Here, the power down timer means the time taken to automatically shift from the "output state" to the "non-output state". Note that by providing the power down timer, the user can return from the "output state" to the "non-output state" without any trouble. Further, for the user who wants to permanently confirm the tire information output while driving the vehicle 80, in the example of the present embodiment, the "output state" is set while the vehicle 80 is traveling.

  When the process of step S3 is completed, it is then determined whether a signal has been received from the tire condition monitoring device 11 (step S4). Here, when there are many vehicles 80 near the smartphone 20, the receiver 27 will receive signals from many tire condition monitoring devices 11, but the signal to be judged in step S4 These are only signals from the tire condition monitoring device 11 whose ID is registered in the smartphone 20.

  If the signal from the tire condition monitoring device 11 is not received (No in step S4), it is determined whether 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), this control flow ends. On the other hand, if the power down timer is 5 minutes or more (Yes in step S5), processing to shift 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 is received (Yes in step S4), the tire information output from the display unit 23 is updated (step S8), and the tire condition monitoring device It is determined whether or not there is a signal of "travel determination" in the received signal from 11 (step S9). Then, when there is a signal of "travel determination" (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 signal of "travel determination" (No in step S9), after the process of steps S5 to S7 described above is executed, this control flow ends.

  In the process of step S1 of the tire information output program PG1, when it is determined not to be the "output state", that is, it is determined to be the "non-output state" (No in step S1), the output determination process (step S11) is executed. Be done. In the output determination process (step S11), it is determined whether or not the output condition set in 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 displayed. If not satisfied, the output flag remains "0". The detailed description of the output determination process (step S11) will be described later.

  When the output determination process (step S11) is completed, it is then determined whether the output flag is "1" (step S12). When the output flag is “1” (Yes in step S12), processing for shifting to the “output state” is executed (step S13), and the tire information is output from the display unit 23. Next, the automatic start-up enable / disable flag is set to "0" and the automatic start-up enable / disable timer is cleared (step S14), and this control flow ends. The automatic start-up / off timer means the duration of the "non-output state". As described later, if the automatic start-up / off timer has not reached a predetermined time or more, the state does not shift to the “output state” even if the output condition is satisfied. This is to prevent transition to the “output state” again by satisfying the output condition immediately after the user has shifted to the “non-output state” by the manual operation.

  On the other hand, if the output flag is not "1", that is, it is "0" (No in step S12), the count of the automatic startup availability timer is updated (step S15), and the automatic startup availability timer is 5 minutes. It is determined whether the above has elapsed (step S16). If the automatic startup enable / disable timer is less than 5 minutes (No in step S16), this control flow ends as it is. If the automatic startup availability timer is 5 minutes or more (Yes in step S16), the automatic startup availability flag is set to "1" (step S17), and this control flow ends. Here, the automatic startup enable / disable flag is for determining whether or not to shift to the “output status” automatically from the “non-output status”, and the automatic startup enable / disable flag When “0” is “0”, the transition to the “output state” is prohibited, and when the automatic start-up possibility flag is “1”, the 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 the user has manually performed an output operation (step S21). When the output operation has been performed manually (Yes in step S21), the output flag is set to "1" (step S22), and the process of step S23 is performed. When the output operation has not been performed manually (No in step S21), the process of step S23 is performed as it is.

  In the process of step S23, it is determined whether or not the automatic startup enable / disable flag is "1". If the automatic startup enable / disable flag is not "1", that is, it is "0" (No in step S23), the output determination process (step S11) ends. If the automatic launch enable / disable flag is "1" (Yes in step S23), it is determined whether a signal has been received from the tire condition monitoring device 11 whose ID has been registered (step S24).

  When not received from the tire condition monitoring device 11 in which the ID is registered (No in step S24), the output determination process (step S11) is ended. On the other hand, if it is received from the tire condition monitoring device 11 whose ID is registered (Yes in step S24), whether the pressure of the tire 83 based on the reception signal from the tire condition monitoring device 11 is less than the installation value Is determined (step S25). If 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 proximity process (step S27) is performed. When the pressure of the tire 83 is equal to or higher than the set value (No in step S25), the vehicle proximity process (step S27) is performed as it is.

  As shown in FIG. 8, in the vehicle proximity process (step S27), it is first determined whether the vehicle proximity condition (see the output condition setting screen G4A in FIG. 4A) is set to ON under the output condition. (Step S31). When the vehicle vicinity condition is set to OFF (No in step S31), the vehicle vicinity processing (step S27) is ended.

  When 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). When 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 strength of the received signal is preset in the tire condition monitoring device 11 whose ID is registered. It is judged whether or not there is a tire condition monitoring device 11 having the above condition (step S35). If there is a tire condition monitoring device 11 in which the change in the intensity of the received signal is greater than the first reference value ( In step S35, the output flag is set to "1" (step S34), and the vehicle proximity processing (step S27) is ended. When there is not one tire condition monitoring device 11 whose change in strength of the received signal is equal to or more than the first reference value (No in step S35), the vehicle proximity processing (step S27) is ended 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), a second reference value (for example, -60 dBm) in which the strength of the received signal is preset. ) Is judged (step S33). If the strength of the received signal is equal to or greater than the second reference value (Yes in step S33), the output flag is set to "1" (step S34), and the vehicle proximity processing (step S27) is ended. When the strength of the received signal is less than the second reference value (No in step S33), the vehicle proximity processing (step S27) is ended as it is.

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

  Also, in the case where the receiver 27 receives the signal from the transmitter 13 without an interval of a predetermined time or more, when the change in the strength of the received signal is equal to or more than a predetermined first reference value Since it is determined that the user approaches the tire condition monitoring device 11 within a predetermined distance (see the flow of steps S32, S35, and S34 in FIG. 8), the user carrying the smartphone 20 does not have an intention to get on the vehicle. When staying for a long time near 80 parking points, frequent output of tire information is suppressed. Furthermore, when the receiver 27 receives a signal from the tire condition monitoring device 11 at intervals of a predetermined time or more, even if the receiver 27 receives a signal from the tire condition monitoring device 11, the received signal is Since it is not determined that the tire condition monitoring device 11 has approached within the predetermined distance unless the strength of the vehicle is equal to or greater than a predetermined second reference value (see the flow of steps S32 to S34 in FIG. 8) Frequent output of tire information is suppressed only by the intentional user passing near the parking point of the vehicle 80.

  As shown in FIG. 7, when the vehicle proximity process (step S27) is completed, then a registration point process (step S28) is executed. When the registration point process (step S28) is finished, the output judgment process (S11) is finished.

  The details of the registration point process (step S28) are shown in FIG. As shown in the figure, in the registration point process (step S28), it is first determined whether the registration point condition (see the output condition setting screen G4A in FIG. 4A) is set to ON in the output condition. (Step S41). When the registration point condition is set to off (No in step S41), the registration point processing (step S28) is ended.

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

  In the process of step S43, it is determined whether the signal regarding the complete stop determination is received from the tire condition monitoring device 11. If the signal related to the complete stop determination has been received (Yes in step S43), then, the smartphone 20 of the vicinity of the registration point (see the point registration screen G4B in FIG. 4B) registered in the output condition It is determined whether or not the current position is present (step S44), and when the current position of the smartphone 20 is present 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 the signal related to the complete stop determination has not been received (No at Step S43) or if the current position of the smartphone 20 is not present near the registration point (No at Step S44), this registration point processing (Step S28) ) Ends.

  As described above, in the present embodiment, the terminal control unit 21 executes the registration point processing (step S28) to output tire information when the current position of the smartphone 20 is in the vicinity of the registration 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 becomes possible to output information. In particular, if a predetermined gas station or home is registered as a registration point, that is, if a location where equipment (such as a compressor) capable of maintaining the tire 83 is registered is registered as a registration point, the user can output the tire Based on the information, it is possible to know the appropriate time for maintaining 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, data of the current position of the smartphone 20 is acquired from the GPS device 28 (see the flow of steps S42 and S46 in FIG. 9). The load applied to the smartphone 20 can be reduced as compared with the case where the data of is constantly acquired. In addition, it is also possible to suppress a malfunction when the vehicle 80 passes the road next to the registration point. Furthermore, in the present 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. Also in the case, it becomes possible to suppress a malfunction.

  The description of the tire information output program PG1 executed by the terminal control unit 21 of the smartphone 20 is as described above. The smartphone 20 when the signal from the tire condition monitoring device 11 is received by the receiver 27 corresponds to the “receiving unit” of the present invention, and the terminal control unit 21 executes the output determination process (step S11). The smartphone 20 at the same time corresponds to the “determination unit” of the present invention, and the smartphone 20 at the time when the terminal control unit 21 executes the process of step S13 corresponds to the “tire information output unit” of the present invention.

  The description regarding the structure of tire information output system 10 which concerns on this embodiment, and tire information output program PG1 used for the smart phone 20 is above. Next, the effects of the tire information output system 10 and the tire information output program PG1 will be described.

  According to the present embodiment, tire information is output when the terminal control unit 21 of the smartphone 20 determines that the output condition set in the output condition setting screen G4A is satisfied. According to the present embodiment, it is possible to output the tire information at the timing that the user wants to know by setting the conditions desired by the user who carries the smartphone 20 as the output conditions.

  Specifically, when “point registration condition” is set in the output condition setting screen G4A, the user carrying the smartphone 20 gets on the vehicle 80 and stops at the registration point registered in the smartphone 20 Sometimes, it becomes possible to output tire information. In addition, when “vehicle vicinity condition” is set in 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 is possible to Furthermore, in the present embodiment, even when the air pressure of the tire 83 falls below the set pressure, tire information is output (see steps S25 to S26 in FIG. 7). It becomes possible to inform.

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

  Further, in the present embodiment, when the “near-vehicle condition” is set, when the receiver 27 receives a signal from the tire condition monitoring device 11 without leaving an interval of a predetermined time or more, When the change in the strength of the received signal is greater than or equal to a predetermined first reference value, it is determined that the tire condition monitoring device 11 has come within a predetermined distance, and the receiver 27 opens a predetermined time interval or more. If a signal is received from the tire condition monitoring device 11, even if the receiver 27 receives a signal from the tire condition monitoring device 11, the intensity of the received signal is equal to or greater than a predetermined second reference value. If not, it is not determined that the tire condition monitoring device 11 has approached within the predetermined distance. This suppresses frequent output of tire information to a user who does not want tire information.
