Abstract
An auxiliary visual interface for a vehicle is disclosed, which is designed to expand the traffic view of the driver beyond the driver compartment. The visual interface consists of four video cameras respectively installed at four corners of the vehicle. Through two switching elements, video images from the front-end or rear-end video cameras are simultaneously brought onto two LCD displays arranged on the dash board to enable the driver to preview the traffic conditions around the corner before making the turn or backing out of an alley. The main controller can also be connected to a speed recorder, whereby the upper and lower speed limits are preset to control different display modes. The main controller can also be connected to a back-up detector to measure the relative distance of any object approaching from behind. The present invention promotes driving safety on the road.
