    摘要： An electromagnetic valve for use in controlling fluid flow between first and second passageways in a hydraulic valve block includes a valve body. The valve body defines a central axis, has a central opening therethrough, and has a lower end adapted to be inserted into a bore of the valve block. A hollow valve dome is attached to an upper end of the valve body. An armature is axially moveable within the valve dome. A spring biases the armature in one axial direction. A closing element is coupled to a lower end of the armature. An electromagnetic coil coaxially surrounds the armature and is operable to effect axial movement of the armature in an axial direction opposite the one axial direction. A valve seat member is carried by a lower end of the valve body and has an orifice providing fluid flow between the first and second valve block passageways. The valve seat member defines a valve seat that surrounds the orifice and cooperates with the closing element for selectively closing the orifice. The valve seat member is formed as a deep drawn part and includes a tubular portion having one end defining a valve seat, and an opposite end connected to the valve body.

    摘要： A switch mechanism 10, 110, 210 includes a support 24 and a plurality of switches 50 connected to the support 24. An encoder 26 connected to the support 24 has a shaft 28 rotatable about an axis 18 of the shaft relative to the support. The encoder 26 sends a signal in response to a sensed rotational position of the shaft 28 about the axis 18 relative to the support 24. An actuator 12 is rotatable with the shaft 28 about the axis 18 of the shaft relative to the support 24 and tiltable relative to the axis of the shaft to actuate any of the plurality of switches 50 when the shaft is in any rotational position relative to the support. A connector assembly 30, 130, 230 interconnects the actuator 12 and the shaft 28. The connector assembly 30, 130, 230 transmits rotational movement of the actuator 12 to the shaft 28 and permits tilting movement of the actuator relative to the axis 18. Each of the switches 50 has a central axis 52 and an upper surface 54 that moves to actuate the switch. A lever 60 is pivotal about a pivot axis 78. The lever 60 has a lower surface 64 engaging the upper surface 54 of the switch 50 at a first location 66 on the central axis 52. The actuator 12 engages an upper surface 70 of the lever 60 at a second location 74 to pivot the lever toward the upper surface 54 of the switch 50 to actuate the switch. The pivot axis 78 is spaced from the first location 66 a first vertical distance Dl extending parallel to the central axis 52 of the switch 50. The second location 74 is spaced from the first location 66 a second vertical distance D2 in a direction extending parallel to the central axis 52. The first distance Dl is smaller than the second distance D2.

    摘要： A method of boundary auto-calibration for proportional poppet valve pressure control comprises implementing an estimator to estimate a boundary deviation of the valve. A pressure command signal is detected and its derivative over time is obtained. Then, determining which closing boundary should be updated is decided based on the sign of the pressure command derivative. A pressure error is obtained by subtracting an actual wheel brake pressure from its pressure command. Then a modified pressure error is calculated and implemented in the estimation. Finally, a boundary table is updated using the resultant boundary deviation estimate. An alternate embodiment implementing a fast boundary auto-calibration scheme includes a quasi-closed-loop pressure control system. The auto-calibration test is preferably set up so that the test only needs one cycle of pressure upward sweep and pressure downward sweep in order to cover the entire operating range of pressures for the valves.

    摘要： A sensor for sensing the angular position of a rotor includes a code disk rotatable with the rotor. A first light guide is rotatabie with the rotor. The light guide directs tight from a light source through the code disk to a detector. A second light guide has first and second arms, directing light from a light source to the detector. A light modulator modulates Ae light directed from one of the first and second arms to the detector. A method for determining the angular position of the rotor includes providing the code disk with a plurality of individual designation areas located near the outer peripheral edge of the disk, Each designation area has a plurality of digital bits. The detector detects the digital bits from a selected portion of the code disk. The selected portion is functionally reiated to the angular position of the rotor. A bit center is determined for each bit of the selected portion. The bit is determined to be a 1 or a 0 b\ determining a value related to the bit based on the determined bit center and comparing the determined value against a threshold. The determined 1's and 0's are monitored to idemif) a code word. The angular position of the rotor is identified based upon the identified code word.
