A novel concept for providing early or anticipatory indication and / or warning, to the driver of an automobile and the vehicle (s) which are following close behind (travelling in same direction) , for avoiding possibility of collision in situations arising due to sudden braking or slowing down of the leading vehicle (s) or vehicle(s) in front.

摘要

This invention relates to a simple concept which can prove very useful in congested traffic situations, bumper to bumper traffic in majority of cities and also on Highways wherein the traffic density is comparatively higher. The subject vehicle is equipped with a proximity sensor (In the front side of vehicle) a data processing & control unit (hereafter called as DPCU) based on microcontroller. DPCU is also connected to an audible and/or visible warning system located suitably inside the subject vehicle so that driver can see or hear the warning and/or an audible and/or visual warning system located at the rear side of “Subject Vehicle” suitably so that the drivers of the vehicle(s) following the “Subject Vehicle” in traffic can see and/ or hear the warning being communicated from DPCU. The warning signal is communicated by DPCU when the vehicle(s) leading the subject vehicle in same direction of travel brakes abruptly or slows down due to traffic conditions. The sensors sense the vehicle proximity in front and the DPCU calculates the rate of change in distance between two vehicles. Based the algorithms programmed in DPCU it initiates the warning signal which alerts the drivers in advance. Based on these warnings the vehicles may be slowed down or appropriate actions can be taken by the drivers of vehicle(s)
