The system includes a sensor system, an anti-lock brake system (ABS), and a controller configured to, by a processor: monitor for a deceleration event wherein an estimated output speed acceleration of the vehicle is reduced below a first threshold, receive a status of the ABS, and output one or more control signals to command the transmission to inhibit the application of the selectable one-way clutch in response to detection of the deceleration event when the selectable one-way clutch is not applied, and the estimated output speed acceleration of the vehicle is either: (i) below the first threshold while the anti-lock brake system ABS of the vehicle is active, or (ii) below a second threshold while the ABS is inactive, wherein the first threshold is greater than the second threshold.

Abstract: A system includes a clutch control module, a shift control module, and a torque control module. The clutch control module is configured to generate a release command signal to switch a selectable one-way clutch (SOWC) from a locked state to a freewheel state. When the SOWC is in the locked state, a transmission transfers torque from an engine to a driveline and from the driveline to the engine. When the SOWC is in the freewheel state, the transmission transfers torque from the engine to the driveline and but not from the driveline to the engine. The shift control module is configured to generate a shift command signal to shift the transmission from a first gear to a second gear after the release command signal is generated. The torque control module is configured to increase an output torque of the engine for a period when the shift command signal is generated.

Abstract: A method for controlling internal electronic range selection for an automatic transmission includes: confirming if a range change command has been ordered from a current transmission operating state; verifying expected performance from at least first and second mode valves and a park servo are present in the current transmission operating state prior to allowing a range change event; during the range change event: generating proactive commands including ordering a reduction in a hydraulic system pressure; and identifying if an unexpected event is detected; and following completion of the range change event confirming expected performance is obtained from at least the first and second mode valves and the park servo to achieve a driver intended state.

Abstract: A transmission includes a stationary member, an input member, and gear sets each having a plurality of nodes. The transmission includes a first clutch that connects a node of one gear set to the stationary member to establish an L1 mode, and a second clutch that connects a node of another gear set to the stationary member to establish a 2L mode. A SOWC is connected between nodes of two gear sets, and a controller, in response to a requested shift L1-L2 shift while engine braking, executes a method to release the first clutch and thereby enters a neutral mode. The SOWC is released when slip across the first clutch exceeds a first threshold, then the first clutch reapplied when a SOWC slip level exceeds another threshold to thereby enter a 1st gear freewheeling mode. The second clutch is reapplied to enter the L2 mode and resume engine braking.

Abstract: A system for determining when a selectable one-way clutch has mechanically released includes an update timer identifying if each of a converter model engine torque, a transmission input torque, and a torque converter slip are positive for a predetermined period of time. An SOWC slip value is calculated using an output signal from each of: at least one transmission internal speed sensor producing an output signal representative of a speed of an internal component of a transmission; and at least one transmission output speed sensor producing an output signal representative of a speed of an output of the transmission. An SOWC released signal is issued if either all of the measured converter model engine torque, the measured transmission input torque, and the measured torque converter slip are positive for at least the predetermined period of time, or the calculated SOWC slip value is greater than a predetermined threshold.

Abstract: A vehicle includes an engine, a dry dual-clutch transmission (dDCT) having a pair of input clutches and a gearbox containing oddly- and evenly-numbered gear sets, and a transmission control module (TCM). Application of one of input clutches connects the engine to a corresponding one of the oddly- or evenly-numbered gear sets. The TCM includes feed-forward PID-based control logic, and a torque-to-position (TTP) table for each input clutch. The TCM commands a position of a designated input clutch during a power-on upshift using the feed-forward, PID-based control logic, and selectively adapts the TTP table as a function of an inertia and acceleration value of the engine. The TCM may apply an asymmetrical handoff profile to commanded oncoming and offgoing clutch torques during the torque phase of the upshift. The TCM may also adjust the TTP table as a function of the frequency of use of the input clutches.

Abstract: An intermediate service provider operates to mediate communications between mobile terminals and various service providers. In one embodiment, the intermediate service provider and a given mobile terminal establish a persistent session supported by a logical communication channel that is used to convey communications for all of the various service applications implemented by the mobile terminal, i.e., a single, multiplexed channel. In another embodiment, common command subsystems are used to support the multiple service applications, thereby reducing overhead resulting from multiple protocol headers. In yet another embodiment, establishment of communications with various service providers begins with a single connection request message that specifies at least two selected service applications such that the intermediate service provider can establish communications with the multiple service providers in response to the single connection request message.
