Abstract: 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.

Abstract: A railroad track recognition apparatus has an index calculating unit, an initial searching unit, a secondary searching unit, and a railroad track recognizing unit. The index calculating unit calculates an index value, for each pixel or pixel group of a captured image. The initial searching unit selects a line segment, having a larger evaluation value obtained from the index values, from a plurality of line segments in a first search area, and the secondary searching unit selects a line segment, having a larger evaluation value obtained from the index values, from a second area or a third area. The railroad track recognizing unit recognizes a railroad track based on reference points of the line segments selected by the initial and secondary searching units.

Abstract: A running profile generation device includes a storage, a speed limit setter, a reverse coasting curve generator, a parameter setter and a simulator. The speed limit setter acquires at least one speed limit section of a running section set based on a departure point and an arrival point of the running section. The reverse coasting curve generator determines a base point from a terminal position and an upper limit speed of the speed limit section and generates a reverse coasting curve based on vehicle performance information and route information stored in the storage. The parameter setter determines a coasting start position from the generated reverse coasting curve. The reverse coasting curve generator sets a range below the upper limit speed as a coasting range and sets a range at at least the upper limit speed to the upper limit speed during coasting from the base point toward the departure point.
