Prevention system for vehicle accidents caused by sun glare, measures sunlight brightness on rear side of vehicle and warns driver when conditions are dangerous for overtaking

摘要

A sensor (4) used to measure the brightness of sunlight (3) on the rear side of the vehicle (2) is connected to an electronic circuit adapted to display a text or light signal on the vehicle dashboard (5), or to generate an audible signal, when the light is of predetermined Lux level at a given measurement angle. This signal indicates to the driver that it is too dangerous to overtake. The system can be adapted to warn drivers of oncoming vehicles (1) that sunlight conditions make it too dangerous to overtake.
