Embodiment 1

[0043] An embodiment of the present invention provides a vehicle remote diagnosis system, such as figure 1 As shown, the vehicle remote diagnosis system includes a vehicle-mounted terminal and a remote diagnosis server, and the vehicle-mounted terminal includes a gateway and a T-Box.

[0044]The gateway is used to obtain diagnostic instructions, send diagnostic requests to the controller, and obtain fault information fed back by the controller. The gateway, as a diagnostic terminal, can also store the fault information and send the fault information to the T-Box;

[0045] The T-Box is a data transmission device, which is used to obtain the diagnosis instruction sent by the user and send it to the gateway, and is also used to obtain the fault information from the gateway and send it to the remote diagnosis server, and the fault information is transmitted to the remote diagnosis server through the T-Box. Diagnose the server remotely, or send it to the user.

[0046] A security ...

Embodiment 2

[0061] A feasible embodiment of the present invention provides a method for remote vehicle diagnosis. Such as figure 2 As shown, the method includes:

[0062] S1. The user sends a diagnostic command to the vehicle terminal, and the T-Box on the vehicle terminal obtains the command.

[0063] S2. After the T-Box on the vehicle-mounted terminal and the gateway on the vehicle-mounted terminal pass the security access verification, the gateway obtains a diagnosis instruction.

[0064] S3. The gateway sends a diagnosis request to the designated controller, obtains the fault information fed back by the controller, and sends the fault information to the T-Box.

[0065] S4. T-Box obtains the fault information sent by the gateway, and sends the fault information to the mobile terminal, computer terminal and remote diagnosis server.

[0066] S5. The remote diagnosis server calls the fault repair plan corresponding to the fault information. When there is no corresponding fault repair ...

Abstract

The invention relates to the field of Internet of vehicles and particularly relates to a remote vehicle diagnosis system and method. The remote vehicle diagnosis system comprises a vehicle terminal and a remote diagnosis server, wherein the vehicle terminal comprises a diagnosis request reception unit, a fault information feedback unit, a gateway and a T-Box, the diagnosis request reception unit is used for receiving a diagnosis request, the fault information feedback unit is used for feeding back the fault information, the gateway is used for sending the diagnosis request and acquiring the feedback fault information, and the T-Box is used for transmitting the fault information to the remote diagnosis server. The remote vehicle diagnosis system is advantaged in that the gateway is taken asa diagnosis terminal, the T-Box is taken as a transmitting device, stable operation of the T-Box is guaranteed, safety access verification is added between the T-Box and the gateway, two-way verification through the T-Box and the gateway is respectively carried out when an instruction is externally transmitted, and safety of the whole network is improved.

Description

technical field [0001] The invention relates to the field of Internet of Vehicles, in particular to a vehicle remote diagnosis system and method. Background technique [0002] The car remote fault diagnosis system is a new fault diagnosis method proposed in recent years, which enables the car to send diagnostic fault codes from the electronic control module of the car to an analysis center through a wireless communication connection to realize remote fault diagnosis of the car. The remote fault diagnosis of the car can detect and feed back the status of the vehicle, which is convenient for the maintenance and care of the vehicle. [0003] In the prior art, the entire remote fault diagnosis system includes a VMS vehicle controller and an on-board diagnostic terminal that communicates with the VMS vehicle controller through the CAN bus. Read the fault information collected by the vehicle controller, and feed the fault information to the background monitoring service device th...
