Abstract: A continuously variable transmission (CVT) includes input and output members, a primary variator pulley, and a secondary variator pulley. The respective variator pulleys are responsive to primary and secondary pressures. Speed sensors measure a respective rotational speed of each variator pulley. A controller executes a method by receiving the measured rotational speeds, calculating a current speed ratio of the CVT above a threshold CVT speed ratio using the rotational speeds, comparing the calculated current speed ratio to calibrated threshold ratios during a sudden stop event of the vehicle, and selectively executing a CVT control action after the calculated current speed ratio drops below the threshold CVT speed ratio during the sudden stop event. The control action depends on which of the threshold ratios is exceeded by the calculated current speed ratio after the calculated current speed ratio drops below the threshold CVT speed ratio, and on the measured rotational speeds.
