摘　　要：更新的汽车数据包需要通过相应的刷写设备将数据写入电子控制单元ECU中。使其能更有效地控制汽车中的这些系统单元。由于市面上的车型和ECU型号种类繁多,使得进行汽车的ECU刷写成本高昂。本文设计一种通用型的刷写方法,通过配置车型的XML数据库,开发C程序调用对应车型的数据库和数据包实现刷写功能,针对大容量的刷写数据包提高刷写速度,解决了各类车型的刷写,同时降低了开发成本。The updated car data package needs to be written into the electronic control unit through the corresponding reprogramming device. It makes it possible to control these system units in the car more effectively. Due to the wide variety of vehicle models and ECU models on the market,the cost of reprogramming ECU for automobiles is high. a reprogramming method for general vehicles is designed in this paper. The vehicle model’s XML database is configured.,The database and data package of the corresponding vehicle model is used in the C program to realize the reprogramming function,and improves the reprogramming speed for the large-capacity data package,and solves the reprogramming of the class vehicle models. the development cost can be reduced.
