摘要： The invention provides a software method to correct for non-fuel injection induced errors in measured engine speed. This invention provides a means to calculate a least squares regression of the measured engine speed data when the engine is motoring without combustion or load. The motoring test is to avoid the effect of unbalanced cylinder power, thus detecting only the static errors in engine speed measurements. Recognizing that the average cylinder speed should form a straight line within an engine cycle, the lease squares regression of the measured speed data therefore represents the theoretical performance of the engine. A residual between this theoretical performance and the actual measured engine speed can therefore be determined. A table of mean residuals which are averages of individual residuals measured in consecutive engine cycles is constructed for each engine at a reference engine speed. The mean residuals are convertible to other operating speed ranges of the engine and can be subtracted from the engine speed measurements to remove the static errors. This mean residual table is stored as a look-up table in the memory associated with the engine control module (ECM) microprocessor and can be implemented within the software code being executed by the ECM microprocessor.
摘要翻译：本发明提供了一种在测量的发动机转速下校正非燃料喷射引起的误差的软件方法。本发明提供了当发动机在没有燃烧或负载的情况下进行运动时，计算所测量的发动机转速数据的最小二乘回归的方法。电动试验是为了避免不平衡气缸功率的影响，从而仅检测发动机转速测量中的静态误差。认识到平均气缸速度应在发动机循环内形成直线，因此测量速度数据的租赁平方回归表示发动机的理论性能。因此可以确定该理论性能与实际发动机转速之间的残差。以参考发动机速度为每台发动机构造在连续发动机循环中测量的各个残差的平均值的平均残差表。平均残差可转换为发动机的其他工作速度范围，并可从发动机转速测量中减去以消除静态误差。该平均剩余表作为查找表存储在与发动机控制模块（ECM）微处理器相关联的存储器中，并且可以在由ECM微处理器执行的软件代码内实现。

摘要： A serial bus control system for an automatic sewing station for attaching a series of work pieces includes a serial bus cable connected to a power supply and a system controller. A program module is plugged into the serial bus cable and is programmed with an operations program or set of command instructions that are accessed and run by the system controller for controlling the automatic sewing station. A series of input modules are removably connected to the serial bus cable and receive inputs from various detectors monitoring the position and movement of the work pieces along a sewing path through the automatic sewing station. The input modules transmit this input information to the system controller via the serial bus cable in response to which the system controller sends command signals to a series of output modules that are connected to the operative elements of the sewing station, such as a sewing machine and upstream and downstream drive assemblies, to control the operation of the sewing machine and such other operative elements of the sewing station.

摘要： Method and apparatus for controlling the calibration of an instrument. In a representative embodiment, a method includes determining instrument calibration status, wherein the determination is made automatically by the instrument examining calibration history data stored by the instrument. When instrument calibration is past due, a user is notified that the calibration is past due, wherein the notification is initiated automatically by the instrument. The user can decide to make the measurement with the out-of-calibration instrument. Otherwise, the instrument is removed from measurement service, the instrument is calibrated, the calibration history stored by the instrument is updated to reflect a new time that a new calibration is due, and the instrument is returned to measurement service. Also described are techniques for calibrating only those signal paths, subsystems, and ranges are actually being used or may potentially be used. In addition, if the user does decide to make a measurement while the instrument is out of calibration, he may be informed of the measurement uncertainty in making such a measurement.

摘要： A fault detection system for determining whether a fault exists with a rotating element of a vehicle. The system includes a transducer, a diagnosis sampler, a sensor, and a controller. The transducer may be a microphone located in the vehicle for converting sounds to an electrical signal. The electrical signal includes a noise component generated from the rotating element. The diagnosis sampler is connected to the transducer and provides a sample of the electrical signal from the transducer to the controller. The sensor obtains data relating to the rotating element. The controller has functional aspects such as a synchronous resample, a spectrum analysis, and a fault detect. The synchronous resample has the capability of synchronizing the sample of the electrical signal with the data from the sensor to form a synchronized envelope. The spectrum analysis has the capability of forming a spectra from the synchronized envelope of the electrical signal, where the spectra is associated with the noise component generated from the rotating element. The fault detect has the capability of determining (from the formed spectra) whether the fault exists with the rotating element. There is also a method of detecting a fault associated with a rotating element in a vehicle using the above-described system.

摘要： A malfunction determining apparatus of an engine system that has an improved malfunction determining accuracy. The apparatus includes a processing unit. The processing unit performs a test for the engine system every time a predetermined condition is satisfied and determines whether there is a malfunction in the engine system based on the test result. The number of times when a malfunction is detected is represented by malfunction counter value. The processing unit evaluates the reliability of malfunction counter value based on a normality counter value. When the malfunction counter value is reliable and reaches a predetermined value, the processing unit determines that there is a malfunction in the engine system.

摘要： A diagnostic system in an engine management system is provided for generating a diagnostic trouble code (DTC) to indicate the operational status of a component or a sub-system. The diagnostic system includes a diagnostic function module (DF module) for each DTC or a group of related DTCs associated with a component or sub-system. The DF module includes means for executing an evaluation routine to evaluate a component/sub-system to which the DTC of the specific DF module relates, and a dynamic scheduler for determining which DF module may be allowed to execute an evaluation routine at a particular time. Each DF module includes means for producing a ranking value dependent on the operating status of the component or sub-system being evaluated, a ranking value being generated each time an evaluation routine is performed; means for processing and storing statistical results of the ranking values obtained over a number of evaluation routines; means for evaluating the statistical results to produce evaluated data in the form of either an evaluated no-fault signal or an evaluated fault signal, and means for establishing the priority of the associated evaluation routine, and means for transmitting the evaluated signals to the dynamic scheduler.
