## 4 Conclusions
The replanning strategy can further exploit the fuel saving potential of the engine at high power and reduces its inefficient operation at low power when the actual vehicle speed significantly deviates from the predicted speed of the original plan, which can reduce at least 9-10% of fuel consumption compared with the original strategy.
