N2 - Current and future motor vehicles are incorporating more and more sophisticated chassis control systems to improve vehicle handling, stability and comfort. These control systems often operate independently and thus interactions and performance conflicts among the control systems occur inevitably. To address the problem, this study proposes a two-layer hierarchical control architecture for integrated control of electric power steering (EPS) system and anti-lock brake system (ABS). The upper layer controller is designed to coordinate the interactions between the EPS system and the ABS. While in the lower layer, the two controllers including the EPS system and the ABS, are designed independently to achieve their local control objectives. Simulation results show that the proposed hierarchical control system is able to improve the vehicle lateral stability, and at the same time ensure the vehicle steering agility, and the braking performance.
