Testing electronic control units at a mechanical level
ECUs that cannot be accessed by means of their electrical interfaces can be tested with the highly dynamic dSPACE test benches. The turn-key solutions can be optimally adapted to your specific requirements, letting you use mechanical loads and physically stimulated ECUs for testing.
Challenges
If an electronic control unit (ECU) cannot be accessed by its electric interfaces for hardware-in-the-loop (HIL) simulation, it has to be stimulated by another physical signal. This is often the case when it comes to testing complex mechatronic systems in vehicle dynamics applications, such as steering and braking. To achieve a realistic behavior of the components to be tested, HIL simulation at mechanical power level requires a test bench that uses real parts, such as an electric motor or mechanical loads that match those in the real vehicle. Mechatronic test benches stimulate the ECU sensors and actuators with physical signals.

dSPACE offers turn-key system solutions that are optimally adapted to your specific needs and allow for closed-loop tests also at a mechanical level. At dSPACE, you get all the components you need from a single source. The mechatronic test benches allow for the evaluation of complex systems in real time, 24 hours a day, 7 days a week. dSPACE’s hardware offers the required scalability, real-time performance, I/O interfaces, and a powerful tool chain to control a complete test bench from Simulink®. Moreover, one test bench characteristic stands out in particular: dynamics. Our customers often report that dSPACE test benches surpass their expectations regarding control dynamics and accuracy.
Choose a mechatronic test bench from dSPACE and benefit from the numerous strengths our systems have to offer, such as:
- Outstanding real-time behavior (latency, jitter, synchronization even for multiprocessor systems)
