考虑旁车切入的车辆自适应巡航控制策略研究

Research on Adaptive Cruise Control Strategy Considering for a Vehicle Under a Side Vehicle Cutting in

为了兼顾安全性和舒适性,开展切入工况的自适应巡航控制优化研究。本文以车辆速度差最小化作为控制目标,利用反馈控制理论优化ACC策略,以保持平稳跟随前车的运动状态。优化后的ACC策略应用表明,在旁车切入下,主车可以保持设定的安全距离,且加速度变化保持在10%左右。

To give attention to safety and comfort,the authors carry out the research on adaptive cruise con-trol optimization under cut-in conditions.They take the vehicle speed difference minimization as the control objective,and use feedback control theory to optimize the ACC strategy to maintain a motion state while smoothly following the preceding vehicle.The application of the optimized ACC strategy shows that the main vehicle can maintain the set safe distance and maintain an acceleration change of about 10%.
