  As shown in FIG. 6, in the control flow of the tire information output program PG1, first, it is determined whether or not it is in the “output state” (that is, whether or not the tire information is being displayed on the display unit 23). (Step S1). If it is “output state” (Yes in step S1), the output flag is set to “0” (step S2), and the count of the power down timer is updated (step S3). Here, the power-down timer means a time required to automatically shift from the “output state” to the “non-output state”. By providing the power-down timer, the user can return from the “output state” to the “non-output state” without trouble. In addition, for a user who wants to confirm tire information output permanently during operation of the vehicle 80, in the example of the present embodiment, the “output state” is set to be maintained while the vehicle 80 is traveling.

  When the process of step S3 ends, it is then determined whether or not a signal has been received from the tire condition monitoring device 11 (step S4). Here, when there are a large number of vehicles 80 near the smartphone 20, the receiver 27 receives signals from a large number of tire condition monitoring devices 11, but the signal to be determined in step S4. Is only a signal from the tire condition monitoring device 11 whose ID is registered in the smartphone 20.

  When the signal from the tire condition monitoring device 11 is not received (No in Step S4), it is determined whether or not the power down timer has elapsed for 5 minutes or more (Step S5). If the power down timer is less than 5 minutes (No in step S5), the control flow ends. On the other hand, when the power down timer is 5 minutes or longer (Yes in step S5), a process of shifting to the “non-output state” is executed (step S6), and the power down timer is cleared (step S7). This control flow ends.

  If it is determined in step S4 that the signal from the tire condition monitoring device 11 has been received (Yes in step S4), the tire information output on the display unit 23 is updated (step S8), and the tire condition monitoring device is updated. It is determined whether or not the reception signal from 11 includes a “travel determination” signal (step S9). If there is a “travel determination” signal (Yes in step S9), the power-down timer is cleared (step S10), and this control flow ends. On the other hand, when there is no “running determination” signal (No in step S9), the control flow ends after the processes of steps S5 to S7 described above are executed.

  When it is determined in step S1 of the tire information output program PG1 that it is not “output state”, that is, “non-output state” (No in step S1), an output determination process (step S11) is executed. Is done. In the output determination process (step S11), it is determined whether or not the output condition set on the output condition setting screen G4A is satisfied. If the output condition is satisfied, the output flag is set to “1”, and the output condition is set. If not satisfied, the output flag remains “0”. Details of the output determination process (step S11) will be described later.

  When the output determination process (step S11) ends, it is then determined whether or not the output flag is “1” (step S12). When the output flag is “1” (Yes in step S12), a process of shifting to the “output state” is executed (step S13), and tire information is output on the display unit 23. Next, the automatic start enable / disable flag is set to “0”, the automatic start enable / disable timer is cleared (step S14), and this control flow ends. Note that the automatic startup permission / prohibition timer means the duration of the “non-output state”. As will be described later, if the automatic start enable / disable timer does not reach the predetermined time or more, it does not shift to the “output state” even if the output condition is satisfied. This is to prevent the user from shifting to the “output state” again because the output condition is satisfied immediately after the user has manually shifted to the “non-output state”.

  On the other hand, when the output flag is not “1”, that is, “0” (No in step S12), the count of the automatic start permission timer is updated (step S15), and the automatic start permission timer is set to 5 minutes. It is determined whether the above has elapsed (step S16). If the automatic start / stop timer is less than 5 minutes (No in step S16), the control flow ends. If the automatic startup availability timer is 5 minutes or longer (Yes in step S16), the automatic startup availability flag is set to “1” (step S17), and this control flow ends. Here, the automatic start enable / disable flag is for determining whether or not to automatically shift from the “non-output state” to the “output state”. When “0” is “0”, the automatic transition to the “output state” is prohibited, and when the automatic start enable / disable flag is “1”, the automatic transition to the “output state” is permitted.

  FIG. 7 shows details of the above-described output determination process (step S11). As shown in the figure, in the output determination process (step S11), it is first determined whether or not an output operation is manually performed by the user (step S21). When the output operation is performed manually (Yes in step S21), the output flag is set to “1” (step S22), and the process of step S23 is executed. If the output operation has not been performed manually (No in step S21), the process of step S23 is executed as it is.

  In the process of step S23, it is determined whether or not the automatic start permission flag is “1”. If the automatic startup permission flag is not “1”, that is, “0” (No in step S23), the output determination process (step S11) ends. When the automatic start permission flag is “1” (Yes in Step S23), it is determined whether or not a signal is received from the tire condition monitoring device 11 registered with ID (Step S24).

  If the ID is not received from the tire condition monitoring device 11 (No in step S24), the output determination process (step S11) ends. On the other hand, when receiving from the tire condition monitoring apparatus 11 registered with ID (Yes in step S24), whether or not the pressure of the tire 83 based on the reception signal from the tire condition monitoring apparatus 11 is less than the installation value. Is determined (step S25). When the pressure of the tire 83 is less than the set value (Yes in Step S25), the output flag is set to “1” (Step S26), and the vehicle vicinity process (Step S27) is executed. When the pressure of the tire 83 is equal to or higher than the set value (No in step S25), the vehicle vicinity process (step S27) is executed as it is.

  As shown in FIG. 8, in the vehicle vicinity process (step S27), first, it is determined whether or not the vehicle vicinity condition (see the output condition setting screen G4A in FIG. 4A) is set to ON in the output condition. (Step S31). When the vehicle vicinity condition is set to OFF (No in step S31), this vehicle vicinity process (step S27) is ended.

  If the vehicle vicinity condition is set to ON (Yes in step S31), it is determined whether or not there is an interval of 5 minutes or more between the current reception from the tire condition monitoring device 11 and the previous reception. (Step S32). If there is no interval of 5 minutes or more (No in step S32), the first reference value (for example, 20 dB) in which the change in the intensity of the received signal is preset in the tire condition monitoring device 11 registered in ID. It is determined whether or not there is a tire condition monitoring device 11 that is the above (step S35). If there is a tire condition monitoring device 11 in which the change in the intensity of the received signal is equal to or greater than the first reference value ( In step S35, the output flag is set to “1” (step S34), and the vehicle vicinity process (step S27) is ended. When there is no tire condition monitoring device 11 in which the change in the intensity of the received signal is equal to or greater than the first reference value (No in step S35), the vehicle vicinity process (step S27) is terminated as it is.

  In step S32, when there is an interval of 5 minutes or more between the current reception and the previous reception (Yes in step S32), the second reference value (for example, −60 dBm) in which the strength of the reception signal is set in advance is set. It is determined whether or not the above is true (step S33). If the intensity of the received signal is greater than or equal to the second reference value (Yes in step S33), the output flag is set to “1” (step S34), and this vehicle vicinity process (step S27) is terminated. When the intensity of the received signal is less than the second reference value (No in step S33), the vehicle vicinity process (step S27) is finished as it is.

  As described above, in the present embodiment, when the terminal control unit 21 executes the vehicle proximity process (step S27), the tire information is obtained when the smartphone 20 approaches the tire condition monitoring device 11 within a predetermined distance. Since it is output (see steps S11 to S13 in FIG. 6, steps S24 and S27 in FIG. 7, and step S34 in FIG. 8), the timing at which the user carrying the smartphone 20 gets on the vehicle 80 Thus, it is possible to output tire information of the wheels 81 provided in the vehicle 80.

  Further, when the receiver 27 receives a signal from the transmitter 13 without a certain time interval or more, when the change in the intensity of the received signal is equal to or greater than a predetermined first reference value. Since it is determined that the tire condition monitoring device 11 has come within a predetermined distance (see steps S32, S35, and S34 in FIG. 8), the user carrying the smartphone 20 does not have the intention to get on the vehicle. When staying near 80 parking spots for a long time, the tire information is prevented from being frequently output. Further, when the receiver 27 receives a signal from the tire condition monitoring device 11 with an interval of a certain time or more, even if the receiver 27 receives a signal from the tire condition monitoring device 11, the received signal If the strength of the vehicle is not equal to or greater than a predetermined second reference value, it is not determined that the vehicle has approached the tire condition monitoring device 11 within a predetermined distance (see the flow of steps S32 to S34 in FIG. 8). Frequent output of tire information is suppressed simply because an unintended user has passed near the parking spot of the vehicle 80.

  As shown in FIG. 7, when the vehicle vicinity process (step S27) ends, a registration point process (step S28) is then executed. When the registration point process (step S28) ends, the output determination process (S11) ends.

  FIG. 9 shows details of the registration point process (step S28). As shown in the figure, in the registration point process (step S28), first, it is determined whether or not the registration point condition (see the output condition setting screen G4A in FIG. 4A) is set to ON in the output condition. (Step S41). If the registration spot condition is set to OFF (No in step S41), the registration spot process (step S28) ends.

  If the registration spot condition is set to ON (Yes in step S41), it is determined whether or not a signal relating to stopping determination is received from the tire condition monitoring device 11 (step S42). If a signal related to the stop determination is received (Yes in step S42), a process (step S46) of acquiring data on the current position of the smartphone 20 from the GPS device 28 (see FIG. 2) is executed, and then the step is performed. The process of S43 is executed. On the other hand, when the signal regarding stop determination is not received (No in step S42), the process of step S43 is executed as it is.

  In the process of step S43, it is determined whether or not a signal relating to complete stop determination has been received from the tire condition monitoring device 11. If a signal relating to the complete stop determination is received (Yes in step S43), the smartphone 20 is next to the registration point registered in the output condition (see the point registration screen G4B in FIG. 4B). It is determined whether or not there is a current position (step S44). If the current position of the smartphone 20 is near the registration point (Yes in step S44), the output flag is set to “1”, and this registration point The process (step S28) ends. If a signal regarding complete stop determination has not been received (No in step S43), or if the current position of the smartphone 20 is not in the vicinity of the registration point (No in step S44), this registration point process (step S28) is performed as it is. ) Ends.

  As described above, in the present embodiment, the terminal control unit 21 executes the registration point process (step S28), so that the tire information is output when the current position of the smartphone 20 is in the vicinity of the registered point registered in advance. (See steps S11 to S13 in FIG. 6 and steps S44 to S45 in FIG. 9), when the user carrying the smartphone 20 gets on the vehicle 80 and reaches the registration point, the tire It is possible to output information. In particular, if a predetermined gas station or home is registered as a registration point, that is, if a place where there is a device (such as a compressor) that can maintain the tire 83 is registered as a registration point, the user can output the output tire. Based on the information, it is possible to know an appropriate time for maintenance of the tire 83, and it is possible to make a judgment such as performing maintenance on the spot.

  Further, when it is determined that the wheel 81 is stopped, the current position data of the smartphone 20 is acquired from the GPS device 28 (see the flow of steps S42 and S46 in FIG. 9). It becomes possible to reduce the load applied to the smartphone 20 as compared with the case of always acquiring the data. It is also possible to suppress malfunctions when the vehicle 80 passes the road adjacent to the registration point. Furthermore, in this embodiment, since the data of the current position of the smartphone 20 is acquired when the vehicle 80 is completely stopped, the vehicle 80 is waiting for a signal near the registration point. Even in this case, malfunction can be suppressed.

  The tire information output program PG1 executed by the terminal control unit 21 of the smartphone 20 has been described above. Note that the smartphone 20 when the signal from the tire condition monitoring device 11 is received by the receiver 27 corresponds to the “reception unit” of the present invention, and the terminal control unit 21 executes output determination processing (step S11). When the terminal 20 is executing the process of step S13, the smartphone 20 corresponds to the “tire information output unit” of the present invention.

  The description regarding the configuration of the tire information output system 10 according to the present embodiment and the tire information output program PG1 used in the smartphone 20 has been described above. Next, functions and effects of the tire information output system 10 and the tire information output program PG1 will be described.

  According to this embodiment, tire information is output when the terminal control unit 21 of the smartphone 20 determines that the output condition set on the output condition setting screen G4A is satisfied. According to this embodiment, it is possible to output tire information at a timing that the user wants to know by setting a condition desired by the user carrying the smartphone 20 as an output condition.

  Specifically, when the “location registration condition” is set on the output condition setting screen G4A, the user carrying the smartphone 20 gets on the vehicle 80 and stops at the registered location registered in the smartphone 20. Sometimes it is possible to output tire information. Further, when the “vehicle proximity condition” is set on the output condition setting screen G4A, the tire information of the wheels 81 provided in the vehicle 80 is output at the timing when the user carrying the smartphone 20 gets on the vehicle 80. It becomes possible to do. Furthermore, in this embodiment, since tire information is also output when the air pressure of the tire 83 falls below the set pressure (see steps S25 to S26 in FIG. 7), the abnormality of the tire 83 is notified to the user of the smartphone 20. It becomes possible to inform.

  Here, in this embodiment, when the “location registration condition” is set, when the terminal control unit 21 determines that the vehicle 80 is stopped, the GPS device 28 determines the current position of the smartphone 20. Since the data is acquired, it is possible to reduce the load on the smartphone 20 as compared to the case where the data of the current position of the smartphone 20 is always acquired. Further, it is possible to suppress malfunction when the vehicle 80 passes near the registration point.

  Further, in the present embodiment, when the “vehicle proximity condition” is set, when the receiver 27 receives a signal from the tire condition monitoring device 11 without an interval of a certain time or more, When the change in the intensity of the received signal is equal to or greater than a predetermined first reference value, it is determined that the tire condition monitoring device 11 is approaching within a predetermined distance, and the receiver 27 leaves an interval of a predetermined time or more. When the signal is received from the tire condition monitoring device 11, even if the receiver 27 receives the signal from the tire condition monitoring device 11, the intensity of the received signal is equal to or higher than a predetermined second reference value. Otherwise, it is not determined that the tire condition monitoring device 11 has come within a predetermined distance. Thereby, it is suppressed that tire information is frequently output to a user who does not desire tire information.
