Patent attributes
A maximum required electric energy for operating a vehicle along a final section of the route under electric power alone when using a specified number of electrically operated devices is estimated. A maximum total electric energy required to operate the vehicle along the route is estimated. An alternate route is determined based on determining the detected stored electric energy is less than the estimated maximum total electric energy required to operate the vehicle along the route. The alternate route is determined based on an estimated maximum total electric energy required to operate the vehicle along the alternate route being greater than or equal to the detected stored electric energy. One of a) the determined alternate route, or b) based on determining no alternate route exists, a notification is output via a human/machine interface.
