[0051] In order to make the technical problems to be solved, technical solutions and beneficial technical effects of the present application more clearly understood, the present application will be further described in detail below with reference to the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the protection scope of the present application.

[0052] Figure 1 A flowchart showing a method for predicting the wear degree of vehicle-mounted components according to an exemplary embodiment of the present application is shown. The following exemplary embodiments describe the method according to the present application in more detail.

[0053] As Figure 1 shown, the method may include steps S1 and S2. In step S1, during the operation of vehicle 1, status data of various vehicle-mounted components of vehicle 1 may be collected. In the current embodiment of the present application, image data about various vehicle-mounted components may be collected by in-vehicle camera 112, and sound data about various vehicle-mounted components may also be collected by in-vehicle microphone 111, where the vehicle-mounted components include, for example, chassis, tires, brake pads, shock absorbers, windshield wipers, suspensions, etc. As Figure 2Schematic diagram of an on-vehicle component layout according to an exemplary embodiment of the present application. In the wheel housing 14 of the vehicle 1, an on-vehicle microphone 111 may be arranged to collect sound data generated during the travel of the tires of the vehicle 1 on the road surface. Considering that sounds will be generated at multiple positions of the tire during its movement on the road surface, multiple on-vehicle microphones 111 may be installed in the wheel housing 14, and only two are shown herein by way of example; an on-vehicle camera 112 may be arranged in the wheel housing 14 of the vehicle 1, which is used to collect image data of each tire during the travel of the vehicle 1 on the road surface. An on-vehicle microphone 111 and / or an on-vehicle camera 112 may also be arranged at the chassis of the vehicle 1 for collecting image data and / or sound data of the chassis during the travel of the vehicle 1 on the road surface. In addition, the pressure information of each tire may be detected by a pressure sensor 113 arranged in the tire, considering that the probability of a tire blowout can be relatively accurately estimated based on the tire pressure information.

[0054] In step S2, the wear degree of the vehicle-mounted components of vehicle 1 can be estimated based on the collected status data and the reference status data regarding the fault conditions of various vehicle-mounted components. Among them, the reference status data can be optimized by using the vehicle maintenance data from the repair shop 3. In the sense of this application, the wear degree is used to characterize the wear degree and / or damage degree of vehicle-mounted components. For example, it is represented by a value between 0% and 100%. Among them, the larger the value of the wear degree of the vehicle-mounted component, the higher the wear degree of the vehicle-mounted component. As the wear degree accumulates, the vehicle-mounted component will gradually develop into a damaged state. In particular, when the value of the wear degree of the vehicle-mounted component exceeds the preset threshold, it can be considered that the vehicle-mounted component has a certain degree of damage. Moreover, the larger the value of the wear degree, the higher the damage degree of the vehicle-mounted component, and the higher the probability that the vehicle-mounted control function of the vehicle-mounted component fails. Among them, the failure of the vehicle-mounted control function means that the vehicle-mounted component can no longer effectively execute the vehicle-mounted control function it undertakes. In the local memory of vehicle 1, the reference status data regarding the fault conditions of various vehicle-mounted components can be stored. It can be understood as the vehicle-mounted component status parameters recorded when various types of faults occur in vehicle-mounted components under set standard test conditions. It can be used as an evaluation criterion for judging whether a vehicle-mounted component has a fault and the type of fault that occurs. It can be a data set obtained in the following way: Under a certain set operating condition of the vehicle, through a test device, the vehicle is made to have various types of vehicle-mounted component faults under the set standard test conditions. In this case, the status parameters of the vehicle-mounted component are recorded - including image data, sound data, and / or any other data that can characterize the current physical state of the vehicle-mounted component (such as temperature parameters, pressure parameters, etc.) - as the reference status data assigned to the corresponding type of vehicle-mounted component fault under this operating condition of the vehicle; Under the next set operating condition of the vehicle, through the test device, the vehicle is made to have various types of vehicle-mounted component faults under the set standard test conditions, and in this case, the status parameters of the vehicle-mounted component are recorded as the reference status data assigned to the corresponding type of vehicle-mounted component fault under the next operating condition of the vehicle, and so on. Thus, a data set of reference status data for various types of vehicle-mounted component faults under various operating conditions of the vehicle is collected and stored. Exemplarily, the reference status data can include image data and / or sound data regarding vehicle-mounted components recorded when various types of vehicle-mounted component faults occur under various vehicle operating conditions, and can also include tire pressure information when a tire of this model has a flat tire, etc.

[0055] Such as Figure 3The schematic diagram of the driving scenario shown can establish a communication connection with the repair workshop 3 through the in-vehicle communication unit 12 of the vehicle 1, and receive the repair data of vehicles of the same model as the vehicle 1 from the repair workshop 3 under authorized circumstances. In the control unit 13 of the vehicle 1, these vehicle repair data can be used to perform a credibility test on the reference state data, and the reference state data that fails the credibility test can be deleted. These vehicle repair data can also be used to correct the fault conditions of the in-vehicle components assigned to the reference state data, thereby realizing the optimization processing of the reference state data and improving the accuracy of the reference state data. By comparing the collected state data with the reference state data regarding the fault conditions of various in-vehicle components, the wear degree of the in-vehicle components of the vehicle 1 can be estimated, and the comparison can be performed by means of a machine learning model trained with a large amount of reference state data.

[0056] The reference state data can also be stored in the cloud server 2, and the required reference state data can be downloaded from the cloud server 2 when performing the comparison. As Figure 4 shown in the working flowchart of the method for estimating the wear degree of in-vehicle components according to another exemplary embodiment of the present application, the method may further include step S11. In step S11, a request message for the reference state data regarding the fault conditions of various in-vehicle components can be sent to the cloud server 2, and the requested reference state data can be received from the cloud server 2. Here, reference state data related to the current operating condition of the vehicle can be requested from the cloud server 2, and the wear degree of the in-vehicle components of the vehicle 1 can be estimated by comparing the state data and the reference state data under the same vehicle operating condition.

[0057] According to the embodiment of the present application, the vehicle repair data is fully utilized to optimize the reference state data regarding the fault conditions of various in-vehicle components. By comparing the collected state data of the vehicle components with the optimized reference state data, the wear degree of the in-vehicle components can be estimated. Thus, the wear degree of the in-vehicle components can be determined in a manner with low technical overhead and relatively high accuracy, laying a foundation for timely detecting severely worn in-vehicle components and formulating a repair plan, and avoiding vehicle control function failures caused by severely worn in-vehicle components, such as brake function failure, steering function failure, shift function failure, etc., and traffic accidents caused by vehicle control function failures.

[0058] Figure 5 shown in the working flowchart of the method for estimating the wear degree of in-vehicle components according to another exemplary embodiment of the present application. Only the differences from the Figure 1 embodiment shown will be described below, and the same steps will not be repeated for the sake of brevity.

[0059] As Figure 5As shown, the method may further include step S3. In step S3, when the predicted wear degree of the vehicle-mounted component is higher than a pre-given wear degree threshold, notification information about the wear degree of the vehicle-mounted component and / or notification information about a maintenance plan planned based on the wear degree of the vehicle-mounted component may be sent to the user of vehicle 1. In the case where safety-critical vehicle-mounted components such as brake pads and tires are severely worn, it may cause serious failure of vehicle control functions and even traffic accidents. Therefore, it is necessary to timely notify the user to repair the corresponding vehicle-mounted components, avoiding vehicle control function failure caused by severely worn vehicle-mounted components and traffic accidents caused by vehicle control function failure. In addition, a maintenance plan for the corresponding vehicle components by the repair workshop that the user often goes to may be planned based on the wear degree of the vehicle-mounted component, and the determined maintenance plan may be notified to the user, saving the user the cumbersome process of querying the maintenance plan. Here, acoustic notification information may be sent to the user through a vehicle-mounted voice device, and optical notification information may also be sent to the user through a central control display screen, a head-up display, and / or an instrument panel, etc.

[0060] Figure 6 FIG. shows a flowchart of a method for predicting the wear degree of vehicle-mounted components according to another exemplary embodiment of the present application. Only the differences from the embodiment shown in Figure 1 will be described below, and the same steps will not be repeated for the sake of brevity.

[0061] As Figure 6 shown, the method may further include step S4. In step S4, reference status data about the failure conditions of various vehicle-mounted components after optimization processing may be sent to cloud server 2. These reference status data may be forwarded by cloud server 2 to other vehicles 4, so that other vehicles 4 can also use these reference status data to predict the wear degree of their vehicle-mounted components.

[0062] Figure 7 FIG. shows a flowchart of a method for predicting the wear degree of vehicle-mounted components according to another exemplary embodiment of the present application. Only the differences from the embodiment shown in Figure 1 will be described below, and the same steps will not be repeated for the sake of brevity.

[0063] As Figure 7 shown, the method may further include step S5. In step S5, the status data of each vehicle-mounted component of vehicle 1 collected may be sent to cloud server 2, especially the status data of safety-critical vehicle-mounted components such as brake pads and tires, for example, including the sound information of brake pads, tire pressure information, etc. In cloud server 2, the collected status data may be monitored in real time and the collected status data may be analyzed, such as accident analysis, fault analysis, etc.

[0064] Figure 8 FIG. 1 shows a schematic block diagram of a device 10 for predicting the wear degree of vehicle components according to an exemplary embodiment of the present application.

[0065] As Figure 8 shown, the device 10 configured in the vehicle 1 may include the following components:

[0066] - A status data acquisition unit 11, which is configured to acquire the status data of various vehicle components during the operation of the vehicle 1. For example, it includes an in-vehicle camera 112, an in-vehicle microphone 111, and / or a pressure sensor 113 arranged in the tire, etc. These sensors can send the acquired status data to the control unit 13;

[0067] - An in-vehicle communication unit 12, which is configured to receive vehicle maintenance data from the repair shop 3; and

[0068] - A control unit 13, which is used to execute the method for predicting the wear degree of vehicle components according to the present application.

[0069] Optionally, the in-vehicle communication unit 12 may also be configured to send a request message for reference status data regarding various vehicle component failure conditions to the cloud server 2 and receive the requested reference status data from the cloud server 2.

[0070] Optionally, the in-vehicle communication unit 12 may also be configured to send the status data of various vehicle components of the vehicle 1 acquired, and / or the optimized reference status data regarding various vehicle component failure conditions.

[0071] In addition, the device 10 may further include a notification unit 14, which is configured to send notification information regarding the wear degree of the vehicle components to the user of the vehicle 1, and / or send notification information regarding the maintenance plan planned based on the wear degree of the vehicle components. The notification unit 14 includes, for example, an in-vehicle voice device, a central control display screen, a head-up display, and / or an instrument panel, etc.

[0072] The method for predicting the wear degree of vehicle components executed in the vehicle 1 is described above. Next, the method for receiving and sending reference status data regarding vehicle component failure conditions executed in the cloud server 2 is described.

[0073] Figure 9 FIG. 2 shows a working flowchart of a method for receiving and sending status data of vehicle components according to another exemplary embodiment of the present application. As Figure 9As shown, the method may include steps S1' and S2'. In step S1', reference status data regarding various in-vehicle component failure conditions optimized by the method for predicting the wear degree of in-vehicle components according to the present application is received from vehicle 1. The received reference status data may be fused with the reference status data already stored in cloud server 2 to form a new reference status data set. In particular, the corresponding data in the stored reference status data may be replaced with the reference status data that has passed the credibility test and / or the corrected reference status data, and the data content newly added by the received reference status data relative to the stored reference status data may also be added to the fused reference status data set.

[0074] In step S2', in response to a request message for reference status data regarding various in-vehicle component failure conditions of other vehicle 4, the requested reference status data may be sent to the other vehicle 4. After receiving the requested reference status data through its in-vehicle communication unit 41, other vehicle 4 may estimate the wear degree of the in-vehicle components of other vehicle 4 based on the status data of the in-vehicle components of other vehicle 4 collected and the reference status data. Since these reference status data have been optimized, the prediction accuracy of other vehicle 4 for the wear degree of in-vehicle components can be improved accordingly.

[0075] Figure 10 The working flowchart of a method for receiving and transmitting status data of vehicle components according to another exemplary embodiment of the present application is shown. Only the differences from the embodiment shown in Figure 9 will be described below, and the same steps will not be repeated for the sake of brevity.

[0076] As Figure 10 shown, the method may further include step S3'. In step S3', a request message for reference status data regarding various in-vehicle component failure conditions may be received from vehicle 1, and the requested reference status data may be sent to vehicle 1. In this embodiment, no reference status data is stored in the local memory of vehicle 1, so it is necessary to request reference status data related to the current operating conditions of the vehicle from cloud server 2, and cloud server 2 sends the requested reference status data to vehicle 1 after receiving the request message.

[0077] Figure 11 The working flowchart of a method for receiving and transmitting status data of vehicle components according to another exemplary embodiment of the present application is shown. Only the differences from the embodiment shown in Figure 9 will be described below, and the same steps will not be repeated for the sake of brevity.

[0078] As Figure 11As shown, the method may further include step S4'. In step S4', status data of various in-vehicle components of vehicle 1 collected during the driving of vehicle 1 can be received, especially status data of safety-critical in-vehicle components such as brake pads and tires, for example, including sound information of brake pads, tire pressure information, etc. The collected status data can be monitored in real time and analyzed in cloud server 2, such as accident analysis, fault analysis, etc.

[0079] In addition, it should be noted that the step numbers described herein do not necessarily represent the order of precedence, but are merely a kind of reference numeral, and according to specific circumstances, the order can be changed as long as the technical purpose of the present application can be achieved.
