[0071] The above drawings illustrate specific embodiments of the present invention, which will be described in more detail below. These drawings and the accompanying description are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0072] Exemplary embodiments are described in detail herein, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present invention.

[0073] In this document, it should be understood that the terms involved are only used to facilitate understanding and do not represent any limitation on the meaning. In addition, the number of any element in the drawings is for illustration and not limitation, and any naming is only for distinction and does not have any limiting meaning.

[0074] The data involved in the present invention may be data authorized by the user or fully authorized by all parties, and the collection, dissemination, and use of the data shall comply with the requirements of relevant national laws and regulations.

[0075] For a vehicle, when a user replaces a tire, a tire sensor conflict may occur, resulting in the tire information received by the vehicle not reflecting the information of the tire actually installed on the vehicle. For example, a vehicle has four tires. When tire 1 in wheel position 2 is replaced on wheel position 1, and a new tire is replaced on wheel position 2, and a matching operation is performed on the tire sensor in wheel position 1 but not on the tire sensor in wheel position 2, the tire information received by the vehicle will only contain information about tire 1 in both wheel positions 1 and 2. As a result, the vehicle will not receive information about the newly installed tire in wheel position 2, and the tire in wheel position 2 may have blown out without the user noticing.

[0076] Figure 1 A schematic diagram of a tire sensor matching processing method provided by an embodiment of the present invention is shown in FIG. Figure 1 As shown, the method includes:

[0077] Step S101: Determine tire information of multiple tires in a vehicle, where the tire information includes tire sensor IDs and corresponding wheel positions.

[0078] When performing tire sensor matching, the tire information of multiple tires in the vehicle can be determined first. Specifically, the tire information of all tires in the vehicle can be obtained. For example, when the vehicle has four tires, the tire sensor IDs and corresponding wheel position information of the four tires are obtained.

[0079] Optionally, the acquired tire information may be tire information corresponding to each tire sensor in the current cycle.

[0080] Step S102: Determine conflicting tire sensor IDs based on tire information of the multiple tires.

[0081] When determining whether a vehicle has a tire sensor conflict, the obtained tire information of multiple tires can be compared. Optionally, when two tire sensor IDs are the same, it can be determined that the vehicle has a tire sensor conflict. When two tire sensor IDs are the same, the tire sensor ID is the tire sensor ID with the conflict.

[0082] For example, if the four tire sensor IDs in the vehicle are ID1, ID2, ID3, and ID3, ID3 is determined to be the conflicting tire sensor ID.

[0083] Step S103: Determine the wheel position of the conflicting tire sensor ID.

[0084] After the conflicting tire sensor ID is determined, the wheel position corresponding to the conflicting tire sensor ID can be extracted to obtain the wheel position of the conflicting tire sensor ID, so that the staff can perform subsequent matching operations based on the determined wheel position.

[0085] The present invention provides a tire sensor matching processing method, which includes: determining tire information of multiple tires in a vehicle, the tire information including the tire sensor ID and the corresponding wheel position, determining the conflicting tire sensor ID based on the tire information of the multiple tires, and determining the wheel position of the conflicting tire sensor ID. By determining the conflicting tire sensor ID and wheel position in the vehicle based on the tire information of the multiple tires in the vehicle, a staff member can perform a matching operation to ensure that the vehicle does not have a tire sensor conflict problem, and can accurately obtain the tire information of each tire, so that not only abnormal tires can be discovered in a timely manner, but also the wheel position of the abnormal tire can be discovered.

[0086] For vehicles with multiple carriages, each carriage corresponds to multiple tires, and each tire is equipped with one or two tire sensors. The tire sensors can collect information such as the voltage or temperature of the tire and report it to the vehicle, so that the vehicle can display the obtained voltage or temperature information to the user, so that the user can determine the information of the tire during the operation of the vehicle. When the tire voltage or temperature information is abnormal, the corresponding tire is checked to prevent the vehicle from having a tire blowout during operation.

[0087] The following scenarios may occur: when the tire sensor is bound to the tire, if a tire in one car is moved to another, the tire sensor must also be moved to the other car. Alternatively, when the tire sensor is not bound to the tire, a tire sensor in one car may be moved to another car. In these scenarios, the tire sensors need to be re-paired. If the operator forgets to re-pair, the vehicle will still receive information sent by the tire sensor before the replacement.

[0088] Figure 2 A schematic diagram of a scenario in which a vehicle has multiple compartments is provided in an embodiment of the present invention, such as Figure 2As shown, a vehicle has three cars. First, tire sensor 1 in car 2 is replaced in car 1, and then tire sensor 2 is replaced in car 2. If only the tire sensor in car 1 is re-matched without re-matching tire sensor 2 in car 2, the information corresponding to car 2 obtained by the vehicle will still be the information sent by tire sensor 1, and the information corresponding to car 1 obtained by the vehicle will also be the information sent by tire sensor 1. Therefore, a tire sensor conflict will occur. In this scenario, tire sensor 2 may have a blowout, but because the vehicle receives data from tire sensor 2, the displayed data will appear normal.

[0089] Based on the above problems, this application determines the tire sensor ID and the corresponding wheel position corresponding to each car, compares the tire sensor IDs of each car to determine the conflicting tire sensor ID, and continues to determine the actual installation wheel position of the conflicting tire sensor ID. For example, if both car 1 and car 2 correspond to the information sent by tire sensor ID1, it can be determined that there is a tire sensor conflict in the vehicle, and then determine whether tire sensor ID1 is actually installed in car 1 or car 2, so that users can solve the problem of tire sensor conflict in time, thereby accurately obtaining the data reported by the tire sensors actually installed in each car.

[0090] In view of the above scenario, an embodiment of the present invention provides a tire sensor matching processing method, the method comprising:

[0091] Step 1: Determine tire information of each compartment in the vehicle, where the tire information of each compartment includes multiple tire sensor IDs of the compartment and corresponding wheel positions.

[0092] A vehicle contains multiple carriages. To determine whether there is a tire sensor conflict, the tire information for each carriage, also known as tire sensor matching status information, can be obtained. Specifically, this information includes the tire sensor ID and wheel position corresponding to each carriage. Each tire sensor ID is unique, as they differ from one another.

[0093] Optionally, in order to improve the accuracy of determining whether there is a tire sensor conflict in the current vehicle, the tire information of each compartment in the vehicle determined here is the most recent tire information of each tire sensor in the compartment.

[0094] For example, when there are three carriages, each carriage corresponds to four tires, and each tire is provided with a tire sensor, the tire information obtained by the vehicle may be that the tire sensor IDs corresponding to carriage 1 are ID1, ID2, ID3 and ID5 respectively; the tire sensor IDs corresponding to carriage 2 are ID5, ID6, ID7, ID8 respectively; the tire sensor IDs corresponding to carriage 3 are ID9, ID10, ID11 and ID12 respectively. At the same time, the tire information also includes the wheel position corresponding to each tire sensor ID.

[0095] This application can be applied to a vehicle with a fixed route, using rubber wheels as the vehicle running parts, and consisting of multiple carriages connected by physical means. Step 2: Determine the conflicting tire sensor IDs based on the tire information of each carriage.

[0096] After determining the tire information corresponding to each vehicle compartment, the tire sensor IDs corresponding to each vehicle compartment can be compared to determine whether there is a tire sensor conflict in the vehicle. A tire sensor conflict means that the same tire sensor ID corresponds to two or more vehicles.

[0097] A scenario in which a tire sensor conflict occurs is when tire sensor 1 in car 2 is replaced with car 1, and tire sensor 2 is replaced with car 2. If only the tire sensor in car 1 is rematched and the tire sensor in car 2 is not rematched, then the tire information received by the vehicle in the end includes: the tire sensor corresponding to car 2 includes tire sensor 1 but not tire sensor 2, while the tire sensor corresponding to car 1 also includes tire sensor 1, so that the information of tire sensor 1 corresponds to both cars.

[0098] Optionally, if the tire information of at least two carriages contains the same tire sensor ID, then the tire sensor ID is considered a conflicting tire sensor ID. Specifically, the tire sensor IDs corresponding to any two carriages are compared. If the same tire sensor ID corresponds to at least two carriages, then the tire sensor ID is determined to be a conflicting tire sensor ID.

[0099] As in the above example, the tire sensor IDs corresponding to carriage 1 are ID1, ID2, ID3, and ID5; the tire sensor IDs corresponding to carriage 2 are ID5, ID6, ID7, and ID8. Therefore, both carriages correspond to tire sensor ID5, and tire sensor ID5 is the conflicting tire sensor ID.

[0100] Step S3: Determine the wheel position of the conflicting tire sensor ID.

[0101] The tire information also includes the wheel positions corresponding to each tire sensor ID. After the conflicting tire sensor ID is determined, the actual installation wheel position can be determined from the wheel positions corresponding to the tire sensor ID.

[0102] As in the above example, after determining that tire sensor ID5 is a conflicting tire sensor ID, it is further possible to determine whether tire sensor ID5 is actually located in car 1 or car 2 .

[0103] For scenarios where a vehicle has multiple carriages, by first determining the conflicting tire sensor ID and then determining the wheel position of the conflicting tire sensor ID, the staff can determine whether the vehicle has a tire sensor conflict after replacing the tires of two carriages without performing a matching operation on a certain carriage. After determining the wheel position of the conflicting tire sensor ID, the staff can continue to perform the matching operation to enable the vehicle to accurately obtain the tire information of each carriage.

[0104] Optionally, determining conflicting tire sensor IDs based on the tire information of each vehicle compartment includes:

[0105] If it is detected that there is at least one carriage to be checked among the carriages, the tire information of at least one of the carriages to be checked is compared with the tire information of other carriages in the vehicle except the carriage to be checked. When the tire information of at least two carriages contains the same tire sensor ID, the same tire sensor ID is determined to be a conflicting tire sensor ID; the carriage to be checked is the carriage whose tire information has changed.

[0106] When determining whether a vehicle has a tire sensor conflict, it may also be determined first whether there is a carriage to be verified among the carriages, where the carriage to be verified refers to a carriage whose tire information has changed.

[0107] For example, if the corresponding tire sensor IDs of a certain carriage were ID1, ID2, ID3, and ID4 before, and later became ID1, ID2, ID3, and ID5, it means that the tire sensors of the carriage have changed and a matching operation has been performed, that is, the matching status of the tire sensors of the carriage has changed.

[0108] Typically, when a tire sensor in one vehicle is swapped to another, if a pairing operation has been performed on one vehicle, a tire sensor conflict may occur because the pairing operation has not been performed on the other vehicle. Therefore, it is possible to first determine whether there is a vehicle to be verified. If so, the tire information of the vehicle to be verified is then compared with the tire information of the other vehicles in the vehicle to determine the conflicting tire sensor ID.

[0109] Optionally, the number of carriages to be checked determined at a certain moment may be multiple, and then for each carriage to be checked, an operation of comparing the tire information of the carriage to be checked with the tire information of other carriages in the vehicle may be performed.

[0110] Furthermore, if all vehicles are not the ones being verified, even if the tire sensors have been replaced, there will be no tire sensor conflicts because the user has not yet performed the matching operation on the two replaced vehicles. In other words, a conflicting tire sensor ID will only occur if the tire information of at least one vehicle has changed.

[0111] Optionally, after determining the conflicting tire sensor IDs, tire conflict alarm information may be sent, where the tire conflict alarm information includes the conflicting tire sensor IDs and corresponding wheel positions.

[0112] By comparing the tire information of a carriage to be verified with the tire information of other carriages when there is one, it is not necessary to compare the information to be verified of all carriages in pairs, which can reduce the amount of calculation and avoid invalid detection.

[0113] Optionally, each compartment is provided with a receiving module, and the step of determining tire information of each compartment in the vehicle includes:

[0114] Receive the tire information of each carriage sent by a receiving module set in the carriage; wherein the receiving module is used to receive the initial tire information sent by the matched tire sensor, and generate the tire information of the carriage based on the tire sensor ID in the initial tire information and the stored wheel position corresponding to the tire sensor ID.

[0115] A receiving module can also be set up in each compartment of the vehicle. Each receiving module can receive the initial tire information sent by the matched tire sensor in the compartment. At the same time, the wheel position corresponding to the matched tire sensor ID is stored in the receiving module, so that the tire sensor ID and wheel position can be combined into tire information.

[0116] Each vehicle compartment may also be provided with an onboard data processing device. After the receiving module generates tire information, it may send the tire information to the corresponding onboard data processing device. The onboard data processing device may convert the received tire information into data in a vehicle communication message format and send the converted tire information to the vehicle. Specifically, the onboard data processing device may be a central processing unit in the vehicle. The execution subject of this application may be the central processing unit.

[0117] By setting up a receiving module in each car, the tire information of the matched tire sensor in each car can be received and sent to the central processor, so that the vehicle can accurately obtain the tire information of the matched tire sensors in each car.

[0118] Optionally, the tire information of each carriage is the tire information of each carriage in the current cycle, and the method further includes:

[0119] Get the tire information corresponding to each carriage in the previous cycle;

[0120] For each carriage, if there is at least one wheel position in the carriage where the tire sensor ID of the current cycle is inconsistent with the tire sensor ID of the same wheel position in the previous cycle, the carriage is determined as the carriage to be verified.

[0121] When determining whether a carriage is a carriage to be verified, the tire information of the carriage in the current cycle may be compared with the tire information of the carriage in the previous cycle to determine whether the tire information of the carriage has changed.

[0122] The tire information includes the tire sensor ID corresponding to the vehicle compartment, and also includes the wheel position information corresponding to each tire sensor ID. For example, tire sensor ID1 corresponds to wheel position 1 of vehicle compartment 1.

[0123] For any carriage, the tire sensor ID of the current cycle corresponding to the same wheel position is compared with the tire sensor ID of the previous cycle of the wheel position. If they are inconsistent, it is determined that the tire information of the carriage has changed.

[0124] By comparing the tire sensor ID of the current cycle corresponding to the same wheel position with the tire sensor ID of the previous cycle of the wheel position, the accuracy of determining whether the carriage is the carriage to be verified can be improved.

[0125] A specific embodiment is given below to illustrate the detailed process of determining whether a vehicle has tire sensor conflict.

[0126] Figure 3 A flowchart of a method for determining whether a tire sensor conflict exists in a vehicle is provided in an embodiment of the present invention. Figure 3As shown, in step S301, the central processor collects the most recent tire information for a particular car, i.e., the matching status information of the tire sensors. It then retrieves the stored tire information for that car from previous times, i.e., the historical matching records, and performs a one-to-one verification. Step S302: The tire sensor ID in the most recent tire information for a particular wheel position is compared with the tire sensor ID for the same wheel position from previous times. Step S303: If any inconsistency is detected between the tire sensor IDs for a particular wheel position, the most recent tire sensor IDs for each wheel position in that car are cached and the matching time information is recorded. Step S304: The tire sensor matching status information for all other cars in the train is retrieved and verified against each tire sensor ID of the car to be verified, without wheel position restrictions. Step S305: Whether there is a tire sensor ID conflict between two or more wheel positions is determined. If so, step S306 is executed: the conflicting tire sensor ID and the wheel position in which it resides are marked. Step S307: A tire sensor ID conflict alarm is issued for the corresponding wheel position.

[0127] Optionally, the tire information further includes tire status information corresponding to the tire sensor ID; and determining the actual installation wheel position of the conflicting tire sensor ID includes:

[0128] For each conflicting wheel position, determining an average update time of the tire status information corresponding to the conflicting wheel position; the average update time is related to a target time interval; the target time interval represents the time interval for a corresponding receiving module to receive data from a corresponding tire sensor; wherein the conflicting wheel position is the wheel position corresponding to each of the conflicting tire sensor IDs;

[0129] The actual installation wheel position corresponding to the tire sensor ID is determined according to the average update time of each conflicting wheel position.

[0130] Optionally, the receiving module can be set on the chassis of the vehicle. When the tire sensor of one vehicle is replaced to another vehicle, a matching operation can be performed manually. The matching operation refers to inputting the ID information of the replaced tire sensor into the receiving module so that the receiving module will subsequently receive the data broadcast by the replaced tire sensor, and no longer receive the data broadcast by the tire sensor before the replacement.

[0131] When a tire sensor is replaced from car 2 to car 1, if the receiving module of car 1 is matched but the receiving module of car 2 is not matched, the receiving modules of the two cars will receive the data sent by the tire sensor. However, the distance between the tire sensor and the receiving module in car 1 is closer, and the distance between the tire sensor and the receiving module in car 2 is farther. Therefore, the actual installation wheel position of the tire sensor can be determined based on the data received by the two receiving modules.

[0132] Tire information can also include tire status information, such as temperature and pressure. To determine the actual wheel location for a tire sensor ID, one approach is to determine the average update time of the tire status information corresponding to each conflicting wheel location. This average update time refers to the average time interval between receiving data broadcast by the tire sensor by the receiving module.

[0133] For example, when the tire sensor's transmission cycle is 30 seconds, meaning data is broadcast every 30 seconds, if the time intervals for acquiring tire status information corresponding to the conflicting wheel position of car 1 are 30 seconds, 30 seconds, and 30 seconds, respectively, then the average update time is 30 seconds. If the time intervals for acquiring tire status information corresponding to the conflicting wheel position of car 2 are 30 seconds, 60 seconds, and 60 seconds, respectively, then the average update time is 50 seconds. The average update time corresponding to the conflicting wheel position can be determined based on the same time period.

[0134] The actual wheel position corresponding to the tire sensor ID can be determined based on the average update time corresponding to each conflicting wheel position. This is because the tire sensor transmits data to the central processor via a receiving module. Receivers closer to the actual installation location of the tire sensor receive more accurate tire information, making it less likely to miss tire information. Receivers farther from the actual installation location are more likely to miss tire information. Therefore, the actual installation location of the tire sensor ID can be determined based on the average update time of the tire status information corresponding to the conflicting wheel position.

[0135] For conflicting wheel positions, the validity of the tire information for each conflicting wheel position can be determined first, and then the actual installation location of the tire sensor can be determined from each conflicting wheel position for which the tire information is valid. Optionally, if the tire information contains data such as pressure and temperature, it indicates that the tire information for the conflicting wheel position is valid.

[0136] Optionally, determining the wheel position corresponding to the tire sensor ID according to the average update time of each conflicting wheel position includes:

[0137] The conflicting wheel position corresponding to the shortest average update time is determined to be the actual installation wheel position corresponding to the tire sensor ID.

[0138] After determining the average update time corresponding to each conflicting wheel position, the conflicting wheel position corresponding to the shortest average update time can be determined as the actual installation wheel position of the tire sensor ID. The shortest average update time means that the receiving module of the carriage misses the least data sent by the tire sensor, that is, the receiving module is the receiving module closest to the actual installation position of the tire sensor.

[0139] By determining the conflicting wheel position corresponding to the shortest average update time as the actual installation wheel position of the tire sensor ID, the actual installation position of the conflicting tire sensor ID can be determined simply and accurately.

[0140] Optionally, determining that the conflicting wheel position corresponding to the shortest average update time is the actual installation wheel position corresponding to the tire sensor ID includes:

[0141] When the difference between the shortest average update time and any other average update time exceeds a preset value, the conflicting wheel position corresponding to the shortest average update time is determined as the actual installation wheel position corresponding to the tire sensor ID.

[0142] When the conflicting wheel position corresponding to the shortest average update time is determined as the actual installation wheel position of the tire sensor ID, it can also be determined whether the difference between the shortest average update time and any other average update time exceeds a preset value. If the difference exceeds the preset value, the actual installation wheel position corresponding to the tire sensor ID can be determined. Optionally, the preset value here can be the transmission period of the tire sensor.

[0143] Figure 4 A schematic diagram of a process for determining the actual installation position of a tire sensor provided by an embodiment of the present invention is shown in FIG. Figure 4 As shown, this example illustrates the situation where there are two conflicting wheel positions. Step S401 determines whether a tire sensor ID conflict exists between two carriages. Step S402 determines whether the tire sensor status information for the conflicting wheel positions is simultaneously valid. If both are valid, step S403 is executed to determine the average update time of the data corresponding to the two conflicting wheel positions. Step S404 compares the average update times of the two conflicting wheel positions, and the wheel position with the shorter average update time is determined as the actual installation position of the tire sensor.

[0144] By determining the actual installation position of the tire sensor ID when the difference between other average update times and the shortest average update time is relatively obvious, the accuracy of the determined actual installation position is improved.

[0145] Optionally, determining the wheel position of the conflicting tire sensor ID includes:

[0146] For each conflicting wheel position, a data reception rate is determined based on tire information received from a receiving module corresponding to the conflicting wheel position; the tire sensor sends the same tire information multiple times; wherein the conflicting wheel position is the wheel position corresponding to each of the conflicting tire sensor IDs;

[0147] The conflicting wheel position corresponding to the maximum data receiving rate is determined as the actual installation wheel position corresponding to the tire sensor ID.

[0148] When determining the actual wheel position for a tire sensor ID, the data reception rate corresponding to the conflicting wheel position can also be used. When broadcasting tire information, the tire sensor sends the same tire information multiple times to reduce packet loss during data transmission. Tire information is sent in data packets, which contain multiple data frames.

[0149] A receiving module located closer to the actual tire sensor installation location will acquire more accurate tire information from that sensor and be less likely to experience packet loss (i.e., failure to receive a data packet or a portion of a data packet). Conversely, a receiving module located farther from the actual tire sensor installation location will be more likely to experience packet loss. Therefore, the data reception rate corresponding to each conflicting wheel position can be calculated. The data reception rate can be calculated as the ratio of the data frames corresponding to that tire sensor received by the CPU to the total data frames transmitted by the tire sensor within a preset time period.

[0150] After the data receiving rate is determined, the conflicting wheel position with the highest data receiving rate may be determined as the actual installation wheel position of the tire sensor ID.

[0151] By calculating the data reception rate corresponding to each conflicting wheel position, the actual installation position of the tire sensor ID can be accurately determined.

[0152] Optionally, the method further includes:

[0153] For each conflicting wheel position, determine the most recent matching time of the car corresponding to the conflicting wheel position; the most recent matching time of the car is the time when the car is determined to meet the preset condition; the preset condition is: the tire sensor ID of at least one wheel position of the car in the current cycle is inconsistent with the tire sensor ID of the same wheel position in the previous cycle;

[0154] When the average update time of the tire status information corresponding to the conflicting wheel position is the longest and the corresponding car is not the target car, the conflicting wheel position is determined as an unmatched wheel position; the target car is the car with the latest matching time among the cars corresponding to the conflicting wheel positions.

[0155] For a car, when it is determined that the car is a car to be verified, that is, when it is determined that the tire sensor ID of at least one wheel position in the car in the current cycle is inconsistent with the tire sensor ID of the same wheel position in the previous cycle, the time when the car is determined to be a car to be verified can be determined as the matching time of the car. Here, the most recent matching time of each car can be used.

[0156] After determining the average update time of the tire rotation information corresponding to each conflicting wheel position, if the average update time of a certain conflicting wheel position is longer and the most recent matching time of the carriage corresponding to the conflicting wheel position is not the latest, then the conflicting wheel position can also be determined as an unfinished matching wheel position.

[0157] The above method can accurately determine the wheel position that has not been matched among the conflicting wheel positions based on the two pieces of information.

[0158] Optionally, the method further includes:

[0159] When there is a tire sensor offline fault in one of the conflicting wheel positions and the tire sensor cannot be restored, the conflicting wheel position is determined to be an incomplete matching wheel position.

[0160] When a tire sensor goes offline at a conflicting wheel position and cannot be recovered, it may be that the tire sensor was relocated without being matched. Specifically, when tire sensor 1 in car 5 is replaced with car 1 without matching the newly installed tire sensor in car 5, the receiving module in car 5 will still receive the tire information previously broadcast by tire sensor 1. However, tire sensor 1 is actually installed in car 1, which is too far away from car 5. Therefore, the receiving module in car 5 may not receive the tire information broadcast by tire sensor 1, resulting in the tire sensor of the corresponding wheel position in car 5 going offline.

[0161] When, among two or more conflicting wheel positions corresponding to a tire sensor ID, only one tire sensor of the conflicting wheel position has an offline fault, it means that the conflicting wheel position is an incomplete matching wheel position.

[0162] Optionally, the method further includes:

[0163] When at least two conflicting wheel positions have tire sensor offline faults and cannot be restored, it can be determined that there is a tire sensor failure.

[0164] By analyzing the above-mentioned special situations of conflicting wheel positions, it can be directly determined that there is a fault in the tire sensor or that the wheel position matching is not completed.

[0165] Optionally, the method further includes:

[0166] The target wheel position is determined as an uncompleted matching wheel position; the target wheel position is a wheel position among the conflicting wheel positions excluding the actually installed wheel position.

[0167] If there are multiple conflicting wheel positions for a tire sensor, after determining the actual installation position of the tire sensor, wheel positions other than the actual installation position can be determined as incomplete matching wheel positions. For example, if there are three conflicting wheel positions for the tire sensor ID: wheel position 1 of car 1, wheel position 2 of car 2, and wheel position 3 of car 3, after wheel position 1 of car 1 is determined as the actual installation position of the tire sensor, wheel positions 2 of car 2 and wheel position 3 of car 3 are incomplete matching wheel positions.

[0168] Directly determining the conflicting wheel positions other than the actually installed wheel positions as the incomplete matching wheel positions has the advantages of simplicity and high accuracy.

[0169] Optionally, the vehicle includes an onboard gateway, wherein the onboard gateway stores tire information corresponding to each vehicle compartment in an earlier period; the method further includes:

[0170] After determining tire information of each compartment in the vehicle in the current cycle, the tire information is sent to the vehicle gateway so that the vehicle gateway stores the tire information of each cycle;

[0171] Accordingly, the tire information corresponding to each carriage in the previous cycle is obtained, including:

[0172] The tire information corresponding to each carriage in the previous cycle is obtained from the vehicle-mounted gateway.

[0173] In a vehicle with multiple carriages, an onboard gateway may be provided. The onboard gateway includes a storage unit that can be used to store tire information corresponding to each carriage in each cycle. Specifically, each time the tire information for each carriage in the vehicle is determined for the current cycle, the tire information for each carriage in the current cycle is sent to the onboard gateway. The onboard gateway can then store the tire information for each cycle. When determining whether the tire information for a carriage has changed, the onboard gateway can retrieve the tire information for that carriage from the previous cycle.

[0174] By setting up an on-board gateway, it is convenient to store the tire information of each carriage in each cycle, so as to facilitate determining whether the tire information of each carriage has changed.

[0175] Optionally, the vehicle is provided with a vehicle-to-ground wireless module, and the method further comprises:

[0176] An alarm message is sent through the vehicle-ground wireless module; the alarm message includes the actual installed wheel position and the uncompleted matching wheel position.

[0177] A vehicle-to-ground wireless module can also be set up in the vehicle. After the actual installation location of the conflicting tire sensor ID is determined, an alarm message can be generated and sent through the vehicle-to-ground wireless module so that remote staff can perform matching operations on the vehicle based on the alarm information.

[0178] The generated alarm information may include the tire sensor ID, actual installation location, and incomplete wheel matching, so that the staff knows exactly which wheel positions need to be matched.

[0179] By setting up a vehicle-ground wireless module, the alarm information can be sent to the remote end, which helps the staff to perform matching operations in time.
