Narayanan, S., Palraj, S., Mani, M., and Pathak, S., "Automotive Vision & Obstruction Assessment For Driver," SAE Technical Paper 2017-26-0012, 2017, doi:10.4271/2017-26-0012.
This paper makes an attempt to focus on a study to evaluate angle of vision and obstruction in a vehicle, it is an objective assessment through different percentiles of population. In a view of Safety and comfort of a driver, a good perception of environment in which his vehicle is operating will be a determining component.Driver visibility and hidden corner in vehicle is a major safety area for passengers and pedestrian. Driver eye vision is an important key factor to design vehicle windshield, rear window and A-Pillar/ B-Pillar, positioning of side view mirror and IRVM based on anthropometry data.This study focuses on method of capturing and measuring the i)Driver's Direct field of vision that the driver sees directly by moving his/her eyesii)Driver's Indirect field of vision in which driver views indirectly by using imaging devices Rear View mirror, Display cameras.iii)Driver's Angle of obstruction - by A pillar, B pillar.This is done by using SAE manikin with vision angle device across different percentile as per SAE J941 Eye ellipse method. This gives objective values of vision angle and windshield vision area for different percentiles.This will help to establish subjective to objective correlation of vision angle and area of obstruction, which can significantly detect the issues pertaining to field of vision. The study will further support in resolving design issues of mirror, sun visor, wiper, defroster requirements.
