1、前言
汽车仪表盘是反映车辆各系统工作状况的装置。常见的有燃油指示灯、清洗液指示灯、电子油门指示灯、前后雾灯指示灯及报警灯。不同汽车的仪表不尽相同。但是一般汽车的常规仪表有车速里程表、转速表、机油压力表、水温表、燃油表、充电表等。现代汽车仪表盘的面膜下制作了各式各样的指示灯或警报灯，例如冷却液液面警报灯、燃油量指示灯、清洗器液面指示灯、充电指示灯、远近光变光指示灯、变速器挡位指示灯、制动防抱死系统 (ABS) 指示灯、驱动力控制指示灯、安全气囊 (SRS) 警报灯等。
2、方案概述
Ameya360 汽车仪表盘解决方案针对传统仪表和现有仪表存在的不足，提出了一种新型的仪表设计方案，采用 arm 处理器为核心的硬件平台和以嵌入式 linux 系统为核心的软件平台，并在此基础上采用开放源代码的图形界面库 qt 开发仪表终端应用程序。该仪表可读性好，读数精度高，在可移植性、可维护性和成本方面都得到了良好的改善，具有较大的科研价值和商业使用价值
车载仪表的基本设计思想是将监控系统上安装的各种传感器采集到的数据进行智能化的处理，然后在运行于嵌入式 linux 系统的使用 qt 设计的虚拟仪表盘上进行显示，以便于监测各系统的工作状况。
