Fuel-Efficient Driving Strategies for Heavy-Duty Vehicles: A Platooning Approach Based on Speed Profile Optimization

Table 1

The normalized fuel savings obtained in the simulations for a homogeneous platoon of two 30 tonne HDVs over all the road profiles. The middle column shows the fuel savings obtained with SPO+ACC, whereas the right-most column shows the fuel savings obtained with P-SPO. The normalization was carried out with respect to the baseline case, i.e., CC+ACC where the lead vehicle drives at the constant speed of 80 km/h and the intervehicle distance is set to the allowed minimum.
