1. A vehicle comprising:
- at least one controller programmed to operate a traction battery to achieve upon completion of a present route segment a target state of charge that is based on a target battery power defined by a classification for a plurality of route segments including the present route segment that results from application of a set of fuzzy rules to vehicle acceleration and road grade associated with the route segments.

Abstract
In a vehicle, a controller divides a route into route segments. The controller operates a traction battery over the route segments to achieve a target state of charge upon completion of one of the route segments. The target state of charge is based on a target battery power defined by a classification for each of the route segments including the one of the route segments according to a set of fuzzy rules applied to vehicle acceleration and road grade associated with the route segments. Fuzzy rules may be applied to the classification for each of the route segments.

10. A method comprising:
-
generating, by a controller, a classification for a plurality of route segments based on a set of fuzzy rules applied to vehicle acceleration and road grade for each of the route segments; and operating, by the controller, a traction battery over a present route segment to achieve upon completion of the present route segment a target state of charge derived from a target battery power that is based on the classification. - View Dependent Claims (11, 12, 13, 14)
