Abstract:
A method includes energizing a solenoid valve of a hydraulic control system according to a predetermined timing schedule to move a valve member of the solenoid valve. The solenoid valve is operatively connected to the switching component by a fluid control passage, such as a passage in an engine block, to deliver pressurized fluid from a supply passage when the valve member moves to switch the switching component from a first mode to a second mode. An operating parameter of the control system is measured. The operating parameter may be a period of time over which the valve member moves, or a sensed operating parameter of the fluid, such as pressure or temperature. The measured parameter is then compared with a predetermined parameter. Energizing of the solenoid valve is then adjusted based on the difference.
