[Prior art]
In Japan, theft and incidents of vehicle theft and car rage are lower than in Europe but are increasing. In the United States, the number of vehicle thefts is 1.4 million a year (1988) and the number of car thefts is 2.9 million a year (1988), which is a social problem. In Europe, as in the US, there are many thefts. Therefore, in recent years, various antitheft devices for transmitting an emergency situation of vehicle theft to the outside have been considered.

FIG. 11 is a block diagram schematically showing a main part of a conventional theft reporting device. In the figure, reference numeral 11 denotes a transmitter. The transmitter 11 includes a microcomputer 12, a lock switch 13, an unlock switch 14, a transmission circuit 15, an antenna 16, and an ID code storage unit 17 for storing an ID code. Has been.
[0004]
The lock switch 13 and the unlock switch 14 are connected to the input terminal of the microcomputer 12, and when the lock switch 13 or the unlock switch 14 is pushed, the microcomputer 12 stores the door lock command code corresponding to each switch in the ROM (see FIG. (Not shown), and a signal obtained by adding the door lock command code to the ID code is transmitted from the antenna 16 via the transmission circuit 15. A synchronization code is also given before the ID code, but the description thereof is omitted here.
[0005]
Further, the receiving circuit 22 on the main body side of the theft reporting device has the same synchronization code as that of the transmitter 11, and takes the ID code and door lock command code that follow only when the synchronization codes match. .
[0006]
The main microcomputer 21 determines whether or not the ID code included in the signal (ID code + door lock command code) received via the antenna 23 and the receiving circuit 22 matches the ID code stored in the ID code storage unit 24. If they match, processing is performed according to the door lock command code included in the signal and a signal from the door courtesy switch 25 that detects the open / closed state of the door.
[0007]
For example, if the door lock command code indicates door lock and the detection signal from the door courtesy switch 25 is the door closed state, the door lock actuator 27 is controlled to lock the door and the arming is performed. Set to mode (ie, security system set state). If the door lock command code indicates door unlock, the door lock actuator 27 is controlled to unlock the door, the arming mode is canceled, and the disarming mode (ie, the security system is activated). Reset).
[0008]
The automobile telephone device 31 includes a telephone microcomputer 32, a radio device 33, an antenna 34, and a telephone 35, and the navigation device 41 acquires a navigation (hereinafter referred to as NAVI) microcomputer 42 and a travel distance.

[0009]
A NAVI microcomputer 42 and a telephone microcomputer 32 are connected to the main microcomputer 21. When the vehicle theft is detected by the theft detection means 26, the main microcomputer 21 detects the vehicle position captured from the NAVI microcomputer 42. A theft signal including information is transmitted to the monitoring center through a wireless telephone line using the automobile telephone device 31.
[0010]
[Problems to be solved by the invention]
However, when the theft signal is transmitted to the monitoring center through the wireless telephone line using the automobile telephone device 31, a wireless base station is necessary. When the wireless base station is not nearby, the radio wave is transmitted to the necessary place. I can't tell you. In other words, it does not make sense to transmit the theft signal from outside the callable area, and it simply consumes battery.
[0011]
There are various ways of stealing vehicles. For example, when the ignition key is illegally operated (engine start + steering lock release) and the vehicle is driven to steal, or towed by a tow truck and stealed. .
[0012]
In the former case, the engine is operated and the battery is charged. Therefore, even if power is consumed a little, there is no problem. However, in the latter case, the engine is not operated and the battery is charged. Therefore, the wasteful consumption of power becomes a factor that accelerates battery exhaustion.
[0013]
When the battery runs out, the stolen signal cannot be transmitted when necessary (for example, when in a callable area), or even if the stolen vehicle is recovered, driving cannot be started immediately. This causes problems.
[0014]
Whether the engine is operating or not, it is useless to send the theft signal from outside the callable area, and even if it is within the callable area, the engine is not operating Thus, frequently transmitting the theft signal causes a problem that the battery runs out faster.
[0015]
  The present invention has been made in view of the above-described problems, and is capable of preventing the battery from running out when transmitting the theft signal to an emergency organization such as a monitoring center.And theft reporting methodThe purpose is to provide.
[0021]
[Means for solving the problems and effects thereof]
  To achieve the above objectiveTheft reporting device according to the present invention (1) Is a transmission for transmitting a theft signal including own vehicle position information obtained from the own vehicle position detecting means to an emergency organization such as a monitoring center when the occurrence of theft is detected by the theft occurrence detecting means. In a theft reporting device comprising a control means, an engine operation determining means for determining whether or not the engine is operating, and if the engine operation determining means determines that the engine is not operating, the engine is operating. And a timing setting means for setting the transmission timing so that the transmission interval of the theft signal is longer than that in the case where the theft signal is transmitted.
[0022]
  In addition, a theft reporting device (2) Is a transmission for transmitting a theft signal including own vehicle position information obtained from the own vehicle position detecting means to an emergency organization such as a monitoring center when the occurrence of theft is detected by the theft occurrence detecting means. In the theft reporting device provided with the control means, when the engine operation determining means for determining whether or not the engine is operating, and when the engine operation determining means determines that the engine is not operating, The position detecting means includes an operation control means for intermittently operating in correspondence with the transmission timing of the theft signal.
[0023]
  In addition, a theft reporting device (3) Is a transmission for transmitting a theft signal including own vehicle position information obtained from the own vehicle position detecting means to an emergency organization such as a monitoring center when the occurrence of theft is detected by the theft occurrence detecting means. In the theft reporting device provided with the control means, the engine operation determining means for determining whether or not the engine is operating, and when the engine operation determining means determines that the engine is not operating, the transmitting means Is provided with an operation control means for intermittently operating according to the transmission timing of the theft signal.
[0024]
As described in the section “Problems to be Solved by the Invention”, for example, in the case of vehicle theft using a tow truck, the engine is not operating and the battery is not charged. In other words, frequently transmitting the theft signal in such a state is a factor that speeds up the battery.
[0025]
When the battery runs out, even if the theft signal cannot be transmitted when necessary (for example, when in the callable area E), or even if the stolen vehicle is regained, driving may start immediately. The problem of not being possible.
[0026]
  Therefore, the above theft reporting device (1), When the engine is not operating, the transmission interval of the theft signal is made longer than when the engine is operating.
[0027]
  The above-mentioned theft reporting device (2), When the engine is not operating, the vehicle position detecting means (for example, navigation device) is operated intermittently in correspondence with the transmission timing of the theft signal.
  For example, instead of constantly supplying power to the navigation device, power is supplied only when necessary in accordance with the transmission timing of the theft signal.
[0028]
  The above-mentioned theft reporting device (3According to the above, when the engine is not operating, the transmission means (for example, a car telephone device) is operated intermittently in correspondence with the transmission timing of the theft signal.
  For example, instead of constantly supplying power to a car telephone device, power is supplied only when necessary in correspondence with the transmission timing of the theft signal.
[0029]
  In this way, the above-mentioned theft reporting device (1) ~ (3According to any of the above, when the engine is not operating, it is possible to prevent the battery from running up by suppressing battery consumption.
[0030]
  In addition, a theft reporting device (4) Is a transmission for transmitting a theft signal including own vehicle position information obtained from the own vehicle position detecting means to an emergency organization such as a monitoring center when the occurrence of theft is detected by the theft occurrence detecting means. In a theft reporting device provided with a control means, an engine operation determination means for determining whether or not an engine is operating, and a determination as to whether a signal can be transmitted to the emergency engine by the transmission means. A transmission possibility determination means, wherein the engine operation determination means determines that the engine is not operating, and the transmission possibility determination means determines that a signal cannot be transmitted to the emergency engine. In this case, the transmission control means is configured not to transmit the theft signal.
[0031]
As described in the section “Problems to be Solved by the Invention”, for example, in the case of vehicle theft in which an ignition key is illegally operated, and it is driven and stolen as it is, the engine operates and the battery is charged Therefore, even if a little power is wasted, there is no problem. However, for example, in the case of vehicle theft using a tow truck, the engine is not operating and the battery is not charged. Consumption becomes a factor that accelerates battery exhaustion.
[0032]
For example, when the theft signal is transmitted to the emergency organization through a wireless telephone line, the theft signal cannot be transmitted to the emergency organization if the stolen vehicle is out of the callable area. In other words, it does not make sense to transmit the theft signal from outside the callable area, and it simply consumes battery.
[0033]
  Therefore, the above theft reporting device (4According to the above, when the engine is operating, the transmission of the theft signal is not limited, but the engine is not operating and the transmission means transmits the signal to the emergency engine. When it is impossible (for example, when transmitting from outside the callable area), the theft signal is not transmitted.
[0034]
As described above, when the engine is not operating, it is possible to prevent the stolen signal from being transmitted without meaning, and to prevent wasteful consumption of the battery, thereby preventing the battery from running out.
[0035]
Accordingly, there arises a problem that when it is necessary (for example, when it is in a callable area), the theft signal cannot be transmitted, or when the stolen vehicle is recovered, the driving cannot be started immediately. The possibility can be reduced.
[0036]
DETAILED DESCRIPTION OF THE INVENTION
  Hereinafter, a theft reporting device according to the present inventionAnd theft reporting methodEmbodiments will be described with reference to the drawings.
[0037]
FIG. 1 is a block diagram schematically showing a main part of a theft reporting device according to the embodiment (1). However, here, the same components as those in the theft reporting device shown in FIG.
[0038]
In the figure, reference numeral 51 denotes a main microcomputer. The main microcomputer 51 receives an ID code included in a signal (ID code + door lock command code) received via the antenna 23 and the receiving circuit 22 in the ID code storage unit 24. It is determined whether or not it matches the stored ID code, and if it matches, the process according to the door lock command code included in the signal and the signal from the door courtesy switch 25 that detects the open / closed state of the door It has come to give.
[0039]
The main microcomputer 51 is connected to the NAVI microcomputer 42 and the telephone microcomputer 32. When the vehicle theft is detected by the theft detection means 26, the main microcomputer 51 detects the vehicle position captured from the NAVI microcomputer 42. An emergency signal including information and theft information is transmitted to the monitoring center through a wireless telephone line using the automobile telephone device 31.
[0040]
The operation | movement which the main microcomputer 51 performs in the emergency call apparatus which concerns on embodiment (1) is demonstrated based on the flowchart shown in FIG.
[0041]
First, initialization of RAM and the like (not shown) and a flag f indicating an arming state are performed.₁ , Flag f indicating that theft has occurred₂ , Flag f indicating that the transmission of the theft signal has been completed once_Three The flag f indicating that the navigation device 41 is powered off_Four , A flag f indicating completion of the transmission of the theft signal_Five Is set to 0 (S1). However, flag f_Four Is used for main microcomputers 51C and 61 to be described later, and flag f_Five Is used for a main microcomputer 61 and a telephone microcomputer 72 described later.
[0042]
Next, it is determined whether or not an ID code registered in the ID code storage unit 24 has been received, and whether or not the ID code includes a lock command code (S2). If it is determined that the lock command code is included, it is determined whether or not the door is closed based on the output signal from the door courtesy switch 25 (S3).
[0043]
If it is determined that the door is closed, the door lock actuator 27 is controlled to lock the door (S4), and then the flag f₁ Is 1 or not, that is, whether or not the arming mode is set (S5). Arming mode (ie flag f₁ = 1), it skips S6 and S7 and proceeds to S8. On the other hand, if it is determined that the arming mode is not set, the arming mode is set (S6), and the flag f₁ Is set to 1 (S7), and then the process proceeds to S8.
[0044]
In S8, based on the output signal from the theft detection means 26, it is determined whether or not the theft has occurred (S8). If it is determined that the theft has occurred, the navigation device 41 is turned on (S9), and then the alarm horn device 52 is controlled to sound the alarm horn for 60 seconds (S10). Indicating flag f₂ Is set to 1 (S11), and then the process returns to S2. On the other hand, if it is determined that the theft has not occurred, S9 to S11 are skipped and the process returns to S2.
[0045]
As the theft detection method in the theft detection means 26, for example, detection of door opening by the door courtesy switch 25, detection of a broken glass by a vibration sensor, or movement of a person who has illegally entered the vehicle interior is detected. Examples include a method of detecting with sound waves.
[0046]
If it is determined in S2 that the ID code including the lock command code is not received, the ID code registered in the ID code storage unit 24 is received, and the unlock command code is included in the ID code. It is determined whether or not (S12).
[0047]
If it is determined that the unlock command code is included, the door lock actuator 27 is controlled to unlock the door (S13), and then the flag f₁ Is 1 or not, that is, whether or not the arming mode is set (S14). Arming mode (ie flag f₁ = 1), the arming mode is canceled (S15), and the flag f₁ Is set to 0 (S16), and then the process returns to S2. On the other hand, if it is determined that it is not the arming mode, S15 and S16 are skipped, and the process returns to S2.
[0048]
If it is determined in S3 that the door is open, or if it is determined in S12 that an ID code including an unlock command code has not been received, the flag f₁ Is 1 or not, that is, whether or not the arming mode is set (S17). If it is determined that the arming mode is selected, the process proceeds to S8. If it is determined that the arming mode is not selected, the process returns to S2.
[0049]
Next, another operation performed by the main microcomputer 51 in the emergency call apparatus according to Embodiment (1) will be described based on the flowchart shown in FIG. This process is performed by timer interruption every predetermined time.
[0050]
First, flag f₂ Whether or not theft has occurred (S21: related to S11 in FIG. 2). Theft has occurred (ie flag f₂ = 1), a flag f indicating that the transmission of the theft signal has been completed once_Three Is determined to be 1 (S22). Once finished (ie flag f_Three = 1), it is determined whether it is time to transmit the theft signal next (S23). If it is determined that it is time to transmit the theft signal, the process proceeds to S25.
[0051]
It is determined in S22 that the theft signal is transmitted for the first time (that is, flag f_Three If it is determined that = 0, the power of the automobile telephone device 31 is turned on (S24), and the process proceeds to S25.
[0052]
In S25, it is determined whether or not the mobile phone is within a callable area (S25). Since it can be determined by the telephone microcomputer 32 as to whether or not it is within the callable area, the main microcomputer 51 may capture a signal indicating that from the telephone microcomputer 32.
[0053]
If it is determined in S25 that it is within the callable area, the vehicle position information is taken in from the NAVI microcomputer 42 (S26), and the emergency call dial signal (the telephone number of the monitoring center is set) to the telephone microcomputer 32. Use the car phone to output a theft signal including theft code, the vehicle location information, vehicle information (vehicle number, vehicle type, body color), and the current time Then, control is performed to transmit the theft signal to the monitoring center (S27), and then the transmission time is set to be one minute later (S28). Next, flag f_Three Is determined to be 1 (S29), flag f_Three If it is determined that is not 1, the flag f_Three Is set to 1 (S30).
[0054]
According to the theft reporting device according to the above embodiment (1), when the lock switch 13 of the transmitter 11 is operated, the door lock control is performed, the arming mode is set, and the theft detection is performed in the arming mode. When the theft is detected by the means 26, an alarm horn is sounded. On the other hand, when the unlock switch 14 of the transmitter 11 is operated, the door unlock control is performed and the arming mode is released. When theft occurs, a theft signal including the vehicle position information is transmitted to the monitoring center at an interval of 1 minute.
[0055]
However, if the stolen vehicle is out of the callable area, the theft signal cannot be transmitted to the monitoring center. That is, there is no point in transmitting the theft signal from outside the callable area, and it merely consumes battery, so if the stolen vehicle is out of the callable area, the theft signal Is not sent.
[0056]
As described above, according to the theft reporting device according to the embodiment (1), it is possible to prevent the battery from being exhausted by prohibiting the theft signal from being transmitted without meaning and eliminating unnecessary consumption of the battery. it can.
[0057]
Therefore, there is a problem in that the stolen signal cannot be transmitted even when the stolen vehicle is in a callable area, or when the stolen vehicle is recovered, driving cannot be started immediately. The possibility of occurring can be reduced.
[0058]
FIG. 4 is a block diagram schematically showing a main part of the theft reporting device according to the embodiment (2). However, here, the same components as those in the theft reporting device shown in FIG.

First, flag f₂ 1 is determined, that is, whether or not theft has occurred (S31: related to S11 in FIG. 2). Theft has occurred (ie flag f₂ = 1), a flag f indicating that the transmission of the theft signal has been completed once_Three Whether or not is 1 is determined (S32). Once finished (ie flag f_Three = 1), it is determined whether it is time to transmit the theft signal next (S33). If it is determined that it is time to transmit the theft signal, the process proceeds to S36.
[0062]
It is determined in S32 that the theft signal is transmitted for the first time (that is, flag f_Three = 0), the power of the automobile telephone device 31 is turned on (S34), and the flag f_Three Is set to 1 (S35), and the process proceeds to S36.
[0063]
In S36, the vehicle position information is fetched from the NAVI microcomputer 42 (S36), an emergency call dial signal (indicating the telephone number of the monitoring center) is output to the telephone microcomputer 32, and the theft has occurred. A theft code including a theft code, own vehicle position information, vehicle information (vehicle number, vehicle type, body color), and current time is output, and the theft signal is transmitted to the monitoring center using a car phone. Control (S37).
[0064]
Next, it is determined whether or not the ignition switch 53 is on, that is, whether or not the engine is operating (S38). If it is determined that the engine is operating, the transmission time is set to be one minute later (S39). If it is determined that the engine is not operating, the transmission time is set to be ten minutes later. Set (S40).
[0065]
According to the theft reporting device according to the above embodiment (2), when the engine is not operating, the transmission interval of the theft signal is made longer than when the engine is operating. . Therefore, when the engine is not operating, battery consumption is prevented by suppressing battery consumption.
[0066]
Next, a theft reporting device according to Embodiment (3) will be described. However, since the configuration diagram of the theft reporting device according to Embodiment (3) is the same as that of the theft reporting device shown in FIG. 4, the description thereof is omitted here.
[0067]
An operation performed by the main microcomputer 51B in the theft reporting device according to Embodiment (3) will be described. However, the difference between the operation performed by the main microcomputer 51B in the theft reporting device according to the embodiment (3) and the operation performed by the main microcomputer 51A in the theft reporting device according to the embodiment (2) is only the interrupt processing operation. Therefore, here, only the operation will be described based on the flowchart shown in FIG.
[0068]
First, flag f₂ 1 is determined, that is, whether or not theft has occurred (S41: related to S11 in FIG. 2). Theft has occurred (ie flag f₂ = 1), a flag f indicating that the transmission of the theft signal has been completed once_Three Is determined to be 1 (S42). Once finished (ie flag f_Three = 1), it is determined whether it is time to transmit the theft signal next (S43). If it is determined that it is time to transmit the theft signal, the process proceeds to S45.
[0069]
It is determined in S42 that the theft signal is transmitted for the first time (that is, flag f_Three = 0), flag f_Three Is set to 1 (S44), and the process proceeds to S45.
[0070]
In S45, the power of the automobile telephone device 31 is turned on (S45), then the vehicle position information is taken in from the NAVI microcomputer 42 (S46), and the emergency call dial signal (monitoring center telephone) is sent to the telephone microcomputer 32.

Is used to control to transmit the theft signal to the monitoring center (S47).
[0071]
Next, the transmission time is set to be one minute later (S48), and it is determined whether or not the ignition switch 53 is on, that is, whether or not the engine is operating (S49). If it is determined that the engine is operating, the operation is terminated. On the other hand, if it is determined that the engine is not operating, the power of the automobile telephone device 31 is turned off (S50).
[0072]
According to the theft reporting device according to the above embodiment (3), when the engine is not operating, the car telephone device 31 is operated intermittently in correspondence with the transmission timing of the theft signal. ing. Therefore, when the engine is not operating, battery consumption is prevented by suppressing battery consumption.
[0073]
Next, a theft reporting device according to embodiment (4) will be described. However, since the configuration diagram of the theft reporting device according to Embodiment (4) is the same as that of the theft reporting device shown in FIG. 4, the description thereof is omitted here.
[0074]
An operation performed by the main microcomputer 51C in the theft reporting device according to Embodiment (4) will be described. However, the difference between the operation performed by the main microcomputer 51C in the theft reporting device according to the embodiment (4) and the operation performed by the main microcomputer 51A in the theft reporting device according to the embodiment (2) is only an interrupt processing operation. Therefore, here, only the operation will be described based on the flowchart shown in FIG.
[0075]
First, flag f₂ Is 1, that is, whether or not theft has occurred (S51: related to S11 of FIG. 2). Theft has occurred (ie flag f₂ = 1), a flag f indicating that the transmission of the theft signal has been completed once_Three Whether or not is 1 is determined (S52). Once finished (ie flag f_Three = 1), the flag f_Four Is determined to be 0, that is, whether or not the navigation apparatus 41 is powered on (related to S53: S66).
[0076]
The navigation device 41 is powered on (that is, the flag f_Four = 0), it is determined whether it is time to transmit the theft signal next (S54). If it is determined that it is time to transmit the theft signal, the process proceeds to S55.
On the other hand, according to the determination in S52, the theft signal is transmitted for the first time (that is, the flag f_Three = 0), skip S53 and S54 and proceed to S55.
[0077]
In S55, it is determined whether or not the ignition switch 53 is on, that is, whether or not the engine is operating (S55). If it is determined that the engine is operating, the power of the automobile telephone device 31 is turned on (S56), then the vehicle position information is taken from the NAVI microcomputer 42 (S57), and an emergency call is made to the telephone microcomputer 32 A dial signal (indicating the telephone number of the monitoring center) is output, and a theft code indicating that the theft has occurred, own vehicle position information, vehicle information (vehicle number, vehicle type, body color), and current time are included. A theft signal is output, and control is performed so as to transmit the theft signal to the monitoring center using a car phone, and further control is performed so as to keep the telephone line connected to the monitoring center connected (S58). Thereafter, the transmission time is set to be one minute later (S59), and the process proceeds to S67.
[0078]
On the other hand, if it is determined in S55 that the engine is not operating, the power of the automobile telephone device 31 is turned on (S60), and it is determined whether or not the area is within the callable area of the automobile telephone (S61).
[0079]
If it is determined that it is within the callable area, the vehicle position information is taken in from the NAVI microcomputer 42 (S62), an emergency call dial signal is output to the telephone microcomputer 32, and the theft has occurred. A theft signal including the theft code, own vehicle position information, vehicle information, and the current time is output, and control is performed to transmit the theft signal to the monitoring center using a car phone (S63). Thereafter, the transmission time is set to be 10 minutes later (S64), the power of the automobile telephone device 31 and the navigation device 41 is turned off (S65), and the flag f_Four Is set to 1 (S66), and the process proceeds to S67.
[0080]
In S67, the flag f_Three Is determined to be 1 (S67), flag f_Three If it is determined that is not 1, the flag f_Three Is set to 1 (S68).
[0081]
As a result of the determination in S53, the navigation device 41 is powered off (that is, the flag f_Four If it is determined that = 1), it is determined whether or not it is five minutes before the next time to transmit the theft signal (S69). If it is determined that it is 5 minutes before the transmission time, the navigation device 41 is powered on (S70), and the flag f_Four Is set to 0 (S71).
[0082]
Next, transmission of a theft signal to the monitoring center in the theft reporting device according to Embodiment (4) will be described systematically.
1) When the engine is running: Battery charging is performed, so there is no problem even if power is consumed a little.
・ Theft signal transmission interval: 1 minute
-Car phone device 31: Continue to power on
Navigation device 41: Continue to turn on the power.
2) When the engine is not running
B) Within the call area
・ Theft signal transmission interval: 10 minutes
-Car phone device 31: Power on immediately before the theft signal transmission time
Navigation device 41: Even if the power is turned on, it may not be possible to detect accurate vehicle position information immediately, so the power is turned on 5 minutes before the transmission time of the theft signal.
[0083]
Even if the power is turned on, accurate position information cannot be detected immediately because the position information of the stolen vehicle immediately before the power is cut off (that is, the position information stored in the backup memory of the navigation device 41). ) And the actual position of the stolen vehicle that moves even after the power is turned off.
[0084]
B) Out of call area: Sending a theft signal is meaningless and consumes battery wastefully
・ Theft signal transmission interval: Transmission prohibited
-Car phone device 31: Power on immediately before the theft signal transmission time
