摘要
为简化汽车车身线束、提高电控单元信息利用率和实现共享传输大批量数据信息,本文采用现场总线中CAN总线技术和ARM7内核的微处理器设计了汽车电子控制系统;详细介绍了汽车电子控制系统单元的控制模块、CAN通信模块的硬件设计及软件分析;同时给出了带ARM7内核的控制实例。通过实践证明,设计的汽车电子控制系统单元空间小、实效性高、抗干扰能力强,符合汽车网络技术的新要求。
The system of car electrical control units, which is based on CAN bus of field-bus control system and ARM7 technology, is designed to simplify the car wires, advance the information＇s usage of car electrical control units, and realize the share and transmission of digital data. And the system control unit of the car electric was well introduced, including the design of control module and communication module, and application with ARM7 unit was given in this paper. With practice testified, this car control electric system needs small unit space, and has a high effect of actuality and strong ability of anti-interference, which all accord with the desire of car-bus technology.
