The present invention relates to a drive control device for a door lock actuator for closing and opening the door by controlling the drive of the door lock actuator installed on the door of the vehicle.

If the door is opened while the vehicle is running, a safety accident occurs that not only is the passenger of the vehicle very dangerous, but also that the open door hits another vehicle traveling next to his vehicle.

Therefore, the door of the vehicle is equipped with a door lock actuator, and the door lock actuator is operated according to the traveling speed of the vehicle and the driver's operation to close and open the door.

That is, when the vehicle is traveling at a predetermined speed or more, the door lock actuator is operated to close the door so that it does not open, and the door lock actuator is operated by operating the lock lever provided in the driver's door to close the door and Open.

The door lock actuator keeps the door closed until the driver releases the closed state by operating the lock lever provided in the driver's door while the door lock actuator is operated to close the door.

The driving control apparatus of the conventional door actuator will be described in detail with reference to the drawings of FIGS. 1 and 2.

1 is a circuit diagram showing the overall configuration of a conventional drive control apparatus. As shown therein, the door lock actuator 1 is installed in the driver's seat door of the vehicle to close and open the door, and the door lock actuators 2 to 4 are installed in the doors other than the driver's door to close and open the door. When the vehicle is traveling at a predetermined speed or more, the door lock actuators 1 to 4 are operated to close the doors, and the door lock actuators 2 to 4 are closed according to the closed and open state of the door lock actuator 1. A control unit 5 for controlling closing and opening of 4) and a relay RY _{1 for} operating the door lock actuators 1 to 4 to close the door by operating as the control unit 5 outputs a closing signal. switch (RYS ₁₎ and the controller 5 is operating as an output signal closing the door lock actuator (1 to 4), the relay to thereby open a door (RY ₂₎ and a relay switch It was composed of (RYS _2).

And a second turn, as a circuit diagram showing a configuration of a door lock actuator (1 to 4) In the illustrated, closed terminals (C ₁₎ is opposite the master (POS ₁₎ and contacts (TA ₁₎ through the motor 11 and the is connected to the anode of the diode (D _1), the open terminal (O ₁₎ the contact point (TA ₃₎ and the diode is connected to the anode of the (D ₂₎ the diode (D _l) a cathode contact of (D ₂₎ (TA ₂ ), a switch 13 connected between the switch terminals S ₁ and S ₂ connected and opened in accordance with the closing and opening of the door.

In the above, the relay switch (RYS ₁ ) (RYS ₂ ) has a movable contact connected to one side fixed contact (a ₁ ) (a ₂ ) when its relay (RY ₁ ) (RY ₂ ) is driven, and the relay (RY _1). ) (the movable contact when RY ₂₎ does not been driven and is connected to the other fixed contact point _{(b 1) (b 2)} .

In the figure, reference numeral B ⁺ denotes a power source, and 12 denotes a connector for selectively connecting the contacts TA ₁ , TA ₂ (TA ₂ , TA ₃ ) according to the opening and closing of the door. In this case, the contacts TA ₁ and TA ₂ are connected, the contacts TA ₂ and TA ₃ are opened, and when the door is completed, the contacts TA ₁ and TA ₂ are opened, and the contacts TA ₂ are opened. , TA ₃ ). The drive control apparatus of the conventional door lock actuator configured as described above switches a door 13 of the door lock actuator 1 by closing the door by operating the lock lever installed in the driver's seat while the power supply B ⁺ is applied. ) Is connected, the low potential is input to the input terminal (IN ₁ ) of the control unit (5).

Then, the controller 5 determines that the door of the driver's seat is closed, and outputs the low-potential closed control signal to the closed output terminal CLO to drive the relay RY ₁ , and the movable contact of the relay switch RYS ₁ . It is connected to the side fixed contact (a _1).

When the movable contact of the relay switch (RYS ₁ ) is connected to one fixed contact (a ₁ ), the power source B ^{+ is} connected to the relay switch (RYS ₁ ), the closed terminal (C ₁ ) of the door lock actuators (1 to 4), Through the pos ₁ , the motor 11, the diode D ₁ , the contact TA ₂ , the connector 12, the contact TA ₃ , the open terminal O ₁ and the relay switch RYS ₂ . Since it flows to the ground, the motor 11 is driven in the forward direction to close the door. When the closing of the door is completed, the connector 12 moves to connect the contacts TA ₁ and TA ₂ and the switch 13. Is connected.

As such, when the door is closed and the contacts TA ₁ and TA ₂ are connected, power is not supplied to the motor 11, so that driving of the motor 11 is stopped and overload is prevented.

Here, the POS POS ₁ prevents the motor 11 from being damaged due to the overcurrent by increasing its resistance when an overcurrent flows to the motor 11.

In addition, as the door is closed and the switch 13 is connected, all low potentials are input to the input terminals IN ₁ (IN ₂ ) of the controller 5, and the controller 5 determines that the door is closed. The high potential is output to the closed output terminal CLO to stop the relay RY ₁ , and the movable contact of the relay switch RYS ₁ is connected to the other fixed contact b ₁ to complete the closing operation of the door.

When the door is opened by operating the lock lever provided in the door of the driver's seat, the switch 13 of the door lock actuator 1 is opened, so that the high potential is input to the input terminal IN ₁ of the controller 5.

then. The control unit 5 determines that the door of the driver's seat is opened, and outputs a low potential open control signal to the open output terminal OPE to drive the relay RY ₂ , and the movable contact of the relay switch RYS ₂ is one side. It is connected to the fixed contact a ₂ .

When the movable contact of the relay switch (RYS ₂ ) is connected to one fixed contact (a ₂ ), the power supply (B ⁺ ) is the open terminal (O ₁ ) diode of the relay switch (RYS ₂ ) and the door lock actuators (1 to 4). Ground via (D ₂ ), contact (TA ₂ ), connector (12), contact (TA ₁ ), motor (11), position (POS ₁ ), closing terminal (C ₁ ) and relay switch (RYS ₁ ) In contrast to the above, the motor 11 is driven in the reverse direction to open the door, and when the opening of the door is completed, the connection port 12 moves to connect the contacts TA ₂ and TA ₃ and switch. (13) is opened.

When the opening of the door is completed as described above and the contacts TA ₂ and TA ₃ are connected, power is not supplied to the motor 11, so that driving of the motor 11 is stopped to prevent overload.

In addition, as the door is opened and the switch 13 is opened, high potentials are all input to the input terminals IN ₁ (IN ₃ ) of the controller 5, and the controller 5 determines that the door is completed. A high potential is output to the open output terminal OPE to stop the relay RY ₂ , the movable contact of the relay switch RY ₂ is connected to the other fixed contact b ₂ , and the opening operations of the door are completed. .

Then, when the vehicle travels, the vehicle speed signal detecting the traveling speed of the vehicle is input to the controller 5.

then. The controller 5 determines whether the vehicle is traveling at a predetermined speed, for example, 40 km or more, using the input vehicle speed signal.

At this time, when the vehicle is traveling at a predetermined speed or more and a high potential is input to the input terminals IN ₁ and IN ₂ and the door is opened, the controller 5 outputs a low potential to the closed output terminal CLO. Thus, the relay RY ₁ is driven. As a result, the motor 11 of the door lock actuators 1 to 4 is driven in the forward direction to close the door as described above.

However, the conventional technology described above has a problem in that the cost of production of the product increases because each of the door lock actuators 1 to 4 uses an expensive POS ₁ for protecting the motor 11.

Accordingly, an object of the present invention is to provide a drive control apparatus for a door lock actuator that does not damage the motor of each door lock actuator using only one positioner.

The drive control device of the door lock actuator of the present invention for achieving the above object is a relay switch for removing the position provided in each door lock actuator, and the movable contact or open drive of the relay switch for closing the door lock actuator This is achieved by connecting a single transistor in series between the movable contact of and the door lock actuator so that power is supplied to the motor through the position when the door lock actuator is opened or closed.

Hereinafter, with reference to the accompanying drawings 3 and 4 will be described in detail.

Therefore, the low potential is input to the input terminal IN ₂₁ of the door part 25.

When the vehicle travels, a vehicle speed signal that detects a traveling speed of the vehicle is input to the controller 5, and the controller 5 determines whether the vehicle runs at a speed higher than a preset speed using the input vehicle speed signal.

At this time, when the low potential is input to the input terminal IN ₂₁ of the control unit 25 or the vehicle travels at a predetermined speed or more, the control unit 25 determines that the door of the driver's seat is closed in the same manner as in the related art, and closes the output. The low potential closed control signal is output to the terminal CLO.

Then, the relay RY ₂₁ is driven, the movable contact of the relay switch RYS ₂₁ is connected to one fixed contact a ₂₁ , and the power source B ⁺ is connected to the relay switch RYS ₂₁ and the POS _21.

Therefore, the motor 31 of the door lock actuators 21 to 24 is driven forward to close the door. When the door is closed, the relay RY ₂₁ outputs a high potential to the closed output terminal CLO. is stopped, the movable contact of the relay switch (RYS ₂₁₎ is connected to the other fixed contact ₍₂₁ b) is returned to original state.

And when the door is opened by operating the lock lever installed in the door of the driver's seat while the door is closed, the switch 13 of the door lock actuator 21 is opened to the input terminal IN ₂₁ of the controller 25. The high potential is entered.

Then, the controller 25 determines that the door of the driver's seat is opened, outputs a low potential open control signal to the open output terminal OPE to drive the relay RY ₂₂ , and activates the movable contact of the relay switch RYS ₂₂ . It is connected to the one side fixed contact a ₂₂ , and the power supply B ⁺ is applied to the open terminal O _{2 l} of the door lock actuators 21 to 24 through the relay switch RYS ₂₂ and the door lock actuator 21. Since the closing terminal C _{2l of ˜24} is grounded through the position sensor POS ₂₁ and the relay switch RYS ₂₁ , the motor 31 of the door lock actuators 21 to 24 is driven backward to open the door. When the opening of the door is completed, the relay RY ₂₂ is stopped by outputting a high potential to the open output terminal OPE, and the movable contact of the relay switch RYS ₂₂ is connected to the other fixed contact point b ₂₂ . It is restored to its original state.
