Track follow control method for rubber wheel low-floor intelligent rail train

Abstract

The invention discloses a track follow control method for a rubber wheel low-floor intelligent rail train. In the preceding process of the rubber wheel low-floor intelligent rail train, it is ensured that the central point of a first axle of the train and the central points of all hinged discs are operated on the same track; the turn angle in order to ensure that all wheels are operated on the same track in the proceeding process of the train is calculated in real time so as to control steering of a turn angle driving steering system in real time. The track follow control method has the advantages that control is more accurate, the turning radius can be reduced, and the driving flexibility can be improved.

Description

technical field [0001] The invention mainly relates to the field of urban public transport equipment, in particular to a train track following control method suitable for rubber-tyred low-floor intelligent rail trains. Background technique [0002] Urban rail transit refers to a special-line public transportation system with continuous guiding capabilities, which is characterized by having a specific track and vehicles running along the track. Common urban rail transit includes subways, light rails, and trams. Among them, subways and light rails are mostly built underground or on viaducts, and they can run freely in special rail lines by using the blocking mode. Although they have a strong transportation capacity, the initial infrastructure and vehicle purchase costs are relatively high, making them unavailable in small and medium-sized cities. application. Trams require a special power system and track coordination design, whether the design and construction costs or main...

Problems solved by technology

Although the passenger car of the articulated car train has a large passenger capacity, the biggest difference between it and the single passenger car is the change of the road passability caused by the lengthening of the body, which is specifically manifested in the increase of the turning radius and the increase of the lane area occupied by the turn. Large, it is easy to interfere with other elements of the road traffic next to it, so that it cannot pass smoothly, or even worsen the traffic operating environment, and it is impossible to realize public transportation quickly and efficiently
