[0029]
  The operation of the mobile communication apparatus configured as described above will be described below.
  First, the storage operation process of the CPU 5 in the vehicle 1 (the other vehicle B in this embodiment) that issues the request signal β will be described with reference to the flowchart of FIG.
[0030]
  In the first step U1, the CPU 5 determines whether or not the GPS signal is received every predetermined time, for example, every 5 seconds, based on the input from the GPS receiver 7, and skips to the fourth step U4 when determining NO. On the other hand, 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.
[0031]
  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. Transition.
  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.
[0032]
  The processes in the fifth and sixth steps U5 and U6 described above are autonomous in order to complement the GPS signal from the GPS satellite when it is not sufficiently obtained (for example, when traveling in a tunnel). Navigation 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.
[0033]
  Next, in the eighth step U8, the CPU 5 determines whether or not a predetermined time, for example, 1 minute has elapsed, and skips to the 14th step U14 when determining NO, while moving to the next ninth step U9 when determining YES. To do.
  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.
[0034]
  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, and proceeds to the thirteenth step U13 when determining NO, and next 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.
[0035]
  In the thirteenth step U13, the CPU 5 determines that there is no traffic jam, while 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.
[0036]
  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 fourteenth step U14, the CPU 5 determines whether or not the return signal (information signal α) set by the request signal β has been received. If YES, the CPU 5 skips to the sixteenth step U16, while NO. At the time of determination, the process proceeds to the next 15th step U15.
[0037]
  In the fifteenth step U15, the CPU 5 determines whether or not a transmission signal from another vehicle (this signal is a transmission signal from another vehicle not responding to the request signal) is received, and YES When the determination is made, the process proceeds to the 16th step U16, and when the determination is NO, the process proceeds to the 17th step U17.
[0038]
  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.
[0039]
  In short, the process in the flowchart of FIG. 7 is to update and store all received information in the RAM 21, and based on the sequentially updated data, for example, a traffic jam position b as indicated by a white arrow in FIG. The vehicle position a can be displayed visually.
  Next, with reference to the flowchart shown in FIG. 8, the signal return process on the information providing side (the vehicle A side) will be described.
[0040]
  In the first step S1, the CPU 5 determines whether or not the own vehicle A (see FIG. 4) has received the request signal β from the other vehicle B, 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 α. The process of the second step S2 will be described later with reference to a subroutine shown in FIG.
  Next, in the third step S3, the CPU 5 determines whether or not a reply is possible. When the determination is NO, the CPU 5 returns to the first step S1, while when the determination is YES, the CPU 5 proceeds to the next fourth step S4.
[0041]
  In the fourth step S4, the CPU 5 creates a return signal (information signal α). At the time of creation, if there is an ID stored in the RAM 21 in the request signal β (see the vehicle ID bit 23 in FIG. 5), the ID of the vehicle A (see the vehicle ID bit 34 in FIG. 6) is also returned. (Information signal α) is inserted.
[0042]
  Next, in the fifth step S5, the CPU 5 sets timing (return signal return timing) and strength (return signal electric field strength), respectively, and returns a return signal (information signal α) via the transmission circuit 4 and the antenna 2. To other vehicle B.
  Next, the flowchart shown in FIG.TheThe reply availability determination process will be described in detail with reference to FIG.
[0043]
  In the first step S11, the CPU 5 determines the current position and traveling direction of the own vehicle A from the RAM 21, and the current position, traveling direction, travel guideway, and travel direction of the travel guideway of the other vehicle B that has transmitted the request signal β. Read each one.
  Next, in the second step S12, the CPU 5 determines whether or not the request signal β from the other vehicle B includes traveling taxiway information (see bit = 1 in the route taxiway information bit 28 in FIG. 5), and YES. When the determination is made, the process skips to the eleventh step S21, while when the determination is NO, the process proceeds to the next third step S13.
[0044]
  In this third step S13, the CPU 5 determines from the current position and traveling direction of the other vehicle B and the current position of the own vehicle A to the traveling direction of the other vehicle B in the current position of the own vehicle A viewed from the other vehicle B. One offset angle θ1 (see FIG. 4) is calculated.
  Next, the fourth step S14, The CPU 5 determines that the first offset angle θ1 is a predetermined angle.,For example, it is determined whether or not the angle is smaller than 60 degrees. When NO is determined (when θ1> 60 °), the tenth step S10 is skipped, while when YES is determined (when θ1 <60 °), the next step is skipped. The process proceeds to 5 step S15.
[0045]
  In this fifth step S15 (comparison means), the CPU 5 compares the traveling direction of the host vehicle A with the traveling direction of the other vehicle B.
  Next, the sixth step S16The CPU 5 determines whether or not the angle difference between the traveling direction of the host vehicle A and the traveling direction of the other vehicle B is a predetermined value, for example, 60 degrees or less. While skipping to step S20, when YES is determined (when the angle difference is <60 °), the process proceeds to the next seventh step S17.
[0046]
  In this seventh step S17, the CPU 5 detects the arrival direction of the straight line L (see FIG. 4) from the other vehicle B to the own vehicle A from the current position of the own vehicle A and the current position of the other vehicle B.
  Next, in an eighth step S18, the CPU 5 determines, from the current position of the other vehicle B, the direction of arrival of the straight line L, and the direction of travel of the own vehicle A, the second offset angle θ2 ( (See FIG. 4).
[0047]
  Next, the ninth step S19The CPU 5 determines whether or not the above-described second offset angle θ2 is smaller than a predetermined angle, for example, 60 degrees. When NO determination is made (when θ2> 60 °), the process proceeds to the tenth step S20, while YES At the time of determination (when θ2 <60 °), the process proceeds to another 15th step S25.
  In the above-described tenth step S20 (corresponding to the prohibiting means), the CPU 5 determines that a reply is impossible, whereas in the fifteenth step S25, the CPU 5 determines that the reply is OK.
[0048]
  By the way, the eleventh step S described above.21The CPU 5 determines whether or not the host vehicle A is on the travel guidance path of the other vehicle B by route guidance. When NO is determined, the process proceeds to the above-described tenth step S20. When YES is determined, the process proceeds to the following twelfth step S22. To do.
[0049]
  This 12th step S22The CPU 5 determines whether or not the traveling direction of the own vehicle A is the same as the traveling direction of the traveling guidance path of the other vehicle B. When NO is determined, the process proceeds to the above-described tenth step S20. Control goes to step S23.
[0050]
  In this thirteenth step S23 (comparison means), the CPU 5 compares the traveling direction of the own vehicle A with the traveling direction of the other vehicle B, and the next fourteenth step S2324The CPU 5 determines whether or not the angle difference between these two traveling directions is a predetermined value, for example, 90 degrees or less.
[0051]
  When NO is determined (when the angle difference is greater than 90 °), the process proceeds to the tenth step S20. When YES is determined (when the angle difference is less than 90 °), the process proceeds to another fifteenth step S25. In the fifteenth step S25, the CPU 5 executes a determination that the response of the information signal α is acceptable.
[0052]
  In short, according to the mobile communication device of the above embodiment, the receiving means (refer to the antenna 2 and the receiving circuit 3) receives the request signal β including the state of the other vehicle B transmitted from the other vehicle B, and transmits it. The means (refer to the antenna 2 and the transmission circuit 4) transmits the information signal α, and the control means (refer to the CPU 5) transmits the above-described transmission means (when the reception means (refer to the antenna 2 and the reception circuit 3) receives the request signal β. The information signal α is transmitted to the antenna 2 and the transmission circuit 4).
[0053]
  Moreover, the own vehicle A isRequired from changes in vehicle speedTraffic jamNewsSelf-moving body information detecting means for detecting (refer to arithmetic unit 10) is provided, and prohibiting means (see transmission prohibiting processing unit 14) provided in the above-described control means (refer to CPU 5)Direction of travelAnd other car BCompared with the traveling direction, when it is detected that the traveling direction of the own vehicle A and the traveling direction of the other vehicle B are different,Information signal α(That is, traffic jam information)Prohibit sending.
  As a result, the unnecessary information signal α that causes noise can be regulated, and the necessary information can be obtained on the other vehicle B side. For example, the presence or absence of traffic congestion can be properly displayed on the other vehicle B side. can do.
[0054]
  Further, when it is detected by the comparison means (refer to the fifth step S15 in FIG. 9) for comparing the traveling direction of the own vehicle A and the traveling direction of the other vehicle B that the traveling directions of the two vehicles A and B are different. The prohibition means (see the transmission prohibition processing unit 14) prohibits the transmission of the information signal α.
  For this reason, when the traveling directions of the own vehicle A and the other vehicle B are different from each other (for example, when traveling in the opposite direction), the unnecessary information signal α is regulated to prevent noise, and the other vehicle There is an effect that necessary information can be reliably obtained on the B side.
[0055]
  Further, the above-described comparing means (see the fifth step S15 in FIG. 9) indicates that when the traveling directions of the vehicles A and B are different by a predetermined angle (60 degrees in this embodiment) or more, both traveling directions are different. Since the transmission of the information signal α by the prohibition means (see the transmission prohibition processing unit 14) is prohibited, the unnecessary information signal α is more effectively regulated to prevent noise and ensure acquisition of necessary information. There is an effect that can be performed.
[0056]
  Furthermore, the above-described prohibiting means (see the transmission prohibition processing unit 14) transmits the information signal α when the own vehicle A exists at a position other than a predetermined angle (60 degrees in this embodiment) with respect to the front of the other vehicle B. Ban. For this reason, there is an effect that the unnecessary information signal α can be regulated better, noise can be prevented, and necessary information can be obtained reliably.
[0057]
  In addition, the own vehicle A is provided with present location detecting means (refer to each element 7, 8, 9) for detecting the present location, and the prohibiting means (see the transmission prohibition processing unit 14) is configured so that the current location of the own vehicle A is the request signal β. When there is a route other than the route guide route based on the route guide route information of the other vehicle B included, the transmission of the information signal α is prohibited. Therefore, there is an effect that the information signal α that is useless for the other vehicle B is regulated, noise is prevented, and necessary information can be obtained with certainty.
[0058]
  Further, the above prohibiting means (see the transmission prohibition processing unit 14) is such that the current location of the host vehicle A is on the route guidance path based on the route guidance path information of the other vehicle B, and the comparison means (see 13th step S23 in FIG. 9). When the traveling directions of the vehicles A and B are detected to be different from each other (for example, when traveling in the opposite lane), the transmission of the information signal α is prohibited. Therefore, there is an effect that unnecessary information signals can be regulated with high accuracy, noise can be prevented, and necessary information can be obtained reliably.
[0059]
  Further, the comparison means (see the thirteenth step S23 in FIG. 9) is configured so that when the current location of the vehicle A is on the route guidance route according to the route guidance route information of the other vehicle B, When the traveling direction of the host vehicle A is different, it is determined that the traveling directions are different. In this case, the prohibiting means (see the transmission prohibiting processing unit 14) prohibits the transmission of the information signal α. For this reason, there is an effect that unnecessary information signals can be regulated with higher accuracy, noise can be prevented, and necessary information can be obtained reliably.
[0060]
  Furthermore, the above-mentioned prohibition means (see the transmission prohibition processing unit 14) is such that the traveling direction of the own vehicle A is changed from the current location of the other vehicle B (this information is included in the request signal β) to the current location of the own vehicle A. When the angle is other than a predetermined angle (60 degrees in this embodiment) with respect to the direction of the straight line L (see FIG. 4), the transmission of the information signal α is prohibited. For this reason, there is an effect that the unnecessary information signal α can be more strictly regulated, noise can be prevented, and necessary information can be reliably obtained.
