Volvo Trucks & Renova Testing Autonomous Garbage Trucks
Volvo Trucks and the Sweden-based waste management company Renova have begun testing autonomous refuse/garbage trucks, with the intent of improving the safety of such vehicles, according to a new press release from the companies.
The autonomous vehicle tech systems being tested now are the same ones (for the most part) that have been undergoing testing in the Kristineberg Mine in northern Sweden since late last year, according to Volvo.
The autonomous refuse/garbage truck uses GPS and LiDAR, but also relies on previous manual operation along its work route for data — in other words, when a route is being traveled for the first time, it is done manually, providing the system with the knowledge of where to stop, etc.
The Traffic & Product Safety Director at Volvo Trucks, Carl Johan Almqvist, commented:
“Driving a heavy commercial vehicle in an urban residential area with narrow streets and vulnerable road users naturally imposes major demands on safety, even when the vehicle’s speed doesn’t exceed a normal walking pace. The refuse truck we are now testing continuously monitors its surroundings and immediately stops if an obstacle suddenly appears on the road. At the same time, the automated system creates better prerequisites for the driver to keep a watchful eye on everything that happens near the truck.”
Overall, it’s a pretty interesting sounding idea. The current pilot project is expected to continue until the end of the year. This will be followed by a period of analysis and evaluation.
There’s no word of the trial period using electric vehicles, but it seems only logical that’s where things will head eventually.
Here are several more details on the trial program straight from Volvo Trucks:
The first time the automated refuse truck is used in a new area, it is driven manually while the on-board system constantly monitors and maps the route with the help of sensors and GPS technology. The next time the truck enters the same area, it knows exactly which route to follow and at which bins it has to stop.
At the first stop with the automated system activated, the driver climbs out of the cab, goes to the rear of the truck, brings out the wheelie-bin and empties it exactly the way the job is done today by operating the relevant controls. When the operation is completed, the truck automatically reverses to the next bin upon receiving the driver’s command. The driver walks the very same route that the truck takes and thus always has full view of what’s happening in the direction of travel. But why reverse instead of driving forward?
“By reversing the truck, the driver can constantly remain close to the compactor unit instead of having to repeatedly walk between the rear and the cab every time the truck is on the move. And since the driver doesn’t have to climb in and out of the cab at every start and stop, there’s less risk of work related injuries such as strain on the knees and other joints,” says Hans Zachrisson, Strategic Development Manager at Renova.
Reversing is otherwise a fairly risky manoeuvre since the driver may find it difficult to see who or what is moving behind the vehicle, even if it is fitted with a camera. In certain areas it is not allowed to reverse with a heavy commercial vehicle for safety reasons, in others it is a requirement that a co-driver must stand behind the truck to ensure that the road is clear before the vehicle is allowed to reverse. The solution being tested is designed to eliminate these issues. Since sensors monitor the area all around the refuse truck, driving is equally safe no matter the direction in which the vehicle is moving. And if for instance the street is blocked by a parked car, the refuse truck can automatically drive around the obstruction provided there is sufficient space alongside.
Since the automated systems optimise gear changes, steering and speed, fuel consumption and emissions can also be reduced.
Vehicles with varying degrees of automation will probably be introduced earlier in other applications, where transport assignments take place within strictly confined areas such as mines and cargo terminals, the company said.
