The engaging member 14 is arranged in the cylindrical portion 13 of the frame 12, so that it can move back and forth integrally with the shift lever 11 and can move up and down along the cylindrical portion 13. The engaging member 14 is biased upward, that is, toward the moderation member 22 by a compression coil spring 15 provided in the cylindrical portion 13.

  The moderation member 22 is a member with which the engagement member 14 is engaged, and is fixed to the lower surface of the cover member 20. As shown in FIG. 2, the moderation member 22 has a plurality of convex portions 23 with which the engagement member 14 engages on a surface facing the engagement member 14.

  Specifically, the moderation member 22 has the first convex portion 23 </ b> A at the intermediate portion between the position corresponding to the D position and the position corresponding to the N position on the movement locus of the engagement member 14 when the shift lever 11 is operated. And has a second convex portion 23B at an intermediate portion between a position corresponding to the N position and a position corresponding to the R position, and a third convex portion at an intermediate portion between the position corresponding to the R position and the position corresponding to the P position. 23C. That is, the moderation member 22 has a detent groove 24 that is recessed from the other part at a position corresponding to each position.

  And the top part 23P of each convex part 23 is arrange | positioned in the center part between two adjacent positions. In the present invention, the top portion is the highest portion of the convex portion 23, and in this embodiment, the top portion is formed in a linear shape extending in a direction orthogonal to the moving direction of the engaging member 14. The top portion may be a flat surface.

  In the moderation mechanism 40, when the shift lever 11 passes through an intermediate portion between two adjacent positions, the engaging member 14 gets over the convex portion 23 while being pressed against the moderation member 22 by the compression coil spring 15, so that the shift lever 11 It is possible to give a load to the operation. Further, when the shift lever 11 is positioned at a predetermined position, the engaging member 14 enters the detent groove 24 so that the position of the shift lever 11 is maintained.

  As shown in FIG. 1, the sensor unit 30 is provided below the lever member 10. The sensor unit 30 includes a rotating member 31 as an example of an interlocking part, an attachment member 32 as an example of a fixing part facing the rotating member 31, and a magnet 33 provided on the rotating member 31 (see FIG. 2). And a magnetic sensor 34 as an example of a first magnetic sensor provided on the attachment member 32.

The attachment member 32 has a through hole 32A in which the shaft portion 12A of the lever member 10 is loosely fitted at the rear end portion. The attachment member 32 has a magnetic sensor 34 fixed to the front end.

  The rotating member 31 is a member provided so as to be interlocked with the movement of the shift lever 11. Specifically, the rotation member 31 is fixed to the shaft portion 12 </ b> A of the lever member 10, and is configured to rotate coaxially with the shift lever 11. The rotating member 31 has an arm portion 31A extending forward from the shaft portion 12A, and a magnet holding portion 31B provided at the tip of the arm portion 31A. And as shown in FIG. 2, the magnet 33 is being fixed to the magnet holding | maintenance part 31B.

  The magnet 33 is arranged such that the S pole and the N pole are shifted in the rotating direction of the rotating member 31. The magnet 33 moves in conjunction with the rotation of the shift lever 11 together with the rotation member 31, thereby moving in the vicinity of the magnetic sensor 34. Accordingly, the magnet 33 applies a magnetic field in a different direction to the magnetic sensor 34 as the shift lever 11 moves between the positions. The arrangement of the S and N poles of the magnet and the positional relationship between the magnet and the magnetic sensor may be adjusted as appropriate so that the output of the magnetic sensor has the characteristics described later.

  The magnetic sensor 34 is a sensor capable of detecting a magnetic field, and is configured to output a voltage corresponding to the magnetic field to the control unit 50. As such a magnetic sensor 34, for example, a giant magnetoresistive element, an anisotropic magnetoresistive element, a Hall element or the like can be adopted.

  Specifically, the magnetic sensor 34 is configured such that the voltage output in response to the direction of the magnetic field vector component acting from the magnet 33 changes. Note that the magnetic sensor 34 may be configured such that the voltage output in response to the strength of the magnetic field working from the magnet 33 changes.

  3A and 3B, in the magnetic sensor 34, the output V increases as the magnet 33 approaches the position corresponding to the N position from the position corresponding to the D position, and the magnet 33 is moved to the N position. The output V increases as it approaches the position corresponding to the R position from the corresponding position, and the output V increases as the magnet 33 approaches the position corresponding to the P position from the position corresponding to the R position. In this embodiment, the output V of the magnetic sensor 34 increases linearly when the magnet 33 moves from a position corresponding to the D position to a position corresponding to the P position.

  As shown in FIG. 4, the control unit 50 is a device that controls each part of the vehicle according to a preset program or the like, and includes a CPU (Central Processing Unit), a RAM (Random Access Memory), and a ROM (Read Only Memory). ) Etc. In addition, the control part 50 may be installed in the housing | casing of the shift lever apparatus 1, may be provided outside the housing | casing of the shift lever apparatus 1, for example, may be installed in the vehicle body.

  The control unit 50 is configured to determine the position of the shift lever 11 based on the output of the magnetic sensor 34, and includes an output voltage acquisition unit 51, a threshold setting unit 52, a position determination unit 53, and a storage unit 54. It has.

  The output voltage acquisition unit 51 is configured to acquire a voltage output from the magnetic sensor 34. Further, the output of the magnetic sensor 34 acquired by the output voltage acquisition means 51 is appropriately stored in the storage unit 54.

  The threshold setting means 52 is configured to set the threshold VT from the change in the output of the magnetic sensor 34 and the current position of the shift lever 11. Specifically, the threshold setting unit 52 includes the output V of the magnetic sensor 34 acquired by the output voltage acquisition unit 51, and the output V of the magnetic sensor 34 previously acquired by the output voltage acquisition unit 51 stored in the storage unit 54. From this, it is determined whether the output V of the magnetic sensor 34 is increasing or decreasing. On the other hand, the threshold setting means 52 obtains the position of the shift lever 11 determined last time stored in the storage unit 54. Then, the threshold setting unit 52 sets the threshold VT with reference to a map as shown in FIG.

  Thereby, when the threshold value setting means 52 determines that the position of the shift lever 11 is the D position when the output V of the magnetic sensor 34 is increasing, the threshold value VT is an example of the first output. Is set to the second voltage V2, and when it is determined that the position of the shift lever 11 is the N position, the threshold VT is set to the fourth voltage V4 as an example of the third output, and the shift lever When it is determined that the 11 position is the R position, the threshold value VT is set to the sixth voltage V6.

  Here, as shown in FIGS. 3A and 3B, the second voltage V <b> 2 is generated when the engaging member 14 is separated from the top 23 </ b> P of the first convex portion 23 </ b> A of the moderation member 22 by a predetermined distance toward the N position. 1 is a voltage output from the magnetic sensor 34 when located at the α1 position as an example of the intermediate position. The fourth voltage V4 is magnetic when the engagement member 14 is located at the α2 position as an example of the third intermediate position that is a predetermined distance away from the top 23P of the second convex portion 23B of the moderation member 22 toward the R position. This is a voltage output from the sensor 34. The sixth voltage V6 is a voltage output from the magnetic sensor 34 when the engaging member 14 is located at the α3 position that is a predetermined distance away from the top 23P of the third convex portion 23C of the moderation member 22 to the P position side. is there.

  In the α1, α2, and α3 positions, when the shift lever 11 is moved from the current position to a position adjacent to the P position side, the engaging member 14 is urged even if the operation of the shift lever 11 is stopped. This position is such that the shift lever 11 naturally moves toward the adjacent position by the biasing force of the compression coil spring 15, and when viewed from the current position, the P position side from the top 23P of the convex portion 23 on the P position side. Is arranged.

  Returning to FIG. 5, when the output V of the magnetic sensor 34 is decreasing, the threshold value setting means 52 outputs the threshold value VT as the second output when it is determined that the position of the shift lever 11 is the N position. Is set to the first voltage V1 as an example, and when it is determined that the position of the shift lever 11 is the R position, the threshold value VT is set to the third voltage V3 as an example of the fourth output, When it is determined that the position of the shift lever 11 is the P position, the threshold value VT is set to the fifth voltage V5.

  Here, as shown in FIGS. 3A and 3B, the first voltage V1 is generated when the engaging member 14 is separated from the top 23P of the first convex portion 23A of the moderation member 22 by a predetermined distance toward the D position. 2 is a voltage output from the magnetic sensor 34 when positioned at the β1 position as an example of the intermediate position. The third voltage V3 is magnetic when the engagement member 14 is located at a position β2 as an example of a fourth intermediate position that is a predetermined distance away from the top 23P of the second convex portion 23B of the moderation member 22 toward the N position. This is a voltage output from the sensor 34. The fifth voltage V5 is a voltage output from the magnetic sensor 34 when the engaging member 14 is located at a position β3 that is a predetermined distance away from the top 23P of the third convex portion 23C of the moderation member 22 toward the R position. is there.

  The β1, β2, and β3 positions bias the engagement member 14 even when the operation of the shift lever 11 is stopped when the shift lever 11 is moved from the current position to a position adjacent to the D position. This position is such that the shift lever 11 naturally moves toward the adjacent position by the biasing force of the compression coil spring 15, and viewed from the current position, the position 23 is located on the D position side from the top 23P of the convex portion 23 on the D position side. Is arranged.

  As shown in FIG. 4, the position determination means 53 determines the position of the shift lever 11 by comparing the output V of the magnetic sensor 34 acquired by the output voltage acquisition means 51 with the threshold value VT set by the threshold setting means 52. Is configured to do. Specifically, when the output V of the magnetic sensor 34 is increasing, the position determination unit 53 determines that the position of the shift lever 11 is changed from the current position when the output V of the magnetic sensor 34 is equal to or greater than the threshold value VT. It determines with having moved to the position adjacent to P position side. Further, when the output V of the magnetic sensor 34 is decreasing, the position determining means 53 determines that the position of the shift lever 11 is changed from the current position to the D position when the output V of the magnetic sensor 34 is equal to or less than the threshold value VT. It is determined that it has moved to a position adjacent to the side. The position determined by the position determination unit 53 is stored in the storage unit 54.

Next, a specific control operation of the control unit 50 will be described with reference to FIG.
When starting the control operation, the controller 50 first determines whether or not the output V of the magnetic sensor 34 has increased (S11).

  If it is determined in step S11 that the output V of the magnetic sensor 34 has increased (S11, Yes), the threshold value setting means 52 sets the threshold value VT (S12). And the control part 50 determines whether the output V of the magnetic sensor 34 is more than the threshold value VT set by step S12 (S13).

  In step S13, if it determines with the output voltage V of the magnetic sensor 34 being more than threshold value VT (S13, Yes), the control part 50 will change the position determination of the shift lever 11 (S14), and will complete | finish control.

  On the other hand, if it is determined in step S13 that the output V of the magnetic sensor 34 is less than the threshold value VT (S13, No), the control unit 50 ends the control without changing the position determination of the shift lever 11.

  If it is determined in step S11 that the output V of the magnetic sensor 34 has not increased (S11, No), the control unit 50 determines whether or not the output V of the magnetic sensor 34 has decreased (S15).

  In Step S15, when it is determined that the output V of the magnetic sensor 34 is decreasing (S15, Yes), the threshold value setting means 52 sets the threshold value VT (S16). And the control part 50 determines whether the output V of the magnetic sensor 34 is below the threshold value VT set by step S16 (S17).

  If it is determined in step S17 that the output V of the magnetic sensor 34 is equal to or less than the threshold value VT (S17, Yes), the control unit 50 changes the position determination of the shift lever 11 (S18) and ends the control.

  On the other hand, if it determines with the output V of the magnetic sensor 34 being larger than the threshold value VT in step S17 (S17, No), the control part 50 will complete | finish control, without changing the position determination of the shift lever 11.

  If it is determined in step S15 that the output V of the magnetic sensor 34 has not decreased (S15, No), the control unit 50 ends the control without changing the position determination of the shift lever 11.

The operation of the shift lever device 1 configured as described above will be described.
Since the output V of the magnetic sensor 34 does not change when the shift lever 11 is held at the D position, the control unit 50 determines that the position of the shift lever 11 is at the D position.

  When the shift lever 11 is moved from the D position toward the N position, the output V of the magnetic sensor 34 increases as shown in FIGS. 3 (a) and 3 (b). At this time, the control unit 50 sets the threshold value VT to the second voltage V2.

  When the shift lever 11 is moved from the D position toward the N position, and the engaging member 14 has not reached the α1 position of the first convex portion 23A, the output V of the magnetic sensor 34 is the second voltage V2. Therefore, the control unit 50 determines that the position of the shift lever 11 is the D position.

  When the engaging member 14 passes the α1 position beyond the top 23P of the first convex portion 23A, the output V of the magnetic sensor 34 becomes equal to or higher than the second voltage V2. As described above, when the control unit 50 determines that the position of the shift lever 11 is the D position, the output V of the magnetic sensor 34 is increased, and the output V of the magnetic sensor 34 is the second voltage. When V2 or higher, the control unit 50 determines that the shift lever 11 has moved from the D position to the N position.

  Since the output V of the magnetic sensor 34 does not change when the shift lever 11 is held at the N position, the control unit 50 determines that the position of the shift lever 11 is the N position.

  When the shift lever 11 is moved from the N position toward the R position, the output V of the magnetic sensor 34 increases. At this time, the control unit 50 sets the threshold value VT to the fourth voltage V4.

  When the shift lever 11 is moved from the N position toward the R position, if the engaging member 14 has not reached the α2 position of the second convex portion 23B, the output V of the magnetic sensor 34 is the fourth voltage V4. Therefore, the control unit 50 determines that the position of the shift lever 11 is the N position.

  When the engaging member 14 passes the α2 position beyond the top 23P of the second convex portion 23B, the output V of the magnetic sensor 34 becomes equal to or higher than the fourth voltage V4. As described above, when the control unit 50 determines that the position of the shift lever 11 is the N position, the output V of the magnetic sensor 34 is increased and the output V of the magnetic sensor 34 is the fourth voltage. When V4 or higher, the control unit 50 determines that the shift lever 11 has moved from the N position to the R position.

  Since the output V of the magnetic sensor 34 does not change when the shift lever 11 is held at the R position, the control unit 50 determines that the position of the shift lever 11 is the R position.

  When the shift lever 11 is moved from the R position toward the P position, the output V of the magnetic sensor 34 increases. At this time, the control unit 50 sets the threshold value VT to the sixth voltage V6.

  When the shift lever 11 is moved from the R position toward the P position, if the engaging member 14 has not reached the α3 position of the third convex portion 23C, the output V of the magnetic sensor 34 is the sixth voltage V6. Therefore, the control unit 50 determines that the position of the shift lever 11 is the R position.

  When the engaging member 14 passes the α3 position beyond the top 23P of the third convex portion 23C, the output V of the magnetic sensor 34 becomes equal to or higher than the sixth voltage V6. As described above, when the control unit 50 determines that the position of the shift lever 11 is the R position, the output V of the magnetic sensor 34 is increased and the output V of the magnetic sensor 34 is the sixth voltage. When V6 or higher, the control unit 50 determines that the shift lever 11 has moved from the R position to the P position.

  Since the output V of the magnetic sensor 34 does not change when the shift lever 11 is held at the P position, the control unit 50 determines that the position of the shift lever 11 is at the P position.

  When the shift lever 11 is moved from the P position toward the R position, the output V of the magnetic sensor 34 decreases. At this time, the control unit 50 sets the threshold value VT to the fifth voltage V5.

  When the shift lever 11 is moved from the P position toward the R position, if the engagement member 14 has not reached the β3 position of the third convex portion 23C, the output V of the magnetic sensor 34 is the fifth voltage V5. Since it is larger, the control unit 50 determines that the position of the shift lever 11 is the P position.

  When the engaging member 14 passes the β3 position beyond the top 23P of the third convex portion 23C, the output V of the magnetic sensor 34 becomes the fifth voltage V5 or less. As described above, when the control unit 50 determines that the position of the shift lever 11 is the P position, the output V of the magnetic sensor 34 is decreased, and the output V of the magnetic sensor 34 is the fifth voltage. When V5 or less, the control unit 50 determines that the shift lever 11 has moved from the P position to the R position.

  When the shift lever 11 is moved from the R position toward the N position, the output V of the magnetic sensor 34 decreases. At this time, the control unit 50 sets the threshold value VT to the third voltage V3.

  When the shift lever 11 is moved from the R position toward the N position, if the engaging member 14 has not reached the β2 position of the second convex portion 23B, the output V of the magnetic sensor 34 is the third voltage V3. Since it is larger, the control unit 50 determines that the position of the shift lever 11 is the R position.

  When the engagement member 14 passes the β2 position beyond the top 23P of the second convex portion 23B, the output V of the magnetic sensor 34 becomes equal to or lower than the third voltage V3. As described above, when the control unit 50 determines that the position of the shift lever 11 is the R position, the output V of the magnetic sensor 34 is decreased, and the output V of the magnetic sensor 34 is the third voltage. When V3 or less, the control unit 50 determines that the shift lever 11 has moved from the R position to the N position.

  When the shift lever 11 is moved from the N position toward the D position, the output V of the magnetic sensor 34 decreases. At this time, the control unit 50 sets the threshold value VT to the first voltage V1.

  When the shift lever 11 is moved from the N position toward the D position, if the engagement member 14 has not reached the β1 position of the first convex portion 23A, the output V of the magnetic sensor 34 is the first voltage V1. Since it is larger, the control unit 50 determines that the position of the shift lever 11 is the N position.

  When the engagement member 14 passes the position β1 beyond the top 23P of the first convex portion 23A, the output V of the magnetic sensor 34 becomes equal to or less than the first voltage V1. As described above, when the control unit 50 determines that the position of the shift lever 11 is the N position, the output V of the magnetic sensor 34 is decreased, and the output V of the magnetic sensor 34 is the first voltage. When V1 or less, the control unit 50 determines that the shift lever 11 has moved from the N position to the D position.

  The effect of the shift lever device 1 in the present embodiment configured as described above will be described.

  In the shift lever device 1, when the shift lever 11 is moved between two adjacent positions, after the engaging member 14 gets over the top 23P of the convex portion 23 corresponding to the two positions, the shift lever 11 If the shift lever 11 naturally moves to the next position even after the operation of 11 is stopped, the position determination of the shift lever 11 determined by the control unit 50 is switched. Thereby, the control part 50 can perform the determination suitable for the operational feeling by the moderation mechanism 40. FIG. A change in the output V of the magnetic sensor 34 accompanying the movement of the shift lever 11 is also used for position determination, so that a highly reliable determination result can be obtained.

  In this embodiment, the movement of the shift lever 11 to the P position side and the movement to the D position side can be determined using one magnetic sensor 34. Further, the four positions of the shift lever 11 can be determined using one magnetic sensor 34. Thereby, cost can be reduced.

  Further, in the shift lever device 1, the rotating member 31 to which the magnet 33 is fixed is configured to rotate coaxially with the shift lever 11, so that the magnet is moved as the shift lever 11 rotates. Compared to a configuration in which the magnetic sensor slides, the configuration of the shift lever device 1 can be simplified and downsized.

[Second Embodiment]
Next, a second embodiment of the present invention will be described in detail with reference to the drawings as appropriate. In the shift lever device according to the second embodiment, as shown in FIGS. 7A and 7B, a shift lever is used by using two magnetic sensors, ie, a first magnetic sensor and a second magnetic sensor, having different output change tendencies. The position is determined. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The first magnetic sensor and the second magnetic sensor are fixed to the mounting member 32 of the sensor unit 30 (see FIG. 1), and control the voltage as shown in FIG. 7B by detecting the magnetic field acting from the magnet 33. It is configured to output to the unit 50.

  Specifically, in the first magnetic sensor, similarly to the magnetic sensor 34 of the first embodiment, the output VA increases as the magnet 33 approaches the position corresponding to the N position from the position corresponding to the D position. The output VA increases as the position corresponding to the R position approaches from the position corresponding to the N position, and the output VA increases as the magnet 33 approaches the position corresponding to the P position from the position corresponding to the R position. ing.

  In the second magnetic sensor, the output VB increases as the magnet 33 approaches the position corresponding to the R position from the position corresponding to the P position, and as the magnet 33 approaches the position corresponding to the N position from the position corresponding to the R position. The output VB increases, and the output VB increases as the magnet 33 approaches the position corresponding to the D position from the position corresponding to the N position.

  The threshold setting means 52 of the control unit 50 determines whether the magnetic sensor whose output V is increasing is the first magnetic sensor or the second magnetic sensor, and the determination result and the current position of the shift lever 11. The threshold value VT is set with reference to a map as shown in FIG.

  Thereby, when the output VA of the first magnetic sensor is increasing and the threshold value setting means 52 determines that the position of the shift lever 11 is the D position, the threshold value setting means 52 sets the threshold value VT to the first output. If the seventh voltage V7 is set as an example and it is determined that the position of the shift lever 11 is the N position, the threshold VT is set to the eighth voltage V8 as an example of the third output, and the shift is performed. When it is determined that the position of the lever 11 is the R position, the threshold value VT is set to the ninth voltage V9.

  Further, when the threshold value setting unit 52 determines that the position of the shift lever 11 is the N position when the output VB of the second magnetic sensor is increasing, the threshold value VT is an example of the fifth output. Is set to the ninth voltage V9, and when it is determined that the position of the shift lever 11 is the R position, the threshold VT is set to the eighth voltage V8 as an example of the sixth output, and the shift lever When it is determined that the 11 position is the P position, the threshold value VT is set to the seventh voltage V7.

  Here, as shown in FIGS. 7A and 7B, the seventh voltage V7 is output from the first magnetic sensor when the engaging member 14 is located at the α1 position of the first convex portion 23A of the moderation member 22. And the voltage output from the second magnetic sensor when the engaging member 14 is located at the β3 position of the third convex portion 23C of the moderation member 22. The eighth voltage V8 is a voltage output from the first magnetic sensor when the engaging member 14 is located at the α2 position of the second convex portion 23B of the moderation member 22, and the eighth voltage V8 is the moderation member 22 This is a voltage output from the second magnetic sensor when it is located at the β2 position of the second convex portion 23B. The ninth voltage V9 is a voltage output from the first magnetic sensor when the engagement member 14 is positioned at the α3 position of the third convex portion 23C of the moderation member 22, and the engagement member 14 is the moderation member 22. This voltage is output from the second magnetic sensor when it is located at the β1 position of the first convex portion 23A.

  In this embodiment, the output VA of the first magnetic sensor when the engaging member 14 is located at the α1 position and the output VB of the second magnetic sensor when the engaging member 14 is located at the β3 position are the same. However, the first magnetic sensor and the second magnetic sensor may be configured to have different outputs. Similarly, the output VA of the first magnetic sensor when the engaging member 14 is located at the α2 position may be different from the output VB of the second magnetic sensor when the engaging member 14 is located at the β2 position. The output VA of the first magnetic sensor when the engaging member 14 is located at the α3 position may be different from the output VB of the second magnetic sensor when the engaging member 14 is located at the β1 position.

  The position determination unit 53 determines the position of the shift lever 11 by comparing the output V of the magnetic sensor whose output acquired by the output voltage acquisition unit 51 is increasing with the threshold value VT set by the threshold setting unit 52. Is configured to do.

  Next, a specific control operation of the control unit 50 in the present embodiment will be described with reference to FIG.

  When starting the control operation, the controller 50 first determines whether or not the output VA of the first magnetic sensor is increasing (S21). If it is determined in step S21 that the output VA of the first magnetic sensor is increasing (S21, Yes), the threshold setting unit 52 sets the threshold VT (S22). And the control part 50 determines whether the output VA of a 1st magnetic sensor is more than threshold value VT (S23).

  If it is determined in step S23 that the output VA of the first magnetic sensor is greater than or equal to the threshold value VT (S23, Yes), the control unit 50 changes the position determination of the shift lever 11 (S24) and ends the control.

  On the other hand, if it is determined in step S23 that the output VA of the first magnetic sensor is less than the threshold value VT (S23, No), the control unit 50 ends the control without changing the position determination of the shift lever 11.

  If it is determined in step S21 that the output VA of the first magnetic sensor has not increased (S21, No), the control unit 50 determines whether or not the output VB of the second magnetic sensor has increased (S25). .

  If it is determined in step S25 that the output VB of the second magnetic sensor is increasing (S25, Yes), the threshold setting means 52 sets the threshold VT (S26). And the control part 50 determines whether the output VB of a 2nd magnetic sensor is more than threshold value VT (S27).

  If it determines with the output VB of a 2nd magnetic sensor being more than threshold value VT in step S27 (S27, Yes), the control part 50 will change the position determination of the shift lever 11 (S28), and will complete | finish control.

  On the other hand, when it is determined in step S27 that the output VB of the second magnetic sensor is smaller than the threshold value VT (S27, No), the control unit 50 ends the control without changing the position determination of the shift lever 11.

  If it determines with the output VB of a 2nd magnetic sensor not increasing in step S25 (S25, No), the control part 50 will complete | finish control, without changing the position determination of the shift lever 11. FIG.

Since it is less than V7, the control unit 50 determines that the position of the shift lever 11 is the D position.

  Then, when the engaging member 14 passes the α1 position beyond the top 23P of the first convex portion 23A, the output VA of the first magnetic sensor becomes equal to or higher than the seventh voltage V7. As described above, when the control unit 50 determines that the position of the shift lever 11 is the D position, the output VA of the first magnetic sensor is increased and the output VA of the first magnetic sensor is the first. When the voltage becomes equal to or higher than 7 voltage V7, the control unit 50 determines that the shift lever 11 has moved from the D position to the N position.

  Since the outputs VA and VB of the first magnetic sensor and the second magnetic sensor do not change when the shift lever 11 is held at the N position, the control unit 50 determines that the position of the shift lever 11 is the N position. .

  When the shift lever 11 is moved from the N position toward the R position, the output VA of the first magnetic sensor increases and the output VB of the second magnetic sensor decreases. At this time, the control unit 50 sets the threshold value VT to the eighth voltage V8.

Since it is less than V8, the control unit 50 determines that the position of the shift lever 11 is the N position.

  When the engaging member 14 passes the α2 position beyond the top 23P of the second convex portion 23B, the output V of the first magnetic sensor becomes equal to or higher than the eighth voltage V8. As described above, when the control unit 50 determines that the position of the shift lever 11 is the N position, the output V of the magnetic sensor 34 is increased, and the output V of the magnetic sensor 34 is the eighth voltage. When V8 or higher, the control unit 50 determines that the shift lever 11 has moved from the N position to the R position.

  Since the outputs VA and VB of the first magnetic sensor and the second magnetic sensor do not change when the shift lever 11 is held at the R position, the control unit 50 determines that the position of the shift lever 11 is the R position. .

  When the shift lever 11 is moved from the R position toward the P position, the output VA of the first magnetic sensor increases and the output VB of the second magnetic sensor decreases. At this time, the control unit 50 sets the threshold value VT to the ninth voltage V9.

  When the shift lever 11 is moved from the R position toward the P position, if the engaging member 14 has not reached the α3 position of the third convex portion 23C, the output VA of the first magnetic sensor is the ninth voltage. Since it is less than V9, the control unit 50 determines that the position of the shift lever 11 is the R position.

  When the engagement member 14 passes the α3 position beyond the top 23P of the third convex portion 23C, the output VA of the first magnetic sensor becomes equal to or higher than the ninth voltage V9. As described above, when the control unit 50 determines that the position of the shift lever 11 is the R position, the output VA of the first magnetic sensor is increased and the output VA of the first magnetic sensor is the first. When it becomes 9 voltage V9 or more, the control unit 50 determines that the shift lever 11 has moved from the R position to the P position.

  Since the outputs VA and VB of the first magnetic sensor and the second magnetic sensor do not change when the shift lever 11 is held at the P position, the control unit 50 determines that the position of the shift lever 11 is the P position. .

  When the shift lever 11 is moved from the P position toward the R position, the output VB of the second magnetic sensor increases and the output VA of the first magnetic sensor decreases. At this time, the control unit 50 sets the threshold value VT to the seventh voltage V7.

  When the shift lever 11 is moved from the P position toward the R position, if the engaging member 14 has not reached the β3 position of the third convex portion 23C, the output VB of the second magnetic sensor is the seventh voltage. Since it is smaller than V7, the controller 50 determines that the position of the shift lever 11 is the P position.

  When the engaging member 14 passes the β3 position beyond the top 23P of the third convex portion 23C, the output VB of the second magnetic sensor becomes equal to or higher than the seventh voltage V7. As described above, when the control unit 50 determines that the position of the shift lever 11 is the P position, the output VB of the second magnetic sensor is increased and the output VB of the second magnetic sensor is the first. When the voltage becomes equal to or higher than 7 voltage V7, the control unit 50 determines that the shift lever 11 has moved from the P position to the R position.

  When the shift lever 11 is moved from the R position toward the N position, the output VB of the second magnetic sensor increases and the output VA of the first magnetic sensor decreases. At this time, the control unit 50 sets the threshold value VT to the eighth voltage V8.

  When the shift lever 11 is moved from the R position toward the N position, if the engaging member 14 has not reached the β2 position of the second convex portion 23B, the output VB of the second magnetic sensor is the eighth voltage. Since it is smaller than V8, the controller 50 determines that the position of the shift lever 11 is the R position.

  When the engaging member 14 passes the position β2 beyond the top 23P of the second convex portion 23B, the output VB of the second magnetic sensor becomes equal to or higher than the eighth voltage V8. Thus, when the control unit 50 determines that the position of the shift lever 11 is the R position, the output VB of the second magnetic sensor is decreased and the output VB of the second magnetic sensor is the first. When the voltage is equal to or higher than 8 voltage V8, the control unit 50 determines that the shift lever 11 has moved from the R position to the N position.

  When the shift lever 11 is moved from the N position toward the D position, if the engaging member 14 has not reached the β1 position of the first convex portion 23A, the output VB of the second magnetic sensor is the ninth voltage. Since it is larger than V9, the control unit 50 determines that the position of the shift lever 11 is the N position.

  When the engaging member 14 passes the position β1 beyond the top 23P of the first convex portion 23A, the output VB of the second magnetic sensor becomes equal to or lower than the ninth voltage V9. Thus, when the control unit 50 determines that the position of the shift lever 11 is the N position, the output VB of the second magnetic sensor is increased and the output VB of the second magnetic sensor is the first. When the voltage becomes 9 voltage V9 or more, the control unit 50 determines that the shift lever 11 has moved from the N position to the D position.

  Also in the shift lever device 1 according to the present embodiment configured as described above, the control unit 50 can make a determination according to the operational feeling of the moderation mechanism 40. And the change result of the output of the first magnetic sensor and the second magnetic sensor accompanying the movement of the shift lever 11 is also used for the position determination, so that a highly reliable determination result can be obtained.

  Further, since the movement from the D position side to the P position side is detected by the first magnetic sensor and the movement from the P position side to the D position side is detected by the second magnetic sensor, the shift lever 11 is A difference between a plurality of thresholds for determining the position can be increased. Thereby, a highly accurate position determination result can be obtained.

  In addition, when the output of the magnetic sensor has a different behavior when it increases and when it decreases, that is, when it shows hysteresis, the output when the first magnetic sensor or the second magnetic sensor increases as in this embodiment. By using only this, a highly accurate detection result can be obtained.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment. About a concrete structure, it can change suitably in the range which does not deviate from the meaning of this invention.

  In the second embodiment described above, the control unit 50 sets the threshold value VT based on the output of the magnetic sensor whose output increases among the two magnetic sensors, and whether the output of the magnetic sensor exceeds the threshold value. Although it has been configured to determine the position of the shift lever 11 by determining whether or not, the configuration of the control unit 50 is not limited to this. For example, as shown in FIGS. 10A and 10B, the threshold value VT is set based on the output of the magnetic sensor whose output decreases among the two magnetic sensors, and the output V of the magnetic sensor is set to the threshold value VT. You may comprise so that the position of the shift lever 11 may be determined by determining whether it became below.

An eleventh voltage V11 as an example of a ninth output is output when positioned at the α2 position of 23B, and a tenth voltage V10 is output when the engaging member 14 is positioned at the α3 position of the third convex portion 23C. It is configured.

  In the fourth magnetic sensor, the output VD decreases as the magnet 33 approaches the position corresponding to the R position from the position corresponding to the P position, and as the magnet 33 approaches the position corresponding to the N position from the position corresponding to the R position. The output VD decreases, and the output VD decreases as the magnet 33 approaches the position corresponding to the D position from the position corresponding to the N position.

When it becomes below, it determines with the position of the shift lever 11 having moved from D position to N position. Further, when the control unit 50 determines that the position of the shift lever 11 is the N position, the output VC of the third magnetic sensor is decreased and the output VC of the third magnetic sensor is the eleventh. When the voltage is equal to or lower than V11, it is determined that the position of the shift lever 11 has moved from the N position to the R position. Then, when the control unit 50 determines that the position of the shift lever 11 is the R position, the output VC of the third magnetic sensor is decreased and the output VC of the third magnetic sensor is the tenth. When the voltage is equal to or lower than V10, it is determined that the position of the shift lever 11 has moved from the R position to the P position.
