(engine starting when release is processed is controlled)
First, engine starting while processing about release is controlled and is described, the microcomputer 20 of electric steering-lock device 1 is when making lock bolt 8 move to the release processing of unlocked position from latched position, when utilizing Hall element (SW-3) 19 to detect lock bolt 8 to be positioned at half-way, to engine starting control part, send " engine starting enabling signal ", in the situation that carry out the unlocked position of the lock bolt 8 that undertaken by Hall element (SW-2) 18 in release process to start specified time, do not detect, to engine starting control part, send " engine halt signal ".Below, based on Fig. 5 and Fig. 6, the control step that it is concrete is described.
Under the state of not shown engine stop, as shown in Figure 1, the lock bolt 8 of locking component 6 is positioned at the latched position of the upper limit, and its upper end is projected in recess 3a and engages with the engagement groove 30a of steering shaft 30 from the through hole 3d of shell 3.Under this state, the rotation of steering shaft 30 is locked, under this lock-out state, can not be rotated operation to not shown bearing circle, can prevent that thus vehicle is stolen.Now, the Hall element (SW-1) 17 being disposed in the latched position of printed circuit board 16 switches to connection (Lock (ON)) from disconnecting (Not Lock (OFF)) as shown in Figure 5 when detecting the magnetic force of the magnet 11 of being located at locking component 6 (arm 7A), thus, microcomputer 20 recognizes lock bolt 8 and moves to latched position.
While not shown engine start switch being carried out to making operation from above-mentioned state driver, the engine starting control part of body side detects this operation, carries out sending with respect to electric steering-lock device 1 the release work disposal (the step S1 of Fig. 6) of " unlocking request signal ".So the microcomputer 20 of electric steering-lock device 1 is with respect to release relay 26 outputs " unlocking signal " shown in Fig. 4.So, release relay 26 switches to the position shown in dotted line, and locking relay 25 is positioned at solid line position, therefore, from the electric current of storage battery 24, flow through the path shown in the solid line of Fig. 4 and electro-motor 14 is started, lock bolt 8 is to release side shifting (step S2).
; when electro-motor 14 is activated as described above; the rotation of its output shaft 14a is slowed down by worm screw 15 and worm gear 12a and direction is passed to gear part 12 after being converted into right angle; these gear part 12 rotations; therefore the actuator 7 that, is formed with the external thread part 7a screwing togather with the internal thread part 12b that is located at 12 interior weeks of this gear part quarter overcomes the application force of spring 13 and moves downward.Like this, when actuator 7 moves downward, be integrally formed in the arm 7A of this actuator 7 and the lock bolt 8 that is connected by pin 9 and actuator 7 moves downward.
Then, judging whether to utilize Hall element (SW-3) to detect from electro-motor 14 starts to drive specified time (for example 0.5 second) internal locking bolt 8 to move to half-way (step S3).When lock bolt 8 moves to half-way, the Hall element (SW-3) 19 that is disposed at the half-way of printed circuit board 16 detects the magnetic force of the magnet 11 of being located at locking component 6 (arm 7A), from disconnecting (Not Middle (OFF)), switch to connection (Middle (ON)) as illustrated in fig. 5, microcomputer 20 recognizes lock bolt 8 and has moved to half-way thus.
And, when detecting at the appointed time lock bolt 8 and moving to half-way while judgment result is that "Yes" (step S3), the microcomputer 20 of electric steering-lock device 1 sends " engine starting enabling signal " to engine starting control part, and the engine starting control part that has received this " engine starting enabling signal " starts the starting (step S4) of driving engine.Afterwards, judge whether to utilize Hall element (SW-2) 18 to detect to start specified time (for example 1.0 seconds) internal locking bolt 8 from the driving of electro-motor 14 and move to unlocked position (step S5).When lock bolt 8 moves to unlocked position, when the Hall element (SW-2) 18 that is disposed at the unlocked position of printed circuit board 16 detects the magnetic force of the magnet 11 of being located at locking component 6 (arm 7A), from disconnecting (Not Unlock (OFF)), switch to connection (Unlock (ON)) as shown in Figure 5, microcomputer 20 recognizes lock bolt 8 and has moved to unlocked position thus.
And, when detecting at the appointed time lock bolt 8 and being shifted as shown in fig. 2 to unlocked position while judgment result is that "Yes" (step S5), the inside of keeping out of the way the through hole 3d of shell 3 due to the upper end of this lock bolt 8, therefore, the engaging of the engagement groove 30a of lock bolt 8 and steering shaft 30 is disengaged, the locking of steering shaft 30 is disengaged and becomes released state, the rotary manipulation that driver can travel direction dish.
Like this, when moving to unlocked position by microcomputer 20 judgement lock bolts 8, stop the driving (step S6) of electro-motor 14, and the communication I/F21 by as shown in Figure 4 and order wire 22 send " release settling signal " to the engine starting control part of body side, thereby the release of electric steering-lock device 1 is processed and is normally finished, the start up process of driving engine normally finishes, and vehicle can travel (step S7), finishes a series of processing (step S8).
On the other hand, in the situation that start not detect in specified time lock bolt 8 from the driving of electro-motor 14, move to unlocked position (step S5 judgment result is that "No"), lock bolt 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 part, sends " engine halt signal (release failure signal) ".So, the engine starting control part that has received this " engine halt signal (release failure signal) " makes engine stop (step S10), and make the start up process abnormal end of driving engine, and make vehicle can not travel (step S11), and make the warning light flicker of not shown instrument carrier panel and report extremely to driver, finishing a series of processing (step S8).
In addition, in the situation that utilize Hall element (SW-3) 19 not detect to send as an envoy to lock bolt 8 this lock bolt 8 move to half-way at the appointed time after release side shifting in the situation that (result of determination of step S3 is "No"), also the possibility that exists the engaging of the engagement groove 30a of lock bolt 8 and steering shaft 30 not to be disengaged, therefore, the microcomputer 20 of electric steering-lock device 1 stops the driving (step S12) of electro-motor 14, end release processing and abnormal end (vehicle can not travel) (step S13) finishes a series of processing (step S8).
As mentioned above, in the present embodiment, when making lock bolt 8 move to the release processing of unlocked position from latched position, not that after lock bolt 8 moves to unlocked position but therein the way stage sent to engine starting control part the start up process that " engine starting enabling signal " carries out driving engine as in the past, therefore, can, than more promptly carried out the starting of driving engine in the past, can improve the responsibility with respect to driver's engine starting.
And, in the situation that the unlocked position starting through not utilizing Hall element (SW-2) 18 to carry out lock bolt 8 before specified time from release action detects, to engine starting control part, send " engine halt signal (release failure signal) " and carry out the processing that stops of driving engine, therefore, maintain (the driving engine continuous firing) of the engine operation can not confirm under state that lock bolt 8 moves to unlocked position can be stoped, higher safety can be guaranteed.
In addition, in the present embodiment, it is between " engaging boundary position " and " unlocked position " with the boundary position being disengaged that engages of the engagement groove 30a of steering shaft 30 that the half-way of the start up process of beginning driving engine is set in lock bolt 8, therefore, under state at lock bolt 8 in half-way, engagement groove 30a in this lock bolt 8 and steering shaft 30 engages the released state being disengaged, therefore, even in the situation that contingency continues to maintain engine operation because some reason lock bolt 8 such as fault does not move to " unlocked position ", lock bolt 8 is disengaged with the engaging also of engagement groove 30a of steering shaft 30, can guarantee the safety with respect to engine starting.
(engine stop during locking processing is controlled)
Engine stop while then, as follows locking processing being described based on Fig. 5 and Fig. 7 is controlled.
Under engine behavior, under the state of vehicle stop, as shown in Figure 2, lock bolt 8 is positioned at the unlocked position of lower limit and the rotation of steering shaft 30 is not locked, under this state, can be rotated operation to not shown bearing circle.
While not shown engine start switch being carried out to opening operation from above-mentioned state driver, engine starting control part carries out the processing that stops of driving engine, makes engine stop.And engine starting control part carries out sending with respect to electric steering-lock device 1 the lock out action processing (the step S1 of Fig. 7) of " locking request signal ".So the microcomputer 20 of electric steering-lock device 1 is with respect to locking relay 25 outputs " locking signal ".So, locking relay 25 as shown in Figure 4 switches to the position shown in dotted line, and release relay 26 is positioned at solid line position, therefore, from the electric current of storage battery 24, flow through the path shown in the dotted line of Fig. 4 and electro-motor 14 reversions are started, lock bolt 8 is to locking side shifting (step S2).
When the output shaft 14a of electro-motor 14 reverses as described above, its rotation is delivered to gear part 12 via worm screw 15 and worm gear 12a, these gear part 12 reversions, therefore, actuator 7 upward movements, are integrally formed in the arm 7A of this actuator 7 and lock bolt 8 upward movements that are connected by pin 9 and actuator 7.
Then, determine whether and utilize Hall element (SW-1) 17 to detect at the appointed time the situation (step S3) that (for example 1.0 seconds) internal locking bolt 8 moves to latched position.
When lock bolt 8 moves to latched position, the Hall element (SW-1) 17 that is disposed at the latched position of printed circuit board 16 detects the magnetic force of the magnet 11 of being located at locking component 6 (arm 7A), as shown in Figure 5, from disconnecting (Not Lock (OFF)), switch to connection (Lock (ON)), microcomputer 20 recognizes lock bolt 8 and moves to latched position thus.
And, when detecting that lock bolt 8 moves to latched position as shown in Figure 1 at the appointed time while judgment result is that "Yes" (step S3), the upper end of lock bolt 8 is given prominence to and engages with the engagement groove 30a of steering shaft 30 from the recess 3a of shell 3, therefore, the blocked lock-out state of rotation that becomes steering shaft, in the time of preventing from stopping, vehicle is stolen.It should be noted that, in the situation that lock bolt 8 does not carry out well to the engaging of the engagement groove 30a of steering shaft 30, in the scope that lock bolt 8 relatively moves in pin 9 can the slotted hole 8a on being formed at this lock bolt 8, overcome the application force of spring 10 and move downward, therefore, can be to the excessive load of lock bolt 8 effect.
Like this, when microcomputer 20 is judged to be lock bolt 8 and moves to latched position, stop the driving (step S4) of electro-motor 14, and pass through the communication I/F21 shown in Fig. 4 and order wire 22 to the engine starting control part transmission " locking settling signal " of body side, thereby the locking processing of electric steering-lock device 1 normally finishes, vehicle can not travel (step SS), finishes a series of processing (step S6).
On the other hand, in the situation that lock bolt 8 does not move to latched position (situation that judgment result is that "No" of step S3) to detecting this lock bolt 8 in specified time after the movement of locking side starts, lock bolt 8 does not likely engage with the engagement groove 30a of steering shaft 30, therefore, the microcomputer 20 of electric steering-lock device 1 stops the driving of electro-motor 14 and makes locking processing end (step S7), and microcomputer 20 sends " locking failure signal " to engine starting control part.So the engine starting control part that has received this " locking failure signal " makes the warning light flicker of not shown instrument carrier panel and reports extremely to driver, finishes a series of processing (step S6).
It should be noted that, in the present embodiment, microcomputer 20 confirms whether from the driving of electro-motor 14, start specified time internal locking bolt 8 moves to half-way and unlocked position, but the counting of specified time is not limited to this zero hour, for example also can when confirming unlocked position, confirm that release screw bolt 8 moves to half-way and in specified time, whether moves to unlocked position afterwards, the counting of this specified time can at random be set the zero hour.
