[0038] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0039] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The singular forms of "a", "said" and "the" used in this application and the appended claims are also intended to include plural forms unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0040] It should be noted that the information and data involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards of relevant countries and regions.

[0041] First, a brief introduction is given to the terms involved in the embodiments of this application:

[0042] Head-Up Display (HUD): A device with projection function, mainly used to project vehicle operation information onto the front windshield of the car through optical projection technology. For example, vehicle speed, rotation speed, navigation prompts, warning information of the driving assistance system, etc.

[0043] In this embodiment, the vehicle-mounted display device is a HUD device as an example for explanation, and the projection medium refers to the front windshield of the first vehicle. The HUD device projects the three-dimensional fault model onto the front windshield, and the driver can maintain a driving posture during driving and obtain the vehicle fault status without looking down at the instrument panel. This can reduce the time the driver's eyes are away from the road and improve driving safety.

[0044] Cars are an important means of transportation. As they are used for a long time and the mileage accumulates, the various parts of the vehicle gradually wear out, and failures are inevitable.

[0045] The related technology mainly relies on the fault display mechanism of the instrument panel to convey vehicle fault information to the driver. When a system or component of the vehicle fails / abnormally, the instrument panel will quickly light up the corresponding fault icon. For example, if the faulty component is the engine, when the engine's crankshaft, piston, spark plug and other related components suddenly have problems, the icon representing the engine in the instrument panel will immediately light up a striking yellow warning light.

[0046] However, the above fault prompt method has limitations. Although the fault icon can remind the occupants of the specific parts of the vehicle that have failed, the occupants cannot quickly locate the specific location of the faulty parts in the vehicle based on the icon. For the occupants with weak vehicle technical knowledge, it is difficult to determine the type of fault and the severity of the fault, and it is impossible to quickly obtain a solution and handle / repair the faulty parts in time, resulting in safety hazards when using the vehicle.

[0047] The present application provides a vehicle-based fault prompt method. In the case of a vehicle component failure, a three-dimensional vehicle model is obtained by three-dimensionally modeling the entire vehicle. By collecting vehicle operation information, the faulty component in the vehicle is determined, and the model part corresponding to the faulty component is rendered in a prominent form in the three-dimensional vehicle model to obtain a three-dimensional fault model. The three-dimensional fault model is projected onto the front windshield of the vehicle through the HUD device to intuitively display the vehicle fault situation, so that the driver can quickly locate the position of the faulty component relative to the entire vehicle. The information is displayed in a projection manner using the HUD device, so that the driver can still maintain the driving posture even when the vehicle is driving, and driving safety is ensured while prompting the user of the vehicle fault situation. In some embodiments, after obtaining the vehicle operation information and performing fault analysis, in addition to rendering the three-dimensional model of the faulty component, the corresponding fault handling prompt information will be generated based on the fault type, and projected and displayed around the three-dimensional fault model to guide the driver on how to repair / handle the faulty component and provide a solution. Compared with the method of using dashboard icons to display in related technologies, this solution can allow drivers to understand vehicle fault information more clearly and provide targeted solutions, so that drivers have the ability to respond and handle sudden vehicle failures in a timely manner, thereby improving vehicle safety.

[0048] Next, the vehicle-based fault prompt system involved in the embodiment of the present application is described. For illustration, please refer to Figure 1 The vehicle-based fault warning system involves a vehicle component sensor 110, a vehicle control unit 120, a central control component 130, a vehicle display device 140, a vehicle display control unit 141, and a projection medium 150 of a first vehicle.

[0049] The vehicle component sensor 110 is used to collect vehicle operation information of the first vehicle, and the vehicle operation information is used to indicate the operation status of each component of the first vehicle. The vehicle component sensor 110 sends the collected vehicle operation information to the vehicle control unit 120, and the vehicle control unit 120 analyzes the vehicle operation information to determine whether there is a fault in the component of the first vehicle. If there is a faulty component, the vehicle operation information is sent to the vehicle display control unit 141.

[0050] The vehicle display control unit 141 includes a pre-established three-dimensional vehicle model, which is a model obtained by three-dimensionally modeling the first vehicle, that is, each component and the vehicle frame of the first vehicle are modeled separately and then assembled to obtain the three-dimensional vehicle model.

[0051] The vehicle display control unit 141 renders the model portion corresponding to the faulty component in the three-dimensional vehicle model according to the faulty component indicated by the vehicle operation information to obtain a three-dimensional fault model. For example, the three-dimensional vehicle model is gray, the faulty component indicated by the vehicle operation information is the first component, the model portion of the first component in the three-dimensional vehicle model is rendered red, and the other components in the three-dimensional vehicle model except the first component remain gray to obtain a three-dimensional fault model.

[0052] The rendered three-dimensional fault model is displayed through the vehicle display device 140 to prompt the occupants of the vehicle of the type of fault that occurred in the first vehicle. For example, the vehicle display device 140 includes a display screen, and the three-dimensional fault model is directly displayed through the display screen.

[0053] In some embodiments, when rendering the model, the vehicle display control unit 141 obtains fault handling prompt information corresponding to the faulty component according to the vehicle operation information, and the fault handling prompt information is used to guide the occupants on how to handle the faulty component to improve the safety during driving. The vehicle display device 140 displays the fault handling prompt information while displaying the three-dimensional fault model, and can combine the fault type with the fault handling solution to prompt the occupants.

[0054] In some embodiments, the vehicle display device 140 is a HUD device, which can project the three-dimensional fault model and fault handling prompt information onto the projection medium 150, and the projection medium 150 is the front windshield of the vehicle. By projecting the three-dimensional fault model and fault handling prompt information by the HUD device, the user can maintain the driving posture when viewing the fault information during driving, avoiding the safety hazard caused by the user's distracted driving.

[0055] Among them, the central control component 130 is used to control the vehicle display control unit 141, and the vehicle occupants can turn on or off the vehicle display control unit 141 through the central control component 130. When the vehicle display control unit 141 is turned on, the fault information display process shown above will be realized. When the vehicle display control unit 141 is turned off, the vehicle fault situation is prompted by other means.

[0056] Combined with the above-mentioned noun introduction and application scenarios, the vehicle-based fault prompt method provided by the present application is described, taking the method executed by the vehicle terminal as an example. Figure 2 As shown, Figure 2 The flowchart of a vehicle-based fault prompt method provided by an exemplary embodiment of the present application includes the following steps.

[0057] Step 210, collecting vehicle operation information.

[0058] The vehicle operation information is used to indicate the operation status of each component of the first vehicle. The first vehicle is equipped with a variety of sensors, which are respectively used to collect the operation information of different vehicle components.

[0059] Optionally, the vehicle operation information includes operation information of at least one of the following components.

[0060] 1. Power system operation information; the power system includes the following components: engine / motor.

[0061] For example, when the first vehicle is a fuel vehicle, the vehicle operation information includes engine operation information, such as engine speed, engine temperature, engine output torque, engine exhaust conditions, engine fuel supply conditions, etc.

[0062] For example, when the first vehicle is a new energy vehicle, the vehicle operation information includes motor operation information, such as motor torque, motor temperature, etc.

[0063] 2. Chassis system operation information; the chassis system includes the following components: tires, frame, suspension components, etc.

[0064] For example, the operating information of the chassis system includes information such as tire pressure, tire temperature, and tire speed of each tire of the first vehicle.

[0065] 3. Operation information of the lighting system; the lighting system includes external lights and internal lights, among which the external lights include turn signals, brake lights, headlights, fog lights, etc.

[0066] For example, the operating information of the lighting system includes the on-state (whether it can be turned on), brightness, etc. of these lights.

[0067] 4. Braking system operation information; the braking system includes the following components: brake pedal, brake pads, brake disc, brake hydraulic device, etc.

[0068] For example, the operation information of the brake system includes the thickness of the brake pad of the first vehicle, the output brake pressure, the resistance when the brake pedal is stepped on, etc.

[0069] Step 220 , in response to the vehicle operation information indicating that a first component in the first vehicle is faulty, obtaining a three-dimensional vehicle model.

[0070] The three-dimensional vehicle model is a model obtained by three-dimensionally modeling the first vehicle. The three-dimensional vehicle model has the same appearance and structure as the first vehicle. The three-dimensional vehicle model is a model obtained by scaling the first vehicle in proportion.

[0071] A three-dimensional vehicle model is pre-stored in the on-board display control unit of the first vehicle. When the vehicle operation information indicates that there is a vehicle fault, obtaining the three-dimensional vehicle model can display the faulty component in three-dimensional form, assisting the user to quickly locate the position of the faulty component relative to the entire vehicle.

[0072] Exemplarily, components of the first vehicle are modeled separately to obtain model parts corresponding to each component, which are assembled to obtain a three-dimensional vehicle model of the first vehicle.

[0073] Optionally, operation reference information is obtained, where the operation reference information is used to indicate the operating state of each component of the first vehicle when it meets a preset stability condition, and the preset stability condition refers to the state maintained by each component when the first vehicle can operate stably.

[0074] A comparative analysis result is determined based on a difference between the vehicle operation information and the operation reference information.

[0075] In some embodiments, according to different operating conditions of the first vehicle, operating reference information is configured for each operating condition.

[0076] For example, the operating reference information includes first operating reference information when the first vehicle is in a driving state and second operating reference information when the first vehicle is in a dormant state. When judging whether there is a component failure in the first vehicle based on the vehicle operating information, the corresponding operating reference information can be obtained according to the current operating state of the first vehicle to improve the accuracy of the comparative analysis results.

[0077] In response to the comparison and analysis result indicating that the first component does not meet the preset stability condition, it is determined that the first component is faulty, and a three-dimensional vehicle model is acquired.

[0078] Exemplarily, the vehicle operation information and the operation reference information are divided according to component types, and are compared separately to obtain a comparison result corresponding to each component, and the comparison results corresponding to all components are integrated to obtain a complete comparison analysis result.

[0079] Here, the i-th component is taken as an example for explanation, the operation reference information includes the i-th reference information of the i-th component, and the vehicle operation information includes the i-th operation information of the i-th component. Based on the i-th reference information and the i-th operation information, a comparative analysis is performed to obtain the i-th comparison result corresponding to the i-th component. i is a positive integer.

[0080] The preset stability condition includes the stability condition of the i-th component.

[0081] When the i-th comparison result does not meet the stability condition of the i-th component, it is determined that the i-th component has a fault.

[0082] Exemplarily, the first component does not meet the preset stability condition means that the first operating information related to the first component in the vehicle operating information and the first reference information related to the first component in the operating reference information do not match. For example, the difference between the first operating information and the first reference information exceeds a first difference threshold. Alternatively, the first operating information does not meet the range indicated by the first reference information.

[0083] Exemplarily, the first component refers to the headlight of the first vehicle, the first operating information includes the current brightness level and actual brightness of the headlight, and the first reference information includes the correspondence between the brightness level and theoretical brightness of the headlight.

[0084] Determine whether there is a headlight fault based on the relationship between the theoretical brightness and the actual brightness corresponding to the current brightness gear; if the brightness difference between the theoretical brightness and the actual brightness exceeds the first difference threshold, then there is a headlight fault; if the brightness difference between the theoretical brightness and the actual brightness does not exceed the first difference threshold, then there is no headlight fault.

[0085] Exemplarily, the first component is an engine, the first operating information includes a current operating temperature of the engine, and the first reference information includes a temperature range of the engine when the first vehicle operates stably.

[0086] Determine whether the engine is faulty based on the relationship between the current operating temperature and the temperature range; if the current operating temperature is within the temperature range, the engine is not faulty; if the current operating temperature is not within the temperature range, the engine is faulty.

[0087] Step 230 , rendering the three-dimensional vehicle model based on the vehicle operation information to obtain a three-dimensional fault model.

[0088] The three-dimensional fault model includes a model portion corresponding to the first component displayed in a highlighted form, that is, the representation form of the component portion model with faults in the three-dimensional fault model is different from the representation form of the component portion model without faults.

[0089] By highlighting the model portion corresponding to the first component, it is possible to distinguish between faulty components and non-faulty components, intuitively reminding occupants of the type of faulty components in the first vehicle and quickly locating the position of the faulty components in the first vehicle.

[0090] Optionally, first reference information corresponding to the first component is obtained, and a first fault type of the first component is determined based on the vehicle operation information and the first reference information.

[0091] The first reference information is used to indicate a corresponding relationship between an operating state of the first component and at least two fault types.

[0092] Exemplarily, the at least two failure types include functional failure, performance degradation failure, component life failure, compatibility failure, etc.

[0093] Among them, functional failure refers to the inability of the first component to realize the component function / functional failure during operation, including complete failure and partial failure, corresponding to different severity levels.

[0094] A performance degradation fault means that the effect of the first component when operating to achieve the component function is lower than the calibrated effect, for example, the current unit power output of the engine is much lower than the average power output.

[0095] Component life failure means that the total usage time of the first component exceeds the service life and needs to be replaced.

[0096] Compatibility failure refers to incompatibility between the first component and the first vehicle, and the first component cannot realize the component function inside the first vehicle.

[0097] Optionally, a model portion corresponding to the first component is indexed in the three-dimensional vehicle model based on the vehicle operation information.

[0098] A target manner for rendering the three-dimensional vehicle model is obtained based on the first fault type.

[0099] Exemplarily, different rendering modes correspond to different fault types, and the fault types include functional faults, performance degradation faults, component life faults, and compatibility faults, which correspond to the first rendering mode, the second rendering mode, the third rendering mode, and the fourth rendering mode, respectively. The difference between the different rendering modes lies in at least one of the rendered color, pattern, and brightness.

[0100] For example, the first rendering mode, the second rendering mode, the third rendering mode and the fourth rendering mode correspond to four different colors respectively. Based on the first fault type, one of the above rendering modes is selected as a target mode for rendering the three-dimensional vehicle model.

[0101] The model portion corresponding to the first component in the three-dimensional vehicle model is rendered based on a target method to obtain a three-dimensional fault model, wherein the model portion other than the first component in the rendered three-dimensional fault model has a different expression form from the model portion corresponding to the first component.

[0102] In some embodiments, at least two types of faults occur simultaneously in a vehicle component, priorities are set for the above fault types, and a rendering method is determined based on the priorities of the fault types.

[0103] Exemplarily, the above-mentioned fault types are ranked from high to low in terms of priority: functional fault>compatibility fault>performance degradation fault>component life fault.

[0104] When there are at least two fault types, the rendering methods include the following: (1) Allocating rendering areas to different fault types according to priority, where the rendering area corresponding to the fault type with a higher priority is larger than that of the fault type with a lower priority; for example, if the first component has a functional fault and a component life fault, two-thirds of the area of ​​the first component is rendered in the first rendering method, and the remaining one-third of the area is rendered in the fourth rendering method. (2) Rendering is performed in the rendering method corresponding to the fault type with the highest priority; for example, if the first component has a functional fault and a component life fault, it is rendered in the first rendering method corresponding to the functional fault.

[0105] It is worth noting that, for the rendering methods corresponding to different fault types, no matter which rendering method is used to render the model part of the faulty component in the three-dimensional vehicle model, the expression form of the model part of the faulty component in the obtained three-dimensional fault model is different from the expression form of the model part of other components.

[0106] For example, the first rendering mode, the second rendering mode, the third rendering mode, and the fourth rendering mode correspond to red, blue, green, and yellow, respectively. The surface of the three-dimensional vehicle model is gray, and the target mode for rendering the first component is the first rendering mode. Then, in the three-dimensional fault model obtained after rendering, the model part corresponding to the first component is red, and the model parts corresponding to other components are black.

[0107] In some embodiments, for the model parts of other components except the first component in the three-dimensional vehicle operation information model, other rendering methods different from the target method can be used for rendering; or only the first component model part can be rendered, and the other component model parts remain unrendered, that is, the same as the expression form of other component models in the three-dimensional vehicle model.

[0108] For example, the surface of the three-dimensional vehicle model is gray. In the three-dimensional fault model obtained after rendering, the model portion corresponding to the first component is red, and the model portions corresponding to other components are still gray.

[0109] Step 240, obtaining corresponding fault handling prompt information based on the vehicle operation information.

[0110] The fault handling prompt information is used to indicate the way to handle the first component. For the vehicle personnel who have little knowledge of vehicles, the fault handling prompt information can directly guide them on the way to handle the first vehicle.

[0111] The fault handling prompt information includes at least one of the following elements: (1) a text element, such as a paragraph of instructions, indicating how to handle the faulty component or how to obtain maintenance services;

[0112] (2) Digital elements, such as a target range in which the relevant parameters of the faulty component need to be maintained in numerical form; (3) Animation elements, such as an instructional animation that demonstrates how to manually repair a faulty component; (4) Audio elements, such as a warning audio that reminds the occupants of the vehicle to promptly replace / repair the faulty component or to stop using the vehicle; (5) Graphic elements, such as an instructional picture of how to repair a faulty component, which contains illustrative operating steps.

[0113] For example, the first component is the engine, and its fault type is a compatibility fault. The fault handling prompt information prompts the occupants in the vehicle to replace the first component in text form: "The engine model is A, which is incompatible with the vehicle. Please replace it with model B. The address of the nearby service station is as follows: a certain street repair shop."

[0114] Among them, the fault handling prompt information recommends the address of at least one service station to the user, and the service station to be recommended can be determined by at least one of the following methods: (1) Sorting based on the distance between the location of the first vehicle and the candidate service stations, and obtaining the address of at least one service station closest to the first vehicle; (2) Based on the fault type of the first component, the address of a service station that can provide repair / replacement service for the first component is obtained. For example, if the first component needs to be replaced, the address of a service station whose first component inventory can meet the first vehicle's demand for replacing the first component is obtained; (3) Analyzing the cruising range of the first vehicle based on the fault condition of the first component, determining the address of the service station based on the cruising range, and ensuring that the cruising range of the first vehicle can support its travel to the service station.

[0115] Optionally, at least two candidate processing solutions are obtained, and the at least two candidate processing solutions are used to guide the maintenance of the first vehicle components. A target processing solution is obtained from the at least two candidate processing solutions based on the first fault type of the first component. Fault processing prompt information is generated based on the target processing solution.

[0116] Determining the fault type of a faulty component is conducive to obtaining accurate and efficient solutions, improving the accuracy of fault handling prompt information, helping vehicle crew members to promptly handle problems caused by faulty components, and resolving safety hazards during vehicle driving.

[0117] Step 250: Display the three-dimensional fault model and fault handling prompt information through the on-board display device of the first vehicle.

[0118] Optionally, the vehicle-mounted display device has a projection function. The three-dimensional fault model and the fault handling prompt information are projected onto a projection medium of the first vehicle through the vehicle-mounted display device for display, and the projection medium is used to display the content projected by the vehicle-mounted display device.

[0119] For example, the vehicle display device is a HUD device and the projection medium is a front windshield. The HUD device projects a three-dimensional fault model and fault handling prompt information onto the front windshield, and the user can look up to view the above information on the front windshield to understand the vehicle fault situation.

[0120] The HUD device includes a HUD control unit and a HUD optical machine. The HUD control unit stores a three-dimensional fault model and fault handling prompt information. The HUD control unit is used to control the HUD optical machine to project the three-dimensional fault model and fault handling prompt information onto the front windshield of the vehicle, so that the human eye can see the images corresponding to the three-dimensional fault model and fault handling prompt information through light reflection.

[0121] Exemplarily, dimension data of the first component is acquired, where the dimension data is used to indicate a relative ratio between a dimension of the first component and a dimension of the first vehicle.

[0122] Since the three-dimensional vehicle model is a model obtained by scaling the first vehicle in proportion, the size data of the first component can also indicate the relative ratio between the size of the model portion of the first component and the size of the three-dimensional vehicle model.

[0123] The projection display area is determined based on the size data, and the projection display area is used to indicate the area occupied by the three-dimensional fault model in the projection medium.

[0124] Exemplarily, a preset projection area requirement is obtained, and the projection area requirement is used to indicate the fault projection area of ​​the faulty component. Based on the relative relationship between the fault projection area and the dimension data, the projection display area of ​​the three-dimensional fault model can be determined.

[0125] The above projection area determination process can ensure that the projection area of ​​the faulty component in the projection medium meets certain requirements, so that the occupants can clearly see the specific location of the faulty component, thereby avoiding the situation where the user fails to notice the faulty component or misjudges the type of the faulty component due to the faulty component being too small.

[0126] The vehicle operation information is analyzed to obtain a fault analysis result of the first component, and the fault analysis result is used to characterize the fault degree of the first component, that is, to characterize the severity of the fault of the first component, so as to determine whether to replace or repair the first component.

[0127] A first representation form of the fault handling prompt information is determined based on the fault analysis result, and the first representation form includes at least one of color, size, and shape when displaying the fault handling prompt information.

[0128] The three-dimensional fault model is displayed in the projection medium based on the projection display area by the vehicle-mounted display device. And the fault handling prompt information is displayed in the projection medium based on the first representation form by the vehicle-mounted display device.

[0129] Optionally, energy remaining data of the first vehicle is obtained, the energy remaining data is used to indicate the remaining amount of energy for providing power for the operation of the first vehicle. The duration is obtained based on the energy remaining data. The three-dimensional fault model and fault handling prompt information are displayed based on the duration.

[0130] In response to the energy reserve data being lower than a preset reserve threshold, the three-dimensional fault model is cancelled from being displayed.

[0131] For example, when the first vehicle is a fuel vehicle, the energy remaining data is the oil storage capacity of the first vehicle, and when the first vehicle is an electric / new energy vehicle, the energy remaining data is the battery power of the first vehicle. The energy remaining data can indicate the ability of the first vehicle to maintain the running state and the endurance time, etc. When prompting the occupants with fault information, the corresponding duration is obtained based on the energy remaining data, which can ensure that the occupants have sufficient time to obtain the fault information while reducing the energy consumption caused by displaying the above information.

[0132] Optionally, the vehicle operation information is collected and updated in real time to obtain updated vehicle operation information.

[0133] In response to the updated vehicle operation information indicating that there is no fault in each component of the first vehicle, the display of the three-dimensional fault model and the fault handling prompt information is cancelled.

[0134] In some embodiments, after the vehicle occupants actively process the first component based on the fault handling prompt information, the first component can be restored to a stable operating state, the vehicle operation information can be updated in real time, and the display mode of the fault information can be determined in a timely manner, which can save vehicle energy and avoid visual interference to the vehicle occupants caused by the continuous display of the fault information. In addition, when there are errors or abnormalities in the fault handling prompt information or the vehicle operation information, the fault handling prompt information can also be updated by updating the vehicle operation information in real time, avoiding misleading the vehicle occupants due to the long display time of the error information caused by the vehicle system misjudgment or analysis error.

[0135] In some embodiments, taking into account the sitting height and line of sight of the occupants of the vehicle, when displaying the three-dimensional fault model and fault handling prompt information through the vehicle-mounted display device, the information display position can be adjusted so that the occupants of the vehicle can immediately observe the fault information.

[0136] Optionally, an interior environment image of the first vehicle is collected, and the interior environment image indicates that the first subject is in the first vehicle.

[0137] The first vehicle is installed with an in-vehicle camera assembly, which can capture images of the vehicle's internal environment, wherein the in-vehicle camera assembly performs image capture when authorized and turned on by the occupants of the vehicle.

[0138] The first subject refers to at least one of a passenger riding in the first vehicle and a driver driving the first vehicle. Exemplarily, the first subject is the driver sitting in the driving seat.

[0139] The in-vehicle environment image is analyzed to obtain the sight line height information of the first subject, where the sight line height information is used to indicate the sight line height of the first subject.

[0140] Exemplarily, after collecting the in-vehicle environment image, the height of the subject's eyes is determined based on the relative position of the first subject and the seat to obtain the height information.

[0141] The information display area is determined based on the sight height information, and the information display area matches the sight height information. The information display area is any part within the complete display area of ​​the vehicle-mounted display device.

[0142] Exemplarily, the sight height indicated in the sight height information matches the display area of ​​the first component with the fault. After obtaining the sight height information, the first display area of ​​the first component with the fault is determined based on the sight height. The three-dimensional vehicle model can reflect the relative position relationship between the first component and the first vehicle. The display area of ​​the three-dimensional vehicle model is determined based on the first display area and the above relative position relationship to obtain the information display area.

[0143] For example, taking the vehicle-mounted display device as a HUD device and the information display area as the front windshield (projection medium) as an example, the information display area is any area on the front windshield.

[0144] The matching of the information display area and the line of sight height information means that when the first subject maintains the current posture, the line of sight can directly observe the three-dimensional fault model and the fault handling prompt information.

[0145] After obtaining the sight height information, the display position of the first component on the front windshield of the vehicle is determined based on the sight point corresponding to the sight height, and the information display area for displaying the three-dimensional fault model is further determined. It is ensured that when the first subject maintains the current posture, the position of the first component with the fault is immediately determined through the three-dimensional fault model.

[0146] The three-dimensional fault model and fault handling prompt information are displayed in the information display area through the on-board display device of the first vehicle.

[0147] In summary, the vehicle-based fault prompt method provided by the present application determines the faulty components in the vehicle by collecting vehicle operation information, performs three-dimensional modeling on the entire vehicle, and renders the part of the three-dimensional model where the faulty components are located in a prominent form, which can intuitively display the vehicle fault situation, quickly and accurately locate the vehicle fault location, improve the efficiency of the crew in obtaining vehicle fault information, and save time. The fault handling prompt information is displayed while displaying the three-dimensional fault model, and the information during the fault handling is used to provide guidance for the crew's subsequent driving, maintenance, and other processing, thereby improving maintenance efficiency, so that the vehicle fault situation can be resolved in a timely manner, and improving vehicle safety.
