Lateral Stability Control for Heavy-Duty Vehicles Under Extreme Operation Conditions

This paper proposes a lateral stability control strategy for heavy-duty vehicles after a tire blowout with explicit consideration of vertical load redistribution, subject to multiple constraints, uncertainty and redundant actuation. Firstly, a parameterized wheel vertical load calculator is formulated to capture the dynamic characteristics, and the entire vehicle dynamic analysis is performed. Secondly, to attenuate the deviation from the reference path, a lane keeping controller is designed to enhance vehicle stability performance and original lane keeping capacity. After that, a reconfigurable constrained weighting least squares-based torque distributor is employed to accomplish the tracking of the virtual resultant yaw moment and longitudinal tire force. Simulations under different tire blowout conditions are conducted on the developed dynamic co-simulation platform to demonstrate the effectiveness of the designed control methods; furthermore, the influence of different tire blowout conditions on the vehicle movement behaviors is discussed. Statistical results based on the system lane keeping performance and control effort metrics highlight the superiority of the developed control strategy and approaches.
