The invention provides a train tractive force determination method and a train control system. The method comprises the following steps: acquiring at least one ramp message, wherein at least one rampmessage comprises a ramp message corresponding to one carriage of a train; and determining a target tractive force of the train according to at least one ramp message. The train tractive force determination method and the train control system which are provided by the invention have the advantages that the determined target tractive force is more accurate, safety and comfort of the train are improved, for example, the target tractive force determined by the train by adopting the method provided by the invention can avoid potential safety hazard such as car sliding due to too small tractive force on an upslope line with large slope and can also avoid impact on passengers due to too large tractive force.
Description
Technical field [0001] The invention relates to the technical field of train network control, in particular to a method for determining train traction and a train control system. Background technique [0002] During the operation of the train, it is necessary to frequently start, run speed control and stop. The safety and stability of start, running speed control and stop is an important indicator of train performance. When the train stops, it is necessary to apply a holding braking force to prevent the train from slipping due to various reasons. This kind of holding braking force is a fixed value. In order to ensure that the train can stop stably on the line with the largest slope, the holding braking force is generally set to be larger. When the train starts, it is necessary to apply a target traction force so that the brake is relieved and the train starts normally; during the train operation, it is also necessary to apply a target traction force to make the train run at a pr...
