Appl. No.:

11/940693

International Classification:

G01P 3/481
G06F 19/00

US Classification:

701102, 123 9031

Abstract:

A method of correlating a rotational position of a crankshaft to a rotational position of a camshaft includes determining a stretch value of a timing connection, which drivingly couples the crankshaft and the camshaft, and calculating a crankshaft to camshaft rotational position value indicative of the rotational position of the crankshaft with respect to the rotational position of the camshaft. The crankshaft to camshaft rotational position value is compensated based on the stretch value to provide a compensated crankshaft to camshaft rotational position value and whether the rotational position of the crankshaft correlates to the rotational position of the camshaft is determined based on the compensated crankshaft to camshaft rotational position value.

Abstract:

An engine control system for a vehicle includes a variable displacement module that deactivates N of M cylinders of an engine during a fuel management mode. N is an integer and M is an integer greater than 1. A spark control module generates a spark timing signal for the N cylinders based on a pre-dwell time and a fuel management dwell modifier during the fuel management mode. The spark control module reduces dwell time of the N cylinders during the fuel management mode based on the fuel management dwell modifier.

International Classification:

F02D 41/30

US Classification:

701103

Abstract:

A system for an engine includes an edge detection module and a correlation calibration module. The edge detection module (i) detects edges of a camshaft of the engine using a camshaft position sensor, and (ii) detects edges of a crankshaft of the engine using a crankshaft position sensor. The correlation calibration module calibrates a correlation between the crankshaft and the camshaft based on the detected edges of the crankshaft and the camshaft, respectively.

International Classification:

G01B 714
G01B 730
G01B 700
F02P 7067

US Classification:

32420725

Abstract:

A method and apparatus for detecting an engine crankshaft angular position which provides for fast starting of the engine. A target wheel and sensor combination generate an analog signal which is convened into a 24 bit digital output which repeats every 360. degree. rotation of the crankshaft. Each bit represents a particular angular position of the crankshaft. Any 6 sequential bits in the repeating 24 bit digital output sequence form a unique pattern. By monitoring the first six bits generated (90. degree. of crankshaft rotation) during startup, a crankshaft angular position can be determined, thereby enabling fast starting of the engine.

International Classification:

G01B 730
G01P 3489
F02P 7067
H03M 122

US Classification:

32420721

Abstract:

A rotation sensor includes a binary encoded target wheel and a pair of sensors disposed about the target wheel periphery. One of the sensors provides a signal indicative of the passage of regular angular intervals of the target wheel and the other of the sensors provides binary states corresponding to the regular angular intervals.
