Abstract
A hydraulic pressure control method for a vehicle transmission includes accumulating factors representing vehicle usage, accumulating factors representing driver's driving tendency, calculating a first line pressure compensation value according to the usage depending on the accumulated values of the factors representing the vehicle usage, calculating a second line pressure compensation value according to the driver's driving tendency depending on the accumulated values of the factors representing the driver's driving tendency, determining a final line pressure by adding the first and second line pressure compensation values according to the usage and the driver's driving tendency to a basic line pressure, and operating a transmission hydraulic system according to the final line pressure.
