System And Method For Dynamic Solenoid Response Adjust Control
US Patent:
8038076, Oct 18, 2011
Filed:
Jan 22, 2008
Appl. No.:
12/017665
Inventors:
Andrew D. Herman - Grand Blanc MI, US
Michael A. Kozan - Canton MI, US

Assignee:
Delphi Technologies, Inc. - Troy MI
International Classification:
G05D 23/02
G05D 23/12
G05D 23/12
US Classification:
236 93R, 137 2, 137 12, 137468
Abstract:
A method is described for controlling a solenoid-operated fluid valve having an output hydraulic pressure that varies in accordance with an input solenoid control current delivered from a drive circuit. A model is provided characterizing the plant dynamics of the solenoid-operated fluid valve and the drive circuit where the model is dependent on at least one operating parameter. The method, during operation, involves measuring the value of the operating parameter and adjusting based on the measured operating parameter value one or more gain constants to be used in a selected control strategy. The model is used in adjusting the gains. Finally, the method involves determining a required solenoid control current according to the control strategy with the now dynamically-adjusted gain constants. The control strategy may be a PI control strategy. The model-based system allows easy migration of the general control strategy to different hardware configurations by developing target system specific data for the model.
Cam Phasing System With Mid-Range Engine Shutdown
US Patent:
2007025, Nov 1, 2007
Filed:
May 1, 2006
Appl. No.:
11/415333
Inventors:
Daniel Gauthier - Clarkston MI, US
Michael Kozan - Canton MI, US
John Waller - Ann Arbor MI, US
Daniel Moreno - El Paso TX, US
Sergio Quelhas - Ann Arbor MI, US

International Classification:
F01L 1/34
US Classification:
123090170
Abstract:
A camshaft phaser system includes an oil control spool valve having two opposing springs to center the spool at a rest position to lock the phaser rotor by blocking supply/vent to both the Cand Cchambers, obviating a conventional locking pin mechanism. A double-acting solenoid actuator moves the spool to first and second positions, supplying or venting Cand Crespectively. The rotor may be locked hydraulically at any position between full advance and full retard. A system for monitoring the rotational positions of the crankshaft and camshaft includes magnets disposed on opposite sides of the shaft axis. A magnetic sensing element senses the rotational direction of the magnetic field for each position of the shaft. An engine control module uses the position signal and an algorithm to lock the rotor at a desired position.

International Classification:
G01B 7/30
US Classification:
3242072, 32420725
Abstract:
A camshaft phaser system includes an oil control spool valve having two opposing springs to center the spool at a rest position to lock the phaser rotor by blocking supply/vent to both the C1 and C2 chambers, obviating a conventional locking pin mechanism. A double-acting solenoid actuator moves the spool to first and second positions, supplying or venting C1 and C2, respectively. The rotor may be locked hydraulically at any position between full advance and full retard. A system for monitoring the rotational positions of the crankshaft and camshaft includes magnets disposed on opposite sides of the shaft axis. A magnetic sensing element senses the rotational direction of the magnetic field for each position of the shaft. An engine control module uses the position signal and an algorithm to lock the rotor at a desired position.
