汽车节油提示方法
摘要：
本发明提供一种汽车节油提示方法，计算机中存有发动机转速和车速计算模块、车速与档位比对表(1)、车速标志位查询表(2)、档位查询表(3)；采集发动机转速和车速脉冲并计算转速V0和车速V1，将V0、V1分别存放在RAM中；根据V0和V1计算变速比B，通过表(3)查找对应标准变速比X，进而查找对应档位D1，将D1保存在RAM中；根据实测车速V1查找表(2)中对应的标准车速V2，进而查找对应的车速标志位Z，选中的Z由0变为1；对应的(1)中的车速标志位Z也由0变为1，由此查找到档位值D2；将表(3)中实测档位D1与表(1)中查找的D2中的最高档位比较；D1＝D2不提示，如果D1≠D2时，再检测中断信号，若没有中断信号，D1＜D2输出“加档”提示。
摘要（英）：

An oil-saving prompting method for car includes such steps as storing a calculation module for the rotation speed of engine and car speed, the car speed-gear position reference table A, car speed flag bit inquiring table B and gear position inquiring table C in computer, acquiring pulses about the rotation speed of engine and car speed, calculating the rotation speed V0 and car speed V1, storing them in RAM, calculating speed varying ratio B, searching relative standard speed varying ratio X from table C, searching relative gear position D1, storing it in RAM, searching standard car speed V2 from table B, searching relative car speed flag Z, changing the Z from 0 to 1, Changing the relative flag Z in table A from 0 to 1, searching gear position D2, comparing D1 with D2, not prompting if D1=D2, or detecting interrupt signal if not, and prompting for increasing gear position if there is no interrupt signal and D1 is less than D2.
