Abstract: A method of limiting a maximum speed of a vehicle comprises steps of changing a set speed of the vehicle; tuning a fuel injection map according to the change in the set speed; changing the amount of injected fuel to a predetermined percentage of the maximum amount of injected fuel based on the fuel injection map when the driving speed of the vehicle reaches the set speed level; and changing the speed of the vehicle according to a gradient of a road or whether the vehicle is loaded.

Abstract: A cable holding device for accelerator pedals, allowing a driver to easily and conveniently drive a vehicle at a constant speed without continuously putting his foot down on an accelerator pedal, is disclosed. In the device, an accelerator cable connects an accelerator pedal to an engine's injection pump. A rod is provided at an end of the cable for connecting the injection pump and has a plurality of grooves on the outer surface. A cable holding unit selectively holds the rod so as to hold the cable at a previous state, thus allowing the vehicle to run at a constant speed when a pressure force is removed from the pedal. The device also has an actuating unit, which selectively actuates the cable holding unit so as to hold the cable by the cable holding unit.
