Abstract
A host vehicle includes a combustion engine configured to provide a propulsion torque to satisfy a propulsion demand. The vehicle also includes at least one sensor configured to detect a position of a reference vehicle. A vehicle controller is programmed to determine a path between a current host vehicle location and an upcoming intersection. The controller is also programmed to forecast a path clearance time at which the host vehicle is able to traverse the intersection in response to sensor data indicating the reference vehicle moving within the path ahead of the host vehicle. The controller is further programmed to deactivate the engine prior to a host vehicle stop based on the path clearance time being greater than a time threshold.
