A method is provided for controlling a hybrid vehicle powertrain,
including recording a starting and ending point of a desired route,
determining an optimally fuel efficient route, and executing a powertrain
control strategy based on the route. Real-time traffic data and
topographical data are continuously evaluated, and the route and
powertrain control strategy are updated based on the data. A hybrid
vehicle is also provided having an engine, a motor/generator, a battery,
and a navigation system for receiving a route starting point and ending
point. A powertrain control module (PCM) detects the battery charge and
determines a powertrain strategy along an optimally fuel efficient route
based on the detected charge level when the points are selected, and
sustains the charge level in the absence of user-selected route points.
Sensors receive real-time traffic data, and the navigation system
includes topographical data for determining the optimally fuel efficient
route.
