OCT

Fast and efficient calibration and data acquisition

The Online Calibration Tool combines the classic calibration of ECUs and the integration of further measurement technology with modern access from mobile devices via a browser. By eliminating the need for additional software on users’ devices, the OCT enables quick and easy integration into all measurement setups in the vehicle, on the test bench and in the laboratory.

  • Calibrate, visualize, measure
  • Easy access via web browser
  • Access via mobile devices
  • Simple licensing

In contrast to classic measurement and calibration systems, the OCT combines the functionality of the interface adapter with data communication, processing and storage in one compact module. Data visualization and operation of the device are performed via a web interface. PCs/laptops or mobile devices such as smartphones and tablets can be used for this purpose. No additional software needs to be installed on the device used. Both WiFi and wired Ethernet are available for connection to the end device. Integration into the company network is just as possible as direct connection. For the latter, the OCT provides a DHCP server.

The OCT is equipped with two CAN interfaces supporting the XCP and CCP protocols for calibration of automotive ECUs. Of course, CANraw and CANdbc are also supported. This means that sensors and external measurement technology can also be directly integrated. EtherCAT is available as a further interface. This is used in particular in the test bench environment.

In addition to the external interfaces, further modules are available for data acquisition and processing. The OCT receives position data worldwide via an integrated GNSS chip. The GPS, Glonass, Galileo and Beidou systems are supported. Furthermore, a 6-axis acceleration sensor is installed. Additional functions, such as data logging and mobile radio connection, can be implemented via two USB ports and an SDHC card slot.
A Simulink interface enables the execution of models that can access all available signals and parameters of the internal and external interfaces. This makes it possible to evaluate and adjust calibration values depending on any Simulink algorithms.

Vehicle calibration

Data acquisition, visualization and calibration play an important role in the entire development process. Due to emissions regulations, consumption-optimizing measures and the high complexity of modern comfort functions, the functional scope of control units is constantly growing. Optimization of the devices in these areas is therefore becoming increasingly important.

In modern vehicles, up to 60 control units for the various applications are not uncommon. Many developers already use various simulation tools in their areas to validate their work. After the technical simulation, every development and adaptation concludes with a test in the vehicle or on the test bench.

These tests take place all over the world: On the one hand, different climatic conditions have to be mapped, on the other hand, employees from different locations often work together on the same tasks.

Test bench operation

Test bench trials still play an important role in engine development: In mappings, basic characteristic maps are run in and calibrations are verified. Endurance programs are used to validate and approve components, and consumption and emissions are measured in standard cycles.

The greatest challenge for test bench operators is linking a large number of complex systems. Only smooth communication between all systems allows efficient operation. Here, the focus is also on monitoring all functions at runtime.

Systems currently available on the market offer an extremely high range of functions, which is often too complex for daily work. The OCT offers you the possibility to map tasks occurring at the test bench effectively and economically.

University and other institutions

For efficient and up-to-date knowledge transfer, theoretical phases alternate with practical work in everyday university life. In this way, students mature into scientists who put what they have learned into practice and advance research with inventiveness and creativity. The prerequisite for this is appropriate technical equipment at the universities: The tools used in teaching should correspond to those used in research and industry. On this basis, new teaching, working and research formats can be developed, which often leads to universities becoming pioneers in digitization.

In this context, the OCT makes it possible to provide each student with an internship in which they can also learn the practical work of an engineer from home. This creates new perspectives for interactive learning.
