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 method for preventing a torque converter clutch that controls the slip in a torque converter between a vehicle engine and transmission from locking up in response to wheel slip from one or more of the vehicle wheels. The method includes monitoring the vehicle speed and/or the transmission output speed, and converting the speed to an acceleration. An average of the acceleration is provided over a predetermined number of sample points. The method then determines whether the current acceleration exceeds the average acceleration by a predetermined amount. If the current acceleration does exceed the average acceleration, then the method causes the converter slip to be held at its current value so that the torque converter does not lock up. Additionally, the method prevents the transmission from changing gears. The method then monitors whether the acceleration has fallen below a predetermined value or a predetermined period of time has expired.

摘要： A method for controlling a torque converter having an internal lockup clutch includes detecting vehicle operating conditions and executing one of a stored plurality of torque converter clutch modes each corresponding to a different set of vehicle operating conditions. A fully-released mode corresponds to vehicle pre-launch, a partially-engaged mode corresponds to post-launch of the vehicle in first gear, downshift, coasting, throttle tip-in, or throttle tip-out; a first fully-engaged mode corresponds to steady-state operation in second gear or a higher; and a second fully-engaged mode corresponds to an upshift. Slippage across the converter is controlled only during the first fully-engaged mode. A vehicle is also provided having an engine, transmission, torque converter with lockup clutch, and controller having a control algorithm. The algorithm executes a different lockup clutch mode based on the detected vehicle operating conditions, and the slippage across the converter is controlled during only one lockup clutch mode.
