Robust yaw stability control of hybrid electric vehicles

Abstract

Yaw stability of an automotive vehicle in a various maneuvers is critical to the overall safety of the vehicle. Robust yaw stability control for a Through-the-Road Hybrid Electric Vehicle (TtR-HEV) with two in–wheel–motors in rear wheels is proposed using a Model Predictive control (MPC) controller. The propose technique aimed to enhance the yaw stability of TtR-HEV, especially on slippery roads to prevent vehicle from spinning out and provide safety driving under wide range of driving. This technique based on developed mathematical models of vehicle and tires. A Model Predictive control (MPC) controller applied to make vehicle yaw rate to track its reference. The control performance of the proposed yaw stability control system verified through computer simulation using MATLAB/SIMULINK. The yaw stability enhanced against uncertainties model, disturbances, and parameter variations. In addition, better performance achieved by applying the robust control that is satisfied high effectiveness and robustness.
