[0015] To more clearly illustrate the technical solutions of the embodiments of this specification, the following briefly describes the drawings required for describing the embodiments. Obviously, the drawings described below are merely examples or embodiments of this specification. Those skilled in the art can apply this specification to other similar scenarios based on these drawings without inventive effort. Unless otherwise apparent from the context or otherwise noted, the same reference numerals in the figures represent the same structure or operation.

[0016] It should be understood that the terms "system," "device," "unit," and / or "module" used herein are a method for distinguishing different components, elements, parts, portions, or assemblies at different levels. However, if other terms can achieve the same purpose, the terms may be replaced by other expressions.

[0017] As used in this specification and claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" do not refer to the singular but also include the plural. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.

[0018] Flowcharts are used throughout this specification to illustrate the operations performed by systems according to embodiments of this specification. It should be understood that preceding or following operations do not necessarily need to be performed in exact order. Instead, the steps may be processed in reverse order or simultaneously. Furthermore, other operations may be added to these processes, or one or more operations may be removed from these processes.

[0019] Tire runout is a common fault on two-wheeled vehicles. It not only affects the rider's riding experience but also poses certain safety risks. In some cases, the diagnosis of tire runout on two-wheeled vehicles often relies on the maintenance personnel's experience. This method is highly subjective and lacks unified standards. Furthermore, the diagnostic accuracy may be low when the runout amplitude is small.

[0020] Some embodiments of the present specification provide a method, device, and system for diagnosing tire runout. The method comprises fixing a tire and a diagnostic device on a detection frame, wherein a laser transmitter in the diagnostic device transmits a laser beam vertically toward the surface of the tire, and a laser receiver receives the laser beam reflected by the tire surface. A processor in the diagnostic device can determine the distance between the laser receiver and the tire surface based on the reflected laser beam. If the distance between the laser receiver and the tire surface has not changed (or the change is less than a preset threshold), it indicates that the reflection point of the laser beam on the tire surface has not changed (or the change is small), and the relative position of the tire and the laser transmitter has not changed (or the change is small), that is, the tire has not runout (or the runout amplitude is small). If the change in the distance between the laser receiver and the tire surface is greater than the preset threshold, it indicates that the reflection point of the laser beam on the tire surface has also changed significantly, and the relative position of the tire and the laser transmitter has also changed significantly, that is, the tire has runout, and the runout amplitude is large.

[0021] Some embodiments of the present specification provide a method, device, and system for diagnosing tire wobble, which can at least obtain electrical and information-based capabilities, automate, intelligentize, and standardize the diagnosis process of tire wobble failure, and can visually diagnose tire wobble conditions, and more intuitively and accurately determine whether the tire is wobble, as well as the wobble amplitude when wobble occurs.

[0030] The storage device 160 is capable of storing data, instructions, and / or any other information. In some embodiments, the storage device 160 can store data obtained from the diagnostic device 120 or the server 150. For example, a diagnostic record of a tire runout fault, a chart reflecting the change in the distance between the tire surface and the laser receiver, etc. In some embodiments, the storage device 160 may include a large-capacity memory, a removable memory, a volatile read-write memory, a read-only memory (ROM), etc., or any combination thereof. In some embodiments, the storage device 160 can be executed on a cloud platform. In some embodiments, the storage device 160 can be connected to the network 130 to communicate with one or more other components of the application scenario 100 (e.g., the diagnostic device 120, the server 150, etc.).

[0031] It is worth noting that the application scenario 100 of the tire runout diagnostic device is provided for illustrative purposes only and is not intended to limit the scope of this specification. A person skilled in the art can make various changes and modifications based on the description of this specification. For example, the application scenario 100 of the tire runout diagnostic device may also include a database, an information source, and the like. For another example, the application scenario 100 of the tire runout diagnostic device may be implemented on other devices to achieve similar or different functions. However, such changes and modifications do not deviate from the scope of this specification.

[0032] Figure 2 FIG. 1 is a schematic diagram of a tire runout diagnosis device according to some embodiments of this specification. Figure 2 As shown, the tire runout diagnostic device 120 (hereinafter referred to as the diagnostic device 120 ) includes a sensor 121 , a communication module 122 and a processor 123 .

[0033] The sensor 121 includes a laser emitter 1211 and a laser receiver 1212 .

[0034] The laser emitter 1211 is configured to emit a laser beam (eg, a pulsed laser beam) perpendicular to the tire surface toward the tire surface.

[0035] The laser receiver is configured to receive the laser beam reflected from the tire surface.

[0036] The communication module 122 is configured to communicate with the terminal device 140. For example, the communication module 122 may be a Bluetooth Low Energy (BLE) module, etc. The communication module 122 may also be other modules with communication functions, which are not limited here.

[0037] The processor 123 may include a central processing unit (CPU), a digital signal processor (DSP), a microcontroller unit (MCU), etc., or any combination thereof.

[0038] In some embodiments, the processor 123 is configured to: receive a runout diagnostic instruction from the terminal device 140; based on the runout diagnostic instruction, control the laser emitter 1211 to emit a laser beam perpendicular to the tire surface to the tire surface; control the laser receiver 1212 to receive the laser beam reflected from the tire surface; based on the reflected laser beam, generate a chart reflecting the change in distance between the tire surface and the laser receiver 1212; send the chart to the terminal device 140, and display the chart on the terminal device 140.

[0039] In some embodiments, the processor 123 is further configured to: determine a runout result of the tire based on the graph; and send the runout result to the terminal device 140 .

[0040] In some embodiments, the processor 123 is further configured to: determine a difference between a maximum distance and a minimum distance between the tire surface and the laser receiver 1212 based on the graph; and determine the runout result based on the difference and a preset threshold.

[0041] In some embodiments, the processor 123 is further configured to: control the rotation of the tire; continuously obtain the distance value between the tire surface and the laser receiver 1212 at preset time intervals; and generate the chart based on the distance value.

[0042] In some embodiments, the processor 123 is further configured to: receive an instruction to stop runout diagnosis from the terminal device 140 ; ​​control the laser emitter 1211 to stop emitting the laser beam; and send the tire runout result to the server 150 .

[0043] In some embodiments, the diagnostic device 120 may further include an interface 124. For example, the interface 124 may be a Type-C interface. The interface 124 may also be another type of interface (such as a Micro USB interface), which is not limited here.

[0044] In some embodiments, the interface 124 can be connected to the communication module 122. In some embodiments, the interface 124 is configured to communicate with the communication module 122.

[0045] In some embodiments, interface 124 is further configured to charge diagnostic device 120 .

[0046] In some embodiments, as Figure 3 As shown, the diagnostic device 120 may further include a battery 125 and a housing 126. The interface 124 charges the battery 125 in the diagnostic device 120, and the battery 125 supplies power to the sensor 121, the communication module 122 and / or the processor 123 in the diagnostic device 120.

[0047] The housing 126 is used to provide protection and support for the diagnostic device 120 . The sensor 121 , the communication module 122 and / or the processor 123 may be disposed within the housing 126 .

[0048] In some embodiments, as Figures 4A to 4C As shown, the diagnostic device 120 may further include a detection frame 127. In some embodiments, the tire is fixed to the detection frame 127; the laser emitter 1211 and the laser receiver 1212 are also fixed to the detection frame, so that the laser beam emitted by the laser emitter 1211 is perpendicular to the tire surface, and the laser receiver 1212 can receive the laser beam reflected from the tire surface.

[0049] In some embodiments, as Figures 4A to 4C As shown, the sensor 121, communication module 122, processor 123, and battery 125 in the diagnostic device 120 can be enclosed in a housing 126 and fixed to a detection frame 127, so that the laser light emitted by the laser emitter 1211 can be perpendicularly incident on the surface of the tire being diagnosed, and the laser receiver 1212 can receive the laser beam reflected from the tire surface.

For example, the diagnostic device 120 can receive a runout diagnostic instruction issued by the terminal device 140; in another example, the diagnostic device 120 can send the runout results to the server 150.

[0050] In some embodiments, as Figure 4C As shown, a laser beam hole 128 may be provided on the housing 126 , and the laser emitter 1211 may emit a laser beam through the laser beam hole 128 .

[0051] For detailed description of the functions of the modules of the tire runout diagnosis device 120 shown above, please refer to the relevant parts later in this specification, for example, Figure 5 and related instructions.

[0052] It should be noted that the above description of the tire runout diagnostic device 120 and its modules is for convenience of description only and does not limit this specification to the scope of the embodiments cited. It is understandable that for those skilled in the art, after understanding the principle of the system, it is possible to arbitrarily combine the modules or form a subsystem to connect with other modules without deviating from this principle. The modules in the tire runout diagnostic device 120 can be different modules in a system, or a module can realize the functions of two or more modules mentioned above. For example, the modules can share a storage module, or each module can have its own storage module. Such variations are all within the scope of protection of this specification.

[0053] Figure 5 FIG. 5 is an exemplary flow chart of a tire runout diagnosis method according to some embodiments of this specification. In some embodiments, process 500 may be executed by processor 123. Figure 5 As shown, process 500 includes the following steps.

[0054] Step 510: Receive a sway diagnosis instruction from a terminal device.

[0055] The runout diagnosis instruction is an instruction for diagnosing the runout of the tire. The runout diagnosis instruction can be input into the terminal device 140 by a user, and the processor 123 obtains it through the terminal device 140.

[0056] In some embodiments, the processor 123 may receive a yaw diagnostic instruction from the terminal device 140 via the communication module 122. For example, if the communication module includes a BLE module, the processor 123 may receive the yaw diagnostic instruction from the terminal device 140 via Bluetooth communication.

[0057] In some embodiments, the terminal device 140 may first send the yaw diagnosis instruction to the BLE module, and the processor 123 may receive the yaw diagnosis instruction from the BLE module via serial communication.

[0058] In some embodiments of the present specification, the processor 123 can simply and efficiently receive the deflection diagnosis instruction from the terminal device 140 through the BLE module and serial port communication, so that the communication process has low energy consumption and low cost.

[0059] Step 520: Based on the runout diagnosis instruction, control the laser transmitter to emit a laser beam perpendicular to the tire surface.

[0060] In some embodiments, after receiving the yaw diagnosis instruction, the processor 123 may control the laser emitter 1211 to emit a laser beam perpendicular to the tire surface of the two-wheeled vehicle based on the yaw diagnosis instruction.

[0061] Step 530: Control the laser receiver to receive the laser beam reflected from the tire surface.

[0062] In some embodiments, after controlling the laser transmitter 1211 to transmit a laser beam to the tire surface of the two-wheeled vehicle, the processor 123 may simultaneously control the laser receiver 1212 to receive the laser beam reflected from the tire surface.

[0063] In step 540 , a graph is generated based on the reflected laser beam to reflect the change in the distance between the tire surface and the laser receiver.

[0064] After the laser receiver 1212 receives the laser beam reflected from the tire surface, the processor 123 may generate a graph based on the received reflected laser beam. The graph may reflect changes in the distance between the tire surface and the laser receiver 1212. For example, the graph may be a curve graph, a bar graph, or the like, showing the distance values ​​between the tire surface and the laser receiver 1212 at multiple times during tire runout diagnosis.

[0065] In some embodiments, the processor 123 may control the tire to rotate; continuously obtain the distance value between the tire surface and the laser receiver at preset time intervals; and generate a graph based on the distance value.

[0066] Exemplarily, the processor 123 can control the rotation of the tire to be diagnosed for runout (for example, the tire can be rotated by powering on and unlocking the vehicle and turning the handle). When the tire rotates, the laser emitter 1211 continuously emits a laser beam toward the tire surface, and accordingly, the laser receiver 1212 continuously receives the laser beam reflected from the tire surface; the processor 123 can also continuously obtain the distance value between the tire surface and the laser receiver at preset time intervals (such as 50ms, 100ms, 200ms, 500ms, etc.) based on the reflected laser beam; and generate a chart based on the multiple distance values ​​continuously obtained.

[0067] The processor 123 may determine the distance between the tire surface and the laser receiver 1212 based on the time interval from the laser transmitter 1211 transmitting the laser beam to the laser receiver 1212 receiving the laser beam and the speed of light.

[0068] In some embodiments of the present specification, a visual chart can intuitively and accurately reflect the change in the distance between the tire surface and the laser receiver, which facilitates subsequent tire runout fault diagnosis.

[0069] Step 550: Send the chart to the terminal device and display the chart on the terminal device.

[0070] In some embodiments, after generating the chart, the processor 123 may send the chart to the terminal device 140 and display the chart on the terminal device 140 .

[0071] In some embodiments of the present specification, through communication between the terminal device 140 and the diagnostic device 120 (for example, the sensor 121, the communication module 122, the processor 123, etc. therein), the tire runout diagnosis process can be realized online and visualized, thereby more intuitively and readily determining whether the tire is running and the degree of the runout.

[0072] In some embodiments, the processor 123 may send the chart to the terminal device 140 through the communication module 122. For example, the processor 123 may send the chart to the terminal device 140 through a BLE module in a Bluetooth communication manner.

[0073] It is worth noting that to facilitate detection, the tire, laser emitter 1211, and laser receiver 1212 must be secured to detection frame 127 before tire runout fault diagnosis. In some embodiments, the user can secure the tire to detection frame 127 and secure laser emitter 1211 and laser receiver 1212 to detection frame 127, ensuring that the laser beam emitted by laser emitter 1211 is perpendicular to the tire surface and that laser receiver 1212 is able to receive the laser beam reflected from the tire surface.

[0074] In some embodiments of the present specification, the relative positions of the tire, the laser emitter 1211, and the laser receiver 1212 are fixed, which facilitates tire runout fault diagnosis and ensures the accuracy of the diagnosis results.

[0075] In some embodiments, processor 123 may also determine tire runout results based on the graph and send the runout results to terminal device 140. In some embodiments, processor 123 may not send the graph to terminal device 140, but instead directly send the runout results to terminal device 140 for display. In some embodiments, processor 123 may send both the graph and the runout results to terminal device 140 for display.

[0076] The runout result refers to the diagnosis result of the tire runout fault. The runout result can include whether the tire has runout and the runout amplitude.

[0077] The runout amplitude refers to the magnitude of the tire runout. The runout amplitude can be determined based on the difference between the maximum and minimum distances between the tire surface and the laser receiver. For example, the larger the difference, the larger the runout amplitude.

[0078] In some embodiments, the processor 123 can send the deflection result to the terminal device 140 through the communication module 122 and display it on the terminal device 140. In some embodiments, the deflection result can be displayed on the terminal device 140 in various ways, for example, through text, voice prompts, signal lights, etc.

[0079] In some embodiments, the processor 123 may determine the difference between the maximum distance and the minimum distance between the tire surface and the laser receiver based on a chart; and determine the runout result based on the difference and a preset threshold.

[0080] For example, when the graph is a curve graph, the processor 123 may determine the peaks and troughs of the curve graph as the maximum and minimum distances between the tire surface and the laser receiver 1212, respectively, and determine the difference between the peaks and troughs, i.e., the difference between the peaks and troughs. Furthermore, the processor 123 may compare the difference with a preset threshold. When the difference is greater than the preset threshold, the processor 123 determines that the runout result indicates tire runout and determines the difference as the tire runout amplitude. When the difference is less than or equal to the preset threshold, the processor 123 determines that the tire does not runout. In some embodiments, the preset threshold may be pre-set and stored in the storage device 160. For example, to accurately diagnose tire runout, the preset threshold may be within the range of 2 mm to 4 mm. For another example, to more accurately diagnose tire runout, the preset threshold may be 3 mm.

[0081] In some embodiments of the present specification, tire runout faults can be diagnosed intuitively and accurately through visual charts; in addition, through charts, compared with the method of relying on experience to diagnose runout faults, tire runout conditions can be diagnosed in a more intelligent, automated, and standardized manner; by setting a preset threshold, whether a tire is running can be accurately diagnosed.

[0082] In some embodiments, the processor 123 may also receive an instruction to stop runout diagnosis from the terminal device 140 ; ​​control the laser emitter 1211 to stop emitting the laser beam; and send the tire runout result to the server 150 .

[0083] In some embodiments, the instruction to stop the runout diagnosis can be obtained by user input. For example, after the tire runout fault diagnosis is completed, the user can input the instruction to stop the runout diagnosis to the terminal device 140, and the terminal device 140 sends the instruction to stop the runout diagnosis to the processor 123.

[0084] In some embodiments, the instruction to stop the runout diagnosis may also be automatically generated based on preset rules. The preset rules may include one or more of: the runout diagnosis duration is greater than a first threshold, the difference between the maximum and minimum distances between the tire surface and the laser receiver is greater than a preset threshold, etc.

[0085] In some embodiments of the present specification, automatically generating an instruction to stop runout diagnosis based on preset rules can make the tire runout diagnosis process more intelligent and automated, improve diagnostic efficiency, and save human resources.

[0086] In some embodiments, after the laser emitter 1211 stops emitting the laser beam, the communication module 122 (e.g., a Bluetooth module) in the tire runout diagnostic device 120 remains connected. At this time, the processor 123 uploads the diagnostic record to the server 150 via the communication module 122. The server 150 can construct and analyze data based on the diagnostic record to identify fault patterns and trends and predict future fault conditions, thereby providing data support for preventive maintenance.

[0087] In some embodiments, the processor 123 can send the tire runout results to the server 150 via a network or other means. In some embodiments of the present specification, sending the tire runout results obtained through diagnosis to the server can facilitate unified data processing and storage, achieve more efficient and accurate discovery of runout fault patterns and trends, predict future fault conditions, and thus provide data support for preventive maintenance.
