Abstract

In a power-shift transmission that is coupled to the engine of a vehicle and uses a frictional slip clutch as a power-shift clutch, the gear-shifting process is controlled under a method wherein the torque generated by the engine and the clutch torque transmitted through the frictional slip clutch are varied in such a manner that the temperature rise of the frictional slip clutch is lessened.
