Abstract
(EN) Disclosed are a control system and control method for engine RPM of an agricultural vehicle having an electronic engine. The RPM control system, according to one aspect of the present invention, comprises: a detection means which has left and right brake pedals for stopping the rotation of left and right wheels, respectively, and which detects whether or not the two brake pedals are interlocked to each other; an engine cruise control (ECC) ON/OFF switch for receiving an operating command for maintaining the RPM at a normal speed; and an engine control unit (ECU) for normally controlling the RPM according to a value set by a foot accelerator pedal or a hand accelerator lever when an electrical signal is received through the ECC ON/OFF switch, wherein a control for maintaining or releasing an ECC mode is carried out according to whether the interlocking of the brake pedals is detected by the detection means in the ECC mode according to the ON state of the ECC ON/OFF switch.
(FR) La présente invention concerne un système de commande et un procédé de commande du régime moteur d'un véhicule agricole ayant un moteur électronique. Le système de commande du régime moteur, selon un aspect de la présente invention, comprend : un moyen de détection qui a des pédales de frein gauche et droite destinées à arrêter la rotation des roues gauches et droites, respectivement, et qui détecte si les deux pédales de frein sont verrouillées l'une à l'autre ; un commutateur marche/arrêt de régulateur de vitesse (ECC) destiné à recevoir une commande opérationnelle pour maintenir le régime moteur à une vitesse normale ; et une unité de commande du moteur (ECU) destinée à commander normalement le régime moteur en fonction d'une valeur définie par une pédale d'accélérateur au pied ou un levier d'accélérateur à la main lorsqu'un signal électrique est reçu par l'intermédiaire de la commande marche/arrêt ECC, une commande de maintien ou de sortie d'un mode ECC étant effectuée selon que le verrouillage des pédales de frein est détecté par le moyen de détection dans le mode ECC en fonction de l'état marche du commutateur marche/arrêt ECC.
(KO) 전자식 엔진을 장착한 농작업 차량의 엔진 회전수 제어시스템 및 제어방법이 개시된다. 본 발명의 일 측면에 따른 회전수 제어시스템은, 좌, 우 주행륜 각각의 제동을 위한 두 개의 좌, 우 브레이크 페달을 구비하며, 두 브레이크 페달의 연동 여부를 검출하는 감지수단, 엔진 회전수를 정속으로 유지시키기 위한 작동명령이 입력되는 ECC(Engine cruise control) 온(ON)/오프(OFF) 스위치, ECC 온/오프 스위치를 통해 전기적 신호가 입력되었을 때 풋 악셀 페달 또는 핸드 악셀 레버에 의해 설정된 값으로 엔진 회전수를 정속 제어하는 엔진제어유닛(ECU);을 포함하고, ECC 온/오프 스위치 온(ON)에 따른 ECC 모드(Engine cruise control mode)에서 감지수단이 검출하는 브레이크 페달의 연동 여부에 따라 ECC 모드를 유지시키거나 해제시키는 제어가 행해지도록 된 것을 구성의 요지로 한다.
