  • Control method and control device for an infinitely variable change-speed gear
    Patent number: 6544141
    Abstract: An arrangement for controlling an infinitely variable vehicle transmission includes an adjusting element which is operable in two modes. In a first mode, the adjusting element can be actuated to select from predetermined transmission gear settings. In the second mode, it can be actuated to cause a continuous adjustment of the vehicle gear. The direction, speed and manner of such adjustment depend on the manner in which the adjusting element is actuated, and optionally vehicle operating parameters. In addition, the adjusting element can be used to select from among driving control modes based on predetermined algorithms, for achieving maximum economy or maximum performance.
