AVL and R&S Develop Solution for Automated EMC Data Analysis of Vehicles Under Real Driving Conditions
AVL and Rohde & Schwarz have developed an innovative solution for automated electromagnetic compatibility (EMC) data analysis of an electric drive-train under real driving conditions. This solution is designed to ease and speed up the development process of EMC testing of vehicles while keeping the test conditions as realistic as possible. It also enables dynamic testing of vehicles where the drivetrain is active, varying in speed as well as torque during the execution of the EMC test.
The real-time synchronization of measurement data between the EMC testbed, measurement system, and automation software is key to efficient and repeatable EMC-compliant components and vehicle development. AVL and R&S’ test solution supports automated testing with the simulation of real driving scenarios while covering typical automotive standards at the same time. The AVL PUMA 2 automation controls the test cycle and stores the measured data, in synchronization with the R&S ELEKTRA EMC test software to exchange information between the testbed and the EMC measurement equipment. The ELEKTRA software has been modified to enable automatic and seamless communication with AVL CONCERTO software, replacing a previously manual process. CONCERTO is post-processing the measured data automatically and gives a full test report according to the pre-defined pass and fail criteria.
R&S ELEKTRA controls complete EMC systems and automates measurements of equipment under test (EUT) being certified for emissions (EMI) and immunity (EMS). The software simplifies the configuration of test systems and test descriptions in accordance with common standards. It speeds up test execution and paves the way to quickly generate a comprehensive test report.
“Many customers have been waiting for years to see Rohde & Schwarz EMC analyzers connected to the AVL EMC test automation system. Together, we have finally accomplished this, and are pleased to offer this new solution, improving and accelerating EMC validation of e-drives and vehicles,” states Alban Hemery, Department Manager for E-Motor Test Systems and EMC Applications at AVL List GmbH.
“As market leader in EMC instrumentation, Rohde & Schwarz has a long and productive history of collaboration with AVL to develop leading-edge test systems for the automotive industry. The enhancement of R&S ELEKTRA to be compatible with AVL’s PUMA 2 is another significant step speeding up EMC test times under real driving conditions, particularly for electric drivetrains,” adds Juergen Meyer, Vice President, Market Segment Automotive at Rohde & Schwarz.
