Self-driving Volvos cover 200km of busy Spanish motorway
Real-world test for Project Sartre
Three cars have successfully driven themselves by automatically following a lorry for 125 miles on a public motorway in the presence of other, normal road users.
The real-world trial, conducted in Spain by Volvo and car automation specialist Ricardo, put technology created for Project Sartre (Safe Road Trains for the Environment) to the test to determine if it can indeed allow the cars to be guided safely by a lead vehicle while their drivers get on with something else.
The Sartre tech is designed to allow cars to slot in behind another vehicle which then effectively takes control of the entire train. It's a technique called "vehicle platooning".
On-board cameras, radar and laser tracking allow each vehicle to monitor the one in front. Wirelessly streamed data from the lead vehicle tells each car when to accelerate, break and turn, all in real-world traffic conditions.
"Apart from the software developed as part of the project, it is really only the wireless network installed between the cars that set them apart from other cars available in showrooms today," said Volvo's Sartre project chief, Linda Wahlström.
The 125-mile test run was conducted at an average speed of just over 50mph and kept the three cars behind the truck at an average separation of 6m.
Volvo has tested the technology many times before, but until now only on private test tracks.
"We has slopes… it was quite windy [and there was] a lot of other traffic, and it was great to see the system could handle it," said Ricardo chief engineer Eric Chan. "It was a very positive experience." ®
Who the hell wants to follow a lorry in their car on a motorway??
Now if they can make the lorrys all follow each other and not mess about trying to overtake each other - clogging up the motorway in the process, then I think they'd really be onto something.
I can't see anyone wanting to drive a great distance at 56mph, it'd take forever.
All well and good until something goes wrong.
Indeed. They should be limited to 4 MPH and have someone walk in front waving a red flag.
Re: Slight problem
Another slight problem... What happens when you find yourself coming up to a junction and the lane leading to the exit you want is full of 100 Volvos all 6 meters apart with none of the drivers paying any attention to other road users and letting them in.
