The microcomputer 52 executes a lock control process shown in FIG. In this locking control process, first, in step S1, it is determined whether or not the switch signal SH of the handle lock operation detection switch 15 is on. When the switch signal SH is on, the handle lock device 10 operates the lock key 14 It is determined that the operation has been performed in the locked state, and the process proceeds to step S2.
It is determined whether or not the previous switch signal SH is in the off state. If the previous switch signal SH is in the on state, it is determined that the locked state of the handle lock device 10 is continuing, and the process returns to the step S1 to return to step S1. If there is, it is determined that the operation has been performed from the unlocked state to the locked state, and the process proceeds to step S3.

In this step S3, it is determined whether or not the switch signal of the closed position detection switch 41 is in the off state. When the switch signal is in the on state, the locking rods 26 and 2 are determined.
7 is in the locked position and it is determined that the movement of the spoke 8 is restricted, and the process returns to the step S1 as it is.
If it is in the off state, it is determined that the locking rods 26 and 27 are open and in the unlocked state, and the process proceeds to step S4.

In step S4, the A / D converter 51
The battery voltage V _B input from the controller 2 is read, and then the process proceeds to step S5, where the read battery voltage V _B is
8 determines whether a sufficiently drivable set voltage V _BS above, when a V _B ≧ V _BS, it is determined that the battery voltage V _B is sufficient proceeds to step S6, described later After resetting the control state flag FS to “0”, the process proceeds to step S7.

In this step S7, a forward drive signal for driving the electric motor 28 to rotate clockwise, for example, is output, and then the process proceeds to step S8, where the switch signal SM of the intermediate position detection switch 42 is on. It is determined whether the locking rods 26 and 27 are locked when it is in the off state, and the process returns to step S7 when it is in the on state, and proceeds to step S9 when it is in the on state.

In step S9, it is determined whether or not the switch signal SC of the closed position detection switch 41 is on. When the switch signal SC is off, the locking rods 26 and 27 are moving from the intermediate position to the closed position. And the process moves to step S10. In this step S10, it is determined whether or not a predetermined time has elapsed since the intermediate position detection switch 42 was turned on, that is, whether or not the time sufficient for the locking rods 26 and 27 to move from the intermediate position to the closed position has elapsed. If the time has not elapsed, the process returns to the step S7, and if the predetermined time has elapsed, the locking rods 26 and 27
Is in contact with the spoke 8 and held at the intermediate position, and the process proceeds to step S11.

In step S11, the electric motor 36
Output of the forward rotation drive signal to the motor 3 is stopped.
6 is stopped, and then the process proceeds to step S12 to change the on state and the off state at a predetermined time period as shown in FIG. 7 (c) indicating that the locking rods 26 and 27 are stopped at the intermediate position. The buzzer drive signal and the light emitting diode drive signal are output to the buzzer 45 and the light emitting diode 44 to emit a warning sound and a warning light, and then the step S13 is performed.
Move to

In this step S13, it is determined whether or not the rider turns the rear wheel 6 on after turning the rear wheel 6 slightly so that both of the locking rods 26 and 27 do not face the spokes 8. When the switch is in the off state, the process returns to the step S12 to continue the generation of the alarm sound and the alarm light, and when the restart switch 43 is turned on, the process shifts to the step S7.

If the result of the determination in step S9 is that the closing position detection switch 41 is on, the locking rods 26 and 27 are inserted between the spokes 8 to the closed position for restricting the movement, that is, the locking position. When it is determined that the time has been reached, the process proceeds to step S14, the output of the motor drive signal is stopped, and then the process proceeds to step S15, where FIG.
The buzzer drive signal and the light emitting diode drive signal which are continuous twice with a relatively short ON state width as shown in FIG.
And output to the light emitting diode 44 before the step S
Return to 1.

The result of the determination in step S5 is V _B
If <V _BS , the process proceeds to step S16 to indicate that the battery voltage is insufficient. For example, as shown in FIG. After the light emitting diode (LED) drive signal is output to the buzzer 45 and the light emitting diode 44, the process returns to step S1.

On the other hand, the result of the determination in step S1 is based on the switch signal SH
Is in the off state, the process proceeds to step S17, and it is determined whether or not the previous switch signal SH is in the off state. When the switch signal SH is in the off state, it is assumed that the unlocking state of the handle lock device 10 is continued. The process returns to step S1, and if it is in the ON state, it is determined that the unlocking operation has been performed from the locked state of the handle lock device 10, and the process proceeds to step S18.

In this step S18, it is determined whether or not the switch signal SO of the open position detection switch 40 is on. When the switch signal SO is on, the locking rods 26 and 27 are in the open position, that is, in the unlock position. Then, the process returns to step S1 as it is, and when it is in the off state, it is determined that the locking rods 26 and 27 are in the closed position, that is, the locking position, and the process proceeds to step S19.

In step S19, the battery voltage V_B 
Is read, and then the process proceeds to step S20 where the battery voltage
V_BIs the set voltage V described above._BSDetermine whether or not
Then V _B≧ V_BS, The battery voltage V_BIs enough
And proceeds to step S21 to perform an unlocking operation.
The status flag FS indicating whether the
Is reset to “0” representing
Go and V_B<V_BSIf it is, go to step S22
I do.

In this step S22, the buzzer 45 and the light emitting diode 44 are
7D, the process proceeds to step S23, and the state flag F is output.
It is determined whether S is set to "1" or not, and if it is set to "1", a step S described later is performed.
The process jumps to step S32. If the flag has been reset to "0", the process proceeds to step S24, where the state flag FS is set to "1", and then proceeds to step S25.

In step S25, a drive signal for reverse rotation is output to the electric motor 36, and the process proceeds to step S26, where it is determined whether or not the switch signal SO of the open position detection switch 40 is on. If it is in the OFF state, it is determined that the locking rods 26 and 27 are being unlocked, and the flow shifts to step S27 to determine whether or not the switch signal SC of the closed position detection switch 41 is in the ON state. If it is, the process proceeds to step S28,
It is determined whether a predetermined time has elapsed since the electric motor 36 started reverse rotation. If the predetermined time has not elapsed, the process returns to step S27, and if the predetermined time has elapsed, the process proceeds to step S31.

If the result of the determination in step S27 is that the switch signal SC of the closed position detection switch 41 is in the OFF state, it is determined that the locking rods 26 and 27 have started moving, and the flow shifts to step S29 where the intermediate position is determined. It is determined whether or not the switch signal SM of the detection switch 42 is on, and when the switch signal SM is off, the locking rods 26 and 2 are turned off.
7 is determined to have moved beyond the intermediate position, and the flow returns to step S25. When the lock lever is in the ON state, the locking rods 26 and 27 are moving between the closed position and the intermediate position or are stopped. Then, the process proceeds to step S30.

In step S30, it is determined whether or not a sufficient predetermined time required for the locking rods 26 and 27 to move from the closed position to the intermediate position has elapsed. If the predetermined time has not elapsed, the process proceeds to step S25. When the predetermined time has elapsed, it is determined that the movement of the locking rods 26 and 27 has stopped, and the process proceeds to step S31. After the output of the reverse rotation drive signal of the electric motor 36 is stopped, the process proceeds to step S32. Then, an abnormality buzzer drive signal and a light emitting diode control signal that continue the ON state indicating the unlocking abnormality shown in FIG. 7E are output, and then the process proceeds to step S33, where the restart switch 43 is in the ON state. It is determined whether or not the electric motor is in the off state. If the state is in the off state, the process returns to step S32. 36 to resume the reverse rotation of the.

On the other hand, if the result of the determination in step S26 is that the switch signal SO of the open position detection switch 40 is ON, it is determined that the locking rods 26 and 27 have reached the open position, that is, the unlock position, and step S34 is determined. Then, after stopping the output of the motor reverse rotation drive signal, the process proceeds to step S3.
Then, as shown in FIG. 7 (a), the unlocking buzzer driving signal and the light emitting diode driving signal whose on-state width is relatively short are output to the buzzer 45 and the light emitting diode 44, and then the process returns to the step S1. .

In addition, in the microcomputer 52,
The voltage of the disconnection detection core wire 46c is monitored, and when this voltage becomes “0” or near it, it is determined that the theft has occurred, and the locking control process of FIG. While keeping the locked state, the buzzer 45 and the light emitting diode 44 output the continuous buzzer drive signal and the light emitting diode drive signal shown in FIG.

Next, the operation of the above embodiment will be described.
Now, the bicycle 1 is parked, and the handle lock device 1
0 lock key 14 is in the locked position and the stopper 13
Are engaged with the lock gear 12 so that the rotation of the front fork 4 is prohibited, and the distal ends of the curved rod portions 26c and 27c of the locking rods 26 and 27 of the rear wheel lock device 20 are as shown in FIG. Is inserted between the spokes 8 adjacent to the rear wheel 6 to prevent the spokes 8 from passing therethrough.

In this state, the processing of FIG. 6 has been executed, and since the handle lock device 10 is in the locked state, the switch signal SH of the handle lock operation detection switch 15 is output.
Is in the ON state, and the switch signal SH
Is in the ON state, steps S1 and S2 are repeated, the locking operation and the unlocking operation are not performed, and the locked state of the rear wheel lock device 20 is continued.

From this state, in order for the rider to run the bicycle 1, the cylinder lock 13 of the handle lock device 10 is used.
When the lock key 14 is inserted into the lock gear 11 and then turned to the unlock position, the stopper 12 is released from the lock gear 11 so that the handle 5 can be operated, and at the same time, the handle lock operation detection switch 15 is turned off. In the lock control process shown in FIG. 7, the process goes from step S1 to step S17. Since the previous state is the ON state, the process goes to step S18, where the rear wheel lock device 2
Since 0 is in the locked state, the switch signal SO of the open position detection switch 40 is in the off state, so that step S19
Migrated transition from crowded read the battery voltage V _B to step S20 to.

At this time, if the battery voltage V _B of the primary battery 22 is sufficiently high and is equal to or higher than the set voltage V _BS , the flow shifts to step S21 to reset the state flag FS to “0” and then shifts to step S25. Then, the electric motor 36 is driven to rotate in the reverse direction. At this time, when the spokes 8 are not in contact with the locking rods 26 and 27 and the locking rods 26 and 27 can move freely in the opening direction, the closing rods are first closed as the locking rods 26 and 27 move in the opening direction. When the switch signal SC of the position detection switch 41 is turned off, the switch signal SM of the intermediate position detection switch 42 is turned off, and then the open position detection switch SO is turned on, the process proceeds from step S26 to step S34. Then, the output of the motor reverse rotation drive signal is stopped, and
In step 35, the unlocking buzzer drive signal and the light emitting diode control signal are output to the buzzer 45 and the light emitting diode 44 to notify the unlocking state.

However, in the course of the releasing operation, one of the locking rods 26 and 27 is strongly pressed by the spoke 8 and
When the movement in the unlocking direction is restricted, the locking rods 26 and 27 remain between the closed position and the intermediate position, and after a predetermined time has elapsed, the output of the motor reverse drive signal is stopped, and the electric motor is stopped. 36 prevents the overload state from continuing, and outputs a buzzer drive signal and a light-emitting diode control signal indicating that the unlocking is abnormal to the buzzer 45 and the light-emitting diode 44, thereby notifying the rider of the unlocking abnormality. Then, the rider moves the rear wheel 6 slightly to release the pressure state of the locking rods 26 and 27 by the spokes 8 and then presses the re-operation switch 43, so that the process proceeds from step S33 to step S25, and the motor reversely rotates. A drive signal is output to the electric motor 36, and the locking rods 26 and 27 are unlocked.

As described above, since the rear wheel lock device 20 is automatically unlocked in response to the unlocking operation of the handle lock device 10, even if there are two lock devices on the front wheel side and the rear wheel side, the rider is not required. However, it is possible to eliminate the trouble of unlocking each of them, and it is possible to exert a reliable anti-theft effect while reliably preventing the user from feeling annoying. When the bicycle is stopped and the bicycle is parked after running the bicycle in this unlocked state, the lock key 14 inserted in the handle lock device 10 is turned to the locking position in the opposite manner. When the handle 5 is removed, the stopper 12 engages with the lock gear 11 and the rotation of the handle 5 is locked. At the same time, the switch signal SH of the steering wheel lock operation detection switch 15 is turned on, so in the locking control process of FIG. 7, the process proceeds from step S1 to step S2, and since the previous switch signal SH was in the off state, proceeds to S3, the switch signal SC in the closed position detection switch 41 is in oFF state, the process proceeds to step S4, in the same manner as when unlocking described above, the battery voltage V _B of the primary battery 22 is set voltage V _BS or Is satisfied, step S7 to step S7
9 drives the electric motor 28 in the forward direction, thereby moving the nut 33 upward.
And 27 are rotated counterclockwise and clockwise, respectively.
When the tips of the locking rods 26 and 27 face between the spokes 8 adjacent to the rear wheel 6, the locking state is returned to the locked state shown in FIG. A buzzer sound is emitted, and the same blinking is performed by the light emitting diode 44.

At this time, when one of the ends of the locking rods 26 and 27 comes into contact with the spoke 8, the rotation of the locking rods 26 and 27 is stopped at that position, and this state has elapsed for a predetermined time or more. Sometimes, from step S10 to step S1
In step 1, the output of the forward rotation drive signal of the electric motor 36 is stopped, the overload state of the electric motor 36 is eliminated, and the electric motor 36 stops at the intermediate position where the locking rods 26 and 27 abut the spokes 8. 7C, an alarm sound and an alarm light that repeat an ON state and an OFF state at a predetermined cycle in FIG. 7C are emitted from the buzzer 45 and the light emitting diode 44 to notify the rider.

For this reason, the rider turns the rear wheel 6 slightly so that the contact between the locking rods 26 and 27 and the spokes 8 is released, and the re-operation switch 43 is turned on. The movement of the locking rods 26 and 27 to the closed position, that is, the locked position, is resumed. When the locking rods 26 and 27 reach the closed position, that is, the locked position, the switch signal SC of the closed position detection switch 41 is turned on, and the forward rotation drive signal 7 is stopped, and a warning sound and a warning light shown in FIG. 7B indicating the locked state are output from the buzzer 45 and the light emitting diode 44 to notify the rider.

As described above, the rear wheel locking device 20 having the above-described configuration allows the locking rod 26 to be attached to the spoke 8 of the rear wheel 6 during locking.
When the locking rods 26 and 27 stop at the intermediate position due to the contact between the spokes 8 and 27, the electric motor 36 rotates the screw shaft 32 via the worm gear as a reduction gear. The spokes 8 are bent by any of the locking rods 26 and 27 that are in use.
