  • Shifting process control and method for coordinating shifting processes
    Patent number: 6912456
    Abstract: The present invention relates to a shift sequence control to coordinate shifting, which corresponds to changes of constellations in a transmission. A change of the constellations yields a change of the force transfer of the transmission. The sequence of shifting takes place program-controlled and is subdivided into phases (0, 1, 2, 3, 4, 5, 6, 7). The sequence includes the driving of a plurality of actuating elements and each of the phases is assigned at least one type of drive for at least one actuating element. According to the invention, it is provided that the phases (0, 1, 2, 3, 4, 5, 6, 7) can be configured without changing the program. Furthermore, the present invention relates to a method for coordinating shifting sequences.
