Adaptive real-time driver advisory control for a hybrid electric vehicle to achieve fuel economy

摘要

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.

主权项

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.
