General calibration system of automobile electronic control unit and realizing method thereof

Abstract

The present invention provides a general calibration system of an automobile electronic control unit and a realizing method thereof, which relates to the field of automobile electronic control. Based on configuration technique, the present invention adopts the idea that interface design is separated from system function design. The calibration system is divided into an editing environment part, an XML (extensive makeup language) configuration project file and a running environment part. The XML configuration project file is used as the middle layer of the calibration system for describing the graphical interface of the whole calibration system with a standard tree-like structure. The editing environment part is used for building a user interface model, making a calibration system interface and producing relative XML configuration project file. An XML file analyzer, data management and kernel communication are encapsulated in the running environment. The running environment part is connected with an electronic control unit (ECU) below, and monitoring and calibration functions are realized. The present invention realizes the interface customer making and reconfiguration of the calibration system, and meets the alteration and updating project requirements of the ECU. Meanwhile, the expandable and cross-platform XML project file can be reused on different operating system platforms, and the general utilization of the calibration system is improved.

Description

technical field [0001] The present invention relates to computer and automatic control technology, especially the field of automotive electronics technology, mainly the general calibration technology of electronic control unit (ECU, Electronic Control Unit) of the vehicle. Background technique [0002] The development of automobile electronics is changing the traditional structure of automobiles and expanding the functions of automobiles. The application of automobile electronics technology is becoming one of the most effective means to compete for the future automobile market. Therefore, there are more and more components with electronic control units (ECUs) in automobiles, such as: engine EFI control, automobile anti-lock braking system, body control system, power management, etc. are all typical applications of automotive ECUs. At the same time, as the function and performance of the electronic control unit continue to increase, the development process of the electronic c...
