The vehicle diagnosis system in the embodiment of the present application includes a user terminal, a vehicle data server, and an intelligent diagnosis device. Among them, before the intelligent diagnosis device in this embodiment is used by the user, the user may register the basic information of the user terminal and the user's vehicle on the vehicle data server through the user terminal, so that the intelligent diagnosis device can diagnose the user's vehicle before Since the basic information of the user's vehicle is obtained from the vehicle data server, the user terminal in the embodiment of the present application can communicate with the vehicle data server, and the vehicle data server can communicate with the intelligent diagnostic device. In this way, after the diagnosis of the user's vehicle is completed by the intelligent diagnosis device, the diagnosis report can be uploaded to the vehicle data server, and the vehicle data server can push the diagnosis report to the user terminal for the user to view. Figure 1 shows the devices in the vehicle diagnostic system and the communication connection relationship between the devices.

To facilitate understanding, the vehicle diagnosis method in the embodiment of the present application is described below from an interactive perspective. Referring to FIG. 2, an embodiment of the vehicle diagnosis method in the embodiment of the present application includes:

201. When the intelligent diagnostic device detects the access of the user vehicle, the intelligent diagnostic device obtains a unique identification code of the user vehicle;

In practical application scenarios, the intelligent diagnostic device can be fixed in a sealed container, and the sealed container has the functions of waterproof, anti-theft, heat dissipation and moisture resistance, in order to adapt to different outdoor environmental parameters, and the sealed container can be placed in any The place where the vehicle user may use to realize the unattended intelligent diagnosis device and the automatic diagnosis of the vehicle by the intelligent diagnosis device, and the free use of the intelligent diagnosis device by the user; or, the intelligent diagnosis device may also be used in a non-closed container. , Placed in various repair shops, to facilitate professional operators to help users to achieve automated diagnosis of vehicles.

Specifically, since each vehicle has a self-diagnostic OBD system, when the user uses the intelligent diagnostic device to diagnose the user's vehicle, the intelligent diagnostic device and the user's vehicle can be electrically connected. When the intelligent diagnostic device does not have an independent working power source , The user can electrically connect the intelligent diagnostic device with the OBD system of the user's vehicle, thereby obtaining working power from the vehicle's OBD system, and when the intelligent diagnostic device detects the user's vehicle, it can automatically obtain the unique identification code of the user's vehicle, that is, the user Vehicle VIN code or license plate information.

Specifically, when the intelligent diagnosis device detects the user vehicle, the unique identification code of the user vehicle can be read from the OBD system, or when the user vehicle is detected, the vehicle data server sends a dialog prompt message to the user terminal. The user is prompted to enter the unique identification code of the vehicle, and there is no specific limitation on the manner in which the intelligent diagnostic device obtains the unique identification code of the user's vehicle.

202. The intelligent diagnosis device sends a basic information acquisition request of the user vehicle to the vehicle data server according to the unique identification code;

After the intelligent diagnosis device obtains the unique identification code of the vehicle, according to the unique identification code, the basic information acquisition request of the user vehicle is sent to the vehicle data server, so as to determine the system to be diagnosed of the vehicle according to the basic information of the vehicle.

Generally, the engine systems, electronic components and communication interfaces of different brands of vehicles are different, while vehicles of the same brand and model have the same engine system, electronic components and communication interfaces, such as the BMW 540 / 95-97 The 740 uses the M62 engine and M5.2 (Bosch) control system, while the Mercedes-Benz Me9.7 engine uses the ME-SFI electronic control system. Therefore, vehicles of different brands and models have different electronic control systems, and the intelligent diagnostic device needs to be based on each The basic information of each vehicle determines the system to be diagnosed of the vehicle, so as to diagnose the system to be diagnosed of the vehicle.

It is easy to understand that before the intelligent diagnostic device sends the basic information acquisition request of the user vehicle to the vehicle data server, the vehicle data server stores the basic information of the user vehicle in advance, and the vehicle data server may obtain the basic information of the user vehicle as Any of the following:
