Description

Tire condition sensing method and system

[ technical field ] A method for producing a semiconductor device

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

[ background of the invention ]

The tire pressure of a tire is important for driving safety, so it is necessary to monitor whether the tire pressure is normal or not in real time by using a tire pressure sensing system, and a tire pressure sensor for transmitting tire pressure data in a wireless manner is also becoming popular in view of convenience in installation and maintenance.

However, for a large vehicle with a long wheelbase (such as a bus, a truck, a coupling car, etc.), because the tires are distributed at a long distance, if the host receiving the tire pressure data is installed at the head of the vehicle, the tire pressure sensor installed at the tire near the tail of the vehicle will be far away from the host. On the other hand, the tire pressure sensor usually operates continuously by the power of its internal battery, so that the tire pressure sensor can only transmit wirelessly at a low power to avoid over-fast power consumption in order to prolong the endurance time of the battery as much as possible when the tire pressure sensor operates for a long time. As such, the tire pressure sensor closer to the vehicle tail outputs a wireless signal that is more likely to be attenuated with the transmission distance and thus not received by the host correctly. Thus, there remains a need in the art for improvements.

[ detailed description ] embodiments

Before the present invention is described in detail, it should be noted that in the following description, similar components are denoted by the same reference numerals. In addition, unless otherwise specified, the term "electrical connection" in this specification refers to a wired electrical connection between a plurality of electronic devices/apparatuses/components through a conductive material, and a wireless electrical connection through a wireless communication technology for wireless signal transmission. On the other hand, the term "electrical connection" as used in this specification also refers to a "direct electrical connection" formed by direct connection between two electronic devices/apparatuses/components, and an "indirect electrical connection" formed by connection between two electronic devices/apparatuses/components through other electronic devices/apparatuses/components.

Referring to fig. 1 and 2 together, a first embodiment of a tire condition sensing system 1 of the present invention is adapted to be disposed on a vehicle 5 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. Moreover, in the present embodiment, each sensing unit 11 includes, for example, three sensors, wherein each sensor has, for example, a tire pressure sensing component, and is suitable for measuring 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, for example, used as a master sensor 111 included in the sensing unit 11, and the other two of the three sensors are, for example, used as two slave sensors 112 included in the sensing unit 11, respectively. 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 bidirectional wireless transmission manner to perform wireless communication, and the wireless transmission in the embodiment can be implemented by using any existing wireless communication technology, such as one or a combination of more of bluetooth, radio frequency identification (i.e. RFID) and Wi-Fi, but not limited thereto.

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

In this embodiment, the processing unit 12 may be implemented, for example, as a tire condition sensing host, and the processing unit 12 may be adapted to be electrically connected to an on-board computer system 52 included in the vehicle 5, for example. However, in other embodiments, the processing unit 12 can be implemented as the vehicle-mounted computing system 52 itself, or can be included in the vehicle-mounted computing system 52 as a part of the vehicle-mounted computing system 52. More specifically, the processing unit 12 may be installed on the vehicle 5 before the vehicle 5 leaves the factory, or may be installed on the vehicle 5 after the vehicle 5 leaves the factory, for example, and therefore, the practical implementation of the processing unit 12 is not limited to the 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 below the vehicle body 51. The vehicle-mounted computer system 52 is provided in a head portion 511 of the vehicle body 51, for example. 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 in-vehicle computer system 52 by wire, for example, but the invention is not limited thereto.

For the convenience of describing the tire condition sensing system 1 of the present embodiment, the six tires 53 of the vehicle 5 are respectively 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.

As shown in fig. 2, in the present embodiment, the main sensor a1, the sub sensor a2 and the sub sensor a3 of the first sensing unit 11A are respectively and correspondingly disposed on the tire m1, the tire m2 and the tire m3 near the right side of the vehicle 5, and the main sensor B1, the sub sensor B2 and the sub sensor B3 of the second sensing unit 11B are respectively and correspondingly disposed on the tire m4, the tire m5 and the tire m6 near the left side of the vehicle 5.

Therefore, 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 is also 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 is also 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 sensor a2 and the slave sensor a3, and the master sensor b1 is closer to the processing unit 12 than the slave sensor b2 and the slave sensor b 3.

It should be understood that the tire condition sensing system 1 of the present invention can be applied to vehicles with various numbers of tires, and therefore, the vehicle 5 shown in fig. 2 is only used for illustrating the operation of the present embodiment, and is not used to limit the scope of the present invention. In addition, in other embodiments, the number of the sensing units 11 and the number of the slave sensors 112 of each sensing unit 11 can be freely adjusted according to the number of tires of the vehicle on which the tire condition sensing system 1 is installed, and therefore, 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, and 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 b1) and the slave sensors 112 (i.e., the slave sensor a2, the slave sensor a3, the slave sensor b2 and the slave sensor b3) of the present embodiment 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 sufficient that the main sensor 111 and the processing unit 12 are close enough to each other so that the main sensor 111 and the processing unit 12 can successfully communicate with each other wirelessly. On the other hand, for each slave sensor 112 of each sensing unit 11, it is sufficient to ensure that the slave sensor 112 is close enough to the master sensor 111 of the same sensing unit 11 so that the slave sensor 112 and the master sensor 111 of the same sensing unit 11 can successfully communicate wirelessly 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 described in detail below by way of example.

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

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

Specifically, during the first sensing procedure performed by the first sensing unit 11A, the main sensor a1 senses the tire m1 corresponding to itself according to the sensing command to generate a tire condition data corresponding to the tire m 1. In addition, the master sensor a1 also outputs a first control command indicating that the slave sensor a2 and the slave sensor a3 are used for receiving the slave sensor a2 and the slave sensor a3 in a wireless transmission manner according to the sensing command.

Then, after the slave sensor a2 receives the first control command in a wireless transmission manner, the slave sensor a2 senses the tire m2 corresponding to itself 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 the master sensor a1 to receive.

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 tire m3 corresponding to itself according to the first control command to generate the 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 receives the two pieces of 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 pieces of tire condition data respectively corresponding to the tire m1, the tire m2 and the tire m3 in a wireless transmission manner, so that the processing unit 12 receives and obtains the three pieces of tire condition data corresponding to the tire m1, the tire m2 and the tire m 3. In the embodiment, the main sensor a1 can generate an integrated data, for example, and the integrated data includes the three pieces of tire condition data respectively corresponding to the tire m1, the tire m2 and the tire m3, and then the main sensor a1 outputs the integrated data in a wireless transmission manner, so that the processing unit 12 can receive and obtain the three pieces of tire condition data corresponding to the tire m1, the tire m2 and the tire m 3. However, in other embodiments, the main sensor a1 can also output the three pieces of tire condition data corresponding to the tire m1, the tire m2, and the tire m3 one by one for the processing unit 12 to receive, for example, and not limited by the embodiment.

In this way, although the slave sensor a2 and the slave sensor a3 are far away from the processing unit 12, the master sensor a1 can output the two pieces of tire condition data in a wireless transmission manner for the processing unit 12 to receive after receiving the two pieces of tire condition data generated and output by the slave sensor a2 and the slave sensor a3 by the first sensing procedure. In other words, the master sensor a1, in addition to outputting the tire condition data generated by itself (i.e., the tire condition data corresponding to the tire m 1) for receipt by the processing unit 12, can output the two pieces of tire condition data corresponding to the tire m2 and the tire m3, respectively, for receipt by the processing unit 12 in place of the slave sensor a2 and the slave sensor a 3. Therefore, even if the processing unit 12 is far away from the slave sensor a2 and the slave sensor a3 and cannot directly wirelessly communicate with the slave sensor a2 and the slave sensor a3, the processing unit 12 can receive the two pieces 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 command by wireless transmission, the second sensing unit 11B performs another sensing procedure. For convenience of the following description, the sensing procedure performed by the second sensing unit 11B is referred to as a second sensing procedure of the present embodiment.

Specifically, during the second sensing procedure executed by the second sensing unit 11B, the main sensor B1 senses the tire m4 corresponding to itself according to the sensing command to generate a tire condition data corresponding to the tire m 4. In addition, the master sensor b1 also outputs a second control command indicating that the slave sensor b2 and the slave sensor b3 are used for the slave sensor b2 and the slave sensor b3 to receive in a wireless transmission manner according to the sensing command.

Then, after the slave sensor b2 receives the second control command in a wireless transmission manner, the slave sensor b2 senses the tire m5 corresponding to itself according to the second control command to generate the 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 the master sensor b1 to receive.

On the other hand, after the slave sensor b3 receives the second control command in a wireless transmission manner, the slave sensor b3 senses the tire m6 corresponding to itself according to the second control command to generate the 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 master sensor b1 to receive.

After the master sensor b1 generates the tire condition data corresponding to the tire m4 and receives the two pieces of 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 pieces of 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 the embodiment, the main sensor b1 may generate another integrated data including the three pieces of tire condition data respectively corresponding to the tire m4, the tire m5 and the tire m6, and then the main sensor b1 outputs the another integrated data in a wireless transmission manner for the processing unit 12 to receive and obtain the three pieces of tire condition data corresponding to the tire m4, the tire m5 and the tire m 6. However, in other embodiments, the main sensor b1 can also output the three pieces of tire condition data corresponding to the tire m4, the tire m5 and the tire m6 one by one for the processing unit 12 to receive, for example, and not limited by the 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 away from the processing unit 12, by the second sensing procedure, the master sensor b1 can output the two-tire condition data in a wireless transmission manner for the processing unit 12 to receive after receiving the two-tire condition data generated and output by the slave sensor b2 and the slave sensor b 3. In other words, the master sensor b1, in addition to outputting the condition data generated by itself (i.e., the condition data corresponding to the tire m 4) for receipt by the processing unit 12, can output the two condition data corresponding to the tire m5 and the tire m6, respectively, for receipt by the processing unit 12, instead of the slave sensor b2 and the slave sensor b 3. Therefore, even if the processing unit 12 is far away 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 receive the two pieces 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 of the 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. The tire pressure value indicates the tire pressure of the tire 53 corresponding to the tire condition data, and the identifier indicates the sensor generating the tire condition data, for example, and is used for the processing unit 12 to identify which sensor the tire condition data is generated by, in other words, the identifier corresponds to which tire 53 of the vehicle 5 the processing unit 12 identifies the tire condition data corresponds to. It should be noted that, in other embodiments, each sensor further 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 pieces of tire condition data outputted by the main sensor a1 in a wireless transmission manner and respectively corresponding to the tire m1, the tire m2 and the tire m3, and also receives the three pieces of tire condition data outputted by the main sensor b1 in a wireless transmission manner and respectively corresponding to the tire m4, the tire m5 and the tire m6, the processing unit 12 provides at least the tire pressure values of the six pieces of tire condition data respectively corresponding to the six tires 53 to the vehicle-mounted computer system 52, for example, so that the vehicle-mounted 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, a period during which the first sensing unit 11A executes the first sensing program overlaps a period during which the second sensing unit 11B executes the second sensing program, for example, so that, in order to avoid that the first sensing unit 11A and the second sensing unit 11B interfere with each other in the execution process of the first sensing program and the second sensing program, the present embodiment uses, for example, a Frequency Division Multiple Access (FDMA) technique to enable the first sensing unit 11A and the second sensing unit 11B to output the tire condition data by using different frequencies, but not limited thereto.

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

During the first sensing procedure executed 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 to receive through a second frequency 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 through the second frequency channel, and outputs the three tire condition data generated by the master sensor a1 itself, the slave sensor a2 and the slave sensor a3 respectively for the processing unit 12 to receive through the second frequency channel.

On the other hand, during the second sensing procedure executed 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 through a third channel corresponding to a third frequency range, and the master sensor B1 also 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 through 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, in this embodiment, that is, the first frequency range to the third frequency range may not overlap with each other completely. However, in other embodiments, the first frequency range to the third frequency range may be implemented as not completely overlapped with each other, such as 60kHz to 65kHz, 64kHz to 69kHz, and 68kHz to 73kHz, respectively. Generally, the first frequency range to the third frequency range may not overlap with each other completely or completely, and thus the first frequency range to the third frequency range may not overlap with each other completely.

It should be noted that, in the present embodiment, the sensing instruction outputted 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 procedure according to the first instruction portion of the sensing instruction in step S12, and the second sensing unit 11B executes the second sensing procedure according to 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 also be pre-stored in the master sensor a1, the slave sensor a2 and the slave sensor a3, 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, and is not limited by the present embodiment. On the other hand, the second instruction portion of the sensing instruction indicates, for example, a complete operation step of the second sensing program in the present embodiment, and is similar to the first instruction portion of the sensing instruction, and therefore, it is not repeated here, however, in other embodiments, the second instruction portion of the sensing instruction may also be only used as a trigger signal for triggering the second sensing unit 11B to start executing the second sensing program, and is not limited to the present embodiment.

The above is an example of the tire condition transmitting portion of the tire condition sensing method. It should be noted that the tire condition sensing system 1 can automatically execute the tire condition transmission part once when the vehicle 5 is started, for example, so that the vehicle-mounted computer system 52 can perform an initialization detection procedure of the vehicle 5 according to the tire condition data. Alternatively, the tire condition sensing system 1 may also periodically execute the tire condition transmitting portion for multiple times, for example, when the vehicle 5 is started, so that the vehicle-mounted computer system 52 performs the tire condition monitoring process of the vehicle 5 according to the tire condition data.

Next, referring to fig. 1, fig. 2 and fig. 4 together, how the tire condition sensing system 1 performs the abnormality detecting portion of the tire condition sensing method will be described below.

First, in step S21, for each of the master sensor 111 and the slave sensor 112 (hereinafter referred to as "the sensor"), the sensor senses the tire 53 corresponding to itself to obtain a tire pressure value corresponding to the tire 53. Then, the flow advances to step S22.

In step S22, the sensor determines whether the tire pressure value is within a normal tire pressure range, and if the sensor determines that the tire pressure value is within the normal tire pressure range, the process of the abnormality detection section ends, and if the sensor determines that the tire pressure value is not within the normal tire pressure range, the process proceeds to step S23.

In step S23, which follows 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 abnormal condition is met, and wirelessly outputs an abnormal notification corresponding to the tire condition abnormal condition through a fourth frequency channel corresponding to a fourth frequency range, which does not overlap each other completely or completely, for example.

In particular, in the present embodiment, the tire condition transmitting portion and the abnormality detecting portion of the tire condition sensing method are executed by the tire condition sensing system 1, for example, simultaneously, so that the abnormality notification is output through the fourth channel by the sensor, thereby avoiding the abnormality notification from interfering with the first channel to the third channel.

If the sensor is one of the main sensor a1 and the main sensor b1, the abnormal notification indicates the processing unit 12, for example, and is directly received by the processing unit 12 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 the master sensor a1 for receiving by the master sensor a1, and in this case, the master sensor a1 outputs the abnormality notification in a wireless transmission manner through the fourth frequency channel for receiving by the processing unit 12 when receiving the abnormality notification. On the other hand, if the sensor is one of the slave sensor b2 and the slave sensor b3, the abnormality notification indicates the master sensor b1 for receiving by the master sensor b1, and in this case, the master sensor b1 outputs the abnormality notification in a wireless transmission manner through the fourth frequency channel for receiving by the processing unit 12 when receiving the abnormality notification.

Next, the flow advances to step S24.

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

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

It should be noted that, in the present embodiment, the tire condition transmission part of the tire condition sensing method is, for example, used as a resident mechanism of tire condition sensing. However, in other embodiments, the tire condition transmitting portion of the tire condition sensing method may also be, for example, used 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 receiving the tire condition data output by the primary sensors 111 and the secondary sensors 112 in a wireless transmission manner under a normal operation condition, and outputting the tire condition data output by the primary sensors 111 and the secondary 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 executes a tire condition transmission portion of the tire condition sensing method, so that the primary sensors 111 can replace functions 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 resides in the manner of execution of the tire condition transmitting portion 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 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 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 as shown in fig. 5, and after step S12 is finished, the flow proceeds to step S13. That is, in the second embodiment, the second sensing unit 11B can perform the second sensing procedure after the first sensing unit 11A performs the first sensing procedure. In other words, in the second embodiment, the period in which the first sensing unit 11A performs the first sensing procedure and the period in which the second sensing unit 11B performs the second sensing procedure do not overlap each other at all.

By way of example, referring to 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 sets of tire condition data by using Time Division Multiple Access (TDMA). More specifically, in the second embodiment, the sensing instruction outputted by the processing unit 12 includes, for example, the first instruction portion corresponding to the master sensor a1 and the second instruction portion corresponding to the master sensor b1, wherein the first instruction portion includes, for example, a first return time (e.g., "8 hours 0 minutes 0 seconds") corresponding to the master 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 master sensor b1 and later than the first return time. In the second embodiment, the primary sensor a1, for example, will output 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 for a period of time (e.g., 10 seconds) according to the first command, partially at the time of the first return time, for the processing unit 12 to receive. On the other hand, the main sensor b1 will output 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 (e.g. 10 seconds) according to the second instruction, for example, partially when the second return time arrives, so as to be received by the processing unit 12.

In this way, even if the tire condition sensing system 1 of the second embodiment does not utilize the frequency division multiplexing access technique, 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 multiplexing access technique as in the first embodiment.

The above is an example description 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 lies in the manner of execution of the tire condition transmitting portion of the tire condition sensing method.

Referring to fig. 6 in conjunction with fig. 1 and 2, the following describes an example of how the tire condition sensing system 1 of the third embodiment implements the tire condition transmitting portion 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 air pressure reporting command indicates, for example, all of the master sensors 111 and the slave sensors 112, that is, the tire air pressure reporting command is, for example, received by each of the master sensors 111 and the slave sensors 112 in a wireless transmission manner in the third embodiment. It should be noted that the processing unit 12 can be operated by the electric energy of the battery of the vehicle 6, for example, without considering the problem of the electric endurance, so that the processing unit 12 can be configured to perform wireless transmission with higher power and have a longer transmission distance than the master sensors 111 and the slave sensors 112, and it is assumed that each of the master sensors 111 and the slave sensors 112 can directly receive the tire pressure reporting command output by the processing unit 12 in a wireless transmission manner.

After the processing unit 12 outputs the tire pressure reporting command, the process 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 pressure report command in a wireless manner, the sensor senses the tire 53 corresponding to itself to obtain a tire pressure value corresponding to the tire 53, and generates a tire condition data, wherein the tire condition data includes the tire pressure value and a unique identifier 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 in a wireless transmission manner for the processing unit 12 to receive. Also, preferably, the master sensors 111 and the slave sensors 112 can output the tire condition data respectively, for example, by using at least one of a frequency division multiplexing access technique and a time division multiplexing technique. For example, in the case of the time division multiplexing technique, the master sensors 111 and the slave sensors 112 may output the tire condition data generated by themselves one by one in a wireless manner for a period of time (e.g. 5 seconds), and the time point and the duration of outputting 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, 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 from the processing unit 12, for convenience of description, it is assumed that the four pieces of tire condition data generated and output by the four slave sensors 112 cannot be directly received by the processing unit 12, that is, the processing unit 12 only receives the two pieces of tire condition data generated by the master sensor a1 and the master sensor b1 and 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 b3 in step S103.

Subsequently, the flow proceeds to step S104.

In step S104, when the processing unit 12 determines that the 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 sensors 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 the beginning of the processing unit 12 outputting the tire pressure reporting instruction. Moreover, since the processing unit 12 only receives the two tire condition data generated by the master sensor a1 and the master sensor b1 in step S103, 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 in step S104. Next, the flow advances 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, and the first command portion includes, for example, the first return time (e.g., "8 hours 0 minutes 0 seconds") corresponding to the master sensor a1, and the second command portion includes, for example, the second return time "8 hours 0 minutes 15 seconds" corresponding to the master 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 are not received, the first instruction part of the sensing instruction further includes a request for supplementary transmission of the tire condition data indicating the slave sensor a2 and the slave sensor a3 and capable of being identified by the master sensor a1, for example. 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 are not received, the second instruction portion of the sensing instruction further includes a request for supplementary transmission of the tire condition data 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 a preferred embodiment, if the processing unit 12 receives the tire condition data generated by the slave sensor a2 but does not receive the tire condition data generated by the slave sensor a3 in step S103, the tire condition data supplementary transmission request of the first instruction portion only indicates the slave sensor a3 but not the slave sensor a2, that is, the tire condition data supplementary transmission request of the first instruction portion and the second instruction portion only indicates the sensor corresponding to each tire condition data that the processing unit 12 should receive but does not receive in step S103, but 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 part of the sensing instruction, so that the master sensor a1 outputs at least the two pieces of tire condition data generated by the slave sensor a2 and the slave sensor a3 (i.e. the two pieces of tire condition data corresponding to the tire m2 and the tire m3, respectively) in a wireless transmission manner for a period of time (e.g. 10 seconds) when the first return time arrives (e.g. arrives at "8 th 0 min 0S"), for the processing unit 12 to receive. Next, the flow advances 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 at least the two tire condition data generated by the slave sensor B2 and the slave sensor B3 (i.e. the two tire condition data corresponding to the tire m5 and the tire m6, respectively) in a wireless transmission manner for a period of time (e.g. 10 seconds) when the second return time arrives (e.g. arrives at "8 minutes 0 minutes 15 seconds"), for the processing unit 12 to receive. Next, the flow advances to step S14.

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

It should be noted that, in the first sensing program of the third embodiment, the difference from the first embodiment lies in that the master sensor a1 only needs to output the two pieces of 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, nor need to output the tire condition data generated by the master sensor a1 itself and corresponding to the tire m1 again. More specifically, the primary sensor a1 only needs to output the tire condition data that the processing unit 12 did not receive in step S103 in the first sensing procedure of the third embodiment. 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 sense the tire m4 again to generate the tire condition data, nor does the master sensor b1 itself need to output the tire condition data corresponding to the tire m4 again.

The above is an example description of the third embodiment of the present invention.

Referring to fig. 7 in conjunction with fig. 1, a fourth embodiment of the tire condition sensing system 1 is also provided, 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 main sensor 111 and two sub-sensors 112, and for convenience of description, the main sensor 111 of the third sensing unit 11C is used as a main sensor C1 of the fourth embodiment, and the two sub-sensors 112 of the third sensing unit 11C are respectively used as a sub-sensor C2 and a sub-sensor C3 of the present embodiment.

Moreover, the vehicle 6 on which the tire condition sensing system 1 of the fourth embodiment is disposed includes, for example, a vehicle body 61, an on-board computer system 62, and twelve tires 63 disposed under the vehicle body 61. The on-board computer system 62 is, for example, disposed on a head portion 611 of the vehicle body 61, and the processing unit 12 of the fourth embodiment is, for example, also disposed on 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 illustration, nine tires 63 of the vehicle 6 are respectively shown 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 in fig. 7.

Similarly 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 and correspondingly 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 and correspondingly disposed on the tire m4, the tire m5 and the tire m 6. 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 and correspondingly disposed 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 main sensor c1 is closer to the processing unit 12 than the sub sensor c2 and the sub sensor c3, but is farther from the processing unit 12 than the main sensor a1 of the first sensing unit 11A, 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.

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 transmitting portion of the tire condition sensing method.

First, in step S31, the processing unit 12 outputs the sensing instruction by wireless transmission. Unlike the first embodiment, in the fourth embodiment, the sensing instruction output by the processing unit 12 indicates, for example, the main sensor c1 in addition to the main sensor a1 and the main sensor b 1. Subsequently, the flow proceeds to step S32, step S33, and step S34. It should be noted that, in the fourth embodiment, the steps S32, S33 and S34 may be performed simultaneously, for example, but in other implementation forms, the steps S32, S33 and S34 do not necessarily have a fixed sequential relationship.

In step S32, which follows step S31, after the main sensor a1 receives the sensing command outputted by the processing unit 12 through wireless transmission, the first sensing unit 11A executes the first sensing procedure, and the manner of executing the first sensing procedure by the first sensing unit 11A is the same as that of the first embodiment, so that the description thereof is not repeated here.

In step S33, which follows step S31, after the master sensor B1 receives the sensing command in a wireless transmission manner, the second sensing unit 11B executes the second sensing procedure, and the manner of executing the second sensing procedure by the second sensing unit 11B is the same as that of the first embodiment, so that the description thereof is not 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 away from the processing unit 12 and the main sensor a1 is closer to the processing unit 12 than the main sensor c1 in the fourth embodiment, the main sensor a1 outputs the sensing command in a wireless transmission manner, so that it can be avoided that the main sensor c1 is too far away from the processing unit 12 to receive the sensing command generated by the processing unit 12.

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

Specifically, during the third sensing procedure executed by the third sensing unit 11C, the main sensor C1 senses the tire m7 corresponding to itself according to the sensing command to generate a tire condition data corresponding to the tire m 7. In addition, the master sensor c1 also outputs a third control command indicating that the slave sensor c2 and the slave sensor c3 are used for the slave sensor c2 and the slave sensor c3 to receive in a wireless transmission manner according to the sensing command.

Then, 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 the tire condition data corresponding to the tire m8, and outputs the tire condition data corresponding to the tire m8 by wireless transmission for the master sensor c1 to receive.

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 tire m9 corresponding to itself according to the third control command to generate the 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 receives the two pieces of 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 pieces of tire condition data respectively corresponding to the tire m7, the tire m8 and the tire m9 in a wireless transmission manner to be received by the master sensor a1 of the first sensing unit 11A. In the embodiment, the main sensor c1 can generate an integrated data including the three pieces of tire condition data corresponding to the tire m7, the tire m8 and the tire m9, and then the main sensor c1 outputs the integrated data in a wireless transmission manner for the main sensor a1 to receive. However, in other embodiments, the main sensor c1 can also output the three sets of tire condition data corresponding to the tire m7, the tire m8 and the tire m9 one by one for the main sensor a1 to receive, for example, but not limited to this embodiment. It should be noted that the content of each of the condition data in the fourth embodiment is the same as that in the first embodiment, and therefore, the detailed description thereof is omitted.

In step S36 following 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 respectively corresponding to the tire m7, the tire m8 and the tire m9 in a wireless transmission manner, the main sensor a1 outputs the three sets of tire condition data respectively corresponding to the tire m7, the tire m8 and the tire m9 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 generated by itself (i.e., the tire condition data corresponding to the tire m 7), the tire condition data generated by the slave sensor c2 (i.e., the tire condition data corresponding to the tire m 8), and the tire condition data generated by the slave sensor c3 (i.e., the tire condition data corresponding to the tire m 9) to the processing unit 12 through the master sensor a1 of the first sensing unit 11A in a wireless transmission manner. 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 respectively corresponding to the tire m7, the tire m8 and the tire m9 for the processing unit 12 to receive, so as to prevent the processing unit 12 from being too far away from the main sensor C1 to receive the three pieces of tire condition data generated by the third sensing unit 11C.

In step S37 following steps S32, S33 and S36, when the processing unit 12 receives the three pieces of tire condition data generated by the first sensing unit 11A and respectively corresponding to the tire m1, the tire m2 and the tire m3, the three pieces of tire condition data generated by the second sensing unit 11B and respectively corresponding to the tire m4, the tire m5 and the tire m6, and the three pieces of tire condition data generated by the third sensing unit 11C and respectively corresponding to the tire m7, the tire m8 and the tire m9, the processing unit 12 provides, for example, the tire pressure values of the nine pieces of tire condition data respectively corresponding to the tires m1 to m9 to the vehicle-mounted computer system 62, so that the vehicle-mounted 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 reference record.

It should be noted that, in a similar implementation manner of the fourth embodiment, step S34 may be omitted. More specifically, since the processing unit 12 can be configured to perform wireless transmission with higher power and have a longer transmission distance, in a similar implementation manner 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 example description of the fourth embodiment of the present invention. It should be noted that the technical means described in the 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 main sensor 111 of the sensing unit 11 can receive the tire condition data respectively output by the sub-sensors 112 in a wireless transmission manner, and then output the tire condition data generated by the sub-sensors 112 in a wireless transmission manner for the processing unit 12 to receive, that is, the master sensor 111, in addition to outputting the tire condition data generated by itself, can also output the tire condition data generated by the slave sensors 112 for the processing unit 12 to receive instead of the slave sensors 112, and therefore, even if the processing unit 12 is located remotely from the slave sensors 112 and cannot wirelessly communicate directly 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 can receive the tire condition data generated by other sensing units 11 even from other main sensors 111, and output the tire condition data generated by other sensing units 11 in a wireless transmission manner for the processing unit 12 to receive, thereby preventing the processing unit 12 from being too far away from other main sensors 111 to 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 the large vehicle is difficult to be transmitted to the other end, so as to achieve the object of the present invention.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
