Abstract:
A vehicle driven by an internal combustion engine comprising:a power transmission device being provided between a crankshaft of said internal combustion engine and drive wheels of said vehicle and having a centrifugal clutch to be connected at a speed equal to or higher than a predetermined clutch-in speed; a generator driven by said internal combustion engine; mode selection means for selecting a control mode of said internal combustion engine between a vehicle driving mode and a generating mode; a control device having engine control means for controlling said internal combustion engine so as to rotate said internal combustion engine at a rotational speed required for generating a nominal output from said generator when said mode selection means selects the generating mode, wherein the rotational speed required for generating the nominal output from said generator is set between an idle rotational speed and said clutch-in speed of said internal combustion engine and wherein said control device comprises overspeed limiting means for limiting the rotational speed of said internal combustion engine below a limit value, and limit value switching means for switching said limit value so that said limit value is suited for driving vehicle when said mode selection means selects the vehicle driving mode, and said limit value is below said clutch-in speed when said mode selection means selects the generating mode.
