It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Fig. 2 shows a schematic structural diagram of a chest gear shifter according to the present invention, which includes: a gear shift lever 1, a plurality of first detecting elements 2, and a controller (not shown in the figure), wherein the gear shift lever 1 rotates around a rotating shaft 11 in a first plane, the plurality of first detecting elements 2 are fixed on a second plane parallel to the first plane and are arranged along a moving path of a tail end 12 of the gear shift lever 1, and a second detecting element 3 is arranged at the tail end of the gear shift lever 1;

the controller switches the gear shifting position of the automobile according to the relative position relation of the first detection element 2 and the second detection element 3.

Specifically, the shift lever 1 rotates about the rotation shaft 11, and the rotation surface of the shift lever 1 is a first plane. The rotation axis 11 is located in the middle of the first detection element 2.

The plurality of first detecting elements 2 are fixed on a second plane parallel to the first plane and arranged along the movement path of the end 12 of the gear shift lever 1, so that the end 12 of the gear shift lever 1 will pass different first detecting elements 2 during the rotation.

The second detecting element 3 is arranged at the position of the tail end 12 of the gear shifting rod 1, and the gear shifting rod 1 rotates to drive the second detecting element 2 to pass through different first detecting elements 3.

The relative positional relationship can be output by the first detecting element 2 or the second detecting element 3 to the controller, and the controller determines the rotation angle of the shift lever 1 according to the relative positional relationship of the first detecting element 2 and the second detecting element 3, so as to switch the shift position of the automobile.

As shown in fig. 2, a hand-gear shifter according to an embodiment of the present invention includes: the automatic gearshift device comprises a gear shift lever 1, a plurality of first detection elements 2, a controller and an electronic key 4 arranged on the gear shift lever 1, wherein the gear shift lever 1 rotates on a first plane around a rotating shaft 11, the plurality of first detection elements 2 are fixed on a second plane parallel to the first plane and are arranged along an arc motion path of a tail end 12 of the gear shift lever 1, and a second detection element 3 is arranged at the tail end of the gear shift lever 1;

the first detection element 2 is a magnet, the second detection element 3 is a hall sensor, and the gear shifting position of the automobile is switched according to the polarity signal detected by the second detection element 3 and the key signal of the electronic key 4;

the hand-gear shifter comprises a plurality of first detection elements 2, the polarities of two adjacent first detection elements 2 are opposite, the first detection elements 2 are arranged in a close-proximity mode to form an arc-shaped base, and the tail end of the gear shifting rod 1 moves along the circumferential direction of the arc-shaped base.

Specifically, since the shift lever 1 rotates about the rotation shaft 11, the movement path of the tip end 12 of the shift lever 1 is preferably an arc-shaped movement path. While the first detecting member 2 is arranged along the movement path of the end 12 of the gear shift lever 1, i.e. the first detecting member 2 is arranged along an arc-shaped movement path.

As shown in fig. 2, the first detecting element 2 is a magnet, and may include three first detecting elements 2. The plurality of first detecting elements 2 are arranged closely to form an arc-shaped base, and the polarities of two adjacent first detecting elements 2 are opposite. The opposite polarity means that the polarities of the faces of the adjacent first detecting elements 2 facing the second detecting element 3 are opposite. For example, from left to right, the polarity of the side of the first detecting element 2 facing the second detecting element 3 may be north (N), south (S), and north (N) in this order. The second detection element 3 is a hall sensor, and determines the position of the second detection element 3 based on the detected polarity. As shown in fig. 7, the determination may be made according to the voltage difference output by the hall sensor, and if the voltage difference is a positive level, it indicates that the N pole is detected, and if the voltage difference is a negative level, it indicates that the S pole is detected. When no polarity is detected, the hall sensor output is 0. Therefore, the relative position relationship between the first detecting element 2 and the second detecting element 3 can be represented by the polarity signal detected by the second detecting element 3, so that the shifting position of the vehicle is switched according to the polarity signal detected by the second detecting element 3.

For example, take fig. 2 as an example. When the second detecting element 3 detects the S signal, it is determined that the second detecting element 3 is located in the middle, and when the second detecting element 3 detects the N signal, it is determined that the second detecting element is located on both sides.

Due to the change of the signal received by the second detection element 3, a different polarity of the first detection element 3 is detected as a result of the second detection element 3 following the rotation of the gear shift lever 1. Thus, a change of a different gear can be triggered on the basis of the signal received by the second detection element 3.

In order to determine whether the shift lever 1 is rotated to the left or right in fig. 2, in one embodiment, two second detecting elements 3 are included, and the two second detecting elements 3 are respectively located on both sides of the shift lever 1 in the axial direction;

the switching of the shift range of the automobile according to the relative position relationship between the first detection element 2 and the second detection element 3 specifically includes: the shifting gears of the automobile are switched according to the combination of the polarity signals detected by the two second detection elements 3.

As shown in fig. 2, the two second detecting elements 3 are respectively located on both sides of the shift lever 1 in the axial direction, wherein the hall sensor H1 is located on the left side of the shift lever 1 in the axial direction, and the hall sensor H2 is located on the right side.

It is determined that the shift lever 1 is located in the middle when both the hall sensors H1, H2 detect the S signal, and it is determined that the shift lever 1 is rotated leftward when the hall sensor H1 detects the N signal and the hall sensor H2 detects the S signal. When the hall sensor H1 detects the S signal and the hall sensor H2 detects the N signal, it is determined that the shift lever 1 is rotated rightward.

Accordingly, the relative positional relationship between the first detecting element 2 and the second detecting element 3 can be expressed by a combination of the polarity signals detected by the two second detecting elements 3. The shifting position of the vehicle is switched according to the combination of the polarity signals detected by the two second detection elements 3.

Finally, the electronic key 4 can be added, and the key signal of the electronic key 4 can be detected by adopting various existing modes. The key signal of the electronic key 4 is input to the controller. As shown in fig. 8, when a high level voltage is output, it indicates that the user presses the electronic key 4, i.e. the P signal is detected. When a low level voltage is output, it indicates that the user does not press the electronic key 4, i.e. a non-P signal is detected.

The controller switches the gear shifting position of the automobile according to the relative position relationship between the first detection element 2 and the second detection element 3 and the key signal of the electronic key 4.

Due to the relative positional relationship of the first detecting element 2 and the second detecting element 3, it is possible to represent by a combination of polarity signals detected by the two second detecting elements 3. Therefore, the shifting of the gear of the vehicle can be controlled according to the combination of the polarity signals detected by the two second detection elements 3 and the key signal of the electronic key 4.

TABLE 1 polarity signal and shift level table corresponding to key signal

Gear shifting position	H1 detection signal	H2 detection signal	P signal
				P	S	S	1
H	S	S	0
				R	S	N	0
D	N	S	0
				N	S	N		1

As shown in table 1, the H1 detection signal is the detection signal of the hall sensor H1, and the H2 detection signal is the detection signal of the hall sensor H2. The P signal is a key signal of the electronic key 4, where 1 indicates that the electronic key 4 is pressed, and 0 indicates that the electronic key 4 is not pressed.

In this embodiment, two hall sensors may be optimally used, and the output of different gear signals is realized through the arrangement and combination of the sensing signals of the two hall sensors and the combination of the electric signals of the P-gear button.

For example: r: SN1, H gear: SS0, R gear: SN0, D gear: NS0, N gear: SN 1.

The controller chip can process the hall signal and the electrical signal simultaneously. The single Hall signal can be used for identifying a single gear, and the single electric signal can also be used for identifying a single gear. The combination of the hall signal and the electrical signal can also realize the identification of a single gear. By combined signal processing, the number of hall elements or electrical elements can be reduced.

During the driving of the vehicle, the gear shifting is prohibited after the speed is more than 8km/h, even if the gear shifter sends a signal. The shift is only effected when the vehicle is stopped in place and when the brake pedal is depressed. The instrument has a prompt corresponding to the gear.

The gear triggering condition for switching the gear R is that a user only dials the shift lever to the gear R to trigger the gear. The P range should not be pressed at the same time. The P-gear is not pressed, and the electric signal representing the P-gear is 0 (low potential). And the triggering condition of the N gear is that a Hall signal of the R gear and an electric signal of the P gear are simultaneously triggered, namely, the gear lever is shifted to the R gear position, and the P gear is pressed down (high potential). N-gear corresponds to 2 positions being triggered simultaneously. Belonging to a slightly more complex operation. However, since the frequency of use of the N range is low in terms of the customer's vehicle usage, the N range is specifically designed as such.

The gear shifter has the advantages of fewer internal parts and gears, better space and weight, simpler structure and simpler user operation. Compared with the traditional 5-position gear shifter at present, the design of parts is greatly simplified.

As shown in fig. 3, a hand-gear shifter according to an embodiment of the present invention includes: the gear shifting device comprises a gear shifting rod 1, a plurality of first detection elements 2 and a controller, wherein the gear shifting rod 1 rotates around a rotating shaft 11 in a first plane, the plurality of first detection elements 2 are fixed on a second plane parallel to the first plane and are arranged along a motion path of a tail end 12 of the gear shifting rod 1, and a second detection element 3 is arranged at the tail end of the gear shifting rod 1;

The first detection element 2 is a hall sensor, the second detection element 3 is a magnet, and each first detection element 2 has a unique identifier;

the controller switches the gear shift of the vehicle in accordance with the identity of the first detection element 2, which detects the magnetic signal.

In particular, in another embodiment of the invention, a hall sensor may be used as the first detection element 2 and arranged along the movement path of the end 12 of the gear shift lever 1. For example, a plurality of hall sensors H21, H22, H23 may be sequentially disposed on the arc-shaped base 24. The second detecting element 3 is a magnet. The surface of the magnet facing the first detection element 2 may be an S-pole or an N-pole. Each hall sensor H21, H22, H23 has a unique identification. When the hall sensor H22 detects the magnet, the controller is notified to determine that the end 12 of the shift lever 1 is located in the middle. When the hall sensor H21 detects the magnet, the controller is notified, and it is determined that the distal end 12 of the shift lever 1 is located on the left side. When the hall sensor H23 detects the magnet, the controller is notified, and it is determined that the distal end 12 of the shift lever 1 is positioned on the right side.

Fig. 4 shows a flowchart of a method for controlling a hand-gear shifter according to the present invention, which includes:

in step S401, the relative positional relationship between the first detection element 2 and the second detection element 3 is acquired.

In particular, the present invention can be applied to the controller of the aforementioned hand-gear shifter. The controller may be integrated into an Electronic Control Unit (ECU) of the vehicle.

As shown in fig. 2, the gear shift lever 1 rotates around the rotation axis 11, the plurality of first detecting elements 2 are fixed on the second plane which is parallel to the first plane and is arranged along the moving path of the end 12 of the gear shift lever 1, the second detecting element 3 is arranged at the position of the end 12 of the gear shift lever 1, and the rotation of the gear shift lever 1 will drive the second detecting element 2 to pass through different first detecting elements 3.

The relative positional relationship may be output to the controller by the first detecting element 2 or the second detecting element 3, thereby triggering step S401 to acquire the relative positional relationship of the first detecting element 2 and the second detecting element 3.

And S402, acquiring the gear to be selected corresponding to the relative position relation.

Specifically, the relative position relationship and the gear to be selected can be correspondingly stored in a table mode. When the relative position relationship is obtained, the corresponding gear to be selected can be determined through table lookup.
