The following describes technical solutions of this specification with reference to the accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of this specification. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of this specification without creative efforts shall fall within the protection scope of this specification.
This embodiment discloses an identification configuration method, which may be applied to a scenario in which a tire pressure sensor of a vehicle needs to be replaced. The method may be performed by a TPMS dedicated tool or another terminal. The TPMS dedicated tool may be, for example, a handheld tire pressure sensor diagnostic device or a tire pressure sensor programming device; and the another terminal may include a smartphone or the like. As shown in
S10: Read identification information of an original tire pressure sensor stored in a tire pressure receiver.
In this embodiment, the identification information may be an identification code of the original tire pressure sensor and/or position information of a wheel in which the original tire pressure sensor is located.
Specifically, the tire pressure receiver may be provided internally or externally to a vehicle. The tire pressure receiver may be wirelessly connected to a tire pressure sensor and the tire pressure receiver may receive tire pressure information sent by the tire pressure sensor. The tire pressure receiver may store identification information of the tire pressure sensor, that is, the tire pressure receiver stores an identification code of the tire pressure sensor and position information of a wheel in which the tire pressure sensor is located. It may be understood that, the tire pressure receiver stores identification codes and corresponding position information thereof. When receiving a piece of tire pressure information, the tire pressure receiver may determine corresponding position information according to the identification code in the tire pressure information, so that a wheel corresponding to the tire pressure information may be learned, thereby implementing matching between the tire pressure receiver and the tire pressure sensor. If the tire pressure receiver cannot identify the identification code in the tire pressure information sent by the tire pressure sensor, the tire pressure receiver cannot learn the wheel corresponding to the tire pressure information, so that the tire pressure receiver cannot be matched with the tire pressure sensor. Therefore, a tire state cannot be monitored.
For example, the tire pressure receiver receives the tire pressure information sent by the tire pressure sensor. According to the identification code in the tire pressure information, the stored identification codes and the corresponding position information thereof, it may be determined that the wheel corresponding to the tire pressure information is the left front wheel of the vehicle, so that the tire pressure receiver may monitor a pressure or temperature state of the left front wheel of the vehicle according to the tire pressure information.
Herein, the position information of the wheel in which the tire pressure sensor is located may be understood as a position of the wheel relative to the vehicle. For example, the position information of the wheel in which the tire pressure sensor is located may be a left front wheel, a right front wheel, a left rear wheel, a right rear wheel, a spare tire or the like.
Therefore, when a tire pressure sensor needs to be replaced, the tire pressure sensor after the replacement needs to be matched with the tire pressure receiver in time.
In this embodiment of the present application, when a tire pressure sensor on a wheel of a vehicle needs to be replaced, the terminal may first read identification information of an original tire pressure sensor stored in the tire pressure receiver.
For example, the terminal may be connected to the tire pressure receiver and read the identification information of the original tire pressure sensor stored in the tire pressure receiver. The terminal and the tire pressure receiver may be in a wired or wireless connection, which is not limited herein. Herein, the terminal may read one or all of the identification code of the original tire pressure sensor and the position information of the wheel in which the original tire pressure sensor is located that are stored in the tire pressure receiver, which is not limited herein.
S20: Send the identification information to a new tire pressure sensor.
In a specific embodiment, the new tire pressure sensor is a programmable tire pressure sensor. Specifically, the new tire pressure sensor may be a blank universal tire pressure sensor, where the universal tire pressure sensor is a tire pressure sensor into which program files may be burned. For example, the new tire pressure sensor may be programmed according to the identification information of the original tire pressure sensor. One or more pieces of identification information such as the identification code of the original tire pressure sensor and the position information of the wheel are carried in the program files and sent to the new tire pressure sensor, thereby burning the identification information into the universal tire pressure sensor.
Specifically, the terminal may be wirelessly connected to the new tire pressure sensor. After a connection is established, the terminal may carry the identification information of the original tire pressure sensor in the program files and send the identification information to the new tire pressure sensor, so that the new tire pressure sensor may store the identification information carried in the program files according to the received program files. Therefore, the terminal burns the identification information into the new tire pressure sensor by using the program files.
In this embodiment, after the identification information of the original tire pressure sensor is obtained, a single new tire pressure sensor may be selected to be programmed and the identification information of the original tire pressure sensor is burned into the new tire pressure sensor. Alternatively, a plurality of new tire pressure sensors may be programmed sequentially according to an actual situation.
For example, the terminal may install the new tire pressure sensor to the corresponding wheel after the identification information is burned into the new tire pressure sensor. Alternatively, the tire pressure receiver may burn the identification information into the new tire pressure sensor after the new tire pressure sensor is installed to the wheel.
After a communications connection is established to the tire pressure receiver in the automobile, the identification information of the original tire pressure sensor stored in the tire pressure receiver is read, where the identification information may be the identification code of the original tire pressure sensor and/or the position information of the wheel in which the original tire pressure sensor is located. The identification information is sent to the new tire pressure sensor, so that the new tire pressure sensor carries the identification information when sending tire pressure information to the tire pressure receiver. The identification code of the original tire pressure sensor and/or the position information of the wheel in which the original tire pressure sensor is located may be burned into the new tire pressure sensor. The identification information in the new tire pressure sensor is completely the same as that in the original tire pressure sensor, so that the new tire pressure sensor can be quickly matched with the tire pressure receiver.
In an optional embodiment, the step of reading the identification information of the original tire pressure sensor stored in the automobile is shown in
S11: Send a reading instruction to the tire pressure sensor.
In a specific embodiment, the reading instruction may be sent to the automobile in a wireless communications manner such as Bluetooth or a local area network. Alternatively, the reading instruction may be sent to the automobile in a wired manner. In this embodiment, after a connection is established to the tire pressure receiver, one or more reading instructions may be sent to an OBD according to a quantity of the tire pressure sensors to be replaced. In this embodiment, the reading instruction may specify to read identification information of an original tire pressure sensor in a particular wheel of an automobile. For example, if the left front wheel of the vehicle needs to be replaced, a reading instruction that specifies to read identification information of an original tire pressure sensor of the left front wheel may be sent. Alternatively, an instruction for reading all or some of the original tire pressure sensors may be sent, which is not limited herein.
S12: Receive identification information sent for the reading instruction by the tire pressure receiver.
In a specific embodiment, after receiving the reading instruction, the tire pressure receiver feeds back corresponding identification information according to the reading instruction. A terminal, for example, a TMPS dedicated tool, receives the identification information.
In a specific embodiment, to prevent the information receiving from being interfered, after receiving the identification information sent for the reading instruction by the tire pressure receiver, the terminal needs to determine whether the identification information fed back by the tire pressure receiver is a positive response. In this embodiment, the positive response may be response information including an identification code of an original tire pressure sensor and/or check information.
In a specific embodiment, the terminal may receive a plurality of types of information and the received information needs to be verified. Specifically, whether the received information includes the identification code of the original tire pressure sensor may be verified. Alternatively, whether the received information includes a byte or a byte having a particular length may be verified. If the verification succeeds, the identification information is a positive response of the tire pressure receiver.
When the received information is a positive response, information such as the identification code of the original tire pressure sensor is parsed from the identification information.
Before the identification information is sent to the new tire pressure sensor, a communications connection needs to be established to the new tire pressure sensor. In an optional embodiment, as shown in
In a specific embodiment, a terminal may broadcast a low-frequency signal within a range, and the frequency of the signal may be 125 kHz. In this embodiment, the broadcast signal sent in a broadcast manner carries the connection request.
S22: Receive a connection response sent for the connection request by at least one new tire pressure sensor.
In a specific embodiment, after receives a broadcast signal, the new tire pressure sensor detects whether a connection request exists in the broadcast signal, and when the connection request exists, determines according to a preset protocol or instruction whether the connection request is valid. When the preset protocol or instruction exists, the new tire pressure sensor may determine that the connection request is valid and returns a connection response signal corresponding to the connection request. By verifying the validity of the broadcast signal, interference from another signal may be filtered out, thereby ensuring an accurate connection to the new tire pressure sensor.
The tire pressure receiver may determine a quantity of the new tire pressure sensors to be connected according to a quantity of received connection responses.
S23: Establish a connection to the at least one new tire pressure sensor respectively.
After the connection response returned by the new tire pressure sensor is received, a physical address of the new tire pressure sensor may be obtained according to the connection response. Each tire pressure sensor has a unique physical address. That is, the connection may be established based on the physical address of the new tire pressure sensor.
In the foregoing manner, connections to a plurality of new tire pressure sensors can be implemented, so that matching efficiency can be further improved.
After the connection is established to the new tire pressure sensor, the identification information may be sent to the new tire pressure sensor. In an optional embodiment, sending the identification information to the new tire pressure sensor may include the following steps:
S24: Determine identification information corresponding to each of the at least one new tire pressure sensor.
In a specific embodiment, after the quantity of the new tire pressure sensors is determined in the foregoing manner, the identification information may be associated with the physical address of the new tire pressure sensor. Specifically, to simplify operation steps of an operator and reduce workload of the operator, the identification information may be randomly associated with a physical address of a selected new tire pressure sensor. In another optional implementation, to avoid confusion after the association, the association may also be performed in a preset sequence.
S25: Send sequentially each piece of the identification information to the corresponding new tire pressure sensor, so that the new tire pressure sensor records the corresponding identification information.
In a specific embodiment, after the identification information corresponding to the new tire pressure sensor is determined, the identification information may be sent to the corresponding new tire pressure sensor according to a correspondence and based on the physical address of the new tire pressure sensor. Specifically, after receiving the identification information, the new tire pressure sensor may record the identification information and update the identification information to its own program, so that the new tire pressure sensor carries the identification information when sending tire pressure information.
In another embodiment, an identification configuration method of the tire pressure sensor may further activate the new tire pressure sensor. Activation of the new tire pressure sensor means determining an installation position of the new tire pressure sensor. The method may be applied to a scenario in which the tire pressure sensor has not been installed. As shown in
S100: Read identification information of an original tire pressure sensor stored in a tire pressure receiver. For details, reference may be made to descriptions of reading identification information in step S10 in the foregoing embodiment.
S200: Send the identification information to a new tire pressure sensor. For details, reference may be made to descriptions of sending the identification information to a new tire pressure sensor in step S20 in the foregoing embodiment.
S300: Receive the identification information corresponding to the new tire pressure sensor. In a specific embodiment, the identification information in the new tire pressure sensor may be received in a wireless manner such as Bluetooth.
S400: Determine position information of the new tire pressure sensor according to the identification information. In a specific embodiment, because the identification information of the new tire pressure sensor is the identification information of the original tire pressure sensor, the identification information includes an identification code of the original tire pressure sensor and/or position information of the original tire pressure sensor. By parsing the identification information, the position information of the original tire pressure sensor may be parsed out from the identification information, so that a wheel in which the new tire pressure sensor is located may be learned. For example, if identification information of a new tire pressure sensor is identification information of an original tire pressure sensor of the left front wheel, it can be learned after parsing that the new tire pressure sensor needs to be installed to the left front wheel.
S500: Output prompt information including the position information. In a specific embodiment, after the position information of a wheel in which the new tire pressure sensor is located is determined, prompt information corresponding to the position information may be output. For example, words of a specific position may be displayed on a display screen, or a position of the wheel in which the new tire pressure sensor is located may be broadcast through voice broadcasting. Therefore, it may be convenient for an operator to install the new tire pressure sensor according to the prompted position information. In this way, an installation error is avoided and installation efficiency is improved.
