Abstract
A method of operating a vehicle includes generating initial state of charge and vehicle velocity profiles for a travel route, for each initial velocity setpoint defining the vehicle velocity profile, generating a plurality of updated state of charge setpoints, for each of the initial velocity setpoints, selecting one of the updated state of charge setpoints to define an updated state of charge profile, for each of the updated state of charge setpoints that defines the updated state of charge profile, generating a plurality of updated velocity setpoints, for each of the updated state of charge setpoints that defines the updated state of charge profile, selecting one of the updated velocity setpoints to define an updated velocity profile, and controlling operation of an electric machine and engine according to the updated state of charge profile and updated velocity profile over the travel route.
