A method and system for vehicle data transmission

Abstract

The embodiment of the invention provides a vehicle data transmission method and a system. The method comprises the following steps: obtaining a target data set aimed at a target functional system; Analyzing each target network data, obtaining the target sampling time point of each target network data; judging whether each target sampling time point is the current sampling time point; If yes, all the target network data in the target data set are packaged and the packaged target information is sent to the target control node, so that the target control node performs corresponding function control according to the target information; if not, caching the target sampling time point as the target network data of the current sampling time point, and updating the target network data which is notthe current sampling point, and judging whether each target sampling time point is the current sampling time point. When the method provided by the embodiment of the invention is used for data transmission, the problem that the functional effect is reduced due to network data asynchronization is avoided.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a vehicle data transmission method and system. Background technique [0002] With the rapid development of automotive electronic product technology, the intelligence of the vehicle has been greatly improved, and the process of realizing the intelligence of the vehicle often requires the use of network data in the vehicle network. [0003] Let’s take the air-conditioning control system of the whole vehicle as an example. In order to collect the temperature information of multiple areas in the vehicle interior, multiple temperature sensors are often arranged on the vehicle, and they can publish the collected temperature information to the network bus; The air-conditioning controller in the air-conditioning control system can obtain various temperature information from the network bus, and then perform temperature control according to the obtained temperature information. ...
