摘要
A method is provided for controlling an engine to allow a driver to obtain a working range of the engine in excess a base working range thereof The method includes establishing a base working range, which limits are defined by a base torque versus engine speed curve, establishing an excess working range, which limits are defined between the base torque versus engine speed curve and an excess torque versus engine speed curve, the excess torque versus engine speed curve displaying a higher maximum torque level and/or a higher end engine speed as compared to the base torque versus engine speed curve, establishing an excess availability limit, defining the maximum duration or maximum distance of access to the excess working range per unit time or unit distance, calculating a cumulative consumed excess value per unit time or unit distance by summating any time periods or distances during which the excess working range is accessed within the unit time or unit distance, and controlling the engine in response to driver input to allow access to the excess working range only when the cumulative consumed excess value is less than the excess availability limit.
