摘要:
Provided by the present invention is a device for detecting vehicle operation parameters. A casing deforms due to a force, which changes the magnetic permeability of a magnetic material on the casing. A coil induces the generation of corresponding induced electromotive force, and a corresponding torque value may be obtained by analysis. The magnetic flux density distribution on the surface of a magnetic ring in a region of the same polarity has the characteristic of a part being a strictly increasing or decreasing function, so that a first or second Hall sensor outputs a corresponding analog voltage value which may correspond to the position angle value of a central axis. The magnetic ring may be driven by the rotation of the central axis, so that the magnetic flux density distribution in space changes, and the voltage outputted by the first or second Hall sensors changes correspondingly. The position angle value or the rotation angle value of the central axis may be obtained by analysis, and the rotation speed value of the central axis may be obtained by taking the change value of the central axis with time. With the present invention, accurate vehicle operation parameters may be fed back, thereby improving the riding experience.
