HIL Research of Vehicle Stability Control Algorithm Based on veDYNA

The hardware-in-the-loop (HIL) test rig was designed for the study and development of a vehicle stability control system based on the veDYNA software platform and xPC Target technology. The real-time vehicle dynamics model was established and verified by experimental data, and the vehicle stability control algorithm based on slip was designed and embedded in the vehicle real-time dynamic model. By using the hardware-in-the-loop test rig, the steering wheel incremental trapezoid input test was performed under high adhesion, and the steering wheel sinusoidal input test was performed under low adhesion. The results show that the developed hardware-in-the-loop test rig meets the requirements of simulation and the designed control algorithm can improve vehicle handling and stability effectively.
