Patent ID: 6869382

Claim:
In a motor vehicle having an engine and a transmission including a first clutch assembly for transferring torque from the engine to a first driven gear pair having a first gear ratio and to a second driven gear pair having a second gear ratio larger than the first gear ratio, and a second clutch assembly for transferring torque from the engine to a third driven gear pair having a third gear ratio larger than the first gear ratio and smaller than the second gear ratio, a method of double-downshifting from the first gear ratio to the second gear ratio using the same clutch assembly comprising the steps of: reducing torque transfer from the first clutch to the first driven gear; increasing engine speed; increasing torque transfer from the second clutch to the third driven gear while simultaneously disengaging the first clutch from the first driven gear; reducing torque transfer from the second clutch to the third driven gear; increasing torque transfer from the second clutch to the third driven gear; engaging the first clutch to the second driven gear; increasing torque transfer from the first clutch to the second driven gear while simultaneously reducing torque transfer from the second clutch to the third driven gear; and disengaging the second clutch from the third driven gear.
