Abstract:
A control system includes an engine control module and a transmission control module. The transmission control module communicates with the engine control module via a network. The engine control module generates a mean engine speed signal and a minimum engine speed signal. The engine control module transmits the mean engine speed signal and the minimum engine speed signal to the transmission control module via the network. The transmission control module controls operation of at least one of a torque converter and a transmission based on the mean engine speed signal and the minimum engine speed signal. The torque converter is connected between an engine and the transmission.
