Stationary and mobile testing go hand in hand in the development of modern automotive technology. Up to now, the conversion of the test vehicle was a significant obstacle when changing between mobile and stationary testing.
The aim was to implement a modern data logger system that combines the requirements of mobile and stationary testing.
All devices in the vehicle are networked via a CAN bus. A central measurement logger (imc CRONOS-PL) collects all measurement data on a PCMCIA removable disk. The different device configurations are selected via a manual control unit.
On the test bench
In contrast to use in the vehicle, the requirement for the test bench or climatic chamber/ wind tunnel measurement logger is that the instrumented vehicle remains unaltered in its connection with the test stand via Ethernet. No more instrumentation - the vehicle remains as it was equipped for the test drive. All connected measurement channels can now be visualized and stored directly on the connected PC.
