摘要： 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.

摘要： An actuator apparatus includes an oil passage body including an oil passage therein, an electric actuator, a movable unit moved at least in a first direction and a second direction by the electric actuator, and an auxiliary device including an actuating member moved by hydraulic pressure of oil in the oil passage. When the electric actuator moves the movable unit in the second direction, the auxiliary device applies, through the actuating member to the movable unit, a force pointing in a direction that moves the movable unit in the second direction.

摘要： A vehicle including a transmission and an electronic transmission range selector system in communication with the transmission to shift the transmission to one of a park operating position and an out-of-park operating position. A clutch is movable between an engaged position grounding a portion of a planetary gear set to a transmission casing to operate the gear set in a first gear and a disengaged position. A first pawl is movable between a first position to mechanically couple the first pawl to the portion of the planetary gear set when the clutch is in the disengaged position such that the first pawl operates the gear set in the first gear, and a second position to mechanically decouple the first pawl from the portion of the gear set when the clutch is in the engaged position such that the clutch operates the planetary gear set in the first gear.

摘要： A motor vehicle transmission is disclosed. The transmission includes at least ten gear-selection pressure chambers which are provided for the selection of a plurality of transmission gears, at least two actuation valves, each of which is provided for setting at least one actuation pressure for the gear-selection pressure chambers, at least one first selection valve unit, at least one second selection valve unit, and at least one third selection valve unit which are provided for connecting the actuation valves to the gear-selection pressure chambers. The second selection valve unit is directly connected to four gear-selection pressure chambers in order to transmit actuation pressure and the third selection valve unit is directly connected to six other gear-selection pressure chambers and directly to the second selection valve unit in order to transmit actuation pressure.

摘要： A device includes a switching valve that performs switching between a first state of supplying a line pressure to an oil chamber defined by a case and a piston and a second state of discharging (draining) hydraulic oil in the oil chamber. The device also includes a drain check valve that closes (prohibits the hydraulic oil in the oil chamber from being discharged) when the line pressure is supplied to the oil chamber, and opens (allows the hydraulic oil in the oil chamber to be discharged) when the line pressure is not supplied to the oil chamber. The hydraulic oil is discharged from the oil chamber through the switching valve and the drain check valve.
