Hydraulic brake system modeling and control for active control of vehicle dynamics

Active control of vehicle dynamics has become one of the top competitive features in today's automobiles. Vehicle dynamic control systems include antilock brakes, traction control and yaw control. The realization of these systems relies on the control of hydraulic brakes as well as other vehicle systems. Modeling of the hydraulic brake system is essential to the design of vehicle dynamic control systems. The paper describes the derivation of a hydraulic brake system model using the bond graph technique, and the design of a feedback control system with an adaptive gain schedule PD controller. In addition, simulation and experimental results are presented to illustrate the model validation and the controller performance.
