A control process for mode change decisions for an infinitely variable transmission with several modes of operation including at least two parallel coupling paths, each containing a closed coupler for the first mode of operation and open for a second mode of operation, with the two couplers being closed simultaneously during a delay period during the mode changes, wherein the mode change decision is imposed onto the transmission if the speed differential at the terminals of the coupler to be closed to change the mode, exceeds a first pre-established threshold.
