A worldwide tightening of exhaust gas standards and continuously shorter powertrain development cycles pose the biggest challenges for test field operations. On the one hand, there is a need to invest in new measurement technologies but, at the same time, the most efficient utilization of existing resources must be achieved. On the other hand, the diversity of test objects (combustion engine, gearbox, electric motor, battery and power train) leads to increasingly complex test benches including the testing tasks. Only by efficient planning of available resources as well as continuous weak point analysis of the processes used in the test field can a future-oriented test be conducted.
Efficient planning of the activities in the test field is based on precise knowledge of the actual state:
- What tasks are being performed on each test bench?
- How long will the test bench operate for the defined project task?
- Which maintenance intervals are pending for the measurement technology being used?
- What mechanical work needs to be done to continue the operation?
Today, the information to answer these questions can often be found in the automation system as well as from the operators in the test field. The need to provide transparent (management) information was the main requirement in the development of the newly developed FEVFlex. FEVFlex offers quick and safe access to the necessary information. Integrated interfaces to the TestCellManager (TCM) and external automation systems allow automatic documentation of the error status and control modes. Graphic display of activities (Fig. 1) as well as intuitive control elements allow the user to receive a quick overview. Quick reaction in cases of dysfunction at the test bench in necessary, so downtimes can be kept at minimum. Overview screens of the test bench state via signal lights signal an error status in the simplest manner in FEVFlex.
Furthermore, detailed statistical analysis of test bench operation is possible – supported by full-text search and subscription – to avoid systematic mistakes and associated selective investments. Based on this information, upcoming projects can be planned with regard to resources in FEVFlex. Therefore, necessary maintenance intervals of the used devices can be considered.
FEVFlex can be seamlessly integrated in the FEV product range, consisting of measurement technologies, automation system TCM/TOM, and our postprocessing system, FEVALYS (Fig. 2). The information to be used in FEVFlex serves as the link between automation and postprocessing. With this implementation, the circle between planning, measurement and analysis is completed.
