Preventing rollover phenomenon with an active anti-roll bar system using electro-hydraulic actuators: A full car model

This paper discusses the role of active anti-roll bar system in order to enhance roll stability cars, thereby preventing rollover phenomenon high speed emergency situations. First, an integrated full car model is proposed including longitudinal, lateral, vertical motions and electro-hydraulic actuator model. In this model, control signal being input current which supplied actuators create torques improve car's stability. most general theory study a big step forward compared previous related studies. The optimal LQR method has then been used synthesize controller based on with 26 degrees freedom. criteria assess vehicle are sprung mass angle interactive force between wheels road surface. simulation results frequency domain validation time through CarSim software's nonlinear clearly show advantages rollover.
