    摘要: A method optimizes a fill event of an apply chamber of a fluid-actuated clutch, and includes determining input values describing the fill event, and then estimating a fill time using the input values. The method includes filling the apply chamber using the estimated fill time (EFT) or within an allowable range of the EFT. The input values can include a command line pressure, command fill stroke pressure, and an estimated viscosity of the fluid, although other values can be used. The input values are processed through a neural network having an input layer, an optional hidden layer, and an output layer. An assembly includes a fluid-actuated clutch having an apply chamber and a controller operable for estimating the fill time required for filling the apply chamber, and for controlling the fill of the apply chamber within the EFT.

    摘要: A vehicle includes an automatic transmission having an engine, an input member, a stationary center support, and a selectable one-way clutch (SOWC) positioned within the stationary center support. A SOWC selection mechanism is formed integrally with the center support, and rotates a slide plate during a predetermined transmission operating mode. A piston in a first bore of the selection mechanism rotates the slide plate in a first rotational direction to engage the SOWC, and a return spring in a second bore of the selection mechanism rotates the SOWC in a second direction to disengage the SOWC. The slide plate has a tab portion, and the piston and the return spring alternately apply a respective first and second force to opposite sides of the tab portion to rotate the slide plate, either directly or via an adapter ring.

    摘要: A multi-speed transmission for a vehicle is provided with a selectable one-way braking clutch (SOWBC). The transmission has an input member connected for common rotation with one of the members of four planetary gear sets and an output member connected for common rotation with another of the members of the planetary gear sets. Four interconnecting members connect different members of the planetary gear sets for common rotation. A first brake is selectively engagable to ground the first member of the first planetary gear set to the stationary member. A first, a second, and a third rotating clutch are each selectively engagable to connect a different respective pair of the members of the planetary gear sets for common rotation. A selectable one-way braking clutch is configured to brake in one rotational direction and is selectively reversible to brake in an opposite rotational direction, and freewheels in some speed ratios.

    摘要: A system and method for setting the slip of a torque converter for a plurality of selected engine speeds and transmission gears. The method includes populating a table off-line, typically using a dynamometer, with torque converter slips for a plurality of selected engine speeds and transmission gears. A speed sensor is used to measure vibrations transmitted through the torque converter to the driveline of the vehicle. The sensor signal is sent to an analyzing system where it is converted to the frequency domain. A separate minimum slip value for each selected engine speed and transmission gear is stored in a table so that during vehicle operation, a controller will instruct the torque converter clutch to set the desired converter slip for the current engine speed and transmission gear provided for a particular throttle position and/or engine torque.

    摘要: A powertrain in a vehicle includes an electro-mechanical transmission having a selectable one-way clutch mechanically-operatively coupled to an internal combustion engine and configured to selectively transmit mechanical power to an output member. A control method includes monitoring a vehicle speed, monitoring a transmission gear state, comparing the vehicle speed to a threshold low speed range, transitioning a selectable one-way clutch into an engaged mode when said vehicle speed is not in a forward direction in excess of the threshold low speed range, and maintaining the selectable one-way clutch in the engaged mode based upon the transmission gear state remaining in a first gear state and the vehicle speed remaining within said threshold low speed range, a neutral state, or a reverse state.

    摘要: A vehicle includes a rear-wheel drive (RWD) automatic transmission having a stationary member, a two-mode selectable one-way clutch (SOWC), pressurized fluid, and a valve body assembly (VBA). The VBA has a piston, a return spring, and an actuator linkage in contact with the piston and a shift lever of the SOWC. Fluid moves the piston and linkage in one direction to lock the SOWC and enable a reverse mode having no spin losses, and the spring moves the piston and linkage in another direction to unlock the SOWC in a forward mode. A method reduces spin losses by admitting fluid into the VBA to move the piston in one direction to thereby rotate the shift lever of the SOWC to one angular position to lock a driving member of the transmission to the stationary member during reverse, engine braking first gear, and manual low speeds.

    摘要: A vehicle includes a front-wheel drive (FWD) transmission having a case, a selectable one-way clutch (SOWC) indexed to the case, pressurized fluid, and a valve body assembly (VBA). The VBA has a piston in communication with the fluid, a return spring, and an actuator plate in continuous contact with or connected to each of the piston and a shift lever of the SOWC. Fluid moving the piston and plate in one direction locks the SOWC to enable a reverse mode, and the spring moves the piston and the plate in another direction to unlock the SOWC in a forward mode. A method prevents spin losses in the FWD transmission by positioning a two-mode SOWC within a case, positioning a VBA adjacently and externally to the case, and admitting pressurized fluid into the VBA to engage the SOWC only during a reverse operating mode.
