[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door lock control device for controlling the unlocking of a door, and more particularly to a vehicle door lock control device for controlling a door lock including a sliding door.

[0002]

2. Description of the Related Art The development of electronics technology is remarkable, and the technology is used in a very wide range of fields. It is no exception in the field of automobiles, and is widely applied to engine control and other applications under the name of car electronics technology. The advantages of applying electronics technology are its tremendous flexibility and convenience, some of which are becoming essential and some are being replaced by mechanical technology. The technology related to vehicle door locks is also a technology that utilizes its great flexibility and convenience, and contributes to improving the convenience of automobiles. Among them, regarding the unlocking of the sliding door,
There is a situation in which a sliding door moves along a vehicle body, and with the development of car electronics technology, there are various inventions and ideas related thereto.

For example, a device described in Japanese Utility Model Publication No. 62-17568 relates to unlocking of a slide door.
The mechanical operation of a solenoid on the vehicle body side drives the knob mechanism of the slide door to unlock the slide door. Also, the invention described in "Jitsu 1-40926" relates to the unlocking of a sliding door, and this invention is also an electromagnetic drive device (a type of solenoid) provided on the vehicle body side.
Due to the mechanical operation of the above, the knob mechanism of the slide door is driven, and the slide door is unlocked. In these inventions, since the knob mechanism is driven by the solenoid, the solenoid must be enough to drive the knob mechanism that is the load, and the slide door side Since it is a mechanical mechanism called a knob mechanism, it has poor flexibility. In order to improve this point, a vehicle door lock control device has been filed in which car electronics technology is applied to improve the convenience of turning and unlocking a slide door. In these vehicle door lock control devices, an electronic device or an actuator is provided on the sliding door, and the electronic device or the actuator is electrically connected to a control unit mounted on the main body via a connector or a junction switch. Electronic devices and actuators are operated according to the control of. By doing so, the convenience is greatly improved as compared with the mechanical operation of the solenoid described above.

[0004]

With the development of car electronics technology, the number of electronic devices mounted on automobiles has increased, and the power consumption has tended to increase. On the other hand, the capacity of the battery mounted on the car has been demanded to reduce the body weight,
It is not increasing as the increase in electronic devices. Therefore, how to reduce wasteful power consumption is becoming an issue. The above-described vehicle door lock control device is no exception, and the leakage current of the junction switch is a problem. More specifically, when the slide door is open, the electrodes of the junction switch are exposed. In this state, when control is performed to operate the actuator, a voltage is applied from the control unit to the junction switch. Then, depending on the surface condition of the junction switch terminal, electric leakage occurs and the power consumption of the battery increases. In some cases, a short circuit may occur, and corrosion of the vehicle body due to electrolytic corrosion may be caused. As described above, in the conventional vehicle door lock control device, there is a problem that the power consumption is increased due to the leak current of the junction switch in accordance with the demand for low power consumption.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a door lock control device for a vehicle which solves the disadvantages of the prior art and in particular reduces power consumption.

[0006]

SUMMARY OF THE INVENTION The present invention provides a first actuator for unlocking a sliding door of an automobile, a second actuator for unlocking other doors, and A sliding door switch for detecting opening / closing, a rotation lock switch for operating the first and second actuator units, and the first and second actuators according to states of the slide door switch and the rotation lock switch And a junction switch for electrically connecting the first actuator unit and the control unit when the slide door is closed. Further, the first actuator section and the second actuator section are provided in different systems. This aims to achieve the above-mentioned object.

[0007]

When the slide door is opened, it is detected by the slide door switch, and the control unit causes the first actuator unit and the second actuator unit to be provided in separate systems. The part is controlled independently.

In this case, the control unit has output specifications capable of controlling those actuator units, and this is determined when design specifications are determined. Further, the unlocking switch may be an input from a device mounted on the vehicle in advance.

Next, the operation of the embodiment shown in FIG. 1 will be described. When the driver or the passenger operates the knob switch 61 and the manual switch 62 when both the left and right slide doors are closed, the control unit 10 sets the slide door to the “CLOSE” state, and the control unit 10 sets the slide door to the “CLOSE” state, The corresponding output is output to the actuators 21, 22, 31, 32, and 33, and the slide door R actuator 21, the slide door L actuator 22, the front door R actuator 31, the front door L actuator 32, and the back door actuator 33 control the door. The lock is released ("LOCK", "UNLOCK").

When one of the left and right sliding doors is open,
In the control unit 10, the slide door is in the "OPEN" state, and only the operation of "UNLOCK" of the manual switch 62 is effective from the lower part of the table in FIG. 3, and when this operation is performed, the front door R actuator 31, the front door L actuator 32 and back door actuator 3

As shown in FIG. 1, since the first actuator unit and the second actuator unit are provided in different systems, the slide door R actuator 21 and the slide door L actuator 22 do not output any signals, and Of the actuators 31, 32, and 33 can be operated. In particular, only the door was unlocked,
This is to make it easier to close the open door, which is an advantage of the separate system. Further, even if there is a leakage due to the surface state of the junction switches 41 and 42, the slide door R actuator 21 and
Since no output is output to the slide door L actuator 22, invalid power consumption due to electric leakage at the junction switches 41 and 42 is prevented.

As described above, when there is a leakage due to the surface state of the junction switch, the sliding door is moved to the "OP".
In the state of “EN”, if there is an output from the control unit to the slide door R actuator or the slide door L actuator, it is invalid and only invalid power due to earth leakage or the like is consumed. Must also be output from the control unit, which results in the consumption of extra ineffective power and the corrosion of the vehicle body due to electrolytic corrosion. However, as in the above-described embodiment, when the control unit does not output the signal to the slide door R actuator and the slide door L actuator in the state where the slide door is in the “OPEN” state, it is possible to prevent invalid power consumption due to electric leakage or the like. become. And the sliding door is "CLOS
In the state of “E”, when an output is made from the control unit to the slide door R actuator or the slide door L actuator, the output is used to lock the slide door (“LO
CK ”), and the output is valid. Again, there is invalid power consumption, but if this is a problem,
It is greatly improved by improving the fitting structure of the junction switch, thereby largely preventing corrosion of the vehicle body.

[0017]

The present invention is constructed and functions as described above. According to this, there is a leakage due to the surface condition of the junction switch and the like, and the sliding door is "OPE".
In the state of "N", no output is made from the control unit to the sliding door R actuator or the sliding door L actuator, so that invalid power consumption is prevented, whereby corrosion of the vehicle body is prevented and battery life is reduced. It is possible to provide an excellent vehicle door lock control device that can be extended, which has not been achieved before.
