OPTIMIZED POWERTRAIN WITH ROUTE-LEARNING FEATURE
First Claim
1. A vehicle powertrain having a route-learning control feature comprising:
- at least one driver input for operating the vehicle; and
a route-learning powertrain control unit connected to the at least one driver input and operable to, for a defined route, conform powertrain operation to data indicating at least one driver preference for operation of the vehicle on the defined route.

Abstract
The technology described herein provides a powertrain system with a route-learning feature. Particularly, learned information is used to optimize powertrain operation along any learned route. The learned information comprises, generally, feedback from the vehicle'"'"'s acceleration and brake sensors and information from an on-board trip computer. At the least, the powertrain is able to optimize its operation to a driver'"'"'s preference based on the feedback recorded along a particular route that the driver has specified. The route-learning powertrain control described herein is particularly useful with a hybrid powertrain, and can be used to optimize start/stop and regenerative braking control. The system described herein can also be integrated with a navigation system and GPS receiver, to provide more accurate route-learning and/or automated operation.
