Abstract
An optimal driving profile is generated for vehicles provided with electric propulsion, by providing a sequence of consecutive time intervals until an arrival time and providing a plurality of accelerations that the vehicle can hypothetically take in each of the time intervals; by applying laws of uniformly accelerated motion for each of the accelerations and for each of the time intervals, hypothetical future points along the route are generated, starting from the current position and speed of the vehicle; for each of the time intervals, before analysing the subsequent time interval, it is checked whether the generated points meet all the predefined constraints; if the check has a negative outcome, the point being checked is eliminated from the plausible hypotheses; driving profiles are obtained, each defined by a respective sequence of remaining points; from among said driving profiles, the one requiring a lowest overall energy to be executed is selected.
