The embodiment of the invention provides a distributed power train traction brake control method and device, and the method comprises the steps: obtaining the target acceleration of a train accordingto the current running speed of the train and a preset target speed; calculating a target traction force or a target braking force of each bullet train carriage based on a multi-mass-point kinetic equation according to the total mass, the running resistance and the inter-vehicle coupling force of each bullet train carriage in the train and the target acceleration of the train; and controlling eachbullet train carriage according to the target traction force or the target braking force of each bullet train carriage. According to the embodiment of the invention, the performance difference of each bullet train carriage in the train is fully considered, the inter-vehicle coupling force of each carriage is effectively reduced, the train stably runs, the mechanical life of the train is prolonged, and the comfort level of the train is improved.
Description
technical field [0001] The invention relates to the technical field of train control, in particular to a traction braking control method and device for a distributed power train. Background technique [0002] EMUs or subway trains are composed of motor vehicles with fixed formation and trailers without power, and have the advantages of fast acceleration, light axle load, easy handling and high safety. Trains have gradually become the mainstream and future development direction of modern rail vehicles. With the increase of the running speed of the EMU, the characteristics of nonlinearity and strong coupling among the power units are obviously enhanced. [0003] The current driving mode based on the V-S (velocity-distance) curve is difficult to meet the safety, comfort, stability and energy-saving requirements of multi-group trains. If the distribution of the traction force or braking force of each power unit of the train is unreasonable, the longitudinal impact of the train...
