AI Technical Summary
Technical Problem
In existing technologies, the braking command continuously decelerates the train without requiring any changes, resulting in a worse riding experience when the train stops and potentially extending the travel time.
Method used
The train control system calculates the train's speed and position, predicts the difference between the deceleration and the target deceleration mode, adjusts the braking command to change the position deviation within the allowable range, suppresses frequent changes in braking command, and ensures passenger comfort.
Benefits of technology
Without extending travel time, reduce the frequency of braking command changes, improve passenger comfort when the train stops, and prevent a deterioration in the passenger experience.

Abstract
An object is to prevent deterioration of a ride at the time of stopping while suppressing an extension of travel time by attenuating a brake command at the time of stopping. A train control device of an embodiment has a train speed position detection device that detects a speed of a train and a position of the train, a storage section that stores route information and vehicle information, and a control command calculation section that calculates a control command to a drive brake control device based on the detected speed of the train and the position of the train and the route information and the vehicle information, and the control command calculation section changes a position deviation allowable range in a position direction according to a difference between a deceleration of a target deceleration pattern at a speed identical to a train speed prediction value after a prescribed time and the train deceleration prediction value after the prescribed time.
