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 fusion sensor arrangement includes a first sensor configured to detect the presence of an object along a wayside of a guideway, wherein the first sensor is sensitive to a first electromagnetic spectrum. The fusion sensor arrangement further includes a second sensor configured to detect the presence of the object along the wayside of the guideway, wherein the second sensor is sensitive to a second electromagnetic spectrum different from the first electromagnetic spectrum. The fusion sensor arrangement further includes a data fusion center connected to the first sensor and to the second sensor, wherein the data fusion center is configured to receive first sensor information from the first sensor and second sensor information from the second sensor, and to resolve a conflict between the first sensor information and the second sensor information.

Abstract: A system comprises a speed detector, a marker sensor, a controller, a sensor unit, and a processor. The speed detector is configured to generate speed data associated with a movement of a vehicle. The marker sensor is configured to generate marker data based on a detection of an object along a wayside of a guideway. The controller is configured to calculate a distance the vehicle moved, generate location information, and generate an indication the vehicle is stationary. The sensor unit comprises an accelerometer, a gyroscope, and a magnetometer. The sensor unit is configured to generate sensor data based on information gathered by one or more of the accelerometer, the gyroscope, or the magnetometer. The processor is configured to process the sensor data to determine a vehicle position based on the sensor data and the location information. The controller is further configured to compare the location information with the vehicle position.
