20.500.12556/RUL-130306 Universal safety distance alert device for road vehicles Driving with too short of a safety distance is a common problem in road traffic, often with traffic accidents as a consequence. Research has identified a lack of vehicle-mountable devices for alerting the drivers of trailing vehicles about keeping a sufficient safe distance. The principal requirements for such a device were defined. A conceptual study was performed in order to select the components for the integration of the device. Based on the results of this study, a working prototype of a flexible, self-contained device was designed, built and tested. The device is intended to be mounted on the rear of a vehicle. It uses radar as the primary distance sensor, assisted with a GPS receiver for velocity measurement. A Raspberry Pi single-board computer is used for data acquisition and processing. The alerts are shown on an LED-matrix display mounted on the rear of the host vehicle. The device software is written in Python and provides automatic operation without requiring any user intervention. The tests have shown that the device is usable on almost any motor vehicle and performs reliably in simulated and real traffic. The open issues and possibilities for future improvements are presented in the Discussion. safety distance traffic vehicles sensors radars Raspberry Pi varnostna razdalja promet vozila zaznavala radarji true false true Angleški jezik Slovenski jezik Članek v reviji 2021-09-13 11:47:04 2021-09-13 11:47:06 2023-11-29 10:55:02 0000-00-00 00:00:00 2016 0 0 17 str. iss. 2, art. 19 Vol. 5 2016 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 614.8:656.1(045) 2079-9292 10.3390/electronics5020019 14714139 RAZ_Virant_Matic_2016.pdf RAZ_Virant_Matic_2016.pdf 1 9935CE34D01968E0A482604CA6A21C0F 210067f6447b883ac10edbe46916a13d78f58f4e0e524d9d3d4bdfa8f7e71742 cbae8c81-1477-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=147385 http://www.mdpi.com/2079-9292/5/2/19 1 4dc05361-1477-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=147384 Fakulteta za strojništvo 0 0 0
