Today, vehicles include various complex subsystems that are controlled through a Telematic Control Unit (TCU). Jointly evaluating these subsystems and TCU functional performance on the final product is the idea test. But it incurs significant test overhead coupled with the challenge of needing to evaluate a significant portion of use case scenarios. It also carries a significant risk of unpredictable testing costs and time-to-market delays.
Engineers have an alternative to help with these challenges - Hardware In the Loop (HIL) testing can pair simulation SW, network simulators, and TCU hardware together for test plans that include fault insertion and the ability to test real-world scenarios. Using a cellular network simulator combined with a 3rd party HIL test platform makes testing much easier and more thorough as you can control the TCU interactions and parameters of the network for different test cases.
