A method for CVT low oil pressure input clutch fill compensation includesperforming a garage shift when a modeled fill pressure is equal to a commanded modeled fill pressure. Then the line pressure is checked to determine if it is less than the commanded fill pressure when performing the garage shift. If so, then the modeled fill pressure is set to the line pressure and the primary and secondary actual pulley pressures are read by sensing devices. Next, the primary and secondary commanded pulley pressures are checked to determine if they are greater than the modeled fill pressure. If so, then a first dPressure value for the flow rate model based on the lowest of the modeled fill pressure, the primary actual pulley pressure, or the secondary actual pulley pressure is determined and it is used to compensate the flow rate model.

A method of controlling the electric current of a linear solenoid valve by performing pulse width modulation on a coil current for energizing a linear solenoid of the linear solenoid valve to adjust the hydraulic pressure of a working oil in a hydraulic clutch for transmitting and interrupting the rotational drive power from a power source to a drive wheel of a vehicle. The method includes setting the period of the pulse width modulation to a shorter value as the degree to which the hydraulic clutch is engaged increases from a disengaged state thereof. Here, the period of the pulse width modulation may be set in accordance with the variation of a duty ratio depending on the hydraulic pressure corresponding to the degree to which the hydraulic clutch is engaged.
