a decelerating event* based on the analysis of driving routes and road con‐
ditions of the navigation. It encourages
the driver to remove foot from the pedal and allow coasting down the road
with EV motor only. This helps prevent
unnecessary fuel consumption and in‐ creases fuel efficiency. ❈ Example of a deceleration event is
going down an extended hill, slow‐ ing down approaching a toll booth,
and approaching reduced speed
zones.
