Abstract: Systems and method of calibrating a range measurement system for a vehicle mounted on a guideway are disclosed. In some embodiments, a method includes: measuring a first time of transmission (TOT) between a first internal component of an on-board range measurement device and a second internal component of a wayside range measurement device. The first TOT is compared with a first pre-determined time. A health of the range measurement system is determined based on a difference between the first TOT and the first pre-determined time.

Abstract: A system comprises a set of sensors on a first end of a vehicle having the first end and a second end, and a controller. The sensors are configured to generate corresponding sensor data based on a detected marker along a direction of movement of the vehicle. A first sensor has a first inclination angle with respect to the detected marker, and a second sensor has a second inclination angle with respect to the detected marker. The controller is configured to compare a time at which the first sensor detected the marker with a time at which the second sensor detected the marker to identify the first end or the second end as a leading end of the vehicle, and to calculate a position of the leading end of the vehicle based on the sensor data generated by one or more of the first sensor or the second sensor.

Abstract: A method of determining a position of a vehicle on a guideway includes detecting a position of the vehicle relative to a first reflective positioning element along the guideway. The method also includes detecting a unique identification code of a transponder along the guideway, wherein the transponder is located a first known distance along the guideway from the first reflective positioning element. The method further includes determining the position of the vehicle, using a position determining system, based on a modulated reflection signal received from the transponder, a first non-modulated reflection signal received from the first reflective positioning element, and the first known distance.

Abstract: A system and method provide the capability to dynamically measure the diameter of a train wheel. An onboard sensor signals detection and loss of detection of a proximity plate having a predetermined length and placed along a direction of travel of the train. A signal generator generates a signal indicating the number of revolutions of the wheel. Based on the sensor signals indicating detection and loss of detection of the proximity plate, the length of the proximity plate, and the corresponding number of wheel revolutions, a controller automatically calculates the wheel diameter.

Abstract: Disclosed is a method of controlling a load in a railway signaling system, the method comprising providing a first autonomous controller connectable to the load and a second autonomous controller which is redundant with the first controller such that there is no single point of failure; operating the first and second controllers in one of two modes. There is an on-line mode wherein both controllers provide power to the load to control the load such that current through the load is shared between the first and second controllers. There is an off-line mode wherein a single controller does not provide power to the load and the other controller continues to operate on-line to control the load, whereby control of the load is uninterrupted.

Abstract: A localization system for a vehicle running on a guideway including portions obscured from satellite view has a number of GNSS receivers placed at strategic locations along the guideway in view of navigation satellites. GNSS transmitters retransmit received GNSS signals along an obscured portion of the guideway. Coded targets are placed at known locations along the guideway. A GNSS receiver on the vehicle picks up GNSS signals directly from the navigation satellites or retransmitted from the GNSS transmitters when on an obscured portion of the guideway. A proximity sensor on the vehicle detects the coded targets. An on-board computer synchronizes the location obtained from the GNSS signals with the location obtained from the proximity sensor. The vehicle is thus able to determine its position even in an obscured portion, such as a tunnel.
