2. Description of the Related Art Conventionally, for example, as a device for preventing the door opening of a door lock device due to a fraudulent act from the outside of the vehicle to achieve an antitheft effect, a deadlock operation of a key cylinder or a remote control switch from outside the vehicle is used. Activating the actuator with a deadlock to lock the door lock device of the vehicle, and prevents the lock knob connected to the door lock device for unlocking operation from moving in the unlocking direction to prevent unauthorized operation. There is a device that can prevent the lock operation.

[0003]

However, when the deadlock state is reached, the actuator must be started and the deadlock state must be released to unlock the door lock device. hand,
If you have left the vehicle due to a deadlock operation while operating the electrical equipment such as headlamps,
After that, due to the operation of the electrical equipment, the battery goes up, the power supply to the actuator is stopped,
The unlocking operation of the door lock device may be disabled, and the door may not be opened.

In view of the above problems of the prior art, the present invention solves the conventional problems by making the deadlock operation impossible while the electrical equipment is in operation. An object is to provide a deadlock operating device for a door lock.

[0005]

To achieve the above object, the device of the present invention controls an unlocked state for enabling the door opening operation and a locked state for invalidating the door opening operation. The door lock device that can be used and the drive mechanism is activated by the deadlock operation of the deadlock operation device from the outside of the vehicle to lock the door lock device and operate the door lock device from the locked state to the unlocked state. An actuator that blocks the unlocking operation, an electrical equipment operation detection switch that detects whether the electrical equipment of the vehicle is operating, and an electrical equipment operation detection switch that detects the operating state of the electrical equipment. And a control unit having an invalidation circuit for invalidating the deadlock operation.

[0006]

When the deadlock operation is performed from outside the vehicle while the electrical equipment is not operating, the door lock device actuators of the doors are deadlocked, and the doors are deadlocked. Is blocked. During the deadlock operation, if the electrical equipment is operating and the electrical equipment operation detection switch detects that state, the control circuit will stop the power supply to the actuator and each door will be in a deadlock state. Prevent. Therefore, since the deadlock state does not occur when the electrical equipment is operating, the unlocking operation of the actuator is disabled and the door can be opened due to the battery exhaustion resulting from the operation of the electrical equipment. It can be prevented from running out.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In FIG. 1, (1) shows a door of a driver's seat of a car, a door other than the driver's seat, and a door provided on an opening / closing body such as a trunk lid and a back door (these are also considered as a kind of door) lock. A known electric actuator with an electric deadlock connected to a locking / unlocking lever of the device, which is a key switch (2) interlocked with the operation of a centralized operation switch provided near the driver's seat or a key cylinder provided outside the door. Actuating the actuator (1)
When the motor (3) of FIG. 3 rotates, the locking / unlocking lever of the door lock device enables the door opening operation of the door handle provided on the door, and unlocks the door handle and disables the door opening operation of the door handle. In the locked state, further, the door opening operation of the door handle is invalidated, and the operation from the locked state to the unlocked state of the lock knob for manual locking / unlocking operation, which is connected to the locking / unlocking lever, is blocked to prevent outside the vehicle. It is possible to establish a deadlock state in which the unlocking operation by the fraudulent act from is blocked.

(4) is a knob monitor switch which is provided in the actuator (1) and detects a locked state and an unlocked state of a lock knob connected to a locking and unlocking lever of a door lock device, and (5) is an actuator ( A deadlock monitor switch provided in 1) for detecting the deadlock state of the actuator (1), (6) a trunk switch for detecting the open / closed state of the trunk lid, and (7) an electrical device such as a headlamp. The electrical equipment operation detection switch that detects the operating state of the key switch (2), the knob monitor switch (4), the deadlock monitor switch (5), the electrical equipment operation detection switch (7), respectively, the control unit (8) It is connected to the.

In the control unit (8), the electrical equipment is inactive, the electrical equipment operation detection switch (7) is inactive, and the knob monitor switch (4) of the door lock device of the driver's door is locked. When the key cylinder or the remote control switch, which is the deadlock operating means, is deadlocked from outside the vehicle,
When the motor (3) of the actuator (1) can be activated to put the actuator (1) into a deadlock state, but the electrical equipment is operating and the electrical equipment operation detection switch (7) detects that fact. Has an invalid circuit for controlling so that the motor (3) of the actuator (1) does not start even if a deadlock operation is performed. Further, when the trunk lid is closed and the trunk switch (6) detects the closed state of the trunk lid, the deadlock operation is performed from the outside of the vehicle to immediately output the deadlock operation signal,
When the motor (3) of each actuator (1) is started to enter the deadlock state and the trunk switch (6) detects the open state of the trunk lid, the deadlock operation signal is immediately output. Without storing, the trunk switch (6) outputs a deadlock operation signal when the trunk lid (6) detects the closed state of the trunk lid, and operates each actuator (1) in the deadlock state. It has a control circuit.

Next, the operation of the above embodiment will be described with reference to the flow chart shown in FIG. Insert the key into the key cylinder of the driver's door or lock it with the remote control switch (step S1).
(2) is turned on (step S2). At that time, if the door lock device of the driver's door is unlocked (step S3), the process proceeds to step S4, the door lock device of the driver's door is locked, and the knob monitor switch (4) for the driver's door is set. Detects the locked state (step S5). Next, if the knobs of doors other than the driver's door are not locked (step S6),
When the actuator (1) of the other door operates in the locking direction (step S7), and the door lock device of the other door is locked, the motor (3) of the actuator (1)
Stop (step S8) and all doors are locked (step S8).
It becomes 9).

In step S3, if the door lock device of the driver's door is locked and the knob monitor switch (4) detects the locked state, it is determined that the deadlock operation has been performed,
If the door lock device for another door is locked (step S10), the process proceeds to step S10. At that time, if an electric device such as a headlight is operating and the electric device operation detection switch (7) detects the state.
(Step S11), power supply to the motor (3) of the actuator (1) is stopped (step S8) to prevent the deadlock state. Therefore, the actuator (1) will not be in a deadlock state when the electrical equipment is operated, and the battery will be exhausted.
It is possible to prevent that the unlocking operation of the actuator (1) is disabled and the door cannot be opened.

In step S11, if the electrical equipment is not in operation, the process proceeds to step 12, in which it is determined whether or not all doors including the driver's seat door are in a deadlock state. If it is not in the deadlock state, the process proceeds to step S13. At that time, if the trunk switch (6) detects the closed state of the trunk lid, the actuator of each door
The motor (1) of (1) is deadlocked (step S1
4) After each door lock device is put into the deadlock state, the motor (1) is stopped (step S15), and the door lock devices of all doors and the door lock device of the trunk lid are put into the deadlock state.

In step S13, if the trunk lid is opened and the trunk switch (6) detects the open state of the trunk lid, each actuator (1) is prevented from deadlocking immediately. The deadlock operation is once stored in the memory circuit of the control unit (8). Then close the boot lid (step S1
6) When the trunk switch (6) detects the closed state of the trunk lid (step S13), each actuator (1) is deadlocked (step S14), and the door lock device of each door and the trunk lid is deadlocked. It becomes a state.
When the deadlock monitor switch (5) detects the deadlock state of each actuator (1), each actuator (1) stops (step S15), and all doors and the trunk lid are put into a deadlock state. Therefore, the deadlock operation can be performed with the trunk lid opened, and the operability is improved.

[0014]

As described above, according to the present invention, the deadlock operation is disabled while the electrical equipment is operating, so that the deadlock actuator is caused by the battery exhaustion caused by the operation of the electrical equipment. It is possible to prevent a situation in which power cannot be supplied to the door and the door cannot be opened.
