    Abstract: A hydraulic control system for distributing pressurized fluid to a multi-mode hybrid-type power transmission is provided, as well as a method for regulating the same. The hydraulic control system includes an engine-driven main pump in fluid communication with a main regulator valve, and an electrically-driven auxiliary pump in fluid communication with an auxiliary regulator valve. One pressure control solenoid provides feedback (boost) pressure to both regulator valves, and thereby modify output of the main and auxiliary pumps. A controller selectively modifies distribution of boost pressure to ensure a continuous and controllable feed of hydraulic pressure to the transmission during all vehicle operations. The method includes: determining if the vehicle is transitioning to engine auto-start or auto-stop; determining the line pressure requirements of the transmission under current operating conditions; starting the oncoming-pump; adjusting PCS command so started oncoming-pump pressure equals line pressure requirements; and shutting down off-going-pump.

    Abstract: A transmission includes first and second clutch members rotatable about the same axis. An axial groove is formed in one of the members to distribute lubricating fluid to the other member. Preferably, clutch plates with radial grooves extend between the clutch members. Fluid flows from the axial groove through the radial groove and across faces of the clutch plates to separate the plates during disengagement in order to minimize spin losses.

    Abstract: An assembly and method is provided for reducing clutch wear due to centrifugal apply pressure within a clutch-apply cavity. The assembly comprises a rotatable clutch housing, a clutch-apply piston disposed within a clutch-apply cavity, and a balance piston. The balance and apply pistons define a balance cavity including a liquid fill channel and a dedicated air exhaust channel having a control radius configured to at least partially offset or compensate for the centrifugal apply force generated within the clutch-apply cavity when the clutch assembly rotates. The method includes configuring the balance cavity with an exhaust channel for exhausting fluid, and providing the exhaust channel with a control radius determined by the innermost radius of rotating fluid within the balance cavity as measured with respect to the centerline of rotation of the clutch assembly, the control radius being suitable for exhausting any excess of centrifugal balance force over centrifugal apply force.

    Abstract: A transmission includes first, second, third, and fourth clutches, first and second shift valves, and first, second, third, and fourth trim valves. Each trim valve is operative to control fluid pressure to a respective one of the first, second, third, and fourth clutches. The transmission also includes a controller. The controller is electrically operatively connected to the first and second shift valves and the first, second, third, and fourth trim valves to selectively provide a first clutch configuration for operating in a first mode and a second clutch configuration for operating in a second mode. The transmission also includes a clutch control mechanization for selectively moving to clutch configuration to a default position in the event power to the transmission is lost.

    Abstract: A fluid is supplied to a housing of a hybrid transmission. An overall system line pressure is elevated to induce leakage of the fluid through a control system. The leaked fluid is flowed through at least one backfill passage to the housing of the hybrid transmission. The leaked fluid is flowed over the motors disposed within the housing to cool the motors. The fluid that is flowed over the motors is collected to create a head pressure within the housing. The head pressure forces the collected fluid upwards within the transmission housing and into clutches that are disposed therein.

    Abstract: A hydraulic control system for a multi-mode hybrid-type power transmission is provided, including an engine-driven main pump in fluid communication with a main regulator valve, and an electrically driven auxiliary pump in fluid communication with an auxiliary regulator valve. A first pressure control solenoid is configured to provide boost pressure to the main regulator valve and thereby boost output of the main pump. A second pressure control solenoid is configured to provide boost pressure to the auxiliary regulator valve and thereby boost output of the auxiliary pump. The distribution of boost pressure from the pressure control solenoids is selectively modified such that at least one of the flows of pressurized fluid from the pumps is equal to the current line pressure requirements of the transmission during engine auto-start and auto-stop, and transitions thereto. An improved method for regulating the hydraulic control system is also provided.
