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 vehicle transaxle includes a housing, an electric machine, and rotating components. The housing defines an internal cavity, a first channel, and a second channel. The first and second channels branch from a common inlet. The electric machine and rotating components are disposed within the internal cavity. The first channel is configured to deliver fluid to the electric machine for cooling. The second channel is configured to deliver the fluid to the rotating components for lubrication. The cooling channel is sized relative to the lubrication channel such that the fluid is biased from the inlet and toward the second channel in response to a temperature of the fluid being less than a threshold and is biased from the inlet and toward the first channel in response to the temperature of the fluid being greater than the threshold.

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 hydraulic boost valve includes a housing, a valve seat, and a piston. The housing defines an axially extending internal cavity, a slot that extends radially outward from the internal cavity within the housing, and an outlet port that establishes fluid communication between the slot and a fluid output circuit. The valve seat is secured to an end of the housing. The valve seat defines first and second orifices. The first orifice establishes fluid communication between a fluid input circuit and the outlet port via the slot. The second orifice establishes fluid communication between the fluid input circuit and the fluid output circuit. The piston is disposed within the internal cavity such that the slot is positioned between the piston and an external wall of the housing.

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 engage park, a controller commands a low line pressure, reducing the forces that bias the park valve toward the out-of-park position. To accelerate the pressure decay in the line pressure circuit, thereby decreasing the time required to achieve park, the controller commands engagement of one or more shift elements.

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: In order to pre-stage a clutch piston in preparation for clutch engagement, a controller commands a high current to a Casting Integrated Direct Acting Solenoid (CIDAS) valve. This staging is performed in two distinct phases wherein the current is higher in the first phase than in the second phase. Staging the piston in this manner reduces the staging time and reduces the variability of the staging time. The duration of the first phase may be adjusted based on a number of parameters including, the length of a preceding engine off period, the number of clutch applications since the engine off period, a fluid temperature, and a length of time since a preceding engagement of the clutch.

Abstract: An automatic transmission uses 6 shift elements applied in combinations of four to establish ten forward speed ratios and a reverse speed ratio. The automatic transmission uses a hydraulic control system to control engagement of the six elements, control engagement of a torque converter bypass clutch, control engagement of a parking pawl, and to provide fluid for a hydrodynamic torque converter and for lubrication. The parking pawl is disengaged in response to engagement of two of the six shift elements and remains disengaged in response to engagement of other shift elements. A single valve controls several different functions associated with the two-pass torque converter. Pressurized fluid is provided by a variable displacement engine driven pump and also by an electric pump. A priority valve reduces lubrication flow when other fluid demands are high as indicated by the pump displacement control circuit.

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.
