husband Half -truck The 70th highway between Columbus, Ouhayu and Indianapolis may appear unnoticed at first glance. But these excavators are part of a leading demo project that can reshape the charging industry in America.
It was launched in April through a joint initiative between Ohio and Transportation departments in Indiana (Points), the project tests the semi -independent “family” technique, where the leading truck run by a human driver is connected to a follower of followers via cryptocurrencies. Signs of the leading truck control the direction of the truck, the hooking, acceleration and the brake; In essence, the follower’s truck mimics what the leading truck does. As one driver is operating effectively two trucks, the fleet capacity extends without doubling the number of employees. Along with the country’s continuous truck driver’s lack of treatment in the country, safety and improvement can also Fuel consumption efficiency.

“This is related to re -visualization of a future communications In our region, “he says Nick HigimirManaging director of infrastructure and technology in DrivohioSmart Mobility Initiative within Ohio’s point. “Through cooperation through state lines and sectors, we calm the way to a more intelligent, safer and more efficient charging movement.”
What is the truck type?
For the experimental project, Kratos defenseA defensive contractor based in San Diego is known for his autonomy Military systemsAir conditioning technology that tracks the battlefield vehicles for civil use. Trucks are run by Reducing logistics servicesIn Dublin, Ohio.
“We do not replace drivers – we are extending their arrival.”

The Kratos system can be modified to the trucks and is designed to be strong in high overlapping environments. The bilateral communication, the navigation frequencies and 256 bits use AES coding. Trucks can switch between the two radio frequency – 915 MHz and 2.4 GHz – to maintain a safe connection even during their deterioration through electronic fillings, which are often used 915 MHz.
“no Wi-fiThere is no cellular, no Bluetooth, ”he says Mainard workerVice President of Business Development in Kratos. “Just direct Vehicle Connecting with smart reserves if it becomes one unreliable frequency. “
Target coordination works to improve safety by helping to reduce shock waves that can lead to accidents. A follow -up truck also uses up to 10 percent of fuel by staying in the aftermath of a low -pressure truck, while the fuel economy in the leading truck is improving a small percentage because it suffers from less disturbance behind it, according to researchers.
At Ohio-Indiana pilot for a year, a follow-up truck includes a human backup driver. A worker says the system can support backup drivers who do not have a commercial driver’s licenses; The ultimate goal is that there is no driver in the second car. Instead, if both drivers are eligible, they can switch places when the main driver is tired.
“At the end of the day, we do not replace the drivers – we are extending their arrival,” says worker. “We are building a future in which the workforce is supported instead of marginalizing it.”
The pros and cons of truck family
If the family becomes widespread, truck transport companies can save a lot of money. 2021 United States Ministry of Energy Study on the truck family I found that the automatic family at the country level – as trucks from different locations face each other on the road and wirelessly pairing while heading in the same direction – can provide approximately one billion US dollars annually, says fuel. Mohammedhassine NorozoliaAssistant Professor in Civil Engineering in Texas University Rio Grande Valley And the co -author of the study. “It also increases the capacity of the road by about 8 percent, and it may avoid $ 4.8 billion in the costs of expanding the infrastructure,” says Norosolia. The capacity of the trucks allows the distance of the short follow -up of more trucks to travel along a certain extension of the road.
In the experimental project in Ohio -Indiana, the second truck can be approximately 30 meters behind the leading truck – much closer to the human driver who can manage it safely. This is because the follower truck can almost interact immediately if the sudden truck brakes suddenly. On closed tracks and in wind tunnel tests, trucks are less than 4 meters away. But on public roads, state laws require much greater distances.
Noruzoliae warns of the spread of the trucks that are closely used on road erosion. “This may be justified by restricting the family on certain roads – such as local streets or bridges – as the pavement is not designed for these load patterns,” he says. “The state’s points must analyze these bodies when planning the sheets widely.”
Despite the development of the system, Noruzoliae warns that autonomy in the follow -up truck is still under progress. “This technology can reduce the cognitive load and fatigue for the followers,” he says, but the human driver in a dependent truck should remain in a state of alert. Urban environments constitute special challenges. Passengers and traffic lights can dismantle truck factions, forcing truck pairs to repair. This, in turn, takes time and reduces fuel savings.
However, it should make the ready -made nature of the Khatos system attractive to the fleet operators. New capabilities – such as allowing lead trucks and followers to switch parking – can make a more flexible and commercial species.
As the test continues along the I-70 corridor, a familiar roar can indicate advanced truck engines Practical path is increasing to charging automation-especially when compared to the most ambitious vision of full autonomous trucks, such as those recently launched by Pittsburgh Ourora innovation.
Aurora self -driving trucks, which started Dallas and Houston In April, reliance on artificial intelligence, sensor FusionAnd make decisions in the actual time to move in highways without human inputs. But despite rapid progress, Fully independent trucks He still faces great obstacles – organizational, technical and public confidence – which is likely to delay the wide adoption for years. During the first trip of the Aurora truck on public roads, CEO Chris Ormson Participate in the excitement about riding in the back seat. However, a few weeks later – and upon the partner’s insistence – Aurora decided that the human observer sit on the plane in the driver’s seat instead.
While we await the future of the truck without a driver, the semi -independent truck species may provide a more affordable, less risky and close -risk option. Since the Kratos system can be modified to the current trucks, the shipping operator can enter the autonomy into the fleet without the need to invest in new trucks.
“The family is the next step in building a flexible and modern charging network – one safer, more intelligent and more efficient,” says worker.
