    摘要: A mode selector mechanism for a selectable one way clutch assembly includes a lever moveable between a first position, a second position and a third position. A lever biasing device biases the lever in a first direction. A piston acts in opposition against the lever biasing device to move the lever in a second direction opposite the first direction. The piston is actuated by a variable hydraulic signal. The lever is disposed in the second position when the variable hydraulic signal includes a fluid pressure between a first fluid pressure and a second fluid pressure. The lever is disposed in the third position when the variable hydraulic signal includes a fluid pressure greater than the second fluid pressure. The lever is disposed in the first position when the variable hydraulic signal includes a fluid pressure less than the first fluid pressure.

    摘要: A method for controlling a powertrain includes monitoring engagement status of said selectable one-way clutch, monitoring an upshift command, monitoring a speed of an engine to torque converter shaft, monitoring a speed of a torque converter to transmission shaft, when the monitoring detects engagement of the selectable one-way clutch and the upshift command, then determining a relative rotational speed of the torque converter based upon the speed of said engine to torque converter shaft and the speed of said torque converter to transmission shaft. A locked selectable one-way clutch condition is diagnosed based upon the relative rotational speed. A torque increase is commanded from the engine based upon the locked selectable one-way clutch condition. And disengagement of the selectable one-way clutch is commanded.

    摘要: A transmission has four planetary gear sets, four interconnecting members and six torque-transmitting mechanisms selectively engageable in different combinations of three to establish at least eight forward speed ratios. A first of the six torque-transmitting mechanisms is selectively engageable to connect the second member of the first planetary gear set to the stationary member. A second of the six torque-transmitting mechanisms is selectively engageable to connect the input member for common rotation with the second member of the third planetary gear set. At least one of the first and the second of the six torque-transmitting mechanisms is a selectable one-way clutch configured to have a first operating mode and a second operating mode, either of which modes may be selected.

    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 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 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.
