[0045] The user device 10 can include a processor, a memory, and a communication interface, and can refer to the description of the vehicle-mounted device, which will not be described here.

[0046] In view of the problem in the prior art that the components of the vehicle can be illegally disassembled, the present application provides a method for prompting the absence of a vehicle component. The method can be executed by a device for prompting the absence of a vehicle component. The device can be implemented by software and / or hardware, and can be integrated in an emergency power supply or a vehicle (or a vehicle-mounted device). By implementing the present application, in the case where the original power supply of the vehicle is missing, the absence of other components in the vehicle can be detected, and the anti-theft monitoring of the vehicle components can be realized. The absence of the missing components is prompted, which is beneficial to improving the efficiency of handling the component absence event.

[0047] Specifically, please refer to Figure 3 , Figure 3is a flowchart of a method for prompting a missing part of a vehicle part provided by the present application. The method is exemplified by taking an emergency power supply as an example, the emergency power supply is deployed in a vehicle, the vehicle includes an original power supply and at least two parts. The method includes the following steps S301-S304, wherein:

[0048] S301, the emergency power supply receives the missing indication of the original power supply of the vehicle, and the original power supply is taken as the missing first part to supply power to the vehicle.

[0049] The missing indication is used to indicate that the original power supply of the vehicle is missing. The missing indication can be a command sent by the user after detecting that the original power supply is missing, or a self-detection of the vehicle. The method for the vehicle to self-detect whether the original power supply is missing is not limited in the present application, an instrument can be arranged below the original power supply to obtain the weight of the original power supply. When the weight of the original power supply is 0 or less than a threshold, it is determined that the original power supply is missing. Or it can be determined whether the part powered by the power supply can work to determine whether the original power supply is missing. For example, in the case that there is a part that can work, it is determined that the part is powered and the original power supply is not missing. In the case that there is no part that can work, it is determined that the part is not powered and the original power supply is the missing part.

[0050] In the embodiment of the present application, the missing part in the vehicle is taken as the first part. If the missing indication of the original power supply is received, it means that the original power supply is missing, and the original power supply can be taken as the first part. It can be understood that after the original power supply is missing, the parts in the vehicle are in a power-off state and cannot work. The emergency power supply in the vehicle can be used to power the vehicle, specifically to power the parts in the vehicle that are not missing.

[0051] S302, the emergency power supply detects the communication signals of each part in the vehicle.

[0052] S303, the emergency power supply takes the part for which no communication signal is detected as the first part.

[0053] In the embodiment of the present application, a communication module can be arranged in the interior of the emergency power supply and the interior of the part for data communication. The communication module can include a UWB module, a Bluetooth module, an infrared module, an NFC module, etc. as described above, which is not limited herein. Based on this, the communication signal of the part detected by the emergency power supply can be a UWB signal, a Bluetooth signal, an infrared signal, an NFC signal, etc.

[0054] It can be understood that, after the emergency power supply supplies power to the vehicle, the components in the vehicle that are not missing can work and emit communication signals. If the communication signals of the components are detected, it indicates that the components have been successfully powered by the emergency power supply and can work normally and communicate data with the emergency power supply. If the communication signals of the components are not detected, it indicates that the electrical connection between the components and the emergency power supply is disconnected, and the components can be the components that are missing in the vehicle. Therefore, the components can be taken as the first components.

[0055] In a possible example, step S302 can be performed within a preset time period after step S301, and the components that do not receive the communication signals are taken as the first components. In this way, the (first) components that are missing in the vehicle in addition to the original power supply can be detected.

[0056] The preset time period can be one time period, for example, 1 minute after step S301, or 5 seconds after the communication signals of the components are detected. For example, the communication signals of component B are detected within 5 seconds after the communication signals of component A are detected. The communication signals of component C are detected within 5 seconds after the communication signals of component B are detected. If the communication signals of components D and E are not detected within 5 seconds after the communication signals of component C are detected, components D and E are taken as the first components. The preset time period can also be multiple time periods, for example, the preset time period of component A is 5 seconds, and the preset time period of component B is 10 seconds.

[0057] The preset time period can be obtained by presetting, or can be determined based on the time period in which the communication signals of the components are detected from historical communication records, or based on the power and signal strength of the components, etc. The size and determination method of the preset time period are not limited in the present application.

[0058] S304, the emergency power supply outputs a missing prompt of the first components.

[0059] In the embodiments of the present application, the missing prompt is used to prompt the missing of the first components. The missing prompt can include the name of the first components, the time when the missing of the first components is determined, the location of the vehicle, etc. The missing prompt can also include the components that can be missing, the missing reason of the first components, etc., which are not limited herein. The object to which the missing prompt is output is also not limited, which can be the owner of the vehicle or the family, friends, colleagues, etc. of the owner of the vehicle, or can be the developers, testers or customer service personnel, etc. of the server corresponding to the vehicle, or can be the relevant staff of the vehicle repair point, the vehicle management office, the police station or the insurance company, etc.

[0060] It should be noted that the missing prompt of the first components can be output respectively or by using the same information, which is not limited herein.

[0061] In Figure 3 the method shown, after the emergency power supply receives the indication of the absence of the original power supply of the vehicle, the original power supply is regarded as the missing part, and the vehicle is powered to enable the parts in the vehicle to work and emit communication signals. Then the emergency power supply detects the communication signals of the parts of the vehicle. If the communication signals of the parts are not detected, it is determined that the parts are also missing parts. Then the absence prompt of the missing parts is output. In this way, in the case of the absence of the original power supply of the vehicle, the absence detection is performed on other parts in the vehicle, and the anti-theft monitoring of the parts of the vehicle can be realized. And the absence prompt of the missing parts is beneficial to improve the efficiency of handling the part absence event.

[0062] Consistent with Figure 3 embodiments, refer to Figure 4 , Figure 4 is a flowchart of another method for prompting the absence of vehicle parts provided by the present application. Taking the application of the emergency power supply as an example, the emergency power supply is deployed in the vehicle, and the vehicle includes an original power supply and at least two parts. The method includes the following steps S401-S408, wherein:

[0063] S401, the emergency power supply receives the indication of the absence of the original power supply of the vehicle, and regards the original power supply as the first missing part to power the vehicle.

[0064] S402, the emergency power supply detects the communication signals of each part in the vehicle.

[0065] S403, the emergency power supply regards the part that detects the communication signal as the second non-missing part.

[0066] S404, the emergency power supply regards the part that does not detect the communication signal as the first part.

[0067] It can be understood that after the emergency power supply powers the vehicle, the parts in the vehicle can emit communication signals. After the emergency power supply detects the communication signals of the parts of the vehicle, it can be determined that the parts can work normally and are not missing parts in the vehicle. Therefore, the detection of the communication signals of the parts of the vehicle can be regarded as the second non-missing part in the vehicle.

[0068] It should be noted that step S403 can be executed before step S404. That is, after determining the second non-missing part, the second non-missing part is excluded from the parts in the vehicle to obtain the parts that do not detect the communication signals. However, step S403 can be executed simultaneously with step S404, or step S403 can be executed after step S404.

[0069] For example, the preset time length for detecting the communication signal of the part A and the part B is 5 seconds after the step S401. Assuming that the communication signal of the part A is detected 3 seconds after the step S401, and the communication signal of the part B is not detected within 5 seconds after the step S401, the step S403 and the step S404 can be executed when 5 seconds after the step S401 arrives. Or the step S403 is executed when 3 seconds after the step S401 arrives, and the step S404 is executed when 5 seconds after the step S401 arrives.

[0070] For another example, the preset time length for detecting the communication signal of the part A is 5 seconds after the step S401, and the preset time length for detecting the communication signal of the part B is 2 seconds after the step S401. Assuming that the communication signal of the part A is detected 3 seconds after the step S401, and the communication signal of the part B is not detected within 2 seconds after the step S401, the step S403 and the step S404 can be executed when 5 seconds after the step S401 arrives. Or the step S404 is executed when 2 seconds after the step S401 arrives, and the step S403 is executed when 3 seconds after the step S401 arrives.

[0071] S405, the emergency power supply obtains the first device information of the first part and the second device information of the second part.

[0072] In the embodiment of the present application, the device information of the part can include the name, number, model and the like of the part. The device information of the part can also include the use information of the part, such as the use time length, use frequency, use life, maintenance frequency, historical maintenance record, and the like, which are not limited herein. The device information of the first part can be referred to as the first device information, and the device information of the second part can be referred to as the second device information. The first device information and the second device information can be obtained from the data stored in the server by the vehicle, and can also be obtained based on the use record of the part. Or a device information obtaining instruction is sent to the user to receive the device information sent by the user, and the like, which are not limited herein.

[0073] S406, the emergency power supply obtains the stolen probability of the first part based on the first device information and the second device information.

[0074] The stolen probability is used to describe the possibility of the first part being illegally disassembled for resale. It can be understood that the reason for the absence of the first part can be not only illegal disassembly, but also device damage, repair or replacement. Based on this, the stolen probability or the absence reason determined based on the stolen probability can be prompted in the absence prompt of the first part, which can improve the comprehensiveness of the prompt.

[0075] The method for obtaining the stolen probability is not limited in the present application. It can be understood that the probability of damage of a component with a higher frequency of use and a longer duration of use is higher, and the probability of theft is lower. The probability of damage of a component with a lower frequency of use and a shorter duration of use is lower, and the probability of theft is higher. In this way, the damage probability can be obtained based on the use of the component, and the stolen probability can be obtained by subtracting the damage probability from 1. Alternatively, the stolen probability can be obtained based on the use of the component.

[0076] The component itself has a certain value, therefore, the component that is not usually traded is usually not the component that needs to be repaired or replaced, and the stolen probability can be determined based on the size of the income obtained by reselling the component. For example, a component such as a power supply that has a value itself, or a general component, has a high income obtained by illegal disassembly for trading, and the stolen probability is high.

[0077] Since there can be an electrical connection between components, in the case of damage to one component, another component can also be damaged. Or the duration of damage of one component can be shorter than that of another component. Therefore, the damage relationship between components can be pre-stored. In the case of assuming that the first component is damaged and needs to be repaired or replaced, the abnormal value or normal value of the second component not being damaged can be obtained based on the damage relationship between the first component and the second component. Alternatively, in the case of assuming that the second component is not damaged, the abnormal value or normal value of the first component being damaged can be obtained based on the damage relationship between the first component and the second component. Then the stolen probability of the first component can be calculated based on the abnormal value or normal value. For example, the abnormal value is taken as the stolen probability, or the difference between 1 and the normal value is taken as the stolen probability, etc.

[0078] Since components can be sold in combination, the combination relationship between components can be pre-stored. In the case of assuming that the first component is illegally disassembled, the abnormal value or normal value of the second component not being illegally disassembled can be obtained based on the combination relationship between the first component and the second component. Alternatively, in the case of the second component not being illegally disassembled, the abnormal value or normal value of the first component being illegally disassembled can be obtained based on the combination relationship between the first component and the second component. Then the stolen probability of the first component can be calculated based on the abnormal value or normal value. For example, the abnormal value is taken as the stolen probability, or the difference between 1 and the normal value is taken as the stolen probability, etc.

[0079] In one possible example, step S406 can include the following steps A1 and A2, wherein:

[0080] A1, the emergency power supply obtains the association relationship between the first component and the second component based on the first device information and the second device information.

[0081] The association relationship can be an electrical connection relationship, a damage relationship, a matching relationship, or the like between the first component and the second component. The application does not limit the association relationship, and the method of obtaining the association relationship is not limited. The same type of information in each device information can be analyzed, or the association relationship can be obtained based on a pre-constructed knowledge graph of components and components.

[0082] A2, the emergency power supply obtains the stolen probability of the first component based on the first device information and the association relationship.

[0083] As described above, based on the association relationship between the first component and the second component and the first device information, the probability of the first component being repaired or replaced due to device damage or the probability of being stolen due to illegal disassembly can be obtained. Therefore, in steps A1 and A2, the stolen probability of the first component is obtained based on the first device information and the association relationship, which can improve the accuracy of obtaining the stolen probability.

[0084] The application does not limit the method of obtaining the stolen probability based on the first device information and the association relationship, and the stolen sub-probability of the first component being stolen due to illegal disassembly can be obtained based on the first device information and the association relationship between the first component and the second component, respectively. Then, the stolen sub-probability is weighted with the preset weight of the first device information and the association relationship, respectively, to obtain the stolen probability of the first component.

[0085] For example, assuming that the stolen sub-probability obtained based on the first device information, the association relationship between the first component and the second component is 0.6, 0.4, respectively. If the preset weight of the first device information and the association relationship is 0.6, 0.4, respectively, the stolen probability of the first component can be equal to 0.6*0.6+0.4*0.4, i.e. 0.52.

[0086] In one possible example, step A2 can include the following steps A21-A23, wherein:

[0087] A21, the emergency power supply obtains a first probability of damage and loss of the first component based on the first device information.

[0088] The first probability is used to describe the possibility that the first component is missing due to device damage. Specifically, the first probability can be determined based on the use information of the first component obtained from the first device information. For example, the greater the use frequency and the longer the use time, the greater the first probability. The first probability can also be determined based on the historical repair record of the first component obtained from the first device information. For example, the longer the repair time interval, the greater the repair frequency, and the more the repair times, the greater the first probability.

[0089] Or the difference between 1 and the reselling probability of the first spare part obtained based on the first device information can be taken as the first probability. It can be understood that the greater the reselling probability, the smaller the first probability. The application does not limit the method for obtaining the reselling probability, which can be obtained based on the usage information of the first spare part. For example, the greater the usage frequency and the longer the usage time, the smaller the value obtained by reselling compared to the value of selling new spare parts, that is, the smaller the reselling probability. The reselling probability can also be obtained based on the demand information of the first spare part. For example, the greater the demand for the spare part, the greater the reselling probability.

[0090] A22, the emergency power supply obtains a second probability of the second spare part not being damaged and missing based on the association relationship.

[0091] The second probability is used to describe the possibility that the second spare part is not damaged and missing in the case that the first spare part is missing due to device damage. As described above, there can be a damage relationship between the spare parts and the spare parts. Therefore, the second probability that the second spare part is not damaged and missing in the case that the first spare part is damaged and missing can be determined based on the association relationship between the first spare part and the second spare part. Or since the sum of the probability that the second spare part is damaged and missing and the second probability that the second spare part is not damaged and missing is 1 in the case that the first spare part is missing due to device damage, the probability that the second spare part is damaged and missing in the case that the first spare part is damaged and missing can be determined based on the association relationship between the first spare part and the second spare part. The difference between 1 and the probability is obtained to obtain the second probability that the second spare part is not damaged and missing.

[0092] Exemplarily, it is assumed that there is a damage relationship between the first spare part and the second spare part, and based on the damage relationship, the probability that the second spare part is damaged and missing in the case that the first spare part is missing due to damage is 0.4, then the second probability that the second spare part is not damaged is 1-0.4, that is, 0.6.

[0093] A23, the emergency power supply calculates the stolen probability of the first spare part based on the first probability and the second probability.

[0094] The application does not limit the method for calculating the stolen probability, since the cause of the spare part missing is illegal disassembly in addition to damage, the sum of the target probability of missing due to damage and the stolen probability of missing due to illegal disassembly is 1. Therefore, the stolen probability can be obtained by the difference between 1 and the target probability. The target probability is used to describe the possibility that the missing cause of the event that the first spare part is missing and the second spare part is not missing is that the first spare part device is damaged. The target probability can be equal to the weighted value between the first probability and the second probability. The application does not limit the preset weight value corresponding to the first probability and the second probability.

[0095] Exemplarily, the first probability is 0.4, and the second probability is 0.6. If preset weights corresponding to the first probability and the second probability are 0.6 and 0.4 respectively, the target probability can be equal to 0.4*0.6+0.6*0.4, that is, 0.48. The stolen probability can be equal to 1-0.48, that is, 0.52.

[0096] It should be noted that the present application does not limit the execution order of steps A21 and A22. They can be executed simultaneously, or step A21 can be executed first and then step A22, or step A22 can be executed first and then step A21.

[0097] It can be understood that in steps A21-A23, the damage probability of the first spare part being repaired or replaced due to equipment damage obtained based on the first equipment information, and the damage coefficient of the second spare part not being missing for the first spare part being damaged obtained based on the association relationship between the first spare part and the second spare part, can obtain the probability of whether the missing reason of the first spare part is equipment damage. Since the missing reason of the spare part is illegal disassembly in addition to equipment damage, the stolen probability of the first spare part can be calculated from the perspective of whether the missing reason of the first spare part is equipment damage, which can improve the accuracy of obtaining the stolen probability and is beneficial to analyzing the missing reason of the first spare part.

[0098] S407, the emergency power supply generates a missing prompt of the first spare part based on the stolen probability of the first spare part.

[0099] It can be understood that the smaller the stolen probability is, the smaller the possibility of illegal disassembly is, and the larger the possibility of repair or replacement is. The missing prompt of the first spare part can prompt that the first spare part is missing and ask the user to confirm whether it is a repair or replacement event. The larger the stolen probability is, the larger the possibility of illegal disassembly is, and the smaller the possibility of repair or replacement is. The missing prompt of the first spare part can prompt that the first spare part is missing and ask the user to confirm whether it is a stolen event. The missing prompt can also be output to the traffic management department, the insurance department, etc.

[0100] In one possible example, the missing prompt includes a missing reason. The emergency power supply can be configured to execute the following steps: regarding the missing reason of the first spare part with a stolen probability less than a first threshold value as equipment damage; or regarding the missing reason of the first spare part with a stolen probability greater than or equal to the first threshold value as illegal disassembly.

[0101] The first threshold value is not limited, for example, 0.6, etc. The method for determining the first threshold value is not limited. The accuracy of the missing reason fed back by the user after receiving the missing reason prompt can be used to set the first threshold value. For example, when the accuracy is low, the first threshold value can be increased. Or it can be set based on the frequency of damage or the frequency of theft of the first component. For example, the first threshold value of the first component with low damage frequency can be 0.4, the first threshold value of the first component with high damage probability can be 0.6, etc. For example, the first threshold value of the first component with high theft frequency can be 0.5, and the first threshold value of the first component with low theft frequency can be 0.7.

[0102] It can be understood that in this example, based on the size relationship between the theft probability and the first threshold value, it is determined whether the missing reason is device damage or illegal disassembly. Including the missing reason in the missing prompt can assist in determining the security of the missing event, and is beneficial to improve the efficiency and accuracy of processing component missing events.

[0103] In a possible example, the missing prompt includes location information of the vehicle. The location information is used to describe the current location of the vehicle. It can be described by latitude and longitude, or route or nearby location, which is not limited here. It can be understood that when the positioning module of the vehicle is not missing, the location information of the vehicle can be obtained through the positioning module. The location information of the vehicle can also be obtained based on the communication signal of the second component. For example, a communication module is set in advance at an intersection. If the communication module also detects the communication signal of the second component, the position of the second component is obtained based on the strength of the communication signal and the position of the communication module at the intersection, so as to obtain the location information of the vehicle.

[0104] The following takes the communication signal as an example of UWB signal. In a possible example, the communication signal of the second component is a first UWB signal, and the emergency power supply is further used to execute the steps comprising: detecting a second UWB signal of a reference device other than the first UWB signal; obtaining location information of the reference device; and obtaining the location information of the vehicle based on the location information of the reference device and the orientation parameter.

[0105] The second UWB signal carries the orientation parameter of the reference device transmitting the second UWB signal, which can include the distance between the reference device and the emergency power supply, whether there is an obstruction between the reference device and the emergency power supply, the signal strength of the second UWB signal, etc., which is not limited here.

[0106] The reference device can be any device with a UWB module other than the vehicle, such as a road side unit (RSU), and the like, which is not limited herein. The position information of the reference device can be information carried in the UWB signal fed back by the reference device after receiving the UWB signal sent by the emergency device. The position information of the reference device can be obtained by the identification information of the reference device carried in the second UWB signal, which is not limited herein.

[0107] It can be understood that in this example, the emergency power supply detects the second UWB signal of the reference device other than the first UWB signal of the second component. The position information of the emergency power supply is obtained based on the position information of the reference device and the orientation parameter, thereby obtaining the position information of the vehicle. In this way, the position information of the vehicle is obtained by means of the position information of the reference device capable of transmitting communication signals and the orientation parameter between the reference device and the emergency power supply, which can improve the accuracy of positioning.

[0108] In a possible example, the missing prompt includes a third component that can be missing. The emergency power supply can further be configured to perform the following steps: obtaining a stolen probability of the second component based on the association relationship between the first component and the second component and the second device information; and taking the second component with the stolen probability greater than a second threshold as the third component.

[0109] The second threshold can be equal to or different from the first threshold, which is not limited herein. The method for obtaining the stolen probability of the second component can refer to the description of the stolen probability of the first component, which is not repeated herein. It can be understood that the third component that can be missing is prompted in the missing prompt, which can improve the anti-theft monitoring of the component that is temporarily not missing, and is beneficial to improve the efficiency of handling the component missing event.

[0110] In a possible example, step S407 can include the following steps: obtaining the position information of the vehicle; taking the missing reason of the first component with the stolen probability less than the first threshold as device damage; and generating a missing prompt of the first component based on the missing reason and the position information.

[0111] Alternatively, in a possible example, step S407 can include the following steps: obtaining the position information of the vehicle; taking the missing reason of the first component with the stolen probability greater than or equal to the first threshold as device damage; and generating a missing prompt of the first component based on the missing reason and the position information.

[0112] In the above two examples, the missing reason is obtained based on the size of the stolen probability. The missing prompt is generated based on the missing reason and the position information of the vehicle, which can prompt the current position of the vehicle and is beneficial to improve the efficiency of tracking the missing component. The missing reason of the component can also be prompted, which can improve the accuracy of handling the component missing event.

[0113] S408, Warning of missing first component of emergency power output.

[0114] In one possible example, step S408 may include the following steps: the emergency power supply determines the notification object corresponding to the probability of the first component being stolen; the emergency power supply sends a notification of the missing first component to the notification object.

[0115] The recipients of the notification can be the vehicle owner or their family, friends, or colleagues; or the developers, testers, or customer service personnel of the server corresponding to the vehicle; or relevant staff at vehicle repair shops, vehicle management offices, police stations, or insurance companies that handle illegal dismantling incidents. There are no restrictions on who can receive the notification.

[0116] Since the first component includes both the original power supply and the component that did not detect a communication signal, the number of the first components is greater than or equal to 2. The target of the notification can be determined based on the maximum or minimum probability of the first component being stolen, or it can be determined based on the average or weighted probability of the first component being stolen, etc., without limitation here.

[0117] It should be noted that the number of notification objects can be one or more. When there are multiple notification objects, the same or different missing notifications can be sent to them.

[0118] In this example, the corresponding notification object is determined based on the probability of the first component being stolen. Then, a missing component notification corresponding to the probability of theft is output to the notification object. This allows for sending missing component notifications to different objects based on the vehicle's security level, further improving the efficiency and accuracy of handling missing component events.

[0119] exist Figure 4 In the method described, after the emergency power supply receives an indication of a missing primary power source from the vehicle, it treats that primary power source as the missing component and supplies power to the vehicle to enable the components within the vehicle to function and transmit communication signals. The emergency power supply then detects the communication signals of the vehicle's components. Components that detect communication signals are considered as not missing, while those that do not are considered as missing. The device information of both the not-missing and missing components is then acquired, and the theft probability of the missing component is calculated based on this information. A missing component alert is then generated and output based on the theft probability. In this way, even when the vehicle's primary power source is missing, other components in the vehicle are also detected for missing components, enabling theft prevention monitoring of vehicle components. Furthermore, obtaining the theft probability of the missing component and outputting the corresponding missing component alert improves the efficiency and accuracy of handling missing component events.

[0120] The above describes the method of the embodiments of the application in detail. The device of the embodiments of the application is provided below.

[0121] Consistent with the embodiments shown in FIG. 1, Figure 3 and Figure 4 Consistent with the embodiments shown in FIG. 1, Figure 2 The emergency power supply is disposed in a vehicle, and the vehicle includes an original power supply and at least two components. The power supply module, the processing module, and the communication module in the emergency power supply are respectively configured to perform the following steps:

[0127] The communication module 2023 outputs a prompt of absence of the first component.

[0128] In one possible example, after the power supply module 2021 supplies power to the vehicle, before the communication module 2023 outputs the prompt of absence of the first component, the processing module 2022 is further configured to perform the following steps:

[0129] Obtain first device information of the first component and second device information of the second component;

[0130] Based on the first device information and the second device information, obtain a probability of theft of the first component;

[0131] Based on the probability of theft of the first component, generate the prompt of absence of the first component.

[0137] obtain a second probability of no damage and loss of the second spare part based on the association relationship;

[0138] calculate the stolen probability of the first spare part based on the first probability and the second probability.

[0140] obtain position information of the vehicle;

[0142] generate the loss prompt of the first spare part based on the loss cause and the position information.

[0143] In a possible example, the communication signal of the second spare part is a first ultra-wideband (UWB) signal, and in the aspect of obtaining the position information of the vehicle, the communication module 2023 is further configured to perform the following steps:

[0144] detect a second UWB signal of a reference device other than the first UWB signal, the second UWB signal carrying a bearing parameter of the reference device;

[0146] obtain position information of the reference device;

[0147] obtain the position information of the vehicle based on the position information of the reference device and the bearing parameter.

[0148] In a possible example, in the aspect of outputting the loss prompt of the first spare part, the processing module 2022 is further configured to perform the following steps:

[0149] determine a prompt object corresponding to the stolen probability of the first spare part;

[0150] The communication module 2023 is further configured to perform the following steps:

[0151] send the loss prompt of the first spare part to the prompt object.

[0152] For detailed execution processes of each module in the emergency power supply 202, please refer to the execution steps in the aforementioned method embodiment, which will not be repeated here.

[0153] Please refer to Figure 5 , Figure 5 This is a structural schematic diagram of a vehicle provided in an embodiment of this application. For example... Figure 5 As shown, the vehicle 50 includes a processor 501, a memory 502, a communication interface 503, an emergency power supply 504, and components 505. The processor 501, memory 502, communication interface 503, emergency power supply 504, and components 505 can be connected via a bus 506.

[0154] Processor 501 executes instructions stored in memory 502 to control communication interface 503 to receive and send signals, thus completing the steps in the above method. Processor 501 may be a central processing unit (CPU), or it may be other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc.

[0155] It should be noted that when the processor 501 is a general-purpose processor, DSP, ASIC, FPGA or other programmable logic device, discrete gate or transistor logic device, or discrete hardware component, the memory 502 (memory module) can be integrated into the processor.

[0156] The memory 502 can also be configured separately from the processor 501. The memory 502 may include a storage system 5021, a cache 5022, and random access memory (RAM) 5023. The cache 5022 is a primary memory located between the RAM 5023 and the CPU, composed of static RAM chips (SRAM). It has a relatively small capacity but a much higher speed than main memory, approaching the speed of the CPU. The RAM 5023 is an internal memory that directly exchanges data with the CPU. It can be read and written at any time (except during refresh) and is very fast, typically serving as temporary data storage for the operating system or other running programs. The three components work together to realize the function of the memory 502.

[0157] The program 5024 stored in the memory 502 is configured to be executed by the processor 501 described above, and the program 5024 is configured to implement the method steps corresponding to the method embodiments described above.

[0161] Output the missing prompt of the first component.

[0162] In a possible example, after powering the vehicle 50, before outputting the missing prompt of the first component, the program 5024 is further configured to execute the instructions of the following steps:

[0163] In response to detecting the communication signal of the other component, the other component is taken as the second component that is not absent;

[0164] Obtain first device information of the first component and second device information of the second component;

[0165] Based on the first device information and the second device information, obtain the probability of theft of the first component;

[0166] Based on the probability of theft of the first component, generate the missing prompt of the first component.

[0167] In a possible example, in terms of obtaining the probability of theft of the first component based on the first device information and the second device information, the program 5024 is specifically configured to execute the instructions of the following steps:

[0168] Based on the first device information and the second device information, obtain the association relationship between the first component and the second component;

[0169] Based on the first device information and the association relationship, obtain the probability of theft of the first component.

[0170] In a possible example, in terms of obtaining the probability of theft of the first component based on the first device information and the association relationship, the program 5024 is specifically configured to execute the instructions of the following steps:

[0171] Based on the first device information, obtain a first probability of damage and absence of the first component;

[0172] Based on the correlation relationship, a second probability of the second component being undamaged and missing is obtained.

[0173] Based on the first probability and the second probability, a stolen probability of the first component is calculated.

[0174] In a possible example, in terms of generating a missing prompt of the first component based on the stolen probability of the first component, the program 5024 is specifically configured to execute the instructions of the following steps:

[0175] Obtain location information of the vehicle 50;

[0176] In response to the stolen probability of the first component being less than a first threshold, it is determined that the missing reason of the first component is equipment damage;

[0177] Generate a missing prompt of the first component based on the missing reason and the location information.

[0178] Alternatively, in a possible example, after obtaining the location information of the vehicle 50, before generating the missing prompt of the first component based on the missing reason and the location information, the program 5024 is further configured to execute the instructions of the following steps:

[0179] In response to the stolen probability of the first component being greater than or equal to the first threshold, it is determined that the missing reason of the first component is illegal disassembly.

[0180] In a possible example, the communication signal of the second component is a first UWB signal, and in terms of obtaining the location information of the vehicle 50, the program 5024 is specifically configured to execute the instructions of the following steps:

[0181] Detect a second UWB signal of a reference device other than the first UWB signal, the second UWB signal carrying a bearing parameter of the reference device;

[0182] Obtain location information of the reference device;

[0183] Obtain the location information of the vehicle 50 based on the location information and the bearing parameter of the reference device.

[0185] Determine a prompt object corresponding to the stolen probability of the first component;

[0186] Send the missing prompt of the first component to the prompt object.
