摘要： A method and system for determining a ground speed for locomotives (e.g., 12, 14) of a train (16) comprising at least two locomotives for use in controlling an operation of the train. The method includes selecting an axle of any one locomotive of the train for measuring a speed corresponding to the selected axle. The method also includes determining a ground speed for at least another locomotive of the train based on a measured speed corresponding to the selected axle of the one locomotive.

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（A1-A6）的机车（V）的牵引力的方法，其中每个车轮（A1-A6）都安装有用于使机车在一组轨道（R）上移动的轮子（W）。向每个轴的控制器（TMTC）提供蠕变控制信号（蠕变_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而言是最大的，则将组合代表两个轴的附着质量的顾问信号（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。

摘要： A propulsion system for a relatively large land-based vehicle, such as a locomotive or off-highway vehicle, is provided. The system may include a brushless dynamoelectric machine made up of a main alternator having a main rotor and a main stator, and an auxiliary alternator having an auxiliary rotor and an auxiliary stator, wherein the main rotor and the auxiliary rotor are disposed on a shaft for joint rotation with the shaft. The dynamoelectric machine is operable in a power generating mode, and in an engine cranking mode. A power source may be connected to pass current to one or more windings in the auxiliary stator to induce an alternating current flow in one or more windings in the auxiliary rotor. A rectifier may be connected to receive the alternating current flow from the one or more windings in the auxiliary rotor. The rectifier is further connected to supply a rectified current to one or more windings in the main rotor to induce an alternating current flow in one or more windings in the main stator of the machine, wherein the alternating current flow in the one or more windings in the main stator of the machine constitutes the current generated by the dynamoelectric machine during the power generating mode. The power source to be connected during the engine cranking mode may be first and second inverters connected to provide an AC conversion to a DC input from an energy storage device to supply a respective alternating current having some desired characteristics. The one inverter may be connected to the one or more windings in the main stator, and the other inverter may be connected to the one or more windings in the auxiliary stator to produce a torque in the main rotor of the machine. The torque produced at the main rotor of the machine is mechanically coupled to a crankshaft of an internal combustion engine of the propulsion system to start the engine during the engine cranking mode.

摘要： A multi-level system for management of a railway system (50) and its operational components in which the railway system (50) has a first level configured to optimize an operation within the first level that includes first level operational parameters which define operational characteristics and data of the first level, and a second level configured to optimize an operation within the second level that includes second level operational parameters which define the operational characteristic and data of the second level. The first level provides the second level with the first level operational parameters, and the second level provides the first level with the second level operational parameters, such that optimizing the operation within the first level and optimizing the operation within the second level are each a function of optimizing a system optimization parameter. The levels can include a railroad infrastructure level (100), a track network level (200), a train level (300), a consist level (400) and a locomotive level (500).
