[0064] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0065] In order to make the purpose, technical solutions and advantages of the present application clearer, specific embodiments will be described below in conjunction with the accompanying drawings.

[0066] See also Figure 1 , which shows an implementation flow chart of the off-line learning method of the tire pressure monitoring system (TPMS) of the vehicle provided in an embodiment of the present application. The executor of the off-line learning method of the tire pressure monitoring system of the vehicle may be an off-line detection device (End of line, EOL).

[0067] Each tire of the vehicle has a corresponding tire pressure sensor, and each tire corresponds to at least one antenna for reading the ID of the corresponding tire pressure sensor.

[0068] Each tire of the vehicle has a corresponding tire pressure sensor for detecting tire pressure, temperature and other information of the corresponding tire. Each tire of the vehicle corresponds to at least one antenna for reading the ID of the tire pressure sensor of the tire. The distance from each antenna to the outer edge of the corresponding tire is less than or equal to the first preset distance, and the maximum detection distance of the antenna is less than or equal to the second preset distance. The first preset distance is less than the second preset distance. The values ​​of the first preset distance and the second preset distance can be set according to actual needs. For example, the first preset distance can be 50 mm, the second preset distance can be 300 mm, and so on.

[0069] When arranging antennas, it is necessary to ensure that the tire pressure sensor whose ID is to be read is within its maximum detection distance. If the distance between tires is far, one antenna can be used to detect the ID of the tire pressure sensor of one tire, that is, the antenna and the tire correspond one to one. If the distance between tires is close, for example, two tires are installed at each end of an axle. Since the antenna has a certain detection range, it is impossible to achieve a one-to-one correspondence between the antenna and the tire. Then, one antenna can be used to detect the ID of the tire pressure sensor of at least two adjacent tires, and the information detected by adjacent antennas is partially overlapped. For example, one antenna detects the ID of the tire pressure sensor of tire A and tire B, and another antenna detects the ID of the tire pressure sensor of tire A and tire C, and so on. The ID of the tire pressure sensor of each tire is subsequently obtained through corresponding calculations.

[0070] The ID of the tire pressure sensor can be used to uniquely identify the tire pressure sensor and is the identification code of the tire pressure sensor. The tire pressure sensor and its corresponding tire are bound to each other. By learning the ID of each tire pressure sensor, this embodiment can detect the information of the corresponding tire through the tire pressure sensor when the vehicle is used later, and determine which tire's information is detected through the ID of the tire pressure sensor.

[0071] The offline learning method of the tire pressure monitoring system of the above vehicle is described in detail as follows:

[0072] In S101, each antenna is controlled to read the ID of the tire pressure sensor of the corresponding tire, and the read data sent by each antenna is received.

[0073] In this embodiment, the offline detection device sends a read instruction to each antenna when starting the offline learning process of the TPMS. After receiving the read instruction, each antenna transmits a low-frequency signal, and after the tire pressure sensor within its detection range receives the low-frequency signal, it feeds back its own ID. After receiving the data fed back by the corresponding tire pressure sensor, the antenna feeds back the received data (i.e., the read data of the antenna) to the offline detection device.

[0074] In the above S101, the above controlling each antenna to read the ID of the tire pressure sensor of the corresponding tire may include:

[0075] When receiving the offline learning instruction of TPMS, each antenna is controlled to read the ID of the tire pressure sensor of the corresponding tire.

[0076] The assembled vehicle will enter the corresponding offline inspection station. The staff will use visual marks to determine whether the vehicle is in place, that is, whether it has entered the above offline inspection station. If the vehicle is not in place, the vehicle will be controlled to enter the corresponding offline inspection station. After confirming that the vehicle is in place, the offline learning instruction of TPMS is input to the offline inspection equipment. For example, a start button is set on the offline inspection equipment. By pressing the start button, it means that the offline learning instruction of TPMS is input, and so on.

[0077] When receiving the offline learning instruction of the TPMS, the offline detection device starts to control each antenna to read the ID of the tire pressure sensor of the corresponding tire.

[0078] In S102 , the ID of each tire pressure sensor is determined based on the received read data of each antenna.

[0079] The offline detection equipment can determine the ID of the tire pressure sensor of each tire by reading the data received from each antenna. Since there may be a situation where the antenna does not read the ID of the tire pressure sensor of the corresponding tire, the ID of one or several tire pressure sensors may not be determined by reading the data received from each antenna.

[0080] In S103, after the IDs of the tire pressure sensors corresponding to all tires of the vehicle are determined, the IDs of the tire pressure sensors corresponding to each tire are written into the corresponding controller of the vehicle.

[0081] After the IDs of the tire pressure sensors corresponding to all tires of the vehicle are determined, that is, after the IDs of the tire pressure sensors corresponding to all tires of the vehicle are obtained, the offline detection equipment writes the ID of the tire pressure sensor corresponding to each tire into the corresponding controller of the vehicle for subsequent use.

[0082] In this embodiment, each tire of the vehicle has a corresponding tire pressure sensor, and each tire corresponds to at least one antenna for reading the ID of the corresponding tire pressure sensor; each antenna is controlled to read the ID of the tire pressure sensor of the corresponding tire, and the read data sent by each antenna is received; the ID of each tire pressure sensor is determined based on the read data received from each antenna; and after the IDs of the tire pressure sensors corresponding to all tires of the vehicle are determined, the ID of the tire pressure sensor corresponding to each tire is written into the corresponding controller of the vehicle, thereby realizing automatic learning of the IDs of each tire pressure sensor of the tire pressure monitoring system of the vehicle without the need for manual handheld tools to perform detection in sequence, which can shorten the offline learning time of the tire pressure monitoring system, improve the offline learning efficiency of the tire pressure monitoring system, reduce the workload of staff, and save a lot of manpower.

[0083] In some embodiments, see Figure 2 The vehicle includes a first tire 21 and a second tire 22 located at both ends of a first front axle, a third tire 23 and a fourth tire 24 located at the left axle head of the first rear axle, a fifth tire 25 and a sixth tire 26 located at the right axle head of the first rear axle, a seventh tire 27 and an eighth tire 28 located at the left axle head of the second rear axle, and a ninth tire 29 and a tenth tire 20 located at the second rear axle; the first tire 21 corresponds to a first antenna 211, the second tire 22 corresponds to a second antenna 212, the third tire 23 corresponds to a third antenna 213 and a fourth antenna 214, the fourth tire 24 corresponds to a fourth antenna 214, the fifth tire 25 corresponds to a fifth antenna 215, the sixth tire 26 corresponds to a fifth antenna 215 and a sixth antenna 216, the seventh tire 27 corresponds to a third antenna 213 and a seventh antenna 217, the eighth tire 28 corresponds to a seventh antenna 217, the ninth tire 29 corresponds to an eighth antenna 218, and the tenth tire 20 corresponds to a sixth antenna 216 and an eighth antenna 218;

[0084] In the above S101, controlling each antenna to read the ID of the tire pressure sensor of the corresponding tire includes:

[0085] Controlling the first antenna 211 to read the ID of the tire pressure sensor of the first tire 21;

[0086] Controlling the second antenna 212 to read the ID of the tire pressure sensor of the second tire 22;

[0087] Control the third antenna 213 to read the IDs of the tire pressure sensors of the third tire 23 and the seventh tire 27;

[0088] Control the fourth antenna 214 to read the IDs of the tire pressure sensors of the third tire 23 and the fourth tire 24;

[0089] Control the fifth antenna 215 to read the IDs of the tire pressure sensors of the fifth tire 25 and the sixth tire 26;

[0090] Control the sixth antenna 216 to read the IDs of the tire pressure sensors of the sixth tire 26 and the tenth tire 20;

[0091] Control the seventh antenna 217 to read the IDs of the tire pressure sensors of the seventh tire 27 and the eighth tire 28;

[0092] The eighth antenna 218 is controlled to read the IDs of the tire pressure sensors of the ninth tire 29 and the tenth tire 20 .

[0093] Accordingly, the above S102 may include:

[0094] Determine the ID of the tire pressure sensor of the first tire 21 according to the read data of the first antenna 211;

[0095] Determine the ID of the tire pressure sensor of the second tire 22 according to the read data of the second antenna 212;

[0096] Determine the ID of the tire pressure sensor of the third tire 23 and the ID of the tire pressure sensor of the fourth tire 24 according to the read data of the third antenna 213 and the read data of the fourth antenna 214;

[0097] Determine the ID of the tire pressure sensor of the fifth tire 25 and the ID of the tire pressure sensor of the sixth tire 26 according to the read data of the fifth antenna 215 and the read data of the sixth antenna 216;

[0098] Determine the ID of the tire pressure sensor of the seventh tire 27 and the ID of the tire pressure sensor of the eighth tire 28 according to the read data of the third antenna 213 and the read data of the seventh antenna 217;

[0099] Based on the read data of the sixth antenna 216 and the read data of the eighth antenna 218 , the ID of the tire pressure sensor of the ninth tire 29 and the ID of the tire pressure sensor of the tenth tire 20 are determined.

[0100] This embodiment performs offline learning of TPMS for 6×4 vehicles. The 6×4 vehicle includes a front axle and two rear axles. In this embodiment, the front axle is referred to as the first front axle, and the two rear axles are referred to as the first rear axle and the second rear axle. Figure 2 As shown, a tire is installed at each end of the first front axle, namely, a first tire 21 and a second tire 22. Two tires are installed at each end of the first rear axle and the second rear axle, a third tire 23 and a fourth tire 24 are installed on the left side of the first rear axle, a fifth tire 25 and a sixth tire 26 are installed on the right side of the first rear axle, a seventh tire 27 and an eighth tire 28 are installed on the left side of the second rear axle, and a ninth tire 29 and a tenth tire 20 are installed on the right side of the second rear axle.

[0101] See also Figure 2 Since the two tires of the first front axle are far away from other tires, the two tires of the first front axle each have a one-to-one corresponding antenna, that is, the first tire 21 corresponds to the first antenna 211, and the first antenna 211 only reads the ID of the tire pressure sensor corresponding to the first tire 21, and the second tire 22 corresponds to the second antenna 212, and the second antenna 212 only reads the ID of the tire pressure sensor corresponding to the second tire 22. Since the first rear axle and the second rear axle are close to each other, and two tires are installed at each end, and the antenna has a certain detection range, one-to-one corresponding detection cannot be achieved. Therefore, the IDs of the tire pressure sensors of two adjacent tires are read by one antenna, and the antennas are arranged in a manner that the information read by the adjacent antennas partially overlaps, that is, the third antenna 213 reads the ID of the tire pressure sensor of the third tire 23 and the ID of the tire pressure sensor of the seventh tire 27, the fourth antenna 214 reads the ID of the tire pressure sensor of the third tire 23 and the ID of the tire pressure sensor of the fourth tire 24, the fifth antenna 215 reads the ID of the tire pressure sensor of the fifth tire 25 and the ID of the tire pressure sensor of the sixth tire 26, the sixth antenna 216 reads the ID of the tire pressure sensor of the sixth tire 26 and the ID of the tire pressure sensor of the tenth tire 20, the seventh antenna 217 reads the ID of the tire pressure sensor of the seventh tire 27 and the ID of the tire pressure sensor of the eighth tire 28, and the eighth antenna 218 reads the ID of the tire pressure sensor of the ninth tire 29 and the ID of the tire pressure sensor of the tenth tire 20.

[0102] After receiving the read command sent by the offline detection device, the first antenna 211 to the eighth antenna 218 read the ID of the tire pressure sensor of the tire within its detection range, and feed back the read data to the offline detection device. The offline detection device determines the ID of the tire pressure sensor corresponding to each tire based on the read data fed back by the first antenna 211 to the eighth antenna 218.

[0103] for Figure 2In the 6×4 vehicle shown, the read data fed back by the first antenna 211 is the ID of the tire pressure sensor of the first tire 21 , and the read data fed back by the second antenna 212 is the ID of the tire pressure sensor of the second tire 22 .

[0104] In some embodiments, determining the ID of the tire pressure sensor of the third tire and the ID of the tire pressure sensor of the fourth tire according to the read data of the third antenna and the read data of the fourth antenna includes:

[0105] Perform an AND operation on the data read by the third antenna and the data read by the fourth antenna to obtain the ID of the tire pressure sensor of the third tire;

[0106] The data obtained by performing a non-operation on the read data of the third antenna is ANDed with the data read by the fourth antenna to obtain the ID of the tire pressure sensor of the fourth tire.

[0107] Since the third antenna 213 reads the ID of the tire pressure sensor of the third tire 23 and the ID of the tire pressure sensor of the seventh tire 27, and the fourth antenna 214 reads the ID of the tire pressure sensor of the third tire 23 and the ID of the tire pressure sensor of the fourth tire 24, the same ID in the read data of the third antenna 213 and the read data of the fourth antenna 214 is the ID of the tire pressure sensor of the third tire 23. For example, the read data of the third antenna 213 and the read data of the fourth antenna 214 can be ANDed to obtain the tire pressure sensor ID of the third tire 23. The ID of the tire pressure sensor of the third tire 23 is obtained by performing a non-operation on the read data of the third antenna 213, and the read data of the fourth antenna 214 is obtained by performing a non-operation on the read data of the third antenna 213. The read data of the fourth antenna 214 is obtained by performing a non-operation on the read data of the third antenna 213, and the obtained data is then subjected to a non-operation on the read data of the fourth antenna 214 to obtain the ID of the tire pressure sensor of the fourth tire 24, that is, the read data of the third antenna 213 && the read data of the fourth antenna 214 = the ID of the tire pressure sensor of the fourth tire 24, wherein, ! indicates a non-operation.

[0108] In some embodiments, the step of determining the ID of the tire pressure sensor of the fifth tire and the ID of the tire pressure sensor of the sixth tire according to the read data of the fifth antenna and the read data of the sixth antenna includes:

[0109] Perform an AND operation on the data read by the fifth antenna and the data read by the sixth antenna to obtain the ID of the tire pressure sensor of the sixth tire;

[0110] The data obtained by performing a non-operation on the read data of the sixth antenna is ANDed with the data read by the fifth antenna to obtain the ID of the tire pressure sensor of the fifth tire.

[0111] Similarly, since the fifth antenna 215 reads the ID of the tire pressure sensor of the fifth tire 25 and the ID of the tire pressure sensor of the sixth tire 26, and the sixth antenna 216 reads the ID of the tire pressure sensor of the sixth tire 26 and the ID of the tire pressure sensor of the tenth tire 20, the same ID in the read data of the fifth antenna 215 and the read data of the sixth antenna 216 is the ID of the tire pressure sensor of the sixth tire 26. For example, the read data of the fifth antenna 215 and the read data of the sixth antenna 216 can be ANDed to obtain the ID of the tire pressure sensor of the sixth tire 26, that is, the read data of the fifth antenna && the read data of the sixth antenna = the ID of the tire pressure sensor of the sixth tire 26; in the read data of the fifth antenna 215, the ID other than the same ID in the read data of the sixth antenna 216 is the ID of the tire pressure sensor of the fifth tire 25. For example, the read data of the sixth antenna 216 can be firstly non-operated, and the obtained data can be ANDed with the read data of the fifth antenna 215 to obtain the ID of the tire pressure sensor of the fifth tire 25, that is,! The read data of the sixth antenna 216 &&the read data of the fifth antenna 215 =the ID of the tire pressure sensor of the fifth tire 25 .

[0112] In some embodiments, the step of determining the ID of the tire pressure sensor of the seventh tire and the ID of the tire pressure sensor of the eighth tire according to the read data of the third antenna and the read data of the seventh antenna includes:

[0113] Perform an AND operation on the data read by the third antenna and the data read by the seventh antenna to obtain the ID of the tire pressure sensor of the seventh tire;

[0114] The data obtained by performing a non-operation on the read data of the third antenna is ANDed with the data read by the seventh antenna to obtain the ID of the tire pressure sensor of the eighth tire.

[0115] Since the third antenna 213 reads the ID of the tire pressure sensor of the third tire 23 and the ID of the tire pressure sensor of the seventh tire 27, and the seventh antenna 217 reads the ID of the tire pressure sensor of the seventh tire 27 and the ID of the tire pressure sensor of the eighth tire 28, the same ID in the read data of the third antenna 213 and the read data of the seventh antenna 217 is the ID of the tire pressure sensor of the seventh tire 27. For example, the read data of the third antenna 213 and the read data of the seventh antenna 217 can be ANDed to obtain the tire pressure sensor of the seventh tire 27. The ID of the tire pressure sensor of the eighth tire 28 is obtained by performing a non-operation on the read data of the third antenna 213, and then performing an AND operation on the obtained data with the read data of the seventh antenna 217 to obtain the ID of the tire pressure sensor of the eighth tire 28, that is, the read data of the third antenna 213 && the read data of the seventh antenna 217 = the ID of the tire pressure sensor of the eighth tire 28.

[0116] In some embodiments, the step of determining the ID of the tire pressure sensor of the ninth tire and the ID of the tire pressure sensor of the tenth tire according to the read data of the sixth antenna and the read data of the eighth antenna includes:

[0117] Perform an AND operation on the data read by the sixth antenna and the data read by the eighth antenna to obtain the ID of the tire pressure sensor of the tenth tire;

[0118] The data obtained by performing a non-operation on the read data of the sixth antenna is ANDed with the data read by the eighth antenna to obtain the ID of the tire pressure sensor of the ninth tire.

[0119] Since the sixth antenna 216 reads the ID of the tire pressure sensor of the sixth tire 26 and the ID of the tire pressure sensor of the tenth tire 20, and the eighth antenna 218 reads the ID of the tire pressure sensor of the ninth tire 29 and the ID of the tire pressure sensor of the tenth tire 20, the same ID in the read data of the sixth antenna 216 and the read data of the eighth antenna 218 is the ID of the tire pressure sensor of the tenth tire 20. For example, the read data of the eighth antenna 218 and the read data of the sixth antenna 216 can be ANDed to obtain the ID of the tire pressure sensor of the tenth tire 20, that is, the read data of the eighth antenna 218 && the read data of the sixth antenna 216 = the ID of the tire pressure sensor of the tenth tire 20; in the read data of the eighth antenna 218, the ID other than the same ID in the read data of the sixth antenna 216 is the ID of the tire pressure sensor of the ninth tire 29. For example, the read data of the sixth antenna 216 can be firstly non-operated, and the obtained data can be ANDed with the read data of the eighth antenna 218 to obtain the ID of the tire pressure sensor of the ninth tire 29, that is,! The read data of the sixth antenna 216 &&the read data of the eighth antenna 218 =the ID of the tire pressure sensor of the ninth tire 29 .

[0120] For a 6×4 vehicle, if a handheld tool is used to read the ID of each sensor in turn, the total time required to read the sensor ID, the time to walk around the vehicle, and the time to write the ID is about 320 seconds, which seriously affects the production cycle. However, using the method provided in the embodiment of the present application, it only takes about 80 seconds, which can shorten a lot of time and improve vehicle production efficiency.

[0121] In some embodiments, see Figure 3 For a vehicle with four tires, the vehicle includes an eleventh tire 31 and a twelfth tire 32 located at both ends of the second front axle and a thirteenth tire 33 and a fourteenth tire 34 located at both ends of the third rear axle; the eleventh tire 31 corresponds to the ninth antenna 311, the twelfth tire 32 corresponds to the tenth antenna 312, the thirteenth tire 33 corresponds to the eleventh antenna 313, and the fourteenth tire 34 corresponds to the twelfth antenna 314.

[0122] Accordingly, in the above S101, controlling each antenna to read the ID of the tire pressure sensor of the corresponding tire includes:

[0123] controlling the ninth antenna 311 to read the ID of the tire pressure sensor of the eleventh tire 31;

[0124] controlling the tenth antenna 312 to read the ID of the tire pressure sensor of the twelfth tire 32;

[0125] controlling the eleventh antenna 313 to read the ID of the tire pressure sensor of the thirteenth tire 33;

[0126] The twelfth antenna 314 is controlled to read the ID of the tire pressure sensor of the fourteenth tire 34 .

[0127] Accordingly, the above S102 may include:

[0128] Determine the ID of the tire pressure sensor of the eleventh tire 31 according to the read data of the ninth antenna 311;

[0129] Determine the ID of the tire pressure sensor of the twelfth tire 32 according to the read data of the tenth antenna 312;

[0130] Determine the ID of the tire pressure sensor of the thirteenth tire 33 according to the read data of the eleventh antenna 313;

[0131] Based on the read data of the twelfth antenna 314 , the ID of the tire pressure sensor of the fourteenth tire 34 is determined.

[0132] This embodiment performs offline learning of TPMS for a vehicle with four tires. A vehicle with four tires includes a front axle and a rear axle. In this embodiment, the front axle is referred to as the second front axle, and the rear axle is referred to as the third rear axle. Figure 3 As shown, a tire is installed at each end of the second front axle, namely the eleventh tire 31 and the twelfth tire 32. A tire is installed at each end of the third rear axle, namely the thirteenth tire 33 and the fourteenth tire 34.

[0133] See also Figure 3 Since the distance between the eleventh tire 31 to the fourteenth tire 34 is relatively far, an antenna can be set for each tire, that is, the tires correspond to the antennas one by one, and one antenna only reads the ID of the tire pressure sensor of the corresponding tire. The ID of the tire pressure sensor of the tire corresponding to the antenna can be determined through the read data of each antenna.

[0134] It should be noted that, in order to distinguish it from the aforementioned 6×4 vehicle, for the vehicle with four tires, its front axle is called the second front axle, its rear axle is called the third rear axle, its individual tires are respectively called the eleventh tire 31, the twelfth tire 32, the thirteenth tire 33 and the fourteenth tire 34, and the antennas installed thereon are respectively called the ninth antenna 311, the tenth antenna 312, the eleventh antenna 313 and the twelfth antenna 314.

[0135] Figure 2 and Figure 3 In FIG. 1 , the dotted box corresponding to each antenna is the detection range of the corresponding antenna.

[0136] In some embodiments, in the above S103, writing the ID of the tire pressure sensor corresponding to each tire into the corresponding controller of the vehicle includes:

[0137] Write the ID of the tire pressure sensor corresponding to each tire into the corresponding controller of the vehicle through the vehicle's on-board diagnostic system OBD (On Board Diagnostic) interface and unified diagnostic service UDS (Unified Diagnostic Services); or,

[0138] The ID of the tire pressure sensor corresponding to each tire is transmitted to the cloud, so that the vehicle's remote communication terminal TBox (Telematics Box) obtains the ID of the tire pressure sensor corresponding to each tire from the cloud, and writes the ID of the tire pressure sensor corresponding to each tire into the corresponding controller of the vehicle through the unified diagnostic service UDS.

[0139] In this embodiment, the ID of the tire pressure sensor corresponding to each tire can be written into the corresponding controller of the vehicle in two ways.

[0140] See also Figure 4 The first method is that the EOL device writes the ID of the tire pressure sensor corresponding to each tire into the corresponding controller of the vehicle through the vehicle's OBD interface and UDS diagnostic service. Among them, the OBD interface can send the ID of the tire pressure sensor corresponding to each tire to the corresponding controller of the vehicle through GW (Gateway) or CEM (Central Electronic Module).

[0141] See also Figure 5 The second method is that the EOL device sends the ID of the tire pressure sensor corresponding to each tire to the cloud through wireless communication. The vehicle's TBox can obtain the ID of the tire pressure sensor corresponding to each tire from the cloud through wireless communication, and write the ID of the tire pressure sensor corresponding to each tire to the corresponding controller of the vehicle through the UDS diagnostic service. Among them, the TBox can send the ID of the tire pressure sensor corresponding to each tire to the corresponding controller of the vehicle through the GW or CEM. The TBox can also be called a vehicle networking unit.

[0142] The corresponding controller of the vehicle is a separate controller in the TPMS or a regional controller (Vehicle Integrated Unit, VIU) of the vehicle.

[0143] In some embodiments, after S102, the off-line learning method of the tire pressure monitoring system of the vehicle further includes:

[0144] If there is a target tire whose tire pressure sensor ID is not determined, controlling the antenna associated with the target tire to read the ID of the tire pressure sensor of the corresponding tire, and re-determining the ID of the tire pressure sensor of the target tire based on the data re-read by the antenna associated with the target tire;

[0145] If the ID of the tire pressure sensor of the target tire still cannot be determined, repeatedly executing the steps of controlling the antenna associated with the target tire to read the ID of the tire pressure sensor of the corresponding tire, and re-determining the ID of the tire pressure sensor of the target tire based on the data re-read by the antenna associated with the target tire, until the ID of the tire pressure sensor of the target tire is determined, or the number of times of re-determining the ID of the tire pressure sensor of the target tire reaches a preset number;

[0146] If the number of times of re-determining the ID of the tire pressure sensor of the target tire reaches a preset number and the ID of the tire pressure sensor of the target tire is still not determined, it is prompted that the ID learning of the tire pressure sensor has failed.

[0147] The target tire whose tire pressure sensor ID is not determined refers to the target tire whose tire pressure sensor ID is not obtained by the offline detection device through S101 and S102. The antenna associated with the target tire refers to the antenna required to read data when determining the tire pressure sensor ID of the target tire, that is, the antenna used when calculating the tire pressure sensor ID of the target tire in the above S102 process.

[0148] For example, taking a 6×4 vehicle as an example, if the target tire is the first tire, the ID of the tire pressure sensor of the first tire can be determined based on the reading data of the first antenna alone, so the antenna associated with the target tire is the first antenna; if the target tire is the third tire, the ID of the tire pressure sensor of the third tire can be determined based on the reading data of the third antenna and the reading data of the fourth antenna, so the antennas associated with the target tire are the third antenna and the fourth antenna.

[0149] In this embodiment, if there is a target tire, the steps of controlling the antenna associated with the target tire to read the ID of the tire pressure sensor of the corresponding tire, and re-determining the ID of the tire pressure sensor of the target tire based on the data re-read by the antenna associated with the target tire are repeated until the ID of the tire pressure sensor of the target tire is determined, or the steps of controlling the antenna associated with the target tire to read the ID of the tire pressure sensor of the corresponding tire, and re-determining the ID of the tire pressure sensor of the target tire based on the data re-read by the antenna associated with the target tire are repeated for a number of times reaching a preset number of times. The preset number of times can be set according to actual needs, for example, it can be 3 times, 2 times, etc.

[0150] If the steps of repeatedly controlling the antenna associated with the target tire to read the ID of the tire pressure sensor of the corresponding tire and re-determining the ID of the tire pressure sensor of the target tire based on the data re-read by the antenna associated with the target tire reach a preset number of times and the ID of the tire pressure sensor of the target tire is still not determined, it is prompted that the ID learning of the tire pressure sensor has failed and the offline learning process is exited.

[0151] If there is a target tire, the IDs of the tire pressure sensors of other tires are stored, and after the ID of the tire pressure sensor of the target tire is determined, the IDs of the tire pressure sensors corresponding to each tire are written into the corresponding controller of the vehicle, or, after prompting that the ID learning of the tire pressure sensor has failed, the offline learning process is exited. The above-mentioned other tires are tires other than the target tire, that is, tires whose tire pressure sensor IDs have been determined.

[0152] In some embodiments, in the above S101, while controlling each antenna to read the ID of the corresponding tire pressure sensor, the offline learning method of the tire pressure monitoring system of the vehicle further includes:

[0153] The drum device where the vehicle is located is controlled to work at a preset speed for a preset time.

[0154] The off-line learning process of the vehicle's tire pressure monitoring system needs to be completed on the drum device. When the EOL device starts the off-line learning process, it controls the drum device where the vehicle is located to work at a preset speed to rotate the vehicle's wheels, and at the same time controls each antenna to read the ID of the corresponding tire pressure sensor, and controls the drum device to stop working after the drum device has worked for a preset time. Each antenna completes the tire pressure sensor ID reading process within the preset time.

[0155] The preset speed and the preset duration can be set according to actual needs. For example, the preset speed can be 5 km / h and the preset duration can be 30 seconds.

[0156] The offline learning method of the tire pressure monitoring system of a vehicle provided in the embodiment of the present application can be applied to any road vehicle and non-road vehicle equipped with a tire pressure monitoring system, for example, it can be applied to heavy vehicles equipped with a tire pressure monitoring system, and it can also be applied to passenger cars equipped with a tire pressure monitoring system, and so on.

[0157] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
