Embodiment Construction

[0049] The present invention will be further described below with reference to the drawings and embodiments.

[0050] A general automobile code conversion method, the code conversion steps are as follows:

[0051] 1) Establish a work task on the Simulink work platform, which is a function completed by the software code that needs to be converted;

[0052] 2) According to the selected ECU, determine the code content and form under the OSEKOS operating system specification and the AutoSAR driver interface specification, and establish toolboxes respectively;

[0053] 3) Import the software code information to be converted into the S function, which is determined by the toolbox described in step 2);

[0054] 4) Encapsulate the S function in step 3) and encapsulate it into a working module of the Simulink work platform;

[0055] 5) Import the packaged work module in step 4) into the Simulink work platform;

[0056] 6) Under the Simulink work platform, verify the imported work module, if it fai...

Abstract

The invention relates to a general car code conversion method. Based on a general simulation and code generation tool, MATLAB (matrix laboratory), a vehicular operating system model base meeting specifications of OSEK/VDX OS (open systems and their interfaces for the electronics in motor vehicles/vehicle distributed eXecutive operating system) and an underlying drive interface model base meeting standards of AutoSAR (AUTomotive Open System ARchitecture) are designed, and a vehicular electronic control unit control model is graphically established. According to a designed code generation template, an available control/simulation code framework is generated using RTW (real time workshop), a code generation mechanism, the operating system and underlying drive are added into a compiler to implement a function library or source code, and conversion of different ECU (electronic control unit) executable codes meeting the specifications above is compete. The trouble of manually compiling the codes is avoided, fast generation of the codes is realized, development cycle is accelerated, expertise requirements on developers are lowered, and code reliability is improved.

Description

Technical field [0001] The invention relates to the technical field of automotive electronic rapid prototyping and code generation, in particular to an automotive code conversion method. Background technique [0002] Facing the current requirements of reliability, consistency, interchangeability, and high efficiency of embedded software for automotive electronic control units. At present, the tools used to generate embedded software code for automotive electronic control units are mainly foreign special tools. These tools often rely on the special hardware and operating environment of the development company. The generated code cannot be standardized and unified, which limits the consistency and availability of the industry. Interchangeability development requirements. It is the consensus of the industry to design a code generation method and system that is compatible with commonly used mathematical modeling and simulation tools, and has scalability and openness. [0003] The dev...
