Abstract

PURPOSE:To prevent mislaying of a key by nullifying locking operation in the case when the key is inserted into an ignition key cylinder at the time of locking and unlocking from outside of a car by a wireless transmitter. CONSTITUTION:At the time when key insertion into an ignition key cylinder is detected by an ignition switch 10 and a lock and unlock memory circuit 15 memorizes an unlocking state, even if a transmitter 11 is operated for locking from outside of a car, it is nullified by a discrimination circuit 20, and locking operation of a door lock with a key inserted into it can be prevented. In the case when it is in the key inserted state and the circuit 15 memorizes a locking state by locking operation of keyless locking operation from outside of the car, unlocking operation of the transmitter 11 is made effective, and door opening by an outside handle is possible. Subsequently, when the switch 10 does not detect key insertion, the circuit 15 is made in the locking or the unlocking state in accordance with locking and unlocking operation of the transmitter 11, and door opening by a door handle is made impossible or possible. Consequently, it is possible to improve a burglary preventiveness and operativity.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door lock operating device for a vehicle, which can be operated in a locked or unlocked state by remote control of a transmitter.

[0002]

2. Description of the Related Art Conventionally, in a door lock operating device that is configured to perform a door lock / unlock operation by remote control using a transmitter capable of transmitting radio waves, etc. By matching the code signal generated with the preset coat signal on the receiver side provided on the vehicle body side, the door lock can be locked or unlocked. Therefore, if the key is inserted into the ignition key cylinder for starting the engine and the lock operation is performed from outside the vehicle using the transmitter, the key remains locked in the ignition key cylinder, and you do not notice it. When the vehicle is separated from the vehicle, there is a problem that an unfavorable situation occurs in anti-theft property.

[0003]

The above-mentioned problems can be solved by disabling the remote control by the transmitter when the key is inserted in the ignition key cylinder, but the keyless lock operation (key and If the door is locked while the key is inserted in the ignition key cylinder by locking the key from the outside of the vehicle without using the transmitter, the transmitter will not be released when the key is inserted in the ignition key cylinder. Since the key operation is disabled, the key is enclosed in the vehicle, which may reduce the operability. In view of the above-mentioned problems of the conventional technique, the present invention prevents a key from being enclosed in a vehicle and improves the anti-theft property and operability of an automobile door lock. The purpose is to provide a device.

[0004]

In order to achieve the above object, the device of the present invention is a door lock provided with a meshing mechanism capable of engaging and disengaging a striker, and a locked state for invalidating a release operation of a door opening operation means. And a locking / unlocking means that can be switched to an unlocked state to be activated, a transmitter that can remotely operate the locking / unlocking means to the locked or unlocked state, and an ignition switch that detects a key insertion state in the ignition key cylinder. In a door lock operating device for a vehicle equipped with, when the ignition switch detects a key insertion state, the locking operation by the transmitter is invalidated, and the determination means for enabling the unlocking operation is provided. I am trying.

[0005]

If the key is inserted into the ignition key cylinder, the ignition switch detects the key insertion, and the locking / unlocking means is in the unlocked state, even if the transmitter is locked, the locking operation is determined by the determining means. The lock / unlock means cannot be put into the locked state by being invalidated by. Therefore, with the key inserted in the ignition key cylinder,
The lock operation of the door lock can be prevented.

[0006] Further, with the key inserted in the ignition key cylinder, when the locking / unlocking means is in a locked state by a keyless lock operation or the like from outside the vehicle, the operation can be performed by unlocking the transmitter. When it is determined to be valid by the determination means, the locking / unlocking means can be unlocked.

It is a voltage conversion unit that supplies a power supply of a predetermined voltage to the main control unit (14).

When the key is inserted in the ignition key cylinder and the ignition switch (10) detects the insertion of the key, the discrimination circuit (20) of the main control unit (14) detects that the transmitter (11) has Although the locking operation is invalidated, it is determined that the unlocking operation is enabled.

Next, the operation of the above embodiment will be described with reference to the flow chart shown in FIG. In step S1, a key is inserted into the ignition key cylinder, the ignition switch (10) detects the key insertion and is in the ON state, and the locking / unlocking memory circuit (15) stores the unlocked state in step S2. Therefore, even if the transmitter (11) is locked from the outside of the vehicle in step S3, the locking operation is invalidated by the discrimination circuit (20) (step S4) and the locking / unlocking memory circuit (15) is locked. It cannot be put into a state. Therefore, it is possible to prevent the door lock (1) from being locked while the key is still inserted in the ignition key cylinder.

In step S2, if the locking / unlocking memory circuit (15) stores the locked state by a locking operation such as a keyless lock operation from the outside of the vehicle while the key is inserted in the ignition key cylinder, if the locked state is stored in the outside of the vehicle in step S5. From transmitter (1
By unlocking 1), the operation is judged circuit (20)
In step S6, the lock / unlock memory circuit (15) can be unlocked (step S7). Therefore, in step S8, by operating the outside handle (3) to open the door, the outside switch (5) is turned on and the motor (16) of the actuator (2) is operated,
Disengage the door lock (1) from the striker, and
You can open (A).

If it is detected in step S1 that the ignition switch (10) is not inserted with any key, the unlocking memory circuit (15) is unlocked by unlocking the transmitter (11) in step S9. Can be unlocked,
The door (1) can be opened. Also, step S10
The locking / unlocking storage means (15) can be brought into the locked state (step S11) by operating the transmitter (11) with the door, and the outside handle (3) or the inside handle (6) is opened in the step S12. Even if the door is opened, the operation is invalidated and the door (A) cannot be opened.

[0017]

As described above, according to the present invention, when the ignition switch detects the key insertion state, the locking operation by the transmitter is disabled and the unlocking operation is enabled. It is possible to prevent the door from being locked while the key is still inserted, and it is possible to exert a great effect on the anti-theft property and to improve the operability.
