Below according to permanent magnetism magnetic marker NS and the difference of Hall sensor H quantity, there is different mounting means to enter one
Walk explanation：
Mounting means 1：Referring to Fig. 5, the permanent magnetism magnetic marker NS includes permanent magnetism magnetic marker CN and permanent magnetism magnetic identification
Thing CS, the Hall sensor H are and permanent magnetism magnetic marker CN, permanent magnetism magnetic marker CS Special compositions measurement triangle
The Hall sensor Hr of locus, they are fixedly mounted on the same side of Shift lever；The permanent magnetism magnetic marker CN, forever
Magnetic magnetic identification thing CS is respectively and fixedly installed to change on the diverse location of Shift lever and with the variation of Shift lever；The permanent magnetism
Magnetic identification thing CN two opposite magnetic poles corresponding with permanent magnetism magnetic marker CS are towards Hall sensor Hr measurement of inductance
Face.I.e.：When the permanent magnetism magnetic marker of installation has two, two permanent magnetism magnetic markers are towards Hall sensor Hr products manufacturer
It is required that the magnetic pole in measurement of inductance face should be on the contrary, when the magnetic north pole N of the permanent magnetism magnetic marker CN is towards Hall sensor
During the measurement of inductance face that Hr products manufacturer requires（At this moment permanent magnetism magnetic marker CN south magnetic pole S leans against Shift lever A）, then permanent magnetism
The measurement of inductance face that magnetic identification thing CS south magnetic pole S requires towards Hall sensor Hr products manufacturer（At this moment permanent magnetism magnetic mark
The magnetic north pole N for knowing thing CS leans against Shift lever A）；Or when the south magnetic pole S of the permanent magnetism magnetic marker CN is towards Hall sensor
During Hr measurement of inductance face（At this moment permanent magnetism magnetic marker CN magnetic north pole N leans against Shift lever A）, then permanent magnetism magnetic marker CS
Magnetic north pole N towards Hall sensor Hr measurement of inductance face（At this moment permanent magnetism magnetic marker CS south magnetic pole S leans against Shift lever
A）；Permanent magnetism magnetic marker CN, CS pole orientation is parallel to paper in Figure 5.

Shown is the measurement triangle projective planum figure for being approximately parallel to the axial section that partner's bar is in neutral position residing during free state,
Figure apparent direction is that Shift lever i.e. Shift lever axial view is overlooked at station in driver's cabin.Because permanent magnetism magnetic marker is affixed to shift
Changed on bar and with the variation of Shift lever, so being aware of locus where permanent magnetism magnetic marker has also been known that change
Gear positions corresponding to lever.
Fig. 7-1 ~ Fig. 8-2 is the schematic diagram of locus where detecting permanent magnetism magnetic marker：
In principle shown in Fig. 7-1, P is Hall sensor Hr positions in Fig. 5, Q1 be fixed in Fig. 5 on Shift lever and with
The variation of Shift lever and the permanent magnetism magnetic marker CN positions changed, Q2 is to be fixed in Fig. 5 on Shift lever and with shift
The variation of bar and the permanent magnetism magnetic marker CS positions changed；Because Q1 and Q2 are affixed on Shift lever and with shift
The variation of bar and the permanent magnetism magnetic marker changed, therefore the distance between Q1 and Q2 are known, if Hall sensor
Hr perceive the size of the reflection magnetic induction intensity P at caused by Q1 and Q2 respectively as P to Q1 and Q2 distance PQ1 with
PQ2, then the physical location according to residing for the property of triangle can learn Shift lever.We can see that working as from Fig. 7-1
When Shift lever is in neutral position, 3 points of P, Q1, Q2 corresponds to Hall sensor Hr and permanent magnetism magnetic marker CN, permanent magnetism respectively

Sensor Hr and permanent magnetism magnetic marker CN, the permanent magnetism magnetic marker CS position at certain grade（Referring to Fig. 7-2）.
In principle shown in Fig. 8-1, P1 is to be fixed on the Hall that Shift lever does not change nearby and changed with Shift lever in Fig. 6 to pass
Sensor Hr1 positions, P2 are that the Hall sensor Hr2 that Shift lever does not change nearby and changed with Shift lever is fixed in Fig. 6
Position, Q are that any one magnetic pole of N or S for being fixed in Fig. 6 on Shift lever and being changed with the variation of Shift lever leans against shift
Bar A permanent magnetism magnetic marker CNS positions；Due to P1 and P2 be all integrally fixed at Shift lever nearby not with Shift lever change and
The Hall sensor of variation, therefore the distance between P1 and P2 are known, produced if P1 and P2 are perceived Q at P1 and P2
Distance QP1 and QP2 of the size of raw reflection magnetic induction intensity respectively as Q to P1 and P2, then according to the property of triangle
The physical location residing for Shift lever can be learnt.From Fig. 8-1 we can see that when Shift lever is in neutral position, Q,
3 points of P1, P2 corresponds to position, Hall sensor Hr1 and Hall sensors of the permanent magnetism magnetic marker CNS in neutral gear respectively
Hr2；When Shift lever is in certain file location, Q ', 3 points of P1, P2 correspond to positions of the permanent magnetism magnetic marker CNS at certain grade respectively
Put, Hall sensor Hr1 and Hall sensor Hr2（Referring to Fig. 8-2）.
What the permanent magnetism magnetic marker in the present embodiment can be made using magnet or magnet steel or rare earth permanent-magnetic material
Permanent magnet, Hall sensor use linear hall sensor or double magnetic pole Hall sensors.
