According to the present invention, in a method for maintaining improvability with respect to idle noise of a vehicle, threshold values of the vehicle speed and the engine cooling water temperatures and threshold values of brake pedal effort conditions are individually applied by a controller (10) in an idle stop and go (ISG) ON state of an engine (3-1) when performing a D-stage neutral control operation for D-stage idle slip control of a transmission unit (3-2). The operational state is switched to an auto-hold mode by selectively applying the individual threshold values, thereby restricting the auto-hold control which is previously switched only when a driver releases the brake in the D-stage neutral control operation. As a result, even when the auto-hold control and D-stage neutral control modes are realized together, the vehicle (1) can prevent degradation of the product value related to D-stage idle noise, vibration, and harshness (NVH) attributes by maintaining the D-neutral control state in the D-neutral control mode.

    본 발명의 차량의 아이들 소음 향상성 유지방법은 변속기(3-2)의 D단 아이들 슬립 제어를 위한 D단 중립제어시 엔진(3-1)의 ISG(Idle Stop & Go) ON상태에서 컨트롤러(10)에 의해 차속과 엔진냉각수온 조건의 임계값과 브레이크페달 답력 조건의 임계값이 각각 적용되고, 각 임계값(threshold)의 선택적용으로 오토홀드(Auto Hold)로 전환됨으로써 D단 중립제어상태에서 운전자의 브레이크 조작 해지만으로 전환되던 오토홀드의 제어 개입이 제한된다. 그 결과 차량(1)은 오토홀드제어와 D단 중립제어를 함께 구현하더라도 D단 중립제어시 기존 대비 D단 중립제어 상태를 지속함으로써 D단 아이들 NVH(Noise, Vibration, Harshness) 상품성 악화가 방지되는 특징을 갖는다.
