WIPO Patent Application WO/2012/096514
Kind Code:
A2
Abstract:
Disclosed is a system for controlling the number of revolution for an engine of a farm work vehicle having an electronic engine attached thereon. The system for controlling the number of revolution according to an embodiment of the present invention comprises: a foot accelerator pedal sensor for detecting the maneuvering location of a foot accelerator pedal; a hand accelerator lever sensor for detecting the maneuvering location of a hand accelerator lever; an engine cruise control (ECC) on/off switch onto which an operation command is inputted for maintaining the number of revolution for the engine at a fixed speed; and an engine control unit (ECU) for controlling the number of revolution for the engine at a number of revolution designated according to an operation signal of the ECC on/off switch, wherein the system is configured to execute a cruise mode for maintaining the number of revolution for the engine constant according to the operation signal of the ECC on/off switch when the execution conditions are satisfied, and maintain the number of revolution for the engine to be constant at a set number of revolution after the ECU selects the bigger value from the number of revolution for the engine set according to the foot accelerator pedal and the hand accelerator lever, when the cruise mode is executed.
