1. A vehicle comprising:
- an electric machine configured to propel the vehicle using battery power; and
a controller programmed to operate the electric machine along a predetermined route based on a superposition of a plurality of partitionings of upcoming portions of the route, wherein each of the partitionings is based on a different set of upcoming static and dynamic resistive force characteristics associated with the route and defines at least one segment transition, and wherein each of the segment transitions defines an end of a previous segment and a beginning of a subsequent segment such that no two adjacent segments of the superposition are defined by a same set of upcoming static and dynamic resistive force characteristics.

Abstract
A vehicle includes an electric machine configured to propel the vehicle using battery power. The vehicle also includes a controller programmed to operate the electric machine along a predetermined route based on a superposition of a plurality of partitionings of the route. Each of the partitionings is based on a different force characteristic associated with the route and defines at least one segment transition, where each segment transitions defines an end of a previous segment and a beginning of a subsequent segment. The predetermined route segments are such that no two adjacent segments of the superposition are defined by a same force characteristic.

6. A method of operating a vehicle comprising:
-
partitioning a predetermined route based on an upcoming static route characteristic into a first series of segments each defined by a first segment transition; receiving an upcoming dynamic route characteristic from an external source; partitioning the predetermined route based on a second the upcoming dynamic route characteristic into a second series of segments each defined by a second segment transition; superposing the first and second series of segments to define the route such that no two adjacent route segments are defined by a same route characteristic; and operating an electric machine along the predetermined route based on resistive forces associated with the superposed segments. - View Dependent Claims (7, 8, 9, 10, 11)
