The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

Embodiment:

Referring to Fig. 1 and Fig. 2, automobile auto-manual selector gear comprises base 1, Connection Block 2, dust boot 3, gear level 4, commutation seat 8, control circuit board 5 and bottom 6.Commutation seat 8 rotatable being installed on the bottom 6 have the gear positions groove on the bottom 6, its trajectory shape is corresponding with the stick shift position.Control circuit board 5 is positioned at the bottom 6 of the below of commutation seat 8, and corresponding with gear positions groove on the bottom 6.Gear level 4 lower ends are installed with magnet piece 7, see Fig. 3, move in the gear positions groove of the magnet piece 7 on the gear level 4 on bottom 6, see Fig. 5.Pin is rolled in the location that radially is equipped with of gear level 4 bottoms, locatees on the gear level that rolls pin top and is set with retainer spring; Commutation seat 8 be the polygonal frame shape, and roll on the framework that pin is positioned at commutation seat 8 bottoms the location of gear level 4, and retainer spring rolls pin and commutates between the 8 framework inside top in the location.

Drive commutates when gear level 4 rotates, and seat 8 rotates or at commutation its orbiting motion of upper edge, place the magnet piece 7 of gear level 4 bottoms along with moving to diverse location at this moment.The Hall element of arranging on the control circuit board 5 is corresponding one by one with different gear positions, promptly has unique respective notch position signal to export to transmission control unit when magnet piece 7 moves to a certain position, to realize shift control.

Present embodiment has six gear positions, and each gear positions all has a logical signal and its unique corresponding.The present embodiment logical signal is formed by four tunnel signal combination, and the logic level of each gear positions is as shown in the table:

	Signal 1	Signal 2	Signal 3	Signal 4
					Position 1	0	?1	?1	?0
Position 2	0	?0	?1	?1
					Position 3	0	?1	?0	?1
Position 4	1	?0	?1	?0
					Position 5	1	?0	?0	?1
Position 6	1	?1	?0	?0

Logical one is represented voltage 3.20 ± 3.20 * 5% (V)

Logical zero is represented voltage 1.75 ± 1.75 * 5% (V)

Referring to Fig. 4, the function of each position is as follows:

1. the position is automatic and manual switchover position, with " A/M " expression;

2. the position is manually to add P PARK Position P, with "+" expression;

3. the position is the cruising position;

4. the position is manual downshift position, with "-" expression;

5. the position is a Neutral Position, with " N " expression;

6. the position is a reverse gear position, with " R " expression;

The present embodiment shift process is an example to reverse gear, chaufeur is described as follows: when will be hung reverse gear, handle gear level 4 and hang " R " shelves, being positioned at the magnet piece 7 of gear level 4 bottoms this moment 6. locates with the position that gear level 4 moves to bottom 6, then 6. the Hall element on the control circuit board 5 senses the position, output signal 1100 after decision circuit is handled.Transmission control unit is controlled shift-selecting and changing actuating mechanism immediately and is hung into reverse gear after receiving 1100 logical signals, thereby realizes whole shift control process.
