## Abstract

A train control device includes a train position detector, a storage, and an in-vehicle controller. The train position detector detects a traveling position of a train. The storage stores therein a traveling position of the train when a loss of contact of the current collector occurs, as a loss-of-contact position. 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 in-vehicle controller causes the train to perform coasting traveling in the predetermined section.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The train control device according to claim 1, further comprising:
a communication unit that communicates with a ground control device, wherein
the in-vehicle controller informs the ground control device of the detected loss-of-contact position,
the ground control device stores the loss-of-contact position, collects data on the loss-of-contact position, and informs the in-vehicle controller of the collected data, and
the in-vehicle controller performs control of the coasting traveling based on the collected data.
