[0112] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0113] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0114] Figure 1 A schematic diagram showing a system architecture of an exemplary application environment that can be applied to the vehicle remote diagnosis method according to an embodiment of the present application.

[0115] like Figure 1 As shown, the system architecture 100 may include a remote diagnostic device 101, a cloud server 102, and a vehicle diagnostic device 103. The remote diagnostic device 101 includes but is not limited to a desktop computer, a portable computer, a smart phone, a tablet computer, and the like. The remote diagnostic device 101 may be a device that is far away from the vehicle, and is responsible for sending a vehicle diagnostic request to the cloud server 102 and managing the vehicle diagnostic request. For example, a vehicle diagnostic request is sent to a specified vehicle or a batch of vehicles through the cloud server 102, and the diagnostic result, diagnostic progress, and status information are received. The cloud server 102 serves as a bridge between the remote diagnostic device 101 and the vehicle diagnostic device 103, and completes the data transmission between the remote diagnostic device 101 and the vehicle diagnostic device 103. The vehicle diagnostic device 103 is located in the vehicle, and can diagnose the vehicle and return the diagnostic result to the cloud server 102.

[0116] It should be understood that Figure 1 The number of remote diagnostic devices, cloud servers, and vehicle diagnostic devices is only illustrative. According to the implementation requirements, there can be any number of remote diagnostic devices, cloud servers, and vehicle diagnostic devices. For example, the cloud server 102 can be a server cluster composed of multiple servers.

[0117] The following first introduces the vehicle remote diagnosis method of an embodiment of the present application in detail.

[0118] See also Figure 2 , Figure 2 This is a flow chart of a vehicle remote diagnosis method in an embodiment of the present application, which is applied to a vehicle computer diagnosis device and may include the following steps:

[0119] Step S210 , receiving a vehicle diagnosis request sent by a cloud server, wherein the vehicle diagnosis request is received by the cloud server from a remote diagnosis device.

[0120] In an embodiment of the present application, a diagnostician can initiate a vehicle diagnostic request for a target vehicle in a remote diagnostic device. In some embodiments, the remote diagnostic device can provide an interface for inputting a VIN (Vehicle Identification Number), and the diagnostician can input the vehicle identification code required for diagnosis into the remote diagnostic device and initiate a diagnosis. The remote diagnostic device obtains the input vehicle identification code of the target vehicle, and based on the vehicle identification code, generates a vehicle diagnostic request for the target vehicle, and the vehicle diagnostic request includes the vehicle identification code of the target vehicle. Alternatively, a vehicle identification code list can be directly provided in the remote diagnostic device, and the diagnostician can select a vehicle identification code from the vehicle identification code list and initiate a diagnosis. The remote diagnostic device generates a vehicle diagnostic request for the target vehicle based on the vehicle identification code.

[0121] The remote diagnostic device responds to the vehicle diagnostic request and sends a vehicle diagnostic request to the cloud server. The cloud server can be connected to the vehicle manufacturer's MES (Manufacturing Execution System), and the cloud server can contain multiple databases: DTC (DTC) database, ECU (Electronic Control Unit) database and diagnostic request database. The diagnostic request database is used to store vehicle diagnostic requests, the DTC database is used to store fault codes, and the ECU database is used to store relevant information of the electronic control unit.

[0122] After receiving the vehicle diagnostic request, the cloud server may store the vehicle diagnostic request in the diagnostic request database. In addition, the vehicle diagnostic request is sent to the vehicle diagnostic device corresponding to the vehicle diagnostic request. For example, the cloud server may store a mapping relationship between the vehicle identification code and the device identification code of the vehicle diagnostic device, obtain the corresponding device identification code of the vehicle diagnostic device according to the mapping relationship and the vehicle identification code in the vehicle diagnostic request, and send the vehicle diagnostic request to the vehicle diagnostic device based on the device identification code of the vehicle diagnostic device.

[0123] Step S220, determining whether the network status of the vehicle where the vehicle diagnostic device is located meets the preset network condition.

[0124] After the vehicle diagnostic device receives the vehicle diagnostic request, it can first determine whether the network status of the vehicle where the vehicle diagnostic device is located meets the preset network conditions. If the network status of the vehicle where the vehicle diagnostic device is located meets the preset network conditions, execute step S230; if the network status of the vehicle where the vehicle diagnostic device is located does not meet the preset network conditions, execute step S240.

[0125] In order to avoid errors when the cloud server sends a vehicle diagnostic request, after receiving the vehicle diagnostic request, the vehicle diagnostic device can determine whether the vehicle diagnostic request is a vehicle diagnostic request for the vehicle where the vehicle diagnostic device is located. If the vehicle diagnostic request is a vehicle diagnostic request for the vehicle where the vehicle diagnostic device is located, it is then determined whether the network status of the vehicle where the vehicle diagnostic device is located meets the preset network conditions.

[0126] Optionally, the vehicle diagnostic device can obtain the first vehicle identification code in the vehicle diagnostic request and the second vehicle identification code of the vehicle where the vehicle diagnostic device is located. If the first vehicle identification code is the same as the second vehicle identification code, it is determined that the vehicle diagnostic request is a vehicle diagnostic request for the vehicle where the vehicle diagnostic device is located. If the first vehicle identification code is different from the second vehicle identification code, it is determined that the vehicle diagnostic request is not a vehicle diagnostic request for the vehicle where the vehicle diagnostic device is located. At this time, the vehicle diagnostic device can return a prompt message of "vehicle diagnostic request sending error" to the cloud server so that the cloud server resends the correct vehicle diagnostic request.

[0127] Step S230, diagnose the vehicle where the vehicle diagnostic device is located, obtain and return the diagnostic result.

[0128] If the network status of the vehicle where the vehicle diagnostic device is located meets the preset network conditions, the target vehicle can be diagnosed. During the diagnostic process, the screen of the vehicle diagnostic device can light up and display a prompt message "Remote diagnosis in progress", and then the entire vehicle enters the diagnostic phase. After the diagnosis is completed and the diagnostic results are obtained, the diagnostic results are sent to the cloud server. After the cloud server receives the diagnostic results, it can send the diagnostic results to the remote diagnostic device. In this way, the diagnostic personnel can directly view the diagnostic results of the target vehicle on the remote diagnostic device. It can be understood that the number of target vehicles can be multiple, that is, the diagnostic personnel can initiate vehicle diagnostic requests for multiple vehicles at the same time, and the vehicle diagnostic devices on multiple vehicles can diagnose multiple vehicles separately. It can be seen that the embodiment of the present application can diagnose multiple vehicles in batches in parallel, thereby improving the efficiency of vehicle diagnosis.

[0129] In some embodiments, when the vehicle diagnostic device diagnoses the vehicle, the whole vehicle mode can be diagnosed first. Specifically, the whole vehicle mode of the vehicle where the vehicle diagnostic device is located can be obtained. If the whole vehicle mode is an abnormal mode, the mode of the electronic control unit of the vehicle where the vehicle diagnostic device is located is switched to a normal mode to make the whole vehicle mode a normal mode. For example, each electronic control unit in the vehicle can be controlled to enter the normal mode in sequence through a script. Afterwards, the electronic control unit of the vehicle where the vehicle diagnostic device is located is diagnosed to obtain a diagnostic result. If the whole vehicle mode is a normal mode, the electronic control unit of the vehicle where the vehicle diagnostic device is located can be directly diagnosed to obtain a diagnostic result.

[0130] If the diagnosis results of each electronic control unit are all that there is no fault, the diagnosis result is passed, and the diagnosis result of "diagnosis passed" is returned to the cloud server. If at least one electronic control unit has a fault, the fault code of the faulty electronic control unit is compared with the locally stored release fault code. If the fault code of at least one faulty electronic control unit is not included in the release fault code, it is determined that the diagnosis has failed, and a diagnosis result of "diagnosis failed" can be returned to the cloud server. The diagnosis result may include the reason for the diagnosis failure. If the fault codes of all faulty electronic control units are included in the release fault code, a diagnosis result of "diagnosis passed" can be returned to the cloud server. After the diagnosis is completed, the vehicle can be automatically shut down and powered off, and the vehicle status information is returned at the same time. The vehicle status information includes: power, tire pressure, GPS (Global Positioning System) location information, etc.

[0131] It should be noted that the release fault code refers to a fault code that can be released even though the fault exists. The release fault code may include: a fault code corresponding to a false alarm caused by external conditions, etc. For example, in summer, the temperature of the electronic control unit is too high due to overheating in the weather. The fault code in this scenario is a release fault code.

[0132] Optionally, before obtaining the whole vehicle mode of the vehicle where the vehicle diagnostic device is located, it can be determined whether the vehicle where the vehicle diagnostic device is located meets the pre-diagnosis conditions, wherein the pre-diagnosis conditions are used to characterize the overall state of the vehicle where the vehicle diagnostic device is located. In other words, first determine whether the vehicle where the vehicle diagnostic device is located meets a certain normal state. If the vehicle where the vehicle diagnostic device is located meets the pre-diagnosis conditions, it means that the vehicle meets a certain normal state, and the step of obtaining the whole vehicle mode of the vehicle where the vehicle diagnostic device is located is executed to further diagnose the vehicle. If the vehicle where the vehicle diagnostic device is located does not meet the pre-diagnosis conditions, it means that the vehicle does not meet a certain normal state, and it is determined that the vehicle where the vehicle diagnostic device is located has a fault. In some embodiments, the pre-diagnosis conditions can be referred to Table 1.

[0133] Table 1

[0134] serial number project Pre-diagnostic conditions X1 Vehicle speed V km / h V＝0 X2 Power ＞10％ X3 Oil quantity ＞5L X4 Network Status Good signal X5 Vehicle displacement (GPS) Vehicle displacement < 0 X6 Vehicle door lock status All vehicle locked X7 Special conditions Unlocked Vehicle

[0135] The different numbers in Table 1 correspond to the pre-diagnostic conditions of different items. For extended-range vehicles, the oil level and power status can be considered, for pure electric vehicles only need to consider the power level, and for pure oil vehicles only need to consider the oil level.

[0136] Optionally, the result of whether the pre-diagnosis condition is met can be expressed as Xi, if Xi = 0, it means that the pre-diagnosis condition is met, if Xi = 1, it means that the pre-diagnosis condition is not met. ∑Xi = 0, it is determined that the vehicle meets the pre-diagnosis condition; if ∑Xi> 0, it is determined that the vehicle does not meet the pre-diagnosis condition.

[0137] Step S240 , returning failure information, so that the remote diagnostic device resends a first preset number of vehicle diagnostic requests after receiving the failure information.

[0138] If the current network status does not meet the preset network conditions, a failure message is sent to the cloud server, for example, a "request failed" message can be sent. The cloud server forwards the failure message to the remote diagnostic device, and the remote diagnostic device can send a first preset number (for example, 3) of vehicle diagnostic requests. Optionally, the first preset number of vehicle diagnostic requests can be sent periodically within a preset time period, for example, once every 2 seconds within 1 minute. Alternatively, the first preset number of vehicle diagnostic requests can also be sent continuously. In this way, the vehicle diagnostic device re-receives each vehicle diagnostic request and re-executes the above process. When the subsequent network status meets the preset network conditions, the vehicle can be diagnosed to obtain and return the diagnostic results.

[0139] In the vehicle remote diagnosis method of the embodiment of the present application, after the vehicle diagnostic device receives the vehicle diagnostic request, it first determines whether the network status of the vehicle where the vehicle diagnostic device is located meets the preset network conditions. If the preset network conditions are met, the target vehicle is diagnosed to obtain and return the diagnostic results. The cloud server further sends the diagnostic results to the remote diagnostic device, so that the diagnostic personnel can directly view the diagnostic results through the remote diagnostic device. If the preset network conditions are not met, a failure message is returned. After receiving the failure message, the remote diagnostic device can resend a preset number of vehicle diagnostic requests. In this way, when the subsequent network status meets the preset network conditions, the vehicle diagnostic device diagnoses the vehicle based on the re-received vehicle diagnostic request and obtains the diagnostic results. The remote diagnostic device can receive the diagnostic results, thereby improving the success rate of obtaining the vehicle diagnostic results.

[0140] In some embodiments, after re-receiving a first preset number of vehicle diagnostic requests forwarded by the cloud server, if the network status of the vehicle where the vehicle diagnostic device is located meets the preset network conditions, the vehicle where the vehicle diagnostic device is located is diagnosed to obtain and return the diagnostic results.

[0141] If the network status of the vehicle where the vehicle diagnostic device is located still does not meet the preset network conditions, a failure message is returned so that the remote diagnostic device can send a network switching instruction after receiving the failure message. The vehicle diagnostic device receives the network switching instruction forwarded by the cloud server, switches the network of the vehicle diagnostic device, and returns a switching success message after the switching is completed, so that the remote diagnostic device can resend the second preset number of vehicle diagnostic requests after receiving the switching success message. That is, the network status is changed by switching the network to improve the success rate of obtaining the diagnostic result.

[0142] After re-receiving the second preset number of vehicle diagnostic requests forwarded by the cloud server, if the network status of the vehicle where the vehicle diagnostic device is located meets the preset network conditions, the vehicle where the vehicle diagnostic device is located is diagnosed, and the diagnostic results are obtained and returned; if the network status of the vehicle where the vehicle diagnostic device is located still does not meet the preset network conditions, the diagnosis of the vehicle where the vehicle diagnostic device is located is terminated to prevent the vehicle from frequent power consumption.

[0143] See also Figure 3 , Figure 3 This is another flow chart of the vehicle remote diagnosis method in the embodiment of the present application, which is applied to a cloud server and may include the following steps:

[0144] Step S310: receiving a vehicle diagnosis request sent by a remote diagnosis device.

[0145] Step S320, sending a vehicle diagnostic request to the vehicle diagnostic device corresponding to the vehicle diagnostic request, so that the vehicle diagnostic device determines whether the network status of the vehicle where the vehicle diagnostic device is located meets the preset network conditions; if the network status of the vehicle where the vehicle diagnostic device is located meets the preset network conditions, diagnose the vehicle where the vehicle diagnostic device is located, obtain and return the diagnostic results; if the network status of the vehicle where the vehicle diagnostic device is located does not meet the preset network conditions, return failure information.

[0146] Step S330, if a diagnosis result is received, sending the diagnosis result to a remote diagnosis device;

[0147] Step S340: If failure information is received, the failure information is sent to the remote diagnostic device so that the remote diagnostic device resends a first preset number of vehicle diagnostic requests.

[0148] In the vehicle remote diagnosis method of the embodiment of the present application, the diagnostic personnel can initiate a vehicle diagnosis request to the target vehicle through the remote diagnostic equipment, and the cloud server forwards the vehicle diagnosis request to the corresponding vehicle diagnostic equipment. The vehicle diagnostic equipment can first determine whether the network status of the vehicle where the vehicle diagnostic equipment is located meets the preset network conditions. If the preset network conditions are met, the vehicle is diagnosed to obtain and return the diagnosis results. If the preset network conditions are not met, a failure message is returned. After receiving the failure message, the remote diagnostic equipment can resend a preset number of vehicle diagnostic requests. In this way, when the subsequent network status meets the preset network conditions, the vehicle diagnostic equipment diagnoses the vehicle based on the re-received vehicle diagnostic request and obtains the diagnosis results, and the remote diagnostic equipment can receive the diagnosis results, thereby improving the success rate of obtaining the vehicle diagnosis results.

[0149] In some embodiments, before sending a vehicle diagnostic request to a vehicle diagnostic device corresponding to the vehicle diagnostic request, the cloud server may receive vehicle parameters for the vehicle in which the vehicle diagnostic device is located, sent by each vehicle diagnostic device. According to the vehicle parameters, a diagnostic system matching the vehicle in which the vehicle diagnostic device is located is sent to the vehicle diagnostic device, so that the vehicle diagnostic system diagnoses the vehicle in which the vehicle diagnostic device is located based on the diagnostic system.

[0150] The vehicle diagnostic device can capture the vehicle parameters of the vehicle where the vehicle diagnostic device is located, such as the parameters of various hardware and software in the vehicle, and send the vehicle parameters to the cloud server. The cloud server locally stores the mapping relationship between vehicle parameters and diagnostic systems. Based on the mapping relationship, the diagnostic system that matches the vehicle parameters can be sent to the vehicle diagnostic device. The vehicle diagnostic system can diagnose the vehicle where the vehicle diagnostic device is located based on the diagnostic system, thereby improving the adaptability of vehicle remote diagnosis.

[0151] See also Figure 4 , Figure 4 This is another flow chart of the vehicle remote diagnosis method in the embodiment of the present application, which is applied to a remote diagnosis device and may include the following steps:

[0152] Step S410, in response to a vehicle diagnosis request for a target vehicle, sending a vehicle diagnosis request to a cloud server, so that the cloud server sends the vehicle diagnosis request to a vehicle diagnostic device corresponding to the vehicle diagnosis request, and then the vehicle diagnostic device determines whether the network status of the vehicle where the vehicle diagnostic device is located meets the preset network condition; if the network status of the vehicle where the vehicle diagnostic device is located meets the preset network condition, diagnose the vehicle where the vehicle diagnostic device is located, obtain and return the diagnosis result; if the network status of the vehicle where the vehicle diagnostic device is located does not meet the preset network condition, return failure information;

[0153] Step S420, receiving the diagnosis result sent by the cloud server.

[0154] Step S430, receiving failure information sent by the cloud server, and resending a first preset number of vehicle diagnosis requests to the cloud server.

[0155] In some embodiments, there are multiple target vehicles. After sending a vehicle diagnosis request to the cloud server, the remote diagnosis device may also periodically poll the cloud server to send a diagnosis result acquisition request for multiple target vehicles. For any target vehicle, after receiving the diagnosis result for the target vehicle, stop sending the diagnosis result acquisition request for the target vehicle; or, for any target vehicle, after not receiving the diagnosis result for the target vehicle after a preset time period, stop sending the diagnosis result acquisition request for the target vehicle, and determine that the diagnosis of the target vehicle is abnormal.

[0156] During the diagnostic process, the remote diagnostic device can periodically initiate polling requests for the diagnostic results of multiple vehicles, that is, periodically inquire whether the vehicle diagnostic device in each vehicle has completed the diagnosis and obtained the diagnostic results. For example, a polling request can be initiated every 10 seconds until the diagnostic results are obtained. If the vehicle diagnostic device in a certain vehicle has returned the diagnostic results, the remote diagnostic device will no longer poll the vehicle diagnostic device until the vehicle diagnostic devices in all vehicles return the diagnostic results. It should be noted that after a preset time period (for example, 10 minutes), if the vehicle diagnostic device in one or several vehicles has not responded to the diagnostic results, the polling request for the diagnostic results can be stopped, and the diagnostic abnormality can be displayed to avoid frequently sending vehicle diagnostic requests.
