Abstract
Control method for effecting a gear shift in a stepped automatic transmission with an input shaft and an output shaft for transmitting power between two inertia components at distinct speed ratios with a first power transmission path and a second power transmission path being provided with a high clutch having an adjustable torque transmitting capacity Tand a low clutch having an adjustable torque transmitting capacity Trespectively. The method includes the steps of determining a gear set input torque Tin to be transmitted by the transmission in the direction from the input shaft to the output shaft and controlling the torque transmitting capacities Tand Tin dependency on the gear set input torque Tto be transmitted such that: a) if T>=0 then T=Tand T=0 b) if T<0 then T=0 and T=T.
