Abstract
An energy-management system of a train includes a consist disengagement module configured to control disengagement of a train consist from an autonomous mode to a manual mode of operation. After receiving an instruction to disengage, the system determines an engaged power of the consist in the autonomous mode and calculates an effective position for a consist throttle where the consist would generate a disengaged power in manual mode most closely approximating the engaged power. After causing the throttle handle to be moved to the effective position, the consist disengagement module incrementally changes the operational settings for either a lead locomotive or a trail locomotive until the operational settings match the effective position for the consist throttle. The system chooses the changes to maintain the consist output power close to the disengaged power, avoiding surges in consist power and minimizing handling disturbances during disengagement.
