Abstract
In order to reduce the amount of time from when signals are sent to solenoid valvesfor adjusting hydraulic pressures inside hydraulic pressure chambers of various hydraulic devicesassembled in a continuously variable transmission device until the hydraulic pressures are actually changed is shortened, the solenoid valvesadjust the hydraulic pressures inside hydraulic pressure chambers connected to hydraulic introduction paths where the solenoid valvesare provided by adjusting apertures of the solenoid valvesset according to duty cycles, and a controllerfor the solenoid valveswhen the apertures of solenoid valvesare changed beyond specified values to desired apertures, adjusts the apertures beyond the desired apertures to a state where the apertures have been changed a maximum amount, then after a specified amount of time, returns the apertures to the desired apertures.
