Automotive components are becoming more complex, with integrated and active control units as a standard part of the subsystem. Production testers must be able to configure and control these parts in addition to testing their functionality and performance.
CAN, LIN, and More
Signal.X has extensive experience supporting standard automotive bus protocols. This can range from importing a simple *.dbc file to acquire a few channels, to integrating CAN, LIN, SPI, SENT, and other low-level protocols as part of a test system, all synchronized to the analog data.
A Progression of Complexity
Electronic Control Units are at the heart of the movement to electrification. End-of-line test systems can interact with ECUs in a multitude of ways, including:
- vehicle cyber security standards
- extended seed/key programming sessions
- flashing the ECU
- reporting trouble and fault codes as part of the test sequence
STAX enables this level of interaction by allowing customized development in the form of threads. Threads are parallel code segments that support specialized purposes, and can be unique to a customer or project. Written in LabVIEW, they can leverage custom code, specific NI toolkits, and customer-specific intellectual property. When integrated into STAX, the complex interactions with an ECU can be abstracted to be understandable inside a standard test sequence.
An Integrated Approach
Our systems bring together high-speed analog data with all of the networked data sources (CAN, LIN, Ethernet) for a single synchronized data file that can be processed to pass/fail using our Shield platform. Close the loop around the data using Trove, and extract more value from the data collected in production.
