PURPOSE:To make execution of an inverter control based on an invariably stable constant output control possible and to easily attain a stable running control by preparing a function in which a vehicle speed signal is made a variable and an engine output signal based on a true engine speed is made a parameter and by making the constant output control by this function be reflected on the inverter control. CONSTITUTION:An output voltage of a main generator 2 is converted into an engine speed signal (n) by a V/F converter 25, and using this signal as a variable, a function output Pn corresponding to a prescribed engine output is generated in a function generator 13. Since this function output Pn is lower than a function output PN for which a notch N of a master controller 7 is used as a variable, it is selected by a low-level preference selector 15 and corrected by a load adjustment signal from an all-speed engine governor 8 and a corrected signal PP, is inputted to a constant output control pattern generator 17. From the constant output control pattern generator 17, an output IP corresponding to the engine speed signal (n) and a rotor frequency fR of a main motor 6 is delivered as a current pattern for the main motor 6 of an inverter control device 11. |
