Abstract:
A power transfer system for a vehicle having a power source providing a source of input torque and a driveline, said power transfer system comprising:a power-interrupt auto-manual transmission adapted for connection with said power source and said driveline to provide said driveline with a first level of drive torque, said power-interrupt auto-manual transmission including a plurality of gear ratios for controlling a speed of said vehicle and means for interrupting the distribution of said first level of drive torque to said driveline during a shift between said gear ratios;means for providing a second level of drive torque to said driveline operable during at least a portion of said shift; andengine throttle controls for controlling a delivery of air to said power source during at least a portion of said shift wherein said engine throttle controls are for controlling a rotational speed of said power source during said at least a portion of said shift to maintain said rotational speed of said power source at a speed substantially equal to the rotational speed of said power source just prior to said shift.
