Abstract
A method is provided for controlling speed of a vehicle. The method includes determining an arrival time error (ATE) for a required time of arrival (RTA) and a projected trajectory according to a travel plan with a current speed profile having a plurality of regions, each with a respective speed adjustment parameter (SAP) and a respective SAP value relative to a nominal speed profile. The method further includes selecting, when the ATE is greater than a threshold, one of the regions as a selected region for modification based on a priority order of the regions. The method further includes modifying the current speed profile by adjusting the respective SAP value for the selected region according to the respective SAP in order to decrease the ATE; and implementing the modified speed profile.
