Abstract

PURPOSE:To improve a function by a method wherein each time a lock state is constrained or released, the operation is stored, and when a constraining or release command is outputted, operation is performed only when release or constraining operation is stored. CONSTITUTION:Each time a lock state is constrained or released by a constraining means 501, the operation is stored at a memory means 503. When a constraining command for a locked state is outputted by a command means 502, a drive control means 504 is operated such that a door lock mechanism 500 is constrained to a locked state by the means 501 only when a constrained state is stored at the means 503. In a drive control means 504, when constrainment releasing command is outputted by the means 502, the mechanism 500 is released from constrainment by the means 501 only when constraining operation is stored in the means 503. Further, in a drive control means 504A, in a case of an ignition key switch, when constraining operation is stored at the means 503, a start is blocked by means of a start blocking means 505. This constitution prevents the generation of a useless load and the occurrence of wasteful consumption of a power and a burglar.

Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art There is known a vehicle antitheft device that locks a locked vehicle door in a locked state so that it cannot be unlocked (see, for example, Japanese Utility Model Publication No. 4-24046).

In this specification, in addition to locking the door,
Further, a locking method for locking the door lock mechanism so as not to shift from the locked state to the unlocked state is called deadlock. Also, deadlocking the door is called set, and releasing the deadlock is called reset, and it is distinguished from mere door locking and unlocking.

In the above conventional anti-theft device, when the key is inserted into the key cylinder of the door and turned to the lock position, a lock signal is output from the controller to the door lock actuators of all the doors of the vehicle, and the door lock actuator is provided for each door. Is activated and the door is locked by the door lock mechanism. When the key is further turned to the set position, the set signal is output from the controller to the deadlock actuators of all doors, the deadlock actuator operates for each door, the stopper is inserted into the door lock mechanism, and the door is set. .

[0005]

However, in the conventional vehicle antitheft device, when the key is turned to the set position, the set signal is output to the deadlock actuator even when the door is deadlocked. There is a problem in that the lock actuator is driven while being restrained, an unreasonable load is applied to the deadlock mechanism, and a restraining current flows to consume unnecessary power.

When the key is turned to the unlock position, the reset signal is output to the deadlock actuator even after the deadlock has been released, and the unlock signal is then output to the door lock actuator. There is a problem that it takes a long time to be unlocked, and the deadlock actuator is driven while being constrained to impose an unreasonable load on the deadlock mechanism, resulting in a constraint current flowing and wasting power.

An object of the present invention is to prevent unnecessary operation of an actuator in a vehicle antitheft device.

[0008]

The present invention will be described with reference to FIG. 1, which is a diagram for responding to claims. According to the invention of claim 1, the door lock mechanism 500 of a vehicle is locked in a locked state so that it cannot be unlocked. The invention is applied to a vehicle antitheft device including a restraint means 501. And command means 502 for outputting a lock state restraint command and a lock release command,
Each time the restraint means 501 performs the restraint operation and its release operation, the storage means 503 stores those actions.
Then, when the lock command of the locked state is output from the command unit 502, only when the lock release operation is stored in the storage unit 503, the lock unit 501 locks the door lock mechanism 50.
When 0 is locked in a locked state and a command for releasing the constraint is output from the command unit 502, drive control for releasing the constraint of the door lock mechanism 500 by the constraint unit 501 only when the constraint operation is stored in the storage unit 503. And means 504 for accomplishing the above objective. Further, the vehicle antitheft device according to claim 2 is provided with a starting prevention means 505 for preventing the vehicle from starting, and when the drive control means 504A turns on the ignition key switch 506 of the vehicle,
When the restraining operation is stored in the storage means 503, the start preventing means 505 prevents the vehicle from starting.

[0009]

In the vehicle antitheft device according to the first aspect, when the lock restraint command is output, the restraint means 501 restrains the door lock mechanism 500 in the locked condition only when the vehicle door is not restrained in the locked condition. When the lock release command for releasing the lock is output, the lock of the door lock mechanism 500 by the lock 501 is released only when the vehicle door is locked in the lock state. Thus, the restraint means 501 in the restraint state is further driven to the restraint side, or the restraint means 501 in the restraint release state is further driven to the release side without providing the restraint state and release state detection means. Unnecessary load is applied to the lock mechanism, or the restraint means 50
It is prevented that a restricted current flows through the actuator of No. 1 and wastes electric power. According to the vehicle antitheft device of the second aspect, the vehicle is prevented from starting if the door of the vehicle is locked in the locked state at the time of turning on the ignition. As a result, it is possible to prevent the vehicle from operating with the door being locked in the locked state.

FIG. 8 is a flowchart showing a lock processing routine by the driver's seat door key. Controller 1
The microcomputer executes this processing routine when the driver's door state switch 112 changes from closed (ON) to open (OFF), and drives the door lock actuators 211, 311 and 411 in steps S1 to drive the doors other than the driver's seat. Lock the door. In the driver's door, the door lock mechanism unit 110 is mechanically driven to the locked state by the key rod 124 that interlocks with the door key as described above.

FIG. 9 is a flow chart showing a setting processing routine by the driver's seat door key. The setting operation will be described with reference to this flowchart. The microcomputer of the controller 1 has a key set switch 125
When is closed (ON), execution of this processing routine is started. In step S11 after the start of execution, the actuators 211, 311 and 411 are driven to lock the doors other than the driver's seat. The driver's door is mechanically locked in conjunction with the door key. In the following step S12, it is determined whether or not the doors other than the driver's seat have been locked by the state switches 212, 312, 412. When the lock is completed, the process proceeds to step S13. In step S13, it is determined whether the power supply from the ignition power supply 3 is stopped, that is, whether the ignition is turned off. If the ignition is turned off, the process proceeds to step S14, and if not, the process proceeds to step S18.

The ignition key is ON or S
A state in which the ignition power supply 3 is in operation at the TART position is called an ignition on state, and a state in which the ignition key is in the ACC or OFF position and the ignition power supply 3 is stopped is called an ignition off state.

In step S14, it is determined whether or not the set switch 125 has been kept in the ON state for 1 second, that is, whether or not the driver's seat door key remains set in the set position. If it is set in the set position, the process proceeds to step S15. If not, the process proceeds to step S18. In step S15, it is determined whether the flag F of the memory 1m is reset (0), that is, whether the vehicle door is in the reset state,
If it is in the reset state, the process proceeds to step S16, and if not, the process ends. When the door of the vehicle is in the reset state, the deadlock actuators 213, 313, 413 are driven to set doors other than the driver's seat in step S16, and the process proceeds to step S17. The driver's seat door is mechanically set in association with the door key as described above. In step S17, the flag F of the memory 1m is set (1), and the process ends.

On the other hand, when the ignition is not turned off, or when the driver's door key is not set to the set position, it is determined in step S18 whether or not the state switch 112 is closed (ON), and the circuit is closed (ON). ), The process proceeds to step S19 and the actuators 211, 31
1, 411 are driven to unlock doors other than the driver's seat. If the circuit is not closed (ON), the process ends with all the doors in the locked state.

FIG. 10 is a flow chart showing an unlock / reset processing routine by the driver's seat door key. The unlocking and resetting operations will be described with reference to this flowchart. The microcomputer of the controller 1 starts execution of this processing routine when the state switch 112 is closed (ON) while the set switch 125 is OFF. First, in step S31, it is determined whether the flag F of the memory 1m is set, that is, whether the vehicle door is in the set state,
If it is in the set state, the process proceeds to step S32, and if not, the process proceeds to step S34. In step S32, the deadlock actuators 213, 313, 413 are driven to reset the doors other than the driver's seat, and the process proceeds to step S33. In step S33, the flag F is reset (0). Next, in step S34, the door lock actuators 211, 311 and 411 are driven to unlock the doors other than the driver's seat. The driver's door is mechanically reset and unlocked as described above.

FIG. 11 is a flow chart showing a reset processing routine by the passenger seat door key. The reset operation will be described with reference to this flowchart. In the reset operation with the passenger door key, the key cannot be turned in the unlock direction because the passenger door itself is in the set state.Therefore, first rotate the key to the locked position to reset it, and then rotate it to the unlock position to unlock it. Follow the procedure below. The microcomputer of the controller 1 has the reset switch 2 when the passenger door key is turned to the locked position.
When 25 is closed (ON), execution of this processing routine is started. First, in step S41, it is determined whether the flag F of the memory 1 is set, that is, whether the vehicle door is in the set state. If it is in the set state, the process proceeds to step S42, and if not, the process proceeds to step S44. If it is in the set state, the deadlock actuators 213, 313, 413 are driven in step S42 to reset the doors other than the driver's seat. In step S43, the flag F is reset (0), and the process proceeds to step S44, in which it is determined whether the passenger's seat door key is turned to the unlock position and the state switch 212 is closed (ON). If closed, the process proceeds to step S45, and if not, the process ends. In step S45, the driver's door status switch 11
It is determined whether 2 is OFF and the set switch 125 is ON, that is, whether the driver's seat door is set. If it is set, the process proceeds to step S46, and if not, the process proceeds to step S47. When the driver's seat door is set, the actuator 2 is set in step S46.
The doors other than the driver's seat are unlocked by driving 11, 311 and 411. On the other hand, when the driver's seat door is not set, the actuators 111, 21 are operated at step S47.
1,311,411 are driven to unlock all the doors.

FIG. 12 is a flowchart showing a processing routine when the ignition is turned on. With this flow chart, the operation of permitting or not permitting the starter motor 7 to start will be described. The microcomputer of the controller 1 executes this processing routine when power is supplied from the ignition power supply 3. First, in step S51, it is determined whether or not the set switch 125 of the driver's door is on, and if the driver's door is in the set state and the set switch 125 is on, step S53.
Otherwise proceeds to step S52. In step S52, it is determined whether or not the flag F indicating the set state of the vehicle door is set, and if it is set, the process proceeds to step S53, and if not, step S54.
Go to. When the vehicle door is set, the vehicle cannot be operated. Therefore, even if the ignition is turned on when the vehicle door is in the set state in step S53, the starter motor 7 is prevented from starting.
That is, the transistor 1t is turned on to turn on the starter cut relay 6, and the relay contact 6a cuts off the starter motor drive circuit so that power is not supplied to the starter motor 7 even if the ignition switch 5 is closed.

On the other hand, the driver's door is in the reset state,
Further, when the flag F is reset, the vehicle door is in the reset state, and the starter motor 7 is permitted to start in step S54. That is, the transistor 1t
Turn off. As a result, the relay 6 is turned off and the relay contact 6a is closed. In this state, when the ignition switch 5 is closed due to the ignition start operation, a current flows from the ignition power supply 3 to the starter motor 7 via the ignition switch 5 and the relay contact 6a, the starter motor 7 rotates and the engine starts. Done.

As described above, when the driver's seat door key is set, the deadlock actuator is driven to the set side to set the door only when the vehicle door is in the reset state, and the driver's seat door key or the passenger seat door key is used. When the reset operation is performed, the deadlock actuator is driven to the reset side to reset the door only when the vehicle door is in the set state, so the set state and the reset state detection device are not provided, and the set state is set. The door lock mechanism part in is further driven to the set side by the deadlock actuator, or the door lock mechanism part in the reset state is further driven to the reset side to apply an unreasonable load to the door lock mechanism part, Constrain current to the deadlock actuator in some parts to consume unnecessary power It can be prevented. Further, if the vehicle door is set when the ignition is turned on, the vehicle is prevented from starting, so it is possible to prevent the vehicle from operating with the door still set.

The command means for outputting the set command and the reset command of the door are not limited to the set switch and the reset switch of the above-mentioned embodiment.

When an engine control device for controlling the operation of the engine is provided, if the vehicle door is set when the ignition is turned on, the controller 1 sends an engine start inhibition signal to the engine control device, and the engine control device side The engine may not be started by shutting off the ignition power source or stopping the fuel supply to the engine.

Further, in the above-mentioned embodiment, when the vehicle door is set, the starter motor drive circuit is cut off to prevent the engine from starting. However, for a vehicle equipped with an automatic match transmission, Send a signal to the shift lock control unit,
The select lever may be locked in the parking position.

In the configuration of the above embodiment, the door lock mechanism parts 110, 210, 310 and 410 are the door lock mechanism and the restraining means, the set switch 125 and the reset switch 225 are the command means, and the memory 1m is the storing means. The controller 1 constitutes drive control means.

[0044]

As described above, according to the invention of claim 1, when the lock restraint command is output, the restraint means locks the door lock mechanism only when the vehicle door is not restrained in the locked condition. When the vehicle is locked in the locked state and a command to release the locked state is output, the locking of the door lock mechanism by the locking means is released only when the vehicle door is locked in the locked state. And without providing the detection means of the released state, the restraint means in the restrained state is further driven to the restraint side, or the restraint means in the released state of the restraint is further driven to the release side to apply an unreasonable load to the door lock mechanism. It is possible to prevent unnecessary power consumption by applying a constraint current to the actuator of the constraint means.
Furthermore, if the unlocking operation is performed when the door is not locked in the locked state, the unlocking operation is immediately performed without performing the unlocking operation, so that there is no operation delay during the unlocking operation and the operational feeling is improved. According to the second aspect of the invention, the vehicle is prevented from starting if the door of the vehicle is locked in the locked state when the ignition is turned on. Therefore, the vehicle is operated while the door is locked in the locked state. Can be prevented.
