DISPLAY DEVICE FOR PREVENTING REAR-END COLLISION OF VEHICLES

摘要

PURPOSE:To prevent the rear-end collision against the following vehicle by turning a rear reflector at about right angles to the following vehicle at all times regardless of the shape of a road. CONSTITUTION:Respective rear reflectors 2a and 2b are supported on a car body 1 around an upper and lower axes 3 freely turnably. A motor 4 is provided to rotate the reflectors 2a and 2b around the upper and lower axes 3. The curvature of a curved road is detected from a self car speed v0 and a steering wheel angle theta and the distance between the self car and the following car is detected by a radar 6. The operation of the motor 4 is controlled to change the direction of rear reflectors 2a and 2b according to the curvature of the road and the distance between two cars and respective reflectors 2a and 2b are turned at right angles to the following car at all times.
