Autonomous road train project

leave a comment

The sucessfull results of the  SARTRE (Safe Road Trains for the Environment) project represents the beginning of a new era where the organized chaos of individual drivers can be blunted by an autonomous “follow-the-leader” approach that has clear benefits: As well as freeing up the driver from the hassle of actually controlling the vehicle, the  project promises benefits in terms of safety, congestion (meaning faster travel times) and fuel consumption, which could be reduced by as much as 20 percent on the highway.

Part-funded by the European Commission, SARTRE is a joint venture between Ricardo UK Ltd, Applus Idiada, Robotiker, Institut für Kraftfahrzeuge Aachen (IKA), SP Technical Research Institute, Volvo Technology and Volvo Car Corporation. It works by using a high-tech suite of cameras, radar and laser sensors to enable a wirelessly linked “platoon” of cars to travel autonomously in a road train behind a lead vehicle operated by a professional driver.

The project started in 2009 and the technology was successfully demonstrated at the Volvo Proving Ground near Gothenburg, Sweden, back in 2010. In the latest milestone, the SARTRE platoon took to the motorways of Spain amidst other road users in a journey that saw a Volvo XC60, a Volvo V60, a Volvo S60 and one truck drive automatically behind the lead vehicle at 85 km/h (53 mph) separated by a distance of as little as five meters (16.4 feet). Using Ricardo’s autonomous control system, each of the vehicles was able to accelerate, brake and turn in exactly the same fashion as the lead vehicle.

“People think that autonomous driving is science fiction, but the fact is that the technology is already here,” says Linda Wahlström, project manager for the SARTRE project at Volvo Car Corporation.

Intelligent goggles for partly-sighted people

leave a comment

“Intelligent” goggles for partly-sighted people have been developed at Universidad Carlos III in Madrid, Spain. The system consists of a pair of stereoscopic digital cameras mounted on either side of a virtual reality headset, with two digital screens in front of the wearer’s eyes in place of lenses. The cameras scan the field of vision in front of the headset, convert it to digital code and then feed this to a separate computer package. The computer then runs an algorithm developed by the team, that determines the distance and outline of any objects seen. What the cameras scan is displayed on the headset’s screens and information about the objects is conveyed to the wearer by overlaying them with color-coded silhouettes.

“It detects objects and people who move within the visual field that a person with no visual pathologies would have,” said Professor Vergaz, leader of the research team who has developed the “intelligent” goggles. “Very often the patient does not detect them due to problems of contrast. The information regarding depth is what is most missed by patients who use this type of technical aid.”
