<p>PCT No. PCT/DE94/01138 Sec. 371 Date Jun. 5, 1995 Sec. 102(e) Date Jun. 5, 1995 PCT Filed Sep. 28, 1994 PCT Pub. No. WO95/09741 PCT Pub. Date Apr. 13, 1995The invention relates to a method and an apparatus for controlling the output torque (Mab) of an automatic transmission 10 during the course of a gear-shifting operation in an engine-operated vehicle. The transmission 10 has at least two gears (11, 12) which can be engaged alternatively by means of clutches (16, 17). The clutches (16, 17) and the torque (Mm) of the vehicle engine 14 are controlled according to at least two control sequences (SH1 to SH3, SR1 to SR3 or ZH, ZR) which can be selected as a function of instantaneously present gear-shifting conditions. According to the invention, in order to select the control sequences (SH1 to SH3, SR1 to SR3 or ZH, ZR) it is determined, as a gear-shifting condition, whether the vehicle is in an operating state with a positive clutch torque (engine traction operation) or in an operating state with a negative clutch torque (engine overrun operation).</p> |
