Vehicle communication system and method
A system that includes a lead locomotive in communication with one or more remote vehicles, and the lead locomotive including one or more processors configured to execute program instructions to perform functions based on the program instructions. These functions include determining a first characteristic related to the lead locomotive or the one or more remote locomotives, receiving historical data related to the first characteristic, comparing the first characteristic to the historical data to determine a change in first characteristic value, and determining a second characteristic related to the lead locomotive or the one or more remote locomotives. In response to the change in first characteristic value exceeding a threshold percentage, the one or more processors ignore the change in first characteristic value exceeding the threshold percentage based on the second characteristic.
1. A vehicle control system comprising:
a lead vehicle in communication with one or more remote vehicles;
the lead vehicle including one or more processors configured to execute program instructions to:
determine a first characteristic related to the lead vehicle or the one or more remote vehicles;
receive historical data related to the first characteristic;
compare the first characteristic to the historical data to determine a change in first characteristic value;
determine a second characteristic related to the lead vehicle or the one or more remote vehicles, the second characteristic indicative of a heading of one or more of the lead vehicle or the one or more remote vehicles; and
responsive to the change in first characteristic value exceeding the threshold percentage, brake at least one of the lead vehicle or one or more of the one or more remote vehicles based on the second characteristic,
wherein at least one of the first characteristic related to the lead vehicle or the one or more remote vehicles, or the change in the first characteristic value, includes a distance between a portion of the lead vehicle and a portion of at least one of the one or more remote vehicles.
2. The system of claim 1 , wherein the historical data is received from a database that is one of a memory of a lead communication device, a memory of a remote communication device, a company generated database, a positive vehicle control database, a route database, or a government based database.
3. The system of claim 1 , wherein the lead vehicle is not physically coupled to the one or more remote vehicles.
