A method/system for maintaining the energy efficiency history of predicted route segments in a database, providing adaptive feedback to hybrid vehicle controls, and displaying the energy efficiency history to the driver. As the vehicle travels on a route, the system stores energy efficiency information for route segments. The system may include sensors, a memory, and a processor to learn energy efficiency information based on how fuel and battery power are used over a route segment and/or route. The method/system may utilize energy efficiency information to adjust a start/stop engine threshold of a hybrid vehicle. When the processor predicts that the vehicle will travels on the predicted route segment again, the vehicle may optimize powertrain parameters such as the start/stop engine threshold during traveling on the predicted route segment and/or before reaching the predicted route segment.
