Method and device for automatically generating variables based on SHELL script

Abstract

The invention provides a method for automatically generating variables based on a SHELL script. The method comprises the steps of establishing a configuration file with a preset name in a preset route, orderly writing variables in the configuration files according to a predetermined criteria, translating the configuration file by virtue of the SHEEL script according to a predetermined criteria so as to generate a first file and a second file, and integrating upper-layer software, bottom-layer software, the first file and the second file according to Makefile so as to obtain a target file, wherein the upper-layer software and bottom-layer software are capable of obtaining variables from the target files so as to invoke the variables. The method is capable of improving the development efficiency of software and thus increasing the debugging and loading progress of an ECU (Electronic Control Unit).

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a method and device for automatically generating variables based on a SHELL script. Background technique [0002] In the current field of automotive electronic control software development, the general development method is matlab for strategy software development, and various debugging software for bottom-level software development. Strategy development and bottom-level development are carried out on their own independent development platforms, and the two modules interact through global variables. . Global variables are often defined by one party and used by the other party after declaration. The two modules are often developed by different people. If the communication is not timely, it is easy to generate errors of undefined variables or repeated definitions of variables when integrating links. Affect the integration progress of the integrators, resulting in...

Problems solved by technology

At present, the more commonly used method is to define variables at the bottom layer, and declare the variable attributes before use at the upper layer. When the number of projects gradually increases, the variables to be used will increase in units of hundreds. At the same time, once the variables need to be adjusted during the development process At the same time, the upper layer and the lower layer need to be modified synchronously. Once the upper layer and the lower layer are inconsistent, it will lead to undefined or repeated definitions of variables during integration.

At this time, manual debugging is required, which consumes too much time and affects the normal use of the ECU.
