Hereinafter, the present invention will be illustrated by specific embodiments.

Refer to <FIG>, which is a schematic diagram showing a structure of an implementation environment provided by an embodiment of the present invention. The implementation environment includes: an automobile <NUM> and a tyre pressure monitoring assistance tool <NUM>. The automobile <NUM> is provided with a vehicle-mounted OBD interface <NUM> and a tyre pressure monitoring system <NUM>; the tyre pressure monitoring system <NUM> includes a tyre pressure monitoring unit <NUM> and a sensor <NUM>; the vehicle-mounted OBD interface <NUM> is connected to the tyre pressure monitoring unit <NUM> via a bus; the tyre pressure monitoring assistance tool <NUM> is connected to the tyre pressure monitoring unit <NUM> via the vehicle-mounted OBD interface <NUM>; at this moment, the tyre pressure monitoring assistance tool <NUM> can read a data stream of the tyre pressure monitoring unit <NUM> via the vehicle-mounted OBD interface <NUM>; in an embodiment of the present invention, the data stream comprises recorded measurement data.

Specifically, the tyre pressure monitoring unit <NUM> stores a sensor identification code and a radio frequency communication protocol, and the tyre pressure monitoring unit <NUM> can identify a radio frequency signal of the corresponding sensor through the sensor identification code and can accurately receive the radio frequency signal of the corresponding sensor through the radio frequency communication protocol. As one of the implementation modes, the sensor identification code stored in the tyre pressure monitoring unit <NUM> is the sensor identification code of the sensor <NUM>.

It can be understood that, in the process of the tyre pressure monitoring unit <NUM> receiving the radio frequency signal, only when the radio frequency communication protocol of the tyre pressure monitoring unit <NUM> is consistent with the radio frequency communication protocol of the corresponding sensor, the tyre pressure monitoring unit <NUM> can receive the radio frequency signal of the corresponding sensor, and can demodulate and obtain the recorded measurement data consistent with the measurement data carried in the radio frequency signal.

Based on this, an embodiment of the present invention judges whether the radio frequency communication protocol of the tyre pressure monitoring unit <NUM> is the same as the radio frequency communication protocol simulated by the tyre pressure monitoring assistance tool <NUM> by determining whether the recorded measurement data consistent with the simulation measurement data carried by the radio frequency signal can be read through the vehicle-mounted OBD interface <NUM> after the tyre pressure monitoring assistance tool <NUM> simulates the candidate radio frequency communication protocol of the tyre pressure monitoring unit <NUM> to send the radio frequency signal to the tyre pressure monitoring unit <NUM>. When the radio frequency communication protocol of the tyre pressure monitoring unit <NUM> is the same as the radio frequency communication protocol simulated by the tyre pressure monitoring assistance tool <NUM>, the radio frequency communication protocol simulated by the tyre pressure monitoring assistance tool <NUM> can be determined as the actual radio frequency communication protocol of the tyre pressure monitoring unit <NUM>, and the determination of the radio frequency communication protocol of the tyre pressure monitoring unit can be realized. Since the radio frequency communication protocol of the tyre pressure monitoring unit <NUM> is unique, after determining the radio frequency communication protocol of the tyre pressure monitoring unit <NUM>, displaying the function menu interface of the tyre pressure monitoring system according to the radio frequency communication protocol of the tyre pressure monitoring unit <NUM> can improve the accuracy of positioning the function menu interface of the automobile tyre pressure monitoring system.

In an embodiment of the present invention, the radio frequency unit <NUM> can simulate a candidate radio frequency communication protocol of the tyre pressure monitoring unit <NUM> to send a radio frequency signal to the tyre pressure monitoring unit <NUM>, the radio frequency signal being in an RF frame format.

The OBD interface <NUM> is then used to be electrically connected to the vehicle-mounted OBD interface <NUM> to establish a communication connection with the tyre pressure monitoring unit <NUM>.

The interaction unit <NUM> is then used to interact with a user, including outputting display content to the user and/or receiving an input operation from the user.

It can be understood that when the user connects the OBD interface <NUM> of the tyre pressure monitoring assistance tool <NUM> with the vehicle-mounted OBD interface <NUM> of the automobile and starts the method for displaying a function menu interface of the automobile tyre pressure monitoring system, the tyre pressure monitoring assistance tool <NUM> reminds the user to input vehicle information of the automobile via the interaction module <NUM>, and receives a trigger operation carrying the vehicle information via the interaction module <NUM>, so as to determine the vehicle information carried by the trigger operation as the vehicle information of the automobile; then, the tyre pressure monitoring assistance tool <NUM> determines a candidate radio frequency communication protocol of the tyre pressure monitoring unit <NUM> according to vehicle information of the automobile, and sends a radio frequency signal to the tyre pressure monitoring unit <NUM> via the radio frequency unit <NUM> simulating the candidate radio frequency communication protocol, wherein the radio frequency signal comprises a sensor identification code and simulation measurement data; if the tyre pressure monitoring assistance tool <NUM> reads recorded measurement data corresponding to the sensor identification code in the tyre pressure monitoring unit <NUM> via the OBD interface <NUM>, and the recorded measurement data is consistent with the simulation measurement data, the candidate radio frequency communication protocol is determined to be an actual radio frequency communication protocol of the tyre pressure monitoring unit <NUM>; the tyre pressure monitoring assistance tool <NUM> displays the function menu interface of the tyre pressure monitoring system according to the actual radio frequency communication protocol, and outputs the function menu interface of the tyre pressure monitoring system to the interaction unit <NUM> for display. Since the radio frequency communication protocol of the tyre pressure monitoring unit <NUM> in the automobile tyre pressure monitoring system is unique, the function menu interface of the automobile tyre pressure monitoring system can be accurately positioned through the actual radio frequency communication protocol of the tyre pressure monitoring unit <NUM>.

Further, refer to <FIG>, which is a schematic flow diagram of a method for displaying a function menu interface of an automobile tyre pressure monitoring system provided by an embodiment of the present invention. The method for displaying a function menu interface of an automobile tyre pressure monitoring system is applied to the above-mentioned tyre pressure monitoring assistance tool. As one specific implementation mode, the method for displaying a function menu interface of an automobile tyre pressure monitoring system is executed by the above-mentioned processor <NUM>, and can accurately position the function menu interface of the automobile tyre pressure monitoring system.

Specifically, the method for displaying a function menu interface of an automobile tyre pressure monitoring system comprises:
S100, acquiring vehicle information of an automobile.

In an embodiment of the present invention, the vehicle information of an automobile comprises: vehicle series, vehicle model, and model year.

The vehicle information of an automobile can be obtained either by reading the VIN code of the automobile or by user input.

When the vehicle information of an automobile is obtained through user input, the user-triggered trigger operation carrying the vehicle information is received, and the vehicle information carried by the trigger operation is determined to be the vehicle information of the automobile.

It can be understood that, in the embodiment of the present invention, since the vehicle information of an automobile includes only the vehicle series, the vehicle model, and the model year, the redundancy of user input of the vehicle information is reduced. Therefore, it is possible to avoid the user's input error of the vehicle information during the process of inputting the vehicle information.

S200, on the basis of the vehicle information, determine a candidate radio frequency communication protocol of a tyre pressure monitoring unit.

In an embodiment of the present invention, when on the basis of the vehicle information, determining a candidate radio frequency communication protocol of a tyre pressure monitoring unit is performed, a candidate automobile matching the vehicle information is searched in the automobile database, and the radio frequency communication protocol corresponding to the candidate automobile is determined as the candidate radio frequency communication protocol of the tyre pressure monitoring unit. The automobile database records detailed information of all automobiles leaving the factory.

Since only one radio frequency communication protocol exists in the tyre pressure monitoring unit of each automobile, if the automobile can be uniquely determined according to the vehicle information of the automobile, one candidate radio frequency communication protocol exists; and if the automobile cannot be uniquely determined according to the vehicle information of the automobile, there are at least two candidate radio frequency communication protocols.

When one candidate radio frequency communication protocol exists, the candidate radio frequency communication protocol is directly determined as the actual radio frequency communication protocol of the tyre pressure monitoring unit.

When there are at least two candidate radio frequency communication protocols, steps S300-S400 are executed.

S300, by means of a radio frequency unit simulating the candidate radio frequency communication protocol, send a radio frequency signal to the tyre pressure monitoring unit, the radio frequency signal comprising a sensor identification code and simulation measurement data.

In an embodiment of the invention, the radio frequency unit modulates a sensor identification code and simulation measurement data into an RF frame format via simulating a candidate radio frequency communication protocol to obtain a radio frequency signal, whereby the radio frequency signal comprises the sensor identification code and the simulation measurement data. Based on this, it can be understood that the simulation measurement data is substantially the original data before the modulation. Therefore, when the candidate radio frequency communication protocol comprises two or more, in order to accurately determine the actual radio frequency communication protocol of the tyre pressure monitoring unit, the simulation measurement data of the radio frequency signals sent by the radio frequency unit simulating each candidate radio frequency communication protocol is the same. Of course, in some embodiments, where the simulation measurement data of the radio frequency signals sent by the radio frequency unit simulating each candidate radio frequency communication protocol is different, solutions of embodiments of the present invention can also be implemented.

The radio frequency signal is in an RF frame format. As shown in <FIG>, the RF frame format comprises a synchronization head, a sensor identification code, simulation measurement data, and a check code, wherein the synchronization head and the check code can be automatically generated during the modulation process of the radio frequency signal.

The sensor identification code is acquired from the tyre pressure monitoring unit so as to ensure that the radio frequency signal sent by the radio frequency unit simulating the candidate radio frequency communication protocol can be identified by the tyre pressure monitoring unit. For this reason, it is necessary to acquire the sensor identification code before the step of sending the radio frequency signal to the tyre pressure monitoring unit through the radio frequency unit simulating the candidate radio frequency communication protocol.

Specifically, when the sensor identification code is acquired, it is determined whether the sensor identification code is stored in the tyre pressure monitoring unit; if the sensor identification code is stored in the tyre pressure monitoring unit, the sensor identification code is read from the tyre pressure monitoring unit via the OBD interface; if the tyre pressure monitoring unit does not store the sensor identification code, the user is prompted to write the sensor identification code, including the user being prompted to write the sensor identification code into the tyre pressure monitoring unit and write the sensor identification code into the tyre pressure monitoring assistance tool.

The simulation measurement data is set by the user, and the simulation measurement data can be set as a random numerical value. In an embodiment of the invention, the simulation measurement data comprises at least one of pressure data, temperature data, and acceleration data. Based on this, when the type of the simulation measurement data is more than one, the numerical values of the simulation measurement data need to be set respectively according to the type of the simulation measurement data. For example, when the simulation measurement data includes pressure data and temperature data, the numerical value of the pressure data and the numerical value of the temperature data need to be set.

Preferably, an embodiment of the present invention selects pressure data as the simulation measurement data.

S400, if recorded measurement data corresponding to the sensor identification code is read out from the tyre pressure monitoring unit by means of the OBD interface, and the recorded measurement data is consistent with the simulation measurement data, then determine that the candidate radio frequency communication protocol is the actual radio frequency communication protocol of the tyre pressure monitoring unit.

In an embodiment of the present invention, the recorded measurement data is data obtained after demodulating the radio frequency signal by the radio frequency communication protocol of the tyre pressure monitoring unit.

Since only when the radio frequency communication protocol of the tyre pressure monitoring unit is the same as the radio frequency communication protocol simulated by the radio frequency unit, the tyre pressure monitoring unit can receive the radio frequency signal and demodulate the radio frequency signal to obtain the recorded measurement data consistent with the simulation measurement data carried in the radio frequency signal, whether the radio frequency communication protocol of the tyre pressure monitoring unit is the same as the radio frequency communication protocol simulated by the radio frequency unit can be judged by determining whether the recorded measurement data consistent with the simulation measurement data can be read through the OBD interface; when the radio frequency communication protocol of the tyre pressure monitoring unit is the same as the radio frequency communication protocol simulated by the radio frequency unit, then the radio frequency communication protocol simulated by the radio frequency unit can be determined as the radio frequency communication protocol of the tyre pressure monitoring unit such that the determination of the radio frequency communication protocol for the tyre pressure monitoring unit can be achieved.

It can be understood that when at least two candidate radio frequency communication protocols comprise a first candidate radio frequency communication protocol and a second candidate radio frequency communication protocol, the tyre pressure monitoring assistance tool sends a first radio frequency signal to the tyre pressure monitoring unit via the radio frequency unit simulating the first candidate radio frequency communication protocol, wherein the first radio frequency signal comprises a sensor identification code and simulation measurement data; at this moment, if the tyre pressure monitoring assistance tool reads recorded measurement data corresponding to the sensor identification code of the first radio frequency signal in the tyre pressure monitoring unit via the OBD interface, and the recorded measurement data is consistent with the simulation measurement data of the first radio frequency signal, then it is determined that the first candidate radio frequency communication protocol is an actual radio frequency communication protocol of the tyre pressure monitoring unit; if the tyre pressure monitoring assistance tool does not read the recorded measurement data corresponding to the sensor identification code of the first radio frequency signal in the tyre pressure monitoring unit via the OBD interface, or if the tyre pressure monitoring assistance tool reads the recorded measurement data corresponding to the sensor identification code of the first radio frequency signal in the tyre pressure monitoring unit via the OBD interface and the recorded measurement data is inconsistent with the simulation measurement data of the first radio frequency signal, the tyre pressure monitoring assistance tool sends a second radio frequency signal to the tyre pressure monitoring unit via the radio frequency unit simulating a second candidate radio frequency communication protocol, wherein the second radio frequency signal comprises the sensor identification code and the simulation measurement data; at this time, if the tyre pressure monitoring assistance tool reads the recorded measurement data corresponding to the sensor identification code of the second radio frequency signal in the tyre pressure monitoring unit through the OBD interface, and the recorded measurement data is consistent with the simulation measurement data of the second radio frequency signal, it is determined that the second candidate radio frequency communication protocol is the actual radio frequency communication protocol of the tyre pressure monitoring unit.

It can be understood that when the candidate radio frequency communication protocol includes two or more, the respective candidate radio frequency communication protocols are different from each other, and one and only one of the candidate radio frequency communication protocols is the actual radio frequency communication protocol of the tyre pressure monitoring unit.

Further, in some embodiments, in order to ensure the accuracy of the result, before the step of determining that the candidate radio frequency communication protocol is the actual radio frequency communication protocol of the tyre pressure monitoring unit, the candidate radio frequency communication protocol is determined to be a pending radio frequency communication protocol, and the step of simulating the pending radio frequency communication protocol to send a radio frequency signal to the tyre pressure monitoring unit is repeated at least once; if during the process that simulating the pending radio frequency communication protocol to send a radio frequency signal to the tyre pressure monitoring unit is repeated at least once, the pending radio frequency communication protocol can be determined to be the actual radio frequency communication protocol of the tyre pressure monitoring unit, then the candidate radio frequency communication protocol is determined to be the actual radio frequency communication protocol of the tyre pressure monitoring unit.

For example, before it is determined that the first candidate radio frequency communication protocol is the actual radio frequency communication protocol of the tyre pressure monitoring unit, the first candidate radio frequency communication protocol is determined to be a pending radio frequency communication protocol; the tyre pressure monitoring assistance tool again simulates the pending candidate radio frequency communication protocol via the radio frequency unit to send a third radio frequency signal to the tyre pressure monitoring unit, wherein the third radio frequency signal comprises sensor identification code and simulation measurement data; at this time, if the tyre pressure monitoring assistance tool reads the recorded measurement data corresponding to the sensor identification code of the third radio frequency signal in the tyre pressure monitoring unit via the OBD interface, and the recorded measurement data is consistent with the simulation measurement data of the third radio frequency signal, then it is determined that the pending candidate radio frequency communication protocol is the actual radio frequency communication protocol of the tyre pressure monitoring unit; then, the tyre pressure monitoring assistance tool again simulates the pending candidate radio frequency communication protocol to send a fourth radio frequency signal to the tyre pressure monitoring unit via the radio frequency unit, wherein the fourth radio frequency signal comprises sensor identification code and simulation measurement data; at this time, if the tyre pressure monitoring assistance tool reads the recorded measurement data corresponding to the sensor identification code of the fourth radio frequency signal in the tyre pressure monitoring unit via the OBD interface, and recorded measurement data is consistent with the simulation measurement data of the fourth radio frequency signal, then it is determined that the pending candidate radio frequency communication protocol is the actual radio frequency communication protocol of the tyre pressure monitoring unit; since it is possible to determine that the pending radio frequency communication protocol is the actual radio frequency communication protocol of the tyre pressure monitoring unit after simulating the pending radio frequency communication protocol to send the radio frequency signal to the tyre pressure monitoring unit is repeated twice, the first candidate radio frequency communication protocol is determined to be the actual radio frequency communication protocol of the tyre pressure monitoring unit.

The numerical value of the simulation measurement data of the first radio frequency signal, the numerical value of the simulation measurement data of the third radio frequency signal, and the numerical value of the simulation measurement data of the fourth radio frequency signal may be the same or different.

S500, on the basis of the actual radio frequency communication protocol, display a function menu interface of the tyre pressure monitoring system.

Specifically, when on the basis of the actual radio frequency communication protocol, displaying a function menu interface of the tyre pressure monitoring system is performed, after positioning an automobile according to the actual radio frequency communication protocol, the function menu interface of the automobile tyre pressure monitoring system is started according to the menu of the automobile, and the function menu interface is sent to the interaction unit for display. Since the radio frequency communication protocol of the tyre pressure monitoring unit in the automobile tyre pressure monitoring system is unique, the automobile tyre pressure monitoring system can be uniquely determined according to the actual radio frequency communication protocol of the tyre pressure monitoring unit, and then the function menu interface of the automobile tyre pressure monitoring system can be accurately positioned.

The function menu interface of the tyre pressure monitoring system is used for displaying menu information of the tyre pressure monitoring system. Specifically, the function menu interface can be used for displaying an icon corresponding to each functional module for a user to select a corresponding implementation function according to the icon so as to realize a functional operation with the tyre pressure detection system. The functional module displayed by the function menu interface comprises functions such as sensor activation, sensor programming, and sensor part number query. The operations such as the maintenance of the tyre pressure detection system can be completed via a functional module provided by the function menu interface.

It can be understood that in an embodiment of the present invention, whether the radio frequency communication protocol of the tyre pressure monitoring unit is the same as the radio frequency communication protocol simulated by the radio frequency unit is judged by determining whether the recorded measurement data consistent with the simulation measurement data can be read via the OBD interface; when the radio frequency communication protocol of the tyre pressure monitoring unit is the same as the radio frequency communication protocol simulated by the radio frequency unit, the radio frequency communication protocol simulated by the radio frequency unit can be determined as the radio frequency communication protocol of the tyre pressure monitoring unit, and the radio frequency communication protocol of the tyre pressure monitoring unit can be accurately determined, and further, the function menu interface of the tyre pressure monitoring system can be accurately positioned according to the radio frequency communication protocol of the tyre pressure monitoring unit, so as to improve the accuracy of positioning the function menu interface of the automobile tyre pressure monitoring system.
