeded a precipitation of 20 mm, the ADAS sensor did not operate, regardless of the vehicle speed. This means that a problem affecting safe driving may occur due to functionality in bad weather situations in which the driver requires ADAS assistance. Therefore, it is necessary to develop a technology that can maintain the minimum ADAS functionality under rainfall conditions and other bad weather conditions.

Highlights

The lane departure warning system (LDWS) is one of the mechanisms of advanced driver assistance systems (ADAS) that increase driving safety by providing a warning to the driver when a vehicle driving on the road leaves the driving lane
As a result of reviewing the existing standards, all standards except for “KS R 1172”, one of Korea’s performance test method standards, require performance tests of equipment to be carried out based on the results determined for ideal conditions
This means that drivers may not receive assistance in situations that require assistance for safe driving in bad weather conditions

Summary

Introduction

The lane departure warning system (LDWS) is one of the mechanisms of advanced driver assistance systems (ADAS) that increase driving safety by providing a warning to the driver when a vehicle driving on the road leaves the driving lane. Most current traffic accidents are caused by the driver’s carelessness. The various technologies constituting ADAS can be said to be the main technologies for safe driving and securing safety on the road [1,2,3]. In Korea, LDWS, one of the ADAS technologies, has been installed in some luxury vehicles to support safe driving. In recent years, as large-scale traffic accidents have occurred due to the carelessness of the drivers of trucks and heavy transport vehicles, LDWS installation has been mandatory for buses and trucks since July 2017 to prevent accidents [6]
