[0031]
3 to 5 show flowcharts of programs for the operation of the CPU 5. These programs are started when the user of the in-vehicle terminal 40 leaves the vehicle and operates the operation switch unit 8 to activate the in-vehicle terminal 40.
[0032]
FIG. 3 shows a program for notifying the in-vehicle terminal 40 of another vehicle of an abnormality of the own vehicle. Hereinafter, the program of FIG. 3 will be described.
[0033]
First, in step 100, the CPU 5 determines whether or not an abnormality has occurred. Specifically, it is determined whether or not various abnormality detection signals have been received from the sensors of the abnormality detection unit 4. This determination process is repeated until the determination result becomes affirmative.
[0034]
If an abnormality has occurred, the process proceeds to step 101, and the notification distance and the number of responses are initialized. Specifically, an area for recording the notification distance and the number of responses is secured in the RAM of the memory unit 6 and an initial value is written in the area. The notification distance is a value used for generating an alarm sound only from the in-vehicle terminal 40 of the vehicle within the range of the notification distance from the own vehicle. The number of responses is a value indicating the number of other in-vehicle terminals 40 that have returned a response notification in response to an abnormality occurrence notification described later. The response notification will also be described later. The initial values to be written are, for example, a notification distance of 30 m and a response count of 0.
[0035]
Next, in step 102, an abnormality occurrence notification is created, which is data including information such as the fact that an abnormality has occurred, the current position of the vehicle, the notification distance, and the identification number of the in-vehicle terminal 40 stored in the ROM. In order to transmit the abnormality notification to the surroundings of the host vehicle at a predetermined frequency, the abnormality notification is output to the wireless communication unit 2. The current position of the host vehicle is acquired by input from the host vehicle position detection unit 3. The current position information is a numerical value indicating, for example, latitude and longitude. The notification distance is acquired by reading from a predetermined area in the RAM. In step 102, a flag in the RAM used in the determination processing in step 106 described later is reset, and a stop signal, a setting signal, a clear signal, and a start signal are output to the timer unit 7. As a result, the timer unit 7 starts counting time from the counter value zero. Note that the predetermined value of the counter set by the setting signal is the value of the counter corresponding to a specified time T1 (for example, 3 seconds).
[0036]
Next, in step 103, it is determined whether a response notification has been received from the in-vehicle terminal 40 of another vehicle. Specifically, it is determined whether or not response notification data has been input from the wireless communication unit 2 before the process of step 103 of this time after the process of step 103 of the previous time. The response notification is predetermined data that is transmitted by the vehicle-mounted terminal 40 that has received the abnormality occurrence notification to notify the transmission-source vehicle-mounted terminal 40 that the alarm device 9 is activated. Whether or not a response notification has been received after the previous step 103 until the current step 103 can be determined by using a determination flag provided in the memory unit 6. Specifically, in step 103, the flag is reset immediately after the determination, and when a response notification is input from the wireless communication unit 2 as a process executed in parallel with the process of FIG. The CPU 5 executes the setting process. Then, this determination determines whether or not this flag is set.
[0037]
If there is a response notification, the process proceeds to step 104, the value of the number of responses currently written in the RAM is increased by 1, and then the process proceeds to step 105. If there is no response notification, the process directly proceeds to step 105.
[0038]
In step 105, it is determined whether or not the number of responses in the RAM is equal to or greater than a specified number N1 (for example, 5). The specified number N1 is stored in advance in the flash memory of the memory unit 6, and in this determination process, the value is read and determined.
[0039]
If the number of responses is N1 or more, the process proceeds to step 109, the alarm device 9 is activated by transmitting a control signal to the alarm device 9, and then the process returns to step 100.
[0040]
If the number of responses is less than N1, the process proceeds to step 106, and it is determined whether or not the elapsed time from the previous notification in step 102 is equal to or longer than the specified time T1. Specifically, it is determined whether or not an interrupt signal has been input from the timer unit 7 after the previous processing of step 102. This determination can be made by using the flag reset in step 102. Specifically, as a process executed in parallel with the process of FIG. 3, the CPU 5 executes a process of setting the flag reset in step 102 when an interrupt signal is input from the timer unit 7. Then, this determination determines whether or not this flag is set.
[0041]
If it is determined in step 106 that the elapsed time is equal to or longer than the specified time T1, the process returns to step 103. If it is determined that the elapsed time is less than T1, the process proceeds to step 107.
[0042]
In step 107, it is determined whether or not the notification distance is equal to or greater than the specified distance D1. Specifically, the value of the notification distance recorded in the RAM is read out, and it is determined whether or not it is equal to or greater than the specified distance D1. The specified distance D1 is 100 m, for example. If it is equal to or greater than D1, the process proceeds to step 109, and if it is less than D1, the process proceeds to step 108.
[0043]
In step 109, the alarm device 9 is controlled to emit an alarm sound. Then, the process returns to step 100.
[0044]
In step 108, the notification distance in the RAM is rewritten to a value increased by ΔD. Then, the process returns to step 102. The distance ΔD is, for example, 30 m.
[0045]
If there is an abnormality in the vehicle (see step 100) by the processing of the CPU 5 in FIG. 3 as described above, the fact that the abnormality has occurred, the vehicle position, and the notification distance are transmitted to the in-vehicle terminal 40 of the other vehicle (step 100). 102). When the number of response notifications is less than N1 (see step 105), the elapsed time from the notification is T1 or more (see step 106), and the notification distance is less than D1 (see step 107). The notification distance is increased (see step 108), and the abnormality occurrence notification is performed again. Further, even if the number of response notifications is less than N1 and the elapsed time from notification is T1 or more, if the notification distance is D1 or more (see step 107), the abnormality occurrence notification is not transmitted again. . Further, even when the number of received response notifications is N1 or more, the abnormality occurrence notification is not transmitted. In addition, even if the number of responses is less than N1, if the elapsed time is less than T1, another notification is suspended.
[0046]
FIG. 4 shows a program for a case where an abnormality occurrence notification is received from the in-vehicle terminal 40 of another vehicle. Hereinafter, the program of FIG. 4 will be described.
[0047]
When this process starts, it is first determined in step 200 whether or not an abnormality occurrence notification received from another in-vehicle terminal 40 is input from the wireless communication unit 2, and this determination process is repeated until the input is received.
[0048]
If an abnormality occurrence notification is received, the process proceeds to step 201, where the distance between the position of the vehicle and the position of the vehicle on which the in-vehicle terminal 40 that has transmitted the abnormality occurrence notification is mounted, that is, the distance between the two vehicles is It is determined whether or not it is larger than the notification distance included in the abnormality occurrence notification. Specifically, this determination process acquires the current position of the own vehicle from the own vehicle position detection unit 3, calculates the distance between this current position and the current position of the transmission source included as information in the abnormality occurrence notification, It is determined whether the calculated distance is larger than the notification distance. If the distance between the two vehicles is larger than the notification distance, the process returns to step 200 to determine reception of a new abnormality occurrence notification. If the distance between the two vehicles is equal to or less than the notification distance, the process proceeds to step 202.
[0049]
In step 202, a response notification for transmitting to the transmission source of the abnormality occurrence notification is created and output to the wireless communication unit 2. The response notification is data for notifying the transmitting in-vehicle terminal 40 when the in-vehicle terminal 40 that has received the abnormality occurrence notification activates the alarm device 9. Specifically, this response notification includes predetermined data indicating that it is a response notification, an identification number of the in-vehicle terminal 40 that transmits the response notification stored in the ROM, and the like.
[0050]
In step 203, the alarm device 9 is operated by transmitting a control signal to the alarm device 9. As a result, the alarm device 9 emits an alarm sound. In addition, a stop signal, a setting signal, a clear signal, and a start signal are output to the timer unit 7. As a result, the timer unit 7 starts counting time from the counter value zero. Note that the predetermined value of the counter set by the setting signal is the value of the counter corresponding to a specified time T2 (for example, 5 minutes). Further, the determination flag described in step 106 in FIG. 3 is reset.
[0051]
Subsequently, in step 204, it is determined whether or not there is a stop notification from the in-vehicle terminal 40 that has transmitted the abnormality occurrence notification. Specifically, if the stop signal is received and the identification number included in the stop notification matches the identification number included in the abnormality occurrence notification, the determination is affirmative. Otherwise, the determination is negative. Is determined. Note that the stop signal is data indicating that it is requested to stop the alarm sound generation of the alarm device 9 based on the occurrence of abnormality, which is transmitted from another in-vehicle terminal 40 as will be described later.
[0052]
When it determines with affirmation at step 204, a process progresses to step 206, a control signal is output to the alarm device 9, and the action | operation of the alarm device 9 is stopped. As a result, the alarm device 9 stops emitting an alarm sound.
[0053]
When it determines with negative by step 204, a process progresses to step 205 and determines whether the operation time of the alarm apparatus 9 is less than regulation time T2. Specifically, it is determined whether or not an interrupt signal has been input from the timer unit 7 after the process of step 203, based on whether or not the flag reset in step 203 is set. If this determination is negative, the process returns to step 204; if the determination is positive, the process proceeds to step 206.
[0054]
Following the alarm stop process in step 206, the process returns to step 200.
[0055]
The in-vehicle terminal 40 that has received the abnormality notification by the processing of FIG. 4 as described above (see step 200) transmits the abnormality notification when the distance between the two vehicles is equal to or less than the notification distance included in the abnormality notification (see step 201). A response notification is returned to the origin (see step 202), and the alarm device 9 is activated (see step 203). Then, when there is a stop notification from the transmission source (see step 204), or when the operating time of the alarm device 9 has passed the specified time (see step 205), the alarm device 9 is stopped (step 206).
[0056]
FIG. 5 shows a program for processing when the in-vehicle terminal 40 of the vehicle receives an operation for stopping the alarm sound generation by the user after transmitting the abnormality notification. Hereinafter, the program of FIG. 5 will be described.
[0057]
First, when the process is started, it is determined in step 300 whether or not there has been a stop operation by the user, and this determination process is repeated until this operation is performed. Whether or not there is a stop operation is determined by whether or not a signal output from the operation switch unit 8 is received when the user performs a predetermined stop operation on the operation switch unit 8.
[0058]
If there is a stop operation, the process proceeds to step 301, where stop notification data is created, and this stop notification is output to the wireless communication unit 2 for transmission to the surroundings of the host vehicle at a predetermined frequency. The stop notification is data indicating that the alarm sound generation of the alarm device 9 based on the occurrence of abnormality is requested to be stopped. Specifically, the stop notification includes data indicating the stop notification, an identification number of the in-vehicle terminal 40 that transmits the stop notification stored in the ROM, and the like.
[0059]
In step 302, a control signal is output to the alarm device 9 to stop the operation of the alarm device 9. As a result, the alarm device 9 stops emitting an alarm sound.
[0060]
An operation example of the above-described configuration and operation abnormality notification system will be described with reference to FIG. First, (1) When an abnormality occurs in the vehicle A, (2) the in-vehicle terminal 40 of the vehicle A that detects the abnormality transmits an abnormality occurrence notification to the surroundings. Then, the vehicle B and the vehicle A that have received the abnormality occurrence notification (3) activate the alarm device 9. (4) When the user of the vehicle A performs an operation to stop the alarm device 9, the alarm device 9 of the vehicle A stops, and (5) an alarm stop notification is transmitted from the vehicle A to the vehicle B. (6) In the vehicle B that has received the alarm stop notification, the alarm device 9 stops. In the vehicle B, the alarm device 9 may stop when a predetermined time has elapsed.
[0061]
With this configuration and operation, when the abnormality notification device 40 mounted on the vehicle detects an abnormality, an abnormality occurrence notification is transmitted. In addition, since the vehicle-mounted terminal 40 mounted on the vehicle around the vehicle activates the alarm sound generation device based on the reception of the abnormality occurrence notification, thereby the alarm sound generation device emits an alarm sound to the surroundings. Vehicles around the vehicle in which this occurs will also emit an alarm sound. Therefore, it is possible to remove the obstruction factors for notifying the occurrence of abnormality to the surroundings caused by notifying the surroundings of the occurrence of abnormality by the alarm device alone.
[0062]
Further, the abnormality occurrence notification includes information on the current position of the vehicle and the notification distance, and the in-vehicle terminal 40 on the receiving side calculates the distance between the two vehicles based on the current position information and the current position information of the own vehicle. When the distance between the two vehicles is less than a predetermined value, the alarm device 9 is activated.

[0071]
Further, in the present embodiment, the information on the notification distance is included in the abnormality occurrence notification, and the notification distance is passed from the transmission source of the abnormality occurrence notification to the surrounding in-vehicle terminals 40, so that the in-vehicle terminal 40 on the receiving side is Whether or not to activate the alarm device 9 is determined based on this distance. However, this is not always necessary, and a value corresponding to the notification distance is set in advance in the ROM of the memory unit 6 of each in-vehicle terminal 40. When an abnormality notification is received, the notification distance is read, The operation of the alarm device 9 may be determined based on the read value.
