Description

  The present invention relates to leisure vehicles (motorcycles, motorcycles, motor tricycles, three-wheel or four-wheel work vehicles, endless track work vehicles, and small planing boats (PWCs) where the driver's seat is open to the outside. The present invention relates to an antitheft device for the leisure vehicle suitable for use in a wide concept including the

A leisure vehicle, such as a motorcycle, has a configuration in which a driver's seat is open to the outside, and thus anyone can get in the driver's seat.
In addition, a mechanical key (refers to a key having a predetermined concavo-convex shape that enables mechanical unlocking to the tooth profile portion of the key and not having a function of transmitting a code code, etc.) A so-called “key switch” that inserts a “mechanical key” in the range into the keyhole and turns the main switch of the vehicle ON / OFF is generally exposed to the outside, such as in the vicinity of the driver's seat (for example, a meter panel in front of the driver's seat). It is arranged in the part.

Therefore, the anti-theft performance in the case of the motorcycle as compared with a four-wheeled vehicle such as a passenger car or a truck having a configuration in which the driver's seat is isolated from the outside of the vehicle and the user (driver) cannot enter the vehicle. Will be inferior.
In view of such a situation, the antitheft device mounted on the vehicle side matches the password data stored in the storage device on the vehicle side from the portable device (card type portable device) that is carried. Only when PIN data is received, the main switch on the vehicle side can be turned on by operating the mechanical key inserted into the key switch, and in this state, the theft configured to allow the vehicle engine to start A prevention device is provided.

  Further, in the case of a leisure vehicle such as a motorcycle, the driver's seat is open to the outside as described above. Therefore, the driver (rider) basically operates with gloves on.

  Therefore, when riding, the rider takes off the gloves, takes out the mechanical key from the pocket, etc., puts the mechanical key into the key hole of the key switch, rotates it to a predetermined position, etc., and then puts on the gloves again. The current situation is that we have to take simple steps.

In view of such a situation, the present applicant has also proposed a new electronic anti-theft system that eliminates the key switch that basically uses the mechanical key in order to eliminate the complicated procedure (Patent Document 1). reference). This electronic anti-theft system is used only when a portable device that transmits personal identification data and the personal identification data transmitted from the portable device are collated with the personal identification data stored in the memory of the main unit. It has an in-vehicle anti-theft device body that enables the use of the vehicle by turning on a predetermined electric circuit, and only the person who possesses the predetermined portable device can use the vehicle without using a mechanical key. It is configured to be able to. In the case of this electronic anti-theft device, a main switch is fixed to the vehicle instead of the key switch, and the main switch of the vehicle is turned on by rotating or pressing the main switch. It is configured to be able to be turned off.
Therefore, in the case of the electronic anti-theft device having such a configuration, it is not necessary to take out the mechanical key from the pocket etc. and insert it into the key hole every time the rider uses the vehicle, and therefore it is not necessary to take off or put on the glove. Excellent in terms.
Japanese Patent Application No. 2005-013581.

  However, even in a leisure vehicle equipped with an electronic anti-theft device as described above, when refueling, a mechanical key is taken out from a pocket or the like, and a locking device provided on a tank cap (also referred to as a fuel cap) Need to be unlocked. Similarly, when locking or unlocking a helmet holder or an accessory case, it is necessary to take out a mechanical key from a pocket or the like. Therefore, the rider must always carry the mechanical key in a pocket etc., but the main switch is not operated by the mechanical key, so there is a possibility that the mechanical key may be forgotten to be put in the pocket etc. Or when trying to unlock a helmet holder or the like, a situation arises for the first time that there is no mechanical key.

  The present invention has been made in view of such circumstances, and when riding, the vehicle can be used by turning the main switch on and off without taking off the gloves, and also when refueling, etc. An object of the present invention is to provide an anti-theft device that does not require carrying a mechanical key for unlocking a tank cap in a pocket or the like.

The object of the present invention is solved by an antitheft device for a leisure vehicle having the following configuration. That is, the anti-theft device for leisure vehicles according to the present invention has a portable device that is portable and transmits a predetermined password,
By rotating the mechanical key from the switch-on position to the switch-off position, the current supply to the power circuit of the leisure vehicle is disabled, and at the switch-off position, the mechanical key cannot be pulled out from the key hole. A cylinder lock configured to be able to pull out the mechanical key from the key hole at the pull-out position different from the switch-off position;
A rotation restricting locking member capable of restricting the rotation of the mechanical key;
An actuator for operating the rotation restricting locking member between a state of restricting the rotation of the mechanical key and an allowable state;
A receiving unit that receives the password code transmitted from the portable device, and when the received password code matches the password code stored in the memory, the actuator restricts the rotation restricting locking member. and a control device for controlling to operate to a state that allows the state to restrict the rotation of the mechanical key, possess,
In the cylinder lock, the pull-out position and the switch-off position are divided into one side and the other side of the rotation direction of the mechanical key across the switch-on position,
Further, the cylinder lock has a lock position, and is configured to lock the handle of the leisure vehicle by rotating the mechanical key to the lock position, and also in the lock position as well as the switch-off position. The mechanical key is not allowed to be pulled out .

According to the antitheft device for a leisure vehicle having such a configuration, only when a predetermined password is received from a portable device, the control device uses the actuator to connect the rotation restricting locking member to the mechanical key. controlled to operate to a state that allows the state to disable rotation. The pulling-out operation for pulling out the mechanical key from the key hole is regulated by a pulling-out regulating mechanism. The regulation by such pulling restricting mechanism may be regulated, such as the mechanical key only been disengaged state at a specific position in the mechanical structure of example the direction of rotation of the sheet cylinder lock is pulled out from the key hole, such case may be the regulation by utilizing the operation of the rotation restricting locking member according to prior Kia actuator. Then, by such a structure, be set to the state mechanical key is to always inserted in the locking device of the vehicle, if maintaining a predetermined portable device rider in a pocket or bag, etc., supply oil, etc. When necessary, the mechanical key can be extracted from the key hole.
Therefore, when starting the engine and running the vehicle, it is only necessary to wear the portable device. Also, when unlocking the tank cap locking device of the fuel tank, the portable device should be worn. For example, the mechanical key can be removed from the key hole to unlock the tank cap. Then, after closing the tank cap after refueling, the mechanical key removed from the tank cap may be returned to the original key hole of the locking device.
Incidentally, before Kia actuator, such as to perform both operations to the position for disabling the operation and possible position to position to enable the position to disable operation of the rotation restricting locking member It may be of a form (for example, an electric cylinder capable of reciprocating operation, an electric motor, etc.), and in such a case, a form of only one of these two actions (during forward movement and It may be an electric cylinder or an electric motor that can be driven only during one of the operations during the backward movement. Then, before the Kia actuator, when the actuator only possible forms operation of the one, the other operation may be a configuration as to operate by utilizing a spring or gravity.
In the case where the actuator is in a form in which only one operation is possible, each actuator may be configured to perform each operation by two actuators.

In anti-theft device of the said cylinder lock, when the front Symbol mechanical key is in the withdrawal position may be configured to leisure vehicle of the handle lock is disabled the current supply to be canceled and the power supply circuit .
Further, the cylinder lock, in order toward the one side in the rotational direction before Symbol mechanical key, the lock position, the switch-off position, may be arranged a switch-on position and a withdrawal position.

Further, the control device may be configured so that the rotation restricting locking member is configured to restrict the rotation of the mechanical key by the actuator if the password does not match. When a predetermined time elapses after the codes match, the actuator may be configured to operate the rotation restricting locking member from a state in which the rotation of the mechanical key is permitted to a state in which the rotation of the mechanical key is permitted.
The front Kikaido regulating locking member may be configured to permit rotation of the other positions when said mechanical key is in the switch-on position.
Furthermore, it has a press switch that outputs an ON signal while pressing the mechanical key downward, and the control device receives the ON signal from the press switch and transmits a request signal for a secret code to the portable device. It may be a configuration.

  According to the anti-theft device for leisure vehicles according to the present invention, the vehicle can be used by turning the lock bar of the vehicle on and off without taking off the gloves when getting on, and also when refueling, The mechanical key can be pulled out of the locking device to unlock the tank cap, etc., so if the rider carries only a portable device, the mechanical key must be carried in a pocket or the like while it is inserted into the keyhole of the vehicle. An anti-theft device can be obtained.

However, the former is preferable in terms of reduction in the number of parts, assembly man-hours, and the like and weight reduction.

Further, in this reference embodiment, the first restriction actuator 4A and the second restriction actuator 4B are both constituted by an electric cylinder capable of reciprocating, but may be constituted by an electric motor capable of reciprocating. Alternatively, it may be configured by an electric cylinder or an electric motor that can be driven only during either one of the forward movement and the backward movement. In the case of an actuator that can be driven only during the one operation, it is necessary to adopt a spring such as a return spring or to perform the one operation by gravity or the like.

As shown in FIG. 1, the locking device 1 further includes a cylinder 1G having a key hole 1B into which the mechanical key 1A is inserted, and the lock bar 1C described above.
The lock bar 1C is pressed (pressed downward in FIG. 1) by the cylinder 1G and locked at the lock position, and is urged to the anti-lock position side (lock release side 1: upward in FIG. 1). The spring 1r is configured to return from the locked position to the unlocked position. The cylinder 1G itself is also urged upward by a spring (not shown), and this cylinder 1G is attached to a known mechanical locking mechanism, for example, a cylinder 1G (see FIG. 1) shown in FIG. The position of “III” and the position of “II” shown in FIG. 2 are achieved by a locking mechanism including a locking protrusion 50 and a locking piece 51 formed on the cylinder case 52 that restricts the movement of the locking protrusion 50 to the side. Is configured to be rotatable from “III” to “II” or from “II” to “III” only when it is rotated while being pressed downward. It should be noted that between “I” and “II” shown in FIG.

  Further, as shown in FIGS. 1 to 5 and 7, a turning knob 1d that can be picked by a rider with a finger is formed on the top of the mechanical key 1A. The top of the mechanical key 1A has a reverse groove shape so that the top surface of the key hole 1B can be covered from above, and rain or the like is unlikely to enter the key hole 1B portion. It has a configuration. The knob 1d is sized so that the rider can easily pick it even when wearing a glove. Further, the top including the knob 1d of the mechanical key 1A is made of an impact-resistant material, for example, a metal such as steel, aluminum or titanium, or a resin having a high impact resistance such as ABS, in order to improve the anti-theft performance. Etc. Therefore, even when the top of the mechanical key 1A is hit with a hammer or the like, it is difficult to break.

The mechanical key 1A includes a tooth profile portion 1j having a predetermined uneven shape for enabling mechanical unlocking or mechanical locking. The tooth profile portion 1j of the mechanical key 1A is inserted into the cylinder 1G portion. Thus, the mechanical key is unlocked.
Further, as shown in FIG. 2 or FIGS. 3 to 5, the mechanical key 1 </ b> A includes a small-diameter portion 1 a formed in an upper portion and a locking hole 1 b formed in the small-diameter portion 1 a and extending in the lateral direction. To do. On both sides of the narrow diameter portion 1a in the vertical direction, portions 1p (see FIG. 5) and 1q having a larger diameter than the narrow diameter portion 1a are formed. In this reference embodiment, the diameter of the lower large-diameter portion 1q is slightly smaller than that of the upper large-diameter portion 1p of the small-diameter portion 1a.
The tip portion 2t of the first locking member 2A shown in FIG. 2 or FIG. 7 is positioned in the small diameter portion 1a, thereby restricting the upward pulling and the downward pressing operation of the mechanical key 1A. can do. Further, the first locking member 2A is inserted into the locking hole 1b, whereby the rotation operation (and the pulling-out operation) of the mechanical key 1A can be restricted. For this reason, the distal end portion 2t of the first locking member 2A is positioned at the small diameter portion 1a by the expansion and contraction operation of different stroke lengths of the first regulating actuator 4A provided on the base end side thereof. A first position a that is not inserted into the locking hole 1b, and a second position that further protrudes from the first position a and is inserted into the locking hole 1b so that the mechanical key 1A cannot be rotated. b and a third position c which is retracted from the small diameter portion 1a and can be rotated and pulled out by the mechanical key 1A can be selectively taken. Further, the first locking member 2A is composed of two members, a distal end portion 2t and a proximal end portion 2m, and the distal end portion 2t is connected to the proximal end portion 2m by a spring 2g as shown in FIG. It is energized forward and can be retracted. Further, in this reference form, the tip of the tip 2t is configured with a slope whose upper end retreats in the longitudinal direction with respect to the lower end, as shown in FIG. 7, and the lower end of the head of the mechanical key 1A. By chamfering 1n, when the tip 2t is at each of the first position a and the second position b, the lower end 1n comes into contact with the slope and the tip 2t is pressed by the spring 2g. By retreating, the mechanical key 1A can be inserted into the key hole 1B. 2 and 7, the state indicated by the solid line of the tip 2t of the locking member 2 indicates the position of the third position c, and the second position b and the first position a. Is indicated by a thin two-dot chain line.

Further, as shown in FIG. 1 or FIG. 8, the second locking member 2B is moved to the position of the lock bar 1C at the position where the lock bar 1C is locked by the expansion / contraction operation of the second restriction actuator 4B. In order to prevent the movement to the unlocking position (movement in the vertical direction) or the movement of the lock bar 1C to the locking position (movement in the vertical direction) when the lock bar 1C is in the unlocked state. In order to be able to prevent, it is provided to be able to project in the lateral direction so as to be locked to the locking groove 1Ua or the locking groove 1Ub formed on the side surface of the lock bar 1C from the side. The end of the second locking member 2B, in this reference embodiment, as shown in FIG. 8, with and intermediate height position and back by smaller dimensions as compared with the upper end in a more retracted bottom at the upper end It is composed of both slopes that protrude to the most distal end, and when the second locking member 2B is in the intermediate position (see the position indicated by the solid line in FIG. 8), the upper slope is the corner above the locking grooves 1Ua and 1Ub. When the mechanical key 1A is pressed downward when the lower slope is in contact with the portion and the lower slope is located at a position away from the lower corner of the locking grooves 1Ua and 1Ub, the lock bar 1C is locked from the unlocked position. It is configured to allow movement to a position and disable movement from a locked position to an unlocked position, that is, allow movement only downward. In FIG. 8, the second locking member 2B illustrated by a two-dot chain line so as to engage with the locking groove 1Ub is simply locked when the second locking member 2B is in the protruding state. It is shown to show the engaged state with respect to the groove 1Ub, and the vertical position of the second locking member 2B is located at the position indicated by the solid line and does not operate in the vertical direction.

The vertical dimension Lhb between the locking groove 1Ua and the locking groove 1Ub shown in FIG. 8 is equal to the upper end surface of the first locking member 2A and the lower surface of the top portion of the mechanical key 1A shown in FIG. Is substantially equal to the vertical dimension Lha up to the heel portion. Precisely, the dimension Lha is slightly larger than the dimension Lhb (in this reference embodiment, approximately 1 mm larger). For this reason, the mechanical key 1A is also depressed when the tip 2t of the first locking member 2A is located at the first position a and the tip of the second locking member 2B is located at the intermediate position z. By pressing, the lock bar 1C can be moved downward and locked via the cylinder 1G.

  The first regulating actuator 4A is connected to the control device 6 through a signal line L4, and the first position a, the second position b, and the third position described above according to a signal from the control device 6. It is configured to be able to take any position among the positions c. Further, the second regulating actuator 4B is connected to the control device 6 by a signal line L4, and the tip of the second locking member 2B is most retracted by a signal from the control device 6. It is configured to be able to take one of three positions (see FIG. 8): “retracted position y”, “projected position x” that protrudes most, and “intermediate position z” in the middle thereof. In the "retracted position y", the second locking member 2B is in a position where the second locking member 2B is retracted from the locking grooves 1Ua and 1Ub and cannot be locked. Therefore, in the "retracted position y", the lock bar 1C is not restrained in the vertical direction. Further, in the “intermediate position z”, the inclined surface facing upward of the both inclined surfaces of the second locking member 2B comes into contact with the upper corners of the locking grooves 1Ua and 1Ub, and below the lock bar 1C. Only move to is allowed. At the “projection position x”, the second locking member 2B is engaged with the locking grooves 1Ua and 1Ub, and the lock bar 1C is not allowed to move in any of the vertical directions.

The control device 6 includes an ECU (engine control unit) 3 forming a control device body, the handle lock circuit 8 connected to the ECU 3 via a signal line L8, and the ECU 3 via a signal line L9. It has a connected FI circuit (fuel injection circuit) 9 and an IG circuit (ignition circuit) 10 connected to the ECU 3 through a signal line L10. The ECU 3 includes a receiving unit 3R that receives a personal identification code transmitted wirelessly from the portable device 7, a transmission unit 3S that wirelessly transmits a personal identification code transmission request signal to the portable device 7, and the receiving unit 3R. And an antenna 3A connected to the transmitter 3S via a signal line. The ECU 3 also includes a main power control circuit 3C that controls the main power of the motorcycle on and off, and a memory 3M that stores a password code and the like. Further, the ECU 3 has a calculation unit 3F having a built-in CPU for collating a password and executing various controls. The calculation unit 3F includes the reception unit 3R, the transmission unit 3S, the main power control circuit 3C, The memory 3M is connected to each other by a control line L3.
In addition, the control device 6 including the ECU 3 is connected to an engine operation detection sensor 11 that detects the rotation state of the engine E (see FIG. 18) through a signal line L11.

  The engine operation detection sensor 11 is disposed on a crankshaft (not shown) portion of the engine E (see FIG. 18). However, the present invention is not limited to the crankshaft, and may be another part as long as the part rotates (operates) when the engine E such as a camshaft of the engine E is in an operating state.

The locking device 1 has a so-called key switch configuration in which a switch 12 that can be turned on and off by rotating the mechanical key 1A to a predetermined position is provided. That is, when the mechanical key 1A is rotated from the position "II" to the position "I" in FIG. 2, the switch 12 is turned on, and the ECU 3 causes the motorcycle B (FIG. 18) to turn on. The main power supply control circuit 3C (see FIG. 1) of the reference) can be turned on. Further, the mechanical key 1A is turned from the position “I” to the position “II” (or “III”) in FIG. 2, so that the switch 12 is turned off. The main power supply control circuit 3C of the motorcycle B (see FIG. 18) can be turned off.
Further, the locking device 1 is provided with a pressing switch 13 which is turned on only while pressing the mechanical key 1A downward by a small distance. When the mechanical key 1A is pressed downward at the position “II” or “III” in FIG. 2, the pressure switch 13 is turned ON, and this ON signal is sent to the control device 6 as a signal line. When the control device 6 receives the signal transmitted via L13, the calculation unit 3F of the ECU 3 of the control device 6 sends a password code request signal from the transmission unit 3S to the portable device 7 via the antenna 3A. Is configured to emit. In this reference embodiment, the switch 12 and the push switch 13 are configured as non-contact type so-called “proximity switches”. In the case of this reference embodiment, the pressing distance for turning on the pressing switch 13 is a clearance formed between the first locking member 2A and the locking hole 1b. (Gap) and a small extent corresponding to a gap (gap) formed between the second locking member 2B and the locking groove 1Ua (or locking 1Ub) when they are engaged with the locking groove 1Ua. It is comprised by the dimension (for example, about 0.3 mm-1 mm). Accordingly, the pressing switch 13 is in a state where the first locking member 2A is engaged with the locking hole 1b, and the tip of the second locking member 2B is the locking groove 1Ua of the lock bar 1C. Or in the state latched to latch 1Ub, it has the structure which can be pressed and can perform a switch function. The switch 12 and the pressing switch 13 are not limited to the “proximity switch”, but may be a contact type switch or other types of switches such as a pressure type and a mechanical type.

Further, after transmitting the code code request signal, the control device 6 enters a standby state for a confirmation signal from the portable device 7, and receives the confirmation signal including the code from the portable device 7, the control device 6. Has a program for performing the following processing based on this reception.
That is, the calculation unit 3F of the control device 6 calls a predetermined password stored in the memory 3M of the ECU 3, and collates the password with the password transmitted from the received portable device 7. Thus, it is configured to determine whether or not both of the password codes match.

Further, the handle lock circuit 8 includes a calculation unit 8F and a memory 8M that stores a password code, and the calculation unit 8F receives the password code transmitted from the portable device 7 from the ECU 3. The personal identification code and the personal identification code stored in the memory 8M are collated to determine whether or not they match.
Similarly, although not shown, the FI circuit 9 also has a calculation unit and a memory storing a password, and like the handle lock circuit 8, this calculation unit is transmitted from the portable device 7. When the password code is received from the ECU 3, the password code and the password code stored in the memory are collated to determine whether they match.

Further, the handle lock circuit 8, the FI circuit 9, the IG circuit 10, and the ECU 3 of the control device 6 are physically configured as separate units and are formed at different positions by being connected by signal lines. The control device 6 is configured to be formed. Therefore, even if a person who wants to steal the vehicle replaces only the unit of the ECU 3 of the control device 6 with an ECU that stores the same code as the code of the portable device he has, Since each password code stored in each memory of the handle lock circuit 8 and the FI circuit 9 does not match the password code of the portable device that the user has, the circuits cannot be operated. In other words, the person who is trying to steal stores all the units of the ECU 3, the handle lock circuit 8 and the FI circuit 9 in the memory with the same code as the portable device held by the person who is trying to steal. As long as the unit is not replaced, the anti-theft device of the vehicle cannot be released and stolen. In this reference embodiment, with this configuration, and further enhance the anti-theft function.

  Further, as described above, the portable device 7 is configured to wirelessly transmit a predetermined password stored in the portable device 7 when receiving the password request signal from the ECU 3 of the control device 6. ing.

By the way, in this reference form, as shown in FIG. 1, the portable device 7 stores a key 14 with a transponder in a part thereof, and the key 14 with a transponder is combined with the portable device 7. Therefore, it is configured so as to form the card shape. The tooth shape portion 14j of the key 14 with the transponder has the same uneven shape as the tooth shape portion 1j (see FIG. 3) of the mechanical key 1A, and is inserted into the key hole 1B of the locking device 1 to mechanically. It is configured so that it can be unlocked. In addition, a so-called “transponder” device is built in the head 14h of the key 14 with the transponder so that the same code as the code transmitted from the portable device 7 can be received only at a very short distance. You can make a call. Another form status, the "transponder" devices may be configured as being incorporated in the portable device away from the key.

  Further, as shown in FIG. 6, the arrangement position of the locking device 1 and the display device Di described above is the vicinity where the speedometer 18 and the tachometer 19 are arranged, that is, the motorcycle B (see FIG. 18). On the meter panel 17 provided at the center front of the handle Hn, the key hole 1B of the locking device 1 is exposed and the display portion of the display device Di is exposed. By arranging in this way, the operability of the mechanical key 1A and the like and the visibility of the display device Di are improved. However, it is not limited to such a position, and can be arranged at other positions of the vehicle such as a side portion of the vehicle.

By the way, in the case of this reference form, the first regulating actuator 4A and the second regulating actuator 4B described above are an electric motor as a drive source, and a rack and pinion mechanism that changes the rotation operation of the electric motor to a linear operation. It is comprised by the electric actuator provided with. However, it is not limited to this configuration, and it is needless to say that it may be configured by another form of actuator (for example, a solenoid or the like).

Thus, anti-theft device A motorcycle B according to the configured this preferred embodiment as described above, operates as follows. First, the case where the antitheft device A is unlocked, that is, the “unlocking control mode” will be described with reference to the flowchart shown in FIG.

  Now, the lock bar 1C of the locking device 1 is ON (the lower end is lowered to the position indicated by the two-dot chain line in FIG. 1) and the handle Hn (see FIG. 18) is locked (the mechanical key 1A is It is assumed that the motorcycle B is parked at the position “III” (see FIG. 2) and with the mechanical key 1A inserted in the key hole 1B. Further, it is assumed that a rider who is the owner of the motorcycle B holds the portable device 7 in a pocket or the like and intends to use the motorcycle B. As described above, even when the mechanical key 1A is parked while being inserted into the key hole 1B of the motorcycle B, the first locking member 2A is locked in the locking hole 1b of the mechanical key 1A. Since the first locking member 2A is in the second position b, a third party who does not carry the portable device 7 pulls out and rotates the mechanical key 1A from the key hole 1B. I can't do it. Therefore, the anti-theft function is achieved for a third party.

  Under such circumstances, the control device 6 determines whether or not the rider has pressed the mechanical key 1A inserted in the key hole 1B of the motorcycle B downward, that is, the pressing switch 13 is turned on. (Step 1: S1), and when the push switch 13 is turned on, upon receiving the ON signal, the calculation unit 3F of the ECU 3 sends a password code request signal via the transmission unit 3S and the antenna 3A. Wireless transmission is performed (step 2: S2).

  When the password code request signal is transmitted, the ECU 3 enters a waiting state for a confirmation signal having a password code from the portable device 7 (step 3: S3). On the other hand, the portable device 7 held in the rider's pocket or the like receives the password code request signal and transmits a predetermined password.

  When the confirmation signal is transmitted from the portable device 7 in this manner, this signal is transmitted to the calculation unit 3F via the antenna 3A and the reception unit 3R of the ECU 3, and the calculation unit 3F receives the received confirmation signal. It is verified whether or not the personal identification code matches the personal identification code stored in the memory 3M (step 4: S4). On the other hand, if there is no confirmation signal, it is checked whether or not the key 14 with transponder is present. If there is, the collation in step 4 is executed. If there is no key 14 with transponder, the series of this control is terminated.

  In the step 4, when both the collated passwords coincide with each other as a result of the collation by the calculation unit 3F of the ECU 3, the received confirmation signal is authenticated, and the first restriction actuator 4A, second The handle lock circuit 8 for driving the regulating actuator 4B is turned on, and the received password code is transmitted from the ECU 3 to the handle lock circuit 8 (step 5: S5). Note that, in the case of the above step 4, if they do not match, a series of this control is terminated.

  Next, the arithmetic unit 8F collates the received personal identification code with the personal identification code stored in the memory 8M in the handle lock circuit 8 (step 6: S6).

As a result of the collation, when the collated passwords coincide with each other, the handle lock circuit 8 operates the first regulating actuator 4A and the second regulating actuator 4B and the display device Di. The ECU 3 receives the signal from the handle lock circuit 8 and the arithmetic unit 3F of the ECU 3 activates a timer (step 7: S7). If the passwords do not match in step 6, this series of control is terminated.
As a specific operation of the first regulating actuator 4A and the second regulating actuator 4B, the distal end portion 2t of the first locking member 2A that is locked is moved from the second position b to the third position. In addition, the operation is performed such that the distal end portion of the second locking member 2B that is locked is positioned at the “retracted position y” that is separated from the lock bar 1C. Accordingly, the mechanical key 1A is released from the locked state by the first locking member 2A, and the lock bar 1C is released from the locking by the second locking member 2B. In this state, the mechanical key 1A can be pulled out from the key hole 1B, and the mechanical key 1A can be rotated from the “III” position to the “II” position while being pressed downward. Further, the mechanical key 1A can be extracted from the key hole 1B even in the state of being rotated to the position “II” as described above. The rotation and extraction are possible because the rider who has performed the unlocking action holds the predetermined portable device 7 (or the key 14 with the transponder), and therefore the portable device 7 or the transponder. A person who does not hold the attached key 14 cannot pull out or rotate the mechanical key 1A.
In addition, the display in the step 7 is an indication that the locking by the first and second locking members 2A and 2B has been released. Specifically, for example, the lamp is turned on three times at appropriate time intervals. Such a display may be used.

  The confirmation signal from the portable device 7 as described above is continuously transmitted at appropriate time intervals until the mechanical key 1A is rotated from “II” to “I” in step 8 described later. The above-described collation by the control device 6 can be continuously performed in accordance with the collation. Therefore, if the control device 6 does not receive the confirmation signal from the portable device 7 after the step 7 and before the mechanical key 1A rotates from “II” to “I” in step 8, The control device 6 transmits a signal to that effect to the handle lock circuit 8, and upon receiving this signal, the handle lock circuit 8 controls the first restricting actuator 4A and the first locking member 2A. 2t is moved from the third position c to the first position a. For this reason, a third party who does not hold the portable device 7 cannot pull out the mechanical key 1A. In this state, since the system relay described later is OFF, as a result, the anti-theft function is provided, and the mechanical key 1A is not stolen.

Further, the rotation from the position “III” to the position “II” is possible in this reference mode only when the rider rotates while pressing the mechanical key 1A and the mechanical restraint is released. It becomes. As a result, the handle Hn can be freely rotated.

  In this state, as long as the control circuit 6 continues to receive the confirmation signal from the portable device 7, the control circuit 6 is in a standby state until the mechanical key 1A is rotated to the position “I” in this state. It becomes. That is, the control device 6 is in a standby state in which it is checked whether or not the switch 12 is turned on (step 8: S8).

  When the mechanical key 1A is not rotated from the “II” position to the “I” position within a predetermined time, the ECU 3 determines whether or not the timer operated in step 7 has reached the predetermined time. Is checked (step 9: S9). In step 9, if the timer has not reached the predetermined time, the process returns to step 8;

When the rider turns the mechanical key 1A from the “II” position to the “I” position in the standby state in the step 8, the “verification” of the personal identification code is performed continuously as described above. And “matching authentication”, the main power supply control circuit 3C turns on the system relay. (Step 10: S10).
Thus, when the system relay is turned on, the IG circuit 10 is turned on and the FI circuit 9 is also turned on.

  Then, the FI circuit 9 which is turned on as described above receives the received password code from the ECU 3, and the arithmetic unit of the FI circuit 9 receives the received password code and the memory in the FI circuit 9. The password stored in the password is collated (step 11: S11).

  As a result of the collation, if the collated passwords match, the display device Di displays that effect, for example, turns on the display device Di continuously (step 12: S12). Viewing this display, the rider can visually recognize that the FI circuit 9 of the motorcycle B, that is, the fuel system is turned on. If the passwords do not match at the step 11, the series of control ends.

  Next, the calculation unit 3F of the ECU 3 checks whether or not the timer operated in step 7 has reached a predetermined time (step 13: S13).

  In step 13, when the time is within a predetermined time, the calculation unit 3F of the ECU 3 determines whether or not any one of the handle lock circuit 8, the FI circuit 9, and the IG circuit 10 is ON. This is confirmed by the signal (step 14: S14). In step 13, when a predetermined time has elapsed, a series of controls are terminated.

  When the reception of the signal indicating that the signal is ON from all the circuits is confirmed in step 14, the motorcycle B is in an engine startable state, that is, the motorcycle B is usable.

  In such a state, the control device 6 checks whether or not the mechanical key 1A has been rotated from the position “I” to the position “II” (step 15: S15).

  If the mechanical key 1A is not rotated from the position “I” to the position “II” in the step 15, whether or not the engine E is started by the starter button, a signal from the engine operation detection sensor 11 is detected. (Step 16: S16). That is, when the engine E rotation speed is the cranking rotation speed, it is determined that the engine E has been started. However, the start of the engine E can also be determined based on whether or not the starter circuit is energized. On the other hand, if the mechanical key 1A is rotated from the position “I” to the position “II” in step 15, the process proceeds to step 22.

  If the starter button of the motorcycle B is pressed in the step 16, whether or not the engine E is in operation is checked by a signal from the engine operation detection sensor 11 (step 17: S17). That is, when the engine E rotation speed is equal to or higher than the idling rotation speed, it is determined that the engine E is in an operating state. On the other hand, if the starter button of the motorcycle B is not pressed in step 16, the process returns to step 16.

  When the engine E is started in step 17, the ECU 3 of the control device 6 transmits a signal indicating that the engine E is in operation to the handle lock circuit 8 (step 18: S18).

  The handle lock circuit 8 that has received the signal operates the first regulating actuator 4A to move the tip 2t of the first locking member 2A to the first position a, and the second locking actuator 8A moves to the first position a. The control actuator 4B is operated so as to move the tip of the second locking member 2B to the “protrusion position x” (step 19: S19). As a result, the front end 2t of the first locking member 2A is locked to the small-diameter portion 1a to prevent the mechanical key 1A from being pulled upward, and the front end of the second locking member 2B is Locking in the locking groove 1Ub of the lock bar 1C prevents the lock bar 1C from protruding downward. Therefore, when the engine E is in operation, even if the rider mistakenly pulls out the mechanical key 1A, such a pulling operation can be prevented, and the lock bar 1C can be prevented from operating to the lock side. be able to.

  Further, even while the motorcycle B is running or the engine is running, the above-described verification and verification of the personal identification code from the portable device 7 and the personal identification code on the control device 6 side are continuously performed at appropriate time intervals. . Under such circumstances, the control device 6 checks whether or not a so-called “kill switch” provided in the motorcycle B is pressed (step 20: S20).

If the “kill switch” is not pressed in step 20, the control device 6 checks whether or not the mechanical key 1A is rotated from the position “I” to the position “II” (step 21). : S21). On the other hand, if the “kill switch” is pressed in step 20, the process proceeds to step 22.
If the mechanical key 1A is not rotated from the position “I” to the position “II” in step 21, the process returns to step 20.
Therefore, when the engine E of the motorcycle B is in an operating state (including a traveling state), the above-described control steps of Step 20 to Step 21 are repeated.

  On the other hand, when the mechanical key 1A is rotated from the position “I” to the position “II” in the step 15 and step 21, or when the “kill switch” is pressed in the step 20, the control is performed. The device 6 controls to turn off the FI circuit 9 and stop the supply of fuel to the engine E (step 22: S22). In this case, the engine E stops.

  Next, FIG. 10 shows the “locking control mode” when the engine E is stopped from the state in which the engine E of the motorcycle B is operating as described above and the anti-theft device A of the motorcycle B is turned on. This will be described with reference to the flowchart shown in the figure.

  In step 20, when the rider holding the portable device 7 presses the “kill switch” of the motorcycle B (when turned on), or in step 15 or step 21, the mechanical key 1A is When it is turned from the position “I” to the position “II”, the process proceeds to step 22 and the engine E of the motorcycle B is stopped. In this case, the “locking control mode” illustrated in FIG. The process proceeds to the control flowchart.

  In this “locking control mode”, within a predetermined time (for example, 5 to 10 minutes), the control device 6 is in a standby state until the mechanical key 1A is pressed and the pressing switch 13 is turned on. (Step 30: S30).

  Next, the control device 6 checks whether or not the predetermined time has passed (step 31: S31). And when predetermined time has not passed, it returns to the said step 30. FIG. On the other hand, when a predetermined time has elapsed, the routine proceeds to step 41 described later.

  In the standby state of the step 30, the mechanical key 1A, which is in a pressable state, is pressed by rotating from the position "I" to the position "II" or the position "III", so that the press switch When 13 is turned on, the calculation unit 3F of the ECU 3 receives the signal and wirelessly transmits a password request signal via the transmission unit 3S and the antenna 3A (step 32: S32).

  When the personal identification code request signal is transmitted, the control device 6 enters a standby state for a confirmation signal having a personal identification code from the portable device 7 (step 33: S33). On the other hand, the portable device 7 held in the rider's pocket or the like receives the password code request signal and transmits a predetermined password.

  When the confirmation signal including the password is transmitted from the portable device 7 in this way, the confirmation signal is transmitted to the calculation unit 3F via the antenna 3A and the reception unit 3R of the control device 6, and the calculation unit 3F Verifies whether or not the password code of the received confirmation signal matches the password code stored in the memory 3M (step 35: S35). On the other hand, if there is no confirmation signal, it is checked whether or not the key 14 with transponder is present (step 34: S34), and if there is, the collation in step 35 is executed. If there is no key 14 with a transponder, the process proceeds to step 41 described later.

In such a state, when the personal identification code of the confirmation signal having the personal identification code from the portable device 7 coincides with the personal identification code stored in the memory 3M, the ECU 3 sends a signal indicating that to the display device Di, for example, Then, blinking at a predetermined time interval is performed for 3 seconds (step 36: S36). If it is determined in step 35 that the password code does not match the password code stored in the memory 3M, the process proceeds to step 41.
Further, after the processing of step 36, a signal to that effect is transmitted to the handle lock circuit 8, and the main power supply control circuit 3C turns off the system relay (step 37: S37).

  Next, the handle lock circuit 8 that has received the signal operates the first restricting actuator 4A to position the distal end portion 2t of the first locking member 2A at the third position c, and The second regulating actuator 4B is actuated to position the tip of the second locking member 2B at the “intermediate position z” so that the lock bar 1C can be pressed, and the timer is activated (step 38: S38). As a result, the rider can pull out the mechanical key 1A from the key hole 1B, and can press the mechanical key 1A to project the lock bar 1C downward. In this state, when the rider presses the mechanical key 1A, the lock bar 1C is locked to the fixing member 20, and the lock bar 1C is locked by the second locking member 2B. That is, the handle lock is executed.

  Next, the handle lock circuit 8 checks whether or not the operated timer has reached a predetermined time (step 39: S39).

  When a predetermined time is reached by the timer, the handle lock circuit 8 operates the first restricting actuator 4A so that the tip 2t of the first locking member 2A is positioned at the first position a. (Step 40: S40). For this reason, the distal end portion 2t of the first locking member 2A is positioned at the small diameter portion 1a, and the mechanical key 1A thereafter cannot be pulled out.

  On the other hand, if the predetermined time has elapsed in step 31 or if the code does not match in step 34, the handle lock circuit 8 operates the first restricting actuator 4A to The front end 2t of the locking member 2A is operated so as to be positioned at the first position a, and the second regulating actuator 4B is operated (retracted) to move the front end of the second locking member 2B to the above-mentioned position. Position it at the intermediate position z (step 41: S41). For this reason, the distal end portion 2t of the first locking member 2A is positioned at the small diameter portion 1a, and the mechanical key 1A thereafter cannot be pulled out. When the mechanical key 1A is pressed to cause the lock bar 1C to protrude downward via the cylinder 1G, the lock bar 1C can be locked to the fixing member 20. That is, only the lock operation by the lock bar 1C is possible in the lock operation and the non-lock operation. Therefore, the rider or a third party can also perform the handle lock.

  From Step 31, Step 40, and Step 41, the routine proceeds to Step 42 where the power supply of the handle lock circuit 8 is turned off (Step 42: S42), and all the controls of the anti-theft device A are performed. Exit. In this state, when the mechanical key 1A is inserted into the key hole 1B, the mechanical key 1A cannot be removed. In this state, the lock bar 1C is moved downward by pressing the mechanical key 1A. The handle can be locked by pressing the button.

  By the way, when the battery of the portable device 7 runs out, the key 14 with a transponder accommodated in the portable device 7 is brought close to the ECU 3 (more precisely, the antenna 3A connected to the ECU 3). Thus, it is possible to perform the same function as when the portable device 7 is functioning. Further, by inserting the key 14 with the transponder into the key hole 1B, it is possible to perform the same function as when the portable device 7 and the mechanical key 1A are used. Therefore, even if the rider loses the mechanical key 1A extracted from the key hole 1B, if the key 14 with the transponder is inserted into the key hole 1B, all the anti-theft functions including the above-described anti-theft function are provided. It is possible to perform the same function as the mechanical key 1A.

(Working-shaped state)
Instead of the locking device 1 of the present anti-theft device A described in Reference shaped condition, the present invention can be real Hodokosuru with locking device 101 depicted in FIGS. 12 to 17. Locking device 101 according to this embodiment shaped state, as compared to the reference type state, required actuators in that it is possible to realize an antitheft device having the same functions in only one differs. Note that each structure of the locking device 101 of this embodiment shaped condition, the configuration same as or corresponding to the locking device 1 of Reference shaped condition, the reference numerals obtained by adding 100 to the reference numerals, the FIGS. 12 to 17 A duplicate description will be omitted.

In FIG. 12, reference numeral 101 is a locking device, 102 is a rotation regulating locking member that also functions as a locking operation regulating locking member and a pulling regulation locking member, and 103 is an ECU (engine control unit). , 104 is a rotation restricting actuator for operating the rotation restricting locking member 103, 106 is a control device, 107 is a portable device, 108 is a handle lock circuit, 109 is a FI circuit (fuel). injection circuit), 110 the IG circuit (ignition circuit), the 111 engine running detection sensor, 112 is a switch for ON-OFF of the main power supply control circuit of the motorcycle (the key switch type in this embodiment shaped state switch ), 113 is a press switch, 114 is a key with a transponder, and 115 is a mechanical key formed by a Hall IC or the like. Position in the rotational direction of 01A (rotational position) of the rotational position detecting sensor for detecting a.

In the case of a lock device 101 of this embodiment shaped condition, the mechanical key 101A is whether pulled out from the key hole 101B, as required by the general of the cylinder lock, is done by a mechanical (mechanical) configuration. Specifically, for example, as shown in FIG. 17, a pair of engagement pieces that can protrude and retract in the radial direction between a cylinder case 152 that rotatably accommodates a cylinder 101G and the cylinder 101G. (In this embodiment, pins) 101p1 and 101p2 are disposed, and the cylinder is only provided when the joint surface 101y of the pair of engagement pieces 101p1 and 101p2 is located at the boundary between the cylinder case 152 and the cylinder 101G. 101G is configured to be rotatable with respect to the cylinder case 152. In the case of a cylinder lock, when the mechanical key 101A is pulled out, the engagement pieces 101p1 and 101p2 of the cylinder case 152 move radially outward due to the movement of the concave / convex shape of the key in the pulling direction. space 152s to allow movement, certain positions of the mechanical key 101A is the direction of rotation, that is, only formed at a position of "IV" as Figure 13 of this embodiment shaped condition. Accordingly, only when the mechanical key 101A is located at this position (see the state of FIG. 17), the engagement piece 101p2 (see FIG. 17) allows the mechanical key 101A to be pulled out or inserted. That is, when the mechanical key 101A is located at a position other than “IV” in the rotational direction, that is, at positions “I” to “III”, the engagement pieces 101p1 and 102p2 have a space 152s (see FIG. 17)), the mechanical key 101A can be pulled out or inserted mechanically (mechanically) at positions "I" to "III". It is configured not to be possible due to restraint.
When the mechanical key 101A is inserted into the key hole 101B, the tooth shape portion 101j of the mechanical key 101A comes into contact with the engagement piece 101p2, and each distance corresponding to the protruding shape of the tooth shape of the tooth shape portion 101j is obtained. Engagement pieces 101p1 and 101p2 protrude in the outer diameter direction, and the joint surface 101y is positioned at the boundary between the cylinder case 152 and the cylinder 101G, and is configured to allow the mechanical key 101 to rotate.
Further, during the during the "I" and "II", and "III" and "IV" is adopted mechanical (mechanical) configuration shown in Figure 11 of reference shaped state, and pressed downward However, it can only be rotated.

Then, the lock device 101 according to this embodiment shaped condition, the mechanical key 101A is, as can be selectively positioned in any position of the four positions of the "I" - "IV", rotatable construction Has been. That is, the position “IV” is formed as a position dedicated to the drawing operation or insertion operation of the mechanical key 101A.
Further, as shown in FIG. 14, the rotation of the mechanical key 101A is impossible when the rotation regulating locking member 102 protrudes toward the mechanical key 101A and engages with the locking groove 101b of the mechanical key 101A. In addition, the rotation restricting locking member 102 is configured to be rotatable in a state where the rotation restricting locking member 102 is retracted and retracted from the locking groove 101b (disengaged state).
Whether the rotation is disabled or not is determined by the control device 106 controlling the operation of the actuator 104 that operates the rotation restricting locking member 102. Then, in this embodiment shaped condition, the "I", "II", the rotational operation tending to move from the "IV" to another position can be whether regulations, the turn restricting locking member This is performed under the control of the control device 106 via 102. Incidentally, the actuator 104 according to the present type state, as shown in FIG. 14, and is configured to be able to take two positions in the retracted position y and the projection position x.

  When the mechanical key 101A is turned from “II” to “I” by the rider's manual operation, the cylinder 101G of the locking device 101 rotates, and the lower end of the cylinder 101G shown in FIG. The eccentric shaft 101L, which is integrally attached in a state of being eccentric from the rotation center axis O1, is configured to push out the lock bar 101C and project (laterally project in FIG. 12).

Further, in the case of this locking device 101, the knob 101d of the mechanical key 101A is configured separately from the tooth profile portion 101j as shown in FIG. 15, and when a predetermined or higher rotational torque acts on the knob 101d, It is configured so as to rotate integrally with the tooth profile portion 101j when it idles and a predetermined or lower rotational torque acts. Specifically, as shown in FIG. 15 or FIG. 16, the corner (the chamfered corner: see FIG. 16) of the outer peripheral edge 101k integrated with the member on the tooth profile portion 101j side is the knob 101d. When engaged with the notch 101s (see FIG. 16) to transmit the rotational torque and a rotational torque of a predetermined level or more acts, the notch 101s is deformed to the enlarged diameter side and the outer peripheral edge 101k The corner slips with respect to the notch 101s and is idled. With this configuration, the tooth profile portion 101j is prevented from being damaged even when it is forcibly rotated. Incidentally, in the present type condition, and molding the outer peripheral portion 101k with that of another material having high wear resistance.

Further, when the lock device 101 according to this embodiment shaped condition, the mechanical key 101, any position of the four positions as shown in Matazu 13 as described above, from the "I" to "IV" Of these four positions, at the positions “I”, “II”, and “IV”, the pivot groove 101b illustrated in FIG. The restricting locking member 102 (see FIG. 14) is configured to be locked and prevent rotation. The locking groove 101b is formed in a direction orthogonal to the rotation direction corresponding to the positions of “I”, “II”, and “IV”.
At the position “I”, the eccentric mechanism (cam mechanism) causes the lock bar 101C of the locking device 101 to protrude as shown by the broken line in FIG. 12, and the handle Hn of the motorcycle B is locked to the handle lock. It is possible to form a closed state. Further, at the position “I”, the switch 112 is in an OFF position, that is, the relay of the main power circuit 103C of the motorcycle B is OFF (open). Therefore, at the position “I”, the motorcycle B cannot be pushed and moved to a predetermined position, and the engine E (see FIG. 18) cannot be started. That is, the anti-theft function is activated.
Further, at the position “II”, the lock bar 101C of the locking device 101 is in the retracted state (see the state shown by the solid line in FIG. 12), and the handle lock of the handle Hn of the motorcycle B is released. In addition, the position of the switch 112 is OFF (the relay of the main power supply circuit 103C is OFF (open)). Accordingly, since the handle Hn of the motorcycle is unlocked at the position “II”, the handle can be operated, and the motorcycle B can be pushed and moved to a desired position. However, since the switch 112 is in the OFF state, the engine E (see FIG. 18) cannot be started.
Further, at the position “III”, the lock bar 101C of the locking device 101 is in the retracted state (see the state indicated by the execution line in FIG. 12), and the handle lock of the handle Hn of the motorcycle B is released. In addition, the switch 112 is ON (the relay of the main power circuit 103C is ON (closed)). Accordingly, at the position of “III”, the handle Hn of the motorcycle is unlocked and the switch 112 is in an ON state. Therefore, if the passwords match in a series of password verifications. The engine E (see FIG. 18) of the motorcycle B can be started and run.
Further, at the position “IV”, the lock bar 101C of the locking device 101 is in a retracted state (see the state indicated by the execution line in FIG. 12), and the handle Hn of the motorcycle B is unlocked. In addition, the switch 112 is OFF (the relay of the main power supply circuit 103C is OFF (open)). At the position “IV”, the mechanical key 101A can be pulled out from the key hole 101B of the cylinder 101G as described above due to the above-described mechanical configuration shown in FIG. That is, at the position “IV”, the mechanical key 101A can be pulled out from the key hole 101B, or the mechanical key 101A can be inserted into the key hole 101B. Therefore, by pulling the mechanical key 101A at the position “IV” and extracting it, for example, the cap of the fuel tank and the key of the helmet holder at another position of the motorcycle B can be unlocked or locked.

Further, in the case of the locking device 101, when the mechanical key 101A is located at any of the positions “I” to “IV”, the pressing switch 113 is pressed by pressing the mechanical key 101A downward by a minute distance. operate, reference type on purpose also is configured to be able to transmit a request signal PIN code to the portable device 107.

And in the case of this locking device 101 configured in this way, it operates as follows. In other words,
In the parking state, if the mechanical key 101A is set to the position “I”, the handle is locked, and the control device 106 controls the actuator 104 to control the rotation restricting locking member 102. And the engaging groove 101b are engaged. For this reason, the mechanical key 101A cannot be rotated to a position other than “I”, and the switch 112 is OFF at the position “I”. It can be effectively prevented. Even if the mechanical key 101A is forcibly operated, only the knob 101d is idled and cannot be operated.

Then, the owner (rider) carrying the proper portable device 107 approaches the motorcycle B in which the mechanical key 101A is set at the position “I” in this way, and the mechanical switch 101A is pressed downward to press the push switch. 113 is pressed a reference type on purpose just as the authentication of a series of secret code (checking and determination of the matching) is executed. When the passwords are the same as a result of the password authentication, the control device 106 controls the actuator 104 to operate (retract) the rotation restricting locking member 102 to The engagement between the rotation regulating locking member 102 and the locking groove 101b is released. Accordingly, the rider can rotate the position from “I” to “II” while pressing the mechanical key 101A. By rotating the mechanical key 101A in this way, the lock bar 101C moves backward and the handle lock is released. In this state, the rider can push the motorcycle B by hand and move it to a desired location. Then, when a predetermined time (for example, several seconds) elapses at the position “II”, the control device 106 operates the actuator 104 to engage the rotation regulating locking member 102 with the locking groove 101b. The rotation of the mechanical key 101A is restrained. Accordingly, when a predetermined time has elapsed, the rotation cannot be made to a position other than “II”.

  In order to rotate the position “II” from the position “II” to the position “I” and the position “II” to the position “III” after the predetermined time, it is necessary to authenticate the password again. It becomes. Therefore, a person who does not hold the portable device 107 cannot perform the rotation operation from the position “II” to the position “I” or “III”, and an anti-theft function is generated.

  Next, when the rider holds the portable device 107 and rotates it from the position “II” to the position “III”, the mechanical code 101A is pressed downward to again authenticate the code. If the passwords are the same as a result of the authentication, the control device 106 controls the actuator 104 to operate (retract) the rotation restricting locking member 102. The engagement with the locking groove 101b is released. As a result, the mechanical key 101A can be rotated from the “II” position to the “III” position, and the switch 112 can be turned on by rotating in this way. Further, at the position of “III”, the lock bar 101C remains retracted and the handle lock is released. Therefore, when the rider starts the engine E (see FIG. 18) of the motorcycle B, the rider can use the motorcycle B.

  In addition, when the mechanical key 101A is pressed downward, the code is authenticated for the rotation from the position “III” to the position “IV” and the rotation from the position “III” to the position “II”. It can be rotated without any action. Therefore, when the rider wants to stop the engine, the engine E (see FIG. 18) can be quickly stopped.

Incidentally, in the case of this embodiment shaped state, as in the case of reference-type state, the motorcycle B during traveling, the rider through the "II" is a mechanical key 101A from position "III" to the position "I" When the control device 106 grasps that the engine E (see FIG. 18) is in an operating state by the engine operation detection sensor 111 even if it is going to rotate, the control device 106 operates the actuator 104 (to the release side). This prevents the steering wheel from being locked while the engine is running.

As described above, in this embodiment shaped state is, since the effective use of the mechanical properties of the cylinder lock, as compared with the case of Reference shaped condition, the locking member for the actuator and locking etc. Can be reduced. In addition, the actuator may be a simple actuator that operates only at the two positions of ON-OFF, and the control contents can be simplified because the number of objects to be controlled is reduced. When the number of objects to be controlled is reduced and the control contents are simplified, the number of steps of the control program can be reduced and the reliability can be improved.

  Further, in the case of the locking device 101, even if the mechanical key 101 is forcibly rotated by trying to steal the motorcycle B, for example, the mechanical key 101, that is, the tooth profile portion 101j thereof, is simply rotated. The cylinder 101G cannot be rotated. As a result, the tooth profile portion 101j is not damaged even under such circumstances.
