TÓM TẮT
Rollover of heavy vehicles is an important road safety problem world-wide. Several active control schemes have
been proposed to prevent rollover, such as active steering, active suspension, active anti-roll bars, with the active
braking system being the most common method used for vehicles. In this paper, the active braking system is
combined with the passive suspension system. The grid-based LPV approach is used to synthesize the H∞/LPV
controller which is self-scheduled by two varying parameters: the forward velocity and the normalized load
transfer at the rear axle. The parameter dependent weighting function for the lateral acceleration is used in order
to allow for the vehicle performance adaptation to the risk of rollover. Simulation results are performed in the
frequency domain, and emphasize the efficiency of the proposed methodology.
