Method And System For Detecting The Misfire Of A Reciprocating Internal Combustion Engine Utilizing A Misfire Index Model
US Patent:
5576963, Nov 19, 1996
Filed:
Oct 18, 1994
Appl. No.:
8/324596
Inventors:
William B. Ribbens - Ann Arbor MI
Jaehong Park - Seoul, KR
Jaehong Park - Seoul, KR
Assignee:
Regents of the University of Michigan - Ann Arbor MI
International Classification:
G01M 1500
US Classification:
36443108
Abstract:
A misfire index model-based method and system for detecting misfire in a reciprocating internal combustion engine having an engine cycle frequency in the frequency domain from crankshaft angular velocity. The misfire index model is a function of engine operating condition such as engine load and RPM. Crankshaft angular position is sensed to develop an electrical signal which is a function of the crankshaft angular velocity. The electrical signal contains data which is sampled. The sampled data is transformed to an equivalent frequency domain spectrum including frequency components of the engine cycle frequency and harmonics thereof. A load signal such as mass airflow and an RPM signal are generated. The magnitudes and/or phases of the frequency components and the load and RPM signals are supplied to the misfire index model in an appropriately programmed computer to distinguish between a true misfire and normal cyclic variability which characterizes the combustion process.
Method And System For Detecting The Misfire Of An Internal Combustion Engine Utilizing Angular Velocity Fluctuations
US Patent:
5239473, Aug 24, 1993
Filed:

Appl. No.:
7/741338
Inventors:

Assignee:
Regents of the University of Michigan - Ann Arbor MI
International Classification:
G01L 300
US Classification:
36443108
Abstract:
A hybrid method and system are disclosed for the detection of internal combustion engine misfires. The method and system are capable of detecting misfires even at very low occurrence rates in real time with inexpensive analog and digital (i. e. hybrid) electronics suitable for use on-board a vehicle, thus satisfying current and proposed exhaust emission control regulations. The method and system exploit a measurement of engine crankshaft angular velocity in conjunction with hybrid electronic signal processing. Once the angular velocity signal is conditioned to minimize the effects of random error and external disturbances, four alternate computationally efficient methods may be used to extract information pertaining to individual cylinder torque productions. Two of the methods employ extremal samples of the estimated torque or velocity waveform to obtain a random torque nonuniformity index or metric. The other two methods utilize a transformation into the frequency domain after the input data is first sampled and windowed to substantially lower probability of error.

International Classification:

US Classification:
3644241
Abstract:
An improved method and system are provided for the detection of internal combustion engine misfires utilizing optimum signal processing. The method and system exploit a measurement of engine crankshaft angular velocity in conjunction with hybrid electronic signal processing. Once the angular velocity signal is conditioned to minimize the effects of random error and external disturbances, four alternate computationally efficient methods may be used to extract information pertaining to individual cylinder torque productions. Two of the methods employ extremal samples of the estimated torque or velocity waveform to obtain a random torque nonuniformity index or metric. The other two methods utilize a transformation into the frequency domain after the input data is first sampled and windowed to substantially lower probability of error. All of the methods provide an M-dimensional torque non-uniformity vector of individual cylinder performance for each individual engine cycle. A reference level for the nonuniformity index is derived for any given cylinder in any given cycle.

Ronald J. Fredricks - Grand Rapids MI, US
International Classification:
B60T 8/86
US Classification:
303112, 303126
Abstract:
Improved anti-lock brake systems (ABS) employed on aircraft and land vehicles and methods of operating same employing a sliding mode observer (SMO) incorporated into an ABS algorithm requiring only measurement of wheel speed to regulate the application of braking torque are disclosed. Braking is optimized simply by maintaining an SMO estimate of differential wheel torque (road/tire torque minus applied brake torque) derived from wheel speed at an extremum via applying or releasing the brakes as the extremum is passed through.

Driveline Control System
US Patent:
4606005, Aug 12, 1986
Filed:
Feb 15, 1983
Appl. No.:
6/466745
Inventors:
William B. Ribbens - Ann Arbor MI
Assignee:
Borg-Warner Corporation - Chicago IL
International Classification:
G05D 1702, B60K 4104, G06F 1520
US Classification:
36443101
Abstract:
An engine transfers torque through a transmission to a load, and the torque transfer through the system is measured. From the torque measurement maximum and minimum amplitude torque signals are taken, to provide an indication of torque non-uniformity. These signals are then used to control engine operation to avoid a rough-running condition.
