摘要： A brake master cylinder-sensor system and method are provided. The system includes a master cylinder, a piston slidably positioned in the master cylinder, a magnet positioned on the piston, and a sensor disposed on the master cylinder. A change of piston linear position causes a linear change in a magnetic field position sensed by the sensor, and a brake control signal proportional to the change of piston linear position is generated. A method of operating a brake master cylinder-sensor system includes applying a brake pedal force, changing a piston linear position within a master cylinder, determining a change in a linear magnetic field position proportional to the change of the piston linear position, and generating a brake control signal based on the change in the linear magnetic field position.

摘要： A variable reluctance rotation sensor comprising a flux member having a ferromagnetic pole piece formed of a cylindrical center portion interposed between a first and second end portion. Each of the end portions have a respective surface which contains elongated teeth, similarly separated by slots as teeth on the periphery of a toothed wheel. The cylindrical center portion is positioned with respect to the toothed wheel such that the toothed surfaces of the first and second end portions are positioned adjacent the periphery of the toothed wheel comprising the teeth and slots, the magnetic flux member and toothed wheel defining an air gap. The sensor further comprises permanent magnets which establish main flux loops traversing the air gap, and leakage flux loops linking an electrical coil wound about the cylindrical center portion. As the toothed wheel is rotated, the magnitude of the main flux loops vary in relation to the varying air gap. The leakage flux loops, in turn, vary in relation to the varying main flux loops, the varying leakage flux loops being linked to the electrical coil and resulting in a sinusoidal output voltage signal proportional to the varying leakage flux loops. Each cycle of the output signal corresponds to a predetermined incremental angular rotation of the toothed wheel.

摘要： An apparatus and method are provided for sensing the position of a point of contact through use of a sensor having a movable element, disposed between a sensing element and a source of magnetic flux, and having an aperture therein for allowing a portion of the magnetic flux from the source of magnetic flux to pass through the aperture and impinge on the sensing element. The aperture may have various shapes to provide a desired linear or non-linear relationship between the position of the movable element and the intensity of the flux that passes through the aperture and impinges on the sensing element for a given position of the movable element.

摘要： A non-contact Hall Effect position sensor integral to a master cylinder for an automotive hydraulic braking system provides reliable brake pedal position information without regard to the geometry and placement of the brake pedal input, decreasing the complexity of integration into each type of automobile. Moreover, reliable performance of brake position sensing is provided by avoiding use of contact sensors that are subject to wear and performance variation.
