(engine starting control when unblock is processed)

First, engine starting control when processing with regard to unblock is illustrated, the microcomputer 20 of electric steering-lock device 1 Enter to exercise clamping screw 8 from latched position be moved to unlocked position unblock process when, using Hall element (SW-3) 19 Detect clamping screw 8 be located at half-way when, to engine starting control portion send " engine starting enabling signal ", from Unblock processes the unlocked position detection of the clamping screw 8 for starting not carry out being carried out by Hall element (SW-2) 18 in the stipulated time In the case of, " engine halt signal " is sent to engine starting control portion.Hereinafter, its specific control is illustrated based on Fig. 5 and Fig. 6 Step processed.

In the state of engine stop (not shown), as shown in figure 1, the clamping screw 8 of locking component 6 is located at the upper limit Latched position, its upper end are projected in recess 3a from the through hole 3d of shell 3 and are engaged with the slot 30a of steering spindle 30. In this condition, the rotation of steering spindle 30 is locked, in this locked condition, it is impossible to carry out rotation behaviour to steering wheel (not shown) Make, it is stolen thus, it is possible to prevent vehicle.Now, the Hall element (SW-1) 17 being configured in the latched position of printed circuit board 16 exists Detect located at the magnetic force of the magnet 11 of locking component 6 (arm 7A) when as shown in Figure 5 from disconnect (Not Lock (OFF)) switch to Connect (Lock (ON)), thus, microcomputer 20 recognizes clamping screw 8 and is moved to latched position.

When making operation is carried out to engine start switch (not shown) from above-mentioned state driver, the engine of body side Starting control portion detects the operation, carries out the unblock work of " unlocking request signal " is sent relative to electric steering-lock device 1 Deal with (the step of Fig. 6 S1).Then, the microcomputer 20 of electric steering-lock device 1 is relative to the unblock relay 26 shown in Fig. 4 Output " unlocking signal ".Then, unblock relay 26 switches to the position shown in dotted line, lock-up relay 25 to be located at solid line position Put, therefore, the path shown in solid of Fig. 4 is flow through from the electric current of battery 24 and start electro-motor 14, clamping screw 8 To unblock side shifting (step S2).

That is, when electro-motor 14 is activated as described above, the rotation of its output shaft 14a is subtracted by worm screw 15 and worm gear 12a Fast and direction is transferred to gear part 12 after being converted into right angle, and the gear part 12 rotates, therefore, it is formed with and is somebody's turn to do with carving to be located at The driver 7 of the external thread part 7a that the internal thread part 12b of 12 inner circumferential of gear part is screwed togather overcomes the active force of spring 13 and downward Motion.So, when driver 7 is moved downward, it is integrally formed in the arm 7A of the driver 7 and by pin 9 and 7 phase of driver The clamping screw 8 of link is moved downward.

Next, it is determined that whether detected from electro-motor 14 using Hall element (SW-3) to start to drive the stipulated time (such as 0.5 second) internal locking bolt 8 is moved to half-way (step S3).When clamping screw 8 is moved to half-way, configuration The magnet 11 located at locking component 6 (arm 7A) is detected in the Hall element (SW-3) 19 of the half-way of printed circuit board 16 Magnetic force, switches to connection (Middle (ON)) from disconnection (Not Middle (OFF)) as illustrated in fig. 5, and thus microcomputer 20 is recognized Half-way is moved to clamping screw 8.

And, when detecting that clamping screw 8 is moved to half-way at the appointed time, (judged result of step S3 is During "Yes"), the microcomputer 20 of electric steering-lock device 1 sends " engine starting enabling signal " to engine starting control portion, The engine starting control portion that have received " the engine starting enabling signal " starts the starting (step S4) of engine.Afterwards, Judge whether to detect that the driving from electro-motor 14 started in the stipulated time (such as 1.0 seconds) using Hall element (SW-2) 18 Clamping screw 8 is moved to unlocked position (step S5).When clamping screw 8 is moved to unlocked position, printed circuit board is configured at The Hall element (SW-2) 18 of 16 unlocked position detect located at the magnetic force of the magnet 11 of locking component 6 (arm 7A) when, such as Fig. 5 Shown to switch to connection (Unlock (ON)) from disconnection (Not Unlock (OFF)), thus microcomputer 20 recognizes clamping screw 8 and moves Move to unlocked position.

And, detect at the appointed time clamping screw 8 be shifted as shown in fig. 2 to during unlocked position (step S5 When judged result is "Yes"), as the inside of the through hole 3d of shell 3 is kept out of the way in the upper end of the clamping screw 8, therefore, lock The engaging of the slot 30a of tight bolt 8 and steering spindle 30 is released from, and the locking of steering spindle 30 is released from and becomes released state, The rotation process of driver's energy travel direction disk.

So, when judging that clamping screw 8 is moved to unlocked position by microcomputer 20, stop the driving of electro-motor 14 (step S6), and sent to the engine starting control portion of body side by communication I/F21 as shown in Figure 4 and order wire 22 " unblock completes signal ", normally terminates so as to the unblock of electric steering-lock device 1 is processed, and the start up process of engine is normal Ground terminates, and vehicle can be travelled (step S7), terminates a series of process (step S8).

On the other hand, start in the stipulated time, not detecting that clamping screw 8 is moved to solution in the driving from electro-motor 14 In the case of lock position (in the case that the judged result of step S5 is "No"), clamping screw 8 may not move to unlocked position, Therefore, the microcomputer 20 of electric steering-lock device 1 stops the driving (step S9) of electro-motor 14, to engine starting control portion Send " engine halt signal (unblock failure signal) ".Then, " engine halt signal (unsuccessfully believe by unblock to have received this Number) " engine starting control portion make engine stop (step S10), and make the start up process abnormal ending of engine, and make Vehicle can not be travelled (step S11), and the emergency warning lamp of instrument board (not shown) is flashed and, end abnormal to driver's notification A series of process (step S8).

In addition, do not detected using Hall element (SW-3) 19 send as an envoy to clamping screw 8 to unblock side shifting after regulation In the case that in time, the clamping screw 8 is moved to half-way (in the case that the result of determination of step S3 is "No"), also deposit In the possibility that the engaging of the slot 30a of clamping screw 8 and steering spindle 30 is not released from, therefore, electric steering-lock device 1 Microcomputer 20 stop electro-motor 14 driving (step S12), stop unblock process and abnormal ending (vehicle can not be travelled) (step Rapid S13), terminate a series of process (step S8).

As described above, in the present embodiment, entering to exercise clamping screw 8 and be moved to from latched position the solution of unlocked position When lock is processed, be not as conventional after clamping screw 8 is moved to unlocked position but wherein the way stage to engine Starting control portion sends " engine starting enabling signal " to carry out the start up process of engine, accordingly, it is capable to rapider than ever Carry out the starting of engine, the response started relative to the engine of driver can be improved.

And, do not carried out locking screw using Hall element (SW-2) 18 before the stipulated time being begun to pass through from unlocking motion In the case that the unlocked position of bolt 8 is detected, to the transmission of engine starting control portion, " engine halt signal (unsuccessfully believe by unblock Number) " and carry out the stopping process of engine, accordingly, it is capable to prevent not can confirm that clamping screw 8 in the state of unlocked position movement Engine work maintenance (engine continuous work), can ensure that higher security.

In addition, in the present embodiment, the half-way for starting the start up process of engine is set in clamping screw 8 and turns Boundary position i.e. " the engaging boundary position " being released to the engaging of the slot 30a of axle 30 and " unlocked position " between, therefore, In clamping screw 8 in the state of the half-way, in the engaging quilt of the clamping screw 8 and the slot 30a of steering spindle 30 The released state of releasing, therefore, even if just in case as some reason clamping screws 8 such as failure do not move to " unlocked position " In the case of continuing to engine work, the engaging with the slot 30a of steering spindle 30 of clamping screw 8 is also released from, can be really Protect the security started relative to engine.

(engine stop control during locking processing)

Then, illustrate engine stop control during locking processing based on Fig. 5 and Fig. 7 as follows.

In the state of under engine behavior, vehicle stops, as shown in Fig. 2 clamping screw 8 is located at the unblock of lower limit Position and the rotation of steering spindle 30 are not locked out, and can carry out rotation process to steering wheel (not shown) in this condition.

When operation is turned off to engine start switch (not shown) from above-mentioned state driver, engine starting control Portion carries out the stopping of engine and processes, and makes engine stop.And, engine starting control portion is carried out relative to electric steering Determine lock out action process (the step of Fig. 7 S1) that device 1 sends " locking request signal ".Then, electric steering-lock device 1 Microcomputer 20 exports " locking signal " relative to lock-up relay 25.Then, lock-up relay 25 as shown in Figure 4 switches to dotted line Shown position, unblock relay 26 are located at solid line position, therefore, the electric current from battery 24 is flow through shown in the dotted line of Fig. 4 Path and make electro-motor 14 invert start, clamping screw 8 to locking side shifting (step S2).

When the output shaft 14a of electro-motor 14 is inverted as described above, its rotation is delivered to via worm screw 15 and worm gear 12a Gear part 12, the gear part 12 are inverted, therefore, driver 7 is moved upwards, is integrally formed in the arm 7A of the driver 7 Moved with the clamping screw 8 being connected with driver 7 by pin 9 upwards.

It is determined whether being detected in stipulated time (such as 1.0 seconds) internal locking spiral shell using Hall element (SW-1) 17 Bolt 8 is moved to the situation (step S3) of latched position.

When clamping screw 8 is moved to latched position, the Hall element of the latched position of printed circuit board 16 is configured at (SW-1) 17 detect the magnetic force of the magnet 11 located at locking component 6 (arm 7A), as shown in figure 5, from disconnect (Not Lock (OFF) connection (Lock (ON))) is switched to, thus microcomputer 20 recognizes clamping screw 8 and is moved to latched position.
