摘要
现代汽车将会越来越多地装用各种用途的电子化仪表,造型新颖和功能强大的电子化仪表显示装置,将是今后汽车仪表盘的发展趋势和潮流。本文介绍了以微处理器及其扩展电路构成的组合汽车仪表盘的设计思想及软件、硬件设计技术。本汽车仪表盘将步进电机指针式仪表和液晶显示器的虚拟仪表结合起来,并可作为汽车CAN总线中的一个从节点,可实现汽车各种运行工况的实时显示等多种功能。
There are more and more electronic instruments with different functions to be used in modern automotives. The display devices with modern designs and powerful functions are the trends of automobile dashboards in the future. A combined type car dashboard based on the microprocessor and its extension circuits is introduced in this paper , including its design idea, the software and hardware design technologies . This combined type car dashboard , which consists of the stepper motor pointer and LCD virtual instrument, can serve as a slave node in vehicle CAN bus. So it can realize the real-time display of various vehicle operating conditions and so on.
