A train position detection apparatus is configured to detect a position of a train by receiving positioning radio waves from satellites through a reception antenna. The train position detection apparatus includes: a memory that stores therein in advance a railway design standard of a railway track on which the train travels; and one or more hardware processors that detect a position of the train by self-contained navigation based on an input signal from a self-contained navigation sensor. When a result of the train position detection based on the positioning radio waves does not satisfy the railway design standard, the one or more hardware processors correct the result of the train position detection based on the positioning radio waves with a result of the position detection by self-contained navigation.

Train position detection apparatus and method

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.

Train control device

A train control device, according to one embodiment, includes a storage unit, an acquiring unit, and a control unit. The storage unit is configured to store therein information of a plurality of limit speeds corresponding to a plurality of respective blocks and being determined based on a block on which a preceding train traveling at least one ahead is located. The acquiring unit is configured to acquire schedule information of the preceding train indicating a time at which the preceding train exits each of the blocks. The control unit is configured to determine a limit speed in each of the blocks associated with a travel of a train, based on the acquired schedule information and the information of the limit speeds; and to create a travel plan of the train using the determined limit speed.

According to an embodiment, a train control device includes an acceleration detection unit and a train control unit. The acceleration detection unit detects acceleration of a train along a rotation radius direction, when the train is turning and passing a curved section of a rail line with a cant. The train control unit sets a passing speed of the train passing through the curved section so that a state of the train is placed in a balanced cant, based on a direction of the detected acceleration.
