Yaw Stability Control Based on a Novel Electronic Hydraulic Braking System

This paper presents a yaw stability control algorithm on basis of a novel electronic hydraulic braking system (EHBS) aiming to enhance the vehicle stability performance in handling control conditions. The operational principles of EHBS are introduced with the featured mechanical layout. Modeled in the multi-domain software AMESim and CarSim, a nonlinear vehicle dynamics and the EHBS models are demonstrated in detail. The proposed yaw stability control algorithm is structured as a hierarchical architecture, covered with the sliding mode control (SMC)-based yaw moment calculation, the rule-based brake allocation, and the hydraulic pressure modulation. The simulation is conducted according to the standard sine-with dwell maneuver. Simulation results show that the proposed yaw stability control algorithm with EHBS can effectively improve the vehicle stability performance under severe driving maneuvers.
