Abstract
A communication management system for a vehicle includes a control module, a communication module, and a management module. The control module is disposed on-board a lead powered unit of the vehicle. The control module is configured to automatically change propulsion energy settings of a remote powered unit of the vehicle. The communication module transmits instructions to the remote powered unit to automatically change the propulsion energy settings of the remote powered unit. The communication module identifies communication gaps that represent interruption in one or more communication connections between the lead powered unit and the remote powered unit. The management module compares the propulsion energy settings of the lead powered unit and of the remote powered unit during the communication gaps and, based on the propulsion energy settings, prevents the control module from switching from automatic control of the propulsion energy settings of the remote powered unit to manual control.
