Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an accelerator interlock device, and more particularly to a control circuit for a solenoid type accelerator interlock device that is interlocked with an automatic door of a bus or the like.

In conventional solenoid-type accelerator interlock control circuits, the solenoid that performs the accelerator interlock operation is simply energized or deenergized in response to switching of a door opening/closing switch.

However, because the solenoid that performs this accelerator interlock operation must be driven by an on-vehicle battery and its installation is limited by space, it is not possible to increase the suction force very much.

Therefore, in the conventional device, there was a problem in that if the driver left the accelerator pedal in a half-depressed state, the solenoid could not push up the accelerator pedal and the accelerator interlock could not be achieved.

This invention was made to solve the above problems.
To provide a solenoid type accelerator interlock control circuit in which a door opening operation is not started until L after an accelerator pedal is interlocked, and the accelerator interlock is not released until after door closing is completed. .

The invention is characterized by a limit switch and a delay 1j that are activated when the armature of the solenoid has traveled a predetermined distance necessary to complete the accelerator interlock operation.

The present invention will be explained below with reference to the accompanying drawings.

The figure is an electrical circuit diagram showing an embodiment of the solenoid type accelerator interlock control circuit according to the present invention.

In the figure, reference numeral 10 denotes a solenoid that performs an accelerator interlock operation. When energized, the armature 12 is attracted and moved linearly in the direction shown by the arrow.

Numeral 14 is a locking member, and a gear formed in part engages with a rack gear formed on the armature 12, and as the armature 12 moves, the locking member 14 rotates in the direction shown by the arrow, and the accelerator pedal 16 is rotated. Push up.

When the armature 12 moves the maximum distance, the locking member 14
reaches the position shown by the broken line, preventing the accelerator pedal 16 from being depressed and completing the accelerator interlock.

20 is a limit switch that turns "on" when armature 12 has moved in the direction of the arrow a predetermined distance sufficient to complete accelerator interlock activation.

Reference numerals 30 and 32 designate first and second relays that respectively control the supply of electricity from the battery 40 to the solenoid 10, of which the first relay 30 is a delay relay having a delayed return contact that returns after a predetermined period of time.

Reference numeral 50 denotes a reversible motor that opens and closes a door for getting on and off (not shown), and rotates forward or reverse depending on the operating position of the door opening/closing switch 52.

54 and 56 are limit switches that operate in conjunction with the door for getting on and off or the motor 50, and the limit switch 54
The contact piece 54a is only opened when the boarding/exiting door is almost completely opened.
is opened, and the contact pieces 56a, 56b of the limit switch 56 are designed to open only when the passenger door is almost completely closed.

58 and 60 are third and fourth relays that are energized to control forward and reverse rotation of the motor 50, respectively.

Next, the operation of the embodiment shown in the figure will be explained.

The figure shows the boarding door closed.

Now, if you turn the door opening/closing switch 52 to the 11 open/11 side,
The eleventh J-ray 30 is energized and the solenoid 10 is energized.

As a result, the solenoid 10 attracts the armature 12 as described above and starts the accelerator interlock operation.

At this time, if the accelerator pedal 16 is half-depressed, the armature 12 cannot move the predetermined distance and the limit switch 20 will not turn on, so the third relay 58
is not energized and the door opening/closing drive motor 50 does not operate.

The limit switch 20 is turned "on" only after the armature 12 moves a predetermined distance (after the accelerator interlock is disengaged).

At this time, the boarding door (not shown) is closed, so the limit switch 54 is "on".
Therefore, the third relay 58 is energized, the motor 50 rotates, and the passenger door is driven to open.

When the door for getting on and off is finished opening, the limit switch 54 is opened and the motor 50 is stopped.

The opening operation of the passenger door will not start until the accelerator interlock is completed in this way.

Next, from this state, turn the door opening/closing switch 52 to I! When tilted to the "closed" side, the contact pieces 56a, 56b of the limit switch 56
is closed, the second relay 32 is energized and the solenoid 10 is energized via the second relay 32.

At this time, since the first relay 30 is deenergized, the solenoid 10 would normally be de-energized momentarily and the accelerator interlock may be disengaged, but as mentioned above, the 11th J relay 30 returns with a delay. This is prevented because it is a delay relay with contacts.

On the other hand, when the door opening/closing switch 52 falls to the 11'' side, the fourth relay 60 is energized (because the contact 56a of the limit switch 56 is closed), and the motor 50 is now turned in the opposite direction. It rotates to drive the boarding/exiting door to close.

When the passenger door is completely closed, the limit switch 56 is turned off, the contact 56a is opened, the fourth relay 60 is deenergized, and the motor 50 is stopped, and at the same time, the contact 56b is opened and the second relay is activated. 32 is deenergized and solenoid 1
0 is stopped, the accelerator interlock is released, and the vehicle is ready to depart.

In this manner, the accelerator interlock is not released until the closing of the passenger door is completed.

In the above-described embodiment, a delay relay having a delayed return contact is used as the first relay 30, but a latching relay having a self-holding function may be used instead.

In this case, for example, in the figure, the 11th J relay 30 is made to have a latching relay structure, the contact part of the second relay 32 is deleted, the coil part of the second relay 32 is considered to be the contact return coil of the latching relay, and the limit is set. The contact piece 56b of the switch 56 may be configured to temporarily close only when the boarding/exiting door is almost completely closed.

As described above, according to the present invention, the opening operation of the passenger door will not start unless the solenoid completes the accelerator interlock, and the accelerator interlock will not be released unless the closing operation of the passenger door is completed. It is extremely safe.
