Abstract
A method for controlling and regulating the input power distribution of prime movers in a power train () of a motor vehicle which has one internal combustion engine (), at least one electric machine (), at least one clutch (), the same as one transmission (), and in which there is at least one control and regulation unit which, on the basis of predetermined, measuring and calculated values, controls and regulates the input power distribution between the internal combustion engine () and at least one electric machine () with regard to power dynamics of the vehicle, the same as its energy consumption, its emission and its driving comfort. In addition, departing from a signalized input power wish, it is provided that existing nominal operating values for the operation of at least one electric machine () is changed to new nominal operating values adapted to the actual input power wish and to changed operating situations of the vehicle and, that to determine the new nominal operating values for at least one electric machine (), the future maximum and minimum torques and outputs are precalculated, the same as the efficiency degree or losses thereof.
