[0039]
The operation of the mobile communication apparatus configured as described above will be described below.
First, the storage operation processing of the CPU 5 in the vehicle A that issues the request signal α will be described with reference to the flowchart of FIG. In this case, the vehicle A shown in FIG. 4 becomes the own moving body (own vehicle), and the vehicle B becomes the other moving body (other vehicle).
[0040]
In the first step U1, the CPU 5 determines whether or not the GPS signal is received at predetermined time intervals, for example, every 5 seconds, based on the input from the GPS receiver 7, and skips to the fourth step U4 when determining NO. When YES is determined, the process proceeds to the next second step U2.
In the second step U2, the CPU 5 calculates the current position from the received GPS signal, and in the next third step U3, the CPU 5 stores the calculated current position in the RAM 21.
[0041]
Next, in the fourth step U4, the CPU 5 determines whether or not a predetermined short time, for example, 3 seconds has elapsed, and skips to the eighth step U8 when determining NO, while moving to the next fifth step U5 when determining YES. .
In the fifth step U5, the CPU 5 calculates the vehicle speed V by the input from the vehicle speed sensor 9, and in the next sixth step U6, the CPU 5 calculates the traveling direction by the input from the gyro 8.
[0042]
The processing in the fifth and sixth steps U5 and U6 described above is an autonomous navigation system that complements the GPS signal from the GPS satellite when it is not sufficiently obtained (for example, when traveling in a tunnel). It is processing.
Next, in a seventh step U7, the CPU 5 obtains the current position from the vehicle speed V and the traveling direction as the above calculation result, and stores the three of the vehicle speed V, the traveling direction and the current position in the RAM 21.
[0043]
Next, in the eighth step U8, the CPU 5 determines whether or not a predetermined time, for example, one minute has elapsed, and skips to the fourteenth step U14 when determining NO, while moving to the next ninth step U9 when determining YES.
In the ninth step U9, the CPU 5 determines whether or not the vehicle speed V is, for example, 1.5 km / h or less. When NO is determined, the process proceeds to the thirteenth step U13, and when YES is determined, the process proceeds to the next tenth step U10.
[0044]
In this tenth step U10, the CPU 5 determines whether or not the determination of V <1.5 Km / h has continued for a predetermined number of times, for example, five times or more, proceeds to the thirteenth step U13 when determining NO, and proceeds to the next step when determining YES. The process proceeds to the eleventh step U11. In addition, since the error may possibly be included in the determination by the predetermined value 1.5 km / h and 5 times in the ninth and tenth steps U9 and U10, smoothing control is applied.
[0045]
In the thirteenth step U13, the CPU 5 determines that there is no traffic jam. On the other hand, in the eleventh step U11, the CPU 5 determines whether or not the determination of V <1.5 km / h is a predetermined number of times, for example, five times. That is, the process in the eleventh step U11 is for facilitating the process. When NO is determined in the eleventh step U11 (for example, when it is six or more consecutive times), the process skips to the fourteenth step U14, and when YES is determined, the process proceeds to the next twelfth step U12.
[0046]
In this twelfth step U12, the CPU 5 determines that there is a traffic jam and stores it in the RAM 21 in response to the determination that V <1.5 Km / h is continued five times. That is, it corresponds to setting the traffic jam bit 37 in FIG.
Next, in the 14th step U14, the CPU 5 determines whether or not the return signal (information signal β) set by the request signal α is received, and skips to the 16th step U16 when determining YES, while determining NO. Sometimes the process moves to the next 15th step U15.
[0047]
In this fifteenth step U15, the CPU 5 determines whether or not it has received a transmission signal from another vehicle (this signal is a transmission signal from another vehicle not responding to the request signal α), When YES is determined, the process proceeds to the 16th step U16, and when NO is determined, the process proceeds to the 17th step U17.
[0048]
In the 16th step U16 described above, the CPU 5 stores the data of the received signal in the RAM 21, and in the next 17th step U17, the CPU 5 determines whether or not there is data in the RAM 21 for a predetermined time, for example, 5 minutes or more. . When the determination is NO, the process returns. On the other hand, when the determination is YES, the process proceeds to the 18th step U18. In this 18th step U18, the CPU 5 clears the data in the RAM 21 more than 5 minutes ago.
[0049]
In short, the processing in the flowchart of FIG. 7 is to update and store all received information in the RAM 21. Based on the sequentially updated data, for example, the traffic position c as shown by the white arrow in FIG. The position a and the other vehicle position b can be displayed visually.
Next, the signal return process on the information providing side (vehicle B side) will be described with reference to the flowchart shown in FIG. In this case, the vehicle B shown in FIG. 4 becomes the own moving body (own vehicle), and the vehicle A becomes the other moving body (other vehicle).
[0050]
In the first step S1, the CPU 5 determines whether or not the own vehicle B (see FIG. 4) has received the request signal α from the other vehicle A and returns when determining NO, while returning to the next second step when determining YES. The process proceeds to S2.
In this second step S2, the CPU 5 determines whether or not to reply, that is, whether or not to return the information signal β.
Next, in the third step S3, the CPU 5 determines whether or not a reply is possible (OK). When NO is determined, the process returns to the first step S1, while when YES is determined, the process proceeds to the next fourth step S4.
[0051]
In the fourth step S4, the CPU 5 determines whether or not the received request signal α (see FIG. 5) includes the identification information previously folded, that is, the specific group ID code 23a shown in FIG.
When NO is determined (when the specific group ID code 23a is not included), the process proceeds to the fifth step S5. When YES is determined (when the specific group ID code 23a is included), another sixth step S5 is performed. The process proceeds to step S6.
[0052]
In the fifth step S5 described above, the CPU 5 creates a return signal, that is, the information signal β shown in FIG. 6, but in this case, the specific group ID code 34a is not folded.
On the other hand, in the above-described sixth step S6, the CPU 5 creates a return signal, that is, the information signal β shown in FIG.
[0053]
Next, in the seventh step S7, the CPU 5 sets timing (return signal return timing) and strength (return signal electric field strength), respectively, and sends a return signal (information signal β) via the transmission circuit 4 and the antenna 2. Return (send) to the other vehicle A.
Next, display processing on the transmission side of the request signal α, that is, the reception side of the information signal β will be described with reference to the flowchart shown in FIG. In this case, the vehicle A shown in FIG. 4 becomes the own moving body (own vehicle), and the vehicle B becomes the other moving body (other vehicle).
At the first step S11, the CPU 5 sends a request signal α to the other vehicle B (only one other vehicle B is shown in FIG. Is transferred to the next second step S12 only when YES is determined.
[0054]
In this second step S12, the CPU 5 determines whether or not a predetermined time has elapsed (the time that the request signal α reaches the other vehicle B and the information signal β returns from the other vehicle B), and the determination is YES. Only at times does the process shift to the next third step S13.
In the third step S13, the CPU 5 determines whether or not a response signal from the other vehicle B (information signal β corresponding to the request signal α) has been received. Specifically, as described in the flowchart of FIG. 7, since all of the received signals are stored in a predetermined area of the RAM 21 (see the 16th step U16), the information signal β is stored in the RAM 21 in the third step S13. When it is determined NO, the process proceeds to the next fourth step S14, and when it is determined YES, the process proceeds to another fifth step S15.
[0055]
In the above-described fourth step S14, the CPU 5 displays on the screen of the LCD 18 that there is no response signal (information signal β) in the area, for example, by characters or marks, and then returns to the first step S11.
On the other hand, in the above-described fifth step S15, the CPU 5 calculates a region (congested region) that is considered to be congested from the current position, vehicle speed, and traffic jam information (see the traffic jam bit 37) of the information signal β stored in the RAM 21.
[0056]
Next, in a sixth step S16, the CPU 5 displays the congestion area on the map, for example, in red (see the congestion position c indicated by the white arrow in FIG. 3).
Next, in a seventh step S17, the CPU 5 determines whether or not the specific group ID code 34a (see FIG. 6) is included in the information signal β as a response signal. If NO is determined, the process returns to the first step S11. If YES is determined, the process proceeds to the next eighth step S18.
[0057]
In the eighth step S18, the CPU 5 reads the ID code stored in advance in the RAM 21, and in the next ninth step S19, the CPU 5 identifies one of the plurality of ID codes read from the RAM 21 and the information signal β. It is determined whether or not the group ID code 34a matches each other. That is, double determination is executed in the seventh step S17 and the ninth step S19 described above, and a more accurate determination as to whether or not a specific group is made by such a two-stage check function.
[0058]
Thus, when NO is determined in the ninth step S19 described above (when it is determined that there is a mismatch), the process returns to the first step S11, while when YES is determined (when it is determined that there is a match). Shifts to the next tenth step S20.
In the tenth step S20, the CPU 5 displays on the LCD 18 the current position, vehicle speed, and traveling direction of the other vehicle B (that is, the fellow vehicle) that has returned the response signal (information signal β) including the specific group ID code 34a. (Refer to other vehicle position b in FIG. 3).
[0059]
Instead of the configuration using the specific group ID code 34a described above, a flag for identifying a specific group may be used. That is, in the sixth step S6 of the flowchart shown in FIG. 8, a flag indicating a specific group is set in place of the process of folding a predetermined code when the return signal β is created (F = 1), and the flowchart shown in FIG. If it is configured to determine whether F = 1 in the seventh step S17, control can be facilitated.
[0060]
In short, according to the mobile communication device of the above embodiment, the receiving means (refer to the antenna 2 and the receiving circuit 4) is transmitted from the other mobile body (the other vehicle A). Upon receiving the request signal α, the transmission means (refer to the antenna 2 and the transmission circuit 4) transmits the information signal β of the own mobile body (the own vehicle B) to the other mobile body (the other vehicle A), and the control means (refer to the CPU 5). When the receiving means (refer to the antenna 2 and the receiving circuit 4) receives the request signal α, the transmitting means (refer to the antenna 2 and the transmitting circuit 4) transmits the information signal β, but the control means (refer to the CPU 5) When the detection means (see the fourth step S4 in FIG. 8) detects that the identification information (see the specific group ID code 23a) is included in the request signal α, the information signal β is added to the information signal β in the sixth step S6. Predetermined recognition information ( If the detection means (see the fourth step S4) detects that the identification information (see the specific group ID code 23a) is not included in the request signal α, In the fifth step S5, predetermined recognition information (see the specific group ID code 34a) is transmitted without being inserted into the information signal β.
As a result, even in unspecified vehicle-to-vehicle communication, the current position of a specific vehicle is identified based on the identification information (such as ID) in the request signal α and the predetermined recognition information (such as code) in the information signal β. There is an effect that can.
