BACKGROUND

Technical Field

The present disclosure relates to a system and method for setting multiple tire sensor identification codes using a handheld device.

Description of Related Art

In order to improve driving safety, most of the existing vehicle tires are equipped with a tire sensor (e.g., TPMS sensor) that can be used to detect tire status, such as tire pressure, temperature, etc. The existing tire pressure sensor is installed inside a tire to detect the tire pressure, and then a tire pressure signal containing an identification code of the tire pressure sensor is transmitted to a tire pressure receiver, such as electronic control unit (ECU) of car, which is the car computer. The car computer can identify different tire pressure sensors, owing to each of the tire pressure sensors has a unique identification code itself. For example, assuming that four tire pressure sensors are installed on four wheels of the car, and the identification code of each of the tire pressure sensors is 1, 2, 3, 4, respectively. When the battery power of the four tire pressure sensors is exhausted, about to run out or the tire pressure sensors are damaged, it is necessary to replace the old ones with new tire pressure sensors, and the identification code of each of the new tire pressure sensors is 5, 6, 7, 8, respectively. However, the car computer cannot identify the new tire pressure sensors with identification codes 5, 6, 7, 8, thus the car computer cannot receive the tire pressure signals. Therefore, the car computer must enter a learning mode to learn the new identification codes, so that the car computer can receive the tire pressure signal from the tire pressure sensors with identification codes 5, 6, 7, and 8, and the new tire pressure sensors will be recognized by the car computer. However, it needs certain operation processes to enter the learning mode of the car computer, and it will take a lot of time. This is due to the vehicle owner may accidentally enter the learning mode by just pressing a button, which may cause safety problems of the car, therefore the car manufacturer commonly produces complicated operation processes of entering the learning mode of the car computer, so that the vehicle cannot enter the learning mode easily. Therefore, a method which uses a setting tool and without entering the learning mode of the car computer is developed. In this method, the identification codes 1, 2, 3, 4 are inputted into the setting tool firstly, after the setting tool obtains the identification codes 1, 2, 3, 4, the identification codes 1, 2, 3, 4 are transmitted to the four new tire pressure sensors by the setting tool, and the identification codes of the four new tire pressure sensors will be replaced by 1, 2, 3, 4. And then the new tire pressure sensors will transmit the tire pressure signal to the car computer with the identification codes 1, 2, 3, 4. However, in this method, the identification codes cannot be inputted at a time into the setting tool. For example, if a tire pressure sensor of the left front wheel is damaged (e.g. run out of the electric power), the old tire pressure sensor of the left front wheel should be removed firstly, and then selecting the left front wheel on the operation interface of the setting tool, and then using the keyboard on the operation interface of the setting tool to input the identification code as 1, and then transferring the identification code 1 from the setting tool to the new tire pressure sensor, and finally installing a new tire pressure sensor in a location of the left front wheel. The above processes must be operated four times due to a car has four tires. In another method, when the old tire pressure sensor of the left front wheel still has a little electric power, the setting tool transmits a wireless low-frequency signal to the old tire pressure sensor, this is a so-called trigger action. When the old tire pressure sensor is triggered, it will transmit back tire pressure signal with identification code 1 to the setting tool; at the time, this tire pressure signal is a high-frequency RF signal, and then the setting tool transmits the identification code 1 to the new tire pressure sensor. This kind of method requires four times operations as well. The reason that using the setting tool to select the tire location is to prevent confusion. The four old tire pressure sensors are commonly removed at a time, and then the four old tire pressure sensors are used one by one to transmit the identification code to the setting tool. The purpose of selecting the tire location on the setting tool is to record that the old tire pressure sensor in which location of the tire has transmitted identification code to the setting tool. When this identification code is transmitted to the new tire pressure sensor, the user can know that on which tire location the new tire pressure sensor should be installed. There is another method that using the setting tool with a cable, one end of the cable is plugged into the setting tool, the other end of the cable is plugged into an on-board diagnostic system (OBD), and then the identification codes of the four old tire pressure sensors and the installation location of each of the tire pressure sensors on the tires can be read from the car computer to the setting tool. However, it also takes time for the user to plug one end of the cable into the setting tool and the other end of the cable into the OBD. Furthermore, this method is not available if the cable is accidentally lost. Another issue may be occurred when the data stored in the car computer is incorrect or missing.

Please refer to FIG. 5, and FIGS. 1 and 2 are also referred herein, a method for setting multiple tire sensors identification codes of the present disclosure includes the following steps.

A database 110 is provided for storing multiple vehicle owner information, multiple tire sensor identification codes associated with the owner information and installation locations of multiple tire sensors 160 on the vehicle. It should be mentioned that a plurality of different vehicle owner information, tire sensor identification codes and/or installation locations are stored on the database. For example, the database stores the name of a vehicle owner A, his vehicle owner information (VIN, license plate number, vehicle owner name, vehicle owner phone number, vehicle owner address, vehicle owner Email, etc.), the tire sensor identification codes 1, 2, 3 and 4, and the installation locations of the four tire sensors 160 on the vehicle (left front, left rear, right front and right rear). The database 110 also stores the name of a vehicle owner B, his vehicle owner information and related tire sensor identification codes and/or installation locations. Therefore, the vehicle owner information of the vehicle owner A should be associated with the tire sensor identification codes 1, 2, 3, 4, and/or the installation locations of tire sensors 160 on the vehicle to distinguish from the vehicle owner information of the vehicle owner B and its related tire sensor identification codes and/or installation locations.

Therefore, when one of the vehicle owner information of the vehicle owner A is inputted into the handheld device 120, the tire identification codes 1, 2, 3, 4 and/or the installation locations associated with the vehicle owner information can be searched on the database 110, but the vehicle owner information of the vehicle owner B and its related tire identification codes and/or installation locations won't be searched.

A wire or wireless connection to the database 110 is established by the controller area network (CANBUS) module 120i of the handheld device 120 or a wireless communication chip, multiple tire sensor identification codes and/or installation locations of the tire sensors 160 are obtained from the database 110 to the handheld device 120. A vehicle owner information can be inputted into the handheld device 120. The lens module 120e can be used to obtain messages (e.g., license plate number) by scanning or taking pictures; the vehicle owner information such as vehicle owner name, vehicle owner phone number, VIN, etc., can be inputted through the display module 120f or the operation module 120k, and the vehicle owner information can be uploaded to the database 110. Therefore, the related tire sensor identification codes and/or the installation locations can be searched through the vehicle owner information stored in the database 110. For example, general vehicle will be equipped with four tire sensors 160, and the four tire sensors identification codes and/or installation locations associated with the vehicle will be searched and transmitted to the handheld device 120. The display module 120f or the operation module 120k can also be used to input the tire sensor identification codes and/or the installation locations.

The tire sensor identification codes are re-written, the low-frequency transceiver 120i or the first Bluetooth module of the handheld device 120 transmits old tire sensor identification codes and/or installation locations to the receiver module 164 or the second Bluetooth module of new tire sensors 160 to replace the original identification codes of the new tire sensor 160 (or the new tire sensors 160 originally did not have identification codes in the storage module 162 thereof), so that the new tire sensors 160 have identification codes and/or installation locations. In another example, the NFC module of the handheld device 120 can also be used to transmit a signal (including identification codes and/or installation locations) to the NFC circuit of the new tire sensors 160. In addition to the wireless connection, the new tire sensors 160 and the handheld device 120 can be connected physically. For example, the new tire sensor 160 can also be connected to the handheld device 120 through a cable, and the signal (including identification codes and/or installation locations) can be transmitted to the new tire sensor 160 through the cable. In order to ensure that the new tire sensor 160 receives the identification codes of the old tire sensor 160, the new tire sensor 160 will transmit back a signal including identification codes to the handheld device 120, and determine whether the identification codes obtained from the new tire sensor 160 are the same as the identification codes obtained from the database 110, if not, the handheld device 120 must obtain the old tire sensor identification codes from the database 110 again. If the same, indicating that the identification codes of the old tire sensors 160 are successfully written to the new tire sensors 160.

Therefore, when the old tire sensors 160 are failure, damaged, aged or ran out of electric power and should be replaced by new ones, the new tire sensors 160 can use the identification codes and installation locations of the old tire sensors 160, thus the car computer can directly identify the new tire sensors 160 with the old identification codes, there is no need to go through a complex code learning process to set the identification codes of the new tire sensors 160. Therefore, the efficiency of setting multiple tire sensor identification codes can be enhanced, the time required for setting the identification code can be shorten as well, thereby increasing overall efficiency and accuracy.

The establishment of the data such as the vehicle owner information, the identification codes and the installation locations in the database 110 can be achieved through the method shown in FIG. 6.

A vehicle owner information (including a vehicle identification number (VIN), a license plate number, a vehicle owner name, etc.) is inputted to the handheld device 120.

An identification code and an installation location of an old tire sensor 160 is inputted to the handheld device 120.

The handheld device 120 transmits the vehicle owner information, the identification code and/or the installation location to the database 110 for storage, and the vehicle owner information and its related identification code and/or installation location are associated in the database 110; or without using the database 110, the vehicle owner information and its related identification code and/or installation location are directly associated and then stored in the database 110. The above information is stored in the memory 120d or in the database 110. In another example, the vehicle owner information and its related identification code and/or installation location can also be associated and stored in the car computer or the tire pressure receiver connected to the car computer. Or the car computer and the tire pressure receiver are connected to a database through a network, then the vehicle owner information and its related identification code and/or installation location can also be associated and stored in the database.
