The present invention relates to a posture control method for a vehicle. A main objective of the present invention is to provide a method capable of determining minute understeer or oversteer tendencies of vehicles, and controlling the posture of a vehicle if an understeer or an oversteer tendency is recognized while the vehicle is running straight. To achieve the objective, the posture control method for a vehicle comprises: a step in which a controller determines whether torque is applied to a driving wheel while a vehicle is running; a step in which the controller acquires equivalent inertia information of a drive system in real time based on operating information of the drive system if torque is determined to be applied to the driving wheel; and a step in which the controller determines an understeer or an oversteer of the vehicle from the equivalent inertia information acquired in real time.

    본 발명은 차량의 자세 제어 방법에 관한 것으로서, 차량의 미세한 언더스티어나 오버스티어 경향을 판단할 수 있고, 차량의 직진 중 언더스티어 또는 오버스티어 경향을 인지한 경우 차량의 자세를 제어하는 방법을 제공하는데 주된 목적이 있는 것이다. 상기한 목적을 달성하기 위해, 제어기가 차량의 주행 중 구동륜에 토크가 인가되고 있는지를 판단하는 단계; 제어기가 구동륜에 토크가 인가되고 있음을 판단한 경우 구동계 작동 정보에 기초하여 구동계의 등가관성 정보를 실시간으로 취득하는 단계; 및 제어기가 상기 실시간으로 취득되는 등가관성 정보로부터 차량의 언더스티어 또는 오버스티어를 판단하는 단계를 포함하는 차량의 자세 제어 방법이 개시된다.
