The invention discloses a method for accurately displaying the remaining oil quantity of a vehicle instrument in a driving state, which is characterized in that the oil injection quantity data of an engine ECU (Electronic Control Unit) in the driving state is directly acquired and is filtered, so that the instability caused by fluctuation of resistance value data of an oil floater due to mechanical vibration of the engine and the like is reduced, and meanwhile, the residual oil quantity of the vehicle instrument in the driving state is accurately displayed. The fuel quantity displayed by the vehicle fuel gauge is accurately calculated through the vehicle fuel gauge descending damping time and the vehicle fuel gauge descending speed, accurate display of the remaining fuel is guaranteed, and a user can accurately judge the remaining fuel and the endurance mileage of the vehicle.

    本发明公开了一种行驶状态中车辆仪表剩余油量精确显示方法,本发明通过直接采集行驶状态中发动机ECU喷油量数据,并对发动机ECU喷油量数据进行滤波处理,降低由于发动机等机械震动导致油浮子阻值数据波动带来的不稳定,同时,通过车辆燃油表下降阻尼时间和车辆燃油表下降速率,去精确计算车辆燃油表显示的油量,保证了剩余燃油的精确显示,使用户能准确判定车辆剩余燃油及续航里程。
