Embodiment Construction

[0016] The following description is merely exemplary in nature and in no way restricts the invention and its application or uses. For purposes of clarity, the same reference numbers will be used in the drawings to identify similar elements. As used herein, the phrase at least one of A, B, and C should be taken to mean a logical (A or B or C) using a non-exclusive logical or. It should be understood that steps within a method may be executed in different order without altering the principles of the present disclosure.

[0017] As used herein, the term "module" refers to an Application Specific Integrated Circuit (ASIC), an electronic circuit, a processor (shared, dedicated or group) and memory that executes one or more software or hardware programs, Combinational logic circuits or other suitable components providing the described functionality.

[0018] The engine control system controls torque output. The accuracy of an engine control system depends in part on robust detect...

Abstract

An engine system includes a throttle actuator module and a torque control module. The throttle actuator module controls a throttle actuator based on a desired throttle area. The torque control module determines an actuator torque. The torque control module determines a rate limited torque, a maximum torque, and a minimum torque based on the actuator torque and a predetermined rate of change. The torque control module determines the desired throttle area based on the actuator torque when the rate limited torque is greater than the maximum torque. The torque control module determines the desired throttle area based on the actuator torque when the rate limited torque is less than the minimum torque.

Description

[0001] This application claims the benefit of US Provisional Application No. 61 / 099,638, filed September 24, 2008. The content of the aforementioned application is incorporated herein by reference. technical field [0002] The present invention relates to control of vehicle actuators to achieve a desired engine torque, and more particularly to ensuring conversion of the desired engine torque to a desired throttle area. Background technique [0003] The background description provided herein is for the purpose of generally presenting the context of the disclosure. What the inventors have described in this background section, and aspects of which, at the time of writing, would not otherwise be considered prior art, are neither specifically nor implicitly considered to be a violation of the prior art of the present invention. technology. [0004] Internal combustion engines combust an air and fuel mixture within cylinders to drive pistons, which produce drive torque. Air flo...
