摘  要:基于车辆的运动学模型,研究了具有非完整约束特性的智能车辆弯路换道的轨迹跟踪控制问题。结合弯曲车道的曲率半径,针对换道过程中车辆横向运动和纵向运动对换道轨迹的耦合作用,提出了一种适用于弯道的换道轨迹规划方法。根据换道轨迹,利用积分反演法,引入中间虚拟控制量,设计了轨迹跟踪控制算法,并用Lyapunov稳定性理论证明了控制系统的稳定性。仿真结果表明:该控制器可以保证车辆在弯路换道的轨迹跟踪误差一致有界收敛,且具有快速、准确跟踪和全局稳定的特性。

The trajectory tracking control was studied for the lane changing of the intelligent vehicle with nonholonomic constraint feature on curved road based on the kinematics model of the vehicle. Considering the cuvacture radius of the lane and the coupling of the longitudinal and lateral movements with the lane changing trajectory in the lane changing process, a lane changing trajectory planning method suitable for the curved road was proposed. According to the lane changing trajectory, a tracking control algorithm was proposed using the integral backstepping with intermediate virtual controllers. The stability of the control system was proved by Lyapunov stability theory. The simulations were performed and the results demonstrated that the control system guaranteed the trajectory tracking errors of the vehicle lane changing on curved road were uniformly and above boundedly convergent. The tracking and robust global stability. control system is characterized by quick work precise
