The vehicle described above may be any vehicle equipped with a remote diagnosis technology and an integrated domain controller, and in this embodiment, the type of vehicle is not particularly limited. The diagnostic device may be a diagnostic device in a vehicle, or may be a terminal remotely connected to the vehicle, for example, and may include, but is not limited to: cell phone, tablet computer and personal computer. The above-mentioned diagnostic messages are used for diagnosing and monitoring various systems and components of a vehicle, wherein the diagnostic messages generally contain information about the address information of an engine, a transmission system, a brake system, a vehicle body control system, diagnostic equipment, and address information of a domain controller of the vehicle, such as sensor data, fault codes, system states, and the like. The diagnostic messages can be read and analyzed by a diagnostic scanning tool or diagnostic equipment to help vehicle service personnel to quickly and accurately diagnose and resolve vehicle faults. In this embodiment, the diagnostic message is used to diagnose the integrated domain controller of the vehicle to determine whether the domain controller has a fault.

For example, in the case that the DoIP gateway receives a diagnostic message sent by a diagnostic device, the diagnostic message may be sent to the diagnostic agent dynamic library, the diagnostic agent dynamic library may determine whether the content of the diagnostic message is complete, and whether diagnostic information in the diagnostic message matches the domain controller, in the case that it is determined that the diagnostic message is complete and that the diagnostic information matches the domain controller, the diagnostic message may be returned to the DoIP gateway, the DoIP gateway forwards the diagnostic message to the matching domain controller, and in the case that it is determined that the diagnostic message is incomplete or does not match the domain controller, a value (for example, but not limited to, may be 1) may be returned, indicating to the DoIP gateway that the diagnostic message has been intercepted and needs to be reacquired.
For another example, in the case that the DoIP gateway receives a plurality of diagnostic messages sent by a plurality of diagnostic devices, the DoIP gateway may upload the plurality of diagnostic messages to the diagnostic agent dynamic library, and the diagnostic agent dynamic library may firstly determine a plurality of domain controllers matched with the plurality of diagnostic devices based on a preset diagnostic relationship, and secondly parse the plurality of diagnostic messages, for example, may determine whether the plurality of diagnostic messages are complete, and whether the content of the plurality of diagnostic messages matches with the matched domain controllers, and in the case that it is determined that the plurality of diagnostic messages are complete, and the content of the plurality of diagnostic messages matches with the matched domain controllers, may return the plurality of diagnostic messages to the DoIP gateway, and forward the plurality of diagnostic messages to the plurality of domain controllers matched with the plurality of diagnostic devices by the DoIP gateway.
It should be noted that, the diagnostic agent dynamic library is used for controlling the Doip gateway, and screening and controlling the diagnostic message sent by the diagnostic device to the domain controller by the Doip gateway, so as to realize the technical scheme that multiple application programs diagnose multiple domain controllers simultaneously. It should be noted that the above-mentioned pre-established diagnostic relationship is used to determine the domain controller to which the diagnostic device matches.
And step S106, processing the matched domain controllers based on the diagnosis message to obtain a processing result, wherein the processing result is used for representing whether the matched domain controllers have faults or not.
In an alternative embodiment, after the domain controller receives the matched diagnosis message, the matched domain controller may be processed based on the diagnosis message, for example, performance of the domain controller may be detected, and service status and storage status of the domain controller may be detected, so as to determine whether the performance, service status and storage status of the domain controller are abnormal, and further help a vehicle maintenance personnel to quickly and accurately diagnose and solve a vehicle fault.

It is easy to notice that by determining the domain controller matched with at least one diagnostic device, the technical effect that the at least one diagnostic device processes the matched domain controller based on the diagnostic message is achieved, the domain controller does not need to be processed sequentially by the diagnostic device, and the purpose of efficiently processing a plurality of domain controllers is achieved, so that the technical effect of improving the processing efficiency of the plurality of domain controllers is achieved, and the technical problem that the processing efficiency of the plurality of domain controllers of the vehicle in the related art is low is solved.
Optionally, before determining a domain controller matched with at least one diagnostic device among the plurality of domain controllers of the vehicle based on the diagnosed message, the method further comprises: reading a preset diagnosis relation, wherein the diagnosis relation is used for determining at least one domain controller matched with at least one diagnosis device; based on the diagnostic relationship, controlling at least one diagnostic device to send diagnostic messages to the matched domain controller.
The above-mentioned preset diagnosis relation may be set in advance by a user, and is used for determining different domain controllers matched with different diagnosis devices.
In an alternative embodiment, after the diagnostic message sent by at least one diagnostic device of the vehicle is acquired, firstly, a preset diagnostic relationship can be read through a diagnostic agent dynamic library to determine at least one domain controller matched with the at least one diagnostic device, and secondly, the diagnostic agent dynamic library can control the Doip gateway to forward the diagnostic message sent by the at least one diagnostic device to the domain controller matched with the diagnostic message based on the diagnostic relationship.

The diagnostic information may be a historical diagnostic result of the domain controller, wherein the diagnostic information may include, but is not limited to: event log: the event log of the domain controller records various events and error information of the system, and can help an administrator to know the running condition and the failure cause of the system. And (3) performance monitoring: the performance monitoring tool may help an administrator monitor system resource utilization of the domain controller, such as central processing unit (Central Processing Unit, CPU) utilization, memory usage, disk Input/Output (IO), etc., to discover system performance problems in time. Network connection state: an administrator needs to check the network connection status of the domain controller, including network bandwidth utilization, connection speed, network delay, etc., to ensure that the network communication of the system is normal. Service state: the administrator needs to check the status of various services running on the domain controller, such as domain services, domain name resolution system (Domain Name System, DNS) services, dynamic host configuration protocol (Dynamic Host Configuration Protocol, DHCP) services, etc., to ensure that these services are functioning properly.

Through the inspection and analysis of the diagnosis information, an administrator can timely find out the problem of the domain controller and take corresponding measures to repair the problem so as to ensure the stability and the reliability of the system.
In an alternative embodiment, after the diagnostic agent dynamic library receives the diagnostic message sent by the Doip gateway, it may first determine whether the diagnostic message is complete, and whether diagnostic information in the diagnostic message is matched with a domain controller in the plurality of domain controllers, where the domain controller may be determined to be matched with the diagnostic device if the diagnostic message is complete and the diagnostic information in the diagnostic message is matched with the domain controller, and where the diagnostic message is incomplete or the diagnostic information in the diagnostic message is not matched with the domain controller, it may be determined that the domain controller is not matched with the diagnostic device. For example, in the case where address information of the diagnostic device or the domain controller is absent from the diagnostic message, or diagnostic information of other domain controllers is present in the diagnostic message, it may be determined that the diagnostic message is incomplete, and at this time, it may be determined that the domain controller does not match the diagnostic device.

For example, the performance of the matched domain controller may be detected, so as to obtain a processing result of whether the performance of the domain controller fails.
Optionally, obtaining a diagnostic message sent by at least one diagnostic device of the vehicle includes: acquiring a first diagnosis message sent by first diagnosis equipment in a vehicle; acquiring a second diagnosis message sent by second diagnosis equipment remotely connected with the vehicle; and summarizing the first diagnosis message and the second diagnosis message to obtain the diagnosis message.
The first diagnostic device may be a diagnostic device in a vehicle, and the second diagnostic device may be a terminal device remotely connected to the vehicle.
In an alternative embodiment, the Doip gateway may receive a first diagnostic message sent by a first diagnostic device in the vehicle, and may also receive a second diagnostic message sent by a second diagnostic device remotely connected to the vehicle, and aggregate the first diagnostic message and the second diagnostic message to obtain the diagnostic message.
Optionally, the diagnostic message includes at least one of: IP address, diagnostic information, and diagnostic services.
In an alternative embodiment, to enable accurate fault diagnosis of a domain controller matched to a diagnostic device, the diagnostic message may include, but is not limited to: the domain controller's internet protocol (Internet Protocol, IP) address information, the diagnostic device's IP address information, diagnostic information, and diagnostic services.

As can be seen from fig. 2, the diagnostic device 21 is connected to the DoIP gateway 23, the DoIP gateway 23 is connected to the diagnostic device 21, the diagnostic agent dynamic library 22, and the domain controller 24, the diagnostic agent dynamic library 22 is connected to the DoIP gateway 23, and the domain controller 24 is connected to the DoIP gateway 23.
As can be seen from fig. 2, when the diagnostic device 21 wants to diagnose the domain controller 24 of the vehicle, a diagnostic message may be sent to the DoIP gateway 23 first, after the DoIP gateway 23 receives the diagnostic message, the diagnostic message may be sent to the diagnostic agent dynamic library 22, the diagnostic agent dynamic library 22 determines whether the received diagnostic message is complete and whether the diagnostic message matches the domain controller through the diagnostic relationship, and when it is determined that the diagnostic message is complete and matches the domain controller, the diagnostic message may be returned to the DoIP gateway 23, and the DoIP gateway 23 forwards the diagnostic message to the matched domain controller 24, so that fault diagnosis may be performed on the domain controller through the diagnostic message.
The invention realizes the technical proposal that a plurality of diagnostic devices diagnose a plurality of domain controllers simultaneously by designing the diagnostic agent dynamic library, controlling the Doip gateway through the diagnostic agent dynamic library and screening the messages sent to the domain controllers by the diagnostic devices. The diagnostic agent dynamic library (so) is placed on a designated path to realize the functions of initializing, initializing and reporting diagnostic messages to an interface; the diagnostic agent dynamic library provides a diagnostic message reporting interface for the Doip gateway to send diagnostic messages, the Doip gateway can send all the diagnostic messages to the diagnostic agent dynamic library, and the diagnostic agent dynamic library uses a return value to indicate whether the diagnostic messages are intercepted or not, or the Doip gateway continues to forward the diagnostic messages; the diagnosis agent dynamic library can send diagnosis message through callback interface of the Doip gateway.

The diagnostic agent dynamic library realizes that different diagnostic devices can diagnose different domain controllers simultaneously through the original diagnostic device address information and the destination controller (namely the domain controllers matched with the diagnostic devices) address information in the diagnostic information carried by the diagnostic message. For example, the diagnostic device can diagnose the domain controller 1 at the same time, and the remote diagnostic device can diagnose the domain controller 2 at the same time, so that the diagnostic device is not required to diagnose the domain controller 2 after diagnosis is completed.
