[0077] Step 101: Create a communication channel connecting the first vehicle through a wireless network.

[0078] Step 102: Obtain the vehicle configuration information of the first vehicle according to the communication channel.

[0079] Further, in the embodiment of the present invention, obtaining the vehicle configuration information of the first vehicle according to the communication channel is specifically:

[0080] Obtain the vehicle identification code of the first vehicle according to the communication channel;

[0081] Obtain the vehicle configuration information of the first vehicle by identifying the vehicle identification code.

[0082] In the embodiment of the present invention, the vehicle identification code of the first vehicle can be obtained through the communication channel, and the vehicle configuration information of the first vehicle can be obtained by identifying the vehicle identification code. Specifically, a scanning camera can be used to scan the vehicle identification code (VIN) to quickly obtain the vehicle configuration information of the first vehicle, thereby improving the convenience of vehicle information acquisition.

[0083] Step 103: Generate a number of vehicle detection items according to the vehicle configuration information.

[0084] Further, in the embodiment of the present invention, generating a number of vehicle detection items according to the vehicle configuration information is specifically:

[0085] Identify a number of systems of the first vehicle and the configuration information corresponding to each of the systems according to the vehicle configuration information;

[0086] Determine the detection data corresponding to each of the systems according to the configuration information corresponding to each of the systems;

[0087] Generate vehicle inspection items corresponding to each of the systems based on the detection data corresponding to each of the systems.

[0088] In the embodiment of the present invention, according to the vehicle configuration information, a plurality of systems of the first vehicle and the configuration information corresponding to each system can be identified. According to the configuration information corresponding to each system, the detection data required for fault detection of each system can be determined. Based on each detection data, vehicle inspection items corresponding to each system can be generated, thereby providing a detection basis for fault detection and further improving the comprehensiveness of fault detection.

[0089] As an example of the real-time example of the present invention, the systems of the first vehicle include a battery system, a motor system, a transmission system, a safety system, a vehicle control system, and other systems.

[0093] In an embodiment of the present invention, according to each vehicle detection item, the first vehicle can be controlled to enter different working states, and when the first vehicle is in different working states, the state information corresponding to each vehicle detection item is collected. The state information in multiple different states corresponding to the same vehicle detection item is integrated into vehicle state information, providing a diverse data basis for fault detection, thereby improving the accuracy of fault detection.

[0094] As an example of an embodiment of the present invention, the first vehicle is controlled to enter different working states, such as a stationary state, a charging state, a low-speed state, a high-speed state, a bad-road driving state, a wading driving state, etc. In different working states, the state information corresponding to each detection item is collected multiple times. Integrating the state information in different working states can form the vehicle state information corresponding to the detection item.

[0095] Step 107: According to a plurality of the vehicle detection items, obtain the detection rules corresponding to the plurality of the vehicle detection items in a preset rule library.

[0096] Further, in an embodiment of the present invention, according to a plurality of the vehicle detection items, obtaining the detection rules corresponding to the plurality of the vehicle detection items in a preset rule library is specifically as follows:

[0098] According to a plurality of the detection experiments, obtain a plurality of fault analysis rules corresponding to the plurality of the detection experiments in a preset rule library;

[0099] Based on the detection experiments corresponding to a plurality of the vehicle detection items and the fault analysis rules corresponding to the plurality of the detection data, generate the detection rules corresponding to the plurality of the vehicle detection items.

[0100] In an embodiment of the present invention, obtain the detection experiments corresponding to each vehicle detection item in a preset rule library, and obtain the fault analysis rules corresponding to different detection experiments in a preset rule library. According to the determined detection experiments and fault analysis rules, the detection rules corresponding to each vehicle detection item can be generated. Providing specific detection rules for different vehicle detection items can improve the accuracy of the detection rules, thereby improving the accuracy of fault detection.

[0101] Step 108: Based on a plurality of the detection rules and a plurality of the vehicle state information, perform vehicle fault detection to generate a fault detection result.

[0102] Further, in an embodiment of the present invention, based on a plurality of the detection rules and a plurality of the vehicle state information, performing vehicle fault detection to generate a fault detection result is specifically as follows:

[0103] According to a number of detection experiments and a number of vehicle status information, vehicle fault detection is respectively carried out to obtain a number of detection data results;

[0104] Based on a number of the fault analysis rules, the fault level of each of the detection data results is judged to generate fault detection results corresponding to a number of vehicle detection items.

[0105] In the embodiment of the present invention, according to the detection experiment and vehicle status information, vehicle fault detection of different vehicle detection items can be carried out, so as to obtain a plurality of detection data results. Based on the fault analysis rules, the fault level of each detection data result can be judged, so as to obtain the fault detection result. Fault detection is respectively carried out on different vehicle detection items, so as to obtain a comprehensive fault detection result, which can improve the comprehensiveness of fault analysis.

[0106] As an example of the embodiment of the present invention, based on each fault analysis rule, it can be judged whether the first vehicle has a fault, and the fault information is classified. Among them, the fault level can be set to low level, medium level and high level. A low-level fault refers to an occasional unqualified data stream. For example, during the detection of motor parameters, a certain parameter is read 200 times, and no more than 10 times are unqualified. And this fault is displayed on the device and is determined by the on-site engineer to be an occasional data error and has no impact on the whole vehicle, then it is determined that this fault is a low-level fault. A medium-level fault refers to the number of faults exceeding 10 times, that is, there are a small number of unqualified or fault situations in the detection data results, or a fault that can be directly judged such as the headlights not being on. A high-level fault refers to a fault in which, according to the fault analysis rule, there are a large number of unqualified or fault situations in the detection data results, and the specific fault content cannot be intuitively judged.

[0107] Further, in the embodiment of the present invention, referring to Figure 2 , which is a schematic flow chart of another embodiment of the vehicle fault detection method provided by the present invention, this method further includes step 109:

[0108] Step 109: Upload the fault detection result to the maintenance server so that the maintenance server generates a maintenance suggestion according to the fault detection result.

[0109] In the embodiment of the present invention, after the fault detection result is obtained, it is uploaded to the maintenance server, so that the maintenance server generates a maintenance suggestion according to the fault detection result, so that relevant personnel can perform corresponding maintenance operations on the first vehicle, thereby improving the safety of the first vehicle.

[0110] As an example of an embodiment of the present invention, when the fault detection result is a low-level fault, it is uploaded to the maintenance server, and the maintenance server does not perform a repair and return process. When the fault detection result is a medium-level fault, the fault content is displayed, the first vehicle is controlled to perform a locking operation, it is determined that the first vehicle needs to be repaired and returned, and the fault detection result is uploaded to the maintenance server so that the maintenance server records the fault data. When the fault detection result is a high-level fault, the fault content is displayed, the first vehicle is controlled to perform a locking operation, it is determined that the first vehicle needs to be repaired and returned, and the fault detection result is uploaded to the maintenance server so that the maintenance server analyzes the fault cause based on the fault detection result and provides a repair and return suggestion. By generating corresponding repair suggestions for the first vehicle through the maintenance server, unqualified vehicles can be effectively intercepted and prevented from entering the market.

[0111] In an embodiment of the present invention, the fault problem can be quickly determined according to the fault detection result, and repair guidance is provided, thereby improving the on-site repair and return efficiency. When the vehicle needs to be repaired and returned and then undergoes fault detection again, after passing the detection, the fault vehicle is unbound.

[0112] In summary, the embodiment of the present invention provides an automobile fault detection method. A communication channel connecting the first vehicle is created through a wireless network. After the communication channel is established, the vehicle configuration information of the first vehicle can be obtained, improving the efficiency of information acquisition; multiple automobile detection items that need to be subjected to fault detection can be generated according to the vehicle configuration information. According to these automobile detection items, the first vehicle can be controlled to enter different working states respectively, and the state information corresponding to each automobile detection item is collected when the first vehicle is in different working states. The state information under multiple different states corresponding to the same automobile detection item is integrated into automobile state information, providing a diverse data basis for fault detection, and further improving the accuracy of fault detection; according to these automobile detection items, the detection rules corresponding to each automobile detection item can be obtained in a preset rule library; the automobile state information and the detection rules are corresponded one by one, and then comprehensive automobile fault detection can be performed to obtain the fault detection result, so as to achieve comprehensive fault detection of the first vehicle and improve the comprehensiveness and efficiency of fault detection.
