specific Embodiment approach
[0035] The specific operation steps on the production line are as follows:
[0036] 1. Connect the device diagnostic interface with the on-board diagnostic interface online;
[0037] 2. Turn the key to IGN ON to supply power to the vehicle;
[0038] 3. The operator uses a code scanning gun to scan the barcode of the on-board configuration barcode;
[0039] 4. The diagnostic related commands sent by the online configuration device are written into the configuration information;
[0040] 5. Unplug the diagnostic connector, turn off the ignition key, and complete the configuration.
[0041] The online configuration information method of the controller is quick in process, simple in operation, less prone to errors and good in scalability, and is very suitable for mass production of vehicles in workshops.

The invention relates to an online configuration method of an automobile controller, comprising the following steps of: 1, assembling an automobile to a working position of online configuration equipment, electrifying the whole automobile; 2, scanning a vehicular bar code and storing the contents of the bar code by the online configuration equipment so as to obtain configuration information of each controller system of the assembled automobile; 3, establishing communication with each controller by the online configuration equipment, entering a default diagnosis mode of the controllers; 4, entering an EOL (end of life) diagnosis mode of the controllers; verifying safety of each controller; 5, entering the next step if each controller passes the safety verification, quitting from the communication with the controller by the online configuration equipment if each controller fails in the safety verification, reporting errors; 6, performing a data writing operation step of the previous scanned information of configuring the bar code for the controller by the online configuration equipment when the safety verification in step (5) succeeds: finishing the configuration process of the controller if the data are written successfully, providing an error prompt and performing the configuration process of a next controller if the data are written unsuccessfully; 7, storing configuration information of the controller written successfully in step (6); and 8, reading the configuration information of the controller after finishing configuration, comparing the configuration information of the controller with the written configuration information, checking whether the written configuration information is correct, if yes, finishing online configuration, and otherwise, promoting diagnosis communication and reporting the errors.
Description
technical field [0001] The invention relates to the field of automobile automation, mainly manifested in the aspect of online configuration of automobile production lines, and specifically relates to a method for online configuration of automobile controllers. Background technique [0002] With the rapid development of automobile technology, people have higher and higher requirements for the comfort of the whole vehicle. The number of controllers for each system of the automobile has grown from a few to dozens, distributed in the body system, chassis system, power system, etc. in each system. [0003] For the same model, there will be different electrical configurations of high, medium and low grades to adapt to different consumer groups. If the main engine factory develops different controllers for different electrical configurations, it will inevitably lead to unfavorable factors such as increased costs, waste of resources, excessive part numbers and increased management ...
