FIELD: transport.
SUBSTANCE: invention relates to working machines with ICE engaged with stepless transmission. Working machine comprises ICE (1C) and stepless transmission (IVT) engaged therewith. At least, one sensor generates output signal representing ICE load in real time. At least, one data processing electric circuit serves to control transmission power subject to ICE threshold and real loads. In compliance with one version, at least, one data processing electric circuit includes ICE control unit (ECU) connected with ICE (1C), and transmission control UNIT (TCU) engaged with stepwise transmission (IVT). Engine control unit (ECU) feeds output signal to transmission control unit (TCU) that represents load in real time. Transmission control unit controls transmission power output subject to threshold load and real time load. Invention relates to method of operating said working machine.
EFFECT: ruled out ICE engine overload.
