Abstract
The invention relates to a method of inputting the actual transmission ratio of a continuously variable transmission (CVT=continuously variable transmission) of a vehicle, especially a passenger motor vehicle. For this method, operating points of a shift characteristic field can be assumed which lie on a characteristic line of optimized consumption of a motor characteristic field of a motor of a vehicle. In this method, also operating points of the shift characteristic field can be assumed which lie on a characteristic line of optimized power of the motor characteristic field. The trace of the characteristic line of the shift characteristic field results from the particular selected characteristic line of the motor characteristic field. It is provided that operating points of the shift characteristic field can be assumed which lie on a dynamic characteristic line (c"') of the motor characteristic field. The dynamic characteristic line (c"') lies between the characteristic line (c') of the optimized consumption and the characteristic line (c") of the optimized power. The position of the dynamic characteristic line (c"') is dependent upon the magnitude of the rate of change of the po…
