摘要： A system and method for reducing or eliminating built-in tests and diagnostic trouble codes that are set as a result of improper parameter values. The method includes collecting field failure data that identifies diagnostic trouble codes and parameters of the system that are used to set diagnostic trouble codes. The method transforms the collected data into a format more appropriate for human analysis and pre-processes the transferred data to identify and remove information that could bias the human analysis. The method includes plotting linear and nonlinear combinations of operation parameters, performing data mining and analysis for detecting inappropriate settings of fault codes in the pre-processed data and providing the mined data to a subject matter expert for review to determine whether a diagnostic trouble code has been issued because of improper parameters.

摘要： A vehicle speed detection system includes a first module that checks a plurality of vehicle operating conditions and a second module that checks a plurality of vehicle set-up conditions. A third module generates a control signal based on output signals provided by the first and second modules. The control signal indicates that a vehicle speed is to be determined based on an anti-lock braking system (ABS) sensor signal if each of the plurality of vehicle operating conditions and each of the plurality of vehicle set-up conditions is met.

摘要： A method for determining a position of a rotating shaft and, more particularly, for determining a sync position of an engine crankshaft or engine camshaft. The method includes sequentially measuring consecutive time periods generated in response to rotation of the shaft, and comparing each measured time period to a value calculated from a predetermined function based on more than one measured time period to determine the sync position. Preferably, the comparing step includes comparing a penultimate measured time period to a product of a sync factor and the sum of an ultimate measured time period, the penultimate measured time period, and an antepenultimate measured time period. After determining the sync position, the method includes sequentially measuring a predetermined number of consecutive time periods generated in response to further or continued rotation of the shaft, and comparing a penultimate measured time period to a value calculated from the predetermined function to verify the sync position.

摘要： A method for adjusting the timing of an internal combustion engine having a crankshaft and a camshaft to manage the thermal load on the engine. The method includes the step of altering the timing of the camshaft with respect to the timing of the crankshaft to reduce thermal load on the engine. Preferably, the step of altering the timing of the camshaft is accomplished with a variable camshaft phaser.

摘要： An engine controller diagnostic system includes a cylinder identification (ID) comparison module and a synchronization diagnostic module. The cylinder ID comparison module compares a first cylinder ID associated with a first controller with a second cylinder ID associated with a second controller. The synchronization diagnostic module determines a synchronization status of the first controller based on a comparison between the first cylinder ID and the second cylinder ID.
