  • Method and device for controlling an automatic transmission
    Patent number: 8162798
    Abstract: The invention relates to a method for controlling an automatic transmission having a torque converter, with the transmission having three gear sets and with the first gear set which has a first brake clutch and a second brake clutch being braked relative to the housing by means of simultaneous actuation of the first and second brake clutches, as a result of which an output shaft which is directly connected to the first gear set is likewise braked. The third gear set is connected in terms of gearing to an input shaft and to the first gear set and can be fixed relative to the housing by means of a third brake clutch. The simultaneous actuation of the first and second brake clutches takes place at least intermittently with the third brake clutch in a slipping state, controlling the speed of the torque converter relative to the engine.
