Embodiment Construction

[0045] 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 interpreted logically, as using a non-exclusive logical "or" (A or B or C). It should be understood that various steps within a method may be executed in different order without altering the basic principles of the invention.

[0046] As used herein, the term "module" refers to an application-specific integrated circuit (ASIC), electronic circuit, processor (shared, dedicated, or grouped) and memory, combinational logic, and circuits, and / or other suitable components that provide the above functions.

[0047] now refer to figure 1 , a schematic block diagram of the vehicle 10 is shown in the figure. The vehicle 10 may include powertrain components such as a...

Abstract

A method and control module for operating a vehicle powertrain in response to a cruise control includes a primary closed loop control module generating a primary closed loop control signal and a primary torque request signal based on the primary closed loop control signal. The control module also includes a secondary closed loop control module generating a secondary closed loop control signal and a secondary torque request signal based on the secondary closed loop control signal. A transmission control module controls a transmission based on the primary torque request control signal and the secondary torque request signal.

Description

technical field [0001] The present invention relates generally to methods and systems for controlling engines and transmissions, and more particularly to methods and systems for controlling engines and transmissions in response to cruise control requests. Background technique [0002] The background description provided herein is for the purpose of generally presenting the context of the disclosure. To the extent described in this Background section, the work of the presently named inventors and aspects of this description that were not prior art at the time of filing are neither expressly nor implicitly admitted to be prior art to the present invention. [0003] Historically, cruise control systems have been integrated with a single closed loop control device including an integrator. An upper boundary condition is imposed on the closed-loop control to avoid integrator windup. The upper boundary condition is usually based on wide open throttle (WOT). To obtain the necessa...
