The present invention comprises the following steps of: determining whether a vehicle driving condition required for learning a tire dynamic load radius is satisfied; determining whether the state in which the vehicle driving condition is satisfied is maintained for more than a predetermined standard time; and when the vehicle driving condition is maintained more than the predetermined time, calculating the tire dynamic load radius by using a GPS-based vehicle velocity and a transmission input shaft velocity sensing value and updating the tire dynamic load radius by using the calculated value. According to the present invention, various controls on a vehicle using the dynamic load radius are accurately performed to improve marketability of the vehicle.

    본 발명은 타이어 동하중 반경 학습에 필요한 차량 주행 조건이 충족되는지 판단하는 단계; 상기 차량 주행 조건을 만족하는 상태가 소정의 기준시간 이상 유지되는지 판단하는 단계; 상기 차량 주행 조건이 기준시간 이상 유지되면, GPS 기반 차속과 변속기 입력축 속도 센싱값을 사용하여, 타이어 동하중 반경을 산출하고, 산출된 값으로 타이어 동하중 반경을 업데이트하는 단계를 포함하여 구성된다.
