Mark system, using magnetic field strength as Z axis, move distance is Y-axis, rotation angle be X-axis, according to magnetic field strength differentiation keep off, reverse gear and
The corresponding relationship of neutral gear；Third step, analog simulation Distribution of Magnetic Field: according to the track of magnet movement, magnetic field when skimulated motion is strong
Degree forms the curve graph with peaks and troughs, corresponds to neutral gear at wave crest, correspond to reverse gear at trough, between Wave crest and wave trough
Plane be to keep off, further according to move distance, determine each gear in gear；4th step, according to analogue simulation Distribution of Magnetic Field figure
Determine magnet shape, magnet includes two, two magnet arc distributions；5th step carries out simulated experiment to magnet and obtains magnetic field
Distribution map, then optimize.Gear is distinguished using magnetic field strength, signal is strong, is able to achieve quick start, and gear is distinguished clear
It is clear.Neutral gear and to reverse gear one be one, wave crest be trough, is able to achieve rapid starting/stopping, compared to original according to the determination of magnetic line of force direction
Gear, it is easier to determine, gear is more clear.Magnet is fixed in shaft, and with shaft synchronous rotary, chip is fixed on shell,
Fixed, when magnet rotates, the magnetic field strength that chip is experienced is changing, and according to the angle and distance that magnet rotates, carrys out mould
Quasi- Distribution of Magnetic Field figure meets then further according to the shape of Distribution of Magnetic Field G- Design magnet and distinguishes gear using magnetic field strength
Purpose.The distribution of two magnet arcs is exactly that the outer surface of two magnet is located on same camber line, and the magnet holder for installing magnet is
Arc, in this way, facilitating installation of two magnet in magnet holder.
Preferably, the 1 of shift sensor, 3,5 gears and reverse gear positioned at the same side, neutral gear is located at centre, 2 and 4 gears in
The other side of neutral gear arranges that emulation Distribution of Magnetic Field figure is corresponding with gear, in X-direction, neutral gear according to the gear of shift sensor
Most strong corresponding to magnetic field strength at wave crest, the two sides of wave crest are plane, and magnetic field strength is identical, and in the left side of wave crest, Y direction goes out
Existing trough, the corresponding position of reversing gear of trough.
Preferably, one of length is greater than another magnet in two magnet, one end of two magnet is concordant,
One end of the small magnet of length increases collection magnetic sheet according to magnetic field strength, improves the magnetic field strength reversed gear, makes trough shape more clear
It is clear.Length length is the first magnet, and the cross section of the first magnet is rectangle, and length is short for the second magnet, the cross of the second magnet
Section be it is trapezoidal, the cross section for collecting magnetic sheet is identical as the second magnet.
Therefore, a kind of Magnet design method of shift sensor of the invention has following advantages: using magnetic field strength come
It determines and is keeping off, reversing gear and neutral gear, fast response time, be able to achieve crash change of speed starting, and magnetic field strength is more intuitive, facilitates prison
Survey, precision is high, is reversed gear magnetic field strength using collection magnetic sheet enhancing, allow reverse gear it is apparent.
