摘要： A system for improving the duty cycle output of a vehicle speed sensor circuit is disclosed. The vehicle speed sensor circuit can be configured, for example as a binary counter, to provide a particular number of pulses per distance of vehicle travel. An output of the vehicle speed sensor circuit is generally divided by placing varying values on particular load pins of an associated counter circuit, thereby providing a substantially improved duty cycle output from the vehicle speed sensor circuit, which is independent of an associated sensor duty cycle. The output of the vehicle speed sensor circuit can be divided utilizing a toggle flip-flop circuit integrated with the vehicle speed sensor circuit. The toggle flip-flop can be configured as an edge-triggered toggle flip-flop. The vehicle speed sensor can be utilized to sense rotating members present in a vehicle. The vehicle speed sensor thus provides a digital pulse output for every tooth that passes in front of the vehicle speed sensor.

摘要： A GMI sensor for determining spin rate of a rotating body within an external magnetic field is presented. The sensor comprises an oscillator generating an AC drive signal at an oscillator output terminal. A voltage divider circuit includes a first terminal AC coupled to the oscillator output terminal through a coupling capacitor, and a second terminal electrically connected to a reference ground. The voltage divider circuit further includes a GMI fiber having a GMI junction terminal. The fiber is disposed in fixed relation to the rotating body such that impedance of the fiber is modulated by the external magnetic field to provide a modulated drive signal at the GMI junction terminal. A signal processing circuit is electrically connected to the GMI junction terminal to processes the modulated drive signal and provide an output signal indicative of the spin rate of the rotating body.

摘要： A vehicle speed sensor includes a hollow generally cylindrical sensor housing (102) with an open proximal end (112). Within the interior of the sensor housing (102) is a sensing structure and coupled to the open proximal end (112) of the sensor housing (102) is a connector housing (134).

摘要： A brake includes a rotating element and a magnet wheel mounted on the rotating element so as to rotate with the rotating element about an axis of rotation. The magnet wheel has a first side extending transversely of the axis of rotation and facing the rotating element and a second side extending transversely of the axis of rotation and facing away from the rotating element. A first axial stop interacts with a first stop section located on the first side of the magnet wheel and a second axial stop interacts with a second stop section located on the second side of the magnet wheel for limiting an axial movement of the magnet wheel relative to the rotating element to a first predetermined amount. Along each line extending parallel to the axis of rotation and extending through the first or the second axial stop, the distance between the first stop section and the second stop section is smaller than the distance between the first axial stop and the second axial stop.

摘要： In a vehicle wheel rotation detecting system, a signal input portion of an ECU accurately detects a vehicle wheel speed and a rotating direction of the vehicle wheel speed of the respective wheels. On the basis of the detected results, the respective computers are operated to perform ABS control, TC control and VSC control. When a computing result of the vehicle wheel speed is equal to or greater than a predetermined value, a change in the rotating direction is inhibited. This may prevent an error in the result of detection of the wheel rotating direction owing to an external magnetic filed and the like so as to further optimize the vehicle state control.

摘要： A method for detection of passing magnetic articles which includes an initial step of sensing an ambient magnetic field and generating a voltage, Vsig, proportional to the magnetic field. A threshold voltage is generated as a percentage of the peak-to-peak voltage of Vsig. The method further includes the step of generating a detector output voltage that becomes one binary level when Vsig rises to exceed the threshold voltage and another binary level when Vsig falls to below the threshold voltage. The threshold voltage is updated to track the positive and negative peaks of the Vsig voltage upon each transition of the Vout voltage.

摘要： To provide device capable of enhancing the detection accuracy of a wheel speed detecting device and reducing cost. A wheel speed detecting device for a rear wheel includes a pulsar ring mounted on a rear wheel hub, and a pulse counting sensor mounted on a swing arm. The pulsar ring includes a disc, and pulse detecting holes are formed at a predetermined pitch on a pitch circle drawn at a radially inward circumferential position spaced at a predetermined distance from the outer edge of the disc. The pulse detecting hole is formed in a position on the center side apart from the outer edge of the pulsar ring, leaving the outer edge of the pulsar ring in a circular form. Therefore, it is possible to prevent warpage of the pulsar ring by the outer edge portion if the pulse detecting holes are made by pressing.
