Abstract:
A voting strategy is used to determine the mode state of a transmission when a vehicle is restarted. The transmission includes a return to park feature and a controller including at least three memories. The controller is configured to write a remembered mode state into each memory. The remembered mode state is one of a Normal mode state that allows the transmission to automatically shift to Park, a hold mode state that causes the transmission to remain in Neutral and not automatically shift to Park upon detecting a triggering event or other mode states. The controller reads each memory and, when at least two of the remembered mode states are the same mode state, causes the transmission to enter a mode state corresponding to the same mode state.
