摘要

WHO’s studies (2003) indicate that every year there are 1.2 million of people dead inrncrash and in the 5.2% of the crashes with people injured, there is a truck involved in it.rnOnly in Spain, crashes cost more than 4.620 million € every year (DGT, 2004). Thisrnproject develops a system that helps to reduce the crash possibility of long vehicles.rnOne date to think about is that when a truck overtakes another one, the one which isrnovertaking needs 28.8 s and a distance of 800 m, if the speed difference between them isrn5 km/h, more or less. Also, with poor visibility or bad weather conditions, the driverrnneeds to have overtaken the other vehicle for a distance bigger than 14 m because of therntruck length and the poor visibility of the exterior mirrors, and this overtaking turns intorna difficult and dangerous manoeuvre.rnThe main objective of this project is to reduce at the minimum possible the staying timernof a truck in the adjacent lane to do an overtaking and guarantee the correct return to therninitial lane, giving enough distance between two vehicles. The designed system isrnformed by different components with the objective of detecting the possibility ofrnturning to the initial lane after doing an overtaking. Four presence sensors are installedrnat the back and side part of the vehicle, one switch which activates the system’srnprocessor (E.C.U.) and one avoidance device which shows the possibility of returning tornthe initial lane after overtaking to the driver.rnIn order to check the electronic unit and the presence sensors there were done static testrnin the laboratory and dynamic test in open road with the system installed on board.rnThese tests demonstrate that the fiability of the system designed is high and contributernto an important increase of the vial security in the vehicle road transport.
