The active braking control system is an active safety system designed to prevent accidents and to stabilize dynamic manoeuvers of a vehicle by generating an artificial yaw moment using differential braking forces. In this paper, the yaw-roll model of a single unit heavy vehicle is used for studying the active braking system by using the longitudinal braking force at each wheel. The grid-based LPV approach is used to synthesize the H∞/LPV controller by considering the parameter dependant weighting function for the lateral acceleration. The braking monitor designs are proposed to allow the active braking system to react when the normalized load transfer at the rear axle reaches the criteria of rollover ±1. The simulation results indicate that the active braking system satisfies the adaptation of vehicle rollover in an emergency situation, with low braking forces and improved handling performance of the vehicle.

Vehicle rollover is a very serious problem when considering the safety of heavy vehicles, which can result in large financial and environmental consequences. This paper investigates the interest of a Linear Parameter Varying (LPV) controller for an active anti-roll bar system of single unit heavy vehicles, in order to enhance roll stability. We propose a parameter dependent \(H∞/LPV\) controller with weighting functions, scheduled by the forward velocity (the varying parameter of the vehicle LPV model) and by the normalized load transfers at the two axles (part of the parameter dependent weighting functions) providing an on-line performance adaptation to the vehicle rollover risk. The effectiveness of the proposed controller is validated by using the TruckSim® simulation software with two different types of heavy vehicle: a fully loaded bus and a truck. The simulation results, in the frequency and time domains, show that the proposed strategy drastically improves the vehicle roll stability when compared with a \(H∞/LTI\) controller, a fixed weighting functions \(H∞/LPV\) controller and a passive anti-roll bar system.

Today there are over 1.3 billion vehicles in use all over the world and vehicle rollover is a serious safety problem, which can result in large financial and environmental consequences. In order to improve the roll stability, most modern vehicles are equipped with the passive anti-roll bar system to reduce roll motion during cornering or riding on uneven roads. However, the passive anti-roll bar does not meet the required stability when the vehicle is in an emergency. This paper introduces the active anti-roll bar control which is designed by finding an optimal control, based on a Linear Quadratic Regulator (LQR). A four-degree-of-freedom half roll model that captures the essential vehicle dynamics associated with rollover phenomenon is presented. The obtained results of comparison of performance between a passive and an LQR active anti-roll bar show the significant effectiveness of the active anti-roll bar control in various maneuver situations.
