Stuttgart – #Daimler Trucks is consistently driving forward the digitalisation of its trucks. As a result of this, drivers are relieved of stress in their daily work. Also work processes are becoming more efficient and more secure. One area of development in this context is the ability of trucks to autonomously communicate with other machines and carry out legally-binding transactions, such as payments. With the newly created digital Truck-ID and the associated Truck Wallet, experts at #Daimler Trucks have now created the appropriate prerequisites as part of a pilot project. In an initial use case, the developers have joined forces with partners and successfully carried out an automatic payment at an electric charging station.
Trucks can identify themselves to other machines using their Truck-ID as if they had their own integrated ID card and can thus provide a unique signature for specific processes. The #truck Wallet works as a platform technology and central user program for all applications which can access the Truck-ID for various purposes. Truck-ID and #truck Wallet – both currently still in the prototype phase – are stored as encrypted software programs within a cryptographic processor. This processor is part of the #truck Data Center, the central telematics control unit of the new Mercedes-Benz Actros.
Autonomous interaction between trucks and other machines
Dr Helge Königs, head of the #truck Wallet project at #Daimler Trucks: "With Truck-ID and #truck Wallet, we have laid the foundation for autonomous interaction between trucks and other machines – a true technological milestone. Our aim is that, in future, trucks will be able to act on their own behalf in various fields of application. Drivers can then concentrate more on their actual driving tasks and haulage firms benefit from a significant reduction in administration work and more secure processes. This renders it practically impossible to carry out such things as fuel card scams whereby criminals copy a fuel card and spy on the PIN number being entered. Also in terms of highly automated trucks, our prototypes show the direction in which such further developments can go."
Truck Wallet holds cash and cards, just like a real wallet
Just like a real wallet, the #truck Wallet can hold cash for payments and additional cards such as fuel cards and loyalty cards – though all in digital form. The electronic information, which also includes any cash added, is stored directly in the #truck Wallet and can then be transferred to other machines by means of a Wi-Fi connection. This process is secured by means of checks on an online system. The radio technology is a component of the #truck Data Center.
Truck-ID signs all processes – unique assignment to the truck
Besides automation of processes, the biggest advantage of carrying out transactions with the #truck Wallet comes in conjunction with the Truck-ID. The Truck-ID digitally signs all processes of the #truck Wallet and thus serves as a confirmation that the transactions were actually made with the corresponding #truck. Transactions are thus legitimated in this way. In conjunction with specific telematics data which are additionally stored, such as the current location of the #truck, this system offers logistics companies and their business partners a high level of protection against scams. Generation of the individual Truck-ID is carried out using a proven asymmetrical cryptographic procedure. The secret component of the Truck-ID is thus unknown to #Daimler Trucks, the suppliers of the processor and the #truck Data Center or the haulage firms themselves.
Successful pilot implementation: automatic payments
In co-operation with Commerzbank and its "main incubator" research and development unit, #Daimler Trucks has carried out a fully automated payment process with a #truck system. A fully built up #truck was not needed for this; as part of the pilot testing, the appropriate #truck components – mainly the #truck Data Center including the Truck-ID and #truck Wallet – were sufficient. Commerzbank is currently the only bank in Germany to have developed an e-payment system for this purpose. It is based on Corda, which is an established blockchain platform technology for transactions. As part of the payments process, real money in digital, encrypted form is added to the #truck Wallet of the #truck system in the form of e-euros. After a payment is made by the #truck Wallet, the money is uniquely identifiable thanks to the Truck-ID and is then transferred to the recipient. The recipient can then request Commerzbank to transfer this e-money back to its own account. The transaction is validated and stored online by Corda. In this way, the #truck owner can trace whether one of its vehicles has effected a payment. This process is already legally possible today as the system fulfils all requirements of the German Federal Financial Supervisory Authority (BaFin). As part of this, the electronic cash is covered by means of a billing account with Commerzbank and any suspicious transactions can be detected and, in the case of doubt, be submitted to BaFin.
Most varied of applications imaginable
There is a broad range of additional possible applications for the Truck-ID and #truck Wallet:
Further piloting and testing planned
Daimler Trucks continues to drive forward the development of the Truck-ID and #truck Wallet together with co-operation partners and is already planning further piloting and testing of the technology.
Truck Data Center: the centrepiece of the connected truck
Approximately the size of a DIN A5 sheet, the #truck Data Center connectivity module is installed across all brands at #Daimler Trucks on the basis of the internationally standardised electrics/electronics architecture. The module is part of the standard equipment of the Mercedes-Benz Actros. It receives data from the sensors, cameras, etc. in the #truck and evaluates this for the most varied of use cases. What's more, as the interface for all connectivity services, it is responsible for the truck's external communications. Just like a modern smartphone, the #truck Data Center communicates via Bluetooth or 4G with the infrastructure, with other vehicles and other instances which are part of the logistics process. In addition, it provides positioning via GPS.
