摘要
车速里程表是汽车必备仪表之一,是为驾驶员提供车辆当前车速及里程信息的重要仪表。按照工作原理车速里程表可分为机械式和电子式两种,随着汽车技术的不断发展,市场上大多数车速里程表为电子式。本文主要以某种轻卡上用的车速里程表为例分析了电子式的车速里程表的工作原理、速比的计算方法及显示要求等。
The speedometer is one of the essential instruments and the important instrument to show the current vehicle speed and mileage information for driver. According to the working principle of speedometer,it can be divided into two kinds which are mechanical and electronic. Along with the development of automobile technology,most speedometers used in market are electronic. Taking the speedometer used in a light truck as example,this paper mainly analyzes the working principle of electronic speedometer,calculation method of speed ratio and display requirements.
