汽车电子燃油表的设计与匹配

Design and Matching of Automotive Electronic Fuel Meter

汽车燃油表能够准确地测量和显示油箱内的燃油量,驾驶员根据燃油表的显示值来判断车辆的续航里程。由于很多车型燃油表软件控制策略不完善,加之油箱的造型和安装位置比较特殊,造成燃油表在车辆使用过程中出现指示偏差的现象,导致用户较大的抱怨。针对以上问题,从仪表软件逻辑及硬件电路进行系统的分析和改进,使仪表的指示精度和合理性有了极大的提高。

Automotive fuel meter can measure and display the flue quantity in the tank acurately, and the driver estimates how many kilometers that the vehicle can run. Because a good many of vehicles＇ control strategy was not perfect, at the same time, the shape and install position of tank were rather special, all of that resulted deviation of indication in ttle process of using, which made a lot of user＇ s complain. In view of the above problems, from the logic of software and hardware circuit making system analysis and improvement, the display＇ s precision and rational were greatly improved.
