Description

Tire condition sensing method and system

[ field of technology ]

The present invention relates to a tire condition sensing method, and more particularly to a tire condition sensing method for sensing tire pressure of a vehicle. The invention also relates to a tyre condition sensing system capable of implementing the tyre condition sensing method.

[ background Art ]

The tire pressure of the tire is critical to driving safety, so it is really necessary to monitor whether the tire pressure is normal or not in real time by using the tire pressure sensing system, and the tire pressure sensor transmitting the tire pressure data in a wireless manner is also beginning to be popularized gradually based on the convenience of installation and maintenance.

However, in the case of large vehicles with a long wheelbase (such as buses, vans, and coupling vehicles), since the tires are distributed at a long distance, if a host machine receiving tire pressure data is provided at the head, a tire pressure sensor of the tire disposed near the tail is far from the host machine. On the other hand, the tire pressure sensor is usually operated continuously by the power of the internal battery, so that in order to prolong the endurance time of the battery as long as possible under the condition that the tire pressure sensor is operated for a long time, the tire pressure sensor can only perform wireless transmission with lower power so as to avoid over-fast power consumption. In this way, the wireless signal output by the tire pressure sensor closer to the tail is more likely to be received by the host computer as the transmission distance is reduced. Thus, there remains a need in the art for improvement.

[ detailed description ] of the invention

Before the present invention is described in detail, it should be noted that in the following description, like components are denoted by the same reference numerals. In addition, unless otherwise specified, "electrically connected" in the present specification refers broadly to a wired electrical connection between a plurality of electronic devices/apparatuses/components connected by conductive materials, and a radio connection for transmitting wireless signals by wireless communication technology. In another aspect, the term "electrical connection" as used herein refers to a "direct electrical connection" formed by directly connecting two electronic devices/apparatuses/components, and a "indirect electrical connection" formed by connecting two electronic devices/apparatuses/components via other electronic devices/apparatuses/components.

Referring to fig. 1 and 2 together, a first embodiment of the tire condition sensing system 1 of the present invention is adapted to be disposed in a vehicle 5 as shown in fig. 2, for example.

As shown in fig. 1, in the present embodiment, the tire condition sensing system 1 includes, for example, two sensing units 11 and a processing unit 12. Furthermore, in the present embodiment, each sensing unit 11 includes, for example, three sensors, where each sensor has, for example, a tire pressure sensing component and is adapted to measure the tire pressure of the tire.

In the present embodiment, for the three sensors of each sensing unit 11, one of the three sensors is used as a master sensor 111 included in the sensing unit 11, for example, and the other two of the three sensors are used as two slave sensors 112 included in the sensing unit 11, respectively, for example. The master sensor 111 of each sensing unit 11 can be electrically connected to each slave sensor 112 of the sensing unit 11 and the processing unit 12 in a bi-directional wireless transmission manner for wireless communication, and the wireless transmission in the present embodiment can be implemented by any wireless communication technology, such as one or a combination of more of bluetooth, radio frequency identification (i.e. RFID), wi-Fi, etc., but not limited thereto.

For the sake of more specific description of the present embodiment, as shown in fig. 1, the two sensing units 11 are referred to herein as a first sensing unit 11A and a second sensing unit 11B, respectively. The master sensor 111 of the first sensing unit 11A is referred to as a master sensor a1 of the present embodiment, and the two slave sensors 112 of the first sensing unit 11A are referred to as a slave sensor a2 and a slave sensor a3 of the present embodiment, respectively. On the other hand, the master sensor 111 of the second sensing unit 11B is referred to as a master sensor B1 of the present embodiment, and the two slave sensors 112 of the second sensing unit 11B are referred to as a slave sensor B2 and a slave sensor B3 of the present embodiment, respectively.

In the present embodiment, the processing unit 12 may be implemented as a tire condition sensing host, for example, and the processing unit 12 is adapted to be electrically connected to a vehicle-mounted computer system 52 included in the vehicle 5, for example. However, in other embodiments, the processing unit 12 may be implemented as the on-board computer system 52 itself, for example, or may be included within the on-board computer system 52 as part of the on-board computer system 52, for example. More specifically, the processing unit 12 may be installed on the vehicle 5, for example, before the vehicle 5 is shipped, or may be installed on the vehicle 5, for example, after the vehicle 5 is shipped, so the actual implementation of the processing unit 12 is not limited to this embodiment.

As shown in fig. 2, the vehicle 5 in which the tire condition sensing system 1 of the present embodiment is disposed includes, for example, a vehicle body 51, the on-board computer system 52, and six tires 53 disposed under the vehicle body 51. The in-vehicle computer system 52 is, for example, a head portion 511 provided to the vehicle body 51. In the present embodiment, the processing unit 12 is also disposed at the head portion 511 of the vehicle body 51, and is electrically connected to the vehicle-mounted computer system 52 by wire, but not limited thereto.

For convenience of explanation of the tire condition sensing system 1 of the present embodiment, the six tires 53 of the vehicle 5 are referred to as a tire m1, a tire m2, a tire m3, a tire m4, a tire m5 and a tire m6 shown in fig. 2.

In the present embodiment, as shown in fig. 2, the master sensor a1, the slave sensor a2, and the slave sensor a3 of the first sensor unit 11A are, for example, the tire m1, the tire m2, and the tire m3 respectively provided near the right side of the vehicle 5, and the master sensor B1, the slave sensor B2, and the slave sensor B3 of the second sensor unit 11B are, for example, the tire m4, the tire m5, and the tire m6 respectively provided near the left side of the vehicle 5.

Thus, as shown in fig. 2, the distance between the master sensor a1 and the processing unit 12 is smaller than the distance between the slave sensor a2 and the processing unit 12 and smaller than the distance between the slave sensor a3 and the processing unit 12. On the other hand, the distance between the master sensor b1 and the processing unit 12 is smaller than the distance between the slave sensor b2 and the processing unit 12 and smaller than the distance between the slave sensor b3 and the processing unit 12. In other words, the master sensor a1 is closer to the processing unit 12 than the slave sensors a2 and a3, and the master sensor b1 is closer to the processing unit 12 than the slave sensors b2 and b 3.

It should be understood that the tire condition sensing system 1 of the present invention can be applied to vehicles of various tire numbers, and thus the vehicle 5 shown in fig. 2 is only for exemplary purposes of illustrating the operation of the present embodiment, and is not intended to limit the scope of the present invention. In other embodiments, the number of the sensing units 11 and the number of the slave sensors 112 of each sensing unit 11 may be freely adjusted according to the number of the tires of the vehicle in which the tire condition sensing system 1 is disposed, so in other embodiments, the tire condition sensing system 1 may also include one, three or more sensing units 11, and each sensing unit 11 may also include one, three or more slave sensors 112, but is not limited to this embodiment.

Further, it should be understood that the manner in which the master sensors 111 (i.e., the master sensor a1 and the master sensor b 1) and the slave sensors 112 (i.e., the slave sensor a2, the slave sensor a3, the slave sensor b2 and the slave sensor b 3) are disposed on the vehicle 5 in fig. 2 is merely for illustration. Specifically, for the main sensor 111 of each sensing unit 11, it is only necessary that the main sensor 111 is close enough to the processing unit 12 so that the main sensor 111 and the processing unit 12 can smoothly communicate with each other wirelessly. On the other hand, for each slave sensor 112 of each sensing unit 11, it is only necessary to ensure that the slave sensor 112 is sufficiently close to the master sensor 111 of the same sensing unit 11 so that the slave sensor 112 can smoothly communicate wirelessly with the master sensor 111 of the same sensing unit 11 with each other. Therefore, the configuration of the master sensors 111 and the slave sensors 112 is not limited to the embodiment.

How the tire condition sensing system 1 of the present embodiment implements a tire condition sensing method is exemplarily described in detail below.

In this embodiment, the tire condition sensing method includes, for example, a tire condition transmitting section and an abnormality detecting section. Referring to fig. 1 to 3, the following describes how the tire condition sensing system 1 performs the tire condition transmission part of the tire condition sensing method.

First, in step S11, the processing unit 12 outputs a sensing command in a wireless transmission manner. In this embodiment, the sensing instruction indicates, for example, the main sensor a1 and the main sensor b1, and is used for receiving the main sensor a1 and the main sensor b1 in a wireless transmission manner. 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 in a wireless transmission manner, the first sensing unit 11A executes a sensing procedure. Also, for convenience of the following description, the sensing procedure performed by the first sensing unit 11A is referred to herein as a first sensing procedure of the present embodiment.

Specifically, during the first sensing process performed by the first sensing unit 11A, the main sensor a1 senses the corresponding tire m1 according to the sensing command to generate tire condition data corresponding to the tire m 1. The master sensor a1 also outputs a first control command indicating the slave sensor a2 and the slave sensor a3 in a wireless transmission manner according to the sensing command, wherein the first control command is used for the slave sensor a2 and the slave sensor a3 to receive in a wireless transmission manner.

Then, after the slave sensor a2 receives the first control command in a wireless transmission manner, the slave sensor a2 senses the corresponding tire m2 according to the first control command to generate tire condition data corresponding to the tire m2, and outputs the tire condition data corresponding to the tire m2 in a wireless transmission manner for receiving by the master sensor a 1.

On the other hand, after the slave sensor a3 receives the first control command in a wireless transmission manner, the slave sensor a3 senses the corresponding tire m3 according to the first control command to generate tire condition data corresponding to the tire m3, and outputs the tire condition data corresponding to the tire m3 in a wireless transmission manner for the master sensor a1 to receive.

After the master sensor a1 generates the tire condition data corresponding to the tire m1 and also receives the two tire condition data respectively generated by the slave sensor a2 and the slave sensor a3 and respectively corresponding to the tire m2 and the tire m3 in a wireless transmission manner, the master sensor a1 outputs the three tire condition data respectively corresponding to the tire m1, the tire m2 and the tire m3 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 m 3. In this embodiment, the main sensor a1 may generate an integrated data, and the integrated data includes three tire condition data corresponding to the tire m1, the tire m2 and the tire m3, respectively, and then 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 m 3. However, in other embodiments, the main sensor a1 may, for example, sequentially output the three tire condition data corresponding to the tire m1, the tire m2 and the tire m3 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 away from the processing unit 12, by the first sensing procedure, the master sensor a1 can output the two tire condition data for the processing unit 12 to receive in a wireless transmission manner after receiving the two tire condition data generated and output by the slave sensor a2 and the slave sensor a 3. In other words, the master sensor a1 can output the two sets of tire condition data corresponding to the tire m2 and the tire m3 for the processing unit 12 to receive, in place of the slave sensor a2 and the slave sensor a3, in addition to outputting the tire condition data (i.e., the tire condition data corresponding to the tire m 1) generated by itself for the processing unit 12 to receive. Therefore, even if the processing unit 12 is far from the slave sensor a2 and the slave sensor a3 and cannot directly perform wireless communication with the slave sensor a2 and the slave sensor a3, the processing unit 12 can still receive the two sets of tire condition data corresponding to the tire m2 and the tire m3 through the master sensor a 1.

In step S13, after the main sensor B1 receives the sensing instruction in a wireless transmission manner, the second sensing unit 11B performs another sensing procedure. Also, for convenience of the following description, the sensing procedure performed by the second sensing unit 11B is referred to herein as a second sensing procedure of the present embodiment.

Specifically, during the second sensing process performed by the second sensing unit 11B, the main sensor B1 senses the corresponding tire m4 according to the sensing command to generate tire condition data corresponding to the tire m 4. The master sensor b1 also outputs a second control command indicating the slave sensor b2 and the slave sensor b3 in a wireless transmission manner according to the sensing command, wherein the second control command is used for the slave sensor b2 and the slave sensor b3 to receive in a wireless transmission manner.

Then, after the secondary sensor b2 receives the second control command in a wireless transmission manner, the secondary sensor b2 senses the corresponding tire m5 according to the second control command to generate tire condition data corresponding to the tire m5, and outputs the tire condition data corresponding to the tire m5 in a wireless transmission manner for receiving by the primary sensor b 1.

On the other hand, after the secondary sensor b3 receives the second control command in a wireless transmission manner, the secondary sensor b3 senses the corresponding tire m6 according to the second control command to generate tire condition data corresponding to the tire m6, and outputs the tire condition data corresponding to the tire m6 in a wireless transmission manner for the primary sensor b1 to receive.

After the master sensor b1 generates the tire condition data corresponding to the tire m4, and also receives the two tire condition data respectively generated by the slave sensor b2 and the slave sensor b3 and respectively corresponding to the tire m5 and the tire m6 in a wireless transmission manner, the master sensor b1 outputs the three tire condition data respectively corresponding to the tire m4, the tire m5 and the tire m6 in a wireless transmission manner for the processing unit 12 to receive. In this embodiment, the main sensor b1 may generate another integrated data, and the other integrated data includes the three tire condition data corresponding to the tire m4, the tire m5 and the tire m6, respectively, and then the main sensor b1 outputs the other 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 m4, the tire m5 and the tire m 6. However, in other embodiments, the main sensor b1 may, for example, sequentially output the three tire condition data corresponding to the tire m4, the tire m5 and the tire m6 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, the slave sensor b2 and the slave sensor b3 are separated from the processing unit 12 by a relatively long distance, but by means of the second sensing procedure, the master sensor b1 is capable of outputting the two tire condition data for the processing unit 12 in a wireless transmission manner after receiving the two tire condition data generated and outputted by the slave sensor b2 and the slave sensor b 3. In other words, the master sensor b1 can output the two sets of tire condition data corresponding to the tire m5 and the tire m6 for the processing unit 12 to receive, in place of the slave sensor b2 and the slave sensor b3, in addition to outputting the tire condition data generated by itself (i.e., the tire condition data corresponding to the tire m 4) for the processing unit 12 to receive. Therefore, even if the processing unit 12 is far from the slave sensor b2 and the slave sensor b3 and cannot directly perform wireless communication with the slave sensor b2 and the slave sensor b3, the processing unit 12 can still receive the two sets of tire condition data corresponding to the tire m5 and the tire m6 through the master sensor b 1.

In addition, in the present 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 identifier. Wherein the tire pressure value indicates the tire pressure of the tire 53 corresponding to the tire condition data, and the identifier indicates, for example, the sensor generating the tire condition data, and is used by the processing unit 12 to identify which sensor the tire condition data is generated by, in other words, the identifier is equivalent to the processing unit 12 identifying which tire 53 of the vehicle 5 the tire condition data corresponds to. It should be noted that, in other embodiments, each sensor has a temperature sensing component, and each tire condition data may further include a temperature value of the corresponding tire 53, but not limited thereto.

In step S14, when the processing unit 12 receives the three tire condition data outputted by the main sensor a1 in a wireless transmission manner and corresponding to the tire m1, the tire m2 and the tire m3 respectively, and also receives the three tire condition data outputted by the main sensor b1 in a wireless transmission manner and corresponding to the tire m4, the tire m5 and the tire m6 respectively, the processing unit 12 provides at least tire pressure values corresponding to the six tire condition data of the six tires 53 to the on-board computer system 52, for example, so that the on-board computer system 52 can add the six tire pressure values to a tire pressure sensing record, or display the six tire pressure values to a user reference, but not limited thereto.

It should be noted that, in the present 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, so that, in order to avoid the first sensing unit 11A and the second sensing unit 11B interfering with each other during the execution of the first sensing procedure and the second sensing procedure, the first sensing unit 11A and the second sensing unit 11B output the tire condition data by using different frequencies, for example, but not limited thereto, using a frequency division multiple access technology (Frequency Division Multiple Access, abbreviated as FDMA).

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

In the process of executing the first sensing procedure by the first sensing unit 11A, the master sensor a1 of the first sensing unit 11A outputs the first control command for the slave sensor a2 and the slave sensor a3, for example, through a second channel corresponding to a second frequency range, and the master sensor a1 receives the two-tire condition data generated and output by the slave sensor a2 and the slave sensor a3, for example, through the second channel, and outputs the master sensor a1 itself, the slave sensor a2 and the three-tire condition data generated by the slave sensor a3, respectively, for the processing unit 12, through the second channel.

On the other hand, during the second sensing process performed by the second sensing unit 11B, the master sensor B1 of the second sensing unit 11B outputs the second control command for the slave sensor B2 and the slave sensor B3 to receive the second control command through a third channel corresponding to a third frequency range, and the master sensor B1 receives the two tire condition data generated and output by the slave sensor B2 and the slave sensor B3 through the third channel, and outputs the three tire condition data generated by the master sensor B1 itself, the slave sensor B2 and the slave sensor B3 respectively for the processing unit 12 to receive the third channel.

More specifically, for example, the first frequency range, the second frequency range, and the third frequency range may be implemented as 61kHz to 64kHz, 65kHz to 68kHz, and 69kHz to 72kHz, respectively, for example, in the present embodiment, that is, the first frequency range to the third frequency range may be completely non-overlapping with each other, for example. However, in other embodiments, the first to third frequency ranges may be implemented in a form of not completely overlapping each other, for example, 60kHz to 65kHz, 64kHz to 69kHz, and 68kHz to 73kHz, respectively. In general, the first to third frequency ranges are in the form of not overlapping each other completely or not overlapping each other completely.

It is noted that, in the present embodiment, the sensing instruction output by the processing unit 12 in step S11 includes, for example, a first instruction portion corresponding to the main sensor a1 and a second instruction portion corresponding to the main sensor B1, wherein the first sensing unit 11A executes the first sensing program according to, for example, the first instruction portion of the sensing instruction in step S12, and the second sensing unit 11B executes the second sensing program according to, for example, the second instruction portion of the sensing instruction in step S13. More specifically, for the first sensing unit 11A, the first instruction portion of the sensing instruction indicates, for example, the complete operation step of the first sensing program in the present embodiment, however, in other embodiments, the complete operation step of the first sensing program may be stored in the master sensor a1, the slave sensor a2 and the slave sensor a3 in advance, and the first instruction portion of the sensing instruction is only used as a trigger signal for triggering the first sensing unit 11A to start executing the first sensing program, which is not limited to the present embodiment. On the other hand, the second instruction portion of the sensing instruction indicates the complete operation step of the second sensing procedure in the present embodiment, but is similar to the first instruction portion of the sensing instruction, so will not be repeated here, however, in other embodiments, the second instruction portion of the sensing instruction may be just a trigger signal for triggering the second sensing unit 11B to start executing the second sensing procedure, and is not limited to the present embodiment.

The above is an exemplary description of the tire condition transmission portion of the tire condition sensing method. It is added that the tire condition sensing system 1 may automatically execute the tire condition transmission part once, for example, when the vehicle 5 is started, so that the on-board computer system 52 performs the initialization detection procedure of the vehicle 5 according to the tire condition data. Alternatively, the tire condition sensing system 1 may periodically execute the tire condition transmission part a plurality of times, for example, in the case where the vehicle 5 is started, so that the on-board computer system 52 may perform the tire condition monitoring process of the vehicle 5 according to the tire condition data.

Next, referring to fig. 1, 2 and 4 together, the following describes how the tire condition sensing system 1 performs the abnormality detection portion 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 sensors"), the sensor senses the tire 53 corresponding to itself 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 sensor determines that the tire pressure value is within a normal tire pressure range, the flow of the abnormality detection portion is ended, and if the sensor determines that the tire pressure value is within a normal tire pressure range, the flow proceeds to step S23.

In step S23 subsequent to step S22, once the sensor determines that the tire pressure value is not within the normal tire pressure range, the sensor determines that a tire condition abnormality condition is met, and outputs an abnormality notification corresponding to the tire condition abnormality condition through a fourth channel corresponding to a fourth frequency range in a wireless transmission manner, wherein the fourth frequency range is, for example, not completely overlapped with each of the first to third frequency ranges or not completely overlapped with each other.

Specifically, in the present embodiment, the tire condition transmitting portion and the abnormality detecting portion of the tire condition sensing method are executed simultaneously by the tire condition sensing system 1, for example, so that the occurrence of interference of the abnormality notification on the first to third channels can be avoided by outputting the abnormality notification through the fourth channel by the sensor.

If the sensor is one of the main sensor a1 and the main sensor b1, the abnormality notification indicates the processing unit 12, for example, and is used for the processing unit 12 to directly receive in a wireless transmission manner. On the other hand, if the sensor is one of the slave sensor a2 and the slave sensor a3, the abnormality notification indicates, for example, the master sensor a1 for the master sensor a1 to receive, and in this case, the master sensor a1 outputs the abnormality notification in a wireless transmission manner through the fourth channel for the processing unit 12 to receive when receiving the abnormality notification. In yet another aspect, if the sensor is one of the slave sensor b2 and the slave sensor b3, the anomaly notification is, for example, indicative of the master sensor b1 for receipt by the master sensor b1, and in this case, the master sensor b1 will output the anomaly notification in a wireless transmission manner for receipt by the processing unit 12 via the fourth channel upon receipt of the anomaly notification.

Next, the flow proceeds to step S24.

In step S24, when the processing unit 12 receives the abnormality notification, the processing unit 12 generates and outputs an alarm notification for prompting the user according to the abnormality notification, and the alarm notification indicates, for example, the sensor generating the abnormality notification. Thereby, the warning notification can prompt the user that the tire 53 corresponding to the sensor is abnormal in tire pressure. More specifically, in the present embodiment, the processing unit 12 may output the warning notification, for example, through the in-vehicle computer system 52, and the warning notification may be implemented, for example, as a warning light signal of the tire 53 indicating the abnormal tire pressure. However, in other embodiments, the processing unit 12 may also output the alert notification to the mobile phone of the user in a push manner, for example, but not limited to this embodiment.

The above is an exemplary description of the abnormality detection portion of the tire condition sensing method. It should be noted that, in the preferred embodiment, the tire condition sensing system 1 can execute the abnormality detecting portion of the tire condition sensing method, for example, when the electric door of the vehicle 5 is opened but not started.

It is added that, in the present embodiment, the tire condition transmission part of the tire condition sensing method is, for example, a resident mechanism that is used as the tire condition sensing. However, in other embodiments, the tire condition transmission portion of the tire condition sensing method may also be, for example, a spare mechanism that is used 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 receiving the tire condition data output by the master sensors 111 and the slave sensors 112 in a wireless transmission manner under the normal operation condition, and then outputting the tire condition data output by the master sensors 111 and the slave sensors 112 in a wireless transmission manner for the processing unit 12 to receive, however, when the processing unit 12 determines that the repeater is not operating normally, the tire condition sensing system 1 performs the tire condition transmission portion of the tire condition sensing method, so that the master sensors 111 can replace the function of the repeater.

The invention also provides a second embodiment of the tire condition sensing system 1, and the difference between the second embodiment and the first embodiment is the execution mode 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 flow proceeds to step S12 and step S13 simultaneously as shown in fig. 3, that is, in the first embodiment, the period in which the first sensing unit 11A executes the first sensing program and the period in which the second sensing unit 11B executes the second sensing program overlap each other.

However, in the second embodiment, after the processing unit 12 outputs the sensing instruction in step S11, the flow proceeds to step S12, for example, as shown in fig. 5, and after step S12 ends, the flow proceeds to step S13. That is, in the second embodiment, the second sensing unit 11B may perform the second sensing process after the first sensing unit 11A performs the first sensing process. In other words, in the second embodiment, the period during which the first sensing unit 11A performs the first sensing procedure and the period during which the second sensing unit 11B performs the second sensing procedure do not overlap each other at all.

If, for example, in fig. 2, in the second embodiment, the period during which the main sensor a1 outputs the three sets of tire condition data corresponding to the tire m1, the tire m2 and the tire m3 respectively in a wireless transmission manner is not overlapped with the period during which the main sensor b1 outputs the three sets 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 sensor b1 output the tire condition data by using, for example, a time division multiplexing technique (Time Division Multiple Access, abbreviated TDMA). More specifically, in the second embodiment, the sensing instruction output by the processing unit 12 includes, for example, the first instruction portion corresponding to the main sensor a1 and the second instruction portion corresponding to the main sensor b1, where the first instruction portion includes, for example, a first return time (e.g., "8 hours 0 minutes 0 seconds") corresponding to the main sensor a1 and later than the current time, and the second instruction portion includes, for example, a second return time (e.g., "8 hours 0 minutes 15 seconds") corresponding to the main sensor b1 and later than the first return time. In the second embodiment, the main sensor a1 continuously outputs the three tire condition data corresponding to the tire m1, the tire m2 and the tire m3 respectively in a wireless transmission manner for a period of time (for example, 10 seconds) for the processing unit 12 to receive, for example, when the first return time is partially reached according to the first command. On the other hand, the main sensor b1 continuously outputs the three tire condition data corresponding to the tire m4, the tire m5 and the tire m6 respectively in a wireless transmission manner for a period of time (for example, 10 seconds) for the processing unit 12 to receive, for example, when the second command is partially reached at the second return time.

In this way, even if the tire condition sensing system 1 of the second embodiment does not utilize the frequency division multiple access technology, it can be ensured that the first sensing unit 11A and the second sensing unit 11B do not interfere with each other when outputting the tire condition data, however, alternatively, 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, which is similar to the second embodiment, and the difference between the third embodiment and the second embodiment is the execution mode of the tire condition transmission part of the tire condition sensing method.

With reference to fig. 6 in conjunction with fig. 1 and 2, the following exemplarily illustrates how the tire condition sensing system 1 of the third embodiment implements a tire condition transmission part of the tire condition sensing method.

First, in step S101, the processing unit 12 outputs a tire pressure report command in a wireless transmission manner. In the third embodiment, the tire pressure report command indicates all the master sensors 111 and the slave sensors 112, that is, the tire pressure report command is received by each of the master sensors 111 and the slave sensors 112 in a wireless transmission manner in the third embodiment. It is noted that the processing unit 12 may be operated by electric energy of the battery of the vehicle 6, for example, without considering the problem of electric power endurance, so that the processing unit 12 may be configured to perform wireless transmission with higher power than the master sensor 111 and the slave sensor 112, and may have a longer transmission distance, and it is assumed that each of the master sensor 111 and the slave sensor 112 may directly receive the tire pressure report command outputted by the processing unit 12 in a wireless transmission manner.

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

In step S102, for each of the master sensor 111 and the slave sensor 112 (hereinafter referred to as "the sensor"), when the sensor receives the tire pressure report command in a wireless transmission manner, the sensor senses the tire 53 corresponding to the sensor itself to obtain a tire pressure value corresponding to the tire 53, and generates a tire condition data, wherein the tire condition data includes, for example, the tire pressure value and an identifier which corresponds to the sensor itself and has a unique property. 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 in a wireless transmission manner for the processing unit 12 to receive. Preferably, the master sensors 111 and the slave sensors 112 may output the tire condition data respectively, for example, by using at least one of a frequency division multiple access technology and a time division multiple access technology. For example, in the case of using the time division multiplexing technology, the master sensors 111 and the slave sensors 112 may output the tire condition data generated by themselves in a wireless transmission manner for a period of time (for example, 5 seconds), and the time point and the duration of the output of the tire condition data by each of the master sensors 111 and the slave sensors 112 may be indicated by the tire pressure report command output by the processing unit 12, for example, but not limited thereto. 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 away from the processing unit 12, it is assumed here that the four pieces of tire condition data generated and outputted by the four slave sensors 112 cannot be directly received by the processing unit 12 for convenience of explanation, that is, the processing unit 12 receives only the two pieces of tire condition data generated by the master sensor a1 and the master sensor b1 in step S103, but cannot receive the four pieces of tire condition data generated by the slave sensor a2, the slave sensor a3, the slave sensor b2 and the slave sensor b 3.

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 is over, the processing unit 12 determines whether the tire condition data generated by each of the master sensor 111 and the slave sensors 112 is received. The tire pressure reporting period is, for example, a period of time (e.g., 30 seconds) from when the processing unit 12 outputs the tire pressure reporting command. In step S103, the processing unit 12 only receives the two sets of tire condition data generated by the master sensor a1 and the master sensor b1, and thus, in step S104, the processing unit 12 determines 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, for example. Next, the flow proceeds to step S11.

In step S11, the processing unit 12 outputs the sensing command in a wireless transmission manner, and, similar to the second embodiment, the sensing command includes, for example, the first command portion and the second command portion, wherein the first command portion includes, for example, the first return time (e.g., "8 h 0 min 0S") corresponding to the main sensor a1, and the second command portion includes, for example, the second return time "8 h 0 min 15S" corresponding to the main sensor b 1. 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 is not received, the first instruction portion of the sensing instruction further includes, for example, a tire condition data repair request indicating the slave sensor a2 and the slave sensor a3 and being recognized by the master sensor a 1. 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 is not received, the second instruction portion of the sensing instruction further includes, for example, a tire condition data repair request indicating the slave sensor b2 and the slave sensor b3 and being recognized by the master sensor b 1.

It should be noted that, in the preferred embodiment, if the processing unit 12 receives the tire condition data generated by the slave sensor a2 in step S103, but does not receive the tire condition data generated by the slave sensor a3, the tire condition data repair request of the first command portion indicates only the slave sensor a3, but does not indicate the slave sensor a2, that is, the tire condition data repair requests of the first command portion and the second command portion indicate only the sensor corresponding to each tire condition data that the processing unit 12 should receive but not receive in step S103, but is not limited thereto.

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 instruction portion of the sensing instruction, so that the master sensor a1 outputs at least the two tire condition data (i.e. the two tire condition data corresponding to the tire m2 and the tire m3 respectively) generated by the slave sensor a2 and the slave sensor a3 for a period of time (e.g. 10 seconds) in a wireless transmission manner when the first return time arrives (e.g. when "8 hours 0 minutes 0 seconds" arrives), 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 instruction portion of the sensing instruction, so that the master sensor B1 outputs the two tire condition data (i.e. the two tire condition data corresponding to the tire m5 and the tire m6 respectively) generated by the slave sensor B2 and the slave sensor B3 for a period of time (e.g. 10 seconds) in a wireless transmission manner when the second return time arrives (e.g. when "8 hours 0 minutes 15 seconds" arrives), for the processing unit 12 to receive. Next, the flow proceeds to step S14.

In step S14, after the processing unit 12 receives at least the two tire condition data outputted by the master sensor a1 and corresponding to the tire m2 and the tire m3, respectively, and the two tire condition data outputted by the master sensor b1 and corresponding to the tire m5 and the tire m6, respectively, the processing unit 12 provides the six tire condition data corresponding to the two master sensors 111 and the four slave sensors 112, respectively, for example, to the on-board computer system 52.

It should be noted 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 output the two tire condition data generated by the slave sensor a2 and the slave sensor a3 in a wireless transmission manner for the processing unit 12 to receive, and does not need to sense the tire m1 again to generate the tire condition data, and does not need to output the tire condition data corresponding to the tire m1 generated by the master sensor a1 itself again. More specifically, the main sensor a1 may output the tire condition data not received by the processing unit 12 in step S103 in the first sensing procedure of the third embodiment. Similarly, in step S13, the master sensor b1 may output the two tire condition data generated by the slave sensors b2 and b3 by wireless transmission, without sensing the tire m4 again to generate the tire condition data, or outputting the tire condition data corresponding to the tire m4 generated by the master sensor b1 itself again.

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

Referring to fig. 7 in conjunction with 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 adapted to be disposed in a vehicle 6 shown in fig. 7, for example.

Unlike 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 convenience of explanation, the master sensor 111 of the third sensing unit 11C is used as a master sensor C1 of the fourth embodiment, and the two slave sensors 112 of the third sensing unit 11C are used as a slave sensor C2 and a slave sensor C3 of the present embodiment, respectively.

The vehicle 6 to which the tire condition sensing system 1 of the fourth embodiment is provided includes, for example, a vehicle body 61, a vehicle-mounted computer system 62, and twelve tires 63 provided under the vehicle body 61. The on-board computer system 62 is, for example, disposed at a head portion 611 of the vehicle body 61, and the processing unit 12 of the fourth embodiment is, for example, also disposed at the head portion 611 of the vehicle body 61 in the present embodiment, and is, for example, electrically connected to the on-board computer system 62 by wire, but not limited thereto.

For convenience of explanation, nine tires 63 of the vehicle 6 are referred to herein as a tire m1, a tire m2, a tire m3, a tire m4, a tire m5, a tire m6, a tire m7, a tire m8, and a tire m9, respectively, as shown in fig. 7.

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 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 provided on the tire m7, the tire m8 and the tire m9 located on the right rear side of the vehicle 6. Also, 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 farther from the processing unit 12 than the master sensor a1 of the first sensing unit 11A, in other words, in the fourth embodiment, the distance between the master sensor a1 and the processing unit 12 is smaller than the distance between the master sensor c1 and the processing unit 12.

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

First, in step S31, the processing unit 12 outputs the sensing instruction in a wireless transmission manner. Unlike the first embodiment, in the fourth embodiment, the sensing instruction outputted by the processing unit 12 further indicates the main sensor c1 in addition to the main sensor a1 and the main sensor b1, for example. Next, the flow proceeds to step S32, step S33, and step S34. It is noted that, in the fourth embodiment, the steps S32, S33 and S34 may be performed simultaneously, for example, but in other embodiments, there is not necessarily a fixed sequential relationship between the steps S32, S33 and S34.

In step S32 subsequent to step S31, after the main sensor a1 receives the sensing command outputted by the processing unit 12 in a wireless transmission manner, the first sensing unit 11A executes the first sensing program, and the manner in which the first sensing unit 11A executes the first sensing program is the same as that of the first embodiment, for example, so that the description thereof will not be repeated here.

In step S33 subsequent to step S31, after the main sensor B1 receives the sensing command in a wireless transmission manner, the second sensing unit 11B executes the second sensing program, and the manner in which the second sensing unit 11B executes the second sensing program is the same as that of the first embodiment, for example, so that the description thereof will not be repeated here.

In step S34, which follows step S31, after the main sensor a1 receives the sensing command outputted by the processing unit 12 in a wireless transmission manner, the main sensor a1 outputs the sensing command in a wireless transmission manner for the main sensor C1 of the third sensing unit 11C to receive. Specifically, since the main sensor c1 is far from the processing unit 12 in the fourth embodiment, and the main sensor a1 is closer to the processing unit 12 than the main sensor c1, the main sensor a1 outputs the sensing command in a wireless transmission manner, so that the sensing command generated by the processing unit 12 cannot be received by the main sensor c1 due to being far from the processing unit 12 can be avoided.

In step S35, which follows step S34, after the main sensor C1 receives the sensing command (e.g., the sensing command outputted from the main sensor a 1) in a wireless transmission manner, the third sensing unit 11C executes a sensing procedure. For convenience of description, the sensing procedure performed by the third sensing unit 11C is referred to herein as a third sensing procedure in the fourth embodiment.

Specifically, during the process of executing the third sensing procedure by the third sensing unit 11C, the main sensor C1 senses the corresponding tire m7 according to the sensing command to generate tire condition data corresponding to the tire m 7. The master sensor c1 also outputs a third control command indicating the slave sensor c2 and the slave sensor c3 in a wireless transmission manner according to the sensing command, wherein the third control command is used for the slave sensor c2 and the slave sensor c3 to receive in a wireless transmission manner.

Then, after the slave sensor c2 receives the third control command in a wireless transmission manner, the slave sensor c2 senses the corresponding tire m8 according to the third control command to generate tire condition data corresponding to the tire m8, and outputs the tire condition data corresponding to the tire m8 in a wireless transmission manner for receiving by the master sensor c 1.

On the other hand, after the slave sensor c3 receives the third control command in a wireless transmission manner, the slave sensor c3 senses the corresponding tire m9 according to the third control command to generate tire condition data corresponding to the tire m9, and outputs the tire condition data corresponding to the tire m9 in a wireless transmission manner for the master sensor c1 to receive.

After the master sensor c1 generates the tire condition data corresponding to the tire m7 and also receives the two tire condition data respectively generated by the slave sensor c2 and the slave sensor c3 and respectively corresponding to the tire m8 and the tire m9 in a wireless transmission manner, the master sensor c1 outputs the three tire condition data respectively corresponding to the tire m7, the tire m8 and the tire m9 in a wireless transmission manner for the master sensor a1 of the first sensing unit 11A to receive. In this embodiment, the main sensor c1 may generate an integrated data, and the integrated data includes three tire condition data corresponding to the tire m7, the tire m8 and the tire m9, respectively, and then the main sensor c1 outputs the integrated data for the main sensor a1 to receive. However, in other embodiments, the main sensor c1 may, for example, sequentially output the three sets of tire condition data corresponding to the tire m7, the tire m8 and the tire m9 for the main sensor a1 to receive, but is not limited to this embodiment. It is to be noted that the content of each tire condition data in the fourth embodiment is the same as that in the first embodiment, and thus, the description thereof will not be repeated here.

In step S36 subsequent to step S35, after the main sensor a1 of the first sensing unit 11A receives the three sets of tire condition data generated by the third sensing unit 11C and corresponding to the tire m7, the tire m8 and the tire m9 respectively in a wireless transmission manner, the main sensor a1 outputs the three sets of tire condition data corresponding to the tire m7, the tire m8 and the tire m9 respectively in a wireless transmission manner for the processing unit 12 to receive. That is, in the fourth embodiment, the master sensor c1 provides the tire condition data (i.e., the tire condition data corresponding to the tire m 7) generated by itself, the tire condition data (i.e., the tire condition data corresponding to the tire m 8) generated by the slave sensor c2, and the tire condition data (i.e., the tire condition data corresponding to the tire m 9) generated by the slave sensor c3 to the processing unit 12 in a wireless transmission manner through the master sensor a1 of the first sensing unit 11A. In other words, in the fourth embodiment, the main sensor a1 is equivalent to assist the main sensor C1 to output the three sets of tire condition data corresponding to the tire m7, the tire m8 and the tire m9 respectively for the processing unit 12 to receive, so as to avoid that the processing unit 12 cannot receive the three sets of tire condition data generated by the third sensing unit 11C due to being far from the main sensor C1.

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

It is to be noted that, in a similar implementation 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 of the fourth embodiment, if the main sensor c1 can directly receive the sensing command outputted by the processing unit 12, the main sensor a1 does not need to output the sensing command in a wireless transmission manner for the main sensor c1 to receive after receiving the sensing command.

The above is an illustration of the fourth embodiment of the present invention. It is to be noted that the technical means described in the foregoing first to fourth embodiments can be implemented in combination with each other.

In summary, for each sensing unit 11 of the tire condition sensing system 1, the master sensor 111 of the sensing unit 11 is capable of receiving the tire condition data respectively output by the slave sensors 112 in a wireless transmission manner, and then outputting the tire condition data generated by the slave sensors 112 in a wireless transmission manner for the processing unit 12 to receive, that is, the master sensor 111 can output the tire condition data generated by the slave sensors 112 instead of the slave sensors 112 for the processing unit 12 to receive, so that even if the processing unit 12 is far away from the slave sensors 112 and cannot directly wirelessly communicate with the slave sensors 112, the processing unit 12 can still receive the tire condition data generated by the slave sensors 112 through the master sensor 111. In addition, in some embodiments, the main sensor 111 may even receive the tire condition data generated by the other sensing units 11 from the other main sensor 111, and output the tire condition data generated by the other sensing units 11 for the processing unit 12 to receive in a wireless transmission manner, so as to avoid the situation that the processing unit 12 is far away from the other main sensor 111 and cannot receive the 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 that the object of the invention can be truly achieved.

The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
