摘要：The invention concerns a method and device for controlling the output torque(Mab) of an automatic transmission (10) during the gear-change operation in an engine-powered vehicle. The transmission (10) has at least two gears (11, 12) which can beengaged by means of clutches (16, 17), the output torque (Mab) being controlled bycontrolling the clutches (16, 17) and the engine torque (Mm) in accordance with one of atleast two control procedures (SH1-SH3, SR1-SR3 or ZH, ZR) selected as a function of thegear-shift conditions existing at any particular point in time. The invention calls for thegear-shift condition governing selection of the control procedure (SH1-SH3, SR1-SR3 orZH, ZR) to be whether the vehicle is operating with a positive clutch torque (i.e. with theengine in the traction mode) or with a negative clutch torque (i.e. with the engine in theoverrun mode).
