It provides fault information about vehicle systems and components by connecting to an Electronic Control Unit (ECU) of the vehicle and reading the fault code of the vehicle, and a full vehicle fault diagnosis system generally comprises the following components: OBD connection interface: an OBD interface for connecting a diagnostic tool or scanner to the vehicle. The OBD interface is typically located under the pedals or under the steering wheel in the cockpit area; diagnostic tool or scanner: for communication with the OBD system of the vehicle and reading fault codes and other relevant real-time data. The diagnostic tool may be a handheld device, a notebook computer, a smart phone, or the like; OBD Electronic Control Unit (ECU): the various systems and components in the vehicle are controlled by an ECU, such as an engine control unit, a transmission control unit, a brake system control unit, and the like. The OBD system is connected to the ECUs and reads fault codes and data stored in the ECUs; fault code database: the diagnostic tool typically provides a database of fault codes for interpreting and identifying the read fault codes. By querying the fault code database, a technician or owner can learn the specific cause and possible repair of the fault.
The existing vehicle diagnosis mode has 2 general modes, namely, the first mode is to carry out real vehicle diagnosis for a special diagnostic instrument tool, and the vehicle fault code is read and displayed on a screen interface of the diagnostic instrument, so that a specific maintenance point is required to be specially searched for and the diagnostic instrument is used for checking, and the convenience is low;
the second type is that the user is connected with the cloud platform through the mobile phone APP to send a diagnosis request to the vehicle remote network terminal equipment, the vehicle diagnosis equipment carries out whole vehicle fault diagnosis and feeds back information to the cloud platform, finally, the fault code is displayed on the mobile phone APP of the user through the cloud platform, if the user is in an off-road environment, in a garage or in other environments with poor network signals, the situation that the mobile phone APP cannot send the diagnosis request to the cloud platform exists, and the diagnosis function cannot be used can occur.
Disclosure of Invention

In order to achieve the above purpose, the present invention provides the following technical solutions: a full vehicle fault diagnosis system based on a vehicle cloud integration technology comprises a TBOX vehicle networking equipment terminal, an IVI vehicle-mounted entertainment host, an ECU module and a cloud service platform.
As a preferred implementation manner, the TBOX internet of vehicles device terminal extracts various data of the ECU module and uploads the data to the cloud service platform.
As a preferred embodiment, the cloud service platform issues a diagnosis request to the IVI vehicle-mounted entertainment host according to the ECU module fault identification bit.
As a preferred embodiment, the IVI on-board entertainment host computer prompts the customer whether the vehicle is abnormal or not according to the diagnosis content issued.
As a preferred embodiment, the customer may operate the IVI on-board entertainment host to click on a diagnostic full vehicle request into the diagnostic interface.
As a preferred embodiment, the IVI on-board entertainment host diagnoses the corresponding fault module through the DoIP ethernet communication diagnostic or the UDS vehicle CAN communication diagnostic protocol.
As a preferred implementation manner, the IVI vehicle-mounted entertainment host displays fault contents fed back by the corresponding modules to clients through an interface and prompts corresponding processing measures.
As a preferred implementation mode, the user also directly enters the IVI vehicle-mounted entertainment host machine, requests the IVI vehicle-mounted entertainment host machine to diagnose the whole vehicle through keys, and displays the diagnosis result on the screen interface of the IVI vehicle-mounted entertainment host machine.
Compared with the prior art, the invention has the beneficial effects that:
1. the IVI vehicle-mounted entertainment host replaces an independent diagnostic instrument, so that the equipment cost for producing the independent diagnostic instrument can be greatly reduced, and the economy is realized;
2. the invention can realize the function of monitoring the vehicle fault data at the cloud end, has convenience for after-sale quality analysis of a host factory, can customize whether to push fault diagnosis notification to a user at the background, has more flexibility, and is more humanized in service;
the IVI vehicle-mounted entertainment host replaces an independent diagnostic instrument, can diagnose the whole vehicle under the condition of no network, displays a diagnosis result, has the capability of diagnosing faults of the whole vehicle under the condition of no network compared with the invention of diagnosing the whole vehicle based on the mobile phone APP, and provides help for users to self-check the fault vehicle under the special network-free environment;
4. when the vehicle breaks down, the user can diagnose the whole vehicle in time through the IVI vehicle-mounted entertainment host and obtain maintenance or inspection suggestions, and the safety of the user in using the vehicle can be greatly improved.
In summary, compared with the first scheme in the background art, the vehicle-cloud integrated technology-based whole vehicle fault diagnosis system has the advantages that a user does not need to specially find a specific maintenance point to use a diagnosis tool for troubleshooting when a vehicle breaks down, and the problem can be primarily identified; compared with the second scheme in the background art, the system scheme for diagnosing the whole vehicle fault based on the vehicle cloud integration technology can meet the requirement that the user can diagnose the fault of the whole vehicle only through the IVI vehicle entertainment host computer even under the condition of no network at all, and overcomes the defect that the function can be realized only through a mobile phone network or a TBOX network if the user is in an environment with poor cross country, garage or other network signals and the mobile phone APP cannot send a diagnosis request to the cloud platform, so that the diagnosis function cannot be used.
