Abstract: The complexity of automobiles has increased tremendously in this decade to address environmental issues, customers' sophisticated demands and safety. Electric Vehicles (EV) and Autonomous Vehicles (AV) have a lot of new cutting-edge technologies that have been incorporated into them. EVs and AVs rely on a combination of cameras, sensors and artificial intelligence algorithms for navigation and decision-making on the road. This development in EV and AV subsystems requires a platform to test and validate the developed systems effectively and safely. Hardware in the Loop (HIL) is one of the solutions used to validate the models or prototypes developed in the latest automotive systems. HIL can closely mimic the actual plant model and is used to evaluate the automotive control system before building it into a real-time system. HIL testing adaptation for the autonomous platforms from SAE level 0 vehicles to SAE level 4 vehicles, such as Drivability development and Regenerative Brake by Wire, Longitudinal and Lateral automation, are elaborated in this review. This paper concludes that the HIL testing platform helps the researchers validate the developed subsystems before the prototype or manufacturing of a vehicle, increases safety and reduces development time and cost.

Keywords: vehicle safety; hardware-in-the-loop; automotive control systems testing and validation.
