6. Validation of the Active Anti-Roll Bar Control System by Using TruckSim^® Software

This chapter presents the validation of the \(H_{\infty }/LTI\) and \(H_{\infty }/LPV\) active anti-roll bar controllers proposed in Chaps. 4 and 5 by using the nonlinear vehicle model of \(\text{ TruckSim }\)^® software. Three co-simulation programs between Matlab/Simulink and TruckSim are built for three typical heavy vehicles: a tour bus, an LCF truck and a tractor semi-trailer in unloaded and fully loaded states. The main survey scenarios include: Double lane change to overtake, Circular test circuit, Cornering manoeuver, Sine wave steering manoeuver at the different velocities. The results examined with different scenarios and the different forward velocities have clearly shown the effectiveness of improving the roll stability of heavy vehicles. It also shows that the handling performance has improved when the heavy vehicles use the active anti-roll bar system. This is consistent with the results studied in the previous chapters.
