Abstract

Since a vehicle is prone to instability and rollover when taking a rapid turning, in this paper, an integrated control strategy of Electronic Stability Program (ESP for short) and active anti-roll steel bar (AARSB for short) is proposed. Then a three-degree-of-freedom vehicle dynamic model is established for rollover prevention and yaw stability control. In order to prevent the rollover and the instability of a vehicle, a linear quadratic (LQ for short) optimal controller is designed. The Particle Swarm Optimization (PSO for short) is adopted to optimize the weight coefficients of the LQ controller. Seven parameters are taken as the assessment criteria to carry out the simulation experiments on the vehicle with integrated control of AARSB and ESP in yaw stability and roll stability. These seven parameters are yaw rate, side-slip angle of mass center, roll angular velocity, roll angle, lateral load transfer ratio, additional yawing moment generated by ESP, and anti-roll moment generated by AARSB. To demonstrate the effects of the integration of AARSB and ESP on rollover prevention and instability control, two time typical simulations are conducted. The simulation results show that the vehicles with integrated control of AARSB and ESP can prevent the rollover and instability of a vehicle effectively. Therefore, with the integrated control, the driving stability of the vehicle is significantly improved.
