摘要: 针对智能车辆在换道过程中存在的安全性问题, 提出了智能网联汽车的安全自主换道模型. 在两车道的换道场景下,基于车车通信技术得到换道车辆及周围车辆的运动状态信息, 借助博弈论建立换道车辆与周围车辆的协同换道决策模型, 得到允许换道指令信息后, 基于模型预测理论设计了换道轨迹跟踪控制器. 通过仿真, 对比其他研究模型, 定量分析验证所建模型和设计的轨迹跟踪控制器具有良好效果, 实现了智能车辆安全准确的自主换道.Abstract: Aiming at safety problems of intelligent vehicles during lane-changing, a safe autonomous lane-changing model of intelligent networked vehicles is proposed. In the two-lane scenario, based on the vehicle-to-vehicle communication technology, the motion state information of the lane-changing vehicle and surrounding vehicles is obtained. The cooperative lane-changing decision model is established by game theory. Based on Model Prediction Control (MPC) theory, lane-changing trajectory tracking controller is designed. Through simulation, compared with the current research methods, the quantitative analysis verifies that the designed trajectory trackingcontroller realizes the safe and accurate lane-changing of the intelligent vehicle.
