Abstract

The present invention relates to a powertrain control system and method having an ECM to TCM parameter transfer protocol for TCM based control. Specifically, a control system is provided that includes an engine control module and a transmission control module. The TCM communicates with the ECM via the network. The engine control module generates an intermediate engine speed signal and a minimum engine speed signal. The engine control module transmits the intermediate engine speed signal and the minimum engine speed signal to the transmission control module via the network. A transmission control module controls operation of at least one of a torque converter and a transmission based on the intermediate engine speed signal and the minimum engine speed signal. A torque converter is connected between the engine and the transmission.

Description

technical field [0001] The present invention relates to an engine and transmission control system including an engine control module and a transmission control module. Background technique [0002] The background description provided herein is for the purpose of generally presenting the context of the disclosure. A portion of the work of the presently named inventors is described in the Background section, and aspects of this, and aspects of this description that were not otherwise prior art at the time of filing the application, are neither expressly nor impliedly admitted to defeat the prior art of the present invention. have technology. [0003] An automotive powertrain can include an engine, a torque converter, and a transmission. The torque converter includes an engine side, a transmission side, and an electronically controlled capacity clutch (ECCC). A torque converter converts engine output torque into transmission input torque. The transmission control module is ...
