Onboard Diagnostics for Vehicles
Diagnostic System DiaMon
As a consequence of high variance of types and functions in vehicles, After-Sales must provide and keep up to date an enormous number of diagnostic knowledge bases for workshop technicians to cover all variants that may occur in the field. If it is possible to relocate the diagnostic system for a specific vehicle into that vehicle, every technician will be able to service every vehicle without specific preparation. In the current DiaMon Release 3.8, the necessary framework for this scenario has been designed and prototypically implemented.
The availability of powerful minicomputers allows to integrate these into the existing architecture of various vehicles and machines. These provide the opportunity to run After-Sales applications related to diagnostic tasks directly inside the vehicle, and thus to support new application scenarios.
In order to provide a cost-efficient alternative to conventional diagnostics on a technician’s notebook, the runtime system of the diagnostic system DiaMon has been ported to the cost-free Linux distribution Ubuntu. Components and libraries specific to Windows have been adapted or exchanged so that the current DiaMon Release 3.8 is now able to run on Windows as well as on Linux. Thus, there are no additional licence costs for an operating system in addition to the hardware cost.
The current generation of DiaMon is not only supporting onboard usage but also further scenarios. On the one hand, cooperative diagnostics allow that a technician can easily be supported by an expert from the back-office when analysing a problem at a vehicle. On the other hand, a technician may use further auxiliary tools like e. g. data glasses in order to view a vehicle from two perspectives. Finally, DiaMon’s diagnostic control centre allows to diagnostically supervise an entire vehicle fleet in an automated mode.
These different scenarios have been made possible by a clear separation of the diagnostic system into a web service based diagnostic server and various thin clients. The diagnostic server may be placed either on a technician’s notebook, into a diagnostic ECU in a vehicle, on a centralized server in the OEM’s network, or even in the cloud. The system contains specific mechanisms that guarantee accesses of cooperating clients to a vehicle to be synchronized and thus free of conflicts.
