摘　　要：利用AVR单片机的TWI总线构建了汽车车身电控系统的模块化构架。利用TWI总线定义了数据传输协议,建立了基于TWI的通讯信道,实现了数据在主从模块之间的实时通讯。将总线节点尽可能多地贴近车用电器,进而减少车身线束与总线通讯成本。A module framed structure for electrical control systems of vehicle bodies is constructed based on TWI bus of AVR single chip in this paper. The data transmission protocol is defined, TWI-based communication channel is built, and real-time data communication between host module and slaver modules is got. The bus nodes are designed to close to the appliances as nearly as possible, which contributes to reduce the wiring harness and communication costs
