[0026] Please refer to Figure 1, which shows a vehicle identification method provided by an embodiment of the present application. In a specific embodiment, the vehicle identification method can be applied to a vehicle identification device 600 as shown in Figure 7 and an electronic device 700 (Figure 8) equipped with the vehicle identification device 600. The specific process of this embodiment will be described below. Of course, it can be understood that the method can be executed by a cloud server with computing and processing capabilities. The process shown in Figure 1 will be described in detail below, and may include the following steps:

[0027] Step 110: Determine the power distribution circuit and bus circuit corresponding to the controller of the vehicle according to the configuration information of the vehicle.

[0028] As a method, different vehicles have different configurations, and the configurations of the same vehicle model are also different. Different configurations correspond to different controllers, so that the functions of the corresponding configurations can be realized through the controllers. The difference in the controllers will affect the current allocated by the central controller to each controller and the sending of the network message corresponding to the controller. Therefore, the configuration information of the vehicle can be obtained first, so that the controller corresponding to the vehicle can be determined, and then the power distribution circuit and bus circuit corresponding to the controller can be determined. Optionally, the configuration information of the vehicle can be obtained according to the vehicle identification number (VIN) of the vehicle. The VIN consists of 17 characters and is the unique identification information of the vehicle. The VIN can be used to trace the original information of the vehicle, such as checking the configuration, accessories, recalls, etc. It can also be used for vehicle management and illegal inquiries, such as tracing smuggled cars and stolen cars, and for checking maintenance records and insurance claims records to track historical vehicle conditions. For example, the maintenance, insurance, mileage information of a used car can be queried through the VIN. Optionally, the configuration information corresponding to the VIN can be obtained in the cloud according to the VIN of the vehicle.

[0029] Optionally, each controller corresponds to a power distribution circuit and a bus circuit, the power distribution circuit is used to supply power and protect the controller, and the bus circuit is used to forward and receive network messages corresponding to the controller.

[0030] Optionally, a power distribution module, a routing management module, and a remote upload module may be provided in the vehicle, as shown in FIG2 , wherein the power distribution module is used to implement the power supply and protection functions of the low-voltage power supply in the vehicle. In the embodiment of the present application, the power distribution module has an intelligent power distribution function, which intelligently distributes power and performs power distribution protection through the power distribution controller, abandoning the traditional hard-wired fuse, and is capable of monitoring the voltage and current values ​​of the distribution circuits corresponding to each controller. The routing management module is used to forward and manage network messages corresponding to bus circuits corresponding to multiple controllers. For example, bus messages on bus circuit 1 must be forwarded to bus circuit 2 through the routing management module to achieve forwarding and distribution. The remote upload module is used to upload relevant information of the vehicle to the cloud. For example, before the vehicle leaves the factory, the vehicle configuration information is uploaded to the cloud through the remote upload module.

[0031] In some embodiments, step 110 includes: performing fault detection on the vehicle to determine the fault type of the vehicle; if the fault type is a vehicle power supply fault, obtaining configuration information of the vehicle.

[0032] As a way, since the vehicle is added or modified, the corresponding controller may not be able to sleep normally or the corresponding power consumption may increase, which may lead to a power supply failure of the entire vehicle. Therefore, in order to quickly check whether the vehicle is modified or added, the vehicle can be checked for faults according to a preset cycle to determine whether the vehicle has a fault, and when it is determined that the vehicle has a fault, determine whether the fault type is a power supply failure of the entire vehicle, and then obtain the vehicle configuration information when the vehicle power supply fails, and identify whether the vehicle has been added or modified based on the configuration information.

[0033] Please continue to refer to FIG. 1 , step 120 , determining the current current value corresponding to the power distribution circuit and the current network message corresponding to the bus circuit.

[0034] As one approach, the vehicle's central controller can be used to obtain, in real time, the current current values ​​corresponding to each of the multiple power distribution circuits, as well as the network messages corresponding to each of the multiple bus circuits. Optionally, a power distribution module can be deployed in the vehicle's central controller to allocate the required power to the power distribution circuit corresponding to each controller. Therefore, the power distribution module can be used to obtain, in real time, the current current values ​​corresponding to each power distribution circuit.

[0035] Optionally, a routing management module is deployed in the vehicle's central controller to manage the network messages sent by multiple bus loops of the vehicle. Therefore, the routing management module can be used to obtain the current network messages corresponding to each of the multiple bus loops in real time.

[0036] Step 130, compare the current current value corresponding to the distribution circuit with the standard current value corresponding to the distribution circuit, and / or compare the current network message corresponding to the bus circuit with the standard network message corresponding to the bus circuit, to obtain an identification result of the vehicle, wherein the identification result is used to characterize whether the vehicle has been added or modified, wherein the standard current value is the current value corresponding to the distribution circuit determined before the vehicle leaves the factory, and the standard network message is the network message corresponding to the bus circuit determined before the vehicle leaves the factory.

[0037] As one approach, before a vehicle leaves the factory, the standard current values ​​corresponding to each of the vehicle's multiple power distribution circuits and the standard network messages corresponding to each of the multiple bus circuits can be pre-determined, and these values ​​can be uploaded to the cloud. This facilitates obtaining these values ​​from the cloud. Optionally, the standard current values ​​corresponding to the vehicle's multiple power distribution circuits and the standard network messages corresponding to the multiple bus circuits can be associated and stored with the vehicle's vehicle identification code to generate a standard data table, as shown in Table 1. This allows the vehicle's configuration information to be obtained based on the vehicle identification code, while also obtaining the standard current values ​​corresponding to the vehicle's multiple power distribution circuits and the standard network messages corresponding to the multiple bus circuits.

[0038] Table 1 Standard data sheet of vehicles

[0039] In Table 1, the standard network messages corresponding to the multiple bus loops include the node addresses of the nodes in each bus loop (i.e., the IDs in Table 1), and the node cycles of the nodes in each bus loop (i.e., the cycles in Table 1). The node cycles may be the cycles for each node to send node messages.

[0040] Optionally, the current current values ​​corresponding to each of the multiple distribution circuits are compared with the standard current values ​​corresponding to each of the multiple distribution circuits. The current current values ​​corresponding to each of the multiple distribution circuits can be added to the standard data table for comparison. Similarly, the current network messages corresponding to each of the multiple bus circuits are compared with the standard network messages corresponding to each of the multiple bus circuits. The current network messages corresponding to each of the multiple bus circuits can be added to the standard data table for comparison, as shown in Table 2.

[0041] Table 2 Vehicle data comparison table

[0042] Table 2 includes timestamps of the current current values ​​corresponding to multiple distribution circuits and the current network messages corresponding to multiple bus circuits, so that the current current values ​​corresponding to multiple distribution circuits and the standard current values ​​corresponding to multiple distribution circuits can be quickly compared, and / or the current network messages corresponding to multiple bus circuits and the standard network messages corresponding to multiple bus circuits can be compared to obtain identification results.

[0043] Optionally, the identification result may include determining that the vehicle has been added / modified and determining that the vehicle has not been added / modified. Optionally, if the comparison result is that the current current values ​​corresponding to each of the multiple distribution circuits are equal to the standard current values ​​corresponding to each of the multiple distribution circuits, and / or the current network messages corresponding to each of the multiple bus circuits are the same as the standard network messages corresponding to each of the multiple bus circuits, then the identification result may be determined to be determining that the vehicle has not been added / modified; if the comparison result is that the current current values ​​corresponding to each of the multiple distribution circuits are not equal to the standard current values ​​corresponding to each of the multiple distribution circuits, or the current network messages corresponding to each of the multiple bus circuits are not the same as the standard network messages corresponding to each of the multiple bus circuits, then the identification result may be determined to be determining that the vehicle has been added / modified.

[0044] In an embodiment of the present application, the power distribution circuit and bus circuit corresponding to the vehicle's controller are determined by the vehicle's configuration information, thereby determining the current current value of the power distribution circuit and the current network message of the bus circuit, and then, comparing the current current value corresponding to the power distribution circuit with the standard current value of the power distribution circuit, and / or comparing the current network message corresponding to the bus circuit with the standard network message of the bus circuit, and determining whether the vehicle has been added or modified based on the comparison result. The solution of the present application can determine whether the vehicle has been added or modified by monitoring the power distribution circuit and bus circuit of the vehicle without adding hardware, thereby quickly identifying whether the vehicle has been added or modified, and determining by comparing with the standard current value or standard network message, thereby improving the accuracy of identification.

[0045] Please refer to Figure 3, which shows a vehicle identification method provided by an embodiment of the present application. The following will be a detailed description of the process shown in Figure 3, which may include the following steps:

[0046] Step 210: Determine the power distribution circuit and bus circuit corresponding to the vehicle controller according to the vehicle configuration information.

[0047] Step 220: Determine the current value corresponding to the power distribution circuit and the current network message corresponding to the bus circuit.

[0048] Step 230, compare the current current value corresponding to the distribution circuit with the standard current value corresponding to the distribution circuit, and / or compare the current network message corresponding to the bus circuit with the standard network message corresponding to the bus circuit to obtain an identification result of the vehicle, wherein the identification result is used to characterize whether the vehicle has been added or modified, wherein the standard current value is the current value corresponding to the distribution circuit determined before the vehicle leaves the factory, and the standard network message is the network message corresponding to the bus circuit determined before the vehicle leaves the factory.

[0049] The specific descriptions of steps 210 to 230 may refer to steps 110 to 130 and will not be repeated here.

[0050] Step 240: If it is determined that the vehicle has been added or modified, the current network message corresponding to the added or modified bus loop is determined as the target network message, and the signal address in the target network message is determined.

[0051] As a method, since the network messages corresponding to each of the multiple bus loops may include the signal addresses of the nodes in each bus loop, the functions or electronic devices corresponding to each node can be determined based on the signal addresses of each node. Therefore, when it is determined that the vehicle has been added or modified, the network messages different from the corresponding standard network messages in the network messages corresponding to each of the multiple bus loops are determined as target network messages, and the signal addresses corresponding to each node are determined in the target network messages.

[0052] Step 250: parse the signal address to determine the electronic device corresponding to the signal address.

[0053] As one approach, after determining the signal address of a node in a target network message, the signal address of each node in the standard network message corresponding to the target network message can be compared to determine a newly added signal address, thereby enabling the newly added signal address to be parsed. Optionally, the signal address can be compared with a preset signal address to determine the electronic device corresponding to the signal address. The preset signal address can be the signal address of an electronic device with the same address on different vehicles. For example, the same Bluetooth device has the same signal address on different vehicles, thereby determining the electronic device corresponding to the signal address.

[0054] Step 260 : Positioning the electronic device where the device is installed or modified according to the signal address to obtain the installation or modification location of the electronic device, and generating installation or modification prompt information according to the installation or modification location.

[0055] As a method, after determining the electronic device corresponding to the signal address, in order to enable vehicle maintenance personnel or vehicle owners to quickly detect vehicle failures caused by installations or modifications, the electronic device can be located based on the signal address. This is optional. The signal address can include the controller to which the electronic device is connected, thereby determining the power distribution circuit to which the signal address is connected. The electronic device can then be located based on the controller and power distribution circuit connected to the electronic device.

[0056] Optionally, the installation location or modification location of the electronic device may include the specific location of the power distribution circuit to which the controller to which the electronic device is connected is connected. Optionally, the installation prompt or modification prompt may be in the form of image information, so that after the installation prompt or modification prompt is generated, the installation prompt or modification prompt is displayed on the vehicle's large screen or an electronic device connected to the vehicle for communication, so as to remind the owner or maintenance personnel of the modification location or installation location where a failure may occur. Optionally, the installation prompt or modification prompt may also be in the form of text displayed in a pop-up window, or in the form of voice prompt, which can be set according to actual needs and is not specifically limited here.

[0057] In this embodiment, when it is determined that the vehicle has been added or modified, the signal address is determined based on the target network message of the bus loop where the addition or modification has occurred, so that the signal address can be parsed to determine the electronic device corresponding to the signal address, and then, the electronic device is located according to the signal address to obtain the addition position or modification position, thereby generating addition prompt information or modification prompt information, quickly prompting the addition or modification of the vehicle, and improving the inspection efficiency.

[0058] Please refer to Figure 4, which shows a vehicle identification method provided by an embodiment of the present application. The following will describe the process shown in Figure 4 in detail. For each bus loop in the multiple bus loops, the following steps may be specifically included:

[0059] Step 310: Determine the power distribution circuit and bus circuit corresponding to the vehicle controller according to the vehicle configuration information.

[0060] Step 320: Determine the current value corresponding to the power distribution circuit and the current network message corresponding to the bus circuit.

[0061] The specific step descriptions of step 310 to step 320 can be found in step 110 to step 120 and will not be repeated here.

[0062] Step 330: Determine a first packet quantity of the current network packets and determine a second packet quantity of the standard network packets.

[0063] As one approach, since each controller can have multiple nodes, each implementing different functions, each node sends its own corresponding node message to the bus circuit of the corresponding controller. The corresponding bus circuit generates the current network message based on the node messages received from each node. When a vehicle is modified or equipped with additional equipment, the number of nodes corresponding to the controller increases, and the number of corresponding node messages increases. Therefore, the presence of additional equipment or modifications can be determined by comparing the first message number of the current network message with the second message number of the standard network message.

[0064] Optionally, the number of first messages may be determined by determining the number corresponding to the node ID in the current network message. Similarly, the number of second messages may be determined by determining the number corresponding to the node ID in the standard network message.

[0065] Step 340: If the number of the first messages is the same as the number of the second messages, it is determined that the identification result is that the vehicle has not been added or modified.

[0066] As a method, when it is determined that the number of first messages is the same as the number of second messages, it can be determined that there is no new node in the controller corresponding to the current network message, that is, there is no new electronic device connected to the controller, so the vehicle identification result can be determined that the vehicle has not been added or modified.

[0067] Step 350: If the number of the first messages is different from the number of the second messages, it is determined that the identification result is that the vehicle has been added or modified.

[0068] As a method, when it is determined that the number of first messages is different from the number of second messages, it can be determined that there is a new node in the controller corresponding to the current network message, that is, there is a newly connected electronic device in the controller, so that the vehicle identification result can be determined that the vehicle has been added or modified.

[0069] In some embodiments, after step 320, the method further includes: determining a first sending cycle of the current network message, and determining a second sending cycle of the standard current message; if the first sending cycle is the same as the second sending cycle, determining that the identification result is that the vehicle has not been added or modified; or if the first sending cycle is different from the second sending cycle, determining that the identification result is that the vehicle has been added or modified.

[0070] As one approach, since each controller can contain multiple nodes, each node implementing different functions, each node sends its own corresponding node message to the corresponding controller's bus loop according to its own corresponding period. The corresponding bus loop generates the current network message based on the node messages received from each node. When a vehicle is modified or equipped with an additional device, the period of the newly added node in the controller may differ from the period of other nodes, thereby causing the transmission period of the current network message sent by the controller's corresponding bus loop to change. Therefore, the presence of an additional device or modification can be determined by comparing the first transmission period of the current network message with the second transmission period of the standard network message. For example, a car owner purchases a head unit for a specific vehicle model and replaces the original head unit with another head unit. After the head unit is changed, the period of the bus loop corresponding to the controller where the head unit is located changes. Therefore, the presence of a head unit change can be determined by comparing the first transmission period of the current message of the bus loop corresponding to the controller where the head unit is located with the second transmission period of the standard network message of the bus loop corresponding to the vehicle's factory-maintained head unit stored in the cloud.

[0071] In this embodiment, the first message quantity of the current network message corresponding to each of the multiple bus loops is compared with the second message quantity of the standard network message corresponding to each of the multiple bus loops. In this way, it is determined whether the vehicle has been added or modified based on whether the first message quantity and the second message quantity are the same, thereby improving the efficiency of checking whether the vehicle has been added or modified.

[0072] Please refer to Figure 5, which shows a vehicle identification method provided by an embodiment of the present application. The following will describe in detail the process shown in Figure 5. For each of the multiple power distribution circuits, the following steps may be specifically included:

[0073] Step 410: Determine the power distribution circuit and bus circuit corresponding to the vehicle controller according to the vehicle configuration information.

[0074] Step 420: Determine the current value corresponding to the power distribution circuit and the current network message corresponding to the bus circuit.

[0075] The specific description of steps 410 to 420 can be found in steps 110 to 120 and will not be repeated here.

[0076] Step 430 : Compare the current current value with the standard current value to determine whether the current current value is the same as the standard current value.

[0077] As a way, when a vehicle is modified or added to, the distribution circuit corresponding to the controller at the location of the addition or modification is changed. When there is an addition, a node for distributing electric energy is added to the corresponding distribution circuit, so that the current value corresponding to the distribution circuit increases; if there is a modification, the electric energy distribution of the corresponding distribution circuit changes, which is different from the current value before the modification. Therefore, it is possible to determine whether the vehicle has been added or modified by comparing the current current value corresponding to the distribution circuit and the standard current value corresponding to the distribution circuit.

[0078] Step 440: If the current current value is different from the standard current value, it is determined that the identification result is that the vehicle has been added or modified.

[0079] As a method, when it is determined that the current current value is different from the standard current value, it can be determined that a new node or a node has been changed in the distribution circuit corresponding to the current current value, thereby determining that the vehicle identification result is that the vehicle has been added or modified.

[0080] Step 450: If the current current value is the same as the standard current value, it is determined that the identification result is that the vehicle has not been added or modified.

[0081] As a method, when it is determined that the current current value is the same as the standard current value, it can be determined that the nodes in the distribution circuit corresponding to the current current value have not changed, so that the vehicle identification result can be determined that the vehicle has been added or modified.

[0082] In this embodiment, the current current values ​​corresponding to each of the multiple distribution circuits are compared with the standard current values ​​corresponding to each of the multiple distribution circuits, so as to determine whether the vehicle has been added or modified based on whether the current current value is the same as the standard current value, thereby improving the efficiency of checking whether the vehicle has been added or modified.

[0083] Please refer to Figure 6, which shows a vehicle identification method provided by an embodiment of the present application. The following will be a detailed description of the process shown in Figure 6, which may include the following steps:

[0084] Step 510: Determine the power distribution circuit and bus circuit corresponding to the vehicle controller according to the vehicle configuration information.

[0085] Step 520: Determine the current value corresponding to the power distribution circuit and the current network message corresponding to the bus circuit.

[0086] Step 530, compare the current current value corresponding to the distribution circuit with the standard current value corresponding to the distribution circuit, and / or compare the current network message corresponding to the bus circuit with the standard network message corresponding to the bus circuit, to obtain an identification result of the vehicle, wherein the identification result is used to characterize whether the vehicle has been added or modified, wherein the standard current value is the current value corresponding to the distribution circuit determined before the vehicle leaves the factory, and the standard network message is the network message corresponding to the bus circuit determined before the vehicle leaves the factory.

[0087] The specific descriptions of steps 510 to 530 may refer to steps 110 to 130 and will not be repeated here.

[0088] Step 540: If the vehicle is determined to have an additional power distribution circuit based on the comparison between the standard current value and the current current value, the additional power distribution circuit is determined as the target power distribution circuit, and the standard current value corresponding to the target power distribution circuit is determined as the target current value.

[0089] As a way, when the current current value is compared with the standard current value and determined to be different from the standard current value, it can be determined that the vehicle has an additional installation. At this time, in order to avoid the electronic equipment at the installation location not being in sleep mode, which may cause a power supply failure of the entire vehicle, and more seriously damage the vehicle's battery, the electronic equipment at the installation location can be promptly powered off to handle the fault. In this way, the distribution circuit where the additional electronic equipment is located can be determined first, so that it can be handled by controlling the power distribution of the distribution circuit.

[0090] Optionally, after determining the target power distribution circuit, the target current value of the power distribution circuit may be determined based on the circuit identifier of the target power distribution circuit, thereby obtaining the target current value.

[0091] Step 550: Power off the installed electronic products.

[0092] As a method, after determining the target power distribution circuit, the newly added nodes in the target power distribution circuit can be determined, so that the target power distribution circuit can be controlled to not supply power to the newly added nodes, thereby achieving power-off processing for the installed electronic products.

[0093] Step 560: Acquire the real-time current value corresponding to the target power distribution circuit after the power outage, and compare the real-time current value with the target current value to obtain a comparison result.

[0094] As one approach, after powering off the installed electronic product, the real-time current value of the target power distribution circuit after the power outage is determined to be the same as the target current value corresponding to the target power distribution circuit to determine whether the corresponding fault has been repaired. This can also determine whether the vehicle fault was caused by the installation. Optionally, the comparison results include the real-time current value being the same as the target current value and the real-time current value being different from the target current value.

[0095] Step 570: If the comparison result indicates that the real-time current value is equal to the target current value, it is determined that a fault occurs in the target power distribution circuit.

[0096] As a way, when the comparison result indicates that the real-time current value is the same as the target current value, it can be determined that after the installed electronic product is powered off, the nodes in the target distribution circuit are the same as before installation, and their current values ​​are the same as the target current values ​​used as the standard, which can determine that the fault has been restored, and it can be determined that the installed electronic product in the target distribution circuit caused the target distribution circuit to fail.

[0097] In this embodiment, when it is determined that the vehicle has been added based on the standard current value and the current current value, the added distribution circuit is determined as the target distribution circuit, so that the real-time current value of the target distribution circuit is determined after the added electronic product is powered off. The comparison result is determined based on the real-time current value and the target current value of the target distribution circuit, and then whether the target distribution circuit has a fault is determined based on the comparison result, so that faults caused by the vehicle's additions can be quickly checked.
