Abstract:
PCT No. PCT/DE97/01094 Sec. 371 Date May 11, 1998 Sec. 102(e) Date May 11, 1998 PCT Filed May 31, 1997 PCT Pub. No. WO98/00658 PCT Pub. Date Jan. 8, 1998A system for changing the gear ratio with a multi-step reduction gear, where a flywheel is accelerated or decelerated during a change in gear ratio. The flywheel, consisting essentially of engine components and the converter, must be accelerated in downshifting operations, for example, while the flywheel is decelerated in upshifting operations. To change the gear ratio, at least two different selectable strategies are given. A first value representing the engine output torque and a second value representing the torque demand for acceleration or deceleration of the flywheel are detected first. To change the gear ratio, one of the above-mentioned strategies is then selected, depending on a comparison of the first value detected with the second value detected. To determine the engine output torque in the actual shifting operation, it is predicted from the instantaneous load signal and parameters that depend on the throttle valve angle.
