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 positioning and odometry system includes two or more vehicle beacons installed on an end of a vehicle and configured to communicate with one or more guideway beacons installed along a guideway. Processing circuitry is configured to communicate with the one or more vehicle beacons and perform at least one of: determine, before the processing circuitry enters a sleep state, a first vehicle position on the guideway; determine, after the processing circuitry wakes from the sleep state, a second vehicle position on the guideway; determine, after the processing circuitry wakes from the sleep state, any difference between the first vehicle position on the guideway and the second vehicle position on the guideway; determine a third vehicle position on the guideway using range measurements taken at configurable time intervals; and determine a vehicle speed where speed is measured as a change in the third vehicle position over time.

Abstract: A system for controlling a vehicle includes at least one vehicle network on board the vehicle, first and second controllers coupled to the at least one vehicle network and configured to communicate with each other via the at least one vehicle network, and first and second sensor sets coupled to the at least one vehicle network, and configured to communicate with any of the first and second controllers via the at least one vehicle network. Each of the first and second controllers is configured to, based on data output from any of the first and second sensor sets, control a movement of the vehicle independently of the other of the first and second controllers. The first sensor set is located at a first location on the vehicle, the second sensor set is located at a second location on the vehicle, and the second location is different from the first location.

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 object along a direction of movement of the vehicle. The controller is configured to compare a time at which the first sensor detected the object with a time at which the second sensor detected the object 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. The controller is also configured to generate a map of the plurality of objects based on the sensor data.

Abstract: A system and method of supervising vehicle positioning of a vehicle along a guideway where the vehicle comprising a supervisory controller, at least two controllers communicatively connected with the supervisory controller, an inertial measurement unit (IMU) and a speed measurement sensor includes receiving, by the controllers, speed measurements from the speed measurement sensor and motion measurements from the inertial measurement unit. The two controllers each estimate the along-track position of the vehicle using a track constrained UKF function based on the received speed measurements and motion measurements. The system executes protection level and protection level supervision functions on the supervisory controller to validate the along-track position estimates. The protection level supervision function uses a Stanford diagram verification technique.

Abstract: A positioning and odometry system (POS) includes one or more sensors configured to collect sensor data. The one or more sensors are operably coupled to a portable housing configured to be coupled to a vehicle body. POS has processing circuitry operably coupled to the one or more sensors. The processing circuitry is configured to determine, in response to the collected sensor data from the one or more sensors, vehicle position and odometry data.

Abstract: A system is described for determining the location of a vehicle including an on-board computer and a ground penetrating radar mounted on the vehicle that is communicably connected to the on-board computer. A reflective landmark is located at a known location along the path of the vehicle. The reflective landmark includes reflective elements arranged to encode data. The ground penetrating radar transmits signal energy and detects reflected signal energy reflected by the reflective landmark and communicates encoded data representative of the reflected signal energy to the on-board computer. The on-board computer decodes the encoded data and thereby determines the location of the vehicle.

Abstract: A method includes detecting an initialization position of a processing zone within a graphical user interface, the processing zone having boundaries and a predefined direction extending away from the initialization position, the graphical user interface comprising displayed point cloud data, the displayed point cloud data being based on a scanning of a three dimensional space. The method also includes applying a Kalman filter to the track points to identify a trajectory of a guideway and generating a model of the guideway based on the track points and the trajectory. The method further includes detecting one or more of a turnout region or an object associated with the guideway. The method additionally includes generating a map comprising the model of the guideway and one or more of the turnout region or the object, and at least one label identifying the turnout region or the object included in the map.
