The present invention relates to a transmission hydraulic pressure control method of a vehicle. The transmission hydraulic pressure control method of the vehicle of the present invention comprises the following steps of: accumulating factors representing a vehicle usage amount; accumulating factors representing a driving tendency of a driver; dalculating a line pressure compensation value according to the usage amount according to accumulated values of the factors representing the usage amount of the vehicle; calculating the line pressure compensation value according to the driving tendency of the driver according to accumulated values of the factors representing the driving tendency of the driver; determining a final line pressure by adding the line pressure compensation value according to the usage amount and the line pressure compensation value according to a tendency to a basic line pressure; and driving a transmission hydraulic apparatus according to the final line pressure. An objective of the present invention is to provide the transmission hydraulic pressure control method of the vehicle, enabling smooth and stable operability of a transmission to be secured and maintained. 본 발명은 차량의 사용량을 대표하는 인자들을 누적하는 단계; 운전자의 운전 성향을 대표하는 인자들을 누적하는 단계; 상기 차량의 사용량을 대표하는 인자들이 누적된 값에 따라, 사용량에 따른 라인압 보상값을 산출하는 단계; 상기 운전자의 운전 성향을 대표하는 인자들이 누적된 값에 따라 성향에 따른 라인압 보상값을 산출하는 단계; 상기 사용량에 따른 라인압 보상값과 상기 성향에 따른 라인압 보상값을 기본라인압에 더하여 최종라인압을 결정하는 단계; 상기 최종라인압에 따라 변속기 유압장치를 구동하는 단계를 포함하여 구성된다.
