Online writing method and system for vehicle configuration information

Abstract

The invention discloses an online writing method for vehicle configuration information, which comprises the following steps of: storing vehicle numbers and configuration information of all vehicles on a server; downloading the vehicle numbers and the configuration information of all vehicles from the server, inputting the vehicle numbers of the vehicles to be configured, searching for the configuration information of the vehicles to be configured according to the input vehicle numbers of the vehicles to be configured, and transmitting the configuration information of the vehicles to be configured to the body controllers of the vehicles to be configured in the form of configuration messages; after the body controllers of the vehicles to be configured receive the configuration messages, setting the configuration information of the vehicles to be configured. The invention additionally discloses an online writing system for vehicle configuration information. The online writing method and the online writing system for vehicle configuration information have the advantages that the operating time of operators can be reduced, and the data accuracy and the configuration efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of automotive electronic control, in particular to a method and system for online flashing of vehicle configuration information. Background technique [0002] With the development of automobile electronics, the number of electronic control units (Electronic Control Unit, ECU) on automobiles is increasing continuously. For example, the number of electronic control units on a high-end car can reach more than 100. In addition, today's society has continuously improved the requirements of automobile performance, such as the improvement of automobile safety, comfort, handling and other performance, which makes the information exchanged between the ECU of the automobile more and more, and the control function of the electronic control unit is complicated. The degree increases. [0003] In order to ensure the factory quality of the whole vehicle, after the assembly of the whole vehicle is completed, it is necessa...

Problems solved by technology

However, the refreshing of the function configuration of the vehicle body controller requires the operator to manually input item by item to the EOL equipment, and select or change on the EOL equipment

The data accuracy of the configuration information entered in this way is not high, it will take a long time, the configuration efficiency is low, and it cannot meet the production cycle of the current production line
