摘要: 针对自动驾驶车辆在起伏弯道中的纵横向耦合稳定性控制策略开展研究,基于模型预测控制(Model Predictive Control,MPC)和自抗扰控制(Active Disturbance Rejection Control,ADRC)设计了耦合控制器,建立了纵、横向车辆动力学模型,设计了基于自抗扰控制的纵向控制策略和基于模型预测控制的横向控制策略,提出了纵横向耦合控制策略,构建了硬件在环(Hardware In the Loop,HIL)测试平台进行有效性验证。HIL仿真测试结果表明,耦合控制器与传统控制器相比,最大横向误差从0.48 m减小到0.16 m,平均绝对误差和平均误差都相对减小。所设计的耦合控制器能够将起伏弯道中的最大跟踪误差降低到0.33 m,并相对降低平均绝对误差和平均误差,能够有效保证高速自动驾驶车辆行驶的安全性和稳定性,避免滑移失稳等危险工况的发生。

Abstract: It investigates the integrated longitudinal and lateral stability control strategy for autonomous vehicles negotiating undulating curved roads. Based on Model Predictive Control (MPC) and Active Disturbance Rejection Control (ADRC), a coupled controller is designed. Longitudinal and lateral vehicle dynamics models are established. A longitudinal control strategy based on ADRC and a lateral control strategy based on MPC are devised. An integrated longitudinal and lateral coupling control strategy is proposed. A Hardware In the Loop (HIL) test platform is constructed for validation of the effectiveness. The results indicate that the coupled control reduce the maximum lateral error from 0.48 m to 0.16 m, and both the mean absolute error and the mean error are relatively reduced. The designed coupled controller can reduce the maximum tracking error in undulating curves to 0.33 m and relatively reduce the mean absolute error and the mean error, effectively ensuring the safety and stability of high-speed autonomous vehicles and preventing dangerous conditions such as sideslip instability.

Key words: autonomous vehicles, path tracking, speed tracking, Model Predictive Control (MPC), stability control
