Abstract
Systems and methods are provided for controlling a transmission of a vehicle that has a selectable one-way clutch. 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.
