Intelligent communications, command, and control system for a land-based vehicle

Method and communication system for a railroad train having at least one locomotive for automatically adjusting the communication system to provide effective communication of command data to control operation of the locomotive are provided. The system includes a transceiver on the locomotive. The system further includes at least one transceiver remote from the locomotive. A database may be provided for storing data relative to a plurality of communication schemes available to the communication system. A first monitor may be used for sensing a parameter indicative of the quality of the communications between the transceivers when the transceivers are operating under a first one of the available communication schemes and generating data indicative of communications quality. A processor in communication-with the monitor and the database may be configured to select a second communication scheme when the quality of the communications provided by the first communication scheme is not satisfactory to ensure that the command data will be reliably communicated with respect to the locomotive.
