Problems solved by technology

[0004] Although the traditional car diagnosis method can realize the detection of the car state, for the car owner, the car must be driven to a specific service organization to obtain clear diagnosis information, and it is impossible to know the state of the car anytime and anywhere
Furthermore, because the car owner cannot know the state of the car in time, in many cases, he will not take the initiative to drive the car to the car service agency for fault diagnosis; When the car cannot be used normally, the owner will send the car to the car service agency for diagnosis, which will cause hidden dangers to driving safety and vehicle maintenance

Embodiment 1

[0087] This embodiment describes the automobile diagnosis method provided by the application from the perspective of the diagnosis server, see Figure 1b As shown, the method includes:

[0088] Step S1: The diagnostic server remotely receives the fault code sent by the terminal on the vehicle side;

[0089] In a specific embodiment of the present application, the vehicle-side terminal may be a diagnostic terminal installed inside the vehicle, and the diagnostic terminal has the function of remote communication with a diagnostic server on the network side; on the other hand, the diagnostic terminal It can obtain the status data inside the car from the ECU, and judge whether the car is currently faulty according to whether the status data contains a fault code. If it is determined that the car is currently faulty, the fault code will be sent to the diagnostic server on the network side.

[0090] In another specific embodiment of the present application, the terminal on the vehi...

Embodiment 2

[0102] Embodiment 2 of the present application provides another automobile diagnosis method, which is a preferred embodiment of the automobile diagnosis method provided by the present application; specifically, the method mainly includes a mobile device, a diagnosis terminal, and a diagnosis server information interaction process, see figure 2 As shown, the method includes:

[0103] Step 201: Establish a connection between the mobile device and the diagnosis terminal;

[0104] The diagnostic terminal is installed in the car and connected with the electronic control unit ECU in the car;

[0105] The mobile device is owned by the car owner and can be a smart phone, tablet computer, notebook computer and other devices;

[0106] The mobile device and the diagnostic terminal can communicate and handshake through Bluetooth, WIFI wireless local area network or network cable direct connection. If the handshake is successful, the connection will be established. If the handshake is u...

Embodiment 3

[0138] Embodiment 2 of the present application provides another automobile diagnosis method, which is another preferred embodiment of the automobile diagnosis method provided by the present application; the method mainly includes the information interaction process between the diagnosis terminal and the diagnosis server, and the mobile The device serves as a display platform for diagnostic results; see image 3 , the method includes:

[0139] Step 301: The diagnostic terminal and the diagnostic server perform communication authentication, and if the authentication succeeds, the communication starts, and step 302 is executed, and if the authentication fails, the current program ends;

[0140] The diagnostic terminal and the diagnostic server are remotely connected through wireless means;

[0141] Step 302: The diagnosis terminal acquires the status data of the vehicle in the ECU;

[0142] The diagnostic terminal is installed in the car and connected with the electronic contro...

Abstract

The invention relates to an automobile diagnosis method, server and system. The automobile diagnosis method comprises the following steps that: a diagnosis server receives a fault code sent by an automotive side terminal remotely and records a sending equipment identifier; the received fault code is analyzed to obtain a fault diagnosis result; according to the sending equipment identifier, the fault diagnosis result is pushed to a corresponding automobile owner. According to the technical scheme, the automobile owner can timely obtain an automobile fault situation without the need to drive the automobile to a specific maintenance site and then decides whether the maintenance needs to be carried out based on the obtained fault situation. Therefore, the unnecessary time wasting can be reduced; the automatable potential safety hazard can be effectively reduced; and the accident occurrence probability can also be reduced.

Description

technical field [0001] The present application relates to the field of Internet application technology, and in particular to a method, server and system for automobile diagnosis. Background technique [0002] Automobile diagnosis refers to the detection of various parts of the car without dismantling or disassembling the car, and further analysis of the cause of the fault when the faulty part is detected; common car diagnostic items include diagnosing the car body , Diagnose the engine, diagnose the exhaust pollutants and noise of the car, and so on. [0003] The electronic control unit ECU installed in the car generally has a fault diagnosis function, which is used to detect the working status of each part of the car; when a fault is detected in a certain part of the car, a fault code is generated according to the fault type, and the fault code is stored In the random access memory RAM of the ECU; according to the traditional car diagnosis method, if the car owner wants to...
