Abstract
A voting strategy is used to determine the mode state of a transmission when a vehicle is restarted. A Powertrain Control Module, a Transmission Range Control Module, and a Gear Shift Module communicate through a communication network during execution of the voting strategy. Each module stores a remembered mode state (Normal, Neutral Hold, Neutral Tow, etc.) of the transmission in non-volatile memory. Upon module initialization, the Powertrain Control Module will compare its own remembered mode state of the transmission with the remembered mode state reported by the other two modules. A basic voting strategy is that if two of the three modules report the same remembered mode state then the Powertrain Control Module changes the transmission to that same mode state.
