Research of Vehicle Body Electrical Control Technology Based on TWI Bus

Abstract

随着人们对汽车舒适性、智能性以及节能环保的要求不断提高,越来越多的电器设备被运用到汽车上,传统的点对点配电方式必然导致整车线束复杂庞大,占用更多的车内空间。为了解决上述问题,现代汽车设计时都采用了串行总线的方式控制车身电器设备,目前主流使用的总线是CAN总线,CAN总线有很多适应汽车电气控制的优点,但是对于许多微处理器来说,必须使用专门的接口芯片才能进行CAN总线通讯,这使得在设计时芯片的选择性不够友好,一定程度上限制了使用,也提高了成本。针对上述情况,本文尝试着将TWI总线技术用于汽车车身电气控制,该总线系统采用通用的嵌入式芯片即可实现总线协议处理及发送等关键环节,可以将总线节点尽可能多地贴...With the people’s requirement of car’s comfort, Intelligence, energy conservation and environmental protection developing, more and more electrical equipments are applied to the car. Traditional peer-to-peer distribution methods will inevitably lead to the vehicle’s wiring harness and complicated. It also take up more space inside the car. In order to solve the problem that we have talked above, m...学位:工程硕士院系专业:物理与机电工程学院_机械工程学号:1992010115274
