HIL system for steering controller tests

Yaw stability control is an important consideration in active safety of road transport. As steer by wire systems are now commercially available, steering actuated yaw stability controllers are expected to become more significant. The steer by wire actuator bandwidth and saturation limits may set achievable performance constraints on such steering controllers. This paper focuses on hardware in the loop (HIL) testing of steering controllers to investigate such performance problems. A HIL steering controller test setup is presented in this paper for that purpose.
