The present invention provides a vehicle which estimates the speed of the vehicle with high reliability by selecting an appropriate wheel speed and varying calculation based on a slope on which the vehicle is placed, and a control method thereof. The vehicle according to an embodiment includes: a sensor unit for acquiring vehicle information including the speed of at least one wheel provided in the vehicle; and a control unit which determines a reliable wheel speed based on a predetermined criterion of the speed of at least one wheel, estimates the pitch angle of the vehicle and the lateral speed of the vehicle based on the reliable wheel speed, and estimates the terminal speed of the vehicle based on the reliable wheel speed, the pitch angle, and the lateral speed of the vehicle. The control unit can estimate the pitch angle based on a predetermined weight filter.

    본 발명은 적절한 휠 속을 선택하고 차량이 위치한 경사에 기초한 연산을 달리하여 신뢰도가 높은 차량의 속도를 추정하는 차량 및 그 제어방법을 제공한다. 일 실시예에 따른 차량은, 차량에 구비된 적어도 하나의 휠 속을 포함하는 상기 차량 정보를 획득하는 센서부; 및 적어도 하나의 휠 속 중 미리 결정된 기준에 기초하여 신뢰 휠 속을 결정하고, 신뢰 휠 속을 기초로 상기 차량의 피치각 및 상기 차량의 횡속도를 추정하고, 신뢰 횔 속, 피치각 및 상기 차량의 횡 속도를 기초로 상기 차량의 종속도를 추정하는 제어부;를 포함한다. 제어부는, 미리 결정된 가중치 필터를 기초로 상기 피치각을 추정할 수 있다.
