    Abstract: A variable force solenoid valve and a switching valve provide minimal line pressure disturbance in the output of an engine driven balanced hydraulic pump when switching between full flow and half flow in an automatic transmission. The variable force solenoid receives a signal from a transmission control module (TCM) or other electronic controller and provides controlled, pressurized hydraulic fluid (transmission oil) to a modulating binary switching or control valve that in a first position provides fluid flow from both outlet ports of the hydraulic pump to the line pressure regulator, modulates to reduce pressure and flow by returning a portion of the flow from one output port to an inlet port to match the requirements of the transmission between the first position and a second position and, in the second position, returns all flow from one of the pump outlet ports back to a suction or inlet port of the pump

    Abstract: A vehicle includes an engine, a transmission with a shift valve, an alternator, an auxiliary battery, a voltage sensor operable to measure an auxiliary voltage, and an electronic transmission range selection (ETRS) system. The ETRS system includes a controller, and also an electronic range selector device that transmits an electronic range request signal to the controller to request the shift of the transmission to a requested operating range. The controller executes a method to predict a loss of auxiliary power aboard the vehicle, and to control an action of the vehicle in response to the predicted loss of auxiliary power. The electronic range request signal is received from the range selector device and auxiliary voltage. The controller calculates a slope of a decrease in the measured auxiliary voltage. A control action is executed with the alternator is in the charging state and the calculated slope exceeds a calibrated slope threshold.

    Abstract: A vehicle includes an engine, first clutch, transmission, and controller. The transmission includes a gearbox, position sensors, and a fluid circuit. The gearbox contains a second clutch. The fluid circuit includes a pump and a flow control solenoid valve. The controller opens the valve via flow control signals to allow fluid to pass into or from the particular clutch it feeds. The controller executes steps of a method to determine an actual flow rate through the valve as the clutch moves, and also calculates a compensation scale factor as a ratio of the commanded and actual flow rates. The controller modifies the flow control signals in a subsequent clutch actuation using the compensation scale factor, such as by multiplying a commanded flow rate corresponding to the flow control signals by the compensation scale factor. A system includes rotatable members connected by a clutch, the controller, valve, and position sensor.

    Abstract: A hydraulic circuit for a hybrid powertrain having an engine and an electric motor. The hydraulic control circuit includes a first pressure regulating valve configured to cooperate with a shift valve for selectively communicating a hydraulic fluid to a hydraulic piston actuator of a clutch assembly for engaging the engine to a driveline. The hydraulic control circuit further includes a second pressure regulating valve configured to selectively communicate a flow of hydraulic fluid to a cooling circuit for the cooling of the electric motor and to cooperate with a check valve and the shift valve to actuate the hydraulic piston actuator during a predetermined fail mode of the first pressure regulating valve, thus providing a limp-home mode by coupling the torque output from the engine to driveline of the vehicle.
