Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a starting control device for a vehicle which permits starting of an engine in response to an operation on an operating means.

[0002]

2. Description of the Related Art In recent years, it has been desired to improve the safety of a vehicle, and in particular, various types have been proposed to prevent an illegal operation of an ignition switch.

As an example of such a configuration, for example, an ID code is stored in an IC card and I
The ID code of the IC card is read by the C-card reader, and when the read ID code matches the preset registration code, the operation of the switch is validated and the engine start is permitted.

In this case, since the ID code stored in the IC card is excellent in confidentiality, the security can be enhanced as compared with the configuration in which the ignition switch is operated by the ignition key.

[0005]

However, in the conventional ignition switch, the LOC which is the traveling prohibition position is set.
When the steering wheel is operated to the K position, the rotation of the steering shaft is mechanically prohibited and the travel permission position (for example, AC
Since the steering shaft rotation prohibition state is released when the steering shaft is operated to the C position, the ON position), when the ID code stored in the IC card matches the registration code, the switch is operated according to the operation. However, there is a problem in that it cannot be used as a substitute for the ignition switch that also functions as the steering lock means by simply configuring the engine to permit the engine to start.

Further, since the operation feeling to the switch is constant regardless of whether the operation to the switch is valid or not, the operation to the switch is valid because the reading of the ID code from the IC card is uncertain, for example. Otherwise, the user will not be able to start the engine regardless of the operation on the switch, which is disadvantageous in terms of usability.

The present invention has been made in view of the above circumstances, and an object of the invention is to start an engine in response to an operation when a legitimate electronic code is input.
It is an object of the present invention to provide a vehicle start control device capable of prohibiting and permitting rotation of a steering shaft as well as improving usability.

[0008]

A vehicle start control device of the present invention is provided with operating means operable at a travel prohibiting position and a travel permitting position including an engine starting position, and an electronic code provided from the outside is provided. An identification means is provided for instructing to permit the operation of the operation means when the registration code is set in advance, and an operation permission means provided corresponding to the operation means is provided, and the operation means and the operation are provided. In addition to connecting the permission means with a predetermined connection force, a connection control means is provided for releasing the connection state when the operation means is operated with a force greater than the connection force while the movement of the operation permission means is prohibited, In addition, a drive means is provided which is driven so as to prohibit the movement of the operation permitting means and release the movement prohibited state for the operation permitting means in response to a command from the identifying means. , A connection release state detection for detecting that the connection control means is in a connection release state by providing an operation position detection means for outputting a signal indicating each state in which the operation means is operated to the travel prohibited position and the travel permitted position Steering lock for prohibiting the rotation of the steering shaft when the operating means is operated to the traveling prohibited position by providing a means for outputting a notification signal to the outside according to the detection state by the disconnection state detecting means. Means are provided (Claim 1).

[0014]

In the vehicle start control device according to the first aspect of the present invention, the drive means normally prohibits the movement of the operation permitting means. Therefore, it is impossible to start the engine by operating the operating means connected to the operation permitting means by the connection control means with a predetermined connecting force from the travel prohibiting position to the travel permitting position.

To start the engine, the identification means is given a predetermined electronic code. Then, the identification means outputs a command when the given electronic code matches the preset registration code. Then, the drive means is driven in response to the command from the identification means to release the movement prohibited state for the operation permission means. As a result, the operating means can be operated, so that the operating position detecting means outputs an operating signal indicating the operating position of the operating means in response to the operation of the operating means. Therefore, the engine can be started based on the operation signal from the operation position detecting means.

On the other hand, the steering lock means prohibits the rotation of the steering shaft when the operation means is operated to the traveling prohibition position. Then, when the operating means is operated from the travel-prohibited position to the travel-permitted position as described above,
Since the steering lock means releases the rotation prohibition state of the steering shaft, the steering operation can be performed and the vehicle can travel.

When the operating means is operated to the traveling prohibited position after the vehicle is stopped, the drive means inhibits the operation of the operating means and the steering lock means inhibits the rotation of the steering shaft.

By the way, although the operation of the operating means is prohibited in a state where the operating means is prohibited, the operating means may be strongly operated due to an illegal operation or an erroneous operation in such a state. In such a case, the connection control means releases the connection between the operation means and the operation permission means, so that the connection release state detection means enters the detection state. With this, the notifying unit outputs the notifying signal to the outside according to the detection state of the disconnection state detecting unit, so that it is possible to determine that the operating unit has been erroneously operated or erroneously operated based on the notifying signal. It is possible to prevent the operating means and the like from being destroyed.

In the vehicle start control device according to the second aspect of the present invention, the drive means moves the operation permitting means so as to inhibit the operating means from being operated from the travel permitting position to the travel inhibiting position while the vehicle is traveling. Therefore, it is possible to prevent the steering shaft from being locked by the operation means being accidentally operated to the travel prohibited position while the vehicle is traveling.

At this time, when the operating means is strongly operated from the travel-permitted position to the travel-prohibited position, the connection control means releases the connection between the operation means and the operation-permission means, and the connection release state detection means accordingly operates. The detection state is set. As a result, the notification means outputs the notification signal to the outside, and it is possible to determine based on the notification signal that the operating means has been erroneously operated.

In the vehicle start control device according to the third aspect of the present invention, when the operation means is strongly operated by an erroneous operation or an erroneous operation while the movement of the operation permission means is prohibited by the drive means, the connection control means is Since the connection between the operation unit and the operation permission unit is released, the connection release state detection unit is in the detection state. As a result, the notifying unit outputs the notifying signal, so that it is possible to determine an illegal operation or an erroneous operation based on the notifying signal, and it is possible to prevent the operating unit from being destroyed.

In the vehicle start control device according to the fourth aspect of the present invention, if the operating means is strongly operated by an erroneous operation while the drive means has released the movement prohibition state with respect to the operation permitting means, the coupling control means operates the operating means. And disconnect the operation permission means. As a result, the notification means outputs the notification signal, and it is possible to determine the erroneous operation based on the notification signal.

In the case of the vehicle start control device according to the fifth aspect, the operation position detecting means codes and outputs the operation signal, so that the operation signal can be prevented from being illegal.

In the case of the vehicle starting control device according to the sixth aspect, since each means is provided in the closed casing,

Further, when the moderation ball 25 is positioned on the START position slope 27d, the moderation ball 25 is in the ST position.
Since the vehicle is about to go down the ART position slope 27d, the ignition knob 12 is given a rotational force for returning and rotating from the START position to the ON position. In other words, the ignition knob 12 is configured as a momentary type that returns from the START position to the ON position by rotation.

Here, a concentric slit hole 28 is formed in the lock plate 22, and the slit hole 2 is formed.
A curved slide member 29 is attached to the unit 8. An indenter 30 (corresponding to the connection control means 4 shown in FIG. 1) is integrally provided at the tip of the slide member 29, and the indenter 30 is urged by the compression coil spring 31 from the lock plate 22 to the rotary plate 20 side.

The groove 37 is located at the ACC position of the ignition knob 12 and at the ST position.
The lock plate 22 is formed in correspondence with the angle with the ART position, and when the lock pin 35 enters the groove 37, the lock plate 22 has a position corresponding to the ACC position of the ignition knob 12 and a position corresponding to the START position. Rotation is restricted only during this period.

In FIGS. 5 and 6, an engaging protrusion 38 is formed on the shaft 15, and a contact holder 40 having a contact 39 is fixed to the engaging protrusion 38. That is, the contact holder 40 is formed with the through hole 41 having a slit, and the engagement protrusion 38 engages with the through hole 41, whereby the contact holder 4
0 and the shaft 15 are integrated.

On the other hand, an insulator 42 is fixed inside the body 18 so as to face the contact holder 40. A fixed contact is provided on the surface of the insulator 42, and a corresponding rotary position detection switch composed of the fixed contact and the contact 42 (rotation detecting means shown in FIG. 1 is provided in a state where the ignition knob 12 is operated for each operation. (Corresponding to 3) is turned on.

A printed wiring board 43 is arranged in the body 18, and a control circuit (code matching control means 5 and phase difference detection means 7 shown in FIG. 1 is provided on the printed wiring board 43.
And corresponding to the notification means 8). This control circuit drives the electromagnetic solenoid 34 in the state of inputting the proper identification code from the card setting unit 10 and terminates the driving of the electromagnetic solenoid 34 in response to the input of the rotational position signal from the rotational position detection switch. Has become.

The rotary position detecting switch is LOCK.
When the switch corresponding to the position is turned on, for example, "001" is output from the cable 44 as the code signal, and the AC signal is output.
"010" when the switch corresponding to the C position is turned on
Is output, "011" is output when the switch corresponding to the ON position is turned on, and "100" is output when the switch corresponding to the START position is turned on.

A phase difference detection switch 45 (corresponding to the phase difference detection means 7 shown in FIG. 1) is mounted on the printed wiring board 43. The operator 46 of the phase difference detection switch 45 faces the slide member 29 mounted on the lock plate 22 through the curved slit hole 47 formed in the stopper 33. In this case, the control circuit uses the rotational position detection switch and the phase difference detection switch 45.
The warning signal and the warning signal are output to the outside based on the ON state of the, and the buzzer (not shown) is activated or the lamp blinks based on the warning signal and the warning signal.

Next, the steering lock portion 14 will be described with reference to FIGS. 4 and 8. 4 and 8, a slide space 49 having a predetermined shape is provided in the elongated body 48.
Further, a through hole 50 communicating with the slide space portion 49 is formed along the longitudinal direction, and a rectangular frame-shaped lock stopper 51 is slidably arranged in the slide space portion 49. Lock stopper 51 and slide space 49
A compression coil spring 52 is arranged between the inner peripheral wall of the lock stopper 51 and the inner peripheral wall thereof, and the lock stopper 51 is pressed in the arrow B direction by the urging force of the compression coil spring 52.

A long lock bar 53 is inserted into the through hole 50. The base end of the lock bar 53 engages with the lock stopper 51 and the tip end of the lock bar 53 is inserted into the body 4.
It projects from 8. The lock bar 53 protruding from the body 48 is engaged with a recessed portion formed on the steering shaft 54, and the steering shaft 54 and thus the steering wheel 11 are prohibited from rotating in the engaged state.

On the other hand, the slide space 49 in the body 48
A shaft 55 is rotatably supported on the shaft 55, and a cam 56 is provided on the shaft 55. In this case, since the cam 56 is located inside the lock stopper 51, the inner peripheral surface of the lock stopper 51 is in contact with the outer peripheral surface of the cam 56 by the biasing force of the compression coil spring 52.

As shown in FIG. 4, the flexible shaft 16 connected to the shaft 15 of the ignition switch unit 13 is connected to the shaft 55 of the steering lock unit 14, and the ignition knob 12 rotates through the flexible shaft 16. It is adapted to be transmitted to the cam 56.

In this case, the cam 56 locks the lock stopper 51 and the compression coil spring 52 when the ignition knob 12 is positioned between the ACC position and the START position.
It is formed in a shape that moves in the direction opposite to the arrow B against the urging force of the lock stopper 5 by the cam 56.
As shown in FIG. 9, the lock bar 53 is retracted into the body 48 in the moving state 1 to release the rotation prohibited state with respect to the steering shaft 54.

Next, the operation of the above configuration will be described. When the vehicle is stopped, the hole 36 of the lock plate 23
Since the lock pin 35 of the electromagnetic solenoid 34 has penetrated into the lock plate 23, rotation of the lock plate 23 and thus the ignition knob 12 is prohibited. Therefore, rotating the ignition knob 12 is prohibited.

Now, when starting the engine, the IC card is inserted into the card setting section 10. Then, since the identification code stored in the IC card is transmitted from the card setting unit 10 to the control circuit (see FIG. 10A), the control circuit causes the input identification code to match the registration code registered in advance. It is determined whether or not the electromagnetic solenoid 34 is operating, and when they match, the electromagnetic solenoid 34 is driven.

As a result, the electromagnetic solenoid 34 attracts the lock pin 35 against the urging force of the compression coil spring 36, so that the hole 3 of the lock plate 22 is attracted.
The lock pin 35 that has penetrated into 6 escapes from the hole 36, whereby rotation of the lock plate 22 and thus the ignition knob 12 is permitted (see FIG. 7B).

Therefore, the ignition knob 12 is set to LOC.
Start from K position through ACC position and ON position
Rotate to position. At this time, the ignition knob 1
Since the rotary plate 20 and the lock plate 22 integrated with 2 are connected by a predetermined connecting force by the indenter 30 held by the compression coil spring 31,
The lock plate 22 and thus the contact holder 40 are rotated in response to the rotation operation of the ignition knob 12.

As a result, the ignition switch unit 1
Ignition knob 12 from the rotation position detection switch of 3
After the code indicating that was operated to the ON position, ST
A code indicating that the engine has been operated to the ART position is output (see FIGS. 10E and 10F), and the engine is started accordingly.

Since the ignition knob 12 is configured to rotate from the ON position to the START position in a momentary manner, the ignition knob 12 is set to START.
When the rotary operation is released to the position and then the rotary operation is released, the ignition knob 12 automatically returns to the ON position. Therefore, the ignition knob 12 has the same function as a normal ignition key.

As described above, the ignition knob 12
When the vehicle is run after the engine is started by the operation for, the vehicle speed signal is input to the control circuit (see FIG. 10 (g)). Then, the control circuit finishes driving the electromagnetic solenoid 34, and accordingly, the lock pin 35 projects toward the lock plate 22 by the biasing force of the compression coil spring 36.

At this time, the ignition knob 12 is turned on.
Since the lock pin 35 is located at the position, the protruding lock pin 35 enters the groove portion 37 provided on the back surface of the lock plate 22. Here, since the groove portion 37 is provided corresponding to the ACC position to the START position of the ignition knob 12, the ignition knob 12 is restricted to be rotatable only between the ACC position and the START position.
The rotation operation to the OCK position is prohibited (see (b) in the figure).

When the vehicle is stopped, the vehicle speed signal given to the control circuit is cut off, so that the control circuit drives the electromagnetic solenoid 34. As a result, the electromagnetic solenoid 34 attracts the lock pin 35, so that the lock pin 35 that has entered the groove portion 37 of the lock plate 22 escapes from the groove portion 37, so that the rotation operation of the ignition knob 12 is permitted. (See FIG. 10B).

Then, when getting off from the automobile, the ignition knob 12 is rotated to the LOCK position. Then, the control circuit determines that the ignition knob 12 has been operated to the LOCK position based on the detection state of the rotation position detection switch and terminates the drive to the electromagnetic solenoid 35, so that the lock pin 35 projects toward the lock plate 22 side. . At this time, the ignition knob 12 is LOC
Since it is located at the K position, the lock pin 35 enters the hole 36 of the lock plate 22 and enters the ignition knob 1.
The operation for 2 will be prohibited.

Also, the ignition knob 12 is locked.
When rotated to the position, the lock bar 51 comes into engagement with the steering shaft 54 as the cam 56 of the steering lock portion 14 rotates, so that the rotation of the steering shaft 54 and thus the steering wheel 11 is prohibited. become.

By the way, as described above, when the ignition knob 12 is in the LOCK position, the lock plate 22 and thus the ignition knob 12 are prevented from being rotated by the lock pin 35, but the ignition knob 12 is erroneously operated or erroneously operated. When a strong rotation operation is performed, the fact is notified as follows and the ignition knob 12 is prevented from being destroyed.

That is, the ignition knob 12 is locked.
When the rotary plate 20 is rotated with an excessively large force in the position, the indenter 30 that has entered the concave portion 32 of the rotary plate 20 escapes from the concave portion 32 and the lock plate 22.
You will be immersed in it. As a result, the connection between the rotary plate 20 and the lock plate 22 by the indenter 30 is released, and the rotary plate 20 causes a phase difference (angle difference) with respect to the lock plate 22.

At this time, the indenter 30 moves the lock plate 22
The slide member 29 integrated with the indenter 30 protrudes from the lock plate 22 toward the phase difference detection switch 45 side as it is retracted inside. As a result, the operator 46 of the phase difference detection switch 45 is pressed by the slide member 29, and the phase difference detection switch 45 is turned on. Then, the control circuit operates the ignition knob 12
Is in the LOCK position, the phase difference detection switch 4
An alarm signal is output based on that 5 is turned on. (See FIGS. 10 (h) and 10 (i)).

Therefore, the buzzer is activated in response to the output of the alarm signal to give an alarm or the lamp blinks, so that it is possible to notify that an illegal operation or an erroneous operation has been performed, and at the same time the ignition is turned on. It is possible to prevent the knob 12 from being destroyed by excessive force.

Further, although the ignition knob 12 can be rotated between the LOCK position and the START position when the lock pin 35 is disengaged from the lock plate 22, the ignition knob 12 may exceed its operable range. When the erroneous operation is performed, or when the lock pin 35 prohibits the rotation of the lock plate 22 as the vehicle travels, the ignition knob 12 is set to AC.
Although it is possible to operate between the C position and START, if an erroneous operation is performed that exceeds the operable range, the warning is given as follows.

That is, when the ignition knob 12 is erroneously operated beyond the operable range, a phase difference is generated between the rotary plate 20 and the lock plate 22. Will turn on. As a result, the control circuit outputs a warning signal when the phase difference detection switch 45 is turned on while the rotation of the ignition knob 12 is permitted.

Therefore, the buzzer is activated in response to the output of the warning signal to give an alarm or the lamp blinks, so that it is possible to notify that an erroneous operation has been performed and the ignition knob 12 is turned on. It is possible to prevent destruction by excessive force.

According to the above configuration, the rotation operation of the ignition knob 12 normally located at the LOCK position is prohibited, and the operation of the ignition knob 12 is permitted only when the previously registered identification code is given. With this configuration, the user can directly determine whether or not the operation on the ignition knob 12 has been validated by operating the ignition knob 12. Therefore, unlike the conventional example in which the operation feeling for the switch is constant regardless of whether the switch is enabled or not, the usability is excellent.

Also, the ignition knob 12 is locked.
Since the rotation of the steering shaft 54 is prohibited while being operated to the position, the rotation of the steering shaft 54 can be prohibited / permitted in the same manner as in the conventional ignition switch.

Moreover, when the rotation operation of the ignition knob 12 is performed beyond the range in which the ignition knob 12 can be rotated, the fact is notified and the ignition knob 12 is idled. It is possible to notify an erroneous operation and prevent the ignition knob 12 and the like from being destroyed.

Further, since the rotation of the ignition knob 12 can be prohibited or permitted by controlling the energization of the electromagnetic solenoid 34, a simple control can be performed.

Further, since the operation signal output from the rotary position detecting switch in correspondence with the operation position of the ignition knob 12 is coded and output, the security can be improved.

In addition, the rotary plate 20, the lock plate 22, the electromagnetic solenoid 34, the contact holder 4
