摘要
为了提高控制电路的可靠性和抗干扰性以及控制的准确性,结合目前汽车控制中原理相似的电路,对控制电路进行了重新设计。简要说明了DSP处理器的主要功能和软件控制流程,阐述和分析了目前应用比较广泛的电控悬架的基本原理和主要车高传感器的工作原理;并通过使用仿真软件Multisim,对车身高度检测信号的输出波形进行了验证。结果表明,所涉及电路能够保证信号的可靠性,并能够基本满足控制系统对电路的要求。
In order to enhance the reliability and anti-interference capability of the control circuit as well as the control precision,by combining the circuits with similar principle existing in automotive control,the control circuit has been redesigned.The main functions and software control flowchart of the DSP processor are described briefly,and the basic principle of the widely applied electric controlled suspension at present as well as the operational principle of the main sensors of vehicle height are described and analyzed.Through simulation software Multisim,the output waveform of the detected signal from vehicle height sensor is verified.The result shows that the circuits involved ensure the reliability of the signals,and basically satisfy the requirement of the control system.
