BARCELONA, SPAIN – The quest to develop autonomous vehicles saw another milestone May 22 when a convoy of self-driving Volvos completed a 125-mile trip on a public highway just outside of Barcelona.
The test was part of the Safe Road Trains for the Environment (SARTRE) Project, funded by the European Commission. A professional driver set the pace in the lead and was followed by four self-driven Volvo vehicles, including a second truck and three cars. The Volvo truck and cars – including an XC60, V60 and S60 – were wirelessly linked to each other and maintained a speed of about 52 mph. The self-driving vehicles used radar, laser sensors, cameras and wireless communications to mimic the movements of the lead vehicle.
