ABSTRACT:
Engine torque is managed, particularly during a gear change, so as to improve comfort and reduce wear of the engine and components associated therewith. A transmission control module is adapted to determine start and end times for torque management on the basis of a plurality of look-up tables stored in memory which are accessed via one or more engine operating parameters determined from a plurality of sensors. The contents of the look-up tables are determined experimentally to give the most appropriate start and end times for the given conditions, and not on the basis of any mathematical formula.
