Abstract:
A method for manually stipulating the ratio of a continuous transmission, which transmission possesses a control apparatus, a selecting apparatus, a start-up apparatus and a variator for a transitional ratio setting, the said transmission be especially that of a motor vehicle powered by an internal combustion machine, wherein the control apparatus in a first automatic operational mode automatically selects and adjusts the transmission ratio in relation to an emitted signal from a driver-vehicle system and in a second manual operational mode, the driver, by means of the selecting apparatus, can intervene directly into the choice of the transmission ratio, whereby in the said second operational mode, pre-stipulated, vehicle speed dependent motor speed of rotation (RPM) curves (3, 4, 5, 6, 7, 8) or pre-stipulated, vehicle speed dependent ratio curves, or pre-stipulated, vehicle speed dependent variator input RPM curves are manually selectable, wherein the motor RPM curves or the ratio curves, or the variator input RPM curves are so formulated as curve profiles between a lower limit (LOW) of the transmission adjustable area and an upper limit (OD) of the transmission adjustable area, that in the case of each curve, vehicle stillstand and the highest vehicle speed can be attained.
