First Claim
Patent Images
1. A method comprising;
- controlling a vehicle having mechanical and electromechanical power sources using a controller having an adaptive algorithm learning a driver'"'"'s driving preference, the controller;
monitoring a driver'"'"'s driving style during a defined term of a given driving event;
providing advisory feedback information for a vehicle operating condition based on the driver'"'"'s driving preference; and
monitoring reaction to the advisory feedback information to determine frequency of acceptance and rejection.

Abstract
A vehicle powertrain controller includes a fuzzy logic-based adaptive algorithm with a learning capability that estimates a driver'"'"'s long term driving preferences. An adaptive algorithm arbitrates competing requirements for good fuel economy, avoidance of intrusiveness and vehicle drivability. A driver'"'"'s acceptance or rejection of advisory information may be used to adapt subsequent advisory information to the driving style. Vehicle performance is maintained in accordance with a driver'"'"'s driving style.
