ENGINE SPEED CONTROL SYSTEM AND CONTROL METHODS OF AGRICULTURE VEHICLE

摘要

A system for controlling the engine rotation number of an agricultural vehicle with an electronic engine and a method for controlling the same are disclosed. According to an one aspect of the present invention, the system for controlling the rotation number comprises: a detecting means which has two left and right brakes to stop each left and right wheel and detects whether the two brakes are interworked; an engine cruise control (ECC) ON/OFF switch into which an operation command is input to maintain the rotation number of an engine at constant speed; and an engine control unit (ECU) which controls the rotation number of an engine with a predetermined value set using a foot accelerator or a hand accelerating lever at constant speed when an electrical signal is input through the ECC ON/OFF switch. In an engine cruise control (ECC) mode induced by switching on the ECC ON/OFF switch, the system for controlling the rotation number controls the ECC mode to be maintained or ended depending on interworking between the brake pedals detected by the detecting means.
