A tyre blow-out can greatly affect vehicle stability and cause serious accidents. In the literature, however, studies on comprehensive three-dimensional vehicle dynamics modelling and stability control strategies in the event of a sudden tyre blow-out are seriously lacking. In this study, a comprehensive 14 degrees-of-freedom (DOF) vehicle dynamics model is first proposed to describe the vehicle yaw-plane and roll-plane dynamics performance after a tyre blow-out. Then, based on the proposed 14 DOF dynamics model, an integrated control framework for a combined yaw plane and roll-plane stability control is presented. This integrated control framework consists of a vehicle state predictor, an upper-level control mode supervisor and a lower-level 14 DOF model predictive controller (MPC). The state predictor is designed to predict the vehicle's future states, and the upper-level control mode supervisor can use these future states to determine a suitable control mode. After that, based on the selected control mode, the lower-level MPC can control the individual driving actuator to achieve the combined yaw plane and roll plane control. Finally, a series of simulation tests are conducted to verify the effectiveness of the proposed control strategy.
轮胎爆胎会极大地影响车辆稳定性并导致严重事故。然而,在文献中,对于突发轮胎爆胎事件的综合三维车辆动力学建模和稳定性控制策略的研究还很缺乏。在本研究中,首先提出了一个综合的 14 自由度(DOF)车辆动力学模型,用于描述轮胎爆胎后车辆的横摆面和侧滚面动力学性能。然后,基于所提出的 14 DOF 动力学模型,提出了一个用于横摆面和侧滚面综合稳定性控制的综合控制框架。该综合控制框架包括车辆状态预测器、上层控制模式监督器和下层 14 DOF 模型预测控制器(MPC)。状态预测器用于预测车辆的未来状态,上层控制模式监督器可以使用这些未来状态来确定合适的控制模式。之后,根据所选的控制模式,下层 MPC 可以控制各个驱动执行器来实现横摆面和侧滚面的综合控制。最后,进行了一系列仿真测试以验证所提出控制策略的有效性。
