Research on Rollover Prevention Stability of Heavy Truck Based on PID

According to the stability problem of the heavy truck, the anti-yaw moment control method based on PID is adopted, then the rollover dynamic model and the 2-DOF(two-degree-of-freedom) reference model for heavy truck are established. And a PID feedback control system is designed, it takes the deviation of the target yaw and actual yaw rate value as the control variable, and the anti-yaw moment is obtained to maintain the stability of the vehicle. Finally, the simulation model is built with matlab/simulink, the results of simulation show that the PID-based anti-yaw moment control method effectively improves the stability of heavy truck.
