A test engineer is analyzing MiL results for a brake-by-wire model. The model's braking force output matches the reference for most test cases, but deviates significantly in a few. The deviations are within the tolerance defined in the requirements. What is the best course of action?

Modify the model to eliminate the deviations

Investigate the cause of the deviations even though they are within tolerance

Ignore the deviations and report the test as passed

Accept the deviations as within tolerance and document the results

A test engineer is analyzing MiL results for a stability control model. The model's yaw rate output matches the reference for most test cases, but deviates significantly in a few. What is the best way to determine if these deviations are acceptable?

Compare the deviations against the tolerance defined in the requirements

Run the same test multiple times to see if the deviations are consistent

Change the model parameters to reduce the deviations

Assume the deviations are due to simulation noise and ignore them

After running a MiL test for a lane-keeping assist model, the test engineer has a large dataset of simulation results. To evaluate the model's performance across all test cases, which approach is most effective?

Manually inspect each simulation plot

Calculate the average execution time of all simulations

Automate the comparison of key output signals against expected values for each test case

Only review the test cases that failed to compile

What is the main purpose of analyzing MiL test results?

To validate the mechanical stress on the vehicle chassis

To measure the electromagnetic compatibility of the ECU

To determine the fuel consumption of the vehicle

To evaluate the correctness and performance of the model under test

A team is setting up a MiL environment for a vehicle dynamics model. They need to simulate various road conditions and driver inputs. Which combination of components is essential for this MiL test environment?

A real-time simulator, a steering wheel, and a brake pedal

A target processor, a CAN interface, and a power supply

A simulation platform, the vehicle dynamics model, and a test harness for stimulus and measurement

A code generator, a compiler, and a debugger

Model in the Loop (MiL) CT-AUT Practice Questions (Page 1)

Part of the Testing in a virtual environment domain, which makes up ~27% of our current practice bank. ISTQB does not publish an official question count, but from its 60-minute exam (~25–40 total, ~7–11 in this domain), expect 1–2 from this objective — we provide 25 practice questions to prepare you well beyond it.
