Train control device

A train control device comprising:

• a train position detector that detects a traveling position of a train;
• a storage configured to store therein a traveling position of the train when a loss of contact of a current collector occurs, as a loss-of-contact position;
• an in-vehicle controller that causes, when the train travels in a predetermined section including the loss-of-contact position with reference to the traveling position of the train and the storage, the train to perform coasting traveling in the predetermined section;
• and
• a driving/braking controller that performs a driving and braking control of the train, and detects the loss of contact of the current collector, wherein
• the in-vehicle controller calculates a traveling plan to output a control command for controlling the driving/braking controller based on the traveling plan, and causes the storage to store therein the loss-of-contact position when the loss of contact of the current collector is detected by the driving/braking controller,
• the driving/braking controller includes an interruption detection unit that detects, via the current collector, an interruption of electric power supply from an overhead contact line, and
• the in-vehicle controller:
• makes a traveling plan for the train to accelerate or decelerate within an allowable capacity of a drive motor supplied with electric power from a current collector located at a contact position, with reference to the storage;
• and
• gives a coasting command to the chive motor supplied with electric power from the current collector located at the loss-of-contact position.
