Diagnostic System DiaMon: Automated Vehicle Monitoring Using A Diagnostic Control Centre

An important challenge for current diagnostic systems is the early detection of troubles or failures in a vehicle.

This early detection must ideally be done in an automatic way and without support by a technician. This is supported by the newest generation of the diagnostic system DiaMon.

Current vehicle generations in the area of commercial vehicles are equipped with numerous interfaces to provide data for vehicle monitoring and diagnostics to the back office. Information from various sensors and data storages are either uploaded by the vehicle to a central server or retrieved by the server from the vehicle. Dependent on the interface in use, this transmission can be done via UMTS, WIFI, or Bluetooth.

The so-called Diagnostic Control Centre – based on the current DiaMon Release 3.8 – allows to monitor and supervise any number of vehicles and machines of various types and brands. For this, vehicle data is automatically retrieved via the vehicle’s diagnostic interface. The data is evaluated and analysed in the Diagnostic Control Centre. For each vehicle or vehicle type, measurement values and performance indicators to supervise can be individually configured, including allowed ranges, thresholds, and rules for the indication of problems.

The Diagnostic Control Centre can be run either on a back-office server or on a computer inside the vehicle. The user interface of the Diagnostic Control Centre can be configured to show an entire fleet or a single vehicle. If a problem is detected, the responsible colleague will be notified by visual display, e-mail or SMS.

After identification of a problem, the Diagnostic Control Centre supports the expert in the back office to retrieve additional data from the vehicle and thus to provide additional information for the service technician’s preparation of his task.

The current generation of DiaMon is not only supporting Diagnostic Control Centres 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.

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.
