[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a keyless entry system used for keys of automobiles and houses.

[0002]

2. Description of the Related Art In recent years, a keyless entry system has been developed that locks or unlocks a key by transmitting and receiving electromagnetic waves.
For example, it is widely used as a key for automobiles and houses. In such a keyless entry system, when a remote controller key is operated and a predetermined signal is transmitted and output from the remote controller key, the receiver receives the signal and the receiver outputs a key signal to perform a keying or key releasing operation. The lock mechanism is configured to perform. More specifically, in general, a remote control key modulates a predetermined secret code and transmits and outputs it as an electromagnetic wave such as infrared rays or radio waves, and a receiver detects the received electromagnetic wave to take out the secret code, and the secret code thus taken out. In response to the output from the receiver, the lock mechanism unit has a structure for performing a keying operation or a key releasing operation in accordance with the output from the receiver.

[0003]

In such a keyless entry system, since the lock mechanism is remotely operated by the remote control key to perform keying or unlocking, the keying or unlocking is surely performed after the remote controller key is operated. Sometimes it's hard to tell if you've been locked. For example, it may be difficult to hear the sound generated when keying or unlocking in a place where noise is loud, or the keying or unlocking operation may not be visually recognizable depending on the position of the key driven by the lock mechanism. I have something to do. For this reason, when operating the remote control key, it is difficult to obtain a certain sense of operation, and there is a problem that an operational uneasiness tends to occur.

[0004] In addition, in the installation object on which the receiver is installed, inconvenient results may be brought about when keying is performed. For example, in the case where the receiver installation target is an automobile, the headlight may be turned on or the window may be opened when the key is applied. Further, in the case where the installation object of the receiver is a house, it is inconvenient if, for example, the gas range is ignited or the house alarm device is turned off when the key is applied.

[0005]

However, the receiver further includes a receiving unit that receives the failure elimination signal and a driving unit that outputs a predetermined driving signal when the receiving unit receives the obstacle elimination signal.

[0008]

According to the present invention, when the operation switch is turned on at the remote control key side, the personal identification code signal is transmitted and output as an electromagnetic wave from the remote control key, and the receiver receiving the personal identification code signal outputs the key signal. As a result, the lock mechanism unit performs a keying operation or a key releasing operation. At this time, the operation switch of the remote control key is driven by the switch light emitting means to perform light emission display. Further, when the operation state confirmation means confirms the operation of the lock mechanism section, the receiver transmits the confirmation signal as an electromagnetic wave by the confirmation signal transmission output means, and the confirmation display section is displayed on the remote control key when the confirmation signal is received by the reception section. It emits light by being driven by the display light emitting means. In other words, with the remote control key, the operation switch emits light when it is turned on, and when the operation of the lock mechanism section is confirmed on the receiver side, the confirmation display section that is integrated with the operation switch emits light and the operator is informed of the operation. It brings a feeling.

According to the second aspect of the present invention, when the operation switch is turned on on the remote control key side, the personal identification code signal is transmitted and output as an electromagnetic wave from the remote control key, and the receiver receiving the personal identification code signal outputs the key signal. As a result, the lock mechanism unit performs a keying operation or a key releasing operation. At this time, the receiver that has received the keying command outputs the warning signal as an electromagnetic wave by the warning signal transmission output means when the failure detection means detects the inconvenience associated with the keying in the installation object of the receiver, and receives this warning signal. With the remote control key received by the unit, the warning signal is displayed and output by the display means. As a result, when the receiver installation target is inconvenient due to keying, the operator who has instructed the keying operation by turning on the operation switch is warned of the inconvenience, and safety is improved. In this case, according to the third aspect of the present invention, when the warning signal is displayed and output, the warning display section which also functions as an operation switch emits a light emission display. The failure elimination signal is transmitted and output as an electromagnetic wave by the output means. Then, the receiver that has received the failure elimination signal at the receiving unit outputs a predetermined drive signal by the drive means, and solves the inconvenience in the object on which the receiver is installed.

In such a configuration, the remote control key 1
When the operation switch 5 is turned on, the lock mechanism 3 is remotely operated to lock or unlock the door of the automobile. The processing at this time will be described based on the flowcharts of FIGS. 5 and 6. FIG. 5 is a flowchart on the remote controller key 1 side, and FIG. 6 is a flowchart on the receiver 2 and lock mechanism section 3 side.

First, in FIG. 5, when the operation switches 5 and 35 on the side of the remote controller key 1 are turned on, power is supplied from the battery 4 to each part in step S1 and is incorporated in the operation switches 5 and 35 turned on in step S2. The LED 36 is driven, and the operation switches 5 and 35 emit green light. This state is illustrated in FIG. Here, the switch light emitting means is executed. In the subsequent step S3, when the operation switch 5 is turned on, the RAM 8 is transmitted through the transmission output device 9.
The personal identification code stored in the personal identification code area 8a is converted into a personal identification code signal, and when the operation switch 35 is turned on, a predetermined code signal is converted into a failure elimination signal,
Each is transmitted and output as an electromagnetic wave.

When the personal identification code signal or fault elimination signal transmitted and output in this way is received by the receiver 16 of the receiver 2, the receiver 2 proceeds to step S2 as shown in FIG.
1. The personal identification code signal received in 1 is compared with the personal identification code stored in the personal identification code area 15a of the RAM 15, or the received failure elimination signal is compared with the corresponding code stored in the RAM 15, and in step S22, Only when they match, a drive signal is output to the corresponding actuator 20 or the corresponding motor 21 of the lock mechanism unit 3 in step S22, and the drive signal is output to the CPU 13 on the receiver 2 side. As a result, the actuator 20 or the motor 21 is driven so that the lock mechanism unit 3 performs a desired operation, or the CPU 13 issues a desired operation. For example, when the door lock 5a in the operation switch 5 is turned on, the door lock actuator 20a is driven to lock the door, and when the window 35d in the operation switch 35 is turned on, the window motor 21a is driven. When the window is closed and the headlight 35a in the operation switch 35 is turned on, a command to turn off the headlight (not shown) is transmitted from the CPU 13 to the microcomputer on the vehicle side (not shown), and the headlight is turned off. .

[Operating State Confirming Means] In the receiver 2, the actuator 2 is operated in step S23 subsequent to step S22.
The operating state such as 0 is detected by the sensors 37, 38, 39, 40, and the operating state is confirmed. Here, the operation state confirmation means is executed.

[Confirmation Signal Transmission / Output Means] Then, when the operation of the actuator 20 or the like is confirmed, step S
At 24, an operation confirmation signal is transmitted and output as an electromagnetic wave from the transmission output device 17. Further, when it is confirmed that the actuator 20 or the like is inoperative, an inactivation confirmation signal is transmitted and output as an electromagnetic wave from the transmission output device 17 in step S25, and the process ends. Here, the confirmation signal transmission output means is executed.

[Display Light Emitting Means] As shown in FIG. 5, on the remote controller key 1 side, the operation confirmation signal among the confirmation signals transmitted and output from the receiver 2 is received by the receiver 10 in step S4 following step S3. Then, step S5
The LED 36 built in the confirmation display unit 33 is driven by
The confirmation display unit 33 emits blue light. This state is shown in Figure 1.
An example is shown in (b). Here, the display light emitting means is executed.

In other words, in the apparatus of this embodiment, the operation switch 5 emits light when it is turned on (see FIG. 1 (a)), and when the operation of the lock mechanism portion 3 is confirmed, the operation switch 5 is arranged integrally with the operation switch 5. The confirmed display portion 33 emits light (FIG. 1 (b)).
(See), you can get a certain sense of operation. This can give the operator a sense of security in operation. Moreover, since the operation switch 5 and the confirmation display unit 33 are integrally arranged, the relation between the operation switch 5 being turned on and the light emission display of the confirmation display unit 33 is easy to intuitively understand.

On the other hand, when the operation confirmation signal is not received by the receiver 10 in step S4, it is checked whether or not the inactivation confirmation signal is received by the receiver 10 in step S6. If it is determined that the non-operation confirmation signal is not received, the time-up is confirmed in step S7, and if the time-up has not been received, the process returns to step S4. If the time is up, the power supply stop process is executed in step S8, and then the process ends. When it is determined in step S6 that the non-operation confirmation signal has been received, a notification to that effect is issued in step S9, and then the power supply process in step S8 is performed and the process ends. The notification is performed by outputting the artificial voice synthesized by the voice synthesizer 11 from the speaker 12 under the control of the CPU 6. In addition,
Notification of such corresponding information is also made in step S10 following step S5. This step S1
The notification of 0 is a notification of operation confirmation.

[Fault Detection Means] Next, as shown in FIG. 6, in the receiver 2, the code signal received in step S26 after the transmission of the operation confirmation signal in step S24 described above is the code indicating the keying of the door. Whether it was a signal C
It is determined by the arithmetic processing of PU13. If it is determined that the code signal does not mean that the door is keyed, the process is terminated, whereas if it is determined that the code signal means that the door is keyed, the door is a half-door in step S27. After it is detected that there is no window, the window is not opened in step S28, the headlight is not turned on in step S29, or the ignition is not turned on in step S30, the process ends. These detections include a sensor 39 for monitoring the operating state of the window driven by the window motor 21a, a sensor 40 for monitoring the open / closed state of the door driven by the door opening / closing motor 21b, and the CPU 13 for temporarily storing various states. And R
This is done based on the data stored in the area of the AM 15. Here, the failure detection means is executed.

[Warning Signal Transmission / Output Means] Step S27
In step S30, when each inconvenient state, for example, the lighting of the half door or the headlight is detected, step S31 corresponding to step S27, step S32 corresponding to step S28, step corresponding to step S29 In step S34 corresponding to S33 and step S30, the corresponding alarm signal is transmitted to the transmission output device 17
Is transmitted and output as electromagnetic waves. The warning signal transmission output means is executed here.

[Display Means] Next, as shown in FIG.
In the remote controller key 1, when the receiver 10 receives the warning signal transmitted and output from the receiver 2 in step S11 following step S10 described above, the LED 36 incorporated in the warning display unit 34 is driven in step S12 to display the warning display. The portion 34 emits red light. Then, the following step S13
Then, the LED 36 incorporated in the operation switch 35 of the item corresponding to the received warning signal is driven, and the operation switch 35 emits orange light. For example, when the warning signal is a code signal meaning "window open", the window 35d in the operation switch 35 emits light. This state is illustrated in FIG. The display means is executed here.

In this way, when the door key is instructed from the remote control key 1, an inconvenient state is detected by the receiver 2 when the door is keyed and the vehicle leaves the vehicle, and a warning is displayed on the remote control key 1. Therefore, it is possible to improve safety when using the keyless entry system.

Here, step S following step S13
At 14, a voice notification corresponding to the warning signal is given. For example, "the window is open". If no warning signal is received in step S11, step S15
The time-up monitoring process is repeated.

[Fault Resolving Signal Transmission / Output Means] Next, in step S16 subsequent to step S14, it is determined whether or not the operating switch 35 that is emitting light is turned on until the time-up monitored in step S17.
When it is determined that the operation switch 35 has been turned on, in step S18, the failure output signal, which is a predetermined code signal, is transmitted and output from the transmission output device 9 of the remote controller key 1 as an electromagnetic wave, and after the power feeding process in step S8. The process ends. The fault elimination signal here is a signal that means a command to drive the window motor 21a on the receiver 2 side to execute the process of closing the window, for example, when the operated operation switch 35 is the window 35d. Here, the failure elimination signal transmission output means is executed.

[Driving Means] When the fault elimination signal is transmitted and output from the remote controller key 1 in this way, the receiver 2 executes the processing after receiving the code signal shown in FIG.
That is, when it is determined that the codes match in step S21, the drive signal for the corresponding motor 21 is output in step S22, and the desired operation is executed. For example, if the signal to clear the obstacle is a signal that means "window closed",
A drive signal for closing the window is output to the window motor 21a. Here, the driving means is executed.

Therefore, if an inconvenient state occurs when the door is locked and the vehicle is separated from the automobile, the operation which the operator originally has to do is to unlock the door again to correct the inconvenience. Is automatically executed to simplify the work.

A second embodiment of the present invention will be described with reference to FIGS. 7 and 8. The same parts as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted. In this embodiment, the emission color of the operation switch 5 can be switched by a command from the CPU 6. As a specific configuration for that purpose, the structure is such that two LEDs 36 each having a transparent colored cover of a different color are built in one operation switch 5. Then, as the process executed by the CPU 6, following the light emission process of the confirmation display unit 33 in step S5, in step S19, the color B of the light emission of the operation switch 5 at this time is changed to the operation switch 5 in step S2. It is configured to switch from the color A, which is the light emission color, and emit different colors.

In such a structure, the operation switch 5 emits the color A by the closing operation (step S2, FIG. 8).
(See (a)), and when the operation of the lock mechanism unit 3 and the like is confirmed (Step S4), the confirmation display unit 33 disposed integrally with the operation switch 5 emits light (Step S5, see FIG. 1B). The emission color of the operation switch 5 changes to B color (step S19, see FIG. 1C).

In this embodiment, the operation switch 5 and the confirmation display section are integrally formed, and the operation switch 5 also serves as the confirmation display section. Therefore, in the implementation, the confirmation display section 33 is omitted. Is also good.
