Abstract: 본발명은스로틀밸브제어방법에관한것으로, 주행중아이들스로틀진입조건을만족하는지판단하는제1단계; 상기제1단계를만족하면목표공기량맵을이용하여스로틀밸브를제어함과동시에 EGR 맵을이용하여 EGR 밸브를제어하는제2단계; 상기제2단계수행중 아이들스로틀해제조건을만족하는지판단하는제3단계; 상기제3단계에서아이들스로틀해제조건을만족하면 EGR 맵복귀조건을만족하는지판단하는제4단계; 를포함하는디젤차량의아이들스로틀밸브제어방법을제공하여, EGR률을사용자가원하는양만큼사용할수 있는자유도가추가됨으로써, 기존 conventional 방식대비연비, 배기가스, 소음의최적화를위한자유도가향상시킬수 있다. 또한, EGR 율을기어변속(gear shift) 혹은오버런(over run) 조건에서원래값으로복귀시킴으로인해스로틀밸브및 EGR 밸브천이시발생하는발진시울컥거림방지및 발진소음개선에효과가있다.

Abstract: PURPOSE: A control method of an idle speed control throttle valve for a diesel vehicle is provided to improve the degree of freedom for the optimization of fuel efficiency, exhaust gas, and noise by adding the degree of freedom which allows a user to use as much EGR(Exhaust-Gas Recirculation)rate as a user desires. CONSTITUTION: A control method of an idle speed control throttle valve for a diesel vehicle comprises the following steps: determining(S110) whether a driving satisfies the entry condition for the idle speed control throttling or not; controlling(S120) a throttle valve by a target air flow map simultaneously with an EGR(Exhaust-Gas Recirculation) valve by a EGR map when the driving satisfies the entry condition for the idle speed control throttling; determining(S130) whether those performed steps satisfy the release condition of the idle speed control throttling or not; and determining(S160) whether the return condition of the EGR map is satisfied when those performed steps satisfy the release condition of the idle speed control throttling. [Reference numerals] (AA) Start; (BB,DD,FF) No; (CC,EE,GG) Yes; (S100) Normal driving; (S110) Idle throttle entry condition?; (S120) Starting idle throttle control(throttle valve control, EGR valve control); (S130) Idle throttle release condition?; (S140) Releasing the idle throttle control and returning to the existing target air flow; (S150) Maintaining the idle throttle control; (S160) EGR ratio map return condition?; (S170) Returning to the EGR ratio map
Abstract translation: 目的：提供一种用于柴油车辆的怠速控制节流阀的控制方法，通过增加允许使用者使用的自由度来提高燃油效率，废气和噪音的优化自由度 用户期望的EGR（排气再循环）率。 构成：用于柴油车辆的怠速控制节流阀的控制方法包括以下步骤：确定（S110）驾驶是否满足怠速控制节流的进入条件; 当驾驶满足怠速控制节流的进入条件时，通过EGR图与EGR（排气再循环）阀同时地通过目标气流图来控制（S120）节气门; 确定（S130）这些执行步骤是否满足怠速控制节流的释放条件; 并且当这些执行步骤满足怠速控制节流的释放条件时，确定（S160）是否满足EGR图的返回条件。 （附图标记）（AA）开始; （BB，DD，FF）否; （CC，EE，GG）是; （S100）正常驾驶; （S110）空转油门进入条件？ （S120）起动怠速控制（节气门控制，EGR阀控制）; （S130）空转油门释放条件？ （S140）释放怠速节气门控制并返回到现有的目标气流; （S150）保持怠速控制; （S160）EGR率图返回条件 （S170）返回到EGR率图
