Appl. No.:

12/988813

Inventors:

Joseph F. Labataille - Royal Oak MI, US
Robert Keefover - Lake Orion MI, US
Matthew E. Junker - Cadillac MI, US

Assignee:

BorgWarner Inc. - Auburn Hills MI

International Classification:

F15B 13/12
G05B 11/01
F16K 31/02

US Classification:

25112904, 25112912, 318560, 318599

Abstract:

A method for controlling an actuator, such as the type used to drive valves, vanes, and other variable position devices. In one exemplary embodiment, a method may improve the accuracy of actuator feedback by periodically or dynamically resetting the position of a lower hard stop, which can then be used as a future point of reference.

Robert D. Keefover - Lake Orion MI, US

Assignee:

BorgWarner Inc - Auburn Hills MI

International Classification:

G05B 23/02
G05B 23/00

US Classification:

318565, 702105

Abstract:

The present invention is related to a method of controlling a device having a calibration process. The calibration process has a partial calibration routine and a calibration routine. A detector within the control system is capable of receiving one or more input signals and determining whether a partial calibration or calibration should occur. The first step in the process involves starting the control method where the detector receives input signals or generates it own data within the detector. The detector also determines whether a partial calibration routine or a calibration routine will take place based upon the value of the input signals received. A partial calibration routine will be performed if the input signals to the detector do not favor a calibration.

Abstract:

A method of controlling a device having restricted movement. A controller is provided for controlling the operation of the device using a control algorithm. A normal operation control method is programmed onto the controller and is selectively activated by the controller to generate a normal control signal. A forcing control method is also programmed into the controller and selectively activates a forcing control signal. The normal operation control signal provides regular operation of the device, while the forcing control signal causes the device to operate in a manner that will correct the operation of the device when a restricted motion of the device is detected.
