Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a theft alarm device for preventing theft of a vehicle, and more specifically, monitoring the power consumption of a battery during an alarm and alarming until the capacity of the battery falls below a predetermined value. The present invention relates to a vehicle burglar alarm device.

[0002]

2. Description of the Related Art There are various types of vehicle burglar alarm systems. Among them, the one generally used has a transmitter and a receiver, the transmitter is carried by the owner of the vehicle as a key of the vehicle, and the receiver is a type of theft alarm attached to the vehicle. It is a device.

From the transmitter, a transmission signal for instructing locking and unlocking of the vehicle is transmitted to the receiver, and the receiver inputs the signal to the control device mounted on the vehicle and executes the instruction of the transmission signal. Let Further, the control device is provided with a detector group for detecting the open / closed state of the door of the vehicle, etc., and constantly monitors the state of the vehicle after the activation of the theft alarm function.

When the door is locked by the transmission signal with all the openable and closable parts of the vehicle closed, the vehicle is automatically placed under the surveillance of the burglar alarm device. After that, when the detector group detects that the vehicle door or the like has been opened, the theft alarm device turns on the lamps provided on the vehicle and sounds a horn to prevent theft. Tell others around you.

By the way, lamps used for theft alarm,
The horn uses what the vehicle always has, such as a stop lamp, turn signal lamp, and horn.The power related to this is supplied from the battery of the vehicle, and the vehicle stops while the theft alarm is issued. The battery cannot be charged because it is present. Therefore, when the alarm is issued for a long time, a situation may occur in which the battery does not have electric power for rotating the starter motor of the vehicle after the alarm is stopped.

In the conventional theft alarm device, in order to prevent such a situation, the time for issuing an alarm is set to be short, and this is repeated a plurality of times to draw attention to the surroundings while suppressing power consumption. I was extending the time.

This method will be described with reference to the flow charts of FIGS.

When the door lock signal is received, the theft alarm device body first judges whether the ID code superimposed on the door lock signal is a specified one (S1, S2), I
When it is confirmed that the D code is stored in the ID code storage device 25, the open / closed state of the openable / closable portions of the door, the trunk, and the hood is detected. As a result, if any of them are open, a warning sound is emitted to notify the sender of the door lock signal that the vehicle is in an inappropriate state for setting the door lock and theft alarm mode. (S3, S7).

On the other hand, when all of the door, the trunk and the hood are closed, the door is locked and, after a predetermined time has elapsed, the theft alarm mode is automatically set (S4).

In the theft alarm mode, when a door, a trunk or a hood is opened without receiving a door unlock signal on which a specified ID code is superimposed, a theft alarm is provided by a lighting device or the like provided in a vehicle. Is a mode for issuing. Therefore, until the door unlock signal is received, the state of the door, the trunk, and the hood is continuously detected (S5, S6), and either the door, the trunk, or the hood is opened without receiving the door unlock signal. When it detects that, the horn is sounded, all the lamps such as the room lamp, the stoplight, and the turn indicator are turned on, and the theft alarm is issued (S11).

As described above, the time and the number of times of issuing the theft alarm are limited in advance because it is necessary to leave electric power for rotating the starter motor in the battery. Therefore, the alarm time is measured by the alarm timer A at the same time as the alarm is generated, and after the alarm is given for a predetermined time, for example, 2 minutes, this number is counted by the counter A (S13, S1
4).

The theft alarm suppresses power consumption by repeating the alarm for 2 minutes and the stop for 2 minutes as one set. For the theft alarm, whether the number of alarms counted by the counter A reaches a preset number n,
Alternatively, the operation is repeated until the theft alarm device receives the alarm stop signal.

The current related to such an alarm is generally 10 to 15A.

[0014]

However, in such a conventional vehicle anti-theft device, the alarm time and the number of times of one alarm are decided at the time of design, and the alarm time and the number of alarms are actually stored in the battery of the vehicle issuing the alarm. Since the electric power is determined independently of the electric power stored, there is a problem that the electric power stored in the battery cannot keep the electric power necessary for the rotation of the starter motor.

The power generation capacity of the battery is affected by the outside temperature. It is a well-known fact that it is difficult to start the starter motor, especially in cold regions, and the amount of electric power left for starting the starter motor cannot be uniquely determined.

The present invention has been made to alleviate the above problems, and is necessary for more reliable starting of a vehicle by monitoring the electric power remaining in the battery rather than the voltage of the battery as well as the operation of the alarm function. It is an object of the present invention to provide a burglar alarm device for a vehicle, which can secure various electric power.

[0022]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of the theft alarm device according to the first embodiment.

The burglar alarm device of the first embodiment comprises a transmitter (not shown) carried by the owner of the vehicle and a burglar alarm device main body 100 having an antenna 26 as a receiving means. The theft alarm device main body 100 has a detector group for detecting the state of the vehicle, a plurality of alarm means for preventing theft based on the detection information of the detector group, and a control device for controlling them.

The detector group consists of the hood switch 2, the trunk switch 4, the door switch 6, and the lock sensor 8. The hood switch 2 detects the open / closed state of the hood on the front of the vehicle, and the trunk switch 4 detects the open / closed state of the trunk at the rear of the vehicle.
In both cases, this state is detected by opening and closing the contact points of the switch generated by opening and closing.

The door switch 6 is attached to each door of the vehicle and detects whether or not the door is completely closed, and is generally known as a device for notifying an occupant of the "half door state". It is what The lock sensor 8 has a door switch 6,
Further, it is to detect that it is locked. The detection information detected by the detector group described above is input to the CPU 10, which is a control device, via the input interface 24.

In the present embodiment, a battery voltage detector 60 is provided together with the above-mentioned detector group, and the electric power stored in the battery 50 is obtained from the detected voltage value detected by the battery voltage detector 60. There is.

The procedure will be described below.

The detection voltage value detected by the battery voltage detector 60 is input to the CPU 10 through the input interface 24, like the detection information of the detector group described above. C
The PU 10 has a built-in memory 20, and the memory 20 stores data indicating the relationship between the detected voltage value of the battery 50 and the electric power remaining in the battery 50.
Is the battery 50 from the detected voltage value based on this data.
Calculate the power remaining in.

While the alarm is being issued, the battery voltage detector 60 sequentially detects the voltage of the battery 50, and this value is C
Input to PU10. Therefore, the CPU 10 can calculate and monitor the value of the electric power consumed by the alarm and remaining in the battery 50, which is decreasing.

On the other hand, the alarm means comprises a room lamp 16, a lamp 18, and a horn 22.

The room lamp 16 normally functions as an interior lamp, and automatically turns off when the door is closed. The lamp 18 is a general term for a turn signal indicator, a stop lamp, an illuminating lamp, etc. provided on the vehicle. Horn 22
Is usually used as a signal between vehicles.

The CPU 10, which is the control means, controls the entire vehicle theft alarm device body 100, and the ID storage device 25 for storing a specific ID determined by the vehicle.
And a memory 20 that is a means for storing a predetermined battery voltage, which will be described later, and an alarm is issued to each alarm means based on the information detected by the detector group and the battery voltage detector 60 described above. Or it has instructed to stop.

In the theft alarm device main body 100, when a transmission signal for instructing door locking and subsequent theft alarm processing is transmitted from the transmitter, the transmission signal is received by the antenna 26 and superimposed on the transmission signal. The ID code is collated with the ID code stored in the ID code storage device 25. As a result of this comparison, if the ID code of the transmission signal is the predetermined one, the door of the vehicle is locked by the door lock 12 based on the detection information of the detector group, and thereafter the state of the vehicle is detected by the detector group. To monitor.

That is, when the transmitter is instructed to open and close the vehicle door by the transmission signal on which the ID code is superimposed, the CPU 10 performs the process of locking the door depending on the result of the ID code collation and the state of the vehicle. It is determined whether or not, and the door lock 12 is instructed. Further, when it is determined that the vehicle may be stolen by the information from the detector group, the room lamp 16, the lamp 18, and the horn 22 notify the surroundings.

The current consumed during the theft alarm is about 10
15A, the alarm functions until the occupant cancels the theft alarm with the transmitter 1 or a preset condition is satisfied.

As described above, the battery voltage detecting means 6
0 detects the voltage of the battery 50 and inputs it to the CPU 10. In the first embodiment, the CPU 10 controls to stop the alarm function when the voltage value detected by the voltage detector 60 becomes 11 V or less, for example. In this embodiment, 11
The reason why the value of V is set as the condition for stopping the alarm is that the vehicle has no other electrical component that consumes particularly large power and the outside air temperature is 2
This is because it is estimated that the voltage value required to secure the electric power required to start the starter motor is about 11 V when it is assumed to be about 0 to 30 ° C.

Therefore, when the vehicle burglar alarm device of the first embodiment is incorporated in a vehicle, if there is a condition that there is a device with large power consumption in other electric components, especially if it is used in a cold region, this 11V It is necessary to set a higher voltage value. In this way, the voltage value calculated from the minimum electric power required to start the starter motor based on the relationship between the electric power and the voltage is hereinafter referred to as a predetermined voltage value.

In the present embodiment, the predetermined voltage value is set according to the condition of the vehicle and stored in the memory 20 in advance.

Next, FIG. 4 and FIG. 3 are flowcharts showing the processing performed by the theft alarm device of the present embodiment.

The activation of the theft alarm device of the present embodiment starts when the door lock signal is received.

When the theft alarm device main body 100 receives the door lock signal (S21), the CPU 10 inquires the ID code superimposed on the received door lock signal to determine whether the signal is transmitted from a predetermined transmitter. Is determined (S2
2). As a result, when the ID code of the door lock signal matches the ID code stored in the memory 20, the detector group and the CPU 10 detect and judge the open / closed states of the door, the trunk, and the hood (S23).

When any one of the door, the trunk and the hood is open, the theft alarm mode cannot be set. Therefore, a warning sound is emitted to notify the sender of the door lock signal that there is a release point. (S27). If the door, trunk, and hood are all closed, the theft alarm device locks the door and then automatically sets the theft alarm mode (S24).

In the theft alarm mode, the hood switch 2, the trunk switch 4, and the like until the door unlock signal is received.
In this mode, detectors such as the door switch 6 and the lock sensor 8 continue to detect the open / closed state of the door, trunk, and hood. Before entering the theft alarm mode and instructing to unlock the door, if any of the door, trunk, and hood switch is detected to be opened, the horn 22 sounds and the room lamp 16 and the lamp 18 are turned on. The alarm for theft is issued (S30), and at the same time as the alarm for the theft is issued, the timer A starts counting for 2 minutes (S31). The timer A measures the time during which the horn 22, the room lamp 16 and the lamp 18 continue to operate with one alarm.
After the lapse of 2 minutes, the timer A is cleared to turn off the horn 22, turn off the room lamp 16 and the lamp 18, and stop the alarm (S32, S33).

At the same time when the alarm is stopped, the timer B is set to 2
Start minute counting. The timer B measures the time to stop the alarm (S34). When the alarm stop time has elapsed, it is determined whether or not an alarm cancellation signal has been transmitted (S36). When the alarm cancellation signal is received, the alarm is stopped and the process immediately returns to the start. In the process described above, the process performed in the present embodiment and the theft alarm device listed in the conventional example is substantially the same, whereas the theft alarm device of the conventional example counts the number of times the alarm is issued, The theft alarm device of the present embodiment is different only in that this counting is not performed.

This difference is that the conventional theft alarm device limits the power consumption accumulated in the battery 50 by limiting the number of alarms, whereas the present embodiment detects the voltage of the battery 50. Then, the alarm is generated until the electric power remaining in the battery 50 reaches the minimum necessary for starting the vehicle.

That is, when the alarm release signal is not received, the detected voltage value of the battery 50 detected by the battery voltage detector 60 is compared with the predetermined voltage value stored in the memory 20 (S37).

If the detected voltage value of the battery 50 is equal to or higher than the predetermined voltage, the alarm for 2 minutes and the alarm for 2 minutes are stopped again, and the time for issuing the theft alarm is extended. The theft alarm with one set of alarm generation and stop is repeated until the occupant releases the alarm or the detected voltage value of the battery 50 reaches a predetermined voltage value. Or, if it becomes less than that, a process for stopping the alarm is performed.

In this embodiment, in S30,
The first alarm is issued without looking at the voltage of the battery 50. The reason is that the battery 50 does not store electric power for rotating the starter motor at the time of entering the theft alarm mode. Without giving an alarm, it will be damaged by theft, and the reliability of the theft alarm device will decrease. Therefore, in such a case, it is considered that a larger problem is that the alarm function cannot be performed at all than the inability to rotate the starter motor of the vehicle after the alarm is stopped, and such processing is performed.

[0050]

Further, in the present embodiment, the voltage value of the battery 50 is detected every time the alarm stop processing is completed. However, such voltage detection can be performed more accurately by applying current to the battery 50. Since a high measured value is obtained, the battery is always
It may be possible to continue to detect the voltage value of 0 in an analog manner and stop the alarm at the same time when the detected voltage value of the battery 50 reaches a predetermined voltage value even while the alarm is being issued. .

As described above, in the first embodiment of the present invention, the alarm is intermittently issued until the electric power remaining in the battery becomes the minimum necessary to start the vehicle, and the substantial alarm is issued. By shortening the time, it is possible to extend the time during which it is possible to call attention to the surroundings while suppressing the power consumption related to the alarm.

Further, a voltage value capable of supplying the minimum electric power required to rotate the starter motor is input to the memory as a predetermined voltage value and compared with the actually measured voltage value of the battery 50 to determine the time to stop the alarm. By doing so, it is possible to prevent the alarm from being stopped with sufficient power remaining in the battery 50, or it is possible to prevent the irrationality that the starter motor of the vehicle cannot rotate after the alarm 50 has been used up due to exhaustion of the battery 50 power. When the remaining electric power of the battery is sufficient, the alarm is prioritized, and when the remaining electric power is insufficient, the electric power is secured for starting the vehicle, so that both the alarm and the electric power can be secured.

Furthermore, since the electric power left for rotating the starter motor can be changed in consideration of other electric components provided in the vehicle, it is possible to flexibly cope with the situation of the vehicle. Is.

Next, a second embodiment of the present invention will be described below.

The vehicle theft alarm device of the second embodiment is similar in appearance and structure to the vehicle theft alarm device of the first embodiment. FIG. 2 shows a block diagram of the theft alarm device 200 according to the second embodiment. As shown in FIG. 2, a battery voltage detector 60 and a battery temperature detector 61 are provided, which is a unique configuration of the theft alarm device of the second embodiment.

The reason why the temperature of the battery 50 is detected together with the voltage of the battery 50 is as follows. As is well known, the battery 50 contains a large amount of lead in dilute sulfuric acid which is an electrolytic solution. It is a wet battery that charges and discharges by inserting two plates facing each other. Therefore, the chemical reaction rate of dilute sulfuric acid and lead changes with the ambient temperature, and the current flowing between the lead plates changes accordingly. When such a change occurs, even if the detected voltage value of the battery is the same, it is possible that the electric power changes. For example, it is well known that it is difficult to start an engine in a cold region, but such a phenomenon is also caused by a decrease in chemical reaction due to a low temperature.

Therefore, when the alarm is issued while monitoring the power of the battery 50, it is effective to consider the temperature of the battery 50 in order to more accurately obtain the power required to start the engine.

The temperature of the battery 50 can be measured either indirectly or directly. FIG. 3 is an example showing a method of indirectly measuring the temperature of the battery 50.

The battery 50 is mounted in the engine room of the vehicle as shown. In the present embodiment, a thermometer 61 corresponding to a battery temperature detector is attached to the side surface of the battery 50, and the temperature measured by the thermometer 61 is adopted as the detected temperature of the battery 50.

The CPU 10 stores the detected temperature of the battery 50 detected by the thermometer 61 and the detected voltage value measured by the battery voltage detector 60 in the memory 20 based on the data relating the electric power and the voltage depending on the temperature. , Calculates the voltage value required to supply the minimum power required to start the vehicle. Also in this embodiment, this voltage value is referred to as a predetermined voltage value.

In the second embodiment, for example, the CPU 10
-15 ° C or less, -14 ° C or more and 0 ° C or less, and 1 ° C or more of three stages of detection temperatures are set in advance, and the thermometer 61 is set accordingly.
If the detected temperature detected by the device is −15 ° C. or lower, it is determined that the cell motor cannot be activated after the theft alarm is stopped if the detected voltage value of the battery 50 becomes 12 V or lower, and the horn 22 and the like are stopped. When the detected temperature of the battery 50 is -14 ° C or higher and 0 ° C or lower, the alarm is stopped when the detected voltage value of the battery 50 becomes 11.5V or lower. Furthermore, when the detected temperature of the battery 50 is 1 ° C or higher. If there is, the alarm is stopped when the battery detection voltage value becomes 11V, and the setting of the predetermined voltage value of the battery 50 that determines the alarm stop is changed according to the detected temperature of the battery 50.

The processing performed by the theft alarm device of the second embodiment is shown in the flow charts of FIGS. 6 and 7, and will be described below.

In this embodiment, the same processing as that of the first embodiment described above is performed until the step S26 of the flowchart shown in FIG. Therefore, the description up to S26 will be omitted here, and the description of the theft alarm processing of this embodiment will be started from S41 of FIG.

Similar to the first embodiment, after entering the difficult alarm mode and before instructing to unlock the door,
When it is detected that any one of the door, the trunk, and the hood is opened, the horn 22, the room lamp 16, and the lamp 18
A 2-minute theft alarm is issued (S41, S4
2). After the alarm for 2 minutes, the alarm stop signal is waited for 2 minutes, and the reception of the alarm release signal is determined (S44, S45,
S47), when the alarm release signal is received, the alarm is stopped and immediately returns to the start to prepare for the next alarm mode.

When the alarm cancellation signal is not received, the CPU 10 determines the predetermined voltage value of the battery 50 based on the data stored in the memory 20 from the detected temperature of the battery 50 detected by the thermometer 61. To do.

For example, if the detected temperature is T1 [° C.] or lower, according to the data stored in the memory 20,
The predetermined voltage value required to rotate the starter motor is V1
It is set to [V] (S48, S52). Similarly, if the detected temperature is T1 [° C] or higher and T2 [° C] or lower, the predetermined voltage value is V2 [V], and if the detected temperature is T3 [° C] or higher, V
The predetermined voltage value is determined according to 3 [V] and the data stored in the memory 20 (S49, S53, S50, S5).
4).

In the present embodiment, the CPU 10 determines the predetermined voltage value in consideration of the detected temperature, compares the determined predetermined voltage value with the detected voltage value, and the detected voltage value of the battery 50 is equal to or higher than the predetermined voltage value. If the value cannot be maintained, the alarm will stop,
While the detected voltage value of the battery 50 is equal to or higher than the predetermined voltage value, the theft alarm for two minutes and the stop of the theft alarm for two minutes are set as one set, and the theft alarm is repeated.

In the present embodiment, the temperature detected on the side surface of the battery is adopted as the temperature detected by the battery 50. However, in order to directly measure the temperature of the electrolytic solution in the battery 50, a probe type thermometer is used inside the battery 50. It is also possible to insert it into the.

Also in the second embodiment, the first alarm is performed without looking at the voltage of the battery 50, and damage due to theft is prevented without issuing the first alarm.

As described above, according to the second embodiment of the present invention, the theft alarm with alarm and stop as one set is repeatedly performed, and the substantial alarm time is shortened.
It is possible to extend the time that can alert the surroundings while suppressing the power consumption required for the alarm.

Further, as a predetermined voltage value, a voltage value capable of supplying the minimum required electric power for rotating the starter motor is input to the memory, and the alarm is stopped by comparing with the actually detected voltage value of the battery 50. By deciding,
It is possible to prevent the irrationality that the alarm is stopped while the battery 50 still has sufficient electric power, or the electric power of the battery 50 is used up and the starter motor of the vehicle cannot be rotated after the alarm is stopped.

Furthermore, since the value of the electric power left for rotating the starter motor can be changed in consideration of other electric components provided in the vehicle, it is possible to flexibly cope with the situation of the vehicle. In addition to the same effect as that obtained in the first embodiment, it is possible to determine the electric power related to the rotation of the starter motor more in consideration of the detected temperature of the battery. . Such a configuration has an object to generate a theft alarm for a long time as much as possible while leaving the electric power necessary for restarting the vehicle, even for a vehicle used particularly in a cold region or a high temperature region. Effective to achieve.

[0074]

As described above, the vehicle theft alarm device according to the present invention consumes the power for starting the vehicle by issuing an alarm while monitoring the power stored in the battery. While preventing accidents, it is possible to issue an alarm for as long as the battery capacity allows, thereby increasing the reliability of the theft alarm device. Once again
To prevent damage from theft without warning
I am
