Present article shows the influence of steering course of CVT-Continuous Variable Transmission to engine load trajectory at established vehicle speed profile by engine throttle. In this aim, at the first part is shown vehicle and their driveline model. There was described simulating model and the main subsystem having major influence to analyzed problem, made near help of MatLab Simulink R2007a software. There was shown one and multi objective optimal lines conception. At the second part, there was presented proposition of CVT steering course at four Variants, and also shown results of simulating investigation for proposed Variants. At final part, there was analyzed results of simulating investigations and future work according to presented problems. Results of work showed the influence control graph of drive on the trajectory of an engine load. The control graph of stepless drive is relative to the profile of the speed and the universal engine performance. It is possible to change work range by graph choice of system, wherethrough one can exclude programmatically unfavorable areas on work of the combustion engine.
