After utilizing above formula to calculate in the space arbitrarily the magnetic field intensity H of a bit, can obtain the size of magnetic induction density according to the relation

of magnetic induction density B and magnetic field intensity H.Obtain after the magnetic induction density, the sensor-triggered situation that should put just is very easy to judge.

In addition; Adopting equivalent magnetic charge method to set up in the mathematical model step; Need to consider the influence of many factors to magnetic induction density, for example: comprise the radius and the height of cylindrical magnet, the length and width of square magnet are high; Magnet lower surface center is with respect to the coordinate of circuit board, and the angle of magnet rotation and rotary middle point are apart from shape and the location parameter at interior magnet such as the height of circuit board; The relative permeability of the surface charge density of magnet and magnet material therefor; The Hall switch sensor of different model is provided with corresponding operating point etc.

Fig. 2 is automotive electronics gear ultimate principle figure.As shown in Figure 2; The ultimate principle of electronics gear commonly used is to place the long-pending very little permanent magnet 2 of a block in the gear shift operating rod bottom; When the driver stirs gear shift operating rod; Permanent magnet 2 moves along with the motion of gear shift operating rod 1, and Hall switch sensor 6 induced fields on the circuit board change, and can judge driver's gear selection according to the trigger pip combination of a plurality of sensors.

Fig. 3 is that auxiliary simulation software uses process flow diagram.As shown in the figure, each parameter of considering when setting up model is corresponding, and the emulation personnel can carry out the shape and the location parameter setting of magnet; The radius and the height that comprise cylindrical magnet; The length and width of square magnet are high, and magnet lower surface center is with respect to the coordinate of circuit board, and the angle of magnet rotation and rotary middle point are apart from the parameters such as height of circuit board; And in being drawn in the space in the three-dimensional drawing district visually the magnet of difformity and position, be the convenient color that also can set different magnets of distinguishing.Then according to the surface charge density of magnet and the parameters such as relative permeability of magnet material therefor, so that calculate the magnetic field size of magnet diverse location in the space of different materials.Sensor according to different model is provided with the corresponding action point afterwards, and for same magnet, if the operating point of sensor increases, then the relative trigger zone can dwindle, otherwise the zone enlarges.At last also can be according to the different parameters of magnet and sensor; The relative trigger zone of in the three-dimensional drawing district, drawing visually; For the designer can fast be distributed according to the analysis result sensor designs intuitively; Also can toggle area be presented in the two-dimensional coordinate system, and the demonstration color consistent with magnet is so that distinguish.

The emulation personnel can guarantee under each gear, to have only a sensor-triggered as long as place a Hall switch sensor 6 in different toggle area when sensor designs distributes; The error condition that can not exist two sensors to trigger simultaneously again; And the accuracy and the security that have improved gear shift operation better meet the designing requirement of electronics gear.

Electronics gear of the present invention has 6 gear definition, and is as shown in Figure 4, and the current present position of gear shift operating rod is a D retaining (forward gear); D retaining front side is a M/A retaining (retaining that cruises cruises/cancel); The D retaining left and right sides is respectively "+" retaining (cruise and quicken retaining) and "-" retaining (retaining that slows down cruises); The left and right sides at D retaining rear is respectively N retaining (neutral and Parking retaining) and R retaining (reverse gear shift).Gear shift operating rod of the present invention can be stablized the arbitrary gear that rests in D retaining, N retaining and the R retaining respectively; All the other gears are the transient state gear; After the driver pushed gear respectively said M/A retaining, "+" retaining, "-" retaining, gear shift operating rod all can return the D gear automatically and put.

Fig. 5 is that a kind of 6 blocks of the present invention are from one automotive electronics gear structural representation.As shown in Figure 5, a kind of 6 blocks of the present invention mainly comprise from one automotive electronics gear: a solid space 7, circuit board 3 that main panel 4, gear shift operating rod 1, permanent magnet 2, base 5, said main panel and said base surround.

Fig. 6 is the synoptic diagram of circuit board described in Fig. 3.As shown in Figure 6,6 Hall switch sensors 6 that on circuit board, distributed are corresponding respectively with 6 gears, and these 6 sensors are confirmed after the distribution on the circuit board is through said software emulation.When the driver carries out gear shift operation; The permanent magnet movement therewith of gear shift operating rod bottom, the magnetic field in space produces respective change, makes the Hall switch sensor action on the circuit board; The single-chip microcomputer pin that links to each other just has voltage jump to cause the one-chip machine port interruption; Utilize single-chip microcomputer input capture function, the triggering status signal that can collect 6 sensors fast is input to single-chip microcomputer simultaneously and handles, and single-chip microcomputer is through 4 logical values of 4 reverser output; Entire car controller comes the gear of identification of driver selection by the corresponding relation of 4 logical values and gear, and sends shifting commands.

More than show and described ultimate principle of the present invention, principal character and major advantage.The technician of the industry should understand, and the present invention is not restricted to the described embodiments, and the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by claims and equivalent thereof.
