Anti-collision warning system for large road vehicle, detects brake lights on vehicle in front and automatically illuminates additional brake light, before driver has braked

摘要

When there is a queue of traffic, a large vehicle (1) can block the field of view for the driver of another vehicle behind. The rear driver can therefore not see brake lights further up the queue, An optical sensor (8) on the bumper of the large vehicle detects red lights ahead and sends a signal (26) to a switch (27) which illuminates an extra brake light (11) on the rear, regardless of whether the driver of the large vehicle has braked.
