Automated, driverless LEAF pulls 3-vehicle trailer at Nissan plant

This is neat...



I wonder if they hired the laid-off humans to do the whistling in the soundtrack!

EV's are good at towing! Reminds me of the boat trailer a friend and I made a few years ago, ForkenSwift was the tow motor during assembly...

Here's ther press release:

Quote:
YOKOHAMA, Japan – Nissan Motor Co., Ltd. today announced the introduction of Intelligent Vehicle Towing (IVT), a fully automated vehicle towing system, at its Oppama Plant.

Nissan has worked on making the relationship between people, cars and society more exciting under its Intelligent Mobility vision, a framework for how cars will be driven, powered, and integrated into society. This new project, which utilizes mapping and communication technologies to link an intelligent and all-electric car to infrastructure, is a step towards the realization of Nissan Intelligent Integration.

About the technology


The IVT system uses a modified Nissan LEAF to autonomously tow trollies carrying finished vehicles between designated loading and unloading points at the plant.

Unlike conventional automatic guided vehicle systems for transporting parts, which often require the installation of rails or extensive use of magnetic tape, this system does not need any special infrastructure to operate. The towing car is equipped with an array of cameras and laser scanners that detect lane markings, curbs and potential obstacles or hazards around the vehicle. By cross-referencing this information with map data, the towing car calculates its own location, negotiating the route to its destination unaided. The towing car travels within the speed limits of the factory, and automatically stops if it detects an obstacle or hazard ahead, before setting off again when it has determined that the road ahead is clear.

The towing route can easily be altered to accommodate changes in production processes or vehicle transport routes. All driverless towing cars are connected to a central traffic control system, which can monitor the location, driving speed, remaining battery and operational status of each vehicle. When two driverless towing cars meet at an intersection, the control system's algorithm determines which car should be given right-of-way, and in case of emergency, the system can stop the vehicles remotely.

Background of development


The Oppama Plant's existing logistics system requires finished vehicles to be transported from the end of the production line to the facility's dedicated wharf by a team of drivers, at which point they are loaded onto ships. Introducing IVT will allow Nissan to improve production efficiency.

Since trial operations of the system began roughly a year ago, more than 1,600 test runs have been carried out at the plant. The data acquired has been utilized to ensure that the system can operate reliably within the plant's premises. A safety system and a fail-safe system have been developed to counter potential risks or unexpected conditions the IVT system may face during autonomous driving, including adverse weather and low light conditions. Nissan will continue to test the system at its Oppama Plant, and will examine the possibility of implementation at other manufacturing facilities both in and outside Japan.

Nissan has been developing autonomous driving technology for decades. In August, the company launched ProPILOT, an award-winning single-lane autonomous driving technology for highway use. IVT further showcases Nissan's holistic approach to mobility, expanding the advantages of driverless technologies beyond personal usage.

The data and know-how obtained through this project will help to enable broader adoption of autonomous driving technology, in order to provide new solutions to our customers, and to our society.

I see a non-standard test mule pulling a trailer at low speeds in a tightly controlled, private manufacturing facility.

That proves nothing for using a production Leaf towing on public streets.

Hummm... Anyone else see the contradiction there? Cameras and laser scanners aren't infrastructure?

I think they may be referring to buried cable in the road for guidance, special paint on the road to allow the car to detect it, or any number of proposed solutions that require money to be spent and stuff to be installed - on or under - the road so that the car works.

No infrastructure, IMHO, means this car will work with any road that already exists .. without having to change or upgrade the road. Upgrades to the car are fair game ...

But that's only my opinion ..

I second that post. Here in Kirkcaldy we built a new hospital with an underground system where autonomous vehicles tow trailers of supplies, linen, food etc, around the hospital. We had to install a guidance and control system into the floor so they could work. That is infrastructure (The basic physical and organizational structures and facilities (e.g. buildings, roads, power supplies) needed for the operation of a society or enterprise. Oxford English Dictionary). Without that they are useless. They cannot go anywhere else in the hospital or grounds.

Somehow I interpreted "haul" as "tow." Pity. tl;dr: Tesla's second row does not fold flat like every car I have ever known: https://transportevolved.com/2016/10...eeded-context/

Of course, but my points are 1) That the "infrastucture" attached to the car might well cost more (and be less reliable) than the sort of infrastructure you describe; and 2) That you really don't WANT your factory hauling vehicles to be able to leave the plant, otherwise they could well leave with (ex) emplyees, and not come back.
