基于Simulink/Stateflow的汽车转向灯控制系统的研究

Research on Vehicle Turn Lamp Control System Based on Simulink/Stateflow

随着汽车电子软件技术的快速发展,传统手写代码的方式已经不能满足代码数量及质量的要求。采用模型设计的方式,基于Simulink/Stateflow工具箱对汽车转向灯控制系统进行建模仿真,使控制算法模型自动生成C代码,下载到硬件电路板中,实测波形与仿真波形一致。基于模型的开发方式前期不依赖硬件平台,开发效率高,避免了传统手写代码开发周期长,一般需要重复多次才能成功的弊端。

With the rapid development of automotive electronic software technology, the traditional handwritten code method can not meet the requirements of the code quantity and code quality. The model design method was adopted,modeling and simulation for the vehicle turn lamp control system was done based on Simulink/Stateflow toolbox. Then, the control algorithm model was automatically generated into C code and downloaded to the hardware circuit board, and the measured waveform was consistent with the simulated waveform. The model-based development method does not rely on the hardware platform in the early stage with high development efficiency, avoiding the disadvantages of traditional handwritten code which needs long development cycle and generally needs to repeat many times to succeed.
