摘要： An electro-hydraulic control for a continuously variable transmission includes a first regulator valve which is controlled to provide a high pressure output to control the ratio within the continuously variable transmission and a second regulator valve which is controlled to provide an engagement pressure for torque transmitting mechanisms within the transmission. The control incorporates multiplexing of the valve components, creates prioritization of fluid flow, detection of priority mode of operation, over-pressurization protection valves, and ensures a minimum of fluid flow to the torque transmitting mechanisms and the oil cooler.

摘要： An electro-hydraulic control mechanism provides controlled engagement pressure for both a torque converter clutch and a shifting torque transmitting mechanism. The control mechanism include a TCC regulator valve that establishes the engagement pressure for the torque converter clutch and a TTM regulator valve that controls the engagement pressure for the torque transmitting mechanisms. An electronically-controlled variable bleed solenoid controls the output pressure level of both of the regulator valves. A control valve is employed to multiplex the output of the regulator valves and to ensure that the torque transmitting mechanism remains engaged during the engagement of the torque converter clutch. The control valve also ensure that the output pressure of the TTM regulator valve is communicated with a manual control valve in the event of an unexpected discontinuance of electrical power.
