Description

[0001] The invention relates to a tire pressure monitor-specific adjustment method.

[0002] A tire pressure monitoring system (TPMS) typically consists of several sensors mounted on the vehicle's tires to monitor the tire pressure of each tire. Tire pressure monitors have been used in some cars in Europe since 1980. In recent years, all new cars in the United States, the European Union, and South Korea have been required to be equipped with tire pressure monitors to ensure driving safety. Similar regulations are expected to be introduced in Japan, the People's Republic of China, and India in the near future. Taiwan also requires all new cars manufactured after July 2016 to be equipped with tire pressure monitors.

[0003] Currently, most tire pressure monitors are wireless. In this case, there is no signal cable between the tire pressure monitor on the tire and a driving computer or windshield display. This means that the tire pressure monitor transmits the measurement results to a driving computer or windshield display via wireless signals.

[0004] If a driving computer or windshield display issues a tire pressure monitor-related warning signal, the driver may mistake it for low tire pressure in a particular tire or a lack of power to a particular tire pressure monitor and therefore drive the car to a specific auto service center. Although the driving computer or windshield display indicates a malfunction, the specific auto service center may mistake it for low tire pressure in a particular tire or a lack of power to a particular tire pressure monitor. In this case, the auto mechanic must use a handheld tester to communicate with the tire pressure monitor.

[0005] But in fact, many drivers don't take their cars to a specific service center for repairs. For example, there may not be a specific service center nearby after the driver sees the corresponding warning signal. In this case, the handheld testers used by mechanics at an unspecified service center often don't match the onboard tire pressure monitor in the car. Therefore, the object of the invention is to allow mechanics to easily communicate with the tire pressure monitors using a handheld tester.

[0006] The document US 2014 / 0165026 A1 discloses methods and systems for programming pressure monitoring sensors.

[0007] The publication DE 11 2012 004 481 T5 describes an improved TPMS tool that can scan optically readable sensor markings.

[0008] Based on the shortcomings of the conventional embodiments, a tire pressure monitor adjustment method is provided that allows auto mechanics to easily communicate with the tire pressure monitors using a handheld tester.

[0009] To solve the problem, a tire pressure monitor-specific adjustment method is provided, which has the following embodiments: A tire pressure monitor specific setting method for setting a test device electrically connected to an image code scanner, the method comprising the steps of: 1. providing a lookup table recording a plurality of image codes, each image code being complementary to at least one factory data set, and at least one factory data set relating to a vehicle, 2. determining, by the image code scanner, an image code among the plurality of image codes to generate a scan result, 3. selecting, by the test device, a communication protocol among a plurality of communication protocols based on the scan result.

[0011] This means that the tire pressure monitor-related setting method according to the invention serves to set a test device electrically connected to an image code scanner and consists of the following steps: 1.

[0012] Providing a lookup table that records a plurality of image codes, wherein each image code is complementary to at least one factory data set and at least one factory data set relates to a vehicle, 2. Determining an image code among the plurality of image codes by the image code scanner to generate a scan result, 3. Selecting a communication protocol among a plurality of communication protocols by the test device based on the scan result.

[0013] The tire pressure monitor-specific setting method according to the invention further comprises calling a first tire pressure monitor of the vehicle using the selected communication protocol.

[0014] The tire pressure monitor-specific setting method according to the invention further comprises reading a feedback from the first tire pressure monitor, wherein the feedback comprises at least a first identification code of the first tire pressure monitor.

[0015] The feedback can include the battery status and the installation position of the first tire pressure monitor.

[0016] The tire pressure monitor-specific setting method according to the invention further comprises writing the first identification code and the selected communication protocol to a second tire pressure monitor.

[0017] The tire pressure monitor-specific setting method according to the invention further comprises reading a first identification code of the first tire pressure monitor and a second identification code of the second tire pressure monitor, writing the first identification code and the selected communication protocol to a third tire pressure monitor, and writing the second identification code and the selected communication protocol to a fourth tire pressure monitor.

[0018] The process of reading the first identification code and the second identification code further comprises calling the first tire pressure monitor using the selected communication protocol, reading a response from the first tire pressure monitor, the response comprising at least a first identification code of the first tire pressure monitor after the first tire pressure monitor has been successfully called, calling the second tire pressure monitor using the selected communication protocol, reading a response from the second tire pressure monitor, the response comprising at least a second identification code of the second tire pressure monitor after the second tire pressure monitor has been successfully called.

[0021] Said setting method further comprises scanning the first identification code on the surface of the first tire pressure monitor using the image code scanner.

[0022] The setting method according to the invention can set a hand-held tester used by the car mechanics based on the vehicle's factory data records so that the car mechanics can easily communicate with the tire pressure monitor in the car using the hand-held tester.

[0023] The invention is not limited to the embodiments, but is variable in many ways within the scope of the disclosure. Fig. 1A View of the vehicle with the tire pressure monitors according to the embodiment of the invention Fig. 1B Block diagram of some functions according to Fig. 1A Fig. 2 Diagram of an embodiment according to the setting method according to the invention Fig. 3 Graphical operating representation of an embodiment according to the invention Fig. 4 Graphical operating representation of another embodiment according to the invention Fig.5 Graphical operating representation of yet another embodiment according to the invention Fig. 6 Graphical operating representation of yet another embodiment according to the invention

[0024] Based on the features and advantages described in detail in the following section, a person skilled in the art can easily recognize and implement the inventive embodiment. Furthermore, a person skilled in the art can easily understand the purpose and advantage of the present invention based on the disclosed content, the claims, and the illustrations. However, it should be noted that these preferred embodiments do not limit the scope of the invention, but serve only to describe the invention. In this context, all new individual and combination features disclosed in the description and / or drawings are considered essential to the invention.

[0025] Fig.1A is a view of the vehicle with the tire pressure monitors according to the embodiment of the invention, while Fig. 1B a block diagram of some functions according to Fig. 1A. According to the embodiment of the invention, vehicles are understood to be motor vehicles with mounted tires, for example, locomotives, cars, tractors, buses, trucks, whose types, tonnage, exhausts and number of passengers are not limited. Fig. 1A and Fig. 1B shows an example with a vehicle (4 seats). Fig. The vehicle 1000 shown in Figure 1A is equipped with four tires 1100, 1200, 1300, and 1400. The tire pressure monitors 2100, 2200, 2300, and 2400 are attached to each tire. The dashed line in Fig.1B indicates that each tire pressure monitor communicates wirelessly with the driving computer 1500 of the vehicle 1000. The installation procedure for the tire pressure monitor is subject to known technology and will not be described further here.

[0026] For example, if the tire pressure of tire 1100 is insufficient, the driving computer 1500 can detect an abnormal tire pressure based on the feedback from the tire pressure monitor 2100 and issue a warning signal. If the battery power of the tire pressure monitor 2100 is about to fail, so that the driving computer 1500 cannot receive the feedback from the tire pressure monitor 2100, the driving computer 1500 will issue a warning signal to the center console of the vehicle 1000. After the driver detects this warning signal, they typically drive the vehicle 1000 to a designated auto service center for repair.

[0027] During the repair, the mechanic must determine whether the problem is due to a malfunction of the tire pressure monitor or insufficient tire pressure. To do this, the mechanic must communicate with the tire pressure monitor using a tester to determine which tire or tire pressure monitor is malfunctioning.

[0028] Tire pressure monitors (2100-2400) are generally divided into integrated tire pressure monitors and air nozzle-mounted tire pressure monitors. An integrated tire pressure monitor is installed inside the tire, while an air nozzle-mounted tire pressure monitor is installed on the tire's air nozzle. Air nozzle-mounted tire pressure monitors are rarely used because they are easily stolen and easily affected or damaged by environmental factors. Integrated tire pressure monitors installed inside the tire make it difficult for auto mechanics to identify the tire pressure monitor types before removing the tire. However, since the tire pressure monitors 2100 ∼ 2400 have to communicate wirelessly with the driving computer 1500 of the vehicle 1000, the communication protocols used by the tire pressure monitors 2100 ∼ 2400 must remain complementary to the driving computer 1500 of the vehicle 1000.The adjustment method according to the invention, however, can evaluate the communication protocols used by the tire pressure monitors based on the factory data set of the vehicle 1000.

[0029] In Fig. Figure 2 shows a diagram of an embodiment according to the adjustment method according to the invention, while Fig.3 is a graphical operating representation of yet another embodiment of the invention. An example using a handheld tester is described below. In other embodiments, the testers attached to the positioning device of the specific car service center can be used. In this way, the car mechanics of the specific car service center can use a lookup table having recorded multiple image codes, each image code remaining complementary to at least one factory data set, and said factory data set relating to a vehicle (step S210). In one embodiment, the lookup table is provided by the supplier of the tire pressure monitors. In another embodiment, the lookup table is processed by the specific car service center. An example of a lookup table according to the invention is shown below. Table I Manufacturer Year of manufacture Vehicle type Image code Manufacturer A 2015 Type 001 first image code 2016 second image code Manufacturer B 2014 Type 002 third image code 2015 2016 fourth image code

[0030] The lookup table lists each manufacturer, year of manufacture, vehicle type, and corresponding image code, with each image code remaining complementary to a communication protocol and / or parameter. In further embodiments, the lookup table can utilize other reference data associated with the factory dataset to allow auto mechanics to easily perform the query. The so-called communication protocol includes the frequency / frequency band used by the wireless signal, modulation modes such as amplitude modulation (AM), frequency modulation (FM), phase modulation (PM), amplitude shift keying (ASK), frequency shift keying (FSK), phase shift keying (PSK), or other suitable modulation modes, packet definitions of radio signals such as field block classification methods, information in each block, parameter definitions of radio signals, etc.

[0031] Based on data such as the manufacturer, year of manufacture, and / or vehicle type of the vehicle 1000, the auto mechanics decide which image code to select to determine a scan result using an image code scanner 2600 electrically connected (or integrated) to the handheld tester 2500 (step S220). The handheld tester then selects a communication protocol from among several communication protocols based on the scan result (step S230). The lookup table can be presented either as a printed document or via a PC screen of a specific auto service center. In one embodiment, the decoded image code is linked to an address complementary to the server of the specific auto service center. Once the image code scanner 2600 electrically connected to the handheld tester 2500 has read the image code, the handheld tester 2500 downloads the communication protocols stored at this address.In another embodiment, the image code is provided only with the code corresponding to the respective communication protocol and / or parameters. Once the image code scanner 2600 has read the image code, the handheld tester 2500 configures itself with this code and / or parameters to perform communication using the communication protocol complementary to the image code.

[0032] The car mechanics of the designated car service center select a corresponding communication protocol using a handheld tester 2500 in the manner described above, namely a communication protocol used by the driving computer 1500 of the vehicle 1000. The selected handheld tester 2500 can wirelessly communicate with the tire pressure monitors 2100 ~ 2400 in a manner similar to the communication with the driving computer 1500 of the vehicle 1000.

[0033] For example, if the driver encounters a tire pressure monitor-related warning signal while driving a vehicle type 001, delivered by manufacturer A in 2016, on a highway, they should pull the vehicle off the highway to ensure driving safety and drive to a nearby designated auto service center of manufacturer A for repairs. If the driver hasn't identified a designated auto service center of manufacturer A nearby, they will normally drive the vehicle to the nearest auto service center.

[0034] In one embodiment, the auto mechanics at the specific auto service center can retrieve the lookup table and determine that the car belongs to vehicle type 001, delivered by manufacturer A in 2016. For example, the type can be determined directly from the appearance of vehicle 1000, from the engine number of vehicle 1000, or from the chassis or body number. The auto mechanics should read the sheet of the lookup table that recorded the first image code BC1 and the second image code BC2, and then read the second image code BC2 using the image code scanner 2600 electrically connected to the handheld tester 2500. The handheld tester 2500 will select the communication protocol complementary to the driving computer 1500 of vehicle type 001, delivered by manufacturer A in 2016.

[0035] In another embodiment, the mechanics at the specific car service center can request the driver's license or service booklet from the driver. After the document is scanned, the computer at the specific car service center can recognize the data such as manufacturer, year of manufacture, and car type using OCR and display the second image code directly on the screen.

[0036] In one embodiment, an auto mechanic can place the handheld tester near tire 1100 of vehicle 1000. The handheld tester 2500 is used to call a tire pressure monitor 2100 mounted on the vehicle 1000 according to a selected communication protocol. Auto mechanics can call any tire pressure monitor. Calling involves the handheld tester 2500 attempting to communicate with a tire pressure monitor 2100. In one embodiment, the handheld tester 2500 will issue a polling signal according to the prescription of a communication protocol. If the battery power of the tire pressure monitor 2100 is sufficient, the tire pressure monitor 2100 will respond to the polling of the handheld tester 2500.Because the handheld tester 2500 can be placed near the tire pressure monitor 2100, the handheld tester 2500 can receive the feedback provided by the tire pressure monitor 2100, although the strength of the signal may be so weak that the driving computer 1500 of the vehicle 1000 cannot evaluate it.

[0037] In one embodiment, the handheld tester 2500 reads the feedback from the tire pressure monitor 2100 after the handheld tester 2500 has received (successfully called) the feedback from the tire pressure monitor 2100. The feedback includes at least the first identification code of the tire pressure monitor 2100. The first identification code can be either the device number of the tire pressure monitor 2100 or a code complementary to a specific field block in the feedback packet of the tire pressure monitor 2100, which allows the drive computer 1500 of the vehicle 1000 to identify the source of the feedback. The handheld tester 2500 can thus record the first identification code of the tire pressure monitor 2100 in internal memory. In another embodiment, the feedback further includes the battery status and the assembly position of the tire pressure monitor 2100.For example, the tire pressure monitor 2100 can send the battery status (%) and the tire build position (on the front left tire, front right tire, rear left tire, or rear right tire) to the handheld tester 2500. In one embodiment, the handheld tester 2500 is provided with a display panel so that the data received by the handheld tester 2500 is displayed so that the car mechanics and / or the driver can easily make an assessment. In another embodiment, the handheld tester 2500 can send the received data wired or wirelessly to the server of the specific car service center so that the computer in the service center or the car mechanics can easily make an assessment.

[0038] In some vehicle types, the tire pressures differ between the front and rear wheels, so the driving computer must detect the tire pressure and the installation position of each tire pressure monitor. For example, due to the weight balance of the vehicle body, the tire pressures of the front wheels of a vehicle type may remain between 35 psi and 37 psi, while the tire pressures of the rear wheels should remain between 32 psi and 33 psi. If the vehicle's driving computer detects the installation position of the tire pressure monitor on the rear left wheel and a tire pressure of 33 psi, the driving computer judges the tire pressure to be OK. If the vehicle's driving computer detects the installation position of the tire pressure monitor on the front left wheel and a tire pressure of 34 psi, the driving computer judges the tire pressure to be too low and therefore issues a warning signal.

[0039] For example, if the auto mechanics determine that the warning signal output from the driving computer 1500 is due to a power failure of the tire pressure monitor 2200 among the tire pressure monitors 2100 ~ 2400, the auto mechanics can retrieve another tire pressure monitor 3200 from the warehouse of the specific auto service center for replacement. Since the tire pressure monitor 3200 is not yet configured to replace the tire pressure monitor 2200, and therefore the feedback from the tire pressure monitor 3200 cannot yet be evaluated by the driving computer 1500, the driving computer 1500 cannot receive the feedback from the tire pressure monitor 3200. In this context, Fig.4 shows a graphical operating representation of yet another embodiment of the invention. The setting method according to the invention further includes writing the identification code of the tire pressure monitor 2200 and the selected communication protocol (a communication protocol complementary to the second image code) to the tire pressure monitor 3200. In this case, the driving computer 1500 can evaluate the feedback when the tire pressure monitor 3200 outputs feedback based on the selected communication protocol. Since the identification code of the tire pressure monitor 2200 is already written on the tire pressure monitor 3200 and the feedback from the tire pressure monitor 3200 therefore includes the identification code of the tire pressure monitor 2200, the driving computer 1500 will evaluate the tire pressure monitor 3200 as the tire pressure monitor 2200. In this way, the tire pressure monitors can be replaced by an auto service center.With the above-mentioned setting method, both a specific auto service center and an unspecified auto service center can replace any tire pressure monitor. This eliminates the need for a specific auto service center to maintain a specific tire pressure monitor inventory for each manufacturer, year of manufacture, and vehicle type. The pressure on the auto service center's inventory is thus reduced. The handheld tester 2500 in the present embodiment can be considered a burner or adjuster for the tire pressure monitors. In one embodiment, the handheld tester 2500 can also write the received assembly position data of the tire pressure monitor 2200 to a tire pressure monitor 3200. The operation is similar to that described above and will not be described further here.

[0040] In one embodiment, the auto mechanic is supposed to have called each tire pressure monitor 2100 ∼ 2400 with the handheld tester 2500 before setting a tire pressure monitor 3200. In this context, the handheld tester 2500 has determined the identification code of each tire pressure monitor. In the present embodiment, when setting the tire pressure monitor 3200, the handheld tester 2500 not only writes the identification code of the tire pressure monitor 2200 to the tire pressure monitor 3200, but also the identification codes of the tire pressure monitors 2100, 2300, and 2400 to the tire pressure monitor 3200. The next time the driver takes the vehicle 1000 to an auto service center for repair, the auto mechanics there can determine all the tire pressure monitor identification codes just by reading the tire pressure monitor 3200.

[0041] In another embodiment, the actual identification code of the tire pressure monitor 3200 may include the delivery date, storage period, and other important data of the tire pressure monitor 3200. Therefore, the handheld tester 2500 may read the identification code of the tire pressure monitor 3200 before setting the tire pressure monitor 3200. The identification codes of the tire pressure monitor 2200 and the tire pressure monitor 3200 may be rewritten to the tire pressure monitor 3200. The next time the driver takes the vehicle 1000 to an auto service center for repair, the auto mechanics there can determine all the tire pressure monitor identification codes simply by reading the tire pressure monitor 3200.

[0042] In a further embodiment of the invention, tire pressure monitors 2100, 2300, and 2400 may also fail soon if the battery of tire pressure monitor 2200 fails soon, since all tire pressure monitors are installed in vehicle 1000 at approximately the same time. Therefore, the driver can have all tire pressure monitors replaced at once. In view of this need, the setting method according to the invention also enables setting of all tire pressure monitors in the batch and comprises the following step after step S230: removing the tire pressure monitors 2100 ~ 2400 at once from the tires 1100 ~ 1400 of the vehicle 1000. Thereafter, the car mechanics read the identification codes from the tire pressure monitors 2100, 2200, 2300 and 2400 using the hand-held tester 2500. The reading process of the identification code of each tire pressure monitor is the same as the one mentioned above, with each tire pressure monitor sending a response according to the selected communication protocol.

[0043] In this context, Fig. 5 shows a graphical operating representation of yet another embodiment of the invention. With reference to Fig. 5, the surface of the tire pressure monitor 2100 is provided with an identification code (one-dimensional barcode or QR code). The remaining tire pressure monitors 2200 ∼ 2400 each also have their own identification code. The identification codes can be attached to the surface of a tire pressure monitor with adhesive tape or applied to the surface of a tire pressure monitor by laser engraving or chemical etching. In this embodiment, the tire pressure monitors can be integrated tire pressure monitors or tire pressure monitors mounted on the air nozzle. Integrated tire pressure monitors are protected against external influences and are therefore preferred.

[0044] In the present embodiment, the battery of the tire pressure monitor 2100 may fail completely if the handheld tester 2500 fails to call the tire pressure monitor 2100 successfully. If the tire pressure monitor 2100 is an integrated tire pressure monitor, the auto mechanic can remove the tire 1100 and detach the tire pressure monitor. Then, the identification code on the surface of the tire pressure monitor 2100 can be scanned using the image code scanner 2600 or other scanning device electrically connected to the handheld tester 2500. If the tire pressure monitor 2100 is an air nozzle-mounted tire pressure monitor, the auto mechanic does not need to remove the tire 1100, but can directly scan the identification code on the surface of the tire pressure monitor 2100 using the image code scanner 2600 or other scanning device electrically connected to the handheld tester 2500.If necessary, the car mechanic can scan the identification code of a tire pressure monitor using the 2600 image code scanner, not necessarily in the event that the tire pressure monitors 2100 ∼ 2400 will soon be without power.

[0045] In Fig. Figure 6 shows a graphical operating diagram of yet another embodiment of the invention. After reading the identification codes of all tire pressure monitors, the auto mechanic can prepare the tire pressure monitors 3100-3400 and set the handheld tester 2500 so that the handheld tester 2500 writes the identification codes of the tire pressure monitors 2100-2400 and the selected communication protocol to the tire pressure monitor 3100-3400.

[0046] In one embodiment, the tire pressure monitors 3100 ∼ 3400 are each configured with a standardized communication protocol, which may be specified by the tire pressure monitor supplier and therefore remains different from the communication protocol in the driving computer 1500 of the vehicle 1000. When configuring the tire pressure monitors 3100 ∼ 3400 using the handheld tester, the handheld tester will send a query to the tire pressure monitors 3100 ∼ 3400 according to the standard communication protocol, so that the tire pressure monitors 3100 ∼ 3400 each send a response. The response here, for example, from the tire pressure monitor 3100 includes the identification code of the tire pressure monitor 3100.

[0047] In one embodiment, the handheld tester will send a query corresponding to the standard communication protocol until the identification codes of all four tire pressure monitors 3100 ∼ 3400 are determined, since the identification codes of four tire pressure monitors 2100 ∼ 2400 are already available to the handheld tester.

[0048] The handheld tester will then send the commands, the communication protocol selected by the second image code, and the identification code of the tire pressure monitor 2100 to the tire pressure monitor 3100 according to the standard communication protocol and the identification code of the tire pressure monitor 3100. The selected communication protocol and the identification code of the tire pressure monitor 2100 are written to the tire pressure monitor 3100 for storage. The tire pressure monitor 3100 will then send an acknowledgement signal to the handheld tester. The handheld tester then sends a restart signal back to the tire pressure monitor 3100. The tire pressure monitor 3100 will restart according to the identification code of the tire pressure monitor 2100 and the selected communication protocol. In this way, the tire pressure monitors 3100 ~ 3400 can sequentially replace the tire pressure monitors 2100 ~ 2400 using the handheld tester.

[0049] As mentioned above, the setting method according to the invention can determine a communication protocol used by a vehicle's driving computer by reading an image code and then set up a test device based on this communication protocol so that the test device can communicate with a tire pressure monitor. This improves the work efficiency of auto mechanics.
