ABSTRACT:
An automotive drive system for machines and vehicles, comprising a driving motor the speed of which can be continuously varied by means of a control member and a converter having control means for controlling its output speed in dependence on a depression of the speed of the driving motor determined by means of signal transmitters is arranged so that the power or torque available from the driving motor is better employed. This is achieved by controlling (adjusting) the converter to minimum transmission ratio independently of the driving motor speed when the driving motor speed resulting during operation of the drive system is greater than the driving motor speed given by a predetermined speed(rotation) depression, and on reaching the predetermined speed (rotation) depression the converter is controlled in dependence on the driving motor speed so that the driving motor speed does not fall below the controlling characteristic curve corresponding to the predetermined speed (rotation) depression.
