20080300747 | REAL TIME TRANSMISSION SHIFT QUALITY DETECTION AND EVALUATION UTILIZING TRANSMISSION OUTPUT SHAFT ACCELERATION - A shift quality error detection system for an automatic transmission includes a vehicle acceleration determination module to determine a vehicle acceleration. An acceptance window module defines upper and lower limits of a desired vehicle acceleration. The shift quality error detection module compares the determined vehicle acceleration to the upper and lower limits of the desired vehicle acceleration. A shift quality error detection module selectively provides a shift quality error based on the comparison. A method of detecting shift quality error of an automatic transmission comprises determining a vehicle acceleration during a transmission gear shift. The method also includes comparing the vehicle acceleration to an acceptance window of desired vehicle accelerations and outputting an error signal based on the acceleration comparison. | 12-04-2008 |

20080201032 | VEHICLE DIAGNOSTIC CODE COMMUNICATION DEVICE AND A METHOD FOR TRANSMITTING DIAGNOSTIC DATA UTILIZING THE VEHICLE DIAGNOSTIC CODE COMMUNICATION DEVICE - A vehicle diagnostic code communication device and a method for transmitting diagnostic data utilizing the vehicle diagnostic code communication device are provided. The vehicle diagnostic code communication device includes a diagnostic link connector configured to receive signals indicating a diagnostic code associated with vehicle operation and a microprocessor operably coupled to the diagnostic link connector. The microprocessor is configured to determine at least one of diagnostic textural data and diagnostic audio data based on the diagnostic code and to induce an RF transmitter to transmit a first RF signal having at least one of the diagnostic textual data and the diagnostic audio data. | 08-21-2008 |
20080288154 | System for discrimination of spurious crank encoder signals - A system for discrimination of spurious crankshaft encoder signals. A position encoder connected to an engine crankshaft sends a pulsed signal indicative of crankshaft rotational performance to an engine controller. The controller is programmed to trigger an interrupt service routine (ISR) on every falling or rising edge of each pulse. The ISR calculates and stores the period of each pulse and the period of the previous pulse and calculates the rotational speed and instantaneous acceleration or deceleration of the engine at all times. The controller is further programmed with realistic engine acceleration and deceleration limits and recognizes a next signal only within a time window corresponding to those limits and the engine speed. Signals arriving outside the calculated time window are considered spurious and are rejected. The system improves engine performance by preventing loss of synchronization between spark and fuel injection and piston and valve timing. | 11-20-2008 |
20100130160 | VEHICLE EMERGENCY COMMUNICATION DEVICE AND METHOD FOR UTILIZING THE VEHICLE EMERGENCY COMMUNICATION DEVICE - A vehicle emergency communication device and a method of utilizing the device are provided. The device includes a portable housing having a first diagnostic link connector, a microprocessor, and an RF transmitter disposed therein. The first diagnostic link connector is configured to be removably connected to a vehicle communication bus, and is further configured to receive a signal indicating deployment of a vehicle airbag from the vehicle communication bus. The microprocessor is configured to induce the RF transmitter to transmit an RF signal having an emergency call message therein in response to receiving the signal from the first diagnostic link connector. The emergency call message has data for inducing a cellular phone receiving the RF signal to further communicate with an emergency call center computer. | 05-27-2010 |

20130269415 | CRANK SIGNAL ERROR DETECTION USING A CAM SIGNAL INTERVAL - A method of detecting a crank signal error that includes incrementing a crank tooth counter in response to detecting a crank signal, comparing the crank tooth counter to an expected value when a cam signal is detected, and indicating a crank signal error if the crank tooth counter is not substantially equal to the expected value. This method is advantageous because a cam interval used to determine when to start and stop counting crank tooth pulses is automatically adjusted for variations in engine speed, while the prior art time based methods must adjust the time interval for variations in engine speed. | 10-17-2013 |
20130275022 | ENGINE CRANK SIGNAL CORRECTION METHOD AND CONTROLLER - An engine control module and method configured to correct an engine crank sensor signal for errors in an apparent location of a tooth edge on a crank wheel is provided. A correction factor is determined based on a first formula if a comparison of adjacent pulse intervals to predetermined thresholds indicates that a tooth edge appears to be abnormally late, and determined based on a second formula if a comparison of adjacent pulse intervals to other predetermined thresholds indicates that a tooth edge appears to be abnormally The correction factor is set to a null value if the correction factor is not determined based on the first formula or the second formula; and operating an engine based on the correction factor. | 10-17-2013 |

20100023513 | USER-SENSITIVE PAGERANK - Techniques are described for generating an authority value of a first one of a plurality of documents. A first component of the authority value is generated with reference to outbound links associated with the first document. The outbound links enable access to a first subset of the plurality of documents. A second component of the authority value is generated with reference to a second subset of the plurality of documents. Each of the second subset of documents represents a potential starting point for a user session. A third component of the authority value is generated representing a likelihood that a user session initiated by any of a population of users will end with the first document. The first, second, and third components of the authority value are combined to generate the authority value. At least one of the first, second, and third components of the authority value is computed with reference to user data relating to at least some of the outbound links and the second subset of documents. | 01-28-2010 |
