Returning to FIG. 1, the in-vehicle reception device 3 receives the transmission signal of the transmission device 2 via the antenna 35 as well as the first reception unit 32 that receives the transmission signal of the transmission device 2 via the antenna 34. 2 and a control unit 31 that outputs a control signal to the vehicle-side circuit 4 in response to transmission signals received by the first receiving unit 32 and the second receiving unit 33 serving as the receiving unit. .
The control unit 31 includes a door lock controller 41 and a headlight controller 42 of the vehicle side circuit 4.
Are connected to each of the emergency flashing indicator controller 44 and the horn drive unit 45,

In the present embodiment, the first receiving unit 32 and the second receiving unit 33 included in the in-vehicle receiving device 3 have different reception sensitivities. Specifically, the receiving sensitivity of the second receiving unit 33 is set to be higher than that of the first receiving unit 32.

FIG. 3 is a diagram showing a more detailed configuration of the first receiving unit 32 and the second receiving unit 33.
As shown in FIG. 3, the first receiver 32 and the second receiver 33 are both realized by the same circuit configuration.
In the first receiving unit 32 and the second receiving unit 33 shown in FIG. 3, the received signals received by the antennas 34 and 35 are amplified by a low noise amplifier (LNA) 301, and the mixer 30.
2 and the local oscillator 303 perform frequency conversion. The converted received signal is input to the demodulation circuit 305 through the band-pass filter (BPF) 304, demodulated by the demodulation circuit 305, input to the waveform shaping circuit 307 through the low frequency filter (LPF) 306, and the waveform shaping circuit 307. After the waveform is shaped by this, it is output to the control unit 31.

The first receiving unit 32 and the second receiving unit 33 configured as described above are NF (noise figure), LNA
By adjusting the gain at 301, the gains of the antennas 34 and 35, and the positions of the antennas 34 and 35, the reception sensitivity can be changed.
The reception sensitivity of the first reception unit 32 is set so that the transmission signal from the transmission device 2 can be received well, for example, at a distance of 10 m (meters) to 1 m or less, and the second reception unit 3
The reception sensitivity of 3 is set to a reception sensitivity capable of satisfactorily receiving a transmission signal of the transmission device 2 located at a longer distance, for example, a distance of about 10 m from a distance of 30 m or more.
In this case, for example, when the transmission device 2 is separated from the in-vehicle reception device 3 by 20 m or more, the transmission signal of the transmission device 2 is received only by the second reception unit 33. For example, when the transmission device 2 is located within 5 m from the in-vehicle reception device 3, the second reception unit 33 is saturated when receiving the transmission signal from the transmission device 2, and the reception is invalidated. Cannot be received. For this reason, the transmission signal of the transmission device 2 is received only by the first reception unit 32.
Thus, in the in-vehicle receiving device 3, depending on the distance between the transmitting device 2 and the in-vehicle receiving device 3, only one of the first receiving unit 32 and the second receiving unit 33 can receive a transmission signal. appear.
In this configuration, it is preferable that the antenna 34 and the antenna 35 are installed apart from each other because the difference in reception sensitivity between the first receiver 32 and the second receiver 33 is significant. Specifically, antenna 3
4 may be installed in front of the vehicle or near the door, and the antenna 35 may be installed on the roof or window so that the antenna 34 and the antenna 35 are separated as much as possible.

And the control part 31 with which the vehicle-mounted receiving apparatus 3 is provided WHEREIN: When the transmission signal from the transmission apparatus 2 is received, which of the 1st receiving part 32 or the 2nd receiving part 33 received, and the received transmission signal A control signal is output to the vehicle side circuit 4 based on the ID included in the.
Hereinafter, the operation of the control unit 31 will be described.

FIG. 4 is a flowchart showing the operation of the in-vehicle receiving device 3, and particularly shows the operation of the control unit 31.
During the operation of the in-vehicle receiving device 3, the control unit 31 is in a standby state for reception of a radio signal (step S <b> 11), and receives a radio signal by the first receiving unit 32 or the second receiving unit 33 (
Step S11; Yes), determination of the receiving unit that has performed reception, and I included in the received signal
D is discriminated (step S12).

When the first reception unit 32 receives a wireless signal (step S13; Yes) and the received wireless signal includes the first ID (step S14; Yes), the control unit 31 is configured to control the vehicle door. A door lock control signal for instructing locking is generated and output to the door lock controller 41 (step S15), and the process returns to the standby state (step S11).
Moreover, a radio signal is received by the 1st receiving part 32 (Step S13; Yes), and
When the second ID is included in the received wireless signal (step S16; Yes), the control unit 31 generates an unlock control signal for instructing unlocking of the door lock of the vehicle, and the door lock controller 41. (Step S17) and return to the standby state (step S11).

Here, when neither the first ID nor the second ID is included in the radio signal received by the first receiving unit 32 (step S16; No), the control unit 31 waits without outputting a control signal. Return to the state (step S11). For this reason, even if the first reception unit 32 receives a radio signal including the third ID, the control unit 31 ignores the radio signal.

On the other hand, when the wireless signal is received by the second receiving unit 33 (step S13; No), the control unit 31 determines whether or not the wireless signal includes the third ID (step S18).
When the third ID is included, the detection value of the illuminance sensor 43 provided in the headlight controller 42 is acquired (step S19), and it is determined whether or not the surroundings of the vehicle is a bright environment (step S20).
When the periphery of the vehicle is bright (step S20; Yes), the control unit 31 generates a control signal for instructing the horn to output and outputs the control signal to the horn drive unit 45, and a control signal for instructing the blinking of the emergency blinking indicator lamp. And output to the emergency flashing indicator controller 44 (step S
21) Return to the standby state (step S11).
When the surroundings of the vehicle are not bright (step S20; No), the control unit 31 generates a control signal instructing lighting of the headlamp, outputs the control signal to the headlamp controller 42, and blinks the emergency flashing indicator lamp. Is generated and output to the emergency blinking indicator controller 44 (step S22), and the process returns to the standby state (step S11).

In addition, when the third ID is not included in the wireless signal received by the second receiving unit 33 (step S18; No), the control unit 31 is in a standby state (step S) without outputting a control signal.
Return to 11). For this reason, even if the second reception unit 33 receives a wireless signal including the first ID or the second ID, the control unit 31 ignores the wireless signal.

The operation of the in-vehicle receiving device 3 is summarized as follows.
(1) When a radio signal including the first ID is received by the first receiver 32, the door lock of the vehicle is locked.
(2) When a radio signal including the second ID is received by the first receiver 32, the door lock of the vehicle is locked.
(3) When a radio signal including the third ID is received by the second receiver 33, an operation for notifying the position of the vehicle is performed. When it is bright, the position is notified by an emergency flashing indicator and a horn, and when it is not bright, the position is notified by a headlamp and an emergency flashing indicator.

As described above, according to the keyless entry system 1 according to the embodiment to which the present invention is applied, the in-vehicle receiving device 3 including the first receiving unit 32 and the second receiving unit 33 having different receiving sensitivities is mounted on the vehicle. In the keyless entry system 1 having a configuration in which a wireless signal is transmitted from the transmission device 2 to the in-vehicle reception device 3 in response to a user operation, the control unit 31 receives the first reception unit 32 on the side having low reception sensitivity. If the control signal is output to the door lock controller 41 to instruct the locking or unlocking of the door lock, and the radio signal is received by the second receiving unit 33 on the side having high reception sensitivity, the door lock controller 41 is not locked. A control signal related to the operation is output. Thereby, when receiving a radio signal, it is possible to perform operations corresponding to the first receiving unit 32 and the second receiving unit 33 having different reception sensitivities, and thus the distance between the transmitting device 2 and the in-vehicle receiving device 3 Different operations can be executed according to the transmission function, and multi-function can be realized without complicating the transmission device 2.

Specifically, when the control unit 31 receives a radio signal by the second receiving unit 33, the control unit 31 outputs a control signal for instructing the headlamp controller 42 to turn on or blink the headlamp, and the emergency blinking is performed. A control signal for instructing lighting or blinking of the emergency blinking indicator lamp is output to the indicator lamp controller 44, or a control signal for instructing the horn to ring is output to the horn drive unit 45. For this reason, when the transmission device 2 and the vehicle-mounted reception device 3 are separated from each other, a notification operation for notifying the user of the position of the vehicle is performed by turning on or blinking the headlight or the emergency blinking indicator light or by sounding the horn. be able to.
In this notification operation, the control unit 31 performs switching between lighting or blinking operation of the headlamp and ringing of the horn according to the brightness around the vehicle based on the detection value of the illuminance sensor 43. Let For this reason, the horn can be sounded during the daytime when it is difficult to see the light, and the headlamp can be turned on at night so that effective notification can be performed.

Here, since the first receiving unit 32 has low receiving sensitivity, it does not receive a radio signal from the transmitting device 2 located far away, and the second receiving unit 33 has high receiving sensitivity, so that the transmitting device is in a close position. When a radio signal from 2 is received, it is saturated and reception is invalidated. Therefore, since the first receiving unit 32 and the second receiving unit 33 are substantially switched according to the distance between the transmission device 2 and the in-vehicle reception device 3 to receive the radio signal, the configuration of the transmission device 2 is complicated. And switching between multiple functions.
Further, there is no particular rationality and convenience for locking and unlocking the door lock of the vehicle from a remote place. For this reason, high convenience is realizable by making the receiving sensitivity of the 1st receiving part 32 low, and enabling locking and unlocking of a door lock from near distance.
On the other hand, the operation for notifying the position of the vehicle is useful when the position of the vehicle is unknown. For this reason, since the user can know the position of the vehicle even if the transmission device 2 is far away from the in-vehicle reception device 3 by increasing the reception sensitivity of the second reception unit 33, there is exceptional utility. .

Furthermore, the keyless entry system 1 includes a first key switch 22, a second key switch 23, and a third key switch 24, and the transmission device 2 corresponds to these key switches.
Thus, three types of wireless signals including the first to third IDs can be transmitted. For this reason, it is possible to transmit a wireless signal of a type corresponding to a user operation with a simple configuration.
The in-vehicle receiving device 3 transmits a control signal (door lock control signal, unlock control signal) to the door lock controller 41 only when the first receiving unit 32 receives a radio signal including the first ID or the second ID. ) And a control signal is output to the headlamp controller 42, the illuminance sensor 43, and the horn drive unit 45 only when a radio signal including the third ID is received by the second receiving unit 33.

In other words, when a radio signal including the third ID is received by the first receiver 32 and when a radio signal including the first ID or the second ID is received by the second receiver 33, In either case, an operation such as output of a control signal is not performed. That is, the first receiving unit 32 ignores the wireless signal including the third ID, and the second receiving unit 33 determines the wireless signal including the first ID and the second ID.
Ignore radio signals containing

For this reason, both the first receiver 32 and the second receiver 33 are affected by the distance between the transmitter 2 and the in-vehicle receiver 3 and the reception sensitivity of the first receiver 32 and the second receiver 33. Even when a radio signal is received at the same time, the locking and unlocking of the door lock and the notification of the vehicle position can be reliably switched and executed. Further, since the user only has to operate a key switch corresponding to a desired operation, high convenience can be realized by a simple operation.

In this configuration, the transmission device 2 transmits three types of radio signals including the first to third IDs, but the transmission output and frequency of these three types of radio signals are common. For this reason, the reliable operation | movement of the vehicle-mounted receiver 3 is realizable, without complicating the structure of the transmitter 2. FIG.

In the above embodiment, the transmission device 2 is configured to transmit a radio signal including the first to third IDs. However, the present invention is not limited to this, and is used in combination, for example. An identification code unique to the transmitting device 2 and the in-vehicle receiving device 3 may be included in the radio signal. In this case, even if a plurality of keyless entry systems 1 are used in close proximity, radio signals are not confused between the plurality of keyless entry systems 1, and each keyless entry system 1 can operate reliably. In the above embodiment, the room lamp control unit that controls lighting of the vehicle room lamp is connected to the control unit 31.
It is good also as a structure which outputs a control signal from the control part 31 to a room lamp control part. in this case,
When a radio signal is received by the second receiving unit 33, the position of the vehicle can be notified by turning on the room lamp. Here, if the room lamp is turned on only when it is determined that the surroundings of the vehicle are dark based on the detection value of the illuminance sensor 43, the control unit 31 suppresses power consumption and efficiently notifies. Yes.
In addition, the keyless entry system 1 described in the above embodiment is merely an example of the configuration. For example, specific details such as the shape of the housing 20 and the number of key switches can be arbitrarily changed. It is.

It is a block diagram which shows the functional structure of a keyless entry system. It is a top view which shows the structural example of a transmitter.
