1. A method for managing a power flow in a vehicle including a powertrain system and a traffic sensing system, comprising:
- determining a present location and a trajectory of the vehicle;
determining traffic level information based on the present location and trajectory;
predicting a speed profile for the vehicle based upon the traffic level information of the vehicle only when a current vehicle speed is less than a threshold speed, a distance between the present location of the vehicle and a stopping location is less than a threshold distance, and at least one lane adjacent to the vehicle includes traffic; and
operating the powertrain to manage power flow in the vehicle based upon on the predicted speed profile.

Abstract
A vehicle includes a powertrain system and a traffic sensing system. Power flow in the vehicle is managed by determining a present location and a trajectory of the vehicle, and determining traffic level information based on the present location and trajectory. A speed profile for the vehicle is predicted based upon the traffic level information of the vehicle and the powertrain is operated to manage power flow in the vehicle based upon on the predicted speed profile.
