Professional Calibration Data Management

Professional Calibration Data Management with vCDM

Graphic process of managing calibration data
The functions of vCDM support all phases of the calibration process

vCDM is the database-supported platform for calibration teams. Work results are efficiently merged, and potential data conflicts are avoided or detected and resolved. All data changes are seamlessly tracked.

A large number of variants can be controlled by meta data, organization of dependencies, components, automatic calculation of parameter value and re-use of work packages. Datasets are consistent and have high data quality. Data mining and report functions improve the quality and efficiency of your processes.

Calibration data is graphically displayed and manually processed with the proven vCDMstudio editor as a powerful work environment for the calibrator.


  • Team efficiency: Avoid, detect and resolve data conflicts
  • Traceability of all changes
  • Flexibility of vCDM: All application domains and ECU architectures are supported: powertrain and chassis, AUTOSAR Classic and Adaptive, Tier1 and OEM, functional development and simulation
  • The convenient vCDMstudio editor is part of vCDM and can also be used without the database for file-based tasks
  • Domain-specific views visualize specific aspects of the calibration data in an easy to understand form (e.g. Function-Inhibit Editor for OBD)
  • Modern, cloud-ready system architecture and support of globally distributed teams
  • All operations are optimized for a large number of variants

  • Change of user mode: A user who started with the intuitive and guided user mode is able to easily switch to the expert mode later.
  • Integration with calibration tools: Direct start of vCDM functions from calibration tools CANape and INCA without having to leave vCDM.
  • Web browser access: Easy access for external organizations and sporadic users.
  • Integration in company applications: Integration of vCDM into company applications with the help of the COM and SOAP programming interfaces.
  • Domain-specific extension: Function Inhibit Matrix

Special Functions

Vehicles are calibrated by engineers using tools such as CANape or INCA. To ensure that engineers do not have to leave these tools to interact with vCDM, vCDM can be coupled to CANape and INCA:

  • For INCA the standardized eCDM interface is provided.
  • Integration in CANape is highly optimized for specific features and functions of CANape and vCDM.

You can download the latest software revisions of vCDM into the calibration tool and deliver calibration data into vCDM directly from the calibration tool.

Web browser based access is available for limited access to calibration data. This is ideal for providing access to vCDM to external suppliers, shop areas, software developers and other occasional users.

The web browser based access fulfills all usual IT security guidelines, even for communications with external organizations.

vCDM supports two forms of saving calibration data:

  1. Data is saved address-based in Intel-HEX or Motorola S-Record files. This form of data saving is only readable for ECUs.
  2. Data is not saved in physical notation in parameter set files. This notation is easy for calibrators to interpret.

Conversion between the two notations involves the use of A2L files.

The internal database model of vCDM uses the second notation to save all data ECU-independently. This enables wide-ranging analyses in a short period of time, since the data do not need to be converted from the address-based notation to a human readable form.

Extensive reports can be generated within just a few seconds. They output an overview of all changes and their sources, check the consistency of variants and identify optimization potential of parameters.

vCDM in "Software-as-a-Service" mode

Tight IT resources & limited budget

Illustration data management

In contrast to software for measurement and calibration of ECUs, a data management solution is not a single-user based solution. Besides the user access to the PC, vCDM also consists of a server and the database. Like any business solution, vCDM requires the support of the IT department for operation and maintenance. Although the IT effort is low, major challenges in the department often arise in the competition for limited IT resources. In many cases, the result is time delays and additional, high internal costs. Small companies and departments therefore often decide not to use calibration data management – in spite of the technical advantages.

The need for data management frequently emerges from the technical requirements in a project. In the classic software license model, the procurement costs for a data management solution must be paid from the project budget or the purchase must be prepared for well in advance in the budget planning. For this reason, the frequently large inefficiencies resulting from manual data management are accepted because the purchase of a calibration data management solution is not practical.

All Puzzle Parts for OBD Documentation

photo puzzle parts for OBD documentation
Integrated process for generating the legally required On-Board Diagnostics documentation faster and without errors

OBD-II and HD OBD require extensive documentation from manufacturers for approval of new vehicle models by certification authorities. Creating it requires precise knowledge of the legal requirements, details of the implementation of the monitoring functions in the ECU, knowledge of extensive responsibilities, insight into the calibration parameters of the ECU, and much more. Besides the complexity of these tasks, correctness (of form and content) is extremely important, since there is a threat of fines for each approved vehicle.

A structured process for creating OBD documentation supports manufacturers and suppliers in meeting these challenges and makes it possible to build up a knowledge base. An integrated tool like vCDM can support all the engineers involved according to their tasks and makes it possible to reuse existing knowledge in a sensible way. This leads to significant time savings and helps to reduce errors and the associated costs.
