[0045] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0046] The components of the embodiments of the present application that are generally described and illustrated in the accompanying drawings herein may be arranged and designed in a variety of different configurations. Accordingly, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but is merely representative of selected embodiments of the present application.

In addition, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0048] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art to which the various embodiments of the present application belong. The terms (such as those defined in a commonly used dictionary) will be interpreted as having the same meaning as the contextual meaning in the relevant technical field and will not be interpreted as having an idealized meaning or being overly formal, unless clearly defined in the various embodiments of the present application.

[0049] The following describes in detail some embodiments of the present application in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0050] Considering the problems in the prior art that relying on the dashboard or the central control screen to display the tire pressure information causes the driver's line of sight to leave the road, thereby increasing the risk of accidents and causing unpredictable injuries, etc., the present application provides a vehicle tire pressure monitoring method, system and MR glasses. Through the MR glasses, the tire pressure data is directly graphically presented within the driver's field of vision. While viewing the tire pressure data, the driver can also view the road conditions in front of the vehicle in real time, achieving a balance between information acquisition and driving safety. And when the tire pressure data exceeds the preset tire pressure threshold range, an alarm is given, enabling the driver to timely discover abnormal tire pressure and further ensuring the driving safety of the vehicle.

[0051] The MR glasses are a device that can combine virtual digital content with the real environment, enabling users to see and interact with three-dimensional virtual objects in the real environment. Through transparent or semi-transparent lenses, the wearer can simultaneously see the physical world and the digital information superimposed thereon. These devices use cameras and sensors to track the user's position in space and actions such as gestures and eye movements, thereby enabling the operation of virtual objects. When the driver is driving the vehicle and wears the MR glasses, the tire pressure data can be directly visualized in the driver's field of vision, greatly ensuring the safety of the driver.

[0052] The following will illustrate the vehicle tire pressure monitoring method in conjunction with some specific embodiments.

[0053] Figure 1 FIG. shows a schematic flowchart of a vehicle tire pressure monitoring method according to an embodiment of the present application. This vehicle tire pressure monitoring method is applied to the MR glasses worn by the driver and is executed by the processor in the MR glasses. Exemplarily, this monitoring method includes S101 - S104:

[0054] S101, obtaining the original tire pressure data collected by each tire pressure sensor module of the vehicle.

[0055] The MR glasses can be communicatively connected to each tire pressure sensor module of the vehicle, thereby obtaining the original tire pressure data collected by each tire pressure sensor module. It can be understood that the tire pressure sensor module can only collect the air pressure value of each tire of the vehicle, and the tire pressure sensor module can also collect data such as the battery power of the tire pressure sensor and the temperature of the tire.

[0056] Furthermore, to ensure the integrity of data reception, as Figure 2 shown, after S101, the monitoring method further includes S201 - S202:

[0057] S201, performing data verification on the data frames of each original tire pressure data.

[0058] It can be understood that the data frame includes the start bit, end bit, data length, ID field, check field, and data field of the data frame, etc. Among them, the ID field of the data frame can be the identifier of the tire pressure sensor module, the data length represents the length of the valid data in the data frame, and the data field includes measured values such as tire pressure and temperature.

[0059] Parity check can be performed on the data frame, or cyclic redundancy check can be performed on the data frame, or longitudinal redundancy check can be performed on the data frame. By verifying the data frame, errors in the transmission process of the data frame can be avoided.

[0060] S202, if there is at least one error in the original tire pressure data, sending a data retransmission request to the tire pressure sensor module associated with the data error.

[0061] If at least one piece of original tire pressure data is incorrect, a data retransmission request is sent to the tire pressure sensor module associated with the data error, so that the tire pressure sensor module re-collects the tire pressure data after receiving the data retransmission request and re-sends it to the MR glasses. By performing data verification on the original tire pressure data collected by the tire pressure sensor module, the integrity and accuracy of the data are ensured.

[0062] S102. Preprocess each piece of original tire pressure data to obtain each piece of processed tire pressure data.

[0063] Exemplarily, data cleaning and noise filtering can be performed on the original tire pressure data to smooth the data curve and reduce the influence of high-frequency noise. Feature extraction can also be performed on the original tire pressure data to extract meaningful features.

[0064] For example, in one implementation, as Figure 3 shown, S102 includes the following sub-steps:

[0065] S301. Parse the original tire pressure data according to a preset data transmission protocol to obtain the first tire pressure data.

[0066] Specifically, the data transmission protocol refers to a protocol that stipulates the meanings and positions of the various fields of the data frame. For example, it stipulates that the first byte range represents the tire number, the second byte range represents the coding method of the air pressure value, and the third byte range represents the device identification information of the tire pressure sensor module, etc.

[0067] Through the parsing of the original tire pressure data, information such as the tire pressure of each tire of the vehicle, the power status of each tire pressure sensor module, the temperature of each tire, and the data acquisition timestamp obtained are used as the first tire pressure data. Further, the first tire pressure data can be stored in a structured data structure for easy processing and transmission of the information.

[0068] S302. Verify the first tire pressure data to obtain the processed tire pressure data.

[0069] Range verification can be performed on the first tire pressure data. For example, check whether the pressure of each tire is within the preset tire pressure range; consistency verification can also be performed on the parsed information. For example, compare whether the air pressures of different tires conform to the normal driving logic of the vehicle; redundancy verification can also be performed on the parsed information, etc.

[0070] Further, as Figure 4 shown, after verifying the first tire pressure data, the monitoring method further includes S401 - S402:

[0071] S401. If the first tire pressure data is detected as incorrect, use a data error correction algorithm to repair the incorrect data.

[0072] If an error occurs in the first tire pressure data detection data, a data error correction algorithm is used for repair. For example, speculative repair is performed using the historical trend of the data and the correlation of adjacent data.

[0073] S402, if the repair fails, mark the error data and trigger an alarm mechanism.

[0074] If the repair fails, mark the error data and trigger an alarm mechanism for alarm. It can be understood that the alarm mechanism can be triggered to alarm using multiple alarm methods or a single alarm method. Further, abnormal data can be recorded for subsequent troubleshooting and analysis. By verifying and repairing the parsed data, the accurate transmission of data is guaranteed, data delay and packet loss are avoided, and the driver can obtain tire pressure data in real time and accurately, greatly improving the stability of the system.

[0075] S103, perform graphical processing on each processed tire pressure data and project it onto the virtual display interface of the MR glasses for dynamic display.

[0076] The processed tire pressure data can be graphically and dynamically displayed according to the actual application situation. For example, the tire pressure change of the tire can be simulated to display the tire shape. Further, the real-time air pressure values of each tire can also be displayed in text. Or, a line chart is generated according to the tire pressure change of each tire, so that the driver can intuitively obtain the tire pressure change. By using the virtual display interface of the MR glasses, the driver can intuitively understand the tire pressure of each tire, and can quickly judge whether the tire pressure of the vehicle is normal without spending energy on interpreting or memorizing the data meaning, greatly improving the safety of the driving process and further ensuring the safety of the driver.

[0077] Further, the virtual display interface of the MR glasses can automatically adjust the parameters of the display interface according to the ambient light, such as the brightness and contrast of the interface, to ensure the clarity of the tire pressure data and avoid the influence of the external environment on the driver's acquisition of tire pressure data, and adapt to various driving environments.

[0078] S104, trigger an alarm mechanism if any of the processed tire pressure data exceeds the preset tire pressure threshold range.

[0079] It can be understood that the tire pressure threshold can be set according to the actual application situation. The tire pressure threshold can be a fixed tire pressure threshold, or the tire pressure threshold can be a dynamic tire pressure threshold. For example, the tire pressure threshold can be dynamically adjusted according to one or more of vehicle type parameters, vehicle driving parameters, environmental parameters, and tire health. For example, the standard tire pressure of the vehicle is 2.3 bar. When the tire wear degree of the vehicle reaches 20%, the tire pressure threshold is lowered by 0.2 bar.

[0080] Compare each processed tire pressure data with the tire pressure threshold to determine whether each processed tire pressure data is within the tire pressure threshold range. Further, compensate each processed tire pressure data according to the environmental parameters of the vehicle to obtain each compensated tire pressure, and use each compensated tire pressure to compare with the tire pressure threshold; the compensated tire pressure is obtained through the following formula:

[0081] P adj =P base *[1 + 0.0035*(T c -T r )]

[0082] where, P adj represents the compensated tire pressure, P base represents the current tire pressure, T c represents the environmental temperature of the vehicle, T r represents the reference temperature.

[0083] The tire pressure threshold range can be set according to the actual application situation, and the tire pressure threshold range can be set according to the road on which the vehicle travels. For example, when it is determined through the camera function of the MR glasses that the vehicle is traveling on an urban road, the urban tire pressure threshold range is adopted. For example, the urban tire pressure threshold range is ±10% of the tire pressure threshold; when it is determined through the camera function of the MR glasses that the vehicle is traveling on a wilderness road, the wilderness road tire pressure threshold range is adopted. For example, the wilderness road tire pressure threshold range is ±15% of the tire pressure threshold.

[0084] Further, the tire pressure threshold range can be dynamically adjusted according to one or more of the road condition data, vehicle operation data, and environmental factor data. For example, preprocess each collected road condition data, vehicle operation data, and environmental factor data, select a model such as a convolutional neural network or a recurrent neural network, transmit each processed data to the model for training, and deploy the trained model to the MR glasses so that it can receive the road condition data in real time and output the tire pressure threshold range.

[0085] Furthermore, when the tire pressure of any one tire exceeds the tire pressure threshold range, an alarm mechanism is triggered. It is understandable that a sound alarm, a vibration alarm, or a visual alarm can be carried out. For example, icon flashing, colored text, etc. are carried out. Further, the alarm level can be set according to the tire pressure threshold range.

[0086] Specifically, the tire pressure threshold range includes a first tire pressure threshold range, a second tire pressure threshold range, and a third tire pressure threshold range. If the tire pressure data is not within the first tire pressure threshold range, the alarm mechanism is triggered for a first-level alarm, and the first-level alarm includes a vibration alarm and a text alarm. For example, when the tire pressure of the vehicle is within ±15% of the tire pressure threshold, the icon on the virtual reality interface is controlled to change color and the MR glasses are controlled to generate a short vibration.

[0087] If the tire pressure data is not within the second tire pressure threshold range, the alarm mechanism is triggered for a second-level alarm, and the second-level alarm includes a sound alarm and a light alarm. For example, when the tire pressure of the vehicle exceeds ±15% of the tire pressure threshold but is within ±25% of the tire pressure threshold, the MR glasses are controlled for voice prompts and light flashing prompts.

[0088] If the tire pressure data is not within the third tire pressure threshold range, the alarm mechanism is triggered for a third-level alarm, and the third-level alarm includes an audible and visual alarm and a vibration alarm. For example, when the tire pressure of the vehicle exceeds ±25% of the tire pressure threshold, the virtual reality interface of the MR glasses is controlled to generate a red background, and the MR glasses are controlled for voice prompts and strong vibrations. Further, the alarm level can be set according to the number of abnormal tire pressures of the vehicle.

[0089] When the tire pressure is abnormal, the alarm information is prompted to the driver through various modes such as audio, vision, and vibration, ensuring that the driver can detect the abnormal tire pressure in a timely manner in various driving environments, facilitating timely response measures, avoiding traffic accidents caused by abnormal tire pressure, and ensuring the driving safety of the vehicle.

[0090] Further, the MR glasses are communicatively connected to the vehicle's central control system, and the vehicle's central control system is communicatively connected to the tire pressure sensor module, capable of obtaining the tire pressures of each tire of the vehicle through the tire pressure sensors. When the MR glasses are low on power or have other abnormalities, they can be communicatively connected to the central control system to obtain historical data through the central control system. When the central control system transmits data to the MR glasses, to avoid situations such as network fluctuations or the MR glasses being offline, a data caching mechanism is adopted to cache the currently transmitted data locally for a preset time. If the MR glasses and the central control system resume connection, the central control system reads the data that was not successfully transmitted from the cache and retransmits it to ensure the continuity and integrity of the tire pressure data.

[0091] In an alternative embodiment, as Figure 5 shown, before S101, the monitoring method further includes S501 - S502:

[0092] S501, perform a Bluetooth search on the device identification information of each tire pressure sensor module.

[0093] Further, before performing a Bluetooth search on each tire pressure sensor module, the processor can first perform a self-check on each module in the MR glasses. For example, it checks the read and write functions of the memory, checks the connection status of the Bluetooth chip, and checks whether each component is working properly. If a fault is found, an alarm can be issued and an attempt can be made to repair the fault to ensure the safety of the device.

[0094] S502, in the case of successfully searching for each tire pressure sensor module, perform encrypted pairing with each searched tire pressure sensor module to obtain the original tire pressure data of the tire pressure sensor module with which the pairing is successful.

[0095] Perform encrypted pairing with each tire pressure sensor module according to a preset pairing password to prevent data from being stolen or tampered with during transmission, ensure the security and uniqueness of the connection, and prevent unauthorized Bluetooth devices from connecting to the MR glasses. After successful pairing, store the parameter information of the tire pressure sensor module with which the pairing is successful in the local database for subsequent identification and connection.

[0096] After successful pairing with the tire pressure sensor module, enter the data reception loop, and monitor the Bluetooth broadcast data from the tire pressure sensor module through the listening function of the Bluetooth chip to ensure reliable data transmission.

[0097] Further, the processor continuously monitors the Bluetooth connection. If the Bluetooth is interrupted or the signal quality deteriorates, an attempt can be made to reconnect to the tire pressure sensor module through the Bluetooth chip. If the attempt to reconnect fails multiple times, a Bluetooth connection failure alarm is issued to the driver, and fault information such as the connection failure time, the number of connection attempts, and the connection strength before the fault is recorded for subsequent fault troubleshooting and repair.

[0098] In this embodiment, each tire pressure sensor module and the MR glasses perform encrypted pairing through low-power Bluetooth, ensuring the integrity and security of the data.

[0099] As Figure 6 shown, based on the method of the above embodiment, this embodiment provides a vehicle tire pressure monitoring system. Exemplarily, the monitoring system 100 includes:

[0100] A data acquisition module 110 that acquires the original tire pressure data collected by each tire pressure sensor module of the vehicle;

[0101] A data processing module 120 that preprocesses each original tire pressure data to obtain each processed tire pressure data;

[0102] A dynamic display module 130 that performs graphical processing on each processed tire pressure data and projects it in the virtual display interface of the MR glasses for dynamic display;

[0103] The warning control module 140 triggers the warning mechanism when any of the processed tire pressure data exceeds the preset tire pressure threshold range.

[0104] It can be understood that the system of this embodiment corresponds to the control method of the above embodiment. The optional items in the above embodiment are equally applicable to this embodiment, so they will not be described repeatedly here.

[0105] This application also provides an MR glasses. Exemplarily, the MR glasses include a processor and a memory. Among them, the memory stores a computer program, and the processor runs the computer program to enable the device to execute the functions of the above vehicle tire pressure monitoring method or each module in the above vehicle tire pressure monitoring system.

[0106] Using the MR glasses, the tire pressure data is directly presented graphically within the driver's field of vision, without the need to take the eyes off the road, greatly reducing the risk of accidents and ensuring the safety of the driver.

[0107] Furthermore, the MR glasses can be communicatively connected to the driving assistance system. When the tire pressure data is abnormal, a tire pressure abnormal signal is sent to the driving assistance system, enabling the driving assistance system to adjust the driving control of the vehicle, thereby improving the safety and intelligence of the vehicle in the driving environment.

[0108] The MR glasses can also be connected to the adjustment system of the vehicle. When the tire pressure data affects the riding comfort, the adjustment system adjusts the relevant parameters, greatly improving the user experience.
