The invention discloses a method capable of accurately measuring and displaying oil mass of an oil tank, belongs to the technical field of oil mass measurement of the oil tank, and particularly relates to a method for confirming a vehicle to which the oil tank is applied, carrying out a V-H test at different angles for the vehicle to which the oil tank is applied, and setting an instrument oil mass jump point according to V-H obtained by the oil tank in a horizontal state. The oil pump designs an oil pump liquid level sensor according to the V-H and the jump point to obtain H-R, the instrument judges whether the angle is larger than or equal to 5 degrees or not according to angle signals, if not, oil quantity information is obtained through the instrument according to the V-H-R relation in the horizontal state, if yes, the oil quantity information is not updated, judgment is conducted after two minutes, and if yes, the oil pump liquid level sensor is not updated; if yes, the instrument calculates inclination angles according to the angle coefficient, oil tanks V-H with similar inclination angles are selected, and oil quantity information is obtained according to oil pump resistance value information at the moment; the method can solve the problems of inaccurate instrument fuel quantity display and jumping under the inclination angle of the fuel tank, so that the fuel quantity display of the fuel tank can be more accurate under different gradients, and the user experience can be greatly improved.
本发明公开了一种能精确测量并显示油箱油量的方法,属于油箱油量测量技术领域,具体为确认油箱所应用的交通工具,针对油箱所应用的交通工具,在不同角度下进行V‑H试验,根据水平状态下油箱得出的V‑H,设定仪表油量跳变点,油泵依据V‑H及跳变点设计油泵液位传感器得出H‑R,仪表依据角度信号,判断是否角度≥5°,若为否,则依据在水平状态下V‑H‑R关系仪表得出油量信息,若为是,则不对油量信息进行更新,两分钟之后再进行判断,若为是,则仪表依据角度系数计算倾斜角度,选择倾斜角度相近的油箱V‑H,根据此时油泵阻值信息得到油量信息;本方法能够解决油箱在倾斜角度下仪表油量显示不准及跳变问题,使得在不同坡度下,油箱油量显示能够更加准确,能够大大改善用户感受。
