Abstract

<P>PROBLEM TO BE SOLVED: To reduce the power consumption of a battery in an emergency reporting device for a vehicle capable of making a call to a prescribed center if a switch for emergency is operated even when an ignition switch is off. <P>SOLUTION: When the ignition switch 9 is off, only an operation by a switch 6a for emergency is allowed, and a telephone calling operation by the other normal telephone set and by an information switch 6b for the other services is inhibited. If the switch 6a for emergency is operated when the switch 9 is off, a waiting period is changed into a shorter period than that before the operation of the switch 6a for emergency. Accordingly, if the switch 6a for emergency is operated, a telephone call can be immediately made or an incoming call can be received, although waiting has to be made for a very long time so far and a telephone call can not be made till waiting timing comes. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicular emergency notification device, in which an ignition switch of a vehicle is OF.
It relates to the ones that allow emergency calls even when F.

[0002]

2. Description of the Related Art Conventionally, a vehicle emergency notification device disclosed in Japanese Unexamined Patent Publication No. 2010-276681 is well known. In this conventional device, the ignition switch of the vehicle is turned off.
Even in this case, when the emergency switch in the vehicle compartment is operated, an emergency call telephone is used to make a call (call) to a predetermined emergency call center.

[0003]

By the way, the inventor of the present invention has studied the above-mentioned conventional device, and as a result, the emergency call telephone can be called only for emergency.
If you make it a normal phone, that is, the user dials, so that you can call to any destination,
The following problems were found to occur.

That is, when the ignition is turned on, the vehicle self-generates power by the alternator by driving the engine, so there is no problem in battery consumption even when used as an emergency call telephone or a normal telephone. However, on the other hand, when the ignition is off, both the emergency call phone and the normal phone can be called. For example, when the ignition is off, if the normal phone is accidentally used for a long time, There is a problem that the battery consumes a large amount of battery capacity.

Therefore, in view of the above problems, the present invention allows the occupant to operate even when the ignition is off.
An object of the present invention is to reduce the power consumption of a vehicle battery in an emergency call device for a vehicle capable of making an emergency call.

Further, the above-mentioned publication describes that the emergency call telephone is set to the sleep mode when the ignition is off, but in this sleep mode, basically, only when the emergency switch in the vehicle is operated. , Activates an emergency call phone. Therefore, for example, when the ignition switch is off, it is not possible to communicate with the emergency call telephone inside the vehicle from outside the vehicle. Therefore,
Even if the ignition switch is off, it is not possible to handle a service that controls a vehicle device by sending a remote command from outside the vehicle by operating the emergency call telephone.

[0007] Therefore, if the emergency call telephone is always in the standby mode when the ignition switch is off, the above service can be provided. However, if the ignition is off for a long time,
There is a problem that the consumption of the vehicle battery is accelerated and, eventually, the time for providing the service is shortened.

As a countermeasure against this, the waiting operation of the telephone is reduced in frequency of receiving the calling signal as compared with the case of ignition on, for example, by turning on / off the power of the telephone, the power consumption of the battery is reduced. It is possible to extend the service providing time.

However, as a result of the present inventors' examination of the case where the above-mentioned frequency is reduced when the ignition switch is off, the following has been found. That is,
In this situation, if you return to the same standby operation, that is, the operation that remains infrequent after an emergency call is made by the emergency call switch, the phone will receive an emergency call because the time available to receive an incoming call is limited. There is a problem that it is not possible to quickly contact a third party who knows what was done (emergency center, police, emergency center, family of crew, etc.).

In view of the above problems, the present invention reduces the power consumption of the vehicle battery when the ignition is turned off in an emergency notification device for a vehicle which can make an emergency call by the operation of an occupant when the ignition is turned off. It is an object of the present invention to provide an emergency call device for a vehicle that can extend the service providing time and can surely make a call at an early timing after making a call to the center.

[0011]

In order to achieve the above-mentioned object, in the invention according to claim 1, the emergency call telephone generally uses the user to dial an arbitrary destination to make a call to an arbitrary partner. It has a telephone function, and when the traveling switch is off, the operation of the general telephone function is prohibited and the emergency telephone function is allowed to be operable.

This makes it possible to prevent accidentally using the telephone for a long time.

Further, in the invention of claim 1, as in the invention of claim 2, the vehicle has a service switch for calling a predetermined vehicle service center, in addition to the emergency switch, for running. When the switch is off, it is also possible to prohibit the telephone call from the service switch.

In the invention according to claim 4, the power supply to the audio device is automatically stopped when the call by the emergency switch is finished. As a result, when the traveling switch is off, the emergency switch talks to a predetermined center, and when the call ends, the audio device is automatically turned off, so that unnecessary power consumption can be prevented.

Further, in the inventions of claims 5 and 7, when the traveling switch is on, the emergency telephone operates in the first standby mode in which the normal standby operation is performed, and the traveling switch is turned off. Then, the emergency call telephone operates in the second standby mode in which the frequency of receiving the call signal is lower than that in the first standby mode, and when operating in the second standby mode, the emergency call switches to the predetermined center. When a call is made, the frequency after the call is made higher than the frequency in the second standby mode before the call.

As a result, when the emergency switch is operated, the standby operation of the emergency wireless telephone becomes easier to receive the call signal than before the operation of the switch, so that it is known that the emergency call is made. Person, such as the above center, police, emergency center, or family of occupants)
Can be contacted quickly by.

According to the tenth aspect of the invention, when the traveling switch is on, the emergency telephone operates in the first standby mode in which normal standby operation is performed, and when the traveling switch is off, an emergency call is issued. The mobile telephone operates in a second standby mode in which the call signal is received less frequently than in the first standby mode. The frequency in the second standby mode is that the emergency switch is operated when the traveling switch is off. It is characterized in that change control can be performed by a remote command from the predetermined center to the emergency telephone according to the content of the call made to the predetermined center.

By the way, in the vehicle emergency notification device, when the emergency switch is operated while the traveling switch is off, the frequency of automatically receiving the call signal for the standby operation of the emergency notification telephone increases. However, there may be cases where the operation of the emergency switch was an erroneous operation, or when the emergency switch was operated, but it was not a big problem. Therefore, in this case, there is a problem that the battery consumption is accelerated.

According to the tenth aspect of the present invention, the center sends the remote command for making the above change to the notification device according to the contents of the call, so that it is possible to deal with the situation.

Further, in the invention according to claim 11, when the emergency switch is operated, the emergency telephone notifies the emergency notification center that the transmission is a transmission when the traveling switch is off. It is characterized by that.

As a result, the center can know that there is a possibility of transmitting a command for changing the standby operation.

The control unit 4 is a computer that controls the reporting device 1. This is mainly composed of a known one having a RAM, a ROM and a CPU (not shown) as a hardware configuration. However, the program stored in the ROM, that is, its control content has a characteristic part of the present invention. Further, although not shown, the control unit 4 automatically makes an emergency call to the center 201 by detecting the operation of the airbag of the vehicle, and after transmitting the position data at that time, makes a voice call. , Executes the so-called Mayday function.

The GPS receiver 3 is composed of a plurality of artificial satellites.
It is a well-known device that receives a position signal and detects the position of the vehicle. Here, the GPS receiver 3 receives and demodulates signals from, for example, three artificial satellites. Further, the calculation of the vehicle position is performed by the control unit 4, and the calculation result is obtained by the control unit 4.
Is converted to latitude and longitude data.

The key operation unit 6 is for operating a telephone, and has a numeric keypad (not shown), a call key, and an end key for a normal telephone function (general telephone function). The ten-key pad is for inputting a telephone number of an arbitrary party, and is a ten-key numeric keypad from 0 to 9. The calling key is for starting a telephone call operation for the input number, and the end key is for ending the call.

Further, in this embodiment, the key operation unit 6 is
When operated by an occupant, an emergency call key 6a (emergency switch) for making a phone call to the center 201 and an information key 6b (service switch) for inquiring the center 201 of the above-mentioned directions and weather information. Have

The audio device 5 constitutes a hands-free device for making a voice call by the ordinary telephone function or the Mayday function. In this example, the audio device 5 is a well-known audio such as a radio, a CD, a cassette tape, and the audio input / output terminal thereof is connected to the audio input / output terminal of the cellular radio telephone 2.

The audio device 5 has a speaker 5a and a microphone 5b for making a hands-free call.
The speaker 5a is for outputting audio output from a radio, a CD or the like to the inside of the vehicle in the first place, and in this example, is also used for a hands-free call. On the other hand, the microphone 5b is connected to the audio device 5 for a special hands-free call.

With this configuration, the voice from the base station, that is, the voice signal of the other party, is finally transmitted through the path of the cellular radio telephone 2 → the audio device 5 → the speaker 5a to 5
It is output from a. On the other hand, the input voice from the microphone 5b is transmitted through the audio device 5 → the cellular radio telephone 2,
Sent to the base station.

The power supply control unit 7 controls to supply or stop the electric power from the battery 8 mounted on the vehicle to each component of the reporting device 1. As shown in FIG. 2, an ignition switch 9 (hereinafter referred to as an IG switch) that connects the battery 8 and the battery 8 to start the engine and allow the vehicle to travel is connected to the power control unit 7. A power supply line 8b is connected between the power supply control unit 7 and the IG switch 9.

The power control unit 7 has another battery 8,
A power supply line 8a for supplying power from is connected. Such two power supply lines are separately used in the following cases. The power supply controller 7 constantly monitors the input voltage from the power supply lines 8a and 8b.
When the G switch 9 is on, electric power is obtained only from the power supply line 8b from the IG switch 9. On the other hand, when the IG switch 9 is off, the input voltage of the power supply line 8b is 0
However, since the other power supply line 8a is detected to have a predetermined value or more, the power supply system is internally switched so as to supply power from the power supply line 8a.

The power supply control unit 7 receives power from the power supply line 8a or 8b, and the supply destination thereof is the control unit 4 and the audio device 5. That is, the power supply control unit 7 supplies power from the power supply line 7 a to the audio device 5, and supplies power from the power supply line 7 b to the control unit 4. Further, power is supplied to the other components (cellular radio telephone 2, GPS receiver 3, key operation unit 6) through the control unit 4.

In FIG. 2, the control unit 4 and the power supply control unit 7 are connected by a control line (not shown) by serial communication in addition to the power supply line 7b. Can be notified to the control unit 4 and the power supply control unit 7 can turn on / off the power supply to the audio device 5 in response to a command from the control unit 4.

The memory 10, which is a storage unit, stores the telephone number of the center 201, which is a predetermined call destination, the registration number (the above ID) of the vehicle in which the emergency call system terminal device 1 is installed, and information such as the registrant. Is stored.
In addition, this memory stores telephone directory data in which personal telephone numbers used for the general telephone function are registered.
This phonebook data can be operated by operating the key operation unit 6.
It can be read and used when making a call.

Next, the operation of this embodiment will be described with reference to the flowchart of FIG. In FIG. 3, first,
In step S401, it is determined whether the IG switch 9 is off. In this determination, when the IG switch 9 is turned on, a well-known alternator (not shown) mounted on the vehicle starts power generation, so that there is a margin for power supply, and the notification device 1 and the audio device 5 are available. It is equivalent to determining whether or not power supply to the power supply can always be performed. Then, if the determination result is NO, S402
At 0, the flag is set to 0 and normal control is performed.
Here, the normal control is the following operation.

In the normal control, all the power is supplied from the power supply line 8b to the reporting device 1, the control unit 4 is supplied from the power supply line 7b, and the audio device 5 is supplied from the power supply line 7a. As a result, each component can perform its function. For example, the control unit 4 receives a key input from the key operation unit 6 and executes the above-mentioned Mayday function by expanding the airbag. Also, GPS
The receiver 3 starts positioning.

The cellular radio telephone 2 in the normal control, when the power is turned on, carries out processing so as to perform a well-known standby operation. For example, when the cellular radio telephone 2 is powered on, it scans the first perch channel to be captured among the predetermined downlink control channels, and acquires one control channel. Next, the cellular radiotelephone 2 performs position registration with respect to the base station corresponding to the determined control channel, or acquires channel information for performing a standby operation from the base station. The standby operation determines the frequency and time slot of its own paging channel from the above-mentioned channel information from the base station, and periodically receives the paging channel, thereby waiting for a paging signal (incoming call) to itself. The standby mode is set. In the first standby mode, for example, a so-called intermittent reception is performed in which a reception operation of a paging channel is a frame cycle of several hundred milliseconds, and a reception operation is performed for several tens of milliseconds.

When the power is turned on, the audio device 5 under the normal control can operate the audio processing circuit (not shown) including the amplifier inside thereof, the speaker 5a, and the microphone 5b. In normal control, the audio device 5 is always supplied with power. And the audio device 5
Switches between normal audio (radio, CD) operation and hands-free operation according to the operation of the cellular radiotelephone 2. Specifically, radio or CD
If a call is made or an incoming call is received while listening to, the output from the radio or CD is muted so as not to be output from the speaker 5a, and the voice of the other party is output from the speaker 5a. The above is the outline of the normal control.

On the other hand, in the flowchart of FIG. 3, when the result of the determination in step S401 is YES, that is, IG
If it is determined that the switch 9 is turned off, step S40
Go to 3. In step S403, it is determined whether the flag is set to 1. In this step S403, if the IG switch 9 is on, step S402
Since the flag is set to 0 at, the first time the IG switch 9 is turned off and then the routine proceeds to step S403, it is always determined to be NO.

In step S404, the timer is reset, and in the next step S405, the timer is counted (incremented). That is, when the IG switch 9 is turned off from on, the timer is reset and the timer starts counting. Next, in step S406, it is determined whether the timer count T has passed a predetermined time A. The predetermined time A is, for example, 8 hours. Then, if the determination result is NO, the process proceeds to S407, and the cellular radiotelephone 2 is switched to the first control mode.

Here, the first control mode is the same operation as the normal control except that the power of the audio device 5 is turned off, and the cellular radio telephone 2 maintains the standby mode. . On the other hand, when the determination in step S406 is YES and the time after the IG switch 9 is turned off exceeds the predetermined time A, the process proceeds to step S408 and the count time of the timer is
It is determined whether it is within the predetermined time B. This predetermined time B is
In this example, it is 16 hours. And this judgment result is YE
When the timer count T is 8 hours or more and 16 hours or less, the process proceeds to step S410 and switches to the second control mode (the second standby mode of the present invention). Here, the second control mode differs from the first control mode in the following points.

In the first control mode, the cellular radio telephone 2
Became a standby mode in which a call signal was received in a very short cycle, but the cellular radio telephone 2 was turned on and off in the second control mode, so that the call was made in a much longer cycle than in the first control mode. Receive the signal. For example, the power is supplied from the power line 7b for 1 minute every 15 minutes, and the cellular radio telephone 2 performs the standby operation. Therefore, in the second control mode, the frequency of receiving a call signal from the base station is very low in comparison with the first control mode.

When the timer count T has passed the predetermined time B or more, the process proceeds to step S411 to switch to the third mode. Here, the third mode is different from the second control mode only in the power-on / off cycle of the cellular radiotelephone 2, and in the third mode, power is supplied for 1 minute per hour to perform a standby operation. I do. When the IG switch 9 is turned off in this manner, the frequency of receiving the call signal gradually decreases according to the elapsed time. As a result, the power consumption of the battery 8 can be reduced and the service providing time can be extended. For example, the remote service described above corresponds to an example of this service.

Then, steps S407, S410, S
After the processing in 411, the process proceeds to step S412, 1 is set in the flag, and this flowchart is returned.
This flag is set to 1 in the next step S40.
When I proceeded to 3, I made a NO decision by that decision and IG
This is because the timer count continues while the switch 9 is off.

Next, the processing when the emergency call switch 6a is operated when the IG switch 9 is off will be described with reference to the flowchart of FIG. First, in step S501, it is determined whether or not the emergency notification switch 6a is turned on, and if the result of this determination is off, the audio device 5 is processed with the power supply kept off, and this flowchart is returned. On the other hand, when it is determined that the emergency call switch 6a is turned on, the process proceeds to step S502, 0 is set in the flag, and step S5 is performed.
Go to 03.

Here, if 0 is set in the flag in step S502, NO is determined in step S403 in the flowchart described in FIG. 3, and the timer is reset. Therefore, the cellular radio telephone 2
In step S407, the mode is switched to the first control mode. After that, the process proceeds to step S503 to power on the audio device 5, and then proceeds to step S504 to make a telephone call to the center 201. Note that the audio device 5 is turned on because it is necessary for making a hands-free call.

Here, the steps S502 to S50.
The control operation of the cellular radio telephone 2 in No. 4 is as follows.
In the third control mode, it differs depending on the timing when the IG switch 9 is pressed. For example, when the above timing is the first control mode, since the telephone is in a standby state ready to be dialed anytime, the telephone is immediately dialed to the center 201. Further, even when the above timing is in the standby state for turning on the power in the second control mode or in the standby state for turning on the power in the third control mode, it is in the standby state in which the call can be originated as a call in the first place. Make a phone call to 201. The remaining timing is when the power is turned off in the second control mode and the third control mode. In this case, the power is turned on and the normal standby operation is performed, and then the call is sent to the center 201.

As described above, when the IG switch 9 is off and the emergency notification switch 6a is turned on, the first control mode is entered and the normal standby operation is performed for 8 hours. Therefore, even if a call is made with the center 201 for 2 minutes,
After that, for 7 hours and 58 minutes, the cellular radio telephone 2 switches from the standby state before the call, that is, before turning on the emergency switch 6a, to the first control mode in which the call signal is frequently received.

Next, in step S505, the center 2
If it is determined that the call is ended with 01, and if the call is ended, the power supply to the audio device 5 is stopped in step S506 to immediately reduce the power consumption of the battery 8. The cellular radiotelephone 2 continues the standby operation.

As described above, in this example, when the IG switch 9 is off, as shown in FIG.
Only when the switch is turned on, that is, the normal ordinary telephone call and the operation by the information switch 6b are unacceptable and prohibited, so that it is possible to prevent accidentally using the telephone for a long time.

In this example, when the IG switch 9 is off, the standby time is extended and the service providing time from the center 201 is extended by controlling the power supply to the cellular radio telephone 2 to be turned on and off. be able to. Then, in this example, when the emergency switch 6a is operated, the standby operation of the cellular radiotelephone 2 becomes the first standby mode in which the call signal is received in a very short cycle compared to before the switch operation. You can quickly receive contact from a third party (emergency center, police, emergency center, or crew member's family) who knew what was done.

(Second Embodiment) In the above embodiment, the IG
To change the standby mode with the switch 9 off, use the notification device 1
However, in the second embodiment, this change is performed by the command transmitted from the center 201. Hereinafter, this processing will be described based on the sequence diagram of FIG. It should be noted that this process is performed as shown in FIG.
Step S502 is unnecessary, and instead, the following communication is performed between the notification device 1 and the center 201.

First, in process 600, the emergency switch 6
When a is operated, the center 201 and the voice line are connected. After connecting the voice line, the notification device 1 displays the ID, GPS
The position information in the receiver 3 is transmitted, and at the same time, the IG switch 9 is turned off, and the data indicating that the emergency switch 6 is operated is transmitted to the center 201. Then, these data are received by the processing 602 on the side of the center 201, and the contents are grasped. Then, the reporting device 1 and the center 201, after finishing the data communication,
In process 603, a voice call is started. For example, in the center 201, when the data sent from the notification device 1 is received, a data reception confirmation signal is transmitted to the notification device 1, and at the time when this confidence signal is transmitted, switching to a voice call is performed. On the other hand, in the notification device 1, when the data reception end signal from the center is received, the cellular radio telephone 2 outputs the voice to the audio device 5 and the voice from the audio device 5 can be input.

Next, the operator of the center 201 determines whether or not to remotely operate the cellular radio telephone 2 according to the contents of the voice call. For example, a voice call may cause an erroneous operation of the emergency switch 6a, or the emergency switch 6a may be operated, but this may not be a big problem. Then, in this case, the first control mode is always switched to the first control mode, so that the standby operation is performed unnecessarily to expedite the consumption of the battery 6.

Therefore, in this case, the center 201 is
If it is determined that the person is in a burglary condition or if he / she is sick due to illness according to the condition of the occupant, a remote command for controlling the standby operation is again transmitted to the notification device 1 by data communication in process 604. For example, this command is for controlling to enter the first control mode. And
This command is received by the notification device 1 in process 606, and this command is interpreted to change and set the standby mode.

As described above, according to the present embodiment, it is possible to prevent the unnecessary power consumption of the battery 6 from being accelerated by performing an unnecessary standby operation when the IG switch 9 is off. In addition, in the present embodiment, the notification device 1 indicates that the operation of the emergency switch 6a when the IG switch 9 is off is performed by the center 2
Since the information is automatically notified to 01, the center 201 can know in advance that a command for changing the standby operation may be transmitted before the call.

(Modification) In the first and second embodiments, I
When the G switch 9 is turned off, the mode is switched to the first control mode. However, a mode different from this may be prepared, and the standby operation may be performed at a short cycle of, for example, 30 minutes.

In the first embodiment, the control of the standby operation is changed by the notification device 1 alone, and in the second embodiment, it is changed by the remote command from the center 201.
You may combine these.

In each of the above embodiments, the cellular radio telephone 2 is described as a digital telephone, but the present invention can be applied to an analog radio telephone instead of a digital telephone.

The numerical values described in the above embodiments are examples and do not particularly limit the present invention, and may be set arbitrarily according to the vehicle and the service provided.
