   What is the primary purpose of data logging in HiL testing?

   • ATo generate the test report automatically
   • BTo record signals and events during the test for later analysis and debugging
   • CTo provide real-time feedback to the test engineer during the test
   • DTo control the simulation model

   Which of the following is an example of a fault that can be simulated in HiL testing?

   • AA sensor signal that is out of range (e.g., voltage above the maximum)
   • BA change in the plant model parameters
   • CA difference in the ECU's supply voltage due to battery aging
   • DA software bug in the test automation script

   A HiL test bench is being set up for a new ECU. The test team has a tight deadline and needs to start testing as soon as possible. The plant model is still under development, but a preliminary version is available. The team is considering using the preliminary model to start setting up the test environment. What is the most appropriate approach?

   • ASkip the plant model and use a signal generator to simulate sensor inputs.
   • BStart setting up the HiL environment with the preliminary model, but plan for model updates as the model matures.
   • CUse a simple placeholder model for initial setup, then replace it with the final model.
   • DWait until the plant model is fully validated before starting any HiL setup.

   What is a common approach to automating HiL tests?

   • ARunning the same test repeatedly without any changes
   • BUsing only hardware switches to simulate faults
   • CUsing test scripts that control the simulation, inject inputs, and evaluate ECU responses automatically
   • DHaving a test engineer manually adjust knobs and observe the ECU
