Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automobile door lock control device that controls the locked state and unlocked state of an automobile door in response to a control signal sent from an external transmitter.

[Conventional technology]

This type of conventional car door rotor control device receives a control signal sent by radio, ultrasonic, light, etc. from an external transmitter, and when it determines that it is a lock request, it controls the open/closed state of the car door, that is, the closed state. The locking mechanism of the automobile door is controlled to the locking side regardless of whether the door is closed, opened, or the door is left ajar.

[Problem that the invention seeks to solve]

However, when the automobile door is open or ajar (these are collectively referred to as the door open state), the door will not be locked at all or will not be locked completely even if the locking mechanism is activated. On the other hand, since the locking operation by remote control is usually performed at a location away from the automobile, it is difficult for the operator to know that the door is not completely locked. Therefore, with conventional systems that simply drive the locking mechanism to the locking side when a locking request is made regardless of whether the automobile door is open or closed, there is a great possibility that the locking mechanism may be overlooked, and an outsider may easily overlook the locking mechanism. There was a problem in that the door was opened and there was a high risk of theft.

The present invention solves these conventional problems, and its purpose is to not control the locking mechanism to the locking side even if a locking request is made when the automobile door is open, but instead to issue an alarm. An object of the present invention is to provide an automobile door lock control device which is designed to alert an operator to certain conditions.

[Means for solving problems]

In order to achieve the above object, the present invention provides an automobile door lock control device that receives and identifies a control signal 1 from a transmitter to control a locking mechanism 2 of an automobile door, as shown in FIG. a receiver 3 that receives a control signal 1 from the receiver 3; a lock request determining means 4 that determines a lock request based on the control signal 1 received by the receiver 3; a door courtesy switch 5 of an automobile door; When the door opening/closing state determining means 6 determines the open/closed state of the automobile door from the state and the lock request determining means 4 determines a lock request, the door opening/closing state determining means 6 determines that the automobile door is closed. a processing unit that drives a locking mechanism 2 to lock the automobile door when the vehicle door is closed, and issues an alarm to the outside by an alarm means 7 when the door open/close state determining means 6 determines that the automobile door is not closed; 8.

[Effect]

Even if the receiver 3 determines a lock request, if the door courtesy switch is on and the car door is open, the lock mechanism 2 will not be controlled to the lock side, and the alarm means 7 will issue a warning to the operator. Notifies you that the door is open and cannot be locked.

〔Example〕

FIG. 2 is a block diagram of an embodiment of the present invention, in which 10 is a transmitter, 11 is its antenna, 12 is an operation switch, and 13 is a block diagram of an embodiment of the present invention.
is a receiver, 14 is its antenna, 15 is a door courtesy switch, 16 is a door lock/unlock detection switch, 17 is an arithmetic circuit, 18 is an alarm buzzer, 19 is a relay circuit, 20.21 is its contact, and 22 is a Solenoid 23 is a locking mechanism coupled to solenoid 22. The door courtesy switch 15 is a switch that is turned on when the automobile door to which the locking mechanism 23 is attached is in an open state and turned off when it is in a closed state.A door lock/unlock detection switch 16 is provided in association with the solenoid 22. This switch is turned off when the solenoid 22 is driven to the lock side, and turned on when the solenoid 22 is driven to the unlock side.

FIG. 3 is a flowchart showing an example of the door lock control process performed by the arithmetic circuit 17, and 31 to Sll indicate each step. The operation of this embodiment will be explained below with reference to each figure.

When the operation switch 12 is pressed, the transmitter 10 transmits a control signal containing a predetermined code from the antenna 11. This transmitted control signal is received by the antenna 14, and the receiver 13 identifies whether the code matches a code set in the receiver 13 in advance.

If the codes match, the receiver [13] inputs the received control signal to the arithmetic circuit 17.

The arithmetic circuit 17 executes the process shown in FIG. 3 at predetermined intervals, and when a control signal is input from the receiver 13 (S
l) First, the door lock/unlock detection switch 16
If it is off, the received control signal is processed as an unlock request (S6), and if it is on, it is processed as a lock request (S33-35).

Now, assuming that the door lock/unlock detection switch 16 is on and the lock mechanism 23 is in the unlocked state, when the arithmetic circuit 17 receives a control signal, if the door courtesy switch 15 is off, that is, the door is closed. If so, a lock signal is output to the relay circuit 19 (33.34).

As a result, the contact 21 of the relay circuit 19 switches to the power supply +B side, forming a loop of power supply 1B - contact 21 - solenoid 22 - contact 20 → ground, and the solenoid 22 is driven to the side where the locking mechanism 23 is locked. be done. Moreover, this turns off the door lock/unlock detection switch 16.

On the other hand, if the door courtesy switch 15 is on and the door is open, an alarm buzzer sounds (S3, S5).
. The sound of the alarm buzzer 18 allows the operator of the transmitter 10 to know that the door is open and the locking has been unsuccessful. In this case, in this embodiment, when the door is completely closed, it is detected that the door courtesy switch 15 is turned off (S7, S8), and a lock signal is output to the relay circuit 19, thereby locking the door (S9).
, and the alarm buzzer 18 stops sounding (510). In addition, if you want to stop only the alarm buzzer's one-day ringing by remote control, press the operation switch 12 of the transmitter 10 again to send out a control signal, and step S7-Step S8→
The ringing of the alarm buzzer 18 can be stopped by the loop of step 511-step 510.

When the door lock/unlock detection switch 16 is on and the lock mechanism 23 is in the locked state, when the arithmetic circuit 17 receives a control signal (S1, S2), it sends an unlock signal to the relay circuit 19 (S6). ). As a result, the contact 20 of the relay circuit 19 is switched to the power supply +B side, forming a loop of power supply B = contact 20 - solenoid 22 → contact 21 - ground, and the solenoid 22 is connected to the locking mechanism 2.
3 is driven to the unlock side.

In the above embodiment, the control signal from the transmitter 10 is interpreted as either a lock request or an unlock request depending on the current lock state, so that locking and unlocking can be controlled with one operation switch 12. However, the transmitter 10 may be provided with two switches, a lock request switch and an unlock request switch, to transmit different control signals, and to identify them on the receiving side.

〔Effect of the invention〕

As explained above, according to the present invention, if a lock request is made while the automobile door is open, an alarm is issued to the outside, so that the operator does not know from this alarm that the lock has not been made. This has the effect of eliminating the risk of theft due to an incomplete lock being overlooked.
