SYSTEMS AND METHODS FOR COMMUNICATIONS BASED RAIL VEHICLE CONTROL
First Claim
1. A rail vehicle system comprising:
- a first version of a travel database including travel information;
a communication link to receive a second version of the travel database; and
a controller configured to, in response to the second version of the travel database including changes to the travel information that meet one or more predefined override criterion, control operation of the rail vehicle system based on the first version of the travel database; and
in response to the changes to the travel information not meeting the one or more predefined override criterion, adjust operation of the rail vehicle system to operate based on the second version of the travel database.

Abstract
Systems and methods for controlling a rail vehicle are provided. In one embodiment, a rail vehicle system includes a first version of a travel database including travel information, a communication link to receive a second version of the travel database, and a controller configured to, in response to the second version of the travel database including changes to the travel information that meet predefined override criteria, control operation of the rail vehicle system based on the first version of the travel database; and in response to the changes to the travel information not meeting the predefined override criteria, adjust operation of the rail vehicle system to operate based on the second version of the travel database.

10. A method for controlling operation of a rail vehicle, comprising:
-
controlling operation of the rail vehicle based on a first version of a travel database including travel information; receiving a second version of the travel database and/or information about the second version of the travel database; in response to the second version of the travel database including changes to the travel information that meet one or more predefined override criterion, continue controlling operation of the rail vehicle based on the first version of the travel database; and in response to the changes to the travel information not meeting the one or more predefined override criterion, adjusting operation of the rail vehicle system to operate based on the second version of the travel database. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A control method for a vehicle, the method comprising:
-
determining if differences in travel information content between a first version of a travel database and a second version of a travel database meet one or more predefined criterion, the first version of the travel database located on board the vehicle; if so, controlling the vehicle based on one of the first version of the travel database or the second version of the travel database; and if not, controlling the vehicle based on the other one of the first version of the travel database or the second version of the travel database. - View Dependent Claims (19, 20, 21, 23, 24)

22. A system comprising:
-
a first version of a travel database including travel information, the first version having a first checksum; a communication link to receive a second version of the travel database having a second checksum; and a controller configured to, in response to the first checksum equaling the second checksum, control operation of the rail vehicle system based on the first version of the travel database, set a value in an override register to zero, and send, through the communication link, a verification including a result of a sum of the value and the first checksum to indicate that the first version of the travel database is acceptable for movement authority of the rail vehicle system, in response to the first checksum not equaling the second checksum and the changes meeting one or more predefined override criterion, control operation of the rail vehicle system based on the first version of the travel database, set the value in the override register to a difference between the first checksum and the second checksum, and send, through the communication link, a verification to including a result of a sum of the value and the first checksum to indicate to the wayside device that the first version of the travel database is acceptable for movement authority of the rail vehicle system, and in response to the first checksum not equaling the second checksum and the changes not meeting the one or more predefined override criterion, set the value in the override register to a number that is not the difference between the first checksum and the second checksum, send, through the communication link, a verification including a result of a sum of the value and the first checksum to indicate that the first version of the travel database is not acceptable for movement authority of the rail vehicle system, and prior to establishing movement authority of the rail vehicle system, adjust operation of the rail vehicle system to operate based on the second version of the travel database.

25. A vehicle system comprising:
-
a control module having a first interface module for interfacing with a communication link of a vehicle and a second interface module for interfacing with a memory that stores a first version of a travel database; wherein the control module is configured to determine if differences in travel information content between the first version of the travel database and a second version of the travel database meet one or more predefined criterion, and if so, the control module is configured to carry out a first operation comprising one of leaving the first version of the travel database as-is in the memory or replacing the first version of the travel database with the second version of the travel database in the memory, and if not, the control module is configured to carry out a second operation comprising the other one of leaving the first version of the travel database as-is in the memory or replacing the first version of the travel database with the second version of the travel database in the memory.
