Single-box, real-world interference impairment injection for connected car developers

April 12, 2016 // By Graham Prophet
Spirent Communications (Crawley, UK), as part of its connected car verification systems, has announced instrumentation to reduce the time and cost needed to develop automotive Ethernet BroadR-Reach systems for connected cars and other vehicles. Spirent test solution also helps auto makers create better infotainment and other advanced features.

As cars adopt automotive Ethernet to provide advanced driver assistance systems (ADAS), vehicle-to-X (V2X) communication, infotainment and other ‘connected car’ features, manufacturers need to ensure these networks are unaffected by electromagnetic interference normally found in vehicles.

 

The Spirent AING-5000 reduces the time to develop systems that are resilient to interference, by creating and customizing a variety of real automotive noise conditions, which developers can use repeatedly to optimize their designs.

 

The AING-5000 creates continuous background noise, electro-mechanical switching-impulsive events, and other radio-frequency interference (RFI). These noise conditions/types are problematic and testing electronic control units (ECUs) against these real world conditions has become a necessity for systems development. It can also be very costly and time consuming if a physical electro-magnetic compatibility (EMC) chamber is the only verification tool available.

 

The Spirent AING-5000 comes pre-packaged with a set of baseline real world measured noise events specifically designed to test Automotive BroadR-Reach Ethernet. These can also be adjusted by the user to create specific interference signals. It also offers a high impedance unit for injecting noise into two-wire automotive cabling.

 

The AING-5000 joins a portfolio of Spirent tools that help the automotive industry to successfully develop self-driving and connected car features and provide improved end user experience. This portfolio includes systems to help develop automotive Ethernet, V2X/telematics, Cybersecurity, vehicle positioning and navigation, and emergency services, such as eCall.
