摘　　要：针对无人驾驶地铁列车防空转防滑行问题,充分利用无人驾驶条件下的控车信息与控车方案,从列车底层控制、单列车最佳干预和多列车协同调度3个层面讨论了无人驾驶地铁列车防空转防滑行的关键技术和解决方案。列车底层控制在基于轮轨黏着特性和辨识方法基础上,分析了几种典型防空转防滑行的控制策略,单列车最佳干预提出了基于当前轮轨黏着状态下实现动力再分配的策略,多列车协同调度则利用线路信息和控车策略对全线路列车进行运营策略再调整。通过方案讨论,在基于列车底层控制的基础上,可使单列车获得最佳黏着利用,全线路列车获得最佳运营效能,并为无人驾驶列车的防空转防滑行设计提供参考。Aiming at the problem of anti-slip and anti-slide of driverless metro train,by fully utilizing the driverless vehicle-controlled information and scheme,the key technologies and solutions of anti-slip and slide were discussed from three levels of train bottom control,single train optimal intervention and multi-train collaborative scheduling.Based on the characteristics and its identification methods of wheel-rail adhesion,several typical control strategies of anti-slip and slide of train bottom control were analyzed.With the optimal intervention to the single train,a strategy of power redistribution based on the current wheel-rail adhesion state was proposed.By making use of line information and vehicle control strategy,the operation strategy of all the trains on the line was readjusted.Through the discussion of the scheme,the optimal adhesion utilization could be obtained for the single train based on the bottom control of the train,and the optimal operating efficiency could be obtained for all the trains on the line,which provided a reference for the design of anti-slip&slide of driverless metro train.
