Abstract

The invention relates to the powertrain control systems and methods with parameter transfer between an ECM and a TCM. 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 transmission control module generates at least one of a back torque signal and a first engine acceleration signal. The transmission control module transmits the at least one of the back torque signal and the first engine acceleration signal to the engine control module via the network. The engine control module controls operation of an engine based on the at least one of the back torque signal and the first engine acceleration signal.

Description

technical field [0001] The invention relates to an engine and transmission control system including an engine control module and a transmission control module. More particularly, it relates to powertrain control systems and methods with parameter transfer between the ECM and TCM for ECM and TCM based control. Background technique [0002] The background description provided herein is for the purpose of generally presenting the context of the disclosure. To the extent that this background section describes the work of the presently mentioned inventors, and features of the invention that were not considered to be prior art at the filing date, no admission is made, either expressly or implicitly, to the present invention. have technology. [0003] Various engine control algorithms depend on timely estimates of engine speed. The engine control algorithms include direct algorithms, indirect algorithms, and / or diagnostic algorithms. Direct algorithms include determining parame...
