STEERING CONTROL DEVICE FOR TRACKLESS TRAIN AND CONTROL METHOD THEREFOR

摘要

Disclosed is a steering control method for a trackless train, relating to the field of public transportation. The trackless train is formed of a locomotive 1 hinged to carriages of N trailers 2. The locomotive of the trackless train is provided with an axle for a pair of steering drive wheels 6. The steering drive wheels and steering angles thereof are controlled by a driver through a bogie 3. The bogie is provided with an angle sensor 9 connected to an input end of a steering angle meter 8. The kth trailer carriage is provided with a steering wheel 11 having a steering mechanism 10, wherein the steering angle of the steering wheel is controlled by the steering mechanism. A controller 7 is provided at the locomotive, wherein an input end of the controller is connected to an output end of a clock 4, an odometer 5 and the steering angle meter, and an output end of the controller is connected to an input end of the steering mechanism of each one of the trailers via an optical network 12. The controller simultaneously records a time t(s) output by the clock, a mileage(m) output by the odometer and a steering angle of the steering drive wheels of the locomotive output by the steering angle meter, and can then fully describe and control a travelling track of the trackless train, such that the steering wheels of the trailer carriages and the steering drive wheels of the locomotives maintain the same track during travel. The present invention is mainly applied to trackless public transportation systems.
