范文编号:DQ182 范文字数:17224,页数:45 摘 要 现代汽车中,中高端的汽车都有方向盘多功能按键,以便于司机操作,提高行车安全。多功能方向盘往往有很多按键,往往不能解决减少线束的问题,而过多的线束影响了方向盘的转向和按键的安装以及维修的困难。事实上,在现代汽车中,采用总线的意义已远远超出节省电线的范围,它已成为车内各零部件实施信息交互的标准接口。LIN总线是一种低成本的串行通信网络,目标应用主要在低端系统。利用LIN总线设计多功能方向盘的方案,可以在不改变原来方向盘的机械设计上增加多功能按键功能,减少研发成本,减少线束,还为提高司机行车的安全性及便利性,具有即插即拔的特性,对以后设备的维护和升级提供有利的条件。
Abstract Modern vehicles, the high-end multi-function steering wheel, the car has a button for the drivers to improve driving safety. Multi-function steering wheel are a lot of buttons, often reduce the wiring harness can not solve the problem, and excessive influence of the steering wheel harness Turn key installation and maintenance difficulties. In fact, modern vehicles, the significance of using the bus wires have been far beyond the scope of savings, it has become a vehicle to implement the various components of the standard interface for information exchange. LIN bus is a low-cost serial communication network, the target application mainly in the low-end systems. LIN bus design using multi-function steering wheel of the program, without changing the mechanical design of the original steering wheel multi-function button to add functionality, reduce development costs, reduce wiring harness, but also to improve road safety and driver convenience, with Plug pull characteristics, on the future maintenance and upgrading of equipment to provide favorable conditions.
