Methods and Systems for Multi-Sensor Fusion Railway Vehicle Localization

A system comprising:

• a plurality of sensors coupled to a railway vehicle;
• and
• a computing system configured to:
• receive sensor data from a plurality of sensors coupled to a railway vehicle as the railway vehicle travels along a rail in an environment;
• determine, based on the sensor data, a three-dimensional (3D) position of the railway vehicle in the environment;
• determine, based on the 3D position of the railway vehicle, a two-dimensional (2D) location of the railway vehicle within a digital map of a track network comprising the rail;
• and
• provide the 2D location of the railway vehicle within the digital map of the track network to a control system of the railway vehicle.

A non-transitory computer readable medium configured to store instructions, that when executed by a computing system comprising one or more processors, causes the computing system to perform operations comprising:

• receiving sensor data from a plurality of sensors coupled to a railway vehicle as the railway vehicle travels along a rail in an environment;
• determining, based on the sensor data, a three-dimensional (3D) position of the railway vehicle in the environment;
• determining, based on the 3D position of the railway vehicle, a two-dimensional (2D) location of the railway vehicle within a digital map of a track network comprising the rail;
• and
• providing the 2D location of the railway vehicle within the digital map of the track network to a control system of the railway vehicle.
