Description

  The present invention relates to a shift position notification device that notifies a shift position of a shift lever that is movable in a predetermined direction.

  Conventionally, a configuration has been provided in which the behavior of a vehicle is switched by moving (switching) a shift lever to a plurality of shift positions such as a parking position, a reverse position, a neutral position, and a drive position. In this type of configuration, an operation error (misunderstanding) of the shift lever may cause a behavior that is not assumed by the user. For example, it may be assumed that the shift lever is moved to the drive position even though the shift lever is actually moved to the second position in order to apply the engine brake when going down a hill. Further, for example, it may be assumed that the shift lever is moved to the drive position even though the shift lever is actually moved to the neutral position, and the accelerator is operated (blank). Under such circumstances, a configuration for notifying the shift position of the shift lever by sound is disclosed (see, for example, Patent Documents 1 and 2).

Japanese Utility Model Publication No. 03-28924 Japanese Patent Laid-Open No. 01-12924

  From Patent Documents 1 and 2, by providing sensors corresponding to all the shift positions, a configuration can be conceived in which, even when the shift lever is moved to any shift position, the shift position is notified by sound. However, in the configuration in which sensors are provided corresponding to all shift positions, there are problems such as an increase in the number of parts and a complicated configuration. There is also a problem that the shift lever cannot be applied (so-called retrofitting) to the existing configuration assembled to the case.

  Therefore, the applicant can appropriately notify all shift positions with sound without complicating the configuration, and as a shift position notification device that can be easily applied to the existing configuration, Patent application 2012-178215 was filed. In Japanese Patent Application No. 2012-178215, infrared light (light) is irradiated from the light projecting unit toward the shift lever, and light reflected from the shift lever (reflected light) is detected by a PSD (Position Sensitive Detector) of the light receiving unit. Ranging means for measuring the distance to the shift lever by outputting an output voltage corresponding to the distance up to is used. For example, when the shift position notification device is mounted, the measurement value measured by the distance measurement unit corresponding to each shift position is stored as a stored value, and the measurement value measured by the distance measurement unit thereafter is stored as the stored value. To determine the shift position of the shift lever.

  However, such a distance measuring means using PSD increases the output voltage as the distance to the object increases in a region where the distance to the object to be detected is less than a predetermined distance (a sufficiently short region). In the region where the distance to the object is a predetermined distance or more, the output voltage decreases as the distance to the object increases. Further, the output voltage decreases asymptotically in the region where the output voltage decreases. For these reasons, depending on the mounting position (mounting position) of the shift position notification device, the stored values of adjacent shift positions may be close (the difference is extremely small), and it is difficult to accurately identify the shift position. There is a risk of becoming.

  The present invention has been made in view of the above-described circumstances, and a purpose thereof is to provide a shift position notifying device for a shift lever that can appropriately notify a user whether or not the mounting position of the shift position notifying device is appropriate. Is to provide.

  According to the invention described in claim 1, the distance measuring means measures the physical quantity obtained by measuring the distance to the shift lever movable in a predetermined direction, and the distance to the shift lever is less than the predetermined distance. In the region, the output is output with an output characteristic that increases as the distance to the shift lever increases and decreases in the region of a predetermined distance or more as the distance to the shift lever increases. The storage means stores the physical quantity acquired by the distance measuring means corresponding to each shift position of the shift lever as a plurality of stored values. The shift position specifying means specifies the shift position of the shift lever based on the physical quantity acquired by the distance measuring means and a plurality of stored values stored in the storage means. The notification sound output control means causes the notification sound output means to output a notification sound that can specify the shift position of the shift lever specified by the shift position specification means. Here, the warning output control means warns that the difference between the first stored value corresponding to the first shift position and the second stored value corresponding to the second shift position is less than a specified value. Output from the output means.

  If the first shift position and the second shift position are not in a relationship that sandwiches the peak of the output characteristic of the distance measuring means (the point at which the physical quantity increases or decreases), the first stored value and the second stored value Is less likely to be less than the specified value, but if the first shift position and the second shift position sandwich the output characteristic peak of the distance measuring means, the difference is less than the specified value. Is likely to be. If the difference between the first stored value and the second stored value is less than the specified value, it may be difficult to specify the shift position of the shift lever. Therefore, by outputting a warning when the difference between the first stored value and the second stored value is less than the specified value, it is difficult to specify the shift position with the current mounting position, It is possible to appropriately notify the user that the mounting position of is not appropriate.

  According to the second aspect of the present invention, the distance measuring means asymptotically obtains the physical quantity obtained by measuring the distance to the shift lever movable in a predetermined direction as the distance to the shift lever increases. Output with decreasing output characteristics. The storage means stores the physical quantity acquired by the distance measuring means corresponding to each shift position of the shift lever as a plurality of stored values. The shift position specifying means specifies the shift position of the shift lever based on the physical quantity acquired by the distance measuring means and a plurality of stored values stored in the storage means. The notification sound output control means causes the notification sound output means to output a notification sound that can specify the shift position of the shift lever specified by the shift position specification means. Here, the warning output control means warns that the difference between the first stored value corresponding to the first shift position and the second stored value corresponding to the second shift position is less than a specified value. Output from the output means.

  If the first stored value and the second stored value are sufficiently far from the asymptote (if separated from each other), the difference between the first stored value and the second stored value may be less than the specified value. Low, but if not far enough from the asymptote (if not far away), the difference is likely to be less than the specified value. If the difference between the first stored value and the second stored value is less than the specified value, it may be difficult to specify the shift position of the shift lever. Therefore, by outputting a warning when the difference between the first stored value and the second stored value is less than the specified value, the current mounting position remains the same as in the first aspect of the invention described above. Therefore, it is difficult to specify the shift position, and it is possible to appropriately notify the user that the current mounting position is not appropriate.

(First embodiment)
Hereinafter, a first embodiment applied to a shift lever disposed on a floor in a vehicle interior will be described with reference to FIGS. 1 to 15. As shown in FIG. 2, a center console 3 is installed between the driver's seat 1 (right-hand drive vehicle) and the passenger seat 2 in the passenger compartment of the automobile. A shift lever 4 for changing the shift position of the automatic transmission is provided upright on the upper surface portion 3 a of the center console 3. The shift position notifying device 5 of the shift lever 4 has a rectangular housing 6, and is located on the vehicle front side (instrument panel (not shown) side) as viewed from the shift lever 4 on the upper surface 3 a of the center console 3. Installed (installed).

  As an aspect with which the shift position alerting | reporting apparatus 5 is mounted | worn with the upper surface part 3a of the center console 3, there exist the aspect adhere | attached with an adhesive tape, the aspect fixed with a screw, etc., for example. The mode of being bonded by the adhesive tape has an advantage that it can be easily attached and detached while having an appropriate adhesive strength. On the other hand, the screwed mode requires an effort to attach and detach, but has an advantage that it can be securely fixed. The user (occupants including the driver) may select which mode to mount the shift position notification device 5 according to the usage pattern of the shift position notification device 5. That is, if there is a high possibility that the shift position notification device 5 will be used in another vehicle (for example, a private vehicle and a vehicle used for work, etc.) Adhere. On the other hand, if there is a low possibility of using the shift position notification device 5 in another vehicle, it is preferable to screw it with priority on reliable fixing.

  The shift lever 4 includes a grip portion 7 that can be gripped by the user, and a shaft portion 8 that supports the grip portion 7, and is movable linearly in the front-rear direction (predetermined direction) of the vehicle (operation). Possible). As shift positions at which the shift lever 4 can move, six positions are set from the front side to the rear side of the vehicle: a parking position, a reverse position, a neutral position, a drive position, a second position, and a low position. The user can move the shift lever 4 in the front-rear direction of the vehicle by holding the grip portion 7 and releasing the movement restriction (lock) by operating the lock release button 4a as necessary. The shift position of the lever 4 can be arbitrarily changed (shift change is possible). Further, on the upper surface portion 3a of the center console 3, nine and six character portions indicating "P", "R", "N", "D", "2", "L" corresponding to each shift position are provided. The window portion 10 is provided along the movement direction of the shift lever 4. The window portion 10 corresponding to the shift position where the shift lever 4 is moved is visually distinguished from the other window portions 10.

  The shift position notification device 5 is configured such that a power source (predetermined voltage power) is supplied from the cigarette lighter socket 11 by attaching a power source connection portion 12 to a cigarette lighter socket 11 serving as a vehicle-side power source installed in the passenger compartment of the automobile. It is supplied via the power line 13. That is, the shift position notification device 5 is turned on following the fact that the Acc switch is turned on and power is supplied from the vehicle battery (not shown) to the cigarette lighter socket 11. The shift position notification device 5 may be supplied with power from an Acc (accessory) switch or an IG (ignition) switch.

  As shown in FIG. 1, the shift position notification device 5 includes a first power supply unit (first regulator) 14, a second power supply unit (second regulator) 15, and a distance measuring sensor 16 (corresponding to distance measuring means). ), A microcomputer (hereinafter referred to as a microcomputer) 17, a speaker 18 (corresponding to a notification sound output means and a warning output means), and a setting switch 19. The first power supply unit 14 steps down the electric power of a predetermined voltage supplied from the cigarette lighter socket 11 via the power supply line 13 to the first constant voltage and supplies it to the distance measuring sensor 16 and the microcomputer 17. The second power supply unit 15 steps down the power of a predetermined voltage supplied from the cigarette lighter socket 11 via the power supply line 13 to a second constant voltage and supplies it to the speaker 18 with a built-in amplifier.

  The distance measuring sensor 16 operates using power of a first constant voltage supplied from the first power supply unit 14 as operating power. As shown in FIG. 3, the distance measuring sensor 16 includes a light emitting unit 20 and a light receiving unit 21, and irradiates infrared rays (light) from the light emitting unit 20 toward an object that is a detection target. The light (reflected light) reflected by is detected by a PSD (Position Sensitive Detector) of the light receiving unit 21, and a voltage signal (output voltage as a physical quantity) corresponding to the distance from the distance measuring sensor 16 to the object is output. FIG. 4 shows the relationship between the output voltage of the distance measuring sensor 16 and the distance from the distance measuring sensor 16 to the object, and shows an example of the waveform of the output voltage of the distance measuring sensor 16. As can be seen from FIG. 4, the output voltage of the distance measuring sensor 16 increases as the distance to the object increases in the region where the distance to the object is less than a predetermined distance (about 5 cm in FIG. 4). In an area where the distance is greater than or equal to a predetermined distance, asymptotically decreases as the distance to the object increases. That is, in a region where the distance to the object is equal to or greater than a predetermined distance, the distance from the distance measuring sensor 16 to the object and the output voltage of the distance measuring sensor 16 have a corresponding relationship. Note that the region (detection region) where the output voltage of the distance measuring sensor 16 decreases asymptotically varies depending on the specifications of the distance measuring sensor 16.

  In this embodiment, as shown in FIGS. 2 and 5, the light emitting unit 20 and the light receiving unit 21 of the distance measuring sensor 16 are irradiated from the light emitting unit 20 so as to be on the extension line of the movement locus of the shift lever 4. Since the shift position notification device 5 is mounted so that the optical axis of the infrared light that follows the movement locus of the shift lever 4 and the detection target that irradiates the infrared light is the shift lever 4, the distance measuring sensor 16 is the shift lever 4. A voltage signal corresponding to the distance to is output. That is, when the shift lever 4 is moved by using the detection area of the distance measuring sensor 16, the distance from the distance measuring sensor 16 to the shift lever 4 changes, and the output voltage follows the change in the distance. Therefore, the shift position of the shift lever 4 can be detected by detecting the change in the output voltage.

  When the intensity of the reflected light from the shift lever 4 is weak (the light receiving level has not reached a predetermined level), a reflection member may be attached to the shift lever 4 to increase the reflectance. The light emitting unit 20 and the light receiving unit 21 may be mounted so as to be aligned in the horizontal direction, or the light emitting unit 20 and the light receiving unit 21 may be mounted so as to be aligned in the vertical direction (the same direction as the axial direction of the shaft unit 8). May be. Further, the distance measuring sensor 16 may be any sensor as long as it can measure the distance to the shift lever 4 and output a physical quantity indicating the measured distance to the microcomputer 17, for example, an ultrasonic wave or a radar. The sensor etc. which measure the round-trip time of light, such as, may be sufficient.

  The microcomputer 17 receives a voltage signal from a controller 22 (corresponding to a shift position specifying means, a notification sound output control means, a warning output control means, and a recommended correction amount calculation means) that is a microcomputer body that performs various controls. It has an A / D converter 23, a non-volatile memory 24 for data storage (corresponding to storage means), and a speech synthesizer 25 that synthesizes speech. The controller 22 executes a control program stored in advance to control the overall operation of the shift position notification device 5. When the voltage signal is input from the distance measuring sensor 16, the A / D converter 23 converts the input voltage signal from an analog signal to a digital signal and outputs it to the controller 22. The non-volatile memory 24 has a storage area capable of storing the relationship between the output voltage of the distance measuring sensor 16 and the shift position of the shift lever 4 in a state where the shift position notification device 5 is mounted. The non-volatile memory 24 has a storage area capable of storing setting information of various flags including a stored value stored flag which will be described later.

  When the voice synthesis unit 25 receives a synthesis command from the controller 22, the voice synthesis unit 25 synthesizes voice according to the inputted synthesis command to generate a voice signal, and outputs the generated voice signal to the speaker 18. The speaker 18 is driven when a voice signal is input from the voice synthesizer 25, and utters a voice corresponding to the voice signal input from the voice synthesizer 25. The speaker 18 is provided on the upper surface portion 6a of the housing 6 so that the spoken voice can be easily heard by the user.

  The setting switch 19 is a switch that can be operated by the user, and outputs an operation detection signal to the controller 22 when a user operation is detected. The setting switch 19 is provided on the upper surface portion 6a of the housing 6 in the same manner as the speaker 18 so as to receive an operation from the user from the upper side. The setting switch 19 is preferably enabled on condition that the user presses and holds the button for a long time (an operation exceeding a predetermined continuous time) in order to prevent a user's erroneous operation. The setting switch 19 may be provided on the side surface of the housing 6.

  Here, the relationship between the output voltage of the distance measuring sensor 16 and the shift position of the shift lever 4 will be described. The movement range of the shift lever 4 (the distance between “P (parking position)” and “L (low position)” which is the shift position at both ends) and the mounting position (shift position) of the shift position notification device 5 with respect to the shift lever 4 The distance from the notification device 5 to “P”, which is the nearest shift position, varies depending on the type of vehicle, the size and shape of the center console 3, and the like. Therefore, the output voltage of the distance measuring sensor 16 differs depending on the movement range of the shift lever 4 and the mounting position of the shift position notification device 5 with respect to the shift lever 4. More specifically, as shown in FIGS. 6 and 7, the mounting position of the shift position notification device 5 with respect to the shift lever 4 is the same, but the movement range of the shift lever 4 is different (a) and (b). Then, the difference in the output voltage increases as the distance from the distance measuring sensor 16 becomes longer (the shift position goes to “L”) ((a) in FIG. 7 is indicated by a solid line, (b) ) Is indicated by a broken line).

  Further, in the cases (a) and (c) in which the shift lever 4 is mounted on the shift lever 4 at different positions while the shift lever 4 has the same movement range, the shift lever 4 is output regardless of the distance from the distance measuring sensor 16. The voltage difference is substantially constant (in FIG. 7, (a) is indicated by a solid line and (c) is indicated by a one-dot chain line). Thus, even if the shift position of the shift lever 4 is the same, the output voltage of the distance measuring sensor 16 is the movement range of the shift lever 4 and the mounting position of the shift position notification device 5 with respect to the shift lever 4, that is, the type of vehicle. Depends on the size and shape of the center console 3, etc. Under such circumstances, the relationship between the output voltage of the distance measuring sensor 16 and the shift position of the shift lever 4 when the shift position notification device 5 is mounted as described above can be stored in the nonvolatile memory 24 (learnable). It has become.

  In the configuration described above, the controller 22 stores the measured value of the output voltage measured by the distance measuring sensor 16 corresponding to each shift position when the shift position notification device 5 is mounted in the nonvolatile memory 24 as a stored value. Then, the shift position of the shift lever 4 is specified by comparing the measured value of the output voltage measured by the distance measuring sensor 16 with the determination area corresponding to the stored value. More specifically, the controller 22 stores “Vp” as the stored value of the output voltage at the parking position, “Vr” as the stored value of the output voltage at the reverse position, “Vn” as the stored value of the output voltage at the neutral position, and the drive. If the stored value of the output voltage at the position is “Vd”, the stored value of the output voltage at the second position is “V2”, and the stored value of the output voltage at the low position is “Vl”, a constant (constant) is set for each stored value. The multiplied value is calculated and stored as a determination area.

That is, as shown in FIG. 8, the controller 22 uses Vp ± Vp × kp% (kp is a predetermined constant) as a parking position determination area and Vr ± Vr × kr% (kr is a predetermined constant) as a reverse position. Vn ± Vn × kn% (kn is a predetermined constant) is a neutral position determination region, Vd ± Vd × kd% (kd is a predetermined constant) is a drive position determination region, and V2 ± V2 Xk2% (k2 is a predetermined constant) is used as the second position determination area, and V1 ± V1 × kl% (k1 is a predetermined constant) is calculated and stored as the low position determination area. Then, the controller 22 sets the measured value of the output voltage of the distance measuring sensor 16 to “V”.
Vp−Vp × kp% ≦ V ≦ Vp + Vp × kp%
To determine that the shift lever 4 is in the parking position,
Vr−Vr × kr% ≦ V ≦ Vr + Vr × kr%
To determine that the shift lever 4 is in the reverse position,
Vn−Vn × kn% ≦ V ≦ Vn + Vn × kn%
To determine that the shift lever 4 is in the neutral position,
Vd−Vd × kd% ≦ V ≦ Vd + Vd × kd%
To determine that the shift lever 4 is in the drive position,
V2−V2 × k2% ≦ V ≦ V2 + V2 × k2%
To determine that the shift lever 4 is in the second position,
Vl−Vl × kl% ≦ V ≦ Vl + Vl × kl%
To determine that the shift lever 4 is in the low position.

  Here, in the method of specifying the shift position in this way, when attention is paid to the stored value of each shift position, the difference between any two (for example, adjacent) stored values is equal to or larger than a predetermined value, and is sufficiently secured. If this is done, it is possible to specify the shift position of the shift lever 4 without overlapping the determination areas of the stored values. However, if the difference between any two stored values is not greater than or equal to the specified value (below the specified value) and is not sufficiently secured, there is a possibility that the determination areas of these stored values overlap, It may be difficult to specify the shift position.

  That is, as shown in FIG. 4, the distance measuring sensor 16 increases as the distance to the shift lever 4 increases in a region where the distance to the shift lever 4 is less than the predetermined distance, and the distance to the shift lever 4 is predetermined. Since the region above the distance has an output characteristic that decreases asymptotically as the distance to the shift lever 4 increases, the region in which the shift position can be specified is limited. Specifically, as shown in FIG. 9, if all the stored values are regions where the output voltage of the distance measuring sensor 16 is asymptotically reduced and the stored value of the parking position is close to the peak, all stored values are stored. There is a high possibility that the difference between the stored values is equal to or greater than the specified value, and there is a high possibility that the shift position of the shift lever 4 can be specified appropriately.

  On the other hand, as shown in FIG. 10 and FIG. 11, if any stored value is an area that sandwiches a peak, the difference between the stored values of the area that sandwiches the peak (ΔVpr = Vp−Vr in FIGS. 10 and 11). ) Is less than the specified value, and it is unlikely that the shift position at which the difference between the stored values is less than the specified value can be accurately specified. In addition, as shown in FIG. 12, all the stored values are areas where the output voltage of the distance measuring sensor 16 is asymptotically reduced, but if the stored value of the parking position is far from the peak, the stored values of the area far from the peak are stored. It is highly possible that the difference between them (ΔVpr = Vp−Vr in FIG. 12) is less than the specified value, and all shift positions including the shift position where the difference between the stored values is less than the specified value can be accurately specified. Is unlikely. In consideration of such circumstances, the controller 22 of the microcomputer 17 performs the processing described below.

Next, the operation of the above configuration will be described with reference to FIGS. The controller 22 of the microcomputer 17 performs processing related to the present invention when the shift position notification device 5 is in the power-on state.
(1) Output voltage storing process corresponding to shift position (2) Shift position specifying process (3) Shift position notifying process is executed in parallel. Hereinafter, these processes will be sequentially described.

(1) Output Voltage Storage Process Corresponding to Shift Position When the controller 22 starts the output voltage storage process corresponding to the shift position, as shown in FIG. 13, whether or not the stored value stored flag is set. It is determined whether or not the stored value of the output voltage corresponding to each shift position (each shift position can be specified) is already stored in the nonvolatile memory 24 (step S11). If the controller 22 determines that the stored value of the output voltage corresponding to each shift position has already been stored in the nonvolatile memory 24 (step S11: YES), it determines whether or not the setting switch 19 has been pressed. Determination is made (step S12). If the controller 22 determines that the setting switch 19 has been pressed (step S12: YES), the controller 22 outputs a synthesis command to the speech synthesizer 25, and for example, causes the speaker 18 to utter a voice “Please park” (step S13). .

  On the other hand, if the controller 22 determines that the stored value of the output voltage corresponding to each shift position is not yet stored (not stored) in the non-volatile memory 24 (step S11: NO), the setting switch 19 is pressed. Without the above condition, a synthesis command is output to the voice synthesis unit 25, and for example, a voice “Please park” is uttered from the speaker 18 (step S13).

  Next, the controller 22 determines again whether or not the setting switch 19 has been pressed after uttering the voice “Please park” from the speaker 18 (step S14). If the setting switch 19 has been pressed, the controller 22 again. When the determination is made (step S14: YES), the measured value “V” of the output voltage of the distance measuring sensor 16 at that time is stored in the nonvolatile memory 24 as the stored value “Vp” of the output voltage at the parking position (first shift position). Store (step S15). That is, after confirming the voice “Please park” spoken from the speaker 18, if the shift lever 4 is not in the parking position, the user moves the shift lever 4 to the parking position, and the shift lever 4 is parked. If the position is the position, the shift lever 4 is maintained at the parking position and the setting switch 19 is pressed, whereby the storage value “Vp” of the output voltage at the parking position can be stored in the nonvolatile memory 24.

  Next, the controller 22 outputs a synthesis command to the voice synthesizer 25, and for example, causes the speaker 18 to utter a voice “Please reverse” (step S16). For example, the controller 22 determines again whether or not the setting switch 19 has been pressed after uttering a voice “Please reverse” from the speaker 18 (step S17), and determines again that the setting switch 19 has been pressed. (Step S17: YES), the measured value “V” of the output voltage of the distance measuring sensor 16 at that time is stored in the nonvolatile memory 24 as the stored value “Vr” of the output voltage at the reverse position (second shift position). (Step S18). That is, after confirming the voice “Please reverse” uttered from the speaker 18, the user moves the shift lever 4 from the parking position to the reverse position and presses the setting switch 19 to output the reverse position. The stored value “Vr” of the voltage can be stored in the nonvolatile memory 24.

Next, the controller 22 calculates a difference obtained by subtracting the storage value “Vr” of the reverse position output voltage from the storage value “Vp” of the parking position output voltage, and the calculated difference is a first predetermined value (specified value). It is determined whether or not (step S32). The first predetermined value is a stored value of a parking position and a stored value of a reverse position that can specify two shift positions (low position and second position in the present embodiment) farthest (separated) from the distance measuring sensor 16. And the minimum voltage difference. That is, if the difference obtained by subtracting the stored value “Vr” of the reverse position output voltage from the stored value “Vp” of the parking position output voltage is equal to or greater than the first predetermined value, all the shifts from the parking position to the low position are performed. The position can be specified sufficiently. On the other hand, if the difference is not greater than or equal to the first predetermined value (less than the first predetermined value), the parking position determination area and the reverse position determination area overlap, or some shift positions ( In particular, the shift position far from the distance measuring sensor 16) may not be specified.

  If the controller 22 determines that the calculated difference is greater than or equal to the first predetermined value (step S32: YES), for example, “make neutral”, “make drive”, “ “Please set second” and “Please set low” sounds from the speaker 18 in sequence, and each time it is determined that the setting switch 19 has been pressed, the measured value “V” of the output voltage of the distance measuring sensor 16 at that time As the storage value “Vn” of the output voltage at the neutral position, the storage value “Vd” of the output voltage at the drive position, the storage value “V2” of the output voltage at the second position, and the storage value “Vl” of the output voltage at the low position. The data is sequentially stored in the nonvolatile memory 24 (Steps S19 to S30).

  That is, the controller 22 determines that the difference obtained by subtracting the storage value “Vr” of the reverse position output voltage from the storage value “Vp” of the parking position output voltage is equal to or greater than the first predetermined value, as shown in FIG. If it is determined that the current mounting position of the shift position notification device 5 is appropriate, the stored values of the output voltages at the other shift positions are sequentially stored in the nonvolatile memory 24 while maintaining the current mounting position. Then, the controller 22 sets a stored value stored flag (step S31), and returns to step S11.

  On the other hand, the controller 22 determines that the difference obtained by subtracting the stored value “Vr” of the reverse position output voltage from the stored value “Vp” of the parking position output voltage is not equal to or greater than the first predetermined value (less than the first predetermined value). ) (Step S32: NO), it is determined whether the stored value “Vp” of the output voltage at the parking position is equal to or greater than a second predetermined value (step S33). The second predetermined value is a value for determining which position the stored value “Vp” of the output voltage at the parking position is relative to the peak of the output characteristic of the distance measuring sensor 16.

  When the controller 22 determines that the stored value “Vp” of the parking position output voltage is equal to or greater than the second predetermined value (step S33: YES), the stored value “Vp” of the parking position output voltage is It is determined that the output voltage of 16 is a region that increases as the distance to the shift lever 4 increases. Then, the controller 22 outputs a synthesis command to the voice synthesis unit 25, and for example, causes the speaker 18 to utter a voice (warning) that “the mounting position is too close to the shift lever. The user is prompted to correct the position of mounting 5 away from the shift lever 4 (step S34), and the process returns to step S11 described above. That is, the controller 22 indicates that the stored value “Vp” of the output voltage at the parking position is equal to or greater than the second predetermined value, and the current mounting position of the shift position notification device 5 is shifted as shown in FIGS. If it is determined that it is too close to the lever and is not appropriate, the stored value of the output voltage of the other shift position is not stored while the current mounting position is maintained, but the correction for moving the current mounting position away from the shift lever 4 is performed by the user. Prompt.

  On the other hand, when the controller 22 determines that the stored value “Vp” of the output voltage at the parking position is not equal to or higher than the second predetermined value (less than the second predetermined value) (step S33: NO), the output voltage at the parking position. Is determined to be an area in which the output voltage of the distance measuring sensor 16 asymptotically decreases as the distance to the shift lever 4 increases. Then, the controller 22 outputs a synthesis command to the voice synthesis unit 25, and for example, causes the speaker 18 to utter a voice (warning) that “the mounting position is too far from the shift lever. The user is prompted to correct the mounting position 5 closer to the shift lever 4 (step S35), and the process returns to step S11 described above. That is, the controller 22 indicates that the stored value “Vp” of the output voltage at the parking position is less than the second predetermined value, and the current mounting position of the shift position notification device 5 is far from the shift lever as shown in FIG. If it is determined that the current mounting position is not appropriate, the user is prompted to correct the current mounting position closer to the shift lever 4 instead of storing the stored value of the output voltage at another shift position while maintaining the current mounting position.

  In this embodiment, it is determined whether or not the difference obtained by subtracting the storage value “Vr” of the output voltage at the reverse position from the storage value “Vp” of the output voltage at the parking position is equal to or greater than the first predetermined value. Alternatively, it may be determined whether the difference between the stored values of any two shift positions is equal to or greater than a first predetermined value. In addition, the mode for prompting the user to correct the current mounting position is not limited to uttering a voice. For example, an LED may be provided, and the LED may be blinked or lit. In that case, a distinction is made between a correction that moves the current mounting position away from the shift lever 4 and a correction that moves the shift lever 4 closer to the shift lever 4, for example, the LED blinks or lights in green for the former, and the LED blinks red for the latter. Alternatively, it may be urged by lighting.

  In addition, when the stored values of the output voltages of all shift positions are sequentially stored, the stored value stored flag is set. However, for example, when the user does not press the setting switch 19, some shift positions are stored. If the stored value of the output voltage is stored, but the stored value of the output voltage at the remaining shift position is not stored, the stored value stored flag is not set. A stored value stored flag may be provided for each shift position.

(2) Shift position specifying process When the controller 22 starts the shift position specifying process, as shown in FIG. 14, the measured value “V” of the output voltage is output from the distance measuring sensor 16 to a predetermined sampling period (eg, 4 [milliseconds] ] Cycle) is determined (step S41). If the controller 22 determines that the measured value “V” of the output voltage has been input from the distance measuring sensor 16 (step S41: YES), the input measured value “V” of the output voltage and the output voltage at each shift position. Are compared with the determination areas based on the stored values “Vp”, “Vr”, “Vn”, “Vd”, “V2”, “Vl”, and the measured value “V” of the output voltage input from the distance measuring sensor 16. Is determined to be within the determination region of any shift position, the shift position corresponding to the determination region is specified (steps S42 to S53), and the process returns to step S41.

(3) Shift position notifying process As shown in FIG. 15, when starting the shift position notifying process, the controller 22 determines whether or not the shift lever 4 is in the parking position (step S61). If the controller 22 determines that the shift lever 4 is at the parking position (step S61: YES), the measured value “V” of the output voltage of the distance measuring sensor 16 changes from the parking position determination area to the determination area other than the parking position. It is determined whether or not the shift lever 4 has changed from the parking position (step S62). When the controller 22 determines that the shift lever 4 has changed from the parking position (step S62: YES), the controller 22 outputs a synthesis command to the voice synthesizer 25 and starts to utter the notification voice corresponding to the changed shift position ( Step S63). At this time, the controller 22 maintains the output level of the speaker 18 at a predetermined level (other than zero), thereby allowing the user to listen to the notification sound.

  Next, the controller 22 continues to determine whether or not the shift position of the shift lever 4 has changed after starting the utterance of the notification voice (step S64), and determines whether or not the utterance of the notification voice has ended. Determination is made (step S65). If the controller 22 determines that the shift position of the shift lever 4 has changed before determining that the utterance of the notification voice has ended (step S64: YES), the controller 22 interrupts the utterance of the notification voice during the utterance. Then (step S66), the process returns to the above-described step S63, and the utterance of the notification voice corresponding to the shift position after the change is started. On the other hand, if the controller 22 determines that the utterance of the notification voice has ended before determining that the shift position of the shift lever 4 has changed (step S65: YES), the controller 22 returns to step S61.

  More specifically, when the controller 22 determines that the shift lever 4 has been moved to the reverse position, for example, the controller 22 starts uttering a notification sound “reverse, lowering”, and the shift lever 4 is moved to the neutral position. For example, when the shift lever 4 is determined to have been moved to the drive position, for example, the utterance of the notification voice “drive, go forward” is started and the shift is started. When it is determined that the lever 4 has been moved to the second position, for example, the utterance of the notification sound “second, proceed forward” is started, and when it is determined that the shift lever 4 has been moved to the low position, for example, “low, proceed forward”. The utterance of the notification voice “Masu” is started. The voice uttered in the shift position notification process including the voice “reverse, descending backward” is a notification sound that can specify the shift position.

  In this case, for example, when the user sequentially moves the shift lever 4 from the parking position to the drive position via the reverse position and the neutral position, the shift lever 4 moves relatively quickly (this is a quick operation), and the speech If the operation of moving the shift lever 4 to the next shift position is performed before the utterance of the informing voice is terminated, the utterance of the informing voice is interrupted, for example, “reverse, backward”, “newt”, A notification voice that was interrupted in the middle of “drive, go ahead” is uttered. On the other hand, when the movement of the shift lever 4 is relatively slow (slow operation), and the operation of moving the shift lever 4 to the next shift position after the utterance of the informing voice is finished, The notification voice that can specify the next shift position is not uttered.

  When the controller 22 determines that the shift lever 4 has changed from the parking position to another shift position as described above, the controller 22 is not limited to uttering a notification sound for notifying the shift position after the change. When it is determined that is a parking position, for example, a notification voice “parking, parking” may be uttered. That is, when the shift lever 4 is in the parking position immediately after the user gets on or when the user moves the shift lever 4 to the parking position in order to get off, for example, “parking, parking”. Utters the notification voice. In addition, the user may be able to select a male voice, a female voice, a chime, a buzzer, etc. as the notification voice to be uttered.

  As described above, according to the first embodiment, the output voltage value corresponding to each shift position of the shift lever 4 is stored (learned) as a stored value in advance, and the output voltage is output from the distance measuring sensor 16. When the value is input as a measured value, the current shift position is specified using the stored value of each shift position stored. Then, if the difference obtained by subtracting the stored value “Vr” of the reverse position output voltage from the stored value “Vp” of the parking position output voltage is not equal to or greater than the first predetermined value, the current mounting position is informed. The warning is output. As a result, it is difficult to specify the shift position with the current mounting position, and it is possible to appropriately notify the user that the current mounting position is not appropriate.

  If the stored value “Vp” of the parking position output voltage is equal to or greater than the second predetermined value, the user is prompted to correct the current mounting position away from the shift lever 4, and the stored value “Vp” of the parking position output voltage is prompted. "Is not greater than or equal to the second predetermined value, the user is prompted to correct the current mounting position closer to the shift lever 4. Thereby, it is possible to appropriately notify the user how to correct the current mounting position.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS. In the first embodiment, the user simply tells the user whether to move away or approach the mounting position. In the second embodiment, the user informs the user how far away the mounting position is.

  That is, the non-volatile memory 24 stores the output characteristics of the distance measuring sensor 16 indicating the relationship between the distance to the detection target and the output voltage, as shown in FIG. As shown in FIG. 17, in the output voltage storing process corresponding to the shift position, the controller 22 subtracts the stored value “Vr” of the output voltage at the reverse position from the stored value “Vp” of the output voltage at the parking position. Is not greater than or equal to the first predetermined value (step S32: NO), and it is determined that the stored value “Vp” of the output voltage at the parking position is greater than or equal to the second predetermined value (step S33: YES), the parking position The difference between the distance corresponding to “Vp” and the distance corresponding to the peak position is calculated based on the stored value “Vp” of the output voltage and the output characteristics of the distance measuring sensor 16 stored in the nonvolatile memory 24. As shown in FIG. 18, the calculated difference is calculated as the recommended correction amount “ΔL_far” (step S71).

  Then, the controller 22 outputs a synthesis command to the voice synthesis unit 25, and for example, causes the speaker 18 to utter a voice “The mounting position is too close to the shift lever. Please keep away from“ ΔL_far ”” from the speaker 18. The user is prompted to make a correction to move the mounting position 5 away from the shift lever 4 by the recommended correction amount (step S72), and the process returns to the above-described step S11. In this case, since the stored value “Vp” of the output voltage at the current parking position has only to move to the opposite side of the peak, a value slightly larger than “ΔL_far” (with a margin) is uttered. May be.

  On the other hand, if the controller 22 determines that the stored value “Vp” of the output voltage at the parking position is not equal to or higher than the second predetermined value (step S33: NO), the stored value “Vp” of the output voltage at the parking position is non-volatile. Based on the output characteristics of the distance measuring sensor 16 stored in the memory 24, the difference between the distance corresponding to “Vp” and the distance corresponding to the peak position is calculated. As shown in FIG. The difference is calculated as a recommended correction amount “ΔL_near” (step S73).

  Then, the controller 22 outputs a synthesis command to the speech synthesizer 25, and for example, causes the speaker 18 to utter a voice “The mounting position is too far from the shift lever. Please approach by“ ΔL_near ””, and the shift position notification device The user is prompted to make a correction to bring the mounting position 5 closer to the recommended correction amount from the shift lever 4, and the process returns to step S11. In this case, since the stored value “Vp” of the output voltage at the current parking position does not have to move to the opposite side of the peak, a value slightly smaller than “ΔL_near” (with a margin) is spoken. You may let them. With such a configuration, it is possible not only to inform the user whether to move away or approach the mounting position, but also to notify the user how far the mounting position should be moved away or closer.

(Third embodiment)
Next, a third embodiment of the present invention will be described with reference to FIGS. Although the first embodiment is configured to calculate a difference obtained by subtracting the storage value “Vr” of the output voltage at the reverse position from the storage value “Vp” of the output voltage at the parking position, the third embodiment This is a configuration in which the determination of the magnitude of the stored value “Vp” of the output voltage at the position and the stored value “Vr” of the output voltage at the reverse position is added.

  As shown in FIG. 20, in the storage process of the output voltage corresponding to the shift position, the controller 22 stores the storage value “Vp” of the output voltage at the parking position in the nonvolatile memory 24 (step S15). The storage value “Vr” of the output voltage is stored in the nonvolatile memory 24 (step S18), and the storage value “Vn” of the output voltage at the neutral position is stored in the nonvolatile memory 24 (step S21). It is determined whether or not the stored value “Vr” of the output voltage is greater than or equal to the stored value “Vp” of the output voltage at the parking position (step S81).

  When the controller 22 determines that the stored value “Vr” of the output voltage at the reverse position is equal to or higher than the stored value “Vp” of the output voltage at the parking position (step S81: YES), the stored value “Vr” of the reverse position output voltage. The difference obtained by subtracting the stored value “Vp” of the output voltage at the parking position is calculated, and it is determined whether or not the calculated difference is equal to or greater than a third predetermined value (step S82). The third predetermined value is a value that establishes a condition that the determination area for the reverse position and the determination area for the parking position do not overlap.

  When the controller 22 determines that the difference obtained by subtracting the stored value “Vp” of the output voltage at the parking position from the stored value “Vr” of the output voltage at the reverse position is equal to or greater than the third predetermined value (step S82: YES), The difference obtained by subtracting the stored value “Vn” of the neutral position output voltage from the stored value “Vp” of the parking position output voltage is calculated, and it is determined whether or not the calculated difference is equal to or greater than a fourth predetermined value. (Step S83). The fourth predetermined value is a value that establishes a condition in which the parking position determination region and the neutral position determination region do not overlap.

  When the controller 22 determines that the difference obtained by subtracting the stored value “Vn” of the neutral position output voltage from the stored value “Vp” of the parking position output voltage is equal to or greater than the fourth predetermined value (step S83: YES), Thereafter, in the same manner, for example, “Please set the drive”, “Set it to the second”, and “Set it to the low” are sequentially uttered from the speaker 18, and each time it is determined that the setting switch 19 is pressed. The measured value “V” of the output voltage of the distance measuring sensor 16 at that time is stored as the stored value “Vd” of the output voltage at the drive position, the stored value “V2” of the output voltage at the second position, and the stored value of the output voltage at the low position. “Vl” is sequentially stored in the nonvolatile memory 24 (steps S22 to S30).

  On the other hand, when the controller 22 determines that the stored value “Vr” of the output voltage at the reverse position is not equal to or higher than the stored value “Vp” of the output voltage at the parking position (step S81: NO), the step described in the first embodiment is performed. S32 to S35 are performed. If the controller 22 determines that the difference obtained by subtracting the stored value “Vp” of the parking position output voltage from the stored value “Vr” of the output voltage of the reverse position is not equal to or greater than the third predetermined value (step S82: NO). If the difference obtained by subtracting the stored value “Vn” of the neutral position output voltage from the stored value “Vp” of the parking position output voltage is not equal to or greater than the fourth predetermined value (step S83: NO), Step S34 described in the embodiment is performed. In such a configuration, as shown in FIG. 21, when the stored value “Vp” of the output voltage at the parking position and the stored value “Vr” of the output voltage at the reverse position sandwich the peak of the output characteristics of the distance measuring sensor 16. Even so, if the above condition is satisfied, it can be determined that the current mounting position is appropriate.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described with reference to FIG. In addition, description is abbreviate | omitted about the same part as above-mentioned 1st Embodiment, and a different part is demonstrated. The first embodiment is configured to calculate the difference obtained by subtracting the stored value “Vr” of the output voltage at the reverse position from the stored value “Vp” of the output voltage at the parking position. The difference is calculated by subtracting the storage value of the output voltage at each shift position from the storage value of the output voltage at each shift position.

  As shown in FIG. 22, the controller 22 stores the stored values of the output voltages at all the shift positions in the nonvolatile memory 24 in the storage process of the output voltages corresponding to the shift positions (steps S <b> 11 to S <b> 30). For all shift positions, a difference is calculated by subtracting the storage value of the output voltage of each shift position from the storage value of the output voltage of each shift position, and all of the calculated differences are equal to or greater than the fifth predetermined value. It is determined whether or not (step S91). That is, the controller 22 stores, for example, the storage value “Vp” of the output voltage at the parking position, the storage value “Vr” of the output voltage at the reverse position, the stored value “Vn” of the output voltage at the neutral position, and the output voltage at the drive position. The difference of 15 combinations among the value “Vd”, the stored value “V2” of the output voltage at the second position, and the stored value “V1” of the output voltage at the low position is calculated, and all of the calculated differences are the fifth It is determined whether or not it is equal to or greater than a predetermined value. The fifth predetermined value is a minimum voltage difference that can specify all shift positions in consideration of noise, vibration, and the like.

  When the controller 22 determines that all of the 15 combinations are greater than or equal to the fifth predetermined value (step S91: YES), the controller 22 sets a stored value stored flag (step S31) and returns to step S11. On the other hand, when the controller 22 determines that any one of the 15 combinations is not equal to or greater than the fifth predetermined value (step S91: NO), the controller 22 outputs a synthesis command to the speech synthesizer 25 to correct the mounting position. A voice (warning) prompting the user is uttered from the speaker 18 to prompt the user to correct the mounting position of the shift position notification device 5 (step S92), and the process returns to the above-described step S11. In such a configuration, regardless of the output characteristics of the distance measuring sensor 16, if all the differences between the stored values of the respective shift positions are equal to or greater than the fifth predetermined value, the current mounting position Can be determined to be appropriate.

(Fifth embodiment)
Next, a fifth embodiment of the present invention will be described with reference to FIG. In addition, description is abbreviate | omitted about the same part as above-mentioned 1st Embodiment, and a different part is demonstrated. In the first embodiment, a value obtained by multiplying each stored value by a constant (constant) is calculated as a determination area for each shift position. In the fifth embodiment, an intermediate value of each stored value is used. Is a boundary between the determination areas of the respective shift positions.

  As shown in FIG. 23, the controller 22 sets (Vp + Vr) / 2 as the boundary between the parking position and the reverse position, and (Vr + Vn) / 2 as the boundary between the reverse position and the neutral position. Vn + Vd) / 2 is a boundary between the neutral position and the drive position, (Vd + V2) / 2 is a boundary between the drive position and the second position, and (V2 + Vl) / 2 is a distance between the second position and the low position. Set as the boundary of the judgment area.

In this case, the controller 22
V> (Vp + Vr) / 2
If it is determined that the shift lever 4 is in the parking position,
(Vp + Vr) / 2 ≧ V> (Vr + Vn) / 2
If it is determined that the shift lever 4 is in the reverse position,
(Vr + Vn) / 2 ≧ V> (Vn + Vd) / 2
If it is determined that the shift lever 4 is in the neutral position,
(Vn + Vd) / 2 ≧ V> (Vd + V2) / 2
If it is determined that the shift lever 4 is in the drive position,
(Vd + V2) / 2 ≧ V> (V2 + Vl) / 2
If it is determined that the shift lever 4 is in the second position,
(V2 + Vl) / 2 ≧ V
If it is determined that the shift lever 4 is in the low position, it is determined.
The controller 22 performs the shift position specifying process described in the first embodiment based on each shift position determination region set in this way.

(Sixth embodiment)
Next, a sixth embodiment of the present invention will be described with reference to FIG. In addition, description is abbreviate | omitted about the same part as above-mentioned 1st Embodiment, and a different part is demonstrated. The first embodiment is configured to set determination areas corresponding to all shift positions, but the fourth embodiment is configured to collectively determine determination areas corresponding to several shift positions. is there.

  As illustrated in FIG. 8 described in the first embodiment, the voltage range in which the shift position can be determined becomes narrower as the shift position moves to the drive position, the second position, and the low position. Therefore, in order to ensure a sufficient shift position determination region, the controller 22 moves to the second position or the low position as shown in FIG. 24 (the shift position where the vehicle behavior is the same). It is determined that That is, the controller 22 stores one stored value for the drive position, the second position, and the low position, and sets a determination area for the one stored value. By configuring in this way, the shift position can be specified while enhancing the resistance to disturbances such as noise and vibration (intensifying). In FIG. 24, the method of setting the intermediate value of each stored value as the boundary of the determination region has been described for the case where the drive position is determined when moving to the second position or the low position. Similarly, a method in which a value obtained by multiplying a constant (constant) is used as the determination region may be determined as the drive position when the position is moved to the second position or the low position.

(Other embodiments)

Some of the plurality of embodiments may be combined.
The distance measuring sensor is not limited to the configuration provided integrally with the shift position notification device, and the distance measurement sensor may be provided separately from the shift position notification device. With this configuration, the size of the shift position notification device can be reduced, and even if the space for mounting the shift position notification device is not secured near the shift lever, only the distance measurement sensor is mounted. If the space to be obtained is secured, the shift position of the shift lever can be appropriately notified by mounting the distance measuring sensor in the vicinity of the shift lever. In addition, the speaker may be provided separately from the shift position notification device, or the distance measurement sensor and the speaker may be provided separately from the shift position notification device.

  Further, the shift position notification device is not limited to the configuration in which the shift lever is mounted on the vehicle front side of the shift lever, and the shift position notification device may be mounted on the vehicle rear side of the shift lever. In this case, the difference obtained by sequentially storing the stored value “V1” of the output voltage at the low position and subtracting the stored value “V2” of the output voltage at the second position from the stored value “V1” of the output voltage at the low position is the first difference. By determining whether or not it is a predetermined value or more, it is determined whether or not the current mounting position is appropriate.

If so, a distance measuring sensor may be mounted near the shift lever. In addition, when applied to a shift lever arranged on the floor in the passenger compartment, the shift position notification device does not need to be mounted on the center console, as long as it can measure the distance to the shift lever. It may be attached to any part.

  The shift position notification device is not limited to the configuration in which the light emitting unit and the light receiving unit of the distance measuring sensor are on the extension line of the movement locus of the shift lever. For example, the light emitted from the light emitting unit of the distance measuring sensor may be reflected by the reflecting member and then reflected by the shift lever. In that case, it is possible to notify the user whether or not it is appropriate to include not only the mounting position of the distance measuring sensor but also the mounting position and reflection angle of the reflecting member or the like.

  A rotary encoder is used as the distance measuring means, and one end side of the cord (string) is fixed to the shift lever and the other end side is fixed to the encoder disk, and the encoder disk follows the change of the shift position of the shift lever. The shift position may be specified by utilizing the fact that the rotation angle changes.
