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

The above-mentioned door lock mechanism capable of deadlock is installed on the driver's seat door and the passenger's seat door or the rear left and right doors of the vehicle. Vehicle antitheft devices that output lock or unlock signals to door lock actuators to lock or unlock all doors, or output set or release signals to deadlock actuators for all doors to set or release Are known.

[0004] Further, there is also known a vehicle antitheft device 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]

Some trunk lock mechanisms have a structure in which when the key cylinder itself is pushed in, the latch mechanism is released and the lock mechanism is unlocked. However, it is possible to provide a switch for detecting the locked / unlocked state in the trunk lock mechanism having such a structure, but 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 this switch changes from the unlocked state to the locked state, all the doors can be interlocked and locked. When the lock mechanism is locked, even if the key cylinder of the trunk is locked, the operation cannot be detected, so that there is a problem that all doors cannot be subsequently deadlocked.

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

[0011]

FIG. 1 is a functional block diagram showing the configuration of an embodiment, and FIG. 2 is a diagram showing operating positions of key cylinders of doors and trunks and operating states of switches. The switch 1 is a switch for detecting a locked state of the driver's seat door, and opens when the door is locked and closes when the door is unlocked. The switch 2 is a position detection switch of a 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 switch for detecting the position of the key cylinder on the front passenger seat.
The side is closed. The switch 4 is a switch for detecting a locked state of the passenger's seat door, and opens when the door is locked and closes when the door is unlocked. The switch 5 is a switch for detecting a locked state of the trunk, and opens when the lock state is established and closes when the unlock state is established. The switch 6 is a trunk open detection switch, and is closed in an 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 locking / unlocking of each door and trunk of the vehicle and setting / release of a deadlock. The controller 10 is supplied with power from a battery BAT of the vehicle.

The controller 2 includes an actuator 2
1 to 29 are connected. The actuators 21 to 24 are actuators for locking / unlocking the driver's seat door, the passenger's 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 / release of door lock mechanisms of the driver's door, the passenger's seat door, the rear left door, and the rear right door, respectively.

When a lock operation or an unlock operation is performed by a driver's door key or a passenger's door key, operation information is sent to the controller 10 by switches 1 to 4,
The controller 10 outputs a lock signal L or an unlock signal UL to the actuators 21 to 25 according to the operation information, and locks / unlocks all doors and trunks in conjunction. In addition, if the deadlock set / release operation is performed using the driver's door key or the passenger's door key,
Operation information is sent to the controller 10 by the switches 1 to 4, and the controller 10 outputs a set signal S or a release signal R to the actuators 26 to 29 according to the operation information, and performs deadlock set / release in conjunction with all doors. .

FIG. 3 is a flowchart showing a trunk clock control program. According to this flowchart,
A lock operation and a deadlock operation of all doors by a key operation of the trunk will be described. The controller 10 starts executing the control program when the unlocked trunk is locked by the key operation of the trunk and the switch 5 is opened from the closed state. In step S1, a timer for measuring an elapsed time from the first trunk lock 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 has been opened to closed, that is, whether or not the locked trunk has been unlocked by the key operation of the trunk.
If unlocked, the process proceeds to step S5. If unlocked, the process proceeds to step S3. In step S3, it is determined by the timer whether two seconds have elapsed since the first lock operation, and if two seconds have elapsed, the process proceeds to step S4, otherwise returns to step S2. That is, if no operation is performed within two 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 doors. At this time, the lock signal L is also output to the actuator 25 of the trunk, but there is no change since the trunk is already mechanically locked.

If the unlock operation by the trunk key operation is performed again after the first trunk lock operation, the process proceeds to step S5, in which the switch 5 is closed or opened, that is, the unlocked trunk is locked again by the trunk key operation. Is determined. If locked, the process proceeds to step S8; otherwise, the process proceeds to step S6. If the trunk is first locked by key operation and then remains unlocked, it is determined in step S6 whether two seconds have elapsed since the first locking operation, and if two seconds have elapsed, step S7 is performed. Otherwise, return to step S5. In other words, if the trunk is unlocked for two seconds after being locked for the first time and remains in that state, an unlock signal UL is output to the actuators 21 to 25 in step S7 to unlock all doors. At this time, the unlock signal UL is also output to the actuator 25 of the trunk, but there is no change since the trunk is already mechanically unlocked.

The trunk is unlocked within 2 seconds after the trunk is first locked by key operation of the trunk, and when the trunk is further locked, the actuator 21 is locked in step S8.
Lock signal L is output 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. That is, when the trunk in the unlocked state is changed from lock to unlock to lock within two seconds by a key operation of the trunk, it is determined that a deadlock operation is performed, and all doors are deadlock set.

FIG. 4 is a flowchart showing a trunk unlock control program. The unlock operation of all doors by the trunk key will be described with reference to this flowchart. The controller 10 operates the switch 5 by unlocking the locked trunk by key operation of the trunk.
Starts the execution of this control program when it is closed from an open circuit. 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, a release signal R is output to the actuators 26 to 29 to release all doors. Next, in step S13, an unlock signal UL is output to the actuators 21 to 25 to unlock all doors. At this time, the unlock signal UL is also supplied to the actuator 25 of the trunk, but there is no change since the trunk is already unlocked by key operation.

As described above, when the trunk in the unlocked state is locked, unlocked, and locked within two seconds by the key operation of the trunk, all the doors are set to deadlock, so that the driver's door or the assistant is bothersome. It is not necessary to return to the seat door and set all doors, which improves usability. Also, when all doors are set,
When the trunk is unlocked and opened, all the doors are linked and released and unlocked, but in such a case, all the doors can be set again by operating the keys on the trunk.

Next, a modification of the above embodiment will be described in which all doors are locked when the trunk key is locked while the trunk is open, and all doors are set when the trunk key is closed and the trunk key is locked. The configuration of this modification is the same as the configuration shown in FIG. FIG. 5 is a flowchart illustrating a trunk lock control program according to a modification of the embodiment. The operation of the modification of the embodiment will be described with reference to this flowchart.
The controller 10 starts executing the control program when the unlocked trunk is locked by the key operation of the trunk and the switch 5 is opened from the closed state.
In step S21, it is determined whether or not the trunk is opened by the switch 6, and if it is opened, the process proceeds to step S2.
Go to step 2, otherwise go to step S23. If the trunk key is locked with the trunk open, a lock signal L is output to the actuators 21 to 25 in step S22 to lock all doors. On the other hand, if the trunk key is locked when the trunk is closed, the actuators 21 to 2 are determined in step S23.
5, a lock signal L is issued to lock all doors, and in a subsequent step S24, a set signal S is sent to the actuators 26 to 29.
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 configuration of the above embodiment, the actuators 21 to 24 serve as door locking means,
29 to 29, the switch 5 constitutes the trunk lock detecting means, the controller 10 constitutes the control means, and the switch 6 constitutes the trunk open detecting means.

[0023]

As described above, according to the present invention, when a predetermined locking / unlocking operation such as locking → unlocking → locking is performed within a predetermined time by the trunk locking means, the vehicle door is opened. Since the door is locked and the door locking means is locked in a locked state, the door can be deadlocked with the key operation of the trunk, and after taking out the luggage from the trunk,
This eliminates the need to return to the door and perform a deadlock, which is convenient. Also, when the trunk is locked when the trunk is open, the vehicle door is locked, and when the trunk is locked when the trunk is closed, the vehicle door is deadlocked. The door lock and deadlock can be selectively executed by the operation, and the operability is improved.In addition, it is necessary to take out the luggage from the trunk and return to the door again to lock and deadlock the door. Not convenient.
