Description

Technical Field

[0001] This application relates to the field of vehicle health management technology, and in particular to a method for assessing vehicle health status, a vehicle, and related devices. Background Technology

[0002] With advancements in automotive manufacturing technology and evolving user needs, vehicles are becoming increasingly intelligent, featuring in-car voice robots and smart interactive screens. Vehicle design philosophies are also gradually aligning with user requirements. While current vehicles demonstrate significant progress in intelligence compared to traditional vehicles, a gap still exists between current technology and user needs. Specifically, existing methods for assessing vehicle health typically involve manual, step-by-step inspections, which are not only time-consuming and labor-intensive but also prone to over-maintenance and delays in detecting malfunctions. Summary of the Invention

[0003] In view of the above problems, this application provides a vehicle health status assessment method, a vehicle, and related devices to achieve automatic assessment of vehicle health status, effectively avoid over-maintenance, and promptly detect vehicle malfunctions. The specific solution is as follows:

[0004] A method for assessing vehicle health status, comprising:

[0005] Obtain a request instruction to perform a health status assessment on the vehicle, the request instruction carrying a vehicle identification identifier;

[0006] In response to the request instruction, at least one component of the vehicle is identified;

[0007] The corresponding component health status is determined based on the health status characteristic parameters of the at least one component.

[0008] Determine the contribution value of the at least one component to the vehicle's health status;

[0009] Based on the health status of the at least one component and its contribution value, the health status assessment result of the vehicle is obtained.

[0010] Optionally, determining the corresponding component health status based on the health status characteristic parameters of the at least one component includes:

[0011] The lifespan health status of each component is determined based on its remaining lifespan.

[0012] Determine the failure impact rate of each of the aforementioned components;

[0013] The health status of a component is determined by multiplying its lifespan health status and its failure impact rate.

[0014] Optionally, determining the lifespan health status of each component based on its remaining lifespan includes:

[0015] The safe fatigue life of each component is determined based on its structure and material.

[0016] Determine the current usage time of each of the aforementioned components;

[0017] The safe fatigue life is taken as the component life, and the difference between the component life and the corresponding current usage time is calculated to obtain the remaining life of each component.

[0018] The lifespan health status of each component is obtained based on the proportion of its remaining lifespan relative to the lifespan of the corresponding component.

[0019] Optionally, determining the failure impact rate of each of the components includes:

[0020] Determine the target failure type that occurs during the use of each of the aforementioned components;

[0021] The fault impact rate corresponding to the target fault type is determined from the pre-stored correspondence between fault types and fault impact rates.

[0022] Optionally, determining the contribution value of the at least one component to the vehicle's health status includes:

[0023] Determine whether each component meets the preset key component determination conditions;

[0024] The components that meet the preset key component determination conditions are identified as key components of the vehicle, and a corresponding contribution value is assigned to each key component.

[0025] The components that do not meet the preset critical component determination conditions are identified as non-critical components of the vehicle, and a corresponding contribution value is assigned to each non-critical component.

[0026] Among them, the contribution values ​​of different key components are the same or different, the contribution values ​​of different non-key components are the same or different, and the contribution value of each key component is greater than the contribution value of each non-key component.

[0027] Optionally, based on the health status of the at least one component and its contribution value, a health status assessment result of the vehicle is obtained, including:

[0028] When the component is the critical component, the first health status reduction score of the critical component is determined from the first correspondence between the pre-stored component health status and the vehicle score reduction score.

[0029] Based on the first health status reduction score and the contribution value corresponding to each of the key components, the influence score of each of the key components on the first health status of the vehicle is obtained.

[0030] When the component is a non-critical component, the second health status reduction score of the non-critical component is determined from the second correspondence between the pre-stored component health status and the vehicle score reduction score.

[0031] Based on the second health status reduction score and the contribution value corresponding to each of the non-critical components, the influence score of each of the non-critical components on the second health status of the vehicle is obtained.

[0032] The vehicle's health status assessment result is obtained by deducting the first health status impact score corresponding to each of the key components and the second health status impact score corresponding to each of the non-key components from the vehicle's full health status score.

Specifically, other input devices 132 may include, but are not limited to, one or more of the following: physical keyboard, function keys (such as volume control buttons, power buttons, etc.), trackball, mouse, joystick, etc.

[0066] Among them, the input device 132 can receive input data, etc.

[0067] The display unit 140 can be used to display information input by the user or information provided to the user, various menus of the terminal 100, interactive interfaces, file display, and / or playback of any multimedia file.

[0068] The memory 120 can be used to store instructions and data. The memory 120 may primarily include an instruction storage area and a data storage area. The data storage area can store various types of data, such as multimedia files and text. The instruction storage area can store software units such as operating systems, applications, and instructions required for at least one function, or subsets or extended sets thereof. It may also include non-volatile random access memory. It provides the processor 170 with hardware, software, and data resources for managing the computing device, supporting control software and applications. It is also used for storing multimedia files, as well as storing running programs and applications.

[0069] The processor 170 is the control center of the terminal 100. It connects various parts of the terminal 100 via various interfaces and lines. By running or executing instructions stored in the memory 120 and calling data stored in the memory 120, it performs various functions and processes data of the terminal 100, thereby controlling the terminal device as a whole. Optionally, the processor 170 may include one or more processing units; preferably, the processor 170 may integrate an application processor and a modem processor, wherein the application processor mainly handles the operating system, user interface, and applications, and the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into the processor 170. In some embodiments, the processor and memory can be implemented on a single chip; in some embodiments, they can also be implemented separately on independent chips. The processor 170 can also be used to generate corresponding operation control signals, send them to the corresponding components of the computing processing device, read and process data in the software, especially read and process data and programs in the memory 120, so that the various functional modules therein perform corresponding functions, thereby controlling the corresponding components to act according to the instructions.

[0070] The memory 120 can be used to store software code related to the vehicle health status assessment method, and the processor 170 can execute the steps of the vehicle health status assessment method, and can also schedule other units (such as the above-mentioned input unit 130 and display unit 140) to achieve the corresponding functions.

[0071] The radio frequency unit 110 (optional) can be used for receiving and transmitting signals during information transmission or calls. For example, it can receive downlink information from the base station and process it for the processor 170; additionally, it can transmit uplink data to the base station. Typically, the RF circuit includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier (LNA), a duplexer, etc. Furthermore, the radio frequency unit 110 can also communicate wirelessly with network devices and other devices.

[0072] In this embodiment of the application, the radio frequency unit 110 can send data to the server 200 and receive the processing results sent by the server 200.

[0073] It should be understood that the radio frequency unit 110 is optional and can be replaced with other communication interfaces, such as a network port.

[0074] The terminal 100 also includes a power supply 190 (such as a battery) that supplies power to various components. Preferably, the power supply can be logically connected to the processor 170 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system.

[0075] Terminal 100 also includes an external interface 180, which can be a standard Micro USB interface or a multi-pin connector, which can be used to connect terminal 100 to other devices for communication or to connect a charger to charge terminal 100.

[0076] Although not shown, terminal 100 may also include a wireless fidelity (WiFi) module, a Bluetooth module, sensors with different functions, etc., which will not be described in detail here. Some or all of the methods described below can be applied to, for example... Figure 2 In the terminal 100 shown.

[0077] The following description Figure 1 The product form of the mid-range server 200;

[0078] Figure 3 A structural diagram of a server 200 is provided, as follows: Figure 3 As shown, server 200 includes bus 201, processor 202, communication interface 203, and memory 204. Processor 202, memory 204, and communication interface 203 communicate with each other via bus 201.

[0079] Bus 201 can be a Peripheral Component Interconnect (PCI) bus or an Extended Industry Standard Architecture (EISA) bus, etc. Buses can be categorized as address buses, data buses, control buses, etc. For ease of representation, Figure 3 The bus is represented by a single thick line, but this does not mean that there is only one bus or one type of bus.

[0080] The processor 202 can be any one or more of the following processors: central processing unit (CPU), graphics processing unit (GPU), microprocessor (MP), or digital signal processor (DSP).

[0081] Memory 204 may include volatile memory, such as random access memory (RAM). Memory 204 may also include non-volatile memory, such as read-only memory (ROM), flash memory, hard disk drive (HDD), or solid state drive (SSD).

[0082] The memory 204 can be used to store software code related to the vehicle health status assessment method, and the processor 202 can execute the steps of the chip's vehicle health status assessment method, and can also schedule other units to achieve corresponding functions.

[0083] It should be understood that the aforementioned terminal 100 and server 200 can be centralized or distributed devices. The processors (e.g., processor 170 and processor 202) in the aforementioned terminal 100 and server 200 can be hardware circuits (such as application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), general-purpose processors, digital signal processors (DSPs), microprocessors or microcontrollers, etc.) or combinations of these hardware circuits. For example, the processor can be a hardware system with instruction execution capabilities, such as a CPU or DSP, or a hardware system without instruction execution capabilities, such as an ASIC or FPGA, or a combination of the aforementioned hardware systems without instruction execution capabilities and hardware systems with instruction execution capabilities.

[0084] This application provides a method for assessing the health status of a vehicle, which can be applied to... Figure 1 Taking the computer device in the figure as an example, the computer device can specifically be the terminal 100 in the figure above, or a system composed of terminal 100 and server 200. The vehicle health status assessment method of this application embodiment will be described in detail below with reference to the accompanying drawings.

[0085] Reference Figure 4 , Figure 4 This is a flowchart illustrating a vehicle health status assessment method provided in an embodiment of this application. The method includes:

[0086] Step S401: Obtain a request instruction to perform a health status assessment on the vehicle.

[0087] In practical applications, when a driver needs to assess the health status of the vehicle, the driver can send a request command to the vehicle controller to assess the vehicle's health status by entering the vehicle identification number on a mobile app or the vehicle's central control screen.

[0088] The request instruction includes a vehicle identification number (VIN). The VIN is like a vehicle's identification number, determined according to national vehicle management standards, and contains information such as the vehicle's manufacturer, year, model, body style and code, engine code, and assembly location. In practical applications, the VIN can also be other vehicle information, such as license plate number or registration number.

[0089] Step S402: In response to the request instruction, determine at least one component of the vehicle.

[0090] When the vehicle controller receives a request instruction to perform a health status assessment of the vehicle, the vehicle controller responds to the request instruction by identifying at least one component in the vehicle used to assess the vehicle's health status, such as windshield wipers, braking system, steering system, etc.

[0091] Step S403: Determine the corresponding component health status based on the health status characteristic parameters of the at least one component.

[0092] In practical applications, the health status characteristics of each component can be obtained from the vehicle's onboard computer.

[0093] In this embodiment, the health status characteristic parameters of each component include, but are not limited to, component lifespan, current usage time of the component, and faults that occur during the use of the component.

[0094] This involves determining the safe fatigue life of each component based on its structure and materials, and defining this safe fatigue life as the component's lifespan. The current usage time of each component is determined by querying the vehicle's backend records regarding the number of times each component has been used.

[0095] Faults that occur in parts during use can be directly checked in the vehicle's onboard computer.

[0096] Step S404: Determine the contribution value of the at least one component to the vehicle's health status.

[0097] In this embodiment, the contribution value of a component to the vehicle's health status refers to the weight value of the component's influence on the vehicle's health status, that is, the importance of the component's influence on the vehicle's health status. Different components may have the same or different contribution values ​​to the vehicle's health status.

[0098] In this embodiment, the principle for dividing the contribution values ​​of each component is as follows: with a total of 1, the higher the importance of the component, the greater its corresponding contribution value; conversely, the lower the importance of the component, the smaller its corresponding contribution value. The specific contribution value of each component can be determined by the relevant professional department based on the actual situation, and this invention does not impose any limitations on this.

[0099] Step S405: Based on the health status of the at least one component and the contribution value, obtain the health status assessment result of the vehicle.

[0100] In practical applications, based on the health status and contribution value of each component, the impact score of that component on the overall vehicle health status can be determined. Therefore, based on the impact scores of each component on the overall vehicle health status, a vehicle health status assessment result can be obtained. This assessment result can then determine whether the vehicle requires maintenance or repair, thus avoiding impacts on user driving safety and driving experience.

[0101] In summary, this invention discloses a vehicle health status assessment method. The method involves obtaining a request instruction to assess the vehicle's health status, responding to the request instruction to identify at least one component of the vehicle, determining the corresponding component's health status based on its health status characteristic parameters, determining the contribution value of the at least one component to the vehicle's health status, and obtaining the vehicle's health status assessment result based on the component's corresponding health status and contribution value. This invention achieves automatic vehicle health status assessment by determining the component's health status and contribution value for at least one component. The entire process requires no manual intervention, significantly saving manpower and time, and ensuring the accuracy of the vehicle health status assessment results, thereby effectively avoiding over-maintenance. Furthermore, this invention can promptly detect vehicle malfunctions, allowing for timely and effective measures to avoid impacting user driving safety and driving experience.

[0102] To further optimize the above embodiments, see [link to relevant documentation]. Figure 5 The flowchart of a method for determining the health status of a component disclosed in this embodiment of the invention, specifically step S403, may include:

[0103] Step S501: Determine the life health status of each component based on its remaining lifespan.

[0104] It is understandable that each component of a vehicle has its own lifespan. In practical applications, the lifespan and health status of a component can be assessed based on the time elapsed between its testing date and its manufacturing date.

[0105] Step S502: Determine the failure impact rate of each component.

[0106] Specifically, the target fault types that occur during the use of each component are determined, and the fault impact rate corresponding to the target fault type is determined from the pre-stored correspondence between fault types and fault impact rates.

[0107] The following is an example of the correspondence between fault type and fault impact rate:

[0108] The fault type is: severe deformation or damage of components. The corresponding fault impact rate is 0.

[0109] The fault type is: the component shows visible damage, but can still be used. The corresponding fault impact rate is 80%.

[0110] The fault type is characterized by no visible damage to the components. The corresponding fault impact rate is 1.

[0111] Step S503: Determine the component health status by multiplying the life health status and failure impact rate of each component.

[0112] The expression for the health status of components is as follows:

[0113] C = A × B;

[0114] In the formula, C represents the health status of the component, A represents the life health status of the component, and B represents the failure impact rate.

[0115] In practical applications, when the health status of a component is lower than the first preset value (e.g., 80%), the component is considered to be warranted for repair; when the health status of a component is lower than the second preset value (e.g., 40%), the component is considered to be replaced.

[0116] To further optimize the above embodiments, see [link to relevant documentation]. Figure 6 The present invention discloses a method for determining the lifespan health status of each component based on its remaining lifespan. The method includes:

[0117] Step S601: Determine the safe fatigue life of each component based on its structure and material.

[0118] In practical applications, the safe fatigue life of each component can be calculated based on its structure and material. For the specific calculation process, please refer to the existing solutions, which will not be elaborated here.

[0119] Step S602: Determine the current usage time of each component.

[0120] The number of times each component has been used can be queried based on the vehicle's backend records to determine the current usage time of each component.

[0121] Step S603: Using the safe fatigue life as the component life, calculate the difference between the component life and the corresponding current usage time to obtain the remaining life of each component.

[0122] Step S604: Based on the ratio of the remaining lifespan to the lifespan of the corresponding component, obtain the lifespan health status of each component.

[0123] The formula for calculating the lifespan and health status of each component is as follows:

[0124]

[0125] In the formula, A represents the life health status of the component, X represents the life of the component, and x represents the current usage time of the component.

[0126] In summary, this invention obtains the remaining lifespan of each component based on its current usage time and lifespan. By determining the proportion of the remaining lifespan of a component to its total lifespan, the health status of each component is obtained, enabling subsequent evaluation of the component's health status and providing a reference for the subsequent evaluation of the vehicle's health status, thus achieving automatic evaluation of the vehicle's health status.

[0127] To further optimize the above embodiments, see [link to relevant documentation]. Figure 7 The present invention discloses a flowchart of a method for determining the contribution value of at least one component to the health status of a vehicle. The method includes:

[0128] Step S701: Determine whether each component meets the preset key component judgment conditions.

[0129] Among them, the preset criteria for determining key components can be: the component is of high importance to the whole vehicle, has an impact on driver safety (or affects driving safety), or belongs to any one or more of the automotive regulatory components.

[0130] Automotive regulatory parts refer to components that are subject to national mandatory automotive standards and domestic certification, and that require filing relevant information with the national competent authority and ensuring consistency in subsequent production and sales.

[0131] Automotive regulatory components include body control assemblies, air conditioning assemblies, key wiring harnesses, etc., mainly components related to the safety of the entire vehicle.

[0132] For example, windshield wipers affect driving safety in rainy weather; therefore, windshield wipers can be considered a critical component of a vehicle.

[0133] Braking and steering systems also affect driving safety; therefore, they can also be considered key components of a vehicle.

[0134] Step S702: Determine the components that meet the preset key component determination conditions as key components of the vehicle, and assign corresponding contribution values ​​to each key component.

[0135] Step S703: Determine the components that do not meet the preset critical component determination conditions as non-critical components of the vehicle, and assign corresponding contribution values ​​to each non-critical component.

[0136] In this embodiment, the principle for dividing the contribution value of each component is as follows: with 1 as the sum, the higher the importance of the component, the greater the corresponding contribution value; conversely, the lower the importance of the component, the smaller the corresponding contribution value.

[0137] The contribution values ​​of different key components may be the same or different, the contribution values ​​of different non-key components may be the same or different, and the contribution value of each key component is greater than the contribution value of each non-key component.

[0138] For example, the key component is the braking system, which affects driving safety and is of high importance in the vehicle. Therefore, the contribution value allocated to the braking system is relatively high, such as 0.3.

[0139] The non-critical component is the seat heating system. The seat heating system has a relatively low importance in the vehicle, so the contribution value allocated to the seat heating system is relatively low, such as 0.02.

[0140] It should be noted that the contribution values ​​of each component can be determined by the respective professional departments based on the actual situation, and this invention does not impose any restrictions on them.

[0141] To further optimize the above embodiments, step S405 may specifically include:

[0142] (1) When the component is a critical component, the first health status reduction score of the critical component is determined from the first correspondence between the pre-stored component health status and the vehicle score reduction score.

[0143] (2) Based on the first health status reduction score and contribution value of each key component, the influence score of each key component on the first health status of the vehicle is obtained.

[0144] (3) When the component is a non-critical component, the second health status reduction score of the non-critical component is determined from the second correspondence between the pre-stored component health status and the vehicle score reduction score.

[0145] (4) Based on the reduction score and contribution value of the second health status corresponding to each non-critical component, the influence score of each non-critical component on the second health status of the vehicle is obtained.

[0146] (5) From the full score of vehicle health status, deduct the first health status impact score corresponding to each key component and the second health status impact score corresponding to each non-key component to obtain the vehicle health status assessment result.

[0147] It should be noted that, since critical components and non-critical components have different impacts on the overall vehicle health status, this embodiment sets different health status reduction scores for critical components and non-critical components.

[0148] For critical components, the corresponding reduction score for the first health status can be the same or different for different critical components. For example, when the component's health status is below 80%, the corresponding reduction score for the first health status is 10 points. When the component's health status is below 90%, the corresponding reduction score for the first health status is 5 points. When the component's health status is below 40%, the corresponding reduction score for the first health status is 20 points. In this case, the overall vehicle score can also be set to 60 points.

[0149] For non-critical components, the reduction score for the second health status can be the same or different for different critical components. For example, when the component's health status is below 90%, the corresponding reduction score for the second health status is 1 point. When the component's health status is below 40%, the corresponding reduction score for the second health status is 5 points.

[0150] The above describes a vehicle health status assessment method provided by the embodiments of this application. The following describes the apparatus for performing the above-described vehicle health status assessment method.

[0151] Please see Figure 8 , Figure 8 This is a schematic diagram of a vehicle health status assessment device provided in an embodiment of this application.

[0152] like Figure 8 As shown, the device includes:

[0153] The request instruction acquisition unit 801 is used to acquire a request instruction for a health status assessment of the vehicle, wherein the request instruction carries a vehicle identification identifier.

[0154] In practical applications, when a driver needs to assess the health status of the vehicle, the driver can send a request command to the vehicle controller to assess the vehicle's health status by entering the vehicle identification number on a mobile app or the vehicle's central control screen.

[0155] The request instruction includes a vehicle identification number (VIN). The VIN is like a vehicle's identification number, determined according to national vehicle management standards, and contains information such as the vehicle's manufacturer, year, model, body style and code, engine code, and assembly location. In practical applications, the VIN can also be other vehicle information, such as license plate number or registration number.

[0156] The component determination unit 802 is used to determine at least one component of the vehicle in response to the request instruction.

[0157] When the vehicle controller receives a request instruction to perform a health status assessment of the vehicle, the vehicle controller responds to the request instruction by identifying at least one component in the vehicle used to assess the vehicle's health status, such as windshield wipers, braking system, steering system, etc.

[0158] The component health status determination unit 803 is used to determine the corresponding component health status based on the health status characteristic parameters of the at least one component.

[0159] In this embodiment, the health status characteristic parameters of each component include, but are not limited to, component lifespan, current usage time of the component, and faults that occur during the use of the component.

[0160] The contribution value determination unit 804 is used to determine the contribution value of the at least one component to the vehicle's health status.

[0161] In this embodiment, the contribution value of a component to the vehicle's health status refers to the weight value of the component's influence on the vehicle's health status, that is, the importance of the component's influence on the vehicle's health status. Different components may have the same or different contribution values ​​to the vehicle's health status.

[0162] In this embodiment, the principle for dividing the contribution values ​​of each component is as follows: with a total of 1, the higher the importance of the component, the greater its corresponding contribution value; conversely, the lower the importance of the component, the smaller its corresponding contribution value. The specific contribution value of each component can be determined by the relevant professional department based on the actual situation, and this invention does not impose any limitations on this.

[0163] The health status assessment unit 805 is used to obtain the health status assessment result of the vehicle based on the health status of the at least one component and the contribution value of the component.

[0164] In practical applications, based on the health status and contribution value of each component, the impact score of that component on the overall vehicle health status can be determined. Therefore, based on the impact scores of each component on the overall vehicle health status, a vehicle health status assessment result can be obtained. This assessment result can then determine whether the vehicle requires maintenance or repair, thus avoiding impacts on user driving safety and driving experience.

[0165] In summary, this invention discloses a vehicle health status assessment device. It acquires a request command to assess the health status of a vehicle, determines at least one component of the vehicle in response to the request command, determines the corresponding component's health status based on the health status characteristic parameters of the at least one component, determines the contribution value of the at least one component to the vehicle's health status, and obtains the vehicle's health status assessment result based on the component's corresponding health status and contribution value. This invention achieves automatic assessment of the vehicle's health status by determining the component's health status and contribution value corresponding to at least one component. The entire process requires no manual intervention, significantly saving manpower and time, and ensuring the accuracy of the vehicle health status assessment results, thereby effectively avoiding over-maintenance. Furthermore, this invention can also promptly detect vehicle malfunctions, allowing for timely and effective measures to avoid impacting user driving safety and driving experience.

[0166] To further optimize the above embodiments, the component health status determination unit 803 specifically includes:

[0167] The lifespan health status determination subunit is used to determine the lifespan health status of each component based on the remaining lifespan of each component.

[0168] The failure impact rate determination subunit is used to determine the failure impact rate of each of the aforementioned components;

[0169] The component health status determination subunit is used to determine the component health status by multiplying the life health status corresponding to each component and the failure impact rate.

[0170] The following is an example of the correspondence between fault type and fault impact rate:

[0171] The fault type is: severe deformation or damage of components. The corresponding fault impact rate is 0.

[0172] The fault type is: the component shows visible damage, but can still be used. The corresponding fault impact rate is 80%.

[0173] The fault type is characterized by no visible damage to the components. The corresponding fault impact rate is 1.

[0174] To further optimize the above embodiments, the lifespan health status determination subunit can specifically be used for:

[0175] The safe fatigue life of each component is determined based on its structure and material.

[0176] Determine the current usage time of each of the aforementioned components;

[0177] The safe fatigue life is taken as the component life, and the difference between the component life and the corresponding current usage time is calculated to obtain the remaining life of each component.

[0178] The lifespan health status of each component is obtained based on the proportion of its remaining lifespan relative to the lifespan of the corresponding component.

[0179] To further optimize the above embodiments, the fault impact rate determination subunit can specifically be used for:

[0180] Determine the target failure type that occurs during the use of each of the aforementioned components;

[0181] The fault impact rate corresponding to the target fault type is determined from the pre-stored correspondence between fault types and fault impact rates.

[0182] To further optimize the above embodiments, the contribution value determination unit 804 may specifically include:

[0183] The judgment subunit is used to determine whether each component meets the preset key component judgment conditions;

[0184] The key component determination subunit is used to determine the component that meets the preset key component determination conditions as the key component of the vehicle when the determination subunit determines it as yes, and to assign a corresponding contribution value to each key component.

[0185] The non-critical component determination subunit is used to determine the component that does not meet the preset critical component determination condition as a non-critical component of the vehicle when the determination subunit determines it as no, and to assign a corresponding contribution value to each non-critical component.

[0186] Among them, the contribution values ​​of different key components are the same or different, the contribution values ​​of different non-key components are the same or different, and the contribution value of each key component is greater than the contribution value of each non-key component.

[0187] To further optimize the above embodiments, the health status assessment unit 805 can specifically be used for:

[0188] When the component is the critical component, the first health status reduction score of the critical component is determined from the first correspondence between the pre-stored component health status and the vehicle score reduction score.

[0189] Based on the first health status reduction score and the contribution value corresponding to each of the key components, the influence score of each of the key components on the first health status of the vehicle is obtained.

[0190] When the component is a non-critical component, the second health status reduction score of the non-critical component is determined from the second correspondence between the pre-stored component health status and the vehicle score reduction score.

[0191] Based on the second health status reduction score and the contribution value corresponding to each of the non-critical components, the influence score of each of the non-critical components on the second health status of the vehicle is obtained.

[0192] The vehicle's health status assessment result is obtained by deducting the first health status impact score corresponding to each of the key components and the second health status impact score corresponding to each of the non-key components from the vehicle's full health status score.
