Dynamic windshield sun shade assistance

Abstract

Most of statistics currently show that almost every year a considerable number of accidents are happening due to weather conditions, and with a rate of nearly 78% [1] of them are due to the reflection of sunlight. The motivation of the paper is given by the desire to greatly reduce this percentage by providing assistance to the driver by keeping the conditions for optimum visibility both day and night [2]. This electronic system presented in the current article could be a standard feature in ADAS (Advanced Driver-Assistance Systems) in a few years due to integration of several systems that are already present in cars. The system is composed of four distinct entities: a high intensity light source position detection camera which detects any glare or sun reflexions through the windshield, an eye position detection camera that indicates the spot where the windshield must be shaded, the calculation module that contains the algorithms and commands which uses the inputs and generates the response of the system and the liquid crystal display which is the final user for the output and shades out the glares and reflexions. The present paper contains an overview of the system.
