    • A locking strut including a housing with a piston rod extending therethrough. A baffle mounts on the piston rod to divide the housing into two chambers. An orifice through the baffle allows fluid to pass between the chambers to damp reciprocating movement. An electromagnetic driver within the housing is selectively energized to move a ferromagnetic plate between an open position, wherein fluid flows freely between the chambers, and a closed position, wherein the ferromagnetic plate blocks the orifice to prevent fluid flow between the chambers and lock the locking strut in position. A plurality of orifices may be spaced about the baffle, with the number and size of the orifices determining the damping capability of the locking strut. A plurality of drivers may be disposed within the housing to overcome fluid forces during movement of the locking strut between an extended and a retracted position.
    • 锁定支柱,包括具有延伸穿过其中的活塞杆的壳体。 挡板安装在活塞杆上,将壳体分成两个腔室。 通过挡板的孔允许流体在室之间通过以阻止往复运动。 壳体内的电磁驱动器被选择性地通电以将铁磁板移动在打开位置之间,其中流体在腔室之间自由流动并且处于关闭位置,其中铁磁板阻挡孔口以防止流体在腔室之间流动并锁定锁定 支柱就位。 多个孔可以围绕挡板间隔开,孔的数量和尺寸确定锁定支柱的阻尼能力。 多个驱动器可以设置在壳体内以克服在延伸和缩回位置之间的锁定支柱移动期间的流体力。

    • An engine controller system employs angular position sensors which are operable to very accurately determine the position of rotating engine members. Information about the angular position of the engine members is used to alter operation of the engine for improved efficiency and/or reduced emissions from the engine. The angular position of the crankshaft and camshafts can be determined by affixing a dipole magnet to each of them such that the magnet field of the magnet rotates with the rotating member and then placing a angular position sensor adjacent each rotating member to detect the rotation of each magnetic field. In another embodiment, the angular position of each end of at least one of the rotating members is determined to allow the processor to determine the torsional deflection of the member and the engine controller system is responsive to that determined deflection to further alter operation of the engine.
    • 发动机控制器系统采用角位置传感器,其可操作以非常精确地确定旋转的发动机构件的位置。 关于发动机构件的角位置的信息用于改变发动机的操作,以提高效率和/或减少发动机的排放。 曲柄轴和凸轮轴的角度位置可以通过将偶极子磁体固定到它们中来确定,使得磁体的磁场与旋转构件一起旋转,然后在每个旋转构件附近设置角位置传感器以检测每个旋转构件的旋转 磁场。 在另一个实施例中,至少一个旋转构件的每个端部的角位置被确定为允许处理器确定构件的扭转偏转,并且发动机控制器系统响应该确定的偏转以进一步改变发动机的操作 。

    • A control system and method for controlling a vehicle system, such as an engine, is taught. The controller uses the angular position of a rotating component, and in particular the angular phase of the rotating component to another rotating component, as an input. The input is determined with high resolution, yet is determined in a computationally efficient manner to reduce the amount of computation which must be performed by the controller. By producing a high resolution result in a computationally efficient manner, the result can be available to the controller almost immediately after the measurement is taken and the cost of controller can be less than it otherwise would be. In some embodiments, the system and method can also accurately determine the static angular position of one or more rotating members. The system and method are believed to be particularly suitable for determine the angular phasor between one or more camshafts and the crankshaft of an engine.
    • 教导了用于控制诸如发动机的车辆系统的控制系统和方法。 控制器使用旋转部件的角度位置,特别是旋转部件的角度相位作为输入。 以高分辨率确定输入,但是以计算有效的方式确定,以减少必须由控制器执行的计算量。 通过以计算有效的方式产生高分辨率的结果,结果可以在测量之后几乎立即可用于控制器,并且控制器的成本可以小于另外的控制器的成本。 在一些实施例中,系统和方法还可以精确地确定一个或多个旋转构件的静态角位置。 认为该系统和方法特别适用于确定一个或多个凸轮轴与发动机曲轴之间的角度相位。
