Automotive functional tests in an EMC environment

Verify end-to-end operation of vehicle features

Vehicle manufacturers are integrating increasingly advanced capabilities to realize automated driving, meet regulatory obligations and provide customers with new services and features. Most of these capabilities are enabled by wireless standards, such as 5G and UWB, and radar/lidar sensors.

The automotive industry requires a robust, repeatable and efficient test process to verify the end-to-end operation of vehicle functions such as emergency braking or 5G eCall. However, it is becoming increasingly impractical to conduct tests on proving grounds. This is due to the:

  • Time consumed
  • Required test resources
  • Measurement uncertainty associated with testing in an open-air environment

The solution is to migrate the tests to the lab. The precisely-controlled electromagnetic conditions provided by an EMC chamber is an ideal environment for functional tests - allowing for repeatable, resource-efficient measurements.

Your automotive functional testing challenges

The development of safe, reliable vehicles comes with many challenges. There are many complexities - from integrating sophisticated electronic and mechanical components to ensuring the secure operation of interconnected features.

  • Verifying correct operation and performance of automotive features at vehicle level prior to mass production
  • Checking the safe and secure operation of vehicle features
  • Ensuring consistency and repeatability of test processes and results
  • Maximizing utilization of test resources (people, equipment, time)
  • Reducing field test costs
