The following explains the vehicle diagnosis method provided in the embodiment of the present application in detail. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.

Referring to fig. 3, which is a flowchart illustrating a first vehicle diagnosis method provided in an embodiment of the present application, applied to a cloud server, in a possible embodiment, referring to fig. 3, the vehicle diagnosis method includes the following steps.

S201, a diagnosis instruction sent by a user is received, and the diagnosis instruction is used for requesting to diagnose a target vehicle.

The diagnosis instruction refers to a diagnosis command corresponding to a specific diagnosis function item. The target vehicle is a vehicle to be detected corresponding to a diagnosis instruction sent by a user.

In practical application, the diagnosis instruction sent by the user and received by the cloud server can be sent to the cloud server by the user through a webpage platform corresponding to the vehicle diagnosis service on the client; or the user sends the vehicle diagnosis service to the cloud server through application software which is installed on the terminal equipment and corresponds to the vehicle diagnosis service.

S202, sending the diagnosis instruction to diagnosis joint equipment bound with a user so that the diagnosis joint equipment diagnoses the target vehicle according to the diagnosis instruction, and the diagnosis joint equipment is in communication connection with the target vehicle.

In this embodiment, the diagnostic adapter device is a device for connecting the target vehicle and the cloud server, and the diagnostic adapter device is a diagnostic adapter device having a binding relationship with a user.

It should be understood that user information is stored in the cloud server, and the user information includes device information of the diagnostic connector device bound to the user account; when the cloud server receives a diagnosis instruction sent by a user, the cloud server searches equipment information of diagnosis joint equipment bound with a user account, and if the user account is not bound with the diagnosis joint equipment, the user is prompted to bind; if the user account number is bound with the corresponding diagnosis joint device, the cloud server sends the received diagnosis instruction to the diagnosis joint device.

In order to improve the experience of the user in using the diagnostic adapter device and prolong the service life of the diagnostic adapter device, optionally, after the user purchases the diagnostic adapter device, the user may obtain an identification code (e.g., a registration code) of the diagnostic adapter device, and before vehicle diagnosis, the user registers and logs in a corresponding client to verify the diagnostic adapter device, and completes the initialization configuration of the diagnostic adapter device. The initialization configuration of the diagnostic adapter equipment comprises firmware upgrading of the diagnostic adapter equipment, binding of the diagnostic adapter equipment and a user account relation and the like.

The communication connection between the diagnostic adapter device and the target vehicle may refer to that the diagnostic adapter device is connected to a diagnostic seat of the target vehicle according to a preset specification requirement, wherein the preset specification requirement includes a connection mode and a corresponding operation flow of the target vehicle and the diagnostic adapter device. And when the target vehicle is started, the diagnosis joint equipment is in communication connection with the target vehicle.

The cloud server receives a diagnosis instruction sent by a user, sends the received diagnosis instruction to the diagnosis joint equipment bound with the user, and the diagnosis joint equipment can diagnose a target vehicle in communication connection with the diagnosis joint equipment according to the diagnosis instruction after receiving the diagnosis instruction. In the embodiment of the application, the diagnosis joint equipment is internally provided with diagnosis software, and when receiving a diagnosis instruction sent by the cloud server, the diagnosis joint equipment starts the diagnosis software and diagnoses a target vehicle according to the diagnosis instruction.

And S203, acquiring the diagnostic data returned by the diagnostic joint equipment, and analyzing the diagnostic data to obtain a diagnostic result.

In the embodiment of the application, in order to accelerate the diagnosis of the target vehicle and shorten the detection time of the target vehicle, after the diagnosis of the target vehicle by the diagnosis joint device is completed, the cloud server acquires the diagnosis data returned by the diagnosis joint device, analyzes and collates the received diagnosis data, and forms the diagnosis result corresponding to the target vehicle.

In order to clearly show the diagnosis of the target vehicle, in one possible embodiment, the diagnosis data is analyzed and collated, and the diagnosis result is formed by using characters, images, graph curves, videos or the like.

And S204, sending the diagnosis result to a user.

In order to facilitate the user to check the vehicle diagnosis result, after the vehicle diagnosis is completed, the cloud server analyzes the diagnosis data returned by the diagnosis joint device, and the formed diagnosis result is sent to the user, so that the user can know the diagnosis result of the target vehicle.

In the vehicle diagnosis method of the embodiment, the cloud server receives a diagnosis instruction sent by a user, and after receiving the diagnosis instruction sent by the user, sends the diagnosis instruction to the diagnosis joint device bound to the user, so that the diagnosis joint device in communication connection with the target vehicle diagnoses the target vehicle according to the diagnosis instruction, and then obtains returned diagnosis data through the diagnosis joint device, and after analyzing the diagnosis data, obtains a diagnosis result and sends the diagnosis result to the user. Compared with the traditional vehicle diagnosis method, the vehicle diagnosis method provided by the application reduces the hardware equipment of the diagnosis equipment, and the vehicle can be diagnosed directly through the diagnosis joint equipment by combining the cloud server, so that the vehicle diagnosis efficiency is greatly improved.

In a possible implementation manner, as shown in fig. 4, which is a flowchart of a second vehicle diagnosis method provided in the embodiments of the present application, referring to fig. 4, before receiving a diagnosis instruction sent by a user, the method further includes steps S200a to S200 c.

S200a, the target diagnostic software for executing the diagnostic instruction is determined according to the received user operation.

In an actual application process, the cloud server may determine target diagnosis software according to an operation (e.g., a selection operation) of a user, where the target diagnosis software is configured to execute a corresponding diagnosis instruction to diagnose a target vehicle.

And S200b, sending a starting instruction to the diagnosis joint device, wherein the starting instruction is used for instructing the diagnosis joint device to start the target diagnosis software.

The method comprises the steps that a user selects corresponding target diagnosis software according to the type of a target vehicle, a cloud server sends a starting instruction for starting the target diagnosis software to diagnosis joint equipment when receiving the selection instruction, and when the diagnosis joint equipment receives the starting instruction for starting the target diagnosis software and the target diagnosis software is downloaded in the diagnosis joint equipment, the corresponding target diagnosis software is directly started, so that the target diagnosis software can diagnose the target vehicle according to subsequent diagnosis instructions.

And S200c, if the starting failure information returned by the diagnostic joint equipment is received, software data of the target diagnostic software is issued to the diagnostic joint equipment.

In this embodiment, after the diagnostic adapter device receives the software start instruction sent by the cloud server, if the target diagnostic software is not downloaded in the diagnostic adapter device, the start failure instruction is fed back to the cloud server, and the cloud server sends software data of the corresponding target diagnostic software to the diagnostic adapter device, so that the diagnostic adapter device installs the target diagnostic software according to the software data.

For example, assuming that the model of the target vehicle is a, the cloud server sends a start instruction for instructing the diagnostic adapter device to start the target diagnostic software a to the diagnostic adapter device, and if the start failure information returned by the diagnostic adapter device is received, and the reason for generating the start failure information is that the corresponding target diagnostic software a does not exist in the diagnostic adapter device, the cloud server issues software data corresponding to the target diagnostic software a to the diagnostic adapter device.

Therefore, the target diagnosis software can be pre-installed in the diagnosis joint device, the target diagnosis software also can not be pre-installed in the diagnosis joint device, if the target diagnosis software is not pre-installed in the diagnosis joint device, the cloud server can send software data corresponding to the target diagnosis software to the diagnosis joint device, and meanwhile, the cloud server can store diagnosis software corresponding to various different vehicle types, so that in the application, the diagnosis joint device does not need to be pre-installed with diagnosis software of various vehicle types, and can be directly downloaded from the cloud server when needed, the memory of the diagnosis joint device is greatly released, and the diagnosis efficiency of the vehicle is further improved.

In another possible embodiment, after sending the activation command to the diagnostic joint device, the method further includes: if a software updating prompt sent by the diagnosis joint equipment is received; and issuing the software updating data of the target diagnostic software to the diagnostic adapter equipment according to the software updating prompt.

In order to reduce the time for downloading the target diagnosis software in the vehicle diagnosis process and improve the vehicle diagnosis efficiency, in the embodiment of the application, when the diagnosis joint device downloads the target diagnosis software and the downloaded target diagnosis software needs to be updated, the diagnosis joint device sends a software update prompt to the cloud server, after the cloud server receives the software update prompt sent by the diagnosis joint device, software update data of the target diagnosis software is sent to the diagnosis joint device according to the software update prompt, and the diagnosis joint device updates the downloaded target diagnosis software according to the received software update data.

For example, assuming that the model of the target vehicle is a, the cloud server sends a start instruction to the diagnostic adapter device to instruct the diagnostic adapter device to start diagnostic software corresponding to the model a with version information of 2.0, and the version information of the diagnostic software stored in the storage space of the diagnostic adapter device is diagnostic software of the model a with version information of 1.0, where the version 2.0 of the diagnostic software of the model a is updated on the basis of the version 1.0, that is, some functions are added, modified or deleted in the diagnostic software to make the operation of the diagnostic software in the diagnostic adapter device more stable, when the diagnostic adapter device receives the start instruction, the version information of the diagnostic software stored in the storage space of the diagnostic adapter device is not consistent with the version information of the diagnostic software in the start instruction, a software update prompt is returned to the cloud server, the cloud server issues software updating data corresponding to the diagnosis software to the diagnosis joint equipment according to the received software updating prompt, and the diagnosis joint equipment updates the diagnosis software with version information of 1.0 version according to the software updating data issued by the cloud server.

In the above example, after the diagnostic adapter device returns the software update prompt, the cloud server issues the software update data of the target diagnostic software to the diagnostic adapter device according to the software update prompt. With the continuous improvement and upgrading of the functions of the diagnostic software, only the information such as the version of the diagnostic software stored in the diagnostic connector equipment needs to be detected in the vehicle diagnostic process, and the diagnostic software is directly updated under the condition that the diagnostic software needs to be updated, so that the time for a user to wait for the downloading of the diagnostic software in the vehicle diagnostic process is effectively reduced. In other words, compared with the method that the cloud server directly issues the updated complete target diagnosis software, namely the target diagnosis software with the latest version, to the diagnosis joint device, the time for downloading the target diagnosis software each time can be saved, and the vehicle diagnosis speed is increased.

In some embodiments, after sending the activation command to the diagnostic adapter device, the method further comprises: if a diagnosis function menu corresponding to the target diagnosis software returned by the diagnosis joint equipment is received; the diagnostic function menu is sent to the user so that the user triggers a diagnostic instruction according to the diagnostic function menu.

Based on the above example, it is assumed that the start instruction sent by the cloud server to the diagnostic adapter device is used to instruct the diagnostic software corresponding to the a vehicle type of which the diagnostic adapter device start version information is 2.0 version, and the version information of the diagnostic software stored in the storage space of the diagnostic adapter device is also the diagnostic software of the a vehicle type of 2.0 version, after the diagnostic adapter device receives the start instruction, the diagnostic function menu corresponding to the diagnostic software is directly returned to the cloud server, and after the cloud server returns the diagnostic function menu corresponding to the diagnostic software to the user, the user can select the corresponding diagnostic function item according to the diagnostic function menu to trigger the diagnostic instruction corresponding to the diagnostic function item. For example, the user may select a diagnostic function item corresponding to the "vehicle rapid test" in the returned diagnostic menu data to trigger a diagnostic instruction corresponding to the diagnostic function item, and the diagnostic adapter device obtains a diagnostic result corresponding to the "vehicle rapid test" function item according to the diagnostic instruction.

In practical application, the same or different diagnostic software can be installed on different diagnostic joint devices, and if the diagnostic joint devices download target diagnostic software corresponding to information such as the type of a target vehicle, the diagnostic joint devices directly return a diagnostic function menu corresponding to the target diagnostic software to the cloud server. After the cloud server receives a diagnosis function menu corresponding to the target diagnosis software returned by the diagnosis joint equipment, the diagnosis joint equipment not only shows that the target diagnosis software is normally started according to the starting instruction, but also can directly use the started target diagnosis software to diagnose the target vehicle; but also that the diagnostic tap device has downloaded and stored the target diagnostic software and that the target diagnostic software does not need to be updated. Thus, when the diagnosis joint device is used for diagnosing other vehicles of the same vehicle type, the vehicle diagnosis time can be further shortened, and the diagnosis efficiency is improved.

In some possible embodiments, before sending the activation instruction to the diagnostic joint device, the method further comprises: judging whether the diagnosis joint equipment is in an online state; if not, informing the diagnosis joint equipment to log in; if yes, the starting instruction is sent to the joint diagnosis equipment and the subsequent steps are executed.

Wherein diagnosing the status of the splice device can include: online, offline, and under diagnosis. For example, when the state of the diagnostic joint device is in an online state, which indicates that the diagnostic joint device is available and idle, the user can use the diagnostic joint device in the online state to diagnose the target vehicle; when the state of the diagnosis joint equipment is an off-line state, the diagnosis joint equipment does not establish communication connection with any vehicle including a target vehicle, and at the moment, a user cannot use the diagnosis joint equipment in the off-line state to diagnose the target vehicle; in the case where the diagnostic joint device in the diagnosing state is diagnosing another vehicle when the state of the diagnostic joint device is the diagnosing state, the user cannot diagnose the target vehicle using the diagnostic joint device in the diagnosing state. Of course, the state of the diagnostic adapter device may also include other states, for example, a state during maintenance or busy, and similarly, the functions of the diagnostic adapter device in different states may also be designed according to different practical application requirements, which is not limited in this application.

It should be noted that notifying the diagnostic adapter device to log in means notifying the diagnostic adapter device to establish a communication link with the target vehicle so that the diagnostic adapter device is online. The method for notifying the diagnostic joint device to log in can be that corresponding notification information is sent to the diagnostic joint device, and the diagnostic joint device displays the notification information on a display screen of the diagnostic joint device after receiving the notification information; or corresponding notification instructions are sent to the diagnostic joint equipment, and after the diagnostic joint equipment receives the notification instructions, corresponding indicator lamps on the diagnostic joint equipment are lightened, namely the lightened indicator lamps are used for prompting the diagnostic joint equipment to log in; the diagnostic joint device can also send a corresponding notification instruction to the diagnostic joint device, and after receiving the notification instruction, the diagnostic joint device triggers a buzzer arranged on the diagnostic joint device to buzz, wherein the buzzing buzzer is used for prompting the diagnostic joint device to log in. The manner in which the diagnostic tap device is notified to log in is not limited in any way.

If the cloud server judges that the diagnosis joint equipment is not in an online state, the diagnosis joint equipment is informed to log in; and if the cloud server judges that the diagnosis joint equipment is in an online state, sending a starting instruction to the diagnosis joint equipment and carrying out the subsequent steps.

Through the embodiment, the situation that diagnosis interruption occurs because the diagnosis joint equipment cannot send the diagnosis instruction to diagnose the vehicle according to the cloud server because the diagnosis joint equipment is not in the online state can be avoided.

Fig. 5 is a flowchart of a third vehicle diagnosis method provided in the embodiment of the present application, and a schematic diagram of interaction between the cloud server and the diagnosis adapter device shown in fig. 6 may be formed with fig. 3, where, referring to fig. 5, the method applied to the diagnosis adapter device includes the following steps S301 to S303.

S301, receiving a diagnosis instruction sent by the cloud server.

The cloud server receives a diagnosis instruction sent by a user, sends the diagnosis instruction to diagnosis joint equipment bound with the user, and diagnoses the target vehicle according to the diagnosis instruction after the diagnosis joint equipment receives the diagnosis instruction.

And S302, diagnosing the target vehicle according to the diagnosis command to obtain diagnosis data corresponding to the target vehicle.

And after the diagnosis joint equipment receives the diagnosis instruction, the diagnosis joint equipment diagnoses the target vehicle by using target diagnosis software corresponding to the diagnosis instruction, and because the diagnosis joint equipment is in communication connection with the target vehicle, corresponding diagnosis data can be obtained according to a message fed back by the target vehicle.

And S303, returning the diagnosis data to the cloud server.

In order to improve the diagnosis efficiency and execution speed of the diagnosis joint device on the target vehicle, after the diagnosis data of the target vehicle are obtained, the diagnosis data are returned to the cloud server, so that the cloud server analyzes the diagnosis data to obtain a diagnosis result. As can be understood, in the case that the diagnostic data amount in the diagnostic result is small, the diagnostic adapter device can also perform simple sorting and analysis on the acquired diagnostic data to reduce the pressure of the cloud server on processing the diagnostic data.

According to the embodiment, the condition that the storage space of the diagnosis joint equipment is smaller and smaller due to the fact that a large amount of data are stored in the diagnosis joint equipment, namely the memory of the diagnosis joint equipment is insufficient is avoided, and the service life of the diagnosis joint equipment is prolonged.

In one embodiment, before receiving the diagnosis instruction sent by the cloud server, the method further includes: receiving a starting instruction sent by a cloud server, wherein the starting instruction is used for indicating to start target diagnosis software for executing a diagnosis instruction; detecting whether the target diagnosis software is downloaded; if not, the starting failure information is returned.

It should be understood that the diagnostic adapter device downloads the target diagnostic software, including the diagnostic adapter device downloads the diagnostic software corresponding to the name, version, etc. of the target diagnostic software, and the user can directly use the downloaded diagnostic software to diagnose the target vehicle. The diagnostic adapter device does not download the target diagnostic software, including but not limited to the diagnostic software corresponding to the name of the target diagnostic software, but the downloaded diagnostic software and the target diagnostic software have differences in function or configuration information and the like.

The cloud server determines target diagnosis software for executing a diagnosis instruction according to received user operation, and then sends a starting instruction to the diagnosis joint device, the diagnosis joint device detects whether corresponding target diagnosis software is downloaded in the diagnosis joint device after receiving the starting instruction, if the diagnosis joint device downloads the target diagnosis software, the diagnosis instruction sent by the cloud server can be directly received, and then the target vehicle is diagnosed by the target diagnosis software according to the diagnosis instruction; if the diagnosis joint equipment does not download the target diagnosis software, starting failure information needs to be returned to the cloud server, and the starting failure information is used for triggering the cloud server to issue software data corresponding to the target diagnosis software to the diagnosis joint equipment.

According to the embodiment, after the starting instruction sent by the cloud server is received, if the diagnosis joint device detects that the target diagnosis software is downloaded, the target diagnosis software can be directly started, the target diagnosis software is directly used for diagnosing the target vehicle, so that a user can conveniently and directly send the diagnosis instruction to diagnose the target vehicle, the speed of diagnosing the target vehicle is increased, and the diagnosis of the target vehicle can be completed in a short time.

Of course, to improve the universality of the diagnostic junction device, the diagnostic software stored in the diagnostic junction device may be deleted after each vehicle diagnosis is completed according to the actual application requirements.

As can be easily understood, because the diagnostic adapter device can store diagnostic software corresponding to different target vehicles, along with the increasing of the number of the diagnostic software and the updating data of the diagnostic software, the storage space in the diagnostic adapter device is smaller and smaller, and in order to ensure that the diagnostic adapter device has enough storage space to receive the target diagnostic software which is sent by the cloud server and can be applied to different vehicle types, the vehicle diagnostic method provided by the embodiment of the application further includes: the diagnostic tap device detects a stored state of the diagnostic tap device; and when the free storage space of the diagnosis joint device is lower than a preset threshold value, the diagnosis joint device deletes the diagnosis software stored in the diagnosis joint device.

The preset threshold may be a storage space capable of storing the current diagnostic software, and a corresponding value may also be set according to an actual situation. In addition, part or all of the stored diagnostic software can be deleted according to actual requirements, so that enough space is released for storing the diagnostic software sent by the server.

For example, a self-checking module may be disposed in the diagnostic joint device, the self-checking module is configured to detect a storage space of the diagnostic joint device, and delete part or all of the diagnostic software stored in the storage space of the diagnostic joint device when the space of the diagnostic joint device for storing the diagnostic software corresponding to the target vehicle is lower than a preset threshold.

Optionally, after the diagnostic software stored in the storage space of the diagnostic adapter device is deleted, corresponding prompt information may be returned to the cloud server and/or the client to prompt the cloud server and/or the user to delete the diagnostic software stored in the diagnostic adapter device due to the problem of the storage space. The prompt information may not be set, and the diagnostic software may be downloaded according to the vehicle diagnostic method provided by the embodiment of the application again in the subsequent use process of the diagnostic adapter device.
