Description: CAN，全称“Controller Area Network”，即控制器局域网，是国际上应用最广泛的现场总线之一。最初，CAN被设计作为汽车环境中的微控制器通讯，在车载各电子控制装置ECU之间交换信息，形成汽车电子控制网络。比如：发动机管理系统、变速箱控制器、仪表装备、电子主干系统中，均嵌入CAN控制装置。 -CAN, full name of the " Controller Area Network" , the Controller Area Network, is internationally the most widely used field bus. Initially, CAN is designed as a vehicle environment, the micro-controller communications, in-vehicle electronic control unit ECU of the exchange of information between the formation of automotive electronic control network. For example: engine management systems, transmission controllers, instrumentation and equipment, electronic backbone of the system are embedded CAN control. Platform: |
