Embodiment 1

[0056] Embodiment one, such as figure 1 As shown, it is a schematic flow chart of a remote transmission method for vehicle-mounted T-box data, and the specific steps are:

[0057] Step 1, switch the car T-box from normal mode to test mode.

[0058] When the whole vehicle breaks down or technicians need to observe the data, turn on the mode switch of the on-board T-box and receive the switching command. At this time, the function of the original T-box in normal mode will be suspended and directly enter the test mode.

[0059] Both the normal mode and the test mode here can be programs written based on code.

[0060] The normal pattern is:

[0061] Such as figure 2 As shown, when the vehicle is started, T-box needs to send part of the data of the vehicle to the cloud server through the network;

[0062] In normal mode, T-box records data through the CAN bus, then sends it to the cloud server through the network, and then uploads it to the platform of each terminal. Therefo...

Abstract

The invention provides a remote transmission method for vehicle-mounted T-box data, a vehicle networking system and a vehicle. The remote transmission method comprises the following steps: receiving a switching instruction; when the T-box is switched from the normal mode to the test mode, the following steps are executed: recording all the whole vehicle data and storing the data in the storage unit; transmitting all the whole vehicle data of the storage unit to a specified storage area of a cloud server for storage; the storage unit is used for storing all the whole vehicle data in a formatting manner before the normal mode is switched to the test mode next time; and when the T-box is switched from the test mode to the normal mode, executing the following steps: acquiring and sending current real-time whole vehicle data to a storage area, different from the specified storage area, of the cloud server so as to confirm the basic state of the whole vehicle. According to the invention, the authenticity of the recorded data can be improved, the integrity of the data can be determined, and the whole vehicle data file of the corresponding period can still be completely transmitted by means of the storage unit under the conditions that the data file is too large and the network signal is not good.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a method for remote transmission of vehicle T-box data. Background technique [0002] With the rapid development of the automobile industry, vehicle testing and vehicle fault handling are becoming more and more important. Various problems will arise in the prototype stage and engineers need to solve them. This process will consume a lot of manpower, material and financial resources. Due to the slow data transmission of the current on-board T-box and frame loss problems during the transmission process, it is difficult for vehicle engineers to obtain all vehicle data and conduct remote analysis and processing of vehicle failures and other issues. Contents of the invention [0003] A main problem solved by the present invention is that the data transmission of the existing vehicle-mounted T-box is relatively slow, and data transmission frames are lost, which makes i...
