全液晶仪表LVDS升级方案

LVDS Upgrade Scheme of All LCD Meter

本文从硬件设计和软件设计两方面进行阐述,针对全液晶仪表软件升级操作困难、升级成本高等问题,规划设计了一种全新的仪表升级方式,并成功应用到车型项目开发中。仪表LVDS升级方案:在信息娱乐系统规划时,进行仪表和中控主机LVDS芯片的适配,利用LVDS线同时实现导航投图和软件升级功能。该方案在车型项目上成功实施,不但简化了仪表升级方式,降低了单车成本,也为后续车型其它电子零部件的升级及诊断开发积累了经验、奠定了基础。

In this paper,the hardware design and software design are described.Aiming at the problems of difficult operation and high upgrade cost of all LCD instrument software,a new instrument upgrade method is planned and designed,which is successfully applied to the vehicle project development.Instrument LVDS upgrade scheme:in the planning of information and entertainment system,the instrument and the central control host LVDS chip are adapted,and the LVDS line is used to realize the navigation mapping and software upgrade functions at the same time.The scheme is successfully implemented in the vehicle project,which not only simplifies the instrument upgrade mode and reduces the cost of single vehicle,but also accumulates experience and lays a foundation for the upgrade and diagnosis development of other electronic parts of the follow-up vehicle.
