Robust Stability Analysis

The rollover accidents induced by severe maneuvers are very dangerous and mostly happen to vehicles with elevated center of gravity, such as heavy-duty trucks and pickup trucks. Unfortunately, it is hard for drivers of those vehicles to predict and prevent the trend of the maneuver-induced (untripped) rollover ahead of time. In this study, a lateral load transfer ratio which reflects the load distribution of left and right tires is used to indicate the rollover criticality. An antiroll controller is designed with smooth sliding mode control technique for vehicles, in which an active antiroll suspension is installed. A simplified second order roll dynamic model with additive sector bounded uncertainties is used for control design, followed by robust stability analysis. Combined with the vehicle dynamics simulation package TruckSim, MATLAB/Simulink is used for simulating experiment. The results show that the applied controller can improve the roll stability under some typical steering maneuvers, such as Fishhook and J-turn. This direct antiroll control method could be more effective for untripped rollover prevention when driver deceleration or steering is too late. It could also be extended to handle tripped rollovers.

In this paper, the problem of vehicle yaw control using differential braking is investigated. The proposed control structure employs the wheel slip controller to apply differential braking to generate the yaw moment calculated by the yaw controller. A fuzzy logic based target slip allocation method is also designed. Due to system uncertainties and wide range operation conditions, two different yaw controller which are based on sliding-mode control and PID control are designed, and their performances are compared by hardware in loop simulation. The obtained results show the effectiveness of the proposed control structure with both yaw controllers, but the sliding mode based yaw controller can be more robust.
