摘要： Disclosed herein are methods of generating an active crank series of signals that is derived from at least two series of signals, wherein one or both of the series of signals have been modulated to produce two series of signals that resemble each other. Also disclosed herein is a crankshaft positioning system for determining the rotational position of a crankshaft of an engine that utilizes at least two crank angle sensors 10 and 12. The signal information from the two crank angle sensors 10 and 12 is processed by a signal processor 150 such that the series of signals 220 from the second crank angle sensor 12 emulates the series of signals 210 from the first crank angle processor 10. The signal processor generates an active crank series of signals 230 based on the two series of signals 210, 220. The active crank series of signals 230 is sent to an engine control processor 120 which directs the injection and/or ignition of fuel into cylinders of an engine. According to the system exemplified herein, the active crank series of signals 230 sent to the engine control processor 120 is not disrupted despite failure of one of the crank angle sensors. These and other embodiments are disclosed.
摘要翻译：这里公开的是产生从至少两个系列信号导出的主动曲柄系列信号的方法，其中一系列信号已经被调制以产生彼此类似的两系列信号。本文还公开了一种用于确定使用至少两个曲柄角传感器10和12的发动机的曲轴的旋转位置的曲轴定位系统。来自两个曲柄角传感器10和12的信号信息由信号处理器150处理，使得来自第二曲轴转角传感器12的一系列信号220模拟来自第一曲柄角处理器10的一系列信号210。信号处理器基于两个系列信号210,220产生主动曲柄系列信号230。主动曲柄系列信号230被发送到引擎控制处理器120，发动机控制处理器120将燃料的喷射和/或点火引导到发动机的气缸中。根据这里示出的系统，尽管发动机控制处理器120中的一个曲柄角传感器的故障也不会中断发送到发动机控制处理器120的主动曲柄系列信号230。公开了这些和其他实施例。

摘要： The invention relates to a system and method for detecting a closing of a solenoid. The system includes a capacitive charge circuit electrically coupled to the solenoid. The capacitive charge circuit conditions the current flow through the solenoid to increase the current in response to the closing of the solenoid. The invention also relates to a system and method that includes detecting a current through the solenoid and determining a current slope characteristic. The current slope characteristic is a function of the current and time. The method also includes conditioning an electrical characteristic of the solenoid such that the conditioning is in response to a current slope parameter. The current slope parameter defines a change in the current after removal of an electrical charge to the solenoid.
