Abstract
The present invention relates to a train control device. The train control device sets an emergency brake pattern and a regular brake pattern as patterns of maximum speed according to the distance to a stopping point, and outputs a braking command when the train speed exceeds the maximum speed. Then, when the maximum speed defined in the regular brake pattern falls below a set speed, the maximum speed of the regular brake pattern is kept constant for a predetermined distance. After that, the maximum speed is gradually reduced toward a stopping point of the emergency brake pattern. This allows a train to make an approach to a fixed stopping position in an automatic train operation even when the fixed stopping position is located farther than a stopping point of the regular brake pattern, and excessive output of an emergency braking command based on the emergency brake pattern can be reduced.
