Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door lock control device for locking or unlocking a vehicle door by remote control using a remote controller. The present invention relates to a door lock control device provided with a closer mechanism for completely closing the door.

[0002]

2. Description of the Related Art Conventionally, this type of device has been disclosed as a wireless door lock device using a remote controller as disclosed in Chapter 4, pages 86 to 97 of Century New Vehicle Manual (issued by Toyota Motor Corporation in April 1997). And a door closer that closes the door from the half-door state to the fully-closed state (hereinafter, the door closer)
(Referred to as a closer)).

Usually, a remote controller for requesting a door lock device of a vehicle to lock or unlock a door is carried by a user, and a receiver for receiving a request signal from the remote controller is provided on the vehicle side. The door lock device is controlled based on a signal from a door state detection switch attached near the door and an IG key for detecting whether a vehicle key is inserted into the key cylinder.

In this case, the wireless door lock device is
For example, after detecting that the door has been opened and closed and that the vehicle key has been removed from the key cylinder, the vehicle receives a request signal (a door lock request signal, etc.) of a remote controller operated by the user. When the door is locked by operating the door lock device, or when the vehicle is locked when the vehicle is parked, an unlock request is output to the vehicle, and the door lock device is unlocked.

In addition to this function, a switch for detecting a door state (half-door state, fully-closed state, etc.) is used, and when the door is in a half-door state after parking, the door is automatically switched from the half-door state to the fully-closed state. A door closer mechanism for closing the door has been added.

[0006]

However, in the above-described door lock device provided with a closer mechanism, the closer is operated so as to close the door from a half-door state to a fully-closed state. In the middle, the request signal from the remote controller is not accepted until the door is fully closed.

For this reason, the user (particularly, the driver) has to wait for the remote control operation until the closer operation is completed, which results in poor operability. In this case, if the user operates the remote control while walking away from the vehicle without noticing that the door is in the half-door state, the user may operate the remote control and perform the locking operation, but the remote control will not be performed during the closer operation. Since the request signal cannot be received from the remote controller and the request from the remote controller cannot be received, the door is unlocked and the anti-theft property is poor.

In view of the above, the present invention has been made in view of the above-mentioned problems. The present invention reliably responds to a request signal from a remote controller even during the operation of a closer, improves anti-theft properties, and reliably reflects the intention of the user. A technical task is to make the device capable of being used.

[0009]

The technical measures taken to solve the above-mentioned problems include a remote control which is carried by a user and remotely controls a lock and unlock request of a vehicle door, and a door provided on the vehicle side. A door lock control device comprising: a door state detecting means for detecting an open / close state of the door; and a close function for operating the door state detecting means to bring the door into a fully closed state when the door is in a half-door state. When a request signal is issued from the vehicle, the vehicle receives the request signal from the remote controller, stores the request signal, and processes the request signal after the close operation is completed.

With the above arrangement, when a request signal is issued from the remote controller even during the close operation, the vehicle receives the request signal from the remote controller, the request signal is stored, and the door is operated by the closer operation. Since the processing of the request signal is performed after the fully closed state, the request processing from the remote controller can be reliably performed even when the closer is operating.

In this case, even when the remote control is operated while leaving the vehicle without noticing that the door is in the half-door state, the request signal from the remote control is received by the vehicle and the close operation is performed. After the door is fully closed, the door can be securely locked or unlocked in response to a request from the remote control,
The anti-theft property is improved.

Further, if the door is opened during the closing operation after the request signal is issued from the remote controller, the storage of the request signal from the remote controller can be cleared by the user. Can be operated as intended.

[0013]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a system configuration diagram of a door lock control device 1 according to the present invention. In this figure, a control device (also called a wireless receiver) 2 mounted on a vehicle 2
In the case of 0, a 12V power supply is connected from the battery 16, and a constant voltage (Vcc: 5V) is supplied from the power supply circuit 21. An ignition switch (IG SW) 4 for detecting an ignition state is provided in the control device 20.
And an unlock warning switch 15 for detecting whether a vehicle key (not shown) is inserted into the key cylinder or removed from the key cylinder, and provided inside the door 11 to lock the door lock. Alternatively, a door control switch 17 for issuing a request for unlocking is connected. The ignition switch 4 is open when the ignition is off and closed when the ignition is on. The unlock warning switch 15 is turned off when the vehicle key is removed from the key cylinder, and turned on when the vehicle key is inserted into the key cylinder.

The internal configuration of the control device 20 is
23 for receiving a signal (radio wave) from the remote controller, a detection circuit 22 for detecting a signal from the remote controller 10, an ignition switch 4, and an unlock warning switch 1.
Input interface (I
/ F) 25, output interface (I / F) for outputting lock and unlock signals to the actuator 19
26, states of the switches 4 and 15 and the remote controller 1
In response to a request signal input from 0, a CPU 27 that controls the operating device 19 by receiving a signal from the operating device 19 or a closer 30 described later, stores a unique identification code (also referred to as an ID code), and locks the door. A ROM 24 storing a program for controlling the opening and closing of the ROM.

On the other hand, the remote controller 10 is a small device to be carried by a user (particularly, a driver).
, An identification code and an unlocking code (lock request or unlock request).

The remote control 10 is provided with a button-shaped lock switch 10a and an unlock switch 10b on its surface, and outputs of the switches 10a and 10b are input to a CPU 40 inside the remote control. An antenna 10e that modulates and transmits a unique identification code preset for the user to the control device 20 inside the remote control.
Is connected to the CPU 10c via the transmitter 10d, and transmits an unlock code together with an identification code unique to the remote controller to the antenna 1
From 0e, it is emitted to the control device 20 attached to the vehicle side.

Next, the door closer 30 will be described. The door closer 30 is provided integrally with a closer mechanism CLZ in a door lock assembly shown in FIG. When the door 11 is set to the half door state, a position detection switch (motor position switch 38, latch switches 42, 43, pole switch 41, handle switch 44, etc.) incorporated in the closer mechanism CLZ detects the state of the half latch of the latch. Then, an output is made to one of the closer relays 34, 35. This allows the closer relay 34,
The closer motor 37 is rotated forward or backward by the current supplied to 35, and the latch and the pawl are brought into a fully locked state (fully closed state).

FIG. 5 shows the basic operation of the closer. When the door 11 is opened, the closer relay 3
4 turns on. Thereafter, when the door 11 is closed to the half-door state, the pole switch 41 changes from off to on (FIG. 4).
In the half latch state where the half latch switch 42 is turned off, the pole switch 41 is turned off.
Changes from on to off, and the closer motor 37 starts operating (closer operation). When the closer is actuated, the door 11 is fully closed within a predetermined time (about 3 seconds). From this state, the pole switch 41 is turned on from off, and then the full latch switch 43 is turned on to enter the full latch state. Eventually, the pole switch 41 turns off from on and the closer relay 34 turns off.

That is, when the door 11 is brought into the half-door state in the closer operation, the door 11 is automatically closed from the half-door state to the fully-closed state by the driving force of the closer motor 37.

FIG. 1 shows only a case where the closer 30 is applied to one door 11, and hereinafter, a description will be given of an arrangement provided for one door 11, but a closer provided on a vehicle door will be described. The number of the 30s is not limited, and here, it is assumed that four sets of the closers 30 are provided at four places of a driver seat, a passenger seat, and left and right rear seats. Since the structure and operation of the closer 30 are the same as those described above, individual description will be omitted.

The control device 20 includes four sets of the closers 3 of the vehicle.
0 is provided in the side cowl of the passenger seat in the passenger compartment, and a door open signal and a door fully closed signal from four sets of closers 30 are input. The closer 30 is controlled by a closer controller 39 and the battery 3
+ B (12V) power supply is connected to the power supply circuit 33, and the power supply circuit 33 always supplies a constant voltage. Signals from a pole switch 41 for detecting a door state, half / full latch switches 42 and 43, a handle switch 44, and a motor position switch 38 are connected to the closer controller 39. These outputs are sent to the CPU 31 via an input interface 36. Has been entered. The above switches 41, 42, 43, 44, 3
Reference numeral 8 is provided integrally with the door lock assembly 40 shown in FIG. 3 having the closer mechanism CLZ.

The door lock assembly 40 includes a door lock mechanism DLK including the operating device 19 and a closer mechanism CLZ. The door lock mechanism DLK performs a normal door lock operation, and the closer mechanism CLZ transmits the power of the closer motor 37 to the latch lever, and the latch center shaft 55
Is rotated, and the door 11 is changed from the half door state to the fully closed state.

Next, position detecting switches 41, 42, 43, 44, 38 provided on the door lock assembly 40 are provided.
Will be described.

The motor position switch 38 is attached to the closer motor 37, and detects whether the closer motor 37 is at the original position by a cam 51 provided on the motor shaft 56 and having a notch in a part thereof.

The half / full latch switches 42 and 43 are mounted in the door lock mechanism, and detect the state of the half latch or the full latch of the latch 52 of the closer 30. The pole switch 41 is a door lock mechanism DLK.
To detect the position of the pole 53. Further, the handle switch 44 is attached to the switch base of the door lock mechanism DLK,
It is linked to the inside or outside handle 2 and detects whether the inside or outside handle has been operated. The switching state transition diagrams of the switches 38, 41, 42, and 43 have output forms shown in FIGS. 4A and 4B.

Such a half / full latch switch 4
Based on the signals from the pole switches 2 and 43 and the pole switch 41, one of the closer relays 34 and 35 is energized to drive the closer motor 37. In other words, the closer motor 37 is driven by energizing one of the closer relays 34 and 35, and the state of each position detection switch is changed according to the drive state.

Regarding the operation, the condition for starting the normal rotation operation of the closer motor 37 is that the closer switch 34 is turned on, the pole switch 41 changes from on to off in the state of the half door and the half latch 42, and then turns on. The operation is started. When the operation is started, a full latch state is established, and the pole switch 41 is turned on from an off state.

The operation is started when the condition for starting the reverse rotation operation (energizing the closer relay 35) changes from ON to OFF of the pole switch 41, and thereafter, when the motor position switch 38 is turned OFF, the closer relay 35 is turned off.
Is terminated, the reverse rotation operation ends.

Next, the processing of the remote controller 10 capable of remote control will be described with reference to FIG. In the process of the remote controller 10, in step S1, the lock switch 10a
Is pressed and turned on by the user (operated)
Is checked. When the lock switch 10a is operated, in step S2, a lock code (1 bit) indicating a lock request is added to the identification code (16 bits) unique to the remote controller.
Bit) and transmits the result to the vehicle side, and then proceeds to step S1.
Return to

On the other hand, if the lock switch 10a has not been operated, it is checked whether the unlock switch 10b has been operated next. If the unlock switch 10b is not operated, the process returns to step S1, and waits for a state (trigger) in which the buttons of the lock switch 10a and the unlock switch 10b are operated (trigger). Then, the same processing from step S1 is repeated. 10b
Is operated, the unlock code (1 bit) indicating the unlock request is added to the identification code in step S4, and after transmission, the buttons of the lock switch 10a and the unlock switch 10b are operated in the same manner. After waiting for the trigger, the same processing from step S1 is repeated.

The transmission information from the remote controller 10 includes a parity bit for detecting a communication error on the receiving side, a start bit for starting communication, a stop bit for ending communication, and the like. Take
The code and the number of bits at the time of transmission are not limited to these.

Next, the processing of the control device 20 will be described with reference to FIG.
This will be described with reference to FIG. Here, only one set of closer 3
Although the processing is started from 0, the closer 30 is actually provided for each door (driver's seat door, passenger seat door, rear right door, rear left door).
, And a door open signal and a door fully closed signal from each closer 30 are input through two common lines.

When the battery 3 is connected and the power (12 V) is supplied in step S11, the control device 20 first performs an initial process of the system. In this initial processing, after checking the memory provided in the CPU, initial values required for this processing are set, and it is checked whether the system normally operates. In step S2, a receiving process from the remote controller 10 is performed. In the receiving process, since the identification code and the locking / unlocking code are sent from the remote control 10, the received signal is demodulated and separated, and the identification code unique to the remote control and the reception information as to whether the locking or unlocking request is issued in the CPU. Store in memory.
In this identification code, it is checked whether or not the identification code of the remote controller 10 registered on the vehicle side matches the received identification code. Next, after performing the wireless processing shown in FIG. 8 in response to the vehicle information and the request from the remote controller in step S13, the process returns to step S12.
Repeat the same process.

FIG. 8 shows the wireless processing in step S13. In step S101 of the wireless processing, it is first checked whether the identification code registered on the vehicle side matches the identification code sent from the remote controller 10. Here, if the two identification codes do not match, this process is terminated. However, if the identification codes match, the process proceeds to step S102 according to the state of the unlock warning switch 15 provided on the key cylinder. It is checked whether the vehicle key is inserted into the key cylinder (is in the ON state). If the vehicle key is not in the key cylinder (it is in the off state), this process ends. If the vehicle key is stuck in the key cylinder, step S103 is executed. Step S103
Then, it is checked whether the door 11 is open. The determination of the door open state is made by determining whether the half-latch switch 42 is on or the switches 41 and 4 from the door open state to the half-door state (transition state A) as shown in FIG.
The determination is made based on whether the switch outputs 2 and 43 have shifted. Here, if the door is in the open state, the process is terminated. If the door is not in the open state, it is checked in step S104 whether a locking instruction has been issued. Whether the locking instruction has been made can be determined by the locking code transmitted from the remote controller 10 (or whether the locking bit is set). If the locking instruction has not been made, the lock flag FL is determined in step S106.
1 is cleared and the unlock flag FL2 is set.
On the other hand, in step S104, the locking instruction is
If the lock flag is set to 0 (there is a lock request), the lock flag FL1 is set, and the unlock flag FL2 is set.
Is cleared, and the routine goes to Step S107.

Next, at step S107, the door 11
Is checked to see if it is fully closed. Door 11 is fully closed (half latch switch 42 is off, full latch switch 43 is on, pole switch 4
If the door 11 is not in the fully closed state, step S108 is executed.
Then, in step S114, it is checked whether the outside or inside handle operation is performed according to the state of the handle switch 44. Here, if there is a handle operation, the process proceeds to step S116, but if there is no handle operation (the door is not to be opened), it is next checked in step S115 whether the door is open. If the door is open (the half latch switch 42 is on, the full latch switch 43 is off, and the pole switch 41 is off), the process proceeds to step S116. If the door is not open, the process returns to step S107. That is, steps S114 and S11
In 5, the handle operation is performed, and the intention of the user to actually open the door 11 is determined by the handle switch 4.
In order to be able to reliably detect the failure even when the failure occurs, the detection is performed by two systems.

On the other hand, if the door is fully closed (the half latch switch 42 is off, the full latch switch 43 is on, and the pole switch 41 is off) in step S107, the lock flag FL1 is set in step S108, and the unlock flag is set. It is checked whether FL2 has been cleared (condition 1). Here, if the above condition 1 is satisfied, a lock signal (a low potential state) is output to the actuator 19 in step S109, and the door lock motor 20 is driven to lock the door lock. After performing the lock output for setting the state, step S1
Move to 12. On the other hand, if the condition 1 is not satisfied, in step S110, it is checked whether the lock flag FL1 is cleared and the unlock flag FL2 is set (condition 2). Here, the above condition 2
If the condition 2 is not satisfied, the process proceeds to step S116. If the condition 2 is satisfied, an unlock request is issued in step S111, and an unlock signal is output in step S111. To)
And the door lock motor 20 is driven to the unlock side to perform an unlock output for putting the door lock in an unlocked state.

Thereafter, in step S112, the process waits for a predetermined time (0.2 sec). In step S113, the relay 18 is de-energized, and the door lock motor 20 is stopped. In step S116, the door lock flag F
The operation of clearing L1 and unlock flag FL2 and ending this processing is performed.

In this case, even if the user operates the remote controller 10 while leaving the vehicle without noticing that the door 11 is in the half-door state as in the prior art, even if the remote controller 10 is locked or unlocked. Since the signal is received on the vehicle side and the door 11 can be completely locked or unlocked in response to a request from the remote controller 10 after the door 11 is fully closed by the closer operation, theft prevention performance is improved. Is improved.

A request signal for locking or unlocking the door 11 is issued by a switch operation from the remote control 10, and the outside handle 2 or the inside handle is operated during the closing operation to operate the door 1.
When 1 is released, the storage of the signal from the remote controller 10 (the lock flag FL1 and the unlock flag FL2) is both cleared, so that the operation intended by the user can be reliably handled.

The above-described door lock control device is also applicable to a wireless door lock control device that transmits and receives an identification code between the vehicle and the remote controller when the driver gets off the vehicle.

[0042]

According to the present invention, a remote control carried by a user for remotely controlling a lock and unlock request of a vehicle door, a door state detection means provided on the vehicle side for detecting an open / closed state of the door, and a door state detection Means for closing the door when the door is in the half-door state by means of the door lock control device, when the close operation is performed and a request signal is issued from the remote controller, the vehicle side receives the request signal from the remote controller. By receiving the request signal, storing the request signal and processing the request signal after the close operation is completed, even if the request signal is issued from the remote control even during the close operation, the remote control on the vehicle side Received the request signal from, the request signal is stored and the request signal is processed after the door is fully closed by the closer operation. Closer is even during operation, it is possible to perform request processing from the remote controller.

In this case, even when the user operates the remote controller while leaving the vehicle without noticing that the door is in the half-door state, the vehicle receives the request signal from the remote controller and operates the closer. Thus, the door can be reliably locked or unlocked in response to a request from the remote controller after the door is fully closed, thereby improving anti-theft properties.

If the door is opened during the closing operation after the request signal is issued from the remote controller, the storage of the request signal from the remote controller can be cleared by the user. Can respond to the intended operation.
