摘要： A control assembly includes a monitoring module and a switching module. The monitoring module determines a load demand of a first rail vehicle traveling along a track, wherein the first rail vehicle is supplied with electric current from a plurality of power sources over a conductive pathway extending along the track. The switching module is communicatively coupled with the monitoring module and is joined with a switch controller disposed between the power sources and the conductive pathway. The switching module directs the switch controller to change which of the power sources supply the electric current to the first rail vehicle over the conductive pathway based on the load demand.

摘要： A method of dynamically controlling traction of a locomotive (V) having a plurality of axles (A1–A6) on each of which are mounted wheels (W) for moving the locomotive over a set of rails (R). A creep control signal (creep_n) is provided to a controller (TMTC) for each axle to move the locomotive over the rails, the creep control signal being a function of adhesion operation characteristics (tractive effort, torque, creep) for that axle. An advisory signal (ccc_n) combining values representative of the adhesion quality of the two axles is provided to the controller to maximize the tractive effort of the axle if the adhesion quality of the other axle is a maximum for the current rail conditions. This reduces the amount of time for the axle to attain its maximum tractive effort when rail conditions change.
摘要翻译：一种动态地控制具有多个轴（A 1 -A 6）的机车（V）的牵引的方法，每个车轴（A 1〜6 6）安装有用于使机车在一组轨道（R）上移动的轮（W）。向每个轴的控制器（TMTC）提供蠕变控制信号（creep_n），以使机车在轨道上移动，蠕变控制信号是该轴的粘附操作特性（牵引力，扭矩，蠕变）的函数。如果两个轴的粘合质量的组合值对于当前轨道条件是最大的，则将组合两个轴的粘合质量的值的咨询信号（ccc_n）提供给控制器以使轴的牵引力最大化。这减少了当轨道条件改变时车轴达到最大牵引力的时间。
