A vehicle includes running wheels traveling on traveling road surfaces of tracks; a pair of position detection parts disposed at an interval in a width direction that output signals by detecting a distance from measured objects; a control unit controlling the amount of steering of the running wheels according to the signals from the position detection parts; and a steering mechanism steering the running wheels via the control unit. Each of the position detection parts outputs a signal having characteristics such that the output increases as the distance from the measured objects increases while an output change ratio is decreased in a range wherein the distance from the measured objects is not less than a predetermined value, and is configured such that, when the distance between one position detection part and the measured object is decreased, the distance between the other position detection part and the measured object is increased.

A system includes a mobile platform that moves under remote and/or autonomous control, a sensor package supported by the mobile platform that obtains information relating to a component of a transportation network, and one or more processors that receive the sensor information and analyze the information in combination with other information that is not obtained from the sensor package. The processors also generate an output that displays information relating to one or more of a status, a condition, and/or a state of health of the component of the transportation network; initiates an action to change an operational state of the component; identifies a hazard to one or more vehicles traveling within the transportation network; and/or collects the information relating to the component. Optionally, the component is not communicatively coupled to an information network and the mobile platform provides the information obtained by the sensor package to the information network.

This position detection system is provided with: a distance measuring sensor that is attached to a vehicle traveling along a track and is capable of measuring a distance over a predetermined range in the track width direction; an edge position detecting unit that detects an edge position in the track width direction of the track on the basis of distance measurement data from the distance measuring sensor; and a distance calculation unit that calculates a distance in the track width direction between a reference position of the track that is specified from the edge position and a reference position of the vehicle to which the distance measuring sensor is attached.

There is provided an automatic train operation system which can stop a train precisely at a stop target position without worsening ride quality even with the control system being a discrete system. The automatic train operation system comprises a relative distance measuring device to acquire information about a relative distance of the train relative to a stop position of a station to output average distance information that is the average of relative distances and a brake control device. The brake control device includes a sensor information holding unit to hold speed information and position information detected by sensors to output; a correction amount computing unit to compute a specifying value correction amount to output; and an instruction planning unit to compute a deceleration specifying value based on the specifying value correction amount and sensor information.

A train control apparatus includes: a first ground device 22a provided in a first section CZ1; and a second ground device 22b provided in a second section CZ2 continuing from the first section CZ1 in a train travel direction. When a train 10 in the first section CZ1 enters a control transition section ZCR determined using a control section border CZI as a termination end, the first ground device 22a instructs a first vehicle radio set 14r to send a first report signal RR1 to the first ground device 22a in accordance with a first communication condition determined by the first ground device 22a, and instructs a second vehicle radio set 14f to send a second report signal RF2 to the second ground device 22b in accordance with a second communication condition determined by the second ground device 22b. In response to the reception of the second report signal RF2 from the second vehicle radio set 14f, the second ground device 22b instructs the second vehicle radio set 14f to send a report signal including train location information to the second ground device 22b in accordance with the second communication condition.

A system comprises a first sensor on a first end of a vehicle and an on-board controller coupled to the first sensor. The first sensor is configured to detect a radio frequency (RF) signature of a marker along a guideway. The first sensor is a radar detection device. The on-board controller is configured to determine a first position of the vehicle on the guideway or a first distance from the position of the vehicle to a stopping location along the guideway based on at least the RF signature received from the first sensor. The marker is a metasurface plate comprising a first diffused element, a first retroreflector element, a first absorbing element and a second diffused element between the first retroreflector element and the first absorbing element.

A vehicle has a detection device for detecting a route-side transmitter device. The detection device has at least two receiving antennas which are suitable for receiving a magnetic field component, oriented in a longitudinal direction of the vehicle, of electromagnetic radiation which is emitted by the route-side transmitter device. The at least two receiving antennas are arranged with an offset in the longitudinal direction of the vehicle.

A system for operating a train having one or more locomotive consists with each locomotive consist comprising one or more locomotives, the system including a locator element to determine a location of the train, a track characterization element to provide information about a track, a sensor for measuring an operating condition of the locomotive consist, a processor operable to receive information from the locator element, the track characterizing element, and the sensor, and an algorithm embodied within the processor having access to the information to create a trip plan that optimizes performance of the locomotive consist in accordance with one or more operational criteria for the train.

A system includes an engine and a controller. The engine is capable of multiple operating modes, and each mode has a relatively different fuel ratio such that as the engine is changed from a first operating mode having a first ratio of a first fuel to a second fuel to a second operating mode having a second ratio of the first fuel to the second fuel. The controller is operable to change the engine from one operating mode to another operating mode.
