Description

[Detailed Description of the Invention] [Summary] At the same time when an abnormality in the vehicle is detected by an abnormality detection sensor in the car, a calling unit puts the car phone in the car into a calling state,
This is an abnormality notification device that receives a call signal etc. transmitted from the car phone by a receiver outside the car and displays an abnormality of the vehicle on an abnormality display section or a reception display section in the receiver, and is installed in the car phone inside the car. By using this, it becomes possible to easily report vehicle abnormalities to the owner who is far away from the vehicle.

[Industrial application field]

The present invention relates to an abnormality notification device for notifying a vehicle owner outside the vehicle that an abnormality has occurred in the vehicle.

In particular, in order to prevent vehicle theft, it is required to promptly notify the vehicle owner that an abnormality has occurred in the vehicle when a door is forcibly opened or a window is broken.

[Conventional technology]

Conventionally, in order to notify that an abnormality has occurred in the vehicle,
Measures were taken such as blaring the horn inside the car or transmitting weak radio waves. In other words, if an abnormality detection sensor that detects the condition of a specific part of the vehicle, such as the condition of a door, detects that the door has been opened even though the vehicle is stopped, it is assumed that an abnormality has occurred in the vehicle and the system immediately responds. Vehicle owners were notified by sounding the horn or by transmitting extremely weak radio waves that violate the Radio Law.

[Problem to be solved by the invention]

As described above, conventionally, the vehicle owner outside the vehicle has been notified of the occurrence of an abnormality in the vehicle using a sound such as a horn or weak radio waves. In this case, both the sound from the horn and the weak radio waves reach only the vicinity of the vehicle. Therefore, if the vehicle owner is far away from the vehicle, a problem arises in that it is difficult to notify the vehicle of abnormality. As a countermeasure to this, it may be possible to transmit radio waves with a specific frequency using a commercial radio, etc., but a license is required to use the commercial radio.
The number of people who can use it is limited.

The present invention has been made in view of the above-mentioned problems, and it is possible to detect abnormalities in the vehicle without using special equipment such as a commercial radio, even when the vehicle owner is far away from the vehicle. It is an object of the present invention to provide an abnormality notification device that can easily notify a vehicle owner.

[Means to solve the problem]

FIG. 1 is a block diagram showing the first principle configuration of the present invention. Regarding the components similar to those mentioned above,
They are indicated by the same reference numbers.

Here, an abnormality detection unit 1 that detects an abnormality in a vehicle based on sensor information from an abnormality detection sensor installed in the vehicle.
is installed inside the car. Further, a calling unit 2 is provided inside the vehicle, which is activated by the abnormality detecting unit 1 and puts a car phone 3 mounted on the vehicle into a calling state. Furthermore, an abnormality display section 6 is provided inside the receiver 5 outside the vehicle. This abnormality display section 6 displays a call signal Sc transmitted from the car telephone 3 via the relay station 4 and an identification signal S indicating an abnormality of the vehicle.
It receives the pair i and displays the above abnormality.

FIG. 2 is a block diagram showing the second principle configuration of the present invention. In this case, a reception display section 7 is provided which displays an abnormality in the vehicle by directly receiving the calling signal Sc transmitted from the car telephone 3 at the receiver 5. Note that the configurations of the abnormality detection section 1 and the calling section 2 are the same as those shown in FIG.

[For production]

In FIG. 1, as soon as an abnormality in the vehicle is detected, the calling section 2 automatically puts the car telephone 3 in the car into a calling state. Further, the call signal Sc and identification signal Si transmitted from the car phone 3 are transmitted to a receiver 5 held by the vehicle owner via a relay station 4 installed at a predetermined location.
After receiving the information, the abnormality of the vehicle is displayed on the abnormality display section 6 in the receiver 5 to clearly notify the vehicle owner. Here, the identification signal Si is transmitted together with the calling signal Sc so that it can be distinguished from a normal calling operation from a third party.

In FIG. 2, since the calling signal Sc transmitted from the car telephone 3 is directly received by a dedicated receiver 5 without going through the relay station 4, the receiving display section 7 in the receiver 5 receives the calling signal Sc. As long as it shows that Sc has been received,
The vehicle owner immediately recognizes that an abnormality has occurred in the vehicle.

Thus, according to the present invention, even if the vehicle owner is far away from the vehicle, it is possible to clearly notify the user of the occurrence of an abnormality in the vehicle using the car phone 3.

〔Example〕

FIG. 3 is a block diagram showing an embodiment based on the first principle of the present invention. The car phone 3 includes a CPt 131 such as a microcomputer provided in the transmitting/receiving unit 30, and a
an I10 boat 32 that manually inputs data from the outside and outputs control signals from the CP[J 31 to the outside;
It is comprised of a transmitter 33 that modulates the control signal output from this I10 port and transmits it to the outside of the vehicle. Further, the CPU 31 realizes the abnormality detection section 1 and the calling section 2 in which the sensor information Sl to So is manually input.

When a vehicle abnormality is detected from the sensor information S, ~S,, etc., the CPU 31 reads out the pair of the call signal Sc and the identification signal Si, which are normally stored in the memory in the microcomputer, and sends the pair to the I10 port 32. The data is manually transmitted to the transmitter 33 via the transmitter 33. Furthermore, the relay station 4 includes a base station 40 installed in each service area of the mobile phone 3 and a receiver 5.
(FIG. 1) etc., and a calling station 41 for calling. Further, as the receiver 5, a public pager 50, which is portable by the vehicle owner and has a specific call number registered therein, is used. In this case, the calling signal Sc transmitted from the transmitter 33 and including the data of the above-mentioned calling number is
It is received at the base station 40 along with the identification signal S1 and transmitted to the telephone line 4.
2, the pager 50 is sent from the calling station 41 to the pager 50.
sent again to. In this pager 50, the calling signal S
Since the identification signal Si is received together with c, it is possible to easily distinguish between a normal call from a third party and an abnormality in the vehicle.

FIG. 4 is a flow chart for explaining the operation of the embodiment based on the first principle of the present invention. A procedure for notifying a vehicle owner of a vehicle abnormality will be explained according to this flowchart.

As shown in Figure 5, each part of the vehicle includes a door, engine,
Various abnormality detection sensors 10 to 15 that detect windows, communication cables, brakes, and vehicle tilt angles, respectively.
etc. are provided. In FIG. 4, the owner first stops the car and operates the handbrake, then activates the microcomputer and leaves the vehicle. Microcomputer CPU 3
1 (Figure 3), various abnormality detection sensors 10 to 15
It constantly detects whether or not an abnormality has occurred in the vehicle by reading sensor information 51 to S1 from etc. (step a1
Step b). Here, if the CPU 31 detects that the door is open or the vehicle is tilted, it determines that an abnormality has occurred in the vehicle and puts the car phone 3 (Fig. 3) into a calling state (step C). . Further, the pair of the calling signal Sc and the identification number Si is transmitted from the transmitter 33 (FIG. 3) to the base station 40 (FIG. 3) (step d). These pairs of calling signal Sc and identification signal Si are sent to the calling station 41 (third
(Fig. 3) is received by the pager 50 (Fig. 3) having the calling number corresponding to the calling signal Sc (Fig.
Step e). The pager 50 generates a ringing tone in response to the above-mentioned call signal Sc, and the identification signal Si displays characters such as "EMG" on the abnormality display section 6 (Fig. 3) to notify the vehicle owner of the abnormality of the vehicle ( Step f). Thereafter, depending on the case, a control signal may be output from the CPt 131 to put the engine into a state where the engine etc. are not operated, that is, a state where theft is impossible (step g). Here, since commonly used car telephones and pagers are used, there is no need to use special equipment such as business radios, so there are no restrictions on the number of people who can use them. In addition, relay stations 4 (Figure 3) installed throughout the country are used to transmit calling signals Sc, etc. to long distances, so even if the vehicle owner and vehicle are separated by a considerable distance, It is possible to clearly notify the abnormality of the vehicle. In addition, in Fig. 3, characters such as "EMG" are displayed to notify the vehicle owner of an abnormality in the vehicle, but instead, a sound different from the ringing tone is generated to notify the vehicle owner. It is also possible to do so.

FIG. 6 is a block diagram showing an embodiment based on the second principle of the present invention. Here, a control channel receiver 51 is provided as a dedicated receiver 5 for receiving the code of the control channel currently used by the car phone 3. Generally, a specific control channel is designated in the car phone 3, and a code representing this control channel is included in the calling signal Sc from the transmitter 33. However, the control channel assigned to the car phone 3 is not always constant and changes from time to time. Therefore, in the control channel receiver 51, after the receiving section 52 directly receives the calling signal Sc, the signal processing section 53 sequentially scans all the control channels (for example, 600 channels) of the car telephone at regular time intervals. It is checked whether the above code matches the code of any one of all control channels. If both codes match in a certain control channel and the level of the calling signal Sc is at a level corresponding to the distance between the vehicle and the control channel receiver 51, the above-mentioned specific control channel is Assuming that the designated car phone 3 is in a calling state, the vehicle owner is notified of the abnormality of the vehicle by displaying characters or the like on the reception display section 7 or by generating an alarm sound. In this case, since a dedicated control channel receiver 51 is used in place of the pager 50 (FIG. 3) which also has a normal calling function, only a simple display is required on the reception display section 7. . In addition,
Base station 40 with control channel receiver 51 (FIG. 3)
In order to prevent the base station 40 from erroneously assuming that the Rikitomo car phone 3 is malfunctioning when it receives the calling signal Sc, the car phone 3 calls itself when there is an abnormality in the vehicle. Preferably, a calling operation is performed.

Generally, the transmission power of the calling signal Sc is on the order of several watts, so the calling signal Sc reaches much further than conventional weak radio waves. Therefore, the sixth
As shown in the figure, it is now possible to clearly notify a vehicle abnormality to a greater distance than before.

〔Effect of the invention〕

As explained above, according to the present invention, an abnormality reporting device is realized that can automatically make a call from a car phone inside the car and easily notify the owner who is far away from the vehicle of abnormalities in the vehicle. Ru.
