Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle antitheft device for double locking a vehicle door.

[0002]

2. Description of the Related Art There is known a vehicle antitheft device which locks a locked vehicle door so that it cannot be unlocked (for example, see Japanese Utility Model Publication No. 4-24046). In this specification, locking / unlocking of a door is referred to as locking / unlocking, and a locking method for locking the door and restraining the door lock mechanism so as not to shift from the locked state to the unlocked state is dead. Call it lock. Further, deadlocking the door is called set, and releasing the deadlock is called release, which is distinguished from mere door locking and unlocking.

Further, the above deadlockable door lock mechanism is installed on the driver's door and the passenger's door of the vehicle, or on the left and right doors of the rear seat. A vehicle anti-theft device that outputs a lock signal or an unlock signal to the door lock actuator to lock or unlock all doors, or outputs a set signal or release signal to the deadlock actuators of all doors to set or release Are known.

Further, a vehicle antitheft device is also known in which a lock mechanism is also provided in a key cylinder of a trunk and the trunk is locked / unlocked in conjunction with locking / unlocking of each door.

[0005]

By the way, as a lock mechanism of the trunk, there is a structure in which when the key cylinder itself is pushed in, the latch mechanism is opened and the lock mechanism is unlocked. However, although it is possible to provide a switch for detecting the locked / unlocked state in the trunk lock mechanism having such a structure, it is structurally difficult to provide a switch for detecting the operation position of the key cylinder.

Therefore, a switch for detecting the locked / unlocked state of the lock mechanism of the trunk is used, and when the switch changes from the unlocked state to the locked state, all the doors can be interlocked and locked, but once the trunk When the lock mechanism of is locked, the operation cannot be detected even if the key cylinder of the trunk is locked, so that there is a problem in that all the doors cannot be deadlocked subsequently.

It is an object of the present invention to provide a vehicle antitheft device capable of locking and deadlocking all doors by operating a trunk key.

[0008]

The present invention will be described with reference to FIG. 1 showing an embodiment. According to the invention of claim 1, door locking means 21 to 24 for locking a vehicle door and the door locking means are provided. It is applied to a vehicle antitheft device provided with door restraining means 26 to 29 for restraining the means 21 to 24 in a locked state so that they cannot be unlocked, and a trunk locking means 25 for locking the trunk of the vehicle. Then, the trunk lock detecting means 5 for detecting the locked state of the trunk lock means 25 and the door lock when the trunk lock detecting means 5 detects a predetermined lock / unlock operation of the trunk lock means 25 within a predetermined time. The doors are locked by the means 21 to 24, and the control means 10 that locks the door locking means 21 to 24 by the door restraining means 26 to 29 are provided, thereby achieving the above object. In the vehicle antitheft device according to a second aspect of the present invention, the predetermined locking / unlocking operation is an operation in which the trunk locking means 25 in the unlocked state is locked, then unlocked, and then locked again. According to the invention of claim 3, the door locking means 21 to 24 for locking the door of the vehicle and the door locking means 2 for locking the door locking means 21 to 24 in a locked state so that they cannot be unlocked.
It is applied to a vehicle antitheft device including 6 to 29 and a trunk locking means 25 for locking the trunk of the vehicle. Then, the trunk lock detecting means 5 for detecting the locked state of the trunk lock means 25, the trunk open detecting means 6 for detecting the open state of the trunk, and the trunk lock detecting means 6 when the trunk open is detected. When the detecting means 25 detects the operation from the unlocked state to the locked state, the door locking means 21 to 24 lock the door,
When the trunk lock detecting means 5 detects an operation from the unlocked state to the locked state while the trunk opening detecting means 6 detects the trunk closing, the door locking means 21 to 21.
After locking the door by 24, door restraining means 26-29
Control means 10 for restraining the door locking means 21 to 24 by
And to achieve the above object.

[0009]

When the trunk locking means 25 performs a predetermined locking / unlocking operation such as locking → unlocking → locking within a predetermined time, the vehicle door is locked, and further the door locking means 21 to 21.
24 is locked. This makes it possible to deadlock the door by operating the key of the trunk, which is convenient because it is not necessary to return to the door and deadlock again after taking out the luggage from the trunk. Further, when the trunk is unlocked, the door of the vehicle is locked, and when the trunk is locked, the door of the vehicle is deadlocked. As a result, door lock and deadlock can be selectively performed by key operation on the trunk, improving operability, and after taking out luggage from the trunk, return to the door again and lock the door. It is convenient because there is no need to perform deadlock.

Incidentally, in the section of means and action for solving the above problems for explaining the constitution of the present invention, the drawings of the embodiments are used for the purpose of making the present invention easy to understand. It is not limited to.

[0011]

1 is a functional block diagram showing the construction of an embodiment, and FIG. 2 is a diagram showing the operating positions of the door and trunk key cylinders and the operating states of the switches. The switch 1 is a lock state detection switch for the driver's door, and opens in the locked state and closes in the unlocked state. The switch 2 is a position detecting switch for the driver's seat key cylinder, and the S side is closed at the set position and the R side is closed at the release position.
The switch 3 is a position detection switch for the passenger's seat key cylinder, and the S side is closed at the set position and R at the release position.
The side closes. The switch 4 is a lock state detection switch for the passenger seat door, and opens in the locked state and closes in the unlocked state. The switch 5 is a trunk lock state detection switch, and opens in the locked state and closes in the unlocked state. The switch 6 is a trunk open detection switch, and is closed in the open state. These switches 1 to 6 are connected to the controller 10, and information on each door and trunk is sent to the controller 10.

The controller 10 is composed of a microcomputer and its peripheral parts, and controls lock / unlock of each vehicle door and trunk, and set / release of deadlock. The controller 10 is supplied with power from the battery BAT of the vehicle.

The controller 10 has an actuator 2
1 to 29 are connected. The actuators 21 to 24 are actuators for locking / unlocking the driver seat door, the passenger seat door, the rear left door, and the rear right door, respectively. The actuator 25 is an actuator for locking / unlocking the trunk. Further, the actuators 26 to 29 are actuators for deadlock setting / releasing the door lock mechanism of the driver seat door, the passenger seat door, the rear left door, and the rear right door, respectively.

When the driver door key or the passenger door key is used to perform a lock operation or an unlock operation, operation information is sent to the controller 10 by the switches 1 to 4,
The controller 10 outputs the lock signal L or the unlock signal UL to the actuators 21 to 25 in accordance with the operation information, and locks / unlocks all the doors and the trunk in cooperation with each other. Also, if the deadlock set / release operation is performed using the driver's door key or the passenger's door key,
The operation information is sent to the controller 10 by the switches 1 to 4, and the controller 10 outputs the set signal S or the release signal R to the actuators 26 to 29 according to the operation information to interlock all doors to set / release the deadlock. .

FIG. 3 is a flowchart showing the trunk lock control program. According to this flowchart,
The lock operation and deadlock operation of all doors by key operation of the trunk will be described. The controller 10 starts execution of this control program when the unlocked trunk is locked by the key operation of the trunk and the switch 5 is opened from the closed circuit. In step S1, a timer for counting the elapsed time from the first trunk clock operation is started. In this embodiment, the reference time for determining a deadlock operation is, for example, 2 seconds. In a succeeding step S2, it is determined whether or not the switch 5 is closed from the open state, that is, whether or not the trunk in the locked state is unlocked by the key operation of the trunk.
If unlocked, the process proceeds to step S5, and if not unlocked, the process proceeds to step S3. In step S3, it is determined by the timer whether or not 2 seconds have elapsed from the first lock operation. When 2 seconds have elapsed, the process proceeds to step S4, and if not, the process returns to step S2. That is, if no operation is performed within 2 seconds after the first lock operation is performed by the key operation of the trunk, the lock signal L is output to the actuators 21 to 25 in step S4 to lock all the doors. At this time, the lock signal L is also output to the actuator 25 of the trunk, but since the trunk has already been mechanically locked, there is no change.

After the first trunk lock operation, when there is an unlocking operation by the trunk key operation again, the process proceeds to step S5, and the switch 5 is closed to open, that is, the trunk key operation again locks the unlocked trunk. It is determined whether or not. If locked, the process proceeds to step S8, and if not, the process proceeds to step S6. When the trunk is first locked by the key operation and then unlocked, it is determined in step S6 whether or not 2 seconds have elapsed from the initial locking operation, and if 2 seconds has elapsed, step S7 is performed. Otherwise go to step S5. That is, the trunk is unlocked within two seconds after being locked for the first time, and if it remains in that state, the unlock signal UL is output to the actuators 21 to 25 in step S7 to unlock all the doors. At this time, the unlock signal UL is also output to the actuator 25 of the trunk, but there is no change because the trunk has already been mechanically unlocked.

When the trunk is first locked by the key operation of the trunk, the trunk is unlocked within 2 seconds, and when the trunk is further locked, the actuator 21 is operated at step S8.
Output a lock signal L to ~ 25 to lock all doors,
In a succeeding step S9, a set signal is output to the actuators 26 to 29 to deadlock set all the doors. In other words, when the unlocked trunk is locked → unlocked → locked within 2 seconds by the key operation of the trunk, the deadlock operation is determined and all the doors are deadlocked.

FIG. 4 is a flowchart showing a trunk unlock control program. With this flowchart, the unlocking operation of all the doors by the trunk key will be described. The controller 10 switches the switch 5 when the locked trunk is unlocked by operating the trunk key.
When is closed, the control program starts executing. In step S11, it is determined whether or not the door is in the set state by the switches 1 to 4. If the door is set, the process proceeds to step S12, and if not, the step S12 is skipped. In step S12, the release signal R is output to the actuators 26 to 29 to release all the doors. Next, in step S13, the unlock signal UL is output to the actuators 21 to 25 to unlock all the doors. At this time, the unlock signal UL is also supplied to the actuator 25 of the trunk, but since the trunk has already been unlocked by the key operation, there is no change.

In this way, if the trunk which is in the unlocked state is locked → unlocked → locked within 2 seconds by the key operation of the trunk, all the doors are set to the deadlock. There is no need to return to the seat door and set all doors, which improves usability. Also, when all the doors are set,
When the trunk is unlocked and opened, all the doors are released and unlocked in conjunction, but even in such a case, all the doors can be set again by key operation of the trunk.

Next, a modification of the above embodiment will be described in which all the doors are locked when the trunk key is locked while the trunk is open, and all the doors are set when the trunk is closed and the trunk key is locked. The configuration of this modified example is the same as the configuration shown in FIG. 1, and therefore illustration and description thereof will be omitted. FIG. 5 is a flowchart showing a trunk lock control program of a modified example of the embodiment. The operation of the modified example of the embodiment will be described with reference to this flowchart.
The controller 10 starts execution of this control program when the unlocked trunk is locked by the key operation of the trunk and the switch 5 is opened from the closed circuit.
In step S21, it is determined whether or not the trunk is opened and entered by the switch 6, and if it is opened and entered, step S2
2. If not, proceed to step S23. When the trunk key is locked while the trunk is open, the lock signal L is output to the actuators 21 to 25 in step S22 to lock all the doors. On the other hand, when the trunk key is locked while the trunk is closed, the actuators 21 to 2 are operated in step S23.
The lock signal L is output to 5 to lock all the doors, and the actuators 26 to 29 receive the set signal S in step S24.
Is output and all doors are set.

The method of operating the trunk key for deadlocking the vehicle door from the trunk side is not limited to the above-described embodiment.

In the construction of the above embodiment, the actuators 21 to 24 serve as door locking means and the actuator 26.
.About.29 constitute door restraining means, switch 5 constitutes trunk locking detection means, controller 10 constitutes control means, and switch 6 constitutes trunk opening detection means.

[0023]

As described above, according to the present invention, when the trunk locking means performs a predetermined locking / unlocking operation such as locking → unlocking → locking within a predetermined time, the vehicle door is opened. Since the door is locked and the door locking means is restrained in the locked state, the door can be deadlocked by key operation on the trunk, and after the luggage is taken out from the trunk,
It's convenient because you don't have to go back to the door to deadlock again. Also, when the trunk is locked when the trunk is opened, the vehicle door is locked, and when the trunk is locked when the trunk is locked, the vehicle door is deadlocked. The door can be selectively locked and deadlocked by operation, improving operability, and it is necessary to return to the door again after the luggage is taken out from the trunk to lock and deadlock the door. Not convenient.
