Projects have included truck platooning; improved steering control of GPS-guided farm tractors; driver assistance systems, vehicle and driver monitoring; and navigation and control of unmanned ground vehicles.<\/p>\n<p>In the case of truck platooning, researchers take low-cost commercial sensors on production vehicles and conceive intelligent ways of fusing data together through smart algorithms developed in the lab to enable close-gap following to improve fuel economy \u2013 as much as a 5 percent savings \u2013 and safety.<\/p>\n<p><a href=\"http:\/\/ecm.eng.auburn.edu\/wp\/emag\/files\/2018\/12\/GavNav_MJH_2710.jpg\"><img loading=\"lazy\" class=\"alignnone wp-image-5567 size-full\" src=\"http:\/\/ecm.eng.auburn.edu\/wp\/emag\/files\/2018\/12\/GavNav_MJH_2710.jpg\" alt=\"An Auburn University students monitors truck platooning testing on a laptop computer. \" width=\"1478\" height=\"984\" \/><\/a><\/p>\n<p>\u201cIt improves the safety for the driver of the trucks, it improves the safety for the people around the trucks while improving fuel savings for the fleet owners operating these trucks, which improves the bottom line. And, ultimately, if you\u2019re cutting fuel you\u2019re reducing emissions. It has benefits sweeping across a wide range of things,\u201d said Bevly, who has served as principal or co-principal investigator on more than $20 million in extramurally funded research and holds three patents related to GPS technology and vehicle control.<\/p>\n<p>As a result of this research, Auburn is one of six organizations involved in a two-year study assembled by the American Center for Mobility to further research and test automated convoy platooning using military and commercial grade trucks.<\/p>\n<p>The study aims to autonomously control an entire fleet of commercial and military vehicles \u2013 braking, throttling and steering \u2013 while optimizing fuel efficiency and safety. It is the first study of this scope attempted in the United States.<\/p>\n<p>Meanwhile in Canada, Auburn University and two of its research partners recently made history by conducting the first ever on-road commercial truck platooning trial in the Great White North.<\/p>\n<div class=\"video-container\" style=\"margin-bottom: 15px;\"><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/XQp8PUVQtzg\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/div>\n<p>In concert with FPInnovations and Transport Canada, Auburn researchers conducted successful highway platooning tests Oct. 29 through Nov. 2 on highways around Montreal and surrounding areas in Quebec. The platoon consisted of two heavy-duty transport trucks.<\/p>\n<p>Auburn has tested its truck platooning technology on U.S. highways before, but these tests offered a new environment for testing.<\/p>\n<p>\u201cThe system combines sensors, measurements from a radar and GPS data with other vehicle information such as brake and throttle status shared over a dedicated short range communication radio in order to maintain accurate gap spacing and enable safe platooning,\u201d Bevly said. \u201cWe believe the testing we were able to perform in conjunction with our Canadian partners helped us move forward in validating the technology. Specifically, it provided us with a unique opportunity here to test in conditions that were new to us, and are grateful for the assistance of Transport Canada and FPInnovations.\u201d<\/p>\n<p>A distance of between 65 to 100 feet was kept between the two trucks, which allows a passenger vehicle to safely cut in between the vehicles. The truck platoon travelled several hundred miles on highways with normal vehicular traffic.<\/p>\n<figure id=\"attachment_5568\" aria-describedby=\"caption-attachment-5568\" style=\"width: 1200px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/ecm.eng.auburn.edu\/wp\/emag\/files\/2018\/12\/NCAT-Track-Aerials-5-of-5.jpg\"><img loading=\"lazy\" class=\"wp-image-5568 size-full\" src=\"http:\/\/ecm.eng.auburn.edu\/wp\/emag\/files\/2018\/12\/NCAT-Track-Aerials-5-of-5.jpg\" alt=\"The National Center for Asphalt Technology\u2019s 1.7-mile test track.\" width=\"1200\" height=\"900\" \/><\/a><figcaption id=\"caption-attachment-5568\" class=\"wp-caption-text\">Much of the GAVLAB research is conducted at the National Center for Asphalt Technology\u2019s 1.7-mile test track, with some recently being tested across the Canadian border.<\/figcaption><\/figure>\n<p>\u201cAuburn\u2019s system proved to be very reliable even in the rainy and snowy conditions we experienced. We were able to spend most of our time on the road with the platooning mode engaged,\u201d said Edouard Proust, a PIT Group engineer with FPInnovations. \u201cThis is a great achievement. It\u2019s a little soon to make a conclusion on the data that was gathered, but the system reacted properly to vehicle cut-ins and to road conditions.\u201d<\/p>\n<p>In addition to truck platooning, GAVLAB research also centers on methods for assured positioning, navigation and timing.<\/p>\n<p>\u201cWhile GPS provides us very accurate navigation information when available, it can be degraded in some environments with heavy foliage or urban canyons where buildings block the signals,\u201d said Scott Martin, assistant research professor. \u201cWe\u2019re working to improve the availability of GPS and to improve accuracy of the navigation solutions by combining GPS with additional sensors, cameras, lidar and radar commonly found on production vehicles that can be used to improve the robustness of our solutions.\u201d<\/p>\n<p>These solutions could be used to assist navigation for vehicles, pedestrians and the visually impaired.<\/p>\n<p>\u201cPositioning has become ubiquitous,\u201d Bevly said. \u201cWe want to know where we\u2019re at or how to get somewhere, and we want that all the time. We expect it now.\u201d<\/p>\n<p>In addition to the research being conducted, the GAVLAB is also producing the next generation of engineers and navigation experts who can go into industry and help solve these critical problems. These engineering graduates have gone on to work for the defense industry, Tesla, Delphi, Draper and others.<\/p>\n<p>GAVLAB\u2019s research facilities include the National Center for Asphalt Technology\u2019s test track, a 1.7-mile oval track jointly operated by Auburn University and the National Asphalt Pavement Association, as well as several drive by-wire and automated vehicles that include two Peterbilt tractors, a Lincoln MKZ and an autonomous ATV.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Each day, people rely on hundreds of GPS, navigation and timing devices and instruments to assist in everything from driving directions to counting steps.
