Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a so-called automatic door control device that automatically opens and closes a door using an appropriate drive source such as a motor, hydraulic pressure, vacuum, or the like.

Generally, this type of device is equipped with an opening/closing door switch near the driver's seat, and operating the switch activates the drive source.For example, by opening and closing the rear door, it is possible to improve the ease of getting in and out of the rear seat passengers. I have to. (Refer to Japanese Utility Model Publication No. 13845.) However, when the rear seat passenger forgot that the door was an automatic door and manually operated the inside handle to open the door, the driver operated the opening/closing door switch and opened the door. If the door is opened, the rear seat occupant may get dragged into the door, creating an unfavorable safety situation.

Alternatively, if the driver attempts to open the door by manually operating the outside handle from outside the vehicle, the driver also operates the door switch and opens the door.
There is a risk that your body will be dragged into the door, which could lead to an unfavorable safety situation.

This invention was made in view of the above circumstances, and when the outside or inside handle is operated to manually open a door that operates automatically, the door will not open or close automatically even if the opening/closing door switch is operated. An object of the present invention is to provide a control device for an automatic door in which the drive circuit is opened without manual operation, and the safety is improved by giving priority to manual operation.

In order to achieve this object, the present invention connects a handle switch in series with the opening/closing door switch, which cuts off the operation of the drive source by operating the inside handle or outside handle of the door, which operates automatically.

The embodiment shown in the drawings will be described below.

The figure shows an example of a circuit of an automatic door control device. 1 is an on-vehicle power supply, 2 is a fuse, 3 is an ignition switch, and 4 is an opening/closing door switch that is a switch for operating the automatic door. For example, it is located near the driver's seat. It is normally located at a neutral position, and when the door is opened, the contact 4a side is closed, and when the door is closed, the contact 4b side is closed.

Numeral 5 is a fully open limit switch that is automatically activated and turns off when the rear door is fully opened, and 6 is a fully closed limit switch that is also automatically activated and is turned off when the rear door is fully closed.They are arranged to directly detect whether the door is fully open or fully closed. Alternatively, it may be built into the motor 9, which will be described later. 7 is an interlocking type door inside handle switch (hereinafter referred to as the inside switch) that turns off when the inside handle of the rear door, which operates automatically, is operated to open it from the inside of the vehicle; 8, the outside handle of the rear door, which also operates automatically, is turned off when the door is opened from the inside of the vehicle. This is an interlocking type door outside handle switch (hereinafter referred to as outside switch) that turns off when the door is operated to open. Reference numeral 9 denotes a reversible motor as a drive source for automatically operating the rear door, and by driving this motor 9, the rear door can be pushed open or pulled open or closed via an opening/closing mechanism (not shown).

With this configuration, during normal automatic operation, the inside switch 7 and outside switch 8 are each turned on, so when opening/closing door switch 4 is turned on to contact 4a side, power supply 1 - fuse is turned on. 2-Ignition switch 3-Opening/closing door switch 4 (4a connection)-Limit switch 5-Inside switch 7-Outside switch 8-Motor 9-The ground motor drive circuit is closed and the motor 9 is operated in forward rotation. When the rear door is fully opened, the limit switch 5 is turned off and the motor 9 is stopped. Conversely, when closing the door, when switch 4 is turned on to contact 4b side, power supply 1 - fuse 2 - ignition switch 3 - opening/closing door switch 4 (4b connection) - limit switch 6 - inside switch 7 - outside switch 8 - motor The 9-earth motor drive circuit is closed, the motor 9 is operated in reverse to close the rear door, and when the door is fully closed, the limit switch 6 is turned off and the motor 9 is stopped. If the rear seat passenger attempts to get out of the vehicle and manually operates the inside handle to open the rear door, and immediately after that, the driver turns on the open/close door switch 4 to the open side, the inside switch 7 will turn off. Therefore, the drive circuit for the motor 9 is opened, and the rear door cannot be automatically operated, but can only be opened manually by the rear seat occupant. On the other hand, if the driver turns the opening/closing door switch 4 to the opening side immediately after attempting to open the rear door from outside the vehicle by operating the outside handle, the outside switch 8 will also turn off. The drive circuit for the motor 9 is opened, and the rear door can only be opened manually from outside the vehicle.

As is clear from the above explanation, when an outside handle or an inside handle is operated to manually open or close a door that operates automatically, the door cannot be operated automatically, and manual operation takes priority and is therefore safer.

Note that the outside switch 8 and the inside switch 7 may not be of the interlocking type, but may be switches that are connected in series only to the contact point 4a of the opening/closing door switch 4 and the limit switch 5.

It is also possible to connect a timer circuit to each of the inside switch and outside switch so that after each handle is operated, the switch continues to be turned off for a predetermined period of time and then turned on again.

As described above, according to the present invention, it is possible to improve the safety when passengers get on and off the vehicle through the automatically operated door, and the practical effects are great.
