Description

Tire condition sensing method and system

The present invention relates to a tire condition sensing method, in particular to a tire condition sensing method suitable for sensing the tire pressure of a vehicle. The present invention also relates to a tire condition sensing system capable of implementing the tire condition sensing method.

The following is an exemplary detailed description of how the tire condition sensing system 1 of the present embodiment implements a tire condition sensing method.

In this embodiment, the tire condition sensing method includes, for example, a tire condition transmission part and an abnormality detection part. Referring to FIGS. 1 to 3 at the same time, the following first describes how the tire condition sensing system 1 executes the tire condition transmission part of the tire condition sensing method.

First, in step S11, the processing unit 12 outputs a sensing command by wireless transmission. In this embodiment, the sensing command, for example, indicates the main sensor a1 and the main sensor b1, and is used for wireless transmission by the main sensor a1 and the main sensor b1, for example. way to receive. Next, the flow proceeds to step S12 and step S13 at the same time, for example.

In step S12, after the main sensor a1 receives the sensing command by wireless transmission, the first sensing unit 11A executes a sensing procedure. Moreover, for the convenience of the subsequent description, the sensing procedure performed by the first sensing unit 11A is herein referred to as a first sensing procedure of the present embodiment.

Specifically, when the first sensing unit 11A executes the first sensing procedure, the main sensor a1 will sense the tire m1 corresponding to itself according to the sensing instruction to generate a Corresponds to the tire condition information of the tire m1. In addition, the master sensor a1 will also output an indication of the slave sensor a2 and the slave sensor a3 by wireless transmission according to the sensing command for the slave sensor a2 and the slave sensor a3. The first control command received by the sensor a3 by wireless transmission.

Next, after the slave sensor a2 receives the first control command by wireless transmission, the slave sensor a2 senses the tire m2 corresponding to itself according to the first control command to generate a The tire condition data corresponding to the tire m2 is outputted by wireless transmission for the main sensor a1 to receive.

On the other hand, after the slave sensor a3 receives the first control command by wireless transmission, the slave sensor a3 senses the tire m3 corresponding to itself according to the first control command A pair of tire condition data corresponding to the tire m3 is generated, and the tire condition data corresponding to the tire m3 is output by wireless transmission for the main sensor a1 to receive.

In addition, the tire condition data corresponding to the tire m1 is generated at the master sensor a1, and the data generated by the slave sensor a2 and the slave sensor a3 and corresponding to the tire are also received by wireless transmission. After the two tire condition data of the tire m2 and the tire m3, the main sensor a1 will output the three tire condition data corresponding to the tire m1, the tire m2 and the tire m3 in a wireless transmission manner to For the processing unit 12 to receive and obtain the three pieces of tire condition data corresponding to the tire m1, the tire m2 and the tire m3. Moreover, in this embodiment, the main sensor a1 may, for example, first generate an integrated data, and the integrated data includes the three tire condition data corresponding to the tire m1, the tire m2, and the tire m3, respectively, Next, the main sensor a1 outputs the integrated data in a wireless transmission manner for the processing unit 12 to receive and obtain the three tire condition data corresponding to the tire m1 , the tire m2 and the tire m3 . However, in other embodiments, the main sensor a1 may also sequentially output the three pieces of tire condition data respectively corresponding to the tire m1 , the tire m2 and the tire m3 one by one for the processing unit 12 to receive, but is not limited to this embodiment.

In this way, although the slave sensor a2 and the slave sensor a3 are far apart from the processing unit 12, through the first sensing procedure, the master sensor a1 can The sensor a2 and the two tire condition data generated and output from the sensor a3 are then output by wireless transmission for the processing unit 12 to receive. In other words, in addition to outputting the tire condition data (that is, the tire condition data corresponding to the tire m1 ) generated by the main sensor a1 for the processing unit 12 to receive, the main sensor a1 can also replace the The slave sensor a2 and the slave sensor a3 output the two pieces of tire condition data respectively corresponding to the tire m2 and the tire m3 for the processing unit 12 to receive. Therefore, even if the processing unit 12 is far away from the slave sensor a2 and the slave sensor a3 and cannot directly communicate wirelessly with the slave sensor a2 and the slave sensor a3, the processing unit 12 The two pieces of tire condition data corresponding to the tire m2 and the tire m3 can still be received through the main sensor a1.

In step S13, after the main sensor b1 receives the sensing instruction by wireless transmission, the second sensing unit 11B executes another sensing procedure. Moreover, for the convenience of the subsequent description, the sensing procedure performed by the second sensing unit 11B is herein referred to as a second sensing procedure of the present embodiment.

Specifically, when the second sensing unit 11B executes the second sensing procedure, the main sensor b1 will sense the tire m4 corresponding to itself according to the sensing instruction to generate a Corresponds to the tire condition information of the tire m4. Moreover, the master sensor b1 will also output an indication of the slave sensor b2 and the slave sensor b3 by wireless transmission according to the sensing command for the slave sensor b2 and the slave sensor b3. The second control command received by the sensor b3 in a wireless transmission manner.

Next, after the slave sensor b2 receives the second control command by wireless transmission, the slave sensor b2 senses the tire m5 corresponding to itself according to the second control command to generate a The tire condition data corresponding to the tire m5 is outputted by wireless transmission for the main sensor b1 to receive.

On the other hand, after the slave sensor b3 receives the second control command through wireless transmission, the slave sensor b3 senses the tire m6 corresponding to itself according to the second control command A pair of tire condition data corresponding to the tire m6 is generated, and the tire condition data corresponding to the tire m6 is output by wireless transmission for the main sensor b1 to receive.

In addition, the tire condition data corresponding to the tire m4 is generated at the master sensor b1, and the data generated by the slave sensor b2 and the slave sensor b3 and corresponding to the tire are also received by wireless transmission. After the two tire condition data of the tire m5 and the tire m6, the main sensor b1 will output the three tire condition data corresponding to the tire m4, the tire m5 and the tire m6 in a wireless transmission manner, to for the processing unit 12 to receive. Moreover, in this embodiment, the main sensor b1 may, for example, generate another integrated data first, and the integrated data includes the three tire conditions corresponding to the tire m4, the tire m5 and the tire m6 respectively Then, the main sensor b1 outputs the integrated data in a wireless transmission mode for the processing unit 12 to receive and obtain the three tires corresponding to the tire m4, the tire m5 and the tire m6 situation information. However, in other embodiments, the main sensor b1 may also sequentially output the three pieces of tire condition data respectively corresponding to the tire m4, the tire m5 and the tire m6 one by one for the processing unit 12 to receive, but is not limited to this embodiment.

Similar to the effect of the first sensing unit 11A executing the first sensing procedure, although the slave sensor b2 and the slave sensor b3 are far apart from the processing unit 12, the second Sensing procedure, the master sensor b1 can wirelessly transmit the two tire condition data after receiving the two tire condition data generated and output by the slave sensor b2 and the slave sensor b3 output for reception by the processing unit 12 . In other words, in addition to outputting the tire condition data (that is, the tire condition data corresponding to the tire m4) generated by the main sensor b1 for the processing unit 12 to receive, the main sensor b1 can also replace the The slave sensor b2 and the slave sensor b3 output the two pieces of tire condition data respectively corresponding to the tire m5 and the tire m6 for the processing unit 12 to receive. Therefore, even though the processing unit 12 is far away from the slave sensor b2 and the slave sensor b3 and cannot directly communicate wirelessly with the slave sensor b2 and the slave sensor b3, the processing unit 12 The two pieces of tire condition data corresponding to the tire m5 and the tire m6 can still be received through the main sensor b1.

In addition, in this embodiment, each tire condition data generated by the first sensing unit 11A and the second sensing unit 11B includes, for example, a tire pressure value and a unique identification code. The tire pressure value indicates the tire pressure of the tire 53 corresponding to the tire condition data. On the other hand, the identification code, for example, indicates the sensor that generates the tire condition data, and is used for the processing. The unit 12 identifies which sensor generates the tire condition data. In other words, the identification code is equivalent to allowing the processing unit 12 to identify which tire 53 of the vehicle 5 the tire condition data corresponds to. It should be noted that, in other embodiments, each sensor further includes a temperature sensing element, and each tire condition data may include, for example, a temperature value of the corresponding tire 53 , but this is not the case. limit.

In step S14, when the processing unit 12 receives the three pieces of tire condition data that are output by the main sensor a1 through wireless transmission and correspond to the tire m1, the tire m2 and the tire m3 respectively, and also receive When the three pieces of tire condition data corresponding to the tire m4, the tire m5 and the tire m6 are output by the main sensor b1 through wireless transmission, the processing unit 12, for example, will correspond to at least the six tires respectively. The tire pressure values of the six pieces of tire condition data of 53 are provided to the on-board computer system 52, so that the on-board computer system 52 can add the six tire pressure values to a tire pressure sensing record, or the six tire pressure values The tire pressure value is displayed for the user's reference, but not limited thereto.

It is worth mentioning that, in this embodiment, the period during which the first sensing unit 11A executes the first sensing procedure overlaps with the period during which the second sensing unit 11B executes the second sensing procedure, for example, Therefore, in order to prevent the first sensing unit 11A and the second sensing unit 11B from interfering with each other during the execution of the first sensing procedure and the second sensing procedure, the present embodiment uses, for example, frequency division multiplexing The first sensing unit 11A and the second sensing unit 11B each use different frequencies to output the tire condition data, but not limited to this connection technology (Frequency Division Multiple Access in English, FDMA for short) .

More specifically, in this embodiment, in step S1, the processing unit 12, for example, outputs the sensing command through a first channel corresponding to a first frequency range for the main sensor a1 and the main sensor a1 to output. The main sensor b1 receives.

In addition, during the process of the first sensing process being performed by the first sensing unit 11A, the main sensor a1 of the first sensing unit 11A is, for example, transmitted through a second frequency channel corresponding to a second frequency range. The first control command is output for the slave sensor a2 and the slave sensor a3 to receive, and the master sensor a1 is also received by the slave sensor a2 and the slave sensor a1, for example, through the second channel. The two tire condition data generated and output by the slave sensor a3 are respectively generated by the master sensor a1 itself, the slave sensor a2 and the slave sensor a3 through the second channel The three pieces of tire condition data are output for the processing unit 12 to receive.

On the other hand, when the second sensing unit 11B performs the second sensing procedure, the main sensor b1 of the second sensing unit 11B, for example, transmits a third frequency range corresponding to a third frequency range. channel and output the second control command for the slave sensor b2 and the slave sensor b3 to receive, and the master sensor b1 is also received by the slave sensor, for example, through the third channel The two tire condition data generated and output by b2 and the slave sensor b3, and the master sensor b1 itself, the slave sensor b2 and the slave sensor b3 are respectively separated through the third channel The generated three pieces of tire condition data are output for the processing unit 12 to receive.

More specifically, for example, the first frequency range, the second frequency range and the third frequency range can be respectively implemented as 61kHz~64kHz, 65kHz~68kHz and 69kHz~72kHz in this embodiment, that is to say , the first frequency range to the third frequency range may, for example, be completely non-overlapping with each other. However, in other embodiments, the first frequency range to the third frequency range can also be implemented as non-overlapping aspects, for example, implemented as 60kHz-65kHz, 64kHz-69kHz, and 68kHz-73kHz, respectively. Generally speaking, as long as the first frequency range to the third frequency range are not completely overlapped or completely non-overlapping with each other, they belong to the embodiments of the present invention.

It should be added that, in this embodiment, the sensing instruction output by the processing unit 12 in step S11 includes, for example, a pair of first instruction parts corresponding to the main sensor a1 and a pair of corresponding main sensors The second instruction part of b1, wherein the first sensing unit 11A executes the first sensing procedure according to the first instruction part of the sensing instruction in step S12, and the second sensing unit 11B In step S13, for example, the second sensing procedure is executed according to the second command part of the sensing command. More specifically, for the first sensing unit 11A, the first instruction part of the sensing instruction in this embodiment, for example, indicates the complete operation steps of the first sensing procedure, however, in other embodiments , the complete operation steps of the first sensing procedure can also be pre-stored in the master sensor a1, the slave sensor a2 and the slave sensor a3, and the first command part of the sensing command It is only used as a trigger signal for triggering the first sensing unit 11A to start executing the first sensing procedure, and is not limited to this embodiment. On the other hand, the second instruction part of the sensing instruction in this embodiment, for example, indicates the complete operation steps of the second sensing procedure, and is similar to the first instruction part of the sensing instruction, so it is omitted here. To reiterate, however, in other embodiments, the second command part of the sensing command may only be used as a trigger signal to trigger the second sensing unit 11B to start executing the second sensing procedure, instead of the present implementation example is limited.

The above is an example description of the tire condition transmission part of the tire condition sensing method. It is added that the tire condition sensing system 1 can automatically execute the tire condition transmission part once when the vehicle 5 is started, for the on-board computer system 52 to initialize the vehicle 5 according to the tire condition data. detection program. Alternatively, the tire condition sensing system 1 may, for example, periodically execute the tire condition transmission part multiple times when the vehicle 5 is started, so that the on-board computer system 52 can perform the operation of the vehicle 5 according to the tire condition data. tire condition monitoring program.

Next, referring to FIG. 1 , FIG. 2 and FIG. 4 at the same time, the following describes how the tire condition sensing system 1 executes the abnormality detection part of the tire condition sensing method.

First, in step S21, for each of the master sensors 111 and the slave sensors 112 (hereinafter referred to as "the sensor"), the sensor corresponds to the tire corresponding to itself 53 performs sensing to obtain a tire pressure value corresponding to the tire 53 . Next, the flow proceeds to step S22.

In step S22, the sensor determines whether the tire pressure value is within a normal tire pressure range. If the result of the sensor's determination is yes, the process of the abnormality detection part ends. On the other hand, if The result of the sensor's judgment is no, and the process proceeds to step S23.

In step S23 following step S22, once the sensor determines that the tire pressure value is not within the normal tire pressure range, the sensor determines that an abnormal tire condition is met, and sends a pair of The abnormal notification of the abnormal tire condition is output by wireless transmission through a fourth channel corresponding to a fourth frequency range, and the fourth frequency range is, for example, the first frequency range to the third frequency range. Each does not completely or completely overlap each other.

It is particularly noted that, in this embodiment, the tire condition transmission part and the abnormality detection part of the tire condition sensing method are performed simultaneously by the tire condition sensing system 1 , for example, so by using the sensing method The detector outputs the abnormal notification through the fourth channel, which can prevent the abnormal notification from interfering with the first channel to the third channel.

Moreover, if the sensor is one of the main sensor a1 and the main sensor b1, the abnormal notification, for example, indicates the processing unit 12 for wireless transmission by the processing unit 12 way to receive directly. On the other hand, if the sensor is one of the slave sensor a2 and the slave sensor a3, the abnormal notification, for example, indicates the master sensor a1, which is used for the master sensor The sensor a1 receives, and, in this case, the main sensor a1 will output the abnormal notification by wireless transmission through the fourth channel for the processing unit 12 to receive when receiving the abnormal notification. On the other hand, if the sensor is one of the slave sensor b2 and the slave sensor b3, the abnormal notification, for example, indicates the master sensor b1, which is used for the master sensor The sensor b1 receives, and, in this case, the main sensor b1 outputs the abnormal notification by wireless transmission through the fourth channel for the processing unit 12 to receive when receiving the abnormal notification.

Next, the flow proceeds to step S24.

In step S24, when the processing unit 12 receives the abnormal notification, the processing unit 12 generates and outputs a warning notification for prompting the user according to the abnormal notification, and the warning notification, for example, indicates that the abnormal notification is generated. the sensor. Thereby, the warning notification can prompt the user that the tire 53 corresponding to the sensor has abnormal tire pressure. More specifically, in this embodiment, the processing unit 12 can output the warning notification through the on-board computer system 52, for example, and the warning notification can be implemented as a warning light indicating the tire 53 with abnormal tire pressure, for example No. However, in other embodiments, the processing unit 12 may also output the alert notification to the mobile phone of the user in the form of push broadcasting, for example, which is not limited to this embodiment.

The above is an example description of the abnormality detection part of the tire condition sensing method. It is added that, in a preferred embodiment, the tire condition sensing system 1 can execute the abnormality detection part of the tire condition sensing method when the vehicle 5 is turned on but not started.

It is added that, in this embodiment, the tire condition transmission part of the tire condition sensing method is, for example, used as a resident mechanism for tire condition sensing. However, in other embodiments, the tire condition transmission portion of the tire condition sensing method may also be used, for example, as a backup mechanism for tire condition sensing.

For example, in another embodiment, the tire condition sensing system 1 further includes a repeater (not shown), and the repeater is used for wireless The tire condition data output by the main sensors 111 and the slave sensors 112 are received by means of transmission, and then the tire condition data output by the main sensors 111 and the slave sensors 112 are received. The tire condition data is output by wireless transmission for the processing unit 12 to receive. However, when the processing unit 12 determines that the repeater is not functioning properly, the tire condition sensing system 1 will execute the tire condition sensing The tire condition transmission part of the detection method is used, so that the main sensors 111 can replace the function of the repeater.

The present invention also provides a second embodiment of the tire condition sensing system 1 , and the difference between the second embodiment and the first embodiment lies in the implementation of the tire condition transmission part of the tire condition sensing method .

Specifically, in the first embodiment, after the processing unit 12 outputs the sensing instruction in step S11 , the process proceeds to step S12 and step S13 simultaneously as shown in FIG. 3 , that is, in the first In an embodiment, the period during which the first sensing unit 11A executes the first sensing procedure overlaps with the period during which the second sensing unit 11B executes the second sensing procedure.

However, in the second embodiment, after the processing unit 12 outputs the sensing instruction in step S11 , the flow first proceeds to step S12 as shown in FIG. 5 , and the flow proceeds to step S12 after the end of step S12 Step S13. That is, in the second embodiment, the second sensing unit 11B may, for example, execute the second sensing procedure after the first sensing unit 11A finishes executing the first sensing procedure. In other words, in the second embodiment, the period during which the first sensing unit 11A executes the first sensing procedure and the period during which the second sensing unit 11B executes the second sensing procedure do not overlap with each other at all .

Taking FIG. 2 as an example, in the second embodiment, the main sensor a1 outputs the three pieces of tire condition data corresponding to the tire m1, the tire m2, and the tire m3 by wireless transmission. , is completely non-overlapping with the period during which the main sensor b1 outputs the three pieces of tire condition data corresponding to the tire m4, the tire m5 and the tire m6 respectively. In other words, the main sensor a1 and the main The sensor b1 uses, for example, time division multiple access (Time Division Multiple Access in English, TDMA for short) to output the tire condition data. More specifically, in the second embodiment, the sensing command output by the processing unit 12 includes, for example, the first command part corresponding to the main sensor a1 and the first command part corresponding to the main sensor b1 Two command parts, wherein, the first command part includes, for example, a pair of first return time (eg "8:00:00") corresponding to the main sensor a1 and later than the current time, and the second command part For example, it includes a pair of second return time corresponding to the main sensor b1 and later than the first return time (for example, "8:00:15"). And, in the second embodiment, the main sensor a1, for example, will correspond to the tire m1, the tire m2 and the tire m3 respectively when the first return time arrives in part according to the first command. The tire condition data is continuously output for a period of time (for example, 10 seconds) by wireless transmission for the processing unit 12 to receive. On the other hand, the main sensor b1 will, for example, partially correspond to the three tire condition data of the tire m4, the tire m5 and the tire m6 when the second return time arrives according to the second command. The output is continuously output for a period of time (eg, 10 seconds) in the manner of wireless transmission for the processing unit 12 to receive.

In this way, even if the tire condition sensing system 1 of the second embodiment does not use the frequency division multiple access technology, it can ensure that the first sensing unit 11A and the second sensing unit 11B are outputting the tire conditions The data will not interfere with each other, however, optionally, the tire condition sensing system 1 of the second embodiment can still utilize the frequency division multiple access technology as in the first embodiment.

The above is an illustration of the second embodiment of the present invention.

The present invention also provides a third embodiment of the tire condition sensing system 1. The third embodiment is similar to the second embodiment, and the difference between the third embodiment and the second embodiment is that the tire The implementation of the tire condition transmission part of the condition sensing method.

Referring to FIG. 6 in conjunction with FIG. 1 and FIG. 2 , the following exemplarily describes how the tire condition sensing system 1 of the third embodiment implements the tire condition transmission part of the tire condition sensing method.

First, in step S101, the processing unit 12 outputs a tire pressure report command by wireless transmission. In the third embodiment, the tire pressure reporting command, for example, indicates all the master sensors 111 and the slave sensors 112 , that is, the tire pressure reporting command in the third embodiment is, for example, For each of the master sensors 111 and the slave sensors 112 to receive by wireless transmission. It should be added that the processing unit 12 can be operated by, for example, the electric energy of the battery of the vehicle 6 without considering the problem of the battery life time. Therefore, compared with the master sensor 111 and the slave sensor 112 , the processing unit 12 can be set to perform wireless transmission with higher power and have a longer transmission distance, and it is assumed here that each of the master sensors 111 and the slave sensors 112 All of them can directly receive the tire pressure report command output by the processing unit 12 in a wireless transmission manner.

After the processing unit 12 outputs the tire pressure report command, the flow proceeds to step S102.

In step S102, for each of the master sensors 111 and the slave sensors 112 (hereinafter referred to as "the sensor"), when the sensor receives the tire through wireless transmission When the pressure report command is issued, the sensor senses the tire 53 it corresponds to to obtain a tire pressure value corresponding to the tire 53, and generates a tire condition data, wherein, for example, the tire condition data includes the The tire pressure value, and a pair of unique identification codes corresponding to the sensor itself. Next, the flow proceeds to step S103.

In step S103 , each of the master sensors 111 and the slave sensors 112 outputs the tire condition data generated by itself through wireless transmission for the processing unit 12 to receive. And, preferably, the master sensors 111 and the slave sensors 112 can respectively output the tire condition data by using at least one of frequency division multiple access technology and time division multiplexing technology. For example, in the aspect using the time-division multiplexing technology, the master sensors 111 and the slave sensors 112 can wirelessly transmit the tire condition data generated by themselves one by one, for example, in sequence. output for a period of time (for example, 5 seconds) in a manner of a The tire pressure report command output by the processing unit 12 indicates, but is not limited to, this. In the third embodiment, as shown in FIG. 2, since the slave sensor a2, the slave sensor a3, the slave sensor b2 and the slave sensor b3 are relatively far from the processing unit 12, Therefore, for the convenience of description, it is assumed here that the four pieces of tire condition data generated and output from the four sensors 112 cannot be directly received by the processing unit 12 , that is, the processing unit 12 is in step S103 Only the two tire condition data generated by the master sensor a1 and the master sensor b1 will be received, but not the slave sensor a2, the slave sensor a3, the slave sensor The sensor b2 and the four tire condition data generated from the sensor b3.

Next, the flow proceeds to step S104.

In step S104, when the processing unit 12 determines that a tire pressure reporting period corresponding to the tire pressure reporting command has ended, the processing unit 12 determines whether the master sensors 111 and the slave sensors 112 are received. The tire condition data generated by each of them. Wherein, the tire pressure reporting period is, for example, a period of time (eg, 30 seconds) since the processing unit 12 outputs the tire pressure reporting command. Moreover, since the processing unit 12 only receives the two pieces of tire condition data generated by the main sensor a1 and the main sensor b1 in step S103, the processing unit 12 in step S104, for example, It is determined that the tire condition data generated by the slave sensor a2, the slave sensor a3, the slave sensor b2 and the slave sensor b3 are not received. Next, the flow proceeds to step S11.

In step S11, the processing unit 12 outputs the sensing command by wireless transmission, and, similar to the second embodiment, the sensing command includes, for example, the first command part and the second command part, and the The first command part includes, for example, the first return time (eg, "8 hours, 0 minutes, 0 seconds") corresponding to the main sensor a1, and the second command part includes, for example, the time corresponding to the main sensor b1. The second return time is "8:00:15"). Further, in the third embodiment, since the processing unit 12 determines in step S104 that the tire condition data generated by the slave sensor a2 and the slave sensor a3 have not been received, the sensor The first command part of the test command, for example, further includes a tire condition data supplement request that indicates the slave sensor a2 and the slave sensor a3 and can be recognized by the master sensor a1. On the other hand, since the processing unit 12 determines in step S104 that the tire condition data generated by the slave sensor b2 and the slave sensor b3 have not been received, the second command of the sensing command For example, the part further includes a tire condition data supplement request that indicates the slave sensor b2 and the slave sensor b3 and can be recognized by the master sensor b1 .

It should be added that, in a preferred embodiment, if the processing unit 12 has received the tire condition data generated by the slave sensor a2 in step S103, but has not received the data from the slave sensor a3 If the tire condition data is generated, the tire condition data retransmission request of the first command part will, for example, only indicate the slave sensor a3, but not the slave sensor a2, that is, the first The tire condition data re-transmission request of a command part and the second command part, for example, only indicates the sensor corresponding to each tire condition data that the processing unit 12 should have received but did not receive in step S103, but Not limited to this.

After the processing unit 12 outputs the sensing instruction, the flow proceeds to step S12.

In step S12, the first sensing unit 11A executes the first sensing procedure according to the first command part of the sensing command, so that when the main sensor a1 arrives at the first return time (for example, reaches "" 8:00:00”), at least the two tire condition data generated by the slave sensor a2 and the slave sensor a3 (that is, the two tire conditions corresponding to the tire m2 and the tire m3 respectively) data) is output by wireless transmission for a period of time (for example, 10 seconds) for the processing unit 12 to receive. Next, the flow proceeds to step S13.

In step S13, the second sensing unit 11B executes the second sensing procedure according to the second command part of the sensing command, so that the main sensor b1 arrives at the second return time (for example, reaches " 8:0:15”), at least the two tire condition data generated by the slave sensor b2 and the slave sensor b3 (that is, the two tire conditions corresponding to the tire m5 and the tire m6 respectively) data) is output by wireless transmission for a period of time (for example, 10 seconds) for the processing unit 12 to receive. Next, the flow proceeds to step S14.

In step S14, the processing unit 12 at least receives the two tire condition data output by the main sensor a1 and corresponding to the tire m2 and the tire m3 respectively, and the data output by the main sensor b1 and After corresponding to the two tire condition data of the tire m5 and the tire m6 respectively, the processing unit 12 provides, for example, the six pieces of tire condition data corresponding to the two master sensors 111 and the four slave sensors 112 respectively. to the onboard computer system 52 .

It should be added that, in the first sensing procedure of the third embodiment, the difference from the first embodiment is that the master sensor a1 only needs to have the slave sensor a2 and the slave sensor a3 The two tire condition data generated can be output by wireless transmission for the processing unit 12 to receive, and it is not necessary to sense the tire m1 again to generate the tire condition data, and it is not necessary to re-sensing the main sensor. The tire condition data output corresponding to the tire m1 generated by the tester a1 itself. More specifically, in the first sensing procedure of the third embodiment, the main sensor a1 only needs to output the tire condition data not received by the processing unit 12 in step S103 . Similarly, in step S13, the master sensor b1 only needs to output the two tire condition data generated by the slave sensor b2 and the slave sensor b3 in a wireless transmission manner, and does not need to be re-transmitted. When the tire m4 is sensed to generate tire condition data, it is not necessary to output the tire condition data corresponding to the tire m4 generated by the main sensor b1 again.

The above is an illustration of the third embodiment of the present invention.

Referring to FIG. 7 and referring to FIG. 1 , the present invention also provides a fourth embodiment of the tire condition sensing system 1 , and the tire condition sensing system 1 of the fourth embodiment is suitable, for example, to be arranged in FIG. 7 . A vehicle 6 is shown.

Different from the first embodiment, the tire condition sensing system 1 of the fourth embodiment further includes a third sensing unit 11C in addition to the first sensing unit 11A and the second sensing unit 11B , wherein the third sensing unit 11C includes, for example, a master sensor 111 and two slave sensors 112 , and, for the convenience of description, the master sensor 111 of the third sensing unit 11C is taken as the first A master sensor c1 of the fourth embodiment, and the two slave sensors 112 of the third sensing unit 11C are respectively used as a slave sensor c2 and a slave sensor c3 of the present embodiment.

In addition, the vehicle 6 in which the tire condition sensing system 1 of the fourth embodiment is installed includes, for example, a vehicle body 61 , an in-vehicle computer system 62 , and twelve tires 63 arranged under the vehicle body 61 . The in-vehicle computer system 62 is, for example, disposed on a front part 611 of the vehicle body 61 , and the processing unit 12 of the fourth embodiment is also disposed in the front part 611 of the vehicle body 61 in this embodiment, and for example It is wired and electrically connected to the on-board computer system 62, but is not limited to this.

For the convenience of description, the nine tires 63 of the vehicle 6 are referred to as one tire m1, one tire m2, one tire m3, one tire m4, one tire m5, one tire m6, one tire shown in FIG. m7, one tire m8 and one tire m9.

Similar to the first embodiment, the master sensor a1 , the slave sensor a2 and the slave sensor a3 of the first sensing unit 11A are respectively disposed on the tire m1 , the tire m2 and the The tire m3, and the master sensor b1, the slave sensor b2 and the slave sensor b3 of the second sensing unit 11B are respectively disposed on the tire m4, the tire m5 and the tire. m6. Further, in the fourth embodiment, the master sensor c1 , the slave sensor c2 and the slave sensor c3 of the third sensing unit 11C are respectively disposed at the right rear of the vehicle 6 , respectively. The tire m7, the tire m8 and the tire m9 on the side. And, as shown in FIG. 7 , the master sensor c1 is closer to the processing unit 12 than the slave sensor c2 and the slave sensor c3, but is closer to the master sensor of the first sensing unit 11A a1 is further away from the processing unit 12 , in other words, in the fourth embodiment, the distance between the main sensor a1 and the processing unit 12 is smaller than the distance between the main sensor c1 and the processing unit 12 distance.

With further reference to FIG. 8 , the following exemplarily describes how the tire condition sensing system 1 of the fourth embodiment implements the tire condition transmission part of the tire condition sensing method.

First, in step S31, the processing unit 12 outputs the sensing instruction by wireless transmission. Different from the first embodiment, in the fourth embodiment, the sensing instruction output by the processing unit 12 not only indicates the main sensor a1 and the main sensor b1, but also further indicates out the main sensor c1. Next, the flow proceeds to step S32, step S33 and step S34. It should be added that, in the fourth embodiment, step S32, step S33 and step S34 may be performed simultaneously, for example, but in other implementations, there is not necessarily a fixed relationship between step S32, step S33 and step S34. sequence relationship.

In step S32 following step S31, after the main sensor a1 receives the sensing command output by the processing unit 12 in a wireless transmission manner, the first sensing unit 11A executes the first sensing command The sensing procedure, and the manner in which the first sensing unit 11A executes the first sensing procedure is, for example, the same as that of the first embodiment, so it will not be repeated here.

In step S33 subsequent to step S31, after the main sensor b1 receives the sensing command by wireless transmission, the second sensing unit 11B executes the second sensing procedure, and the second sensing unit 11B executes the second sensing procedure. The manner in which the sensing unit 11B executes the second sensing procedure is, for example, the same as that of the first embodiment, so it will not be repeated here.

In step S34 following step S31, after the main sensor a1 receives the sensing command output by the processing unit 12 in a wireless transmission manner, the main sensor a1 sends the sensing command The output is wirelessly transmitted for reception by the main sensor c1 of the third sensing unit 11C. In particular, since the main sensor c1 in the fourth embodiment is far away from the processing unit 12, and the main sensor a1 is closer to the processing unit 12 than the main sensor c1, therefore , by the main sensor a1 outputting the sensing command by wireless transmission, it can prevent the main sensor c1 from being too far away from the processing unit 12 to receive the sensing generated by the processing unit 12 test command.

In step S35 subsequent to step S34, after the main sensor c1 receives the sensing command by wireless transmission (for example, the sensing command output by the main sensor a1), the The third sensing unit 11C performs a sensing procedure. Moreover, for the convenience of description, the sensing procedure performed by the third sensing unit 11C is herein referred to as a third sensing procedure in the fourth embodiment.

Specifically, when the third sensing unit 11C executes the third sensing procedure, the main sensor c1 will sense the tire m7 corresponding to itself according to the sensing instruction to generate a Corresponds to the tire condition information of the tire m7. In addition, the master sensor c1 will also output an indication of the slave sensor c2 and the slave sensor c3 by wireless transmission according to the sensing command for the slave sensor c2 and the slave sensor c2. The third control command received by the sensor c3 in the form of wireless transmission.

Next, after the slave sensor c2 receives the third control command by wireless transmission, the slave sensor c2 senses the tire m8 corresponding to itself according to the third control command to generate a The tire condition data corresponding to the tire m8 is outputted by wireless transmission for the main sensor c1 to receive.

On the other hand, after the slave sensor c3 receives the third control command through wireless transmission, the slave sensor c3 senses the tire m9 corresponding to itself according to the third control command A pair of tire condition data corresponding to the tire m9 is generated, and the tire condition data corresponding to the tire m9 is output by wireless transmission for the main sensor c1 to receive.

In addition, the tire condition data corresponding to the tire m7 is generated at the master sensor c1, and the data generated by the slave sensor c2 and the slave sensor c3 and corresponding to the tire are also received by wireless transmission. After the two tire condition data of the tire m8 and the tire m9 are obtained, the main sensor c1 will output the three tire condition data corresponding to the tire m7, the tire m8 and the tire m9 by wireless transmission, to It is received by the main sensor a1 of the first sensing unit 11A. Moreover, in this embodiment, the main sensor c1 may, for example, first generate an integrated data, and the integrated data includes the three tire condition data corresponding to the tire m7, the tire m8, and the tire m9, respectively, Then, the main sensor c1 outputs the integrated data by wireless transmission for the main sensor a1 to receive. However, in other embodiments, the main sensor c1 can also sequentially output the three pieces of tire condition data corresponding to the tire m7, the tire m8 and the tire m9 in sequence one by one for the main sensor The detector a1 receives, and is not limited to this embodiment. It should be added that the content of each tire condition data in the fourth embodiment is the same as that in the first embodiment, so it will not be described in detail here.

In step S36 subsequent to step S35, the main sensor a1 of the first sensing unit 11A receives wireless transmissions generated by the third sensing unit 11C and corresponding to the tire m7, After the three pieces of tire condition data of the tire m8 and the tire m9, the main sensor a1 will output the three pieces of tire condition data corresponding to the tire m7, the tire m8 and the tire m9 through wireless transmission. , for the processing unit 12 to receive. That is to say, in the fourth embodiment, the master sensor c1 uses the tire condition data generated by itself (that is, the tire condition data corresponding to the tire m7) and the tire condition data generated by the slave sensor c2. The tire condition data (that is, the tire condition data corresponding to the tire m8) and the tire condition data generated from the sensor c3 (that is, the tire condition data corresponding to the tire m9) through the first sense The main sensor a1 of the detection unit 11A is provided to the processing unit 12 by means of wireless transmission. In other words, in the fourth embodiment, the main sensor a1 is equivalent to assisting the main sensor c1 to output the three pieces of tire condition data corresponding to the tire m7, the tire m8 and the tire m9 respectively For the processing unit 12 to receive, to prevent the processing unit 12 from being too far from the main sensor c1 to receive the three tire condition data generated by the third sensing unit 11C.

In step S37 following step S32, step S33 and step S36, when the processing unit 12 receives the three data generated by the first sensing unit 11A and corresponding to the tire m1, the tire m2 and the tire m3 respectively One tire condition data, the three tire condition data generated by the second sensing unit 11B and corresponding to the tire m4, the tire m5 and the tire m6 respectively, and the third sensing unit 11C generated and corresponding to the tire After the three pieces of tire condition data of the tire m7, the tire m8, and the tire m9, the processing unit 12, for example, provides the tire pressure values corresponding to the nine pieces of tire condition data of the tire m1 to the tire m9 to the vehicle computer. The system 62 is used so that the on-board computer system 62 can add the nine tire pressure values to a tire pressure sensing record, or display the nine tire pressure values to the user for reference.

It should be added that, in a similar implementation aspect of the fourth embodiment, step S34 may be omitted. More specifically, since the processing unit 12 can be set to perform wireless transmission with higher power and have a longer transmission distance, in a similar implementation aspect of the fourth embodiment, if the main sensor c1 can directly receive the sensing instruction output by the processing unit 12, then the main sensor a1 does not need to wirelessly transmit the sensing instruction after receiving the sensing instruction for the main sensor Detector c1 receives.

The above is the exemplary description of the fourth embodiment of the present invention. It should be added that the technical means described in the foregoing first to fourth embodiments can be implemented in combination with each other.

To sum up, for each sensing unit 11 of the tire condition sensing system 1 , the master sensor 111 of the sensing unit 11 can receive the respective output from the slave sensors 112 through wireless transmission. Wait for the tire condition data, and then output the tire condition data generated from the sensor 112 by wireless transmission for the processing unit 12 to receive, that is, the main sensor 111 will output other In addition to the tire condition data generated by itself, the tire condition data generated by the slave sensors 112 can also be output instead of the slave sensors 112 for the processing unit 12 to receive. The unit 12 is far apart from the slave sensors 112 and cannot directly communicate wirelessly with the slave sensors 112 , and the processing unit 12 can still receive the data from the slave sensors through the master sensor 111 . The tire condition data generated by the detector 112 is used. In addition, in some embodiments, the main sensor 111 can even receive tire condition data generated by other sensing units 11 from other main sensors 111 , and use the tire condition data generated by other sensing units 11 The output is wirelessly transmitted for the processing unit 12 to receive, thereby preventing the processing unit 12 from being too far apart from other main sensors 111 to receive tire condition data. Therefore, by implementing the tire condition sensing method, the tire condition sensing system 1 can improve the situation that the tire pressure of one end of a large vehicle is difficult to be transmitted to the other end, so the object of the present invention can indeed be achieved.

However, the above are only examples of the present invention, and should not limit the scope of the present invention. Any simple equivalent changes and modifications made according to the scope of the application for patent of the present invention and the content of the patent specification are still within the scope of the present invention. within the scope of the invention patent.
