ABSTRACT:
A process for adjusting the characteristics of infinitely variable transmissions of a vehicle with two drive mechanisms including detecting the output speeds of the transmissions and comparing them by means of an operating variable to determine the gear ratio. Adjusting the gear ratio as a function of a deviation for matching the characteristics. The characteristics are completely carried out for the operating variable and are detected and stored in a close point sequence by measuring the output speeds. When the vehicle is travelling, the deviations of the characteristics are compensated by an electronic unit which influences the predetermined operating variables so that when the transmissions are operated with the same predetermined operating variable, the output speeds are identical despite different characteristics.
