Abstract: A transmission includes a latch valve with latched and de-latched states. In the de-latched state, the latch valve directs a control pressure to a clutch apply circuit. In the latched state, which is entered in response to a control pressure higher than a latch pressure, the latch valve directs a line pressure to the clutch apply circuit. A controller manages the transition from latched to de-latched differently depending upon the transmission input torque and gear state. At high transmission input torque, the controller first reduces the control pressure to rapidly accelerate a spool in the latch valve, and then increases the control pressure to prevent clutch slip. At low torque, the controller reduced the pressure to an intermediate value during the transition and then reduces it again. At moderate torques, the controller reduces the pressure directly to a target pressure in a single step.

Abstract: A vehicle includes both a transmission park mechanism and an electronic parking brake. As a failure management strategy, a controller monitors vehicle movement to verify that the park mechanism is successfully restraining the vehicle against movement. Specifically, when the driver releases the brake pedal with the transmission park mechanism commanded to restrain the vehicle, the controller waits for a predetermined amount of time. If the vehicle moves during this time, the controller commands application of the electronic parking brake. The controller may also command application of the electronic parking brake if the vehicle does not come to a stop after the transmission park mechanism is commanded to restrain the vehicle.

Abstract: A motor vehicle includes a transmission having a control valve and a torque converter with a lock-up clutch. The control valve is configured to control both a mode and an apply pressure of the lock-up clutch. The control valve includes a valve body and a plunger moveable within the valve body. When the plunger is in a first position, the lock-up clutch is in a release mode and, when the plunger is in a second position, the lock-up clutch is in an apply mode and movement of the plunger relative to the second position controls the apply pressure.

Abstract: A vehicle includes a heat exchanger, a transmission, and a controller. The transmission is configured to transfer power within a powertrain. The transmission has a primary fluid circuit, a secondary fluid circuit, and a valve. The secondary fluid circuit is configured to divert the fluid from the primary fluid circuit and deliver the fluid to the heat exchanger. The valve is configured to control diverting fluid from the primary fluid circuit to the secondary fluid circuit. The controller is programmed to, in response to a temperature of the fluid being outside of a desired range, open the valve to direct the fluid toward the heat exchanger via the secondary fluid circuit. The controller is further programmed to, in response to the temperature of the fluid being within the desired range, close the valve to isolate the fluid from the secondary fluid circuit and the heat exchanger.

Abstract: A transmission includes a gearing arrangement configured to shift speed ratios by disengaging an off-going shift element and engaging an oncoming shift element and an electrohydraulic valve having an actuatable valve element configured to control an engagement state of the oncoming shift element. A controller is programmed to, during a shift of the transmission, in response to the off-going shift element disengaging and an expected ratio change not initiating, monotonically increase current to the valve to a maximum value to overcome frictional resistance on the valve element, and programmed to, in response to expiration of a timer and the ratio change still not initiating, send a repeating pattern of high and low current signals according to a duty cycle to overcome frictional resistance of the valve element.

Abstract: A park valve performs a multi-plexing function in which an out-of-park circuit is connected to line pressure when the valve is in an out-of-park position and is vented when the valve is in a park position. When particular clutches are released, the out-of-park circuit biases the park valve toward the out-of-park position. To initiate engagement of park, a controller commands a low line pressure, reducing the forces that bias the park valve toward the out-of-park position. Once the valve reaches an intermediate position in which the line pressure circuit is no longer fluidly connected to the out-of-park circuit, the controller commands an increase in line pressure, increasing the forces that bias the park valve toward the park position.

Abstract: A sliding vane pump includes a passageway that fluidly connects one or more pumping chambers to a side chamber. The passageway pressurizes the side chamber. This fluid pressure exerts a force that counteracts the force caused by pressure differences between the outlet pumping chambers and the inlet pumping chambers. At high speed, part of the side chamber is pressurized by the smallest volume outlet pumping chamber while another portion of the side chamber is pressurized by the largest volume outlet chamber. This results in a force counteracting an uncommanded displacement decrease of the pump.

Abstract: A hydraulic control system provides lubrication fluid to a gearbox via two flow paths in parallel. One of the flow paths includes a passive thermal valve in series with a heat exchanger. When the fluid temperature is elevated, the thermal valve opens such that fluid flows through the heat exchanger for cooling. The thermal valve restricts flow to the heat exchanger when transmission fluid is in a normal operating temperature range, reducing flow demands. When the flow demands are reduced, a variable displacement pump requires less torque improving fuel economy. The thermal valve may also open when the fluid is below the normal operating temperature such that the heat exchanger heats the fluid. The parallel path may include a regulator valve. When the pressure of fluid in the lubrication circuit is elevated, the regulator valve reduces flow through the parallel path and may also divert flow to a sump.
