Method and system for obtaining reference signals for vehicles control systems and corresponding control system
A method for obtaining reference signals for vehicle control systems, in function of a vehicle geographical position along a travel route, includes providing data relating to the vehicle and data relating to a route to travel, and determining a vehicle driving force reference signal and a vehicle speed reference signal through a first optimisation process configured to optimise the driving force along the travel route.
