Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a vehicle lock control system that enables wireless locking and unlocking of vehicle locks. .

(Background of the Invention) The present applicant previously proposed (-Radio Key System) in Japanese Patent Application No. 57-132118 (unpublished).

As shown in Fig. 1, this radio key system (hereinafter referred to as a vehicle locking system) consists of a transmitter 11 carried by the driver, and a vehicle side mount 2 installed on the vehicle side. These are loop antenna 3 and loop antenna 1.
Connected via 0a and 10b. FIG. 2 shows a specific embodiment.

In the transmitter R1, each circuit together with the loop antenna 3 is incorporated into a card-shaped case the size of a business card, and can be easily accommodated in a driver's pocket, handbag, or the like.

The vehicle body side device 2 includes the loop antenna 10a installed on the side of a rear opening/closing body such as a trunk lid or hatch gate, the loop antenna 10b installed on the side of a side opening/closing body such as a door, and the loop antenna 10b installed on the side of a side opening/closing body such as a trunk lid or door. lock t
Il! It is comprised of an actuator 17 that performs unlocking, and a control device 118 that controls the actuator 17 by receiving signals received from the loop antennas 10a and 10b.

FIG. 2 shows a case where the present invention is applied to a four-door type passenger car. In the figure, a pair of loop antennas 10a are disposed inside the rear panel 19, and these are connected to the control device 18.
connected to. On the driver's side, rearview mirror 2
0 and driver's side sea I/21 above loop anti-no 1
0b are arranged, and similarly these form a pair to control circuit 1.
Connected to 8. Further, switches 12 are provided on the rear end side of the trunk lid 22 and near the door handles of the driver's seat door and rear door, respectively.

In such a configuration, assume that a driver or the like carrying the card-type transmitter 1 manually operates the switch 12 in order to open the trunk lid 22. Then, the vehicle body side device 2
Now, the transmission request signal generation circuit 1 in the control device @18
1 is activated and transmits a riffist signal from the loop antenna 10a for a certain period of time.

The card type transmitter 1 is always powered on, and each internal circuit is on standby. Therefore, the signal transmitted from the loop antenna 10a to the loop antenna 3 by electromagnetic induction is taken into the internal circuit. First, the lift signal detection circuit 7 detects that the request signal is transmitted from the vehicle body device 2, and activates the code signal generation circuit 8. When the code signal generation circuit 8 is activated, it outputs a vehicle-specific code signal (a different code is set for each vehicle) that has been stored in the code storage circuit 9 in advance. Then, in the modulation circuit 5, the carrier signal supplied from the carrier oscillation circuit 6 is modulated by the code signal, and the output circuit 4.
Transmit via loop antenna 3.

Then, on the vehicle side, the above card type transmission Il! 1
The unique code signal transmitted from 1 is received by the loop antenna 10a, and the received unique code signal is sent to the code matching circuit 14 via the receiving/demodulating circuit 13.
supplied to

The code matching circuit 14 determines whether or not the vehicle-specific code signal registered in advance in the code storage circuit 15 matches the received code signal.

Then, the actuator drive circuit 16 is driven only when both code signals match.

When the actuator drive circuit 16 is driven, the actuator 1 unlocks and locks the trunk lid 22.
7 is driven, and the trunk lid 22 is unlocked. Next, when the trunk lid 22 is closed after taking out the luggage from the trunk, the actuator drive circuit 16 is driven in response to this, and the actuator 1
7, the trunk lid 22 is automatically locked.

Regarding the door side, the door side actuator 17
is configured to reverse the state of the lock in response to the operation of the switch 12. That is, when the switch 12 is operated, if the lock is locked, the lock is unlocked, and if the lock is unlocked, the lock is locked.

In this way, this vehicle locking control device opens and closes the trunk lid, doors, etc. only when the code signal on the card type transmitter 1 side and the code signal registered on the vehicle body side device 2 match. It is configured to unlock and lock the lock on the body. Therefore, even if a person who does not possess the card-type transmission m1 attempts to unlock the lock, the lock will not be unlocked. Further, even if a person carrying a card type transmitter 1 with a different code signal attempts to unlock the lock, the lock will not be unlocked. As a result, the card-type transmission Wa11i has the same security performance as a conventional mechanical key.

Furthermore, since the card-type transmitter 1 can be used while being stored in a pocket or bag, it eliminates the need to take out the key every time the lock is unlocked or locked, unlike conventional mechanical keys. becomes.

By the way, as we continued to conduct further research on such vehicle locking control devices, we assumed the following situation, especially in the locking control of rear opening/closing bodies such as trunk lids and hatch gates. In other words, when you open the trunk lid to take out luggage, or when you open the hatch gate to take out luggage from the passenger compartment, the bag containing the card-type transmitter 1 must be placed in the trunk or inside the vehicle. A situation may arise in which the trunk lid or hatch gate is closed while the vehicle is left in the vehicle.

In such a case, the trunk lid and hatch gate 1 are automatically locked, so the driver or the like will not be able to take out the card-type transmitter 1 if it is left in the trunk.

Also, in a hatchgate type vehicle, if the door is unlocked, you can take it out from the driver's seat, but if the door is locked, it is the same as leaving it in the trunk.

Therefore, as a result of carrying out development while taking these matters into consideration, the present invention was achieved.

(Object 1 of the Invention) The purpose of this invention is to prevent the above-mentioned card-type transmitter IJ1 from being left behind in a vehicle interior that is opened and closed by a rear opening/closing member such as a trunk lid door. .

(Structure of the invention) The configuration of this invention will be explained below with reference to FIG.

The receiving means 101 receives a predetermined signal wirelessly transmitted from the portable transmitter 111100 using an antenna provided on each opening/closing body side of the vehicle.

Unique signal matching means 102 determines whether the signal received via the antenna matches a unique signal preset on the vehicle body side.

The switch 103 outputs a signal to start controlling the locking/unlocking operation of a lock at a predetermined portion of the vehicle body near each opening/closing body in response to manual operation.

The actuator driving means 104 drives the actuator 105 to lock and unlock the lock when the switch is operated and it is determined that the unique signals match.

Particularly, in the device of the present invention, in the receiving means 101, the antenna installed on the side of the contact portion 6m of the vehicle is replaced by the indoor antenna 10 installed in the vehicle interior that is opened and closed by the rear opening/closing body.
1a and an outdoor antenna 101b provided outside the vehicle interior, and is configured to enable communication with the indoor antenna 101a when the portable transmitter 1100 is left behind in the single compartment.

The key switch 59 is a switch for detecting whether or not a key is inserted into the key cylinder of an ignition key switch in the driver's cab, and is turned on when the key is inserted into the key cylinder.

The lock knob switch 60 is a switch that is turned on when the door lock knob provided on the inner surface of the door on the driver's seat side is pushed in to lock the door.

The lock state detection switch 61 is a switch that detects the state of the door lock mechanism, and is turned OFF when the door lock mechanism is in the locked state, and turned ON when the door lock mechanism is in the unlocked state.

The power start detection circuit 54 includes each of the switches 57 to 6.
If any one of 3 is turned on (however, switches 57 and 61 are turned on.

It is driven for a predetermined period of time (when switching OFF), and power is supplied to each circuit from the power leap line 55. Also,
When the power hold signal S3 supplied from the output port 05 of the CP LJ 53 arrives, the O of each of the switches is
The configuration is such that the power supply is continued regardless of the N operation, and the power supply is stopped when the CPU 53 enters the standby state.

In this way, in the device of this embodiment, each switch 57
Until any one of the 63 circuits is operated, the power supply to each circuit is stopped, except for the minimum number of power supplies, thereby minimizing the consumption of the in-vehicle battery. The structure is designed to reduce this.

The relay 65 is driven by the 1 to rank unlock signal S8 being output from the output capo I-08 of the CI U 53 and the transistor 1"rl being turned on, and is driven by the trunk lock unlocking solenoid (not shown). ) to unlock the trunk. Note that when the trunk lid is closed, the trunk lock is automatically locked.

The relay 67 rotates the motor in the forward direction to unlock the door.

Furthermore, a unique code is input from the input port 112 of the CPU 53 via a multiplexer 69.

In the unique code plug 70, a code signal unique to the vehicle is registered in advance.

Such a unique code plug 70 is a multi-break cable 69.
By being inserted into the connector of the multiplexer, unique code data is supplied to the CPU 53 from the multiplexer.

The CPU 53 senses the state of each input port and outputs a control signal to the corresponding output port.

For example, when the activation switch 62 on the driver's seat side is operated,

46b, and a pair of antennas 41e, 41 on the driver's seat side.
Make f active.

Next, referring to FIG. 6, the locking control operation of the one-heran lid according to the first embodiment will be explained. FIG. 6 (A> is the microphone 1 computer 3 in the card type transmitter 11130)
FIG. 6B is a flowchart showing the trunk lid locking control operation among the control operations of the CPU 53.

As shown in FIG. 2, when a driver etc.
Approach the trunk lid with the , and press the activation switch 63.
(step (10)), the CPU 53 operates the input port I. is LOW level (hereinafter referred to as “°L”)
In response to this, control signals Pr are sent from output ports 1 to 03.
S+ is output, and the antenna pair 418, 4 on the trunk side
1b and 410.41d are activated. at the same time,
In step (11), the drive signal S5 and the switching signal S4 are output from the output port 01.02. Then, the carrier wave generated from the oscillator 50 is subjected to predetermined modulation in the modulator 49 to form a request signal, and this refresh first signal is transmitted to the selector switch 48. Antenna pairs 41a within and outside ranks 1 to 1 through a switching circuit 46a and a high frequency amplifier 45a
, 41b, 41c, and 41d, and transmits a request signal.

In this manner, when the request signal is transmitted, the card-type transmitter 1130 carried by the driver etc. proceeds to step (2) via step (1) and stores the memory 34 in advance.
Reads the vehicle-specific code signal (for example, 4-pilt - 4-digit serial data set by the combination of *0)u, +1111) stored in the . Next, in step (3), a pulse train signal corresponding to the read unique code data is output to the modulation circuit 35. As a result, a signal multiplied by the unique code signal is transmitted from the loop antenna 31 of the card type transmitter 30.

Then, on the vehicle side, in step 12, the code signal is received by a pair of antennas inside and outside the trunk.

In the next step (13), among the received unique code signals, the signal received by the loop antenna <ib, 4id is phase-shifted by 90 degrees by the 90 degree phase shifter 42, and After being combined with the signal received by the .41C, it is supplied to the detection/demodulator 52 via the switching circuit 46b, the changeover switch 48, and the high frequency amplifier 51. The code signal component in the carrier wave is extracted by this detector/demodulator 52, -C, CPU 53
is input to input port 11 of. The code signal input to input port 1 is temporarily stored in a predetermined register.

In the next steps (14) and (15)r, the unique code data set on the vehicle body side is read from the Multiplec+L 69, and it is compared with the received code data to determine if the two match. Let's do it.

In step (16), as a result of the above matching determination process, N
o If there is a mismatch, the trunk lock will not be unlocked. That is, in this case, the card type transmitter carried by the person who operated the activation switch 63 is
Something that is not compatible with this vehicle! In other words, the person operating the switch is not the owner of this vehicle.

On the other hand, if the result of the above determination process is YES (match), the process proceeds to step (17), where the trunk unlock signal S8 is output from the output J boat 08, and the transistor Tr+
is turned ON to operate the relay 65. This unlocks the trunk lock and allows the trunk lid to be opened.

When the driver or the like closes the trunk lid after taking out luggage from the trunk, the locking operation is automatically performed. At this time, if the transmitter 11130 is left behind in the trunk, the driver etc. must press the start switch 63 again.
All you have to do is operate.

In other words, if the start switch 63 is operated again, each routine from step (1) to step (17) will be executed again via the antenna pair 418.41b in the trunk, so that the trunk lid will not be closed at any time. I can do it.

Note that the harness wire for connecting the amps 41C and 41d outside the trunk to the case housing the control device should be wound several times inside the trunk before being connected to the control device. Since the winding portion acting as a loop ambulator, the need to separate the loop ambulators 41a, 411) in the trunk in the above embodiment is reduced to 1.1.This reduces the number of parts. It is possible to reduce the cost and reduce the cost.

Next, a second embodiment of the present invention will be described with reference to FIGS. 7 and 8. Note that, although the same applies to each of the following embodiments, the same parts as in FIGS. 4 to 6 are denoted by the same reference numerals, and the explanation thereof will be omitted.

In FIG. 7, this second embodiment (pull control device m
s or r Ha, CPtJ53 (7) Outh boat 0++
The changeover switch 81 is actuated by the changeover signal S output from the antenna pair 41a in the trunk.

41b and the antenna pair 410.41d outside the trunk are activated.

With this configuration, as shown in FIG. 8, after the driver or the like closes the trunk lid while leaving the card-type transmitter 30 in the trunk, the activation switch 63 can be turned off.
When operated, first, in step (11), a transmission request signal is sent out from the antenna pair 41C141d outside the trunk, but since the card type transmission 4g1130 is inside the trunk, a code signal is received in the next step (12). I can't. As a result, CPLI53 is output capo-1
- A switching signal S is output from 11, and the selector switch 81 is switched to the trunk antenna pair 418.41b side, and the trunk antenna pair 41a is switched.

41b to the active state. Then, in step (11), a transmission request signal is output again from the antenna pairs 418.41b in ranks 1 to 418. As a result, the code signal is received in step (12), and each routine from step (13) to step (17) is sequentially executed in the same manner, and the trunk lock is unlocked.

In this way, by switching the antinodes inside and outside the trunk, it is possible to detect whether the =1-do signal from the card type transmitter 30 is received from the inside or outside of the trunk. If the code signal is received at , it can be determined that the card type transmission 1130 has been left behind in the trunk.

Next, a third embodiment of the present invention is shown in FIG. 9j3 and FIG. 10.

In FIG. 9, in the control device M90 according to the third embodiment, the antenna pair 418, 41b inside the trunk and the antenna pair 41C, 41d outside the trunk are the same as those in the second embodiment, but newly added. A trunk lid switch 91 and an alarm drive circuit 92 are numbered.

The trunk lid switch 91 detects the open/closed state of the trunk lid.
It turns ON when it is in the 1 state, and turns OFF when the trunk lid is in the open state. This ON/OFF signal (a) is input to the input port 111 of the CPU 53 as a trunk lid open/close state detection signal.

CP LJ 53 "C has a lid switch flag F+ provided in a predetermined area of the RAM. When the trunk lid switch 91 is turned ON, the lid switch flag 1:1 is turned on, and when the switch 91 is turned OFF, the lid switch flag F + is set. F1 is reset.

The alarm drive circuit 92 is driven by an alarm signal S9 outputted from the output port 09 of the CPU 53, and sounds a horn or drives a buzzer.

In FIG. 10, after the trunk lid is unlocked in step (17), when it is detected in step (20) that the trunk lid is closed, step (
21), set the lid switch flag "1 to 1" and proceed to step (22).

In step (22), the selector switch 81 is activated to activate the pair of antennas 41a and 4.1b in the trunk.

As a result, the same routine as the routine from step (11) to step (16) is performed in the routine from step (23) to step (28).

And step (29) smell - C1 output capo - h 0
9 outputs an alarm signal QS9, and the alarm drive circuit 92 is not activated. This allows the card-type transmitter 3 to be installed in the trunk.
The driver who closes the trunk lid and leaves the vehicle with 0 left there will be notified that the card type transmission 1.30 has been left behind.

The trunk lid is then automatically unlocked using the slab (30).

This allows drivers, etc. to open the trunk lid and
Card type transmission [30] can be carried out from within the ranks without taking it out. At this time, the switch 91 detects that the 1-rank lid has been removed, so the lid switch flag [=1 is set to 1~, and the switch 71 is set to 1.
- It will be switched to the antenna pair 41c, 41d outside the rank.

Thereafter, the trunk lock will be unlocked only by operating the activation switch 63.

Finally, the fourth diagram of this invention is shown in Figure m11 L15 and Figure 12.
An example is shown below. In the control device 94 according to the fourth embodiment, the antenna pair 41a on the trunk side.

41b a3, 41G, 41d, and an alarm drive circuit 92 are provided in the same manner as in the third embodiment, but switches 95 and 96 are further provided.

;- The trunk lid switch 95 detects the opening/opening operation of the trunk lid.
It is turned on when the lid changes from "closed" to "1-", and turned off when the lid changes from "closed" to "open". In the CPLI 53, the trunk lid switch 9 corresponds to the operation of the trunk lid switch 95.
An I/rank lid flag F2 is provided in a predetermined area of the RAM, and is set in a predetermined area of the RAM.

The locked state detection switch 96 detects the state of the lock 11 of the lock mechanism, and is turned OFF when the lock mechanism is in the locked state, and turned ON when the lock mechanism is in the unlocked state.
becomes.

In FIG. 12, when the trunk lid is about to be closed after the trunk lid is unlocked in step (17) and 1~ rank lid is heard, step (17) is performed.
This is detected in step (35), and the rank grid flag F2 is set to 1- in step (36). Then, in step (37), the selector switch 71 is activated to activate the pair of antennas 41a and 41b inside the trunk. As a result, each routine from step (38) to step (43) is changed from step (11) to step (16).
The routine is the same as the routine leading up to .

If a match is detected in step (43), step (4)
/l) activates the alarm drive circuit 92, and the locked state of the locking mechanism is detected in step (45). Then, if the 1st lock mechanism is not in the locked state, the 1st actuator is activated in step (46), and the 1st to 1st lock mechanism is in the locked state.

In other words, in step (45) and step (46), the locking mechanism is set to the locked state when the 1st rank lid is closed, and when the driver etc. leaves the 1st rank lid closed, the locking mechanism becomes unable to be locked. do. As a result, the trunk lid is not locked even if the driver tries to close it, and the driver or the like will know that he or she has left the card-type transmitter 11130 in the trunk.

Thereafter, when the driver or the like opens the trunk lid and takes out the card type transmitter 30, the trunk lid flag F2 is reset in response to the opening of the trunk lid. As a result, the selector switch 81 is activated, and the pair of andenos 41c and 416 outside the trunk becomes active.Therefore, the driver 11 and others operate the activation switch 63 after taking out the card-type transmitter 11130 from the trunk. J: The door is now in a locked state.[The one-click mechanism can be unlocked, and]-If you tighten the lid, it will automatically become locked.

J3, in the third embodiment, the 1-rank lid is automatically unlocked and the trunk lid opens, and in the fourth embodiment, the trunk lid cannot be closed, which functions as a kind of alarm. I will do it. Therefore, the third. In the device of the fourth embodiment, the vI information drive circuit may be omitted.

(Effects of the Invention) As explained in detail above, in the vehicle locking control device of the present invention, antennas are arranged in tiers in the interior of the vehicle, which is closed by 1m by the rear opening/closing body, and in the exterior of the vehicle. Therefore, even if the card-type transmitter is left behind in the vehicle, it can be taken out, making it more convenient and improving performance.
