The automotive industry is becoming increasingly complex with the integration of advanced technologies such as electric vehicles, fuel cell vehicles, and autonomous driving functions. To ensure that these systems operate correctly and safely, rigorous and accurate testing is essential throughout all stages of development. Hardware-in-the-Loop (HIL) technology plays a crucial role in meeting this demand by providing an effective real-time method for testing and validating control systems. In the automotive context, vehicle control systems, such as engine control units or propulsion systems, are integrated with simulated models of the rest of the vehicle and its operational environment. This approach allows for testing and validating control systems in a safe and controlled environment, reducing the need for expensive and potentially hazardous initial physical tests.
