Description

  The present invention relates to a shift device that switches a shift position of an automatic transmission.

  Conventionally, as a shift device for switching a shift position of an automatic transmission mounted on a vehicle, a shift device disposed on a floor console or the like (see, for example, “Patent Document 1”) and a steering column are disposed. Column shift devices (see, for example, “Patent Document 2”) are well known. In recent years, as shown in Patent Document 1, a so-called by-wire type shift device in which an automatic transmission and a shift device are mechanically separated has been proposed. In the shift device, the operation mode of the shift lever is detected as an electric signal, and the shift position (connection state) of the automatic transmission is electronically switched based on the detection signal, so that the mechanical mechanism such as a link mechanism is used. A simple configuration is not necessary. For this reason, since there is an advantage that the restriction of the arrangement position is eased and the miniaturization becomes easy, not only the floor shift device but also the column shift device by wire is being studied.

On the other hand, various anti-theft measures are taken for vehicles. For example, it has been conventionally proposed to mount an antitheft device as disclosed in Patent Document 3 on a vehicle. This anti-theft device collates the ID code stored in the electronic key (portable device) possessed by the user with the ID code stored in the vehicle, and unlocks the door lock when both ID codes match. A control device for permitting the engine to start is provided. The anti-theft device includes a lock member detachably provided on the steer connection nut shaft, an engagement position where the lock member is engaged with the steer connection nut shaft, and a non-engagement which does not engage the steer connection nut shaft. And a motor for displacement between the joint positions. Then, the control device, when the engine start stop switch is operated by the engine start permission state, with the locking member to drive control the motor so as to be displaced to the non-engaging position from the engaging position, the engine Start. When the engine is stopped by operating the engine start / stop switch, the control device drives and controls the motor so that the lock member is engaged with the steer connection nut shaft. When the lock member is engaged with the steer connection nut shaft, the rotation of the steer connection nut shaft is restricted. In this way, by combining the electronic theft countermeasure and the mechanical theft countermeasure, the vehicle can be suitably prevented from being stolen.

  However, although the above-described antitheft devices have been widely installed in vehicles, in recent years, organized or planned vehicle theft cases tend to increase year by year. For this reason, the further reinforcement | strengthening with respect to a vehicle antitheft measure is strongly desired. On the other hand, in recent years, there is still a tendency for vehicles to be electronic and multifunctional. The shift device is no exception, and a by-wire shift device as described above is being put into practical use as part of the computerization of vehicles. However, the function of the shift device is exclusively to change the shift position of the automatic transmission. For this reason, it has been desired to add some added value to the shift device from the viewpoint of multifunctionalization of the vehicle. In so-called luxury cars, there is a demand for such multi-functionality in particular. Accordingly, the applicant of the present application has conceived that the shift device is used to take some anti-theft measures in order to satisfy both the request for further strengthening of the vehicle anti-theft measures and the request for multifunctional shift devices. did. However, how to use the shift device to take measures against vehicle theft has not yet been realized.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a shift device that can secure a crime prevention performance against theft of a vehicle and can add added value.

According to a first aspect of the present invention, there is provided a shift lever that is operated when switching a shift position of an automatic transmission of a vehicle, a detection unit that detects an operation position of the shift lever and outputs a detection signal thereof, and the detection And a control means for generating a shift control signal for switching to a shift position corresponding to the operation position of the shift lever at that time based on the detection signal output from the means and outputting the shift control signal to the automatic transmission. In this shift device, the shift lever is provided so as to be detachable from an object to be arranged in the vehicle interior, and is driven by an electromotive force induced by an electromagnetic field received from the vehicle side when the shift lever is attached to the object to be arranged.

And a knob member provided so as to be rotatable about the axis of the lever body with respect to the opposite end of the lever body, and the detecting means detects a rotation operation position of the knob member with respect to the lever body. The detection signal is output to the control means, and the control means corresponds to the rotational operation position of the knob member at that time based on the detection signal output from the detection means. As its gist in that so as to output to the automatic transmission and generates a shift control signal for switching the shift position.

When getting off, the user removes the shift lever and carries it. This makes it difficult for a third party to perform a shifting operation, which is effective against theft of the vehicle. In addition, not only removing but also mounting the shift lever on the object to be installed during driving, the drive source of the vehicle or the shift position of the automatic transmission can be switched only after the ID collation between the shift lever and the vehicle is established. Allowed. For this reason, the further crime prevention performance with respect to vehicle theft is ensured. Further, by taking a theft prevention measure using the shift device, it is possible to give added value to the shift device that has been conventionally only switching the shift position of the automatic transmission.

For this reason, when getting off or getting on, the attaching and detaching work with respect to the arrangement object of the lever body is simplified. In addition, the shift position of the automatic transmission can be switched simply by rotating the knob member. For this reason, the shifting operation is simplified.

According to a second aspect of the present invention, there is provided a shift lever that is operated when switching a shift position of an automatic transmission of a vehicle, a detection unit that detects an operation position of the shift lever and outputs a detection signal thereof, and the detection And a control means for generating a shift control signal for switching to a shift position corresponding to the operation position of the shift lever at that time based on the detection signal output from the means and outputting the shift control signal to the automatic transmission. In this shift device, the shift lever includes a shift lever main body provided on the arrangement target, and a grip provided detachably on an end opposite to the arrangement target of the shift lever main body.

In addition, the grip is provided with a plurality of switches, and the switches are connected to the shift lever body. In the removed state, it functions as a locking and unlocking switch that is operated when the lock is manually operated remotely. On the other hand, when the grip is attached to the shift lever body, it is assigned in advance. The gist is that it functions as a shift selection switch for selecting the shift position of the automatic transmission .

When getting off, the user removes the grip and carries it. When driving, the grip is attached to the shift lever body, and driving of the vehicle drive source or switching of the shift position of the automatic transmission is permitted only after ID verification between the grip and the vehicle is established. For this reason, the further crime prevention performance with respect to vehicle theft is ensured. Further, by taking a theft prevention measure using the shift device, it is possible to give added value to the shift device that has been conventionally only switching the shift position of the automatic transmission.
In addition, since the grip has a function as an electronic key, the user does not need to carry the electronic key and the removed grip when the user gets off. For this reason, user convenience is improved.
Furthermore, the convenience of the user is further enhanced by further enhancing the functions of the electronic key in a state where the grip is detached from the shift lever body. Further, in a state where the grip is mounted on the shift lever body, it is possible to select the shift position of the automatic transmission pre-assigned to these switches by operating each switch. For this reason, the shift operation of the automatic transmission is simplified. Since the operation of the shift lever main body is not necessary, the shift lever main body can be fixed to the object to be arranged.

  ADVANTAGE OF THE INVENTION According to this invention, while ensuring the crime prevention performance with respect to theft of a vehicle, added value can be provided to a shift apparatus.

<First Embodiment>
A first embodiment in which the present invention is embodied in a by-wire column shift device that switches the shift position of an automatic transmission mounted on a vehicle will be described below with reference to FIGS.

  As shown in FIG. 1, a cylindrical steering column 11 that supports a steering connection nut shaft (not shown) on which a steering wheel 10 is mounted is supported in the vehicle interior. A rectangular opening 11 a extending in the circumferential direction with respect to the central axis O of the steering column 11 is formed on the side wall of the steering column 11. A shift device 12 is disposed inside the steering column 11 so as to correspond to the opening 11a.

  As shown in FIG. 2, the shift device 12 includes a connecting member 21 disposed inside the steering column 11 so as to correspond to the opening 11 a. The connecting member 21 is formed in a rectangular parallelepiped shape, and two shafts 22 a and 22 b extending in the direction along the central axis O are provided on side surfaces located on opposite sides in the direction along the central axis O of the steering column 11. Is provided. The shafts 22a and 22b are inserted and supported so as to be slidable and rotatable in insertion holes 23a and 24a of two bearing members 23 and 24 disposed inside the steering column 11. A cylindrical magnet 25 is fixed to the tip of one of the two shafts 22a and 22b (in this embodiment, the shaft 22a). In addition, a substrate 26 is disposed inside the steering column 11 so as to correspond to the magnet 25, and a magnetic sensor 27 is disposed on a side surface of the substrate 26 on the magnet 25 side so as to face the magnet 25. It is installed.

  Further, in the connecting member 21, a connecting hole 28 is formed on a side surface on the opening 11a side (a side surface where the opening 11a is desired from the inside). As shown in FIG. 3, a plurality of engagement recesses 28 a (only two are shown in FIG. 3) around the axis of the connection hole 28 are formed on the inner surface of the connection hole 28 of the connection member 21. It is formed at equal intervals. In the connection member 21, an antenna coil 29 is embedded on the opening side of the connection hole 28.

  The shift lever 30 is detachably connected to the connection hole 28. The shift lever 30 is formed in an L shape from the short shaft 30a and the long shaft 30b connected to one end thereof, and the end of the long shaft 30b opposite to the short shaft 30a is operated to the shift lever 30. A grip G that is sometimes gripped by the user is provided. The shift lever 30 is connected to the connecting member 21 by inserting the short shaft 30 a into the connecting hole 28. A transponder 31 is embedded at the distal end side of the short shaft 30a. The transponder 31 is disposed so as to correspond to the antenna coil 29 when the short shaft 30 a is inserted to a predetermined insertion depth with respect to the connection hole 28.

  In addition, a plurality of leaf springs 32 curved in an arc shape are arranged at equal intervals around the axis of the short shaft 30a on the outer peripheral surface on the distal end side of the short shaft 30a. When the leaf spring 32 receives an external force, both ends thereof are displaced to the opposite sides in the axial direction of the short shaft 30a against the elastic force of the leaf spring 32, so that the tip of the leaf spring 32 is at the short shaft 30a. It is provided so as to be displaced inward. When the short shaft 30a is inserted into the connecting hole 28, the leaf spring 32 resists its own elastic force by the tip of the leaf spring 32 being pressed against the inner peripheral surface of the connecting hole 28. And is displaced inward of the short axis 30a. When the short shaft 30a is inserted to a position where the leaf spring 32 corresponds to the engagement recess 28a of the connecting hole 28, the leaf spring 32 protrudes outward of the short shaft 30a by its own elastic force. Engage with. At this time, the transponder 31 embedded in the short shaft 30 a corresponds to the antenna coil 29 of the connecting member 21. When the leaf spring 32 is engaged with the engagement recess 28a, the rotation of the shift lever 30 can be performed by preventing the short shaft 30a, and thus the rotation of the shift lever 30 from being connected to the connecting hole 28, and the locking. .

  In the present embodiment, three operation positions are set: a reverse position “R” indicated by a solid line in FIG. 1, a neutral position “N” also indicated by a two-point difference line, and a drive position “D” also indicated by a two-point difference line. ing. The reverse position “R” is an operation position when the position is rotated upward from the neutral position “N” by a predetermined angle. The drive position “D” is an operation position when the rotary position is rotated downward from the neutral position “N” by a predetermined angle.

<Electrical configuration>
Next, the electrical configuration of the shift device 12 will be described.
As shown in FIG. 4, the shift device 12 includes an electronic control device 41. The electronic control device 41 is connected to a magnetic sensor 27, an antenna coil 29, an automatic transmission 42, and an engine 43.

  The electronic control device 41 detects whether or not the shift lever 30 is attached to the connecting member 21, more precisely, whether or not the short shaft 30a is inserted into the connecting hole 28 through a detection switch (not shown). When the electronic control device 41 detects the insertion of the short shaft 30a into the connecting hole 28 through the detection switch, the electronic control device 41 transmits a weak radio wave Sw (electromagnetic field) through the antenna coil 29. Here, the transponder 31 includes an antenna 31a (for example, a coil antenna), a control IC, and the like, and an identification code is stored in advance in the control IC. The transponder 31 is driven by the electromotive force induced in the antenna 31a by receiving the radio wave Sw (electromagnetic field) emitted from the vehicle side, that is, the antenna coil 29, and also stores the identification code stored in the control IC. An identification signal Sid is automatically transmitted. Upon receiving the identification signal Sid from the transponder 31, the electronic control unit 41 compares the identification code included in the identification signal Sid with the identification code recorded in advance on the condition that both identification codes match. Is permitted to start the engine 43, which is the drive source of the vehicle. Note that switching of the shift position of the automatic transmission 42 may be permitted.

  The magnetic sensor 27 includes a circuit in which four magnetoresistive elements (not shown) are connected in a bridge shape, a signal processing circuit of the circuit, and the like configured as a single IC chip. Each of the four magnetoresistive elements is made of a ferromagnetic material such as Ni—Co having an anisotropic magnetoresistive effect, and the resistance value is the direction of the magnetic flux applied to the magnetic sensor 27 (more precisely, the four magnetoresistive elements). It changes according to. The magnetic sensor 27 outputs the midpoint potential of the bridge circuit composed of four magnetoresistive elements as a magnetic flux detection signal Sm.

  Since the direction of the magnetic flux passing through the magnetic sensor 27 changes according to the rotational position of the magnet 25, that is, the operating angle (operating position) of the connecting member 21, and thus the shift lever 30, the detection signal output from the magnetic sensor 27. Sm also changes according to the operation angle of the shift lever 30. For this reason, the magnetic sensor 27 receives the magnetic flux from the magnet 25 in the direction corresponding to the operation angle of the shift lever 30 and outputs a detection signal Sm (voltage value) corresponding to the operation position of the shift lever 30. That is, the magnetic sensor 27 detects the operation position (operation angle or rotation angle) of the shift lever 30 as a change in the direction of magnetic flux accompanying the rotation of the shaft 22a on which the magnet 25 is provided, and outputs the detection signal Sm. The detection signal Sm from the magnetic sensor 27 is output to the electronic control device 41.

  Based on the detection signal Sm from the magnetic sensor 27, the electronic control unit 41 can determine the rotation angle of the shaft 22a and, in turn, the operation angle (rotation angle) of the shift lever 30. That is, the electronic control unit 41 determines the operation position of the shift lever 30 at that time based on the detection signal Sm output from the magnetic sensor 27, and shifts to switch to the shift position corresponding to the determined operation position. A control signal Sc is generated and output to the automatic transmission 42. Further, when a signal from a parking switch (not shown) is input, the electronic control unit 41 generates a shift control signal Sc for switching the shift position of the automatic transmission 42 to the parking position and outputs the shift control signal Sc to the automatic transmission 42. . The parking switch is provided, for example, on an instrument panel (not shown).

<Operation of the embodiment>
Next, a usage mode of the shift device configured as described above when starting operation and when getting off will be described.

  When starting the operation of the vehicle, the user first attaches the shift lever 30 possessed to the steering column 11. Specifically, the short shaft 30 a of the shift lever 30 is inserted into the connection hole 28 of the connection member 21. Then, the electronic control unit 41 detects this through an insertion detection switch (not shown), and transmits a weak radio wave Sw through the antenna coil 29 disposed on the connecting member 21. The transponder 31 disposed in the shift lever 30 is driven by the electromotive force induced in the antenna 31a upon receiving the radio wave Sw emitted from the antenna coil 29, and includes an identification signal including an identification code stored in the control IC. Send Sid automatically. Upon receiving the identification signal Sid from the transponder 31, the electronic control unit 41 compares the identification code included in the identification signal Sid with the identification code recorded in advance on the condition that both identification codes match. Is permitted to start the engine 43, which is the drive source of the vehicle. In this way, not only the shift lever 30 is mounted on the steering column 11 but also the start of the engine 43 is permitted only after the verification of the identification code is established between the shift lever 30 and the vehicle side. Security performance against theft is suitably secured.

<When getting off>
On the other hand, when getting off, the user first stops the engine by operating an engine start / stop switch (not shown) such as a push switch. Then, the user removes the shift lever 30 from the steering column 11 and gets off the vehicle while holding the removed shift lever 30. Since there is no shift lever 30 for switching the shift position of the automatic transmission 42 in the passenger compartment, it is difficult to switch the shift position. Therefore, crime prevention performance against vehicle theft is ensured.

  Further, the electronic control unit 41 detects that the short shaft 30a of the shift lever 30 has been removed from the connection hole 28 of the connection member 21 through an insertion detection switch (not shown), and starts the engine 43 that is the drive source of the vehicle. Not allowed. Therefore, when the shift lever 30 is detached from the steering column 11, the engine 43 is not started even when the engine start / stop switch is operated. In this way, measures against electronic theft against vehicle theft can be suitably secured for crime prevention performance.

  As described above, by using the shift device 12 that has conventionally only switched the shift position of the automatic transmission to ensure the crime prevention performance against theft of the vehicle, an added value is created in the shift device 12. In the recent trend toward multi-functionality of vehicles, such added value becomes a selling point, so there is a demand for such multi-functionality particularly in so-called luxury cars. According to the present embodiment, it is possible to meet such market demands.

<Modification>
Although not particularly mentioned in the present embodiment, the shift lever 30 may be held at each operation position, or may be neutral after the operation to the reverse position “R” or the drive position “D”. You may make it return to position "N" automatically. In the latter case, the electronic control unit 41 maintains the selected shift position (reverse position “R” or drive position “D”) as it is. That is, the electronic control unit 41 controls the shift position based on the operation position at the turning point with the neutral position “N” as the reference position.

  Further, in the present embodiment, the shift position can be changed and set as appropriate according to specifications and the like. For example, when the shift lever 30 is operated upward with a neutral position provided separately from the neutral position as a reference, the operation position is switched in the order of neutral position → neutral position “N” → reverse position “R”. When operated downward, the operation position is switched in the order of neutral position → neutral position “N” → drive position “D”. And when employ | adopting such a structure, it is preferable to set it as what is called a momentary structure which always returns to a neutral position automatically, when the operating force to the shift lever 30 is cancelled | released.

  Furthermore, in this embodiment, in addition to the magnetic sensor 27 using a magnetoresistive element as a means for detecting the operation position of the shift lever 30, a magnetic sensor using a mechanical sliding contact, a micro switch, and a Hall element, etc. Can also be used.

  In the present embodiment, the shift lever 30 is detachably connected to the connection hole 28 using the engagement relationship between the leaf spring 32 and the engagement recess 28a. It is also possible to do. That is, a claw (not shown) is formed on the outer peripheral surface of the shift lever 30 or the inner peripheral surface of the connecting hole 28, and a concave portion (not shown) that engages with the claw is formed on the inner peripheral surface of the connecting hole 28 or the outer peripheral surface of the shift lever 30. Form. Then, the shift lever 30 is fixed to the connecting member 21 by the engagement relationship between the claw and the recess.

<Effect of Embodiment>

A transponder 31 that automatically transmits radio waves is provided. The electronic control unit 41 receives a transmission radio wave emitted from the transponder 31 of the shift lever 30 attached to the steering column 11, and includes an identification code included in the transmission radio wave and an identification code stored in advance in itself. The engine 43 is permitted to start when the comparison is established.

  When the user gets off the vehicle, if the user removes the shift lever 30 from the steering column 11 and carries it, it is difficult for a third party to perform a shifting operation, which is effective against theft of the vehicle. In addition, the engine 43 is not only detachable, but the engine 43 is allowed to start only when the shift lever 30 is attached to the steering column 11 and the identification code between the shift lever 30 and the vehicle is verified. . For this reason, the further crime prevention performance with respect to vehicle theft is ensured. Further, by taking the anti-theft measures using the shift device 12, it is possible to give added value to the shift device 12 that has been conventionally only switching the shift position of the automatic transmission.

  (2) Due to the elastic engagement relationship between the plurality of leaf springs 32 provided on the outer peripheral surface on the distal end side of the short shaft 30a and the engaging recesses 28a provided on the inner peripheral surface of the connecting hole 28, the shift lever 30 Is connected to the connecting member 21 in a non-rotating and retaining state. For this reason, the attaching / detaching work of the shift lever 30 to the connecting member 21 is simplified.
