Embodiment Construction

[0086] The following description is merely exemplary in nature and is not intended to limit the invention, its application or uses in any way. For purposes of clarity, the same reference numbers will be used in the drawings to designate similar elements. As used herein, the phrase at least one of A, B, and C should be understood as a logical (A or B or C) using a non-exclusive logical or. It should be understood that various steps within a method may be executed in different order without altering the basic principles of the invention.

[0087] As used herein, the term "module" means (or forms part of or includes) an Application Specific Integrated Circuit (ASIC), electronic circuit, processor (shared, dedicated, or group) and memory, combinational logic circuits, and / or other suitable elements that provide the described functionality.

Abstract

The invention relates to shift sequencing systems for a dual clutch transmission, specifically to a dual-clutch transmission (DCT) shift sequencing system includes a shift type module that determines a shift type based on a scheduled gear and a current attained gear of a DCT. A shift sequence module determines a sequence index based on the shift type. A sequencing module generates a fork command signal and a clutch command signal based on a first sequencing table corresponding to the sequence index. A shift abort module may be included to terminate an ongoing shift and to transition to an updated shift. A fork control module controls fork shifting in the DCT based on the fork command signal. A clutch control module controls clutch engagement in the DCT based on the clutch command signal.

Description

technical field [0001] The invention relates to a dual clutch transmission control system. Background technique [0002] The background description provided herein is to generally describe the context of the disclosure. To the extent described in this Background section, the work of the presently named inventors, and those aspects of that description that may not have constituted prior art at the time of filing, are neither expressly nor implicitly considered to be part of the invention current technology. [0003] A manual transmission drivetrain includes an internal combustion engine (ICE), a clutch, and a manual transmission. The clutch engages the flywheel on the ICE and transfers the engine's torque output to the manual transmission. Torque transfer from the ICE to the transmission is interrupted when the vehicle operator manually shifts between gears of the transmission. During a shift event, the clutch is disengaged (ie, the ICE is disengaged from the transmission...
