Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to an energy-saving control method for automatic train driving. Background technique [0002] In recent years, rail transit and train control technology have developed rapidly, and the automatic train driving subsystem (ATO) has been widely used. In the field of urban rail transit, the ATO system has gradually become an important and necessary configuration. It is also used in some EMUs and high-speed rail lines. to the application. As an important part of the modern train control system, the ATO system, relying on the automatic train control realized by it, can reduce the manual labor intensity, accurately adjust the running time according to the real-time operation plan, improve the comfort of train operation, and greatly improve the operation efficiency of rail transit. [0003] With the rapid growth of rail transit operating mileage and the wide application of ATO systems,...

Problems solved by technology

But the defect of this scheme is: 1) in order to realize the maintenance of cruising speed, ATO system needs to control train traction and braking in real time, when the tolerance of speed fluctuation range is small, it is easy to switch traction and braking commands repeatedly, reducing ride Comfort; when the tolerance of the speed fluctuation range is large, it is easy to cause the train to be early or late

2) The repeated switching of the traction and braking commands of the ATO system during the cruising process is essentially unnecessary traction energy consumption. In the section with complex slope slopes, the acceleration and deceleration gains caused by the uphill and downhill make the traction caused by this control method The waste of energy consumption is more obvious

3) In the high-speed railway, due to the obvious increase of air resistance at high speed, the waste of traction energy consumption caused by the switching operation of traction and brake performed by the ATO system to maintain the cruising speed at high speed is more obvious
